Step-by-step explanation:

Percentage of boys = 60%

Percentage of girls = 100 - 60 = 40%

Percentage of boys that arrive by car

= 20% of 60%

= 0.2 x 60 = 12%

Percentage of girls that arrive by car

= 60% of 40%

= 0.6 x 40

= 24%

Total Percentage of children arrive by car

= 12 + 24

= 36%

P(Arrive by car)

= 36%

= 0.36

Step-by-step explanation:

Answer:

Final answer is Volume = 60 cubic centimeters.

Step-by-step explanation:

Given that area of the base of the given picture = 10 square centimeters.

Given that height of the given picture = 6 centimeters.

Now we need to find the volume of the given solid.

So we just need to multiply the base area with the height to get the volume.

Volume = (Area of base) ( height)

Volume = (10 square centimeters) ( 6 centimeters)

Volume = 60 cubic centimeters

Hence final answer is Volume = 60 cubic centimeters.

Answer:

C. 1/4

Step-by-step explanation:

There are in total 12 marbles in the bag.  So the probability of picking a red marble is 3/12.  If you simplify that, you get 1/4.

The question is not perfectly clear, but I assume you're asking something like this:

in a rectangle, the area is given by [tex]A=wl[/tex]

where A is the area, w is the width and l is the length.

So, if we know that the width is 7 and we let x be the length of the rectangle, we have

[tex]A=7x[/tex]

If you need to solve this for x, divide both sides by 7:

[tex]x=\dfrac{A}{7}[/tex]

The length of a rectangular computer screen can be determined by the equation x = A / 7.

To find the length of a rectangular computer screen given its area (A) and width (7 inches), you can use the formula for the area of a rectangle:

Area = Length × Width

Given:

Area = A square inches

Width = 7 inches

We need to find the length, denoted by x. By rearranging the area formula, we get:

x = Area / Width

Substitute the given values:

x = A / 7

Therefore, the length of the computer screen in inches can be found using the equation x = A / 7.

Answer:

x = 2

Step-by-step explanation:

A line with an undefined slope indicates that the line is vertical and parallel to the y- axis.

The equation of a vertical line is

x = c

Where c is the value of the x- coordinates the line passes through.

The line passes through (2, 5) with x- coordinate 2, hence

x = 2 ← equation of line

Answer:

n = 62 + x

Step-by-step explanation:

From the problem given, it is clear that the orange has LESS calories than a nectarine. HOW much less? "x" less.

Also, orange has 62 calories. So, nectarine MUST HAVE 62 + x calories.

If we let nectarine's calories be n, we can write:

n = 62 + x

Since it is not perfectly straight it’s not linear so

*nonlinear association

The line goes down not up so it’s

*negative association

If your teacher wants to count the point outside of the regular line it would be no association

The two that most fit this graph are nonlinear and negative association

Answer:

There is a non linear association and negative association between variable A and B.

Step-by-step explanation:

A nonlinear relationship between two entities indicates that a change in one entity does not correspond with the constant change in the other entity.

Here, we can see the scatter plot that shows a non linear relationship.

There also exists a negative association between variable A and variable B. We can see that B increases as A increases, but points do not lie on a straight line.

Therefore, there is a non linear association and negative association between variable A and B.

Answer:

The graph in the bottom right (The circle) is not a function

Step-by-step explanation:

As the circle has multiple y values for each x value, it is not a function. In other words, that graph fails the vertical line test.

Answer:

IV graph

Step-by-step explanation:

Function: It is relation between x and y.For each x, there is  a unique value of y.

Only one output for one input.

One value of x cannot have more than one images.

Vertical line test:

When we draw a vertical line passing through any given  value of x and cut the curve more than one  points then, the curve does not represents the function.

When a vertical line cuts the curve at one point then, the curve represents the function.

In I graph, We can see that

Image of 1 is 2.

Image of 2 is 1.

Image of -2 is 1.

There is only one output for input.

Hence, it represents the function.

In II graph,

By vertical line test, when we draw a vertical line x=1 then it cuts the graph at one point only.

Hence, it represents the function.

In III graph,

Image of 1 is 1.

Image of 0 is 2.

Image of -1 is 3.

Image of -2 is 4.

There is only one output for 1 input.

Hence, it represents the function.

In IV graph,

When we draw a vertical line x=1 then , it cuts the curve at two points.

Therefore, given circle does not represents the function.

Answer:

The equation of the graph below is y = 0.5 csc[0.5(x + π/2)] - 1 ⇒ 3rd answer

Step-by-step explanation:

* Lets revise the trigonometry transformation

- If the equation is y = A csc(B(x + C)) + D

# Amplitude is A

- The Amplitude is the height from the center line to the peak .

  Or we can measure the height from highest to lowest points and

  divide that by 2

# period is 2π/B

- The Period goes from one peak to the next

# phase shift is C (positive is to the left)

- The Phase Shift is how far the function is shifted horizontally

  from the usual position.

# vertical shift is D

- The Vertical Shift is how far the function is shifted vertically from

 the usual position.

- If y = csc(x)

∴ A = 1 , B = 1 , C = 0 , D = 0

- That means the amplitude is 1, the period is 2π, no phase shift

 or vertical shift

* Now lets solve the problem

- From the graph

# The amplitude = (-0.5 - -1.5)/2 = 0.5

∴ A = 0.5

# The period is from 2.5π to -1.5π

∴ The period is 4π

∵ The period = 2π/B

∴ 4π = 2π/B ⇒ by cross multiplication

∴ B = 2π/4π = 1/2 = 0.5

* There is only one answer has A = 0.5 and B = 0.5

∴ y = 0.5 csc[0.5(x + π/2)] - 1

* The equation of the graph below is 0.5 csc[0.5(x + π/2)] - 1

* For more understand look to the color graph

- The blue graph is y = csc(x)

- The green graph is y = 0.5 csc[0.5(x + π/2)] - 1

Answer:

C. y = 0.5csc [0.5 (x + pi/2)] - 1

The density of maple trees per square kilometer for the cosidered rectangular patch of land is 283 maple trees/sq. km approximately.

Density is like rate. It tells you how much of a thing is available for each unit other thing which contains the first thing.

Density = (Total amount available)/(total space which contains that amount)

For this case, we're specified that:

Density of trees will be expressed in terms of number of trees per unit area

Area of the considered land = [tex]3 \times 4 = 12 \: \rm km^2[/tex]

Thus, the density of the maple trees in terms of maple trees per sq. kilometers is:

I set up an equal proportion [tex]\frac{100}{0.25} = \frac{80}{x}[/tex]

cross multiply to get 80 * 0.25 = 100x

20 = 100x; divide both sides by 100

0.2 = x so the answer is choice B

Answer:

B. 0.2 meters.

Step-by-step explanation:

Let x represent meters of spring stretched by 80 newtons.

We have been given that a force of 100 newtons will stretch a spring 0.25 meters.

We will use Hooke's law, which states that the force needed to compress or extend a spring is directly proportional to the distance we stretch it.[tex]N=kx[/tex], where,

N = Force in Newtons,

k = The spring constant,

x = Amount of extension in meters.

Let us find spring constant by substituting [tex]N=100[/tex] and [tex]x=0.25[/tex].

[tex]100=k*0.25[/tex]

[tex]\frac{100}{0.25}=\frac{k*0.25}{0.25}[/tex]

[tex]400=k[/tex]

So, our equation would be [tex]N=400x[/tex].

Now, we will substitute [tex]N=80[/tex] in our equation to find x.

[tex]80=400x[/tex]

Upon dividing both sides of our equation by 400 we will get,

[tex]\frac{80}{400}=\frac{400x}{400}[/tex]

[tex]\frac{1}{5}=x[/tex]

[tex]0.2=x[/tex]

Therefore, the force of 80 newtons will stretch the spring 0.2 meters and option B is the correct choice.

Answer:

-4y -7

Step-by-step explanation:

−4y−4+(−3)

The terms -4 and -3 are the like terms.  When we add them together we get

-4 +-3 = -7

-4y + -7

or -4y -7

Final answer:

To combine like terms in the expression −4y−4+(−3), you combine the constants −4 and −3 to get −4y - 7.

Explanation:

To combine the like terms in the expression −4y−4+(−3), let's first identify the like terms. Here, since we only have one variable term −4y, it doesn't combine with any other, but we do have constant terms that we can combine: −4 and (−3).

When combining these constants, we treat the parentheses as a multiplication by -1 due to the negative sign in front of the 3. Thus, the expression becomes:

−4y − 4 − 3

Now we simply combine the constants:

−4y - 7

So the equivalent expression after combining like terms is −4y - 7.

Answer:

Step-by-step explanation:

(a)

Using the relationship

distance = speed (s) × time (t) ← speed is rate of change, then

speed = [tex]\frac{distance}{time}[/tex], thus

[tex]\frac{54}{0.75}[/tex] = 72

[tex]\frac{216}{3}[/tex] = 72

[tex]\frac{252}{3.5}[/tex] = 72

[tex]\frac{432}{6}[/tex] = 72

[tex]\frac{576}{8}[/tex] = 72

Thus rate of change is constant, hence

Answer: Last Option

[tex]y> | x + 1 | +3[/tex]

Step-by-step explanation:

First we must identify the function shown in the graph.

It is a function of absolute value whose vertex is in the point (-1, 3)

The absolute value parent function is:

[tex]h(x) = | x |[/tex]. And it has its vertex in (0, 0)

The function shown in the graph is the function h(x) displaced 1 unit to the left and 3 units to the top.

Therefore the function shown in the graph [tex]f(x) = h (x + 1) +3[/tex]

[tex]f (x) = | x + 1 | +3[/tex].

Then, the region shaded in the graph are all the values of y that are above the graph of [tex]f (x) = | x + 1 | +3[/tex]

That is, the region is formed by all values where y is greater than [tex]f (x) = | x + 1 | +3[/tex]

Then the inequality is:

[tex]y> | x + 1 | +3[/tex]

Number 2 is the answer

Answer:

Unfortunately, your picture doesn't show all the graphs of the possible answers.

However, the graph should look like the one I attached, passing by the (5,0) point.  Which is logic since a value of 5 for x would make the y the cubic root of 0... which is 0.

When trying to identify a graph of a formula, always try to see which values of x could make y = 0 or what would happen to y if x = 0, that will always give you a pretty good idea of which graph to choose from.

Answer:D

Step-by-step explanation:

The probability that Jase makes an A given that he studies for the geometry test is [tex]\(\frac{68}{75}\)[/tex].

Let's denote the event that Jase studies for the geometry test as [tex]\(S\)[/tex] and the event that he makes an A as [tex]\(A\)[/tex].

The probability that Jase studies for his geometry test is given as [tex]\(P(S) = \frac{15}{16}\)[/tex].

The probability that Jase studies and makes an A is given as [tex]\(P(S \cap A) = \frac{17}{20}\).[/tex]

To find the probability that he makes an A given that he studies [tex](\(P(A|S)\))[/tex], we use the conditional probability formula:

[tex]\[ P(A|S) = \frac{P(S \cap A)}{P(S)} \][/tex]

Substitute the given values:

[tex]\[ P(A|S) = \frac{\frac{17}{20}}{\frac{15}{16}} \][/tex]

To divide by a fraction, multiply by its reciprocal:

[tex]\[ P(A|S) = \frac{17}{20} \times \frac{16}{15} \][/tex]

Simplify the expression:

[tex]\[ P(A|S) = \frac{17 \times 16}{20 \times 15} \][/tex]

[tex]\[ P(A|S) = \frac{272}{300} \][/tex]

Now, simplify the fraction:

[tex]\[ P(A|S) = \frac{68}{75} \][/tex]

So, the probability that Jase makes an A given that he studies for the geometry test is [tex]\(\frac{68}{75}\)[/tex].

[tex]\((-5)(-4) - 6 - 4(6) = -10\)[/tex]

[tex]\((-5)(-4) = 20\)[/tex]

Subtract the result from step 1 from the second term:

[tex]\(20 - 6\)[/tex]

Multiply the number 4 by 6:

[tex]\(4 \times 6 = 24\)[/tex]

Subtract the result from step 3 from the result in step 2:

He grows fruit on 6 acres of land.

And he grows flowers on 2 acres of land.

Total farming acres are = [tex]7+6+2=15[/tex] acres.

Now, we have to find what the theoretical probability that the ladybug was not found within the acres of flowers. This means it was not found in 2 acres of land. It must have been in 13 acres of land.

So, probability will be : [tex]\frac{13}{15} \times100[/tex] = 86.66% ≈86.7%

Answer: d

Step-by-step explanation:

Answer:

Step-by-step explanation:

A) The equation for the volume of a sphere is [tex]V=\frac{4}{3} \pi r^{3}[/tex]

As the diameter of each ball is 3 inches, that would mean that the radius of each is 1.5 inches.

Now we can plug our value into the equation

[tex]V=\frac{4}{3} \pi (1.5)^{3}[/tex]

This would simplify to

V = 14.12716694 [tex] in^{3}[/tex]

B) The equation for the volume of a cylinder is [tex]V=d\pi h[/tex]

As there are 3 balls in a container and the diameter of each is 3, that would mean that the height is 9 inches

Now we can plug in our values into the equation

[tex]V = (3)(9)\pi[/tex]

This would mean that this equation would simplify to

[tex]V = [/tex] 27\pi [tex]in^{3}[/tex]

C) To find the empty space, we must take the total volume, the volume of the cylinder, and subtract the volume of the tennis balls

This would mean that the equation would look like this

[tex](27\pi)-(3(\frac{4}{3} \pi (1.5)^{3})) [/tex]

This would simplify to

42.41150082 [tex]in^{3}[/tex] of empty space.

Answer:

Step-by-step explanation:

Givens

First, we find the volum of each tennis ball.

Notice that they have spherical form, so their volume is defined by

[tex]V=\frac{4}{3} \pi r^{3}[/tex]

Where [tex]r=\frac{d}{2}=\frac{3 in }{2}=1.5in[/tex]

Replacing the radius and using [tex]\pi \approx 3.14[/tex], we have

[tex]V=\frac{4}{3}(3.14)(1.5in)^{3}=14.13 \ in^{3}[/tex]

Therefore, the volume of each tennis vall is 14.13 cubic inches, approximately.

Assuming that the diameter of each ball is congruent with the diameter of the can, we have the volume of a cylinder defined by

[tex]V=\pi r^{2}h[/tex]

Where, [tex]r=1.5in[/tex] and [tex]h= 3(3in)=9in[/tex], because each can has three balls, and the height is the sum of all three diameters.

Replacing, we have

[tex]V=3.14(1.5in)^{2} (9in)=63.59 in^{3}[/tex]

Therefore, the volume of each can is 63.59 cubic inches, approximately.

Now, notice that between the can and the tennis balls thereis empty space, because balls are spherical and cans are cylindric.

Let's find the difference between their volumes:

[tex]V_{empy}=63.59-14.13= 49.46 in^{3}[/tex]

Therefore, there are 49.46 cubic inches of empty space between the tennis balls and the cans.

Odd numbers take the form [tex]2n-1[/tex], where [tex]n\ge1[/tex] is an integer. When [tex]n=400[/tex], the last odd number would be 799. So we're adding

[tex]S=1+3+5+\cdots+795+797+799[/tex]

By reversing the order of terms, we have

[tex]S=799+797+795+\cdots+5+3+1[/tex]

and we can pair up terms in both sums at the same position to write

[tex]2S=(1+799)+(3+797)+(5+795)+\cdots(795+5)+(797+3)+(799+1)[/tex]

so that we are basically adding 400 copies of 800, and from there we can find the value of the sum right away:

[tex]2S=400\cdot800\implies S=160,000[/tex]

###

We could also make use of the formulas,

[tex]\displaystyle\sum_{i=1}^n1=n[/tex]

[tex]\displaystyle\sum_{i=1}^ni=\dfrac{n(n+1)}2[/tex]

We have

[tex]S=\displaystyle\sum_{i=1}^{400}(2i-1)=2\sum_{i=1}^{400}i-\sum_{i=1}^{400}1=400(400+1)-400=400^2=160,000[/tex]
