Fifty percent of the surface area of the bread is crust. What is the height h?

Answer:

(a) Option A. independent

(b) [tex]P(A\ and\ B) = 0.0312[/tex]

Step-by-step explanation:

Two events A and B are considered dependent if the occurrence of one affects the probability of occurrence of another.

In this case, the events are independent because the birth of a girl or a boy does not affect the probability of obtaining a 1 by throwing a 16-sided die.

In the same way, throwing a die and obtaining the number 1 does not affect the probability that a baby is a girl or a boy.

When two events are independent then

[tex]P(A\ and\ B) = P(A)*P(B)[/tex]

The probability that a baby is a girl is

[tex]P(A) = 0.5[/tex]

The probability of obtaining a 1 when casting a 16-sided die is:

[tex]P(B) = \frac{1}{16}[/tex]

Then:

[tex]P(A\ and\ B) = 0.5 * \frac{1}{16}[/tex]

[tex]P(A\ and\ B) = 0.0312[/tex]

Answer:

choice c is believe is the answer

Step-by-step explanation:

Applying the Pythagorean theorem, the distance between kensington and greenwich is: b. 20√5 mi.

To solve a right triangle, where a and b are the legs and c is the longest side (hypotenuse), the Pythagorean theorem states that, c = √(a² + b²).

Apply the Pythagorean theorem to find the distance:

Distance between kensington and greenwich = √(40² + 20²)

= √(1,600 + 400)

= √2,000

= 20√5 mi.

Answer: 14.555

Step-by-step explanation: so you take $3.85 multiplied by 3 because they bought 3 toy cars plus a $4.56 and take the answer of that and divide by 2 because they split the cost. Hope this helps

Answer:

each girl had to pay around $8.06

Step-by-step explanation:

They bought 3 toy cars and each car was $3.85.

You have to multiply $3.85*3 which is $11.55.

Then add the $4.56 of shipping fee which is $16.11.

since the 2 girls shared the total cost, divide 16.11/2

16.11/2= $8.06

Answer:

1. Area of the land which can be ploughed daily is 50 hectares (and 70 hectares at higher rate)

2. Area of the field is 700 hectares

Step-by-step explanation:

Let x hectares be the number of hectares the farmers  normally ploughed in a day. At this rate, they will complete the work in 14 days, so they have to plough

[tex]14\cdot x=14x\ hectares.[/tex]  

Then x+20 hectares is the number of hectares the farmers ploughed in a day when they increased their productivity of work. At this rate, they will complete the work in 10 days, so they have to plough

[tex]10\cdot (x+20)=10(x+20)\ hectares.[/tex]

The work is the same, so

[tex]14x=10(x+20)\\ \\14x=10x+200\\ \\14x-10x=200\\ \\4x=200\\ \\x=50[/tex]

Ploughing 50 hectares each day 14 days in a row they will plough

[tex]14\cdot 50=700\ hectares[/tex]

Answer:

The sum (answer) is [-1, 2, 1, 9].

Step-by-step explanation:

Here we're asked to sum up two matrices of the same dimensions (1 by 4).

The value in the first matrix, first column, is 1; that in the second matrix, first column, is -2.  Combining 1 and -2, we get -1, which is the first column value in the answer matrix.

Continuing in the same manner:  -4 + 6 = 2; 3 - 2 = 1; and 5 + 4 = 9.

The sum (answer) is [-1, 2, 1, 9].

Answer:

The slope is -2

Step-by-step explanation:

To find the slope of a line when we have 2 points, we use the formula

m = (y2-y1)/(x2-x1)

    = (3-9)/(4-1)

     = -6/3

   -2

The slope of the line is -2

To find the slope of a line using two points, there are many formulas, however the easiest one to use is (rise/run)

The rise is the difference in the Y value and the run is the difference in the X value

(9-3)/(1-4) = (6/-3) = -6/3, which can be simplified to -2

Area of the circle is the area which is occupied by the circle in the two- dimensional plane. The area of the circle is equal to the area of the bottom of the circular swimming pool. Thus the blue paint is total 707.143 square feet.

The diameter of the circular swimming pool is 30 feet.

To find out the square feet of blue the area of the circle has to be calculated.

Area of the circle is the area which is occupied by the circle in the two- dimensional plane. The area of the circle with diameter [tex]d[/tex] can be calculated as,

[tex]A=\pi\times \dfrac{d^2}{4}[/tex]

Put the value of the diameter, we get,

[tex]A=707.143[/tex]

The area of the circle is 707.143 square feet.

[tex]ln(e^x)=ln(3)[/tex]

[tex]x=1.099[/tex]

Step-by-step explanation:

You have the following exponential expression:

[tex]2e^x=6[/tex]

You need to divide both sides of the equation by 2:

[tex]\frac{2e^x}{2}=\frac{6}{2}\\\\e^x=3[/tex]

Now apply the function Natural logarithm to both sides of the function:

[tex]ln(e^x)=ln(3)[/tex]

Note that now the exponential function is transformed into a logarithmic function.

By definition:

[tex]ln(e^x)=x[/tex] Because the base of the Natural logarithm is the Euler's number "e".

Then you can solve for "x":

B. y=2x+1

EXPLANATION

The graph has a y-intercept of 1.

Let y=mx +b be the equation of the straight line graph.

where b=1 is the y-intercept.

We put this value into the equation to get,

y=mx +1.

Thie point (1,3) must also satisfy this line.

3=m(1)+1

m=3-1

m=2

The equation is

y=2x+1

Start with

Add 9 to both sides

[tex]15-\dfrac{2}{3}x<x[/tex]

Add [tex]\frac{2}{3}x[/tex] to both sides

[tex]15<\dfrac{5}{3}x[/tex]

Answer:

A 18° and 72°

Step-by-step explanation:

As you know, the sum of two complementary angles = 90

The ratio 1 : 4 = 1 + 4 = 5

So 90/5 = 18

1 x 18 = 18

4 x 18 = 72

The two complementary angles are  18° and 72°

Answer

A 18° and 72°

Answer:

8

Step-by-step explanation:

hypotenuse = c = 17 feet

Height = a = 9 feet + 6 feet = 15 feet

Children's space = b

a^2 + b^2 = c^2

15^2 + b^2 = 17^2

225 + b^2 = 289                   Subtract 225 from both sides

225-225+b^2=289-225

b^2 = 64                                 Take the square root of both sides.

sqrt(b^2) = sqrt(64)

b = 8

Since each child takes up 1 foot, 8 children can sit on side b.

Step-by-step explanation:

Answer:

Given in the question an expression,

y = 3x/(8+x)

Step1

interchange the variables

x = 3y/(8+y)

Step 2

x(8+y) = 3y

Step 3

8x + xy = 3y

Step 4

8x = 3y - xy

Step 5

8x = y(3 - x)

Step 6

8x = y(3 - x)

Step 7

y = 8x/(3-x)

Step 8

y = f(x^-1) = 8x/(3-x)

So the inverse of  f(x)= 3x/(8+x) is f(x^-1) = 8x/(3-x)

Answer:

It's -6. She did a bunch of weird work under my answer.

Step-by-step explanation:

The x-intercept of the graph of the equation 3x + 12 = -6 can be found by solving for x. Performing the necessary operations we get x=-6, thus, the x-intercept is -6.

To find the x-intercept of the graph of the equation 3x + 12 = -6, let's first solve the equation for x. The x-intercept is the value of x where the graph intersects with the x-axis, this is the point where y = 0. By rearranging the equation, we can first subtract 12 from both sides to get 3x = -18, then divide both sides by 3 to get x = -6. So, the x-intercept of the graph is -6.

Here, we haven't needed to use information about the slope or the y-intercept, which do not affect the x-intercept. The slope of the line determines its steepness and direction, while the y-intercept determines where it crosses the y-axis. These shape the line but will not change where it crosses the x-axis.
