Answer:

A

Step-by-step explanation:

Obviously it's impossible for anyone to measure the weight and length of all US rattlesnakes.

Thus, A is correct.  200 is not a large sample compared to millions or billions of rattlesnakes, but is still a lot more reasonable and workable than attempting to measure ALL US rattlesnakes.

Answer:

8 minutes if Jane was assumed to be stationary

Step-by-step explanation:

The question is on relative speed

First find the distance covered by Jane when Sally left school

Speed=Distance/Time ⇒⇒ Distance=Time×Speed

Time=10minute=10/60 hrs

Jane's speed= 12mph

Distance covered by Jane when Sally left school was= 12 ×10/60 = 2miles

So, when Sally left school, Jane was 2 miles away. To find the time Sally requires to catch up with Jane;

Time=Distance/speed

Time of meeting =2/15 hrs ⇒⇒ 2/15 × 60 =8minutes

A prism is a solid object having two identical bases, hence the same cross section along the length. Prism are called after the name of their base. On the other hand, a rectangular prism is a solid whose base is a rectangle. The surface area of a solid is the total area of its outer surface. For a rectangular prism, we have three characteristic sides, which are height, width and depth. If:

[tex]height=a \\ \\ width=b \\ \\ depth=c[/tex]

Then, from the figure below we have:

[tex](1) \ a\times b=24 \\ \\ (2) \ a\times c=18 \\ \\ (3) \ b\times c=12 \\ \\ \\ From \ 1 \ and \ 3: \\ \\ b=\frac{24}{a}=\frac{12}{c} \therefore 24c=12a \ (4) \\ \\ From \ 2: \\ \\ a=\frac{18}{c} \\ \\ 2 \ into \ 4: \\ \\ 24c=12\times \frac{18}{c} \therefore c^2=9 \therefore \boxed{c=3} \\ \\ \\ c \ into \ 2: \\ \\ a=\frac{18}{3} \therefore \boxed{a=6} \\ \\ \\ c \ into \ 3: \\ \\ b=\frac{12}{3} \therefore \boxed{b=4}[/tex]

Answer:

3/2

Step-by-step explanation:

3/4 plus 3/4 is   3/4 + 3/4 = 6/4, and this reduces to 3/2.

Answer:

1 1/2

Step-by-step explanation:

Adding the numerators, three and three, yields six. The resulting fraction is 6/4. The next step is simplifying this fraction. The numerator is greater than the denominator and this indicates that the answer is more than one. Therefore, the numerator is divided by the denominator, which equals one with a remainder of two. This remaining fractional part, 2/4, is simplified by dividing both numerator and denominator by the greatest common factor, which is 2. This becomes 1/2, for a final answer of 1 1/2.

The width of the rectangle with an area of 121-x^2 square meters and a length of 11 - x meters is represented by the expression 11 + x meters.

The area of a rectangle is the product of its length and width. In this case, the area is given as 121-x^2 square meters, while the length is given as 11 - x meters. To find the expression for the width, we divide the area by the length. Therefore, the width w can be represented by the following equation:

w = \(\frac{Area}{Length}\) = \(\frac{121-x^2}{11-x}\).

Due to the structure of the quadratic area (a perfect square difference) and the linear length (a factor of the quadratic), the equation simplifies to:

w = \(\frac{(11+x)(11-x)}{11-x}\).

Canceling out the common factor (11-x), we are left with:

w = 11 + x.

Thus, the expression representing the width of the rectangle is 11 + x meters.

To find Janak's age, we set up an equation based on the information that his age is twice younger than his father's and six times younger than his sister's with their combined age totaling 118. Upon solving the algebraic equation, we find that Janak is approximately 13 years old.

We are given a problem where Janak is twice younger than his father and six times younger than his sister. The total age of Janak, his father, and his sister is 118 years. To solve for Janak's age, we will use algebra.

Let's assume Janak's age is J, his father's age will be 2J (twice Janak's age), and his sister's age will be 6J (six times Janak's age). We express the total age as the sum of their individual ages:

The equation that represents the total age is:

Combining the terms gives us:

To find Janak's age, we divide both sides of the equation by 9:

After performing the division, we get:

So, Janak is approximately 13 years old.

Answer:

Part 1) [tex][(250)^{2}+(-400)^{2}+(-250)^{2}+(350)^{2}+(100)^{2}+(-50)]=420,000[/tex]

Part 2) The variance is equal to [tex]Variance=70,000[/tex]

Part 3) [tex]Standard\ Deviation=265[/tex]

Step-by-step explanation:

step 1

Find the mean of the areas

we have

[tex][2,400,1,750,1,900,2,500,2,250,2,100][/tex]

To find the mean sum all the values and divide by the number of values

The number of values is 6

so

[tex][2,400+1,750+1,900+2,500+2,250+2,100]/6=2.150[/tex]

The Mean is [tex]2.150[/tex]

step 2

For each number subtract the Mean

[tex][(2,400-2,150),(1,750-2,150),(1,900-2,150),(2,500-2,150),(2,250-2,150),(2,100-2,150)][/tex]

[tex][(250),(-400),(-250),(350),(100),(-50)][/tex]

step 3

Find the Variance

To calculate the Variance, take each difference, square it, and then average the result

[tex][(250)^{2}+(-400)^{2}+(-250)^{2}+(350)^{2}+(100)^{2}+(-50)]=420,000[/tex]

[tex]Variance=420,000/6=70,000[/tex]

step 4

Find the standard deviation

The Standard Deviation is just the square root of Variance

so

[tex]Standard\ Deviation=\sqrt{70,000} =265[/tex]

ANSWER

The solution is (-1,2)

EXPLANATION

The system is:

y = 2x + 4

and

y = 8x + 10

Equate the two:

2x + 4 =8x + 10

Group similar terms:

8x-2x=4-10

Combine similar terms,

6x=-6

Divide both sides by 6.

x=-1

This implies that ,

y=2(-1)+4

y=2

The solution is (-1,2)

Answer:

x=-1

Step-by-step explanation:

y=2x+4

y=8x+10

y is = to both so use them together...

2x+4=8x+10

solve...

-2x both sides

4=6x+10

-10 both sides

-6=6x

divide by 6 both sides

x=-1

The graph representing Sally's distance from Los Angeles should depict a linear decrease from the point (0, 300) with a slope of -60. The line starts at 300 on the y-axis and consistently drops 60 units for every hour of travel time.

To find which graph could represent Sally's distance from Los Angeles in terms of time, we first determine the equation for Sally's journey. Since Sally drives at an average speed of 60 miles per hour, the distance she has driven after t hours is given by the equation d = 300 - 60t, where 300 is the initial distance from Los Angeles, and 60t represents the distance traveled in t hours.

The graph of this equation would be a straight line starting at the point (0, 300) and decreasing with a slope of -60, which represents the rate at which Sally approaches Los Angeles. This line shows how Sally's distance from Los Angeles decreases over time at a constant rate.

Therefore, the appropriate graph should start at 300 on the y-axis and slope downwards to the right, crossing the y-axis at points that are 60 units lower for each additional hour on the x-axis. This will show a linear decrease in distance over time, which corresponds to Sally's constant speed of 60 miles per hour.

Answer: $26

$40*.35=$14 off price of sweater

40-14=$26 sale price

Or

$40*.65=$26 sale price

Answer:

The correct answer is $26.

Step-by-step explanation:

Well, we must first analyze the information we have.

We have a sweater that was marked down 35% off.

We know that the original price of the sweater is $ 40. Now we just have to find out the final price.

But to know that, we must first know what the discount was applied.

And we find out as follows:

[tex]Tax= 40 . 0,35[/tex]

[tex]Tax= 14[/tex]

In this way we show that the price discounted to the sweater was $ 14

Now we just have to make a subtraction between the original price and the discount :

40-14=26

The final price of the sweater is $ 26

Answer:

y = -2x + 16

Step-by-step explanation:

A line perpendicular to y = (1/2)x - 6 would have a slope that is the negative reciprocal of 1/2, that is, a slope of -2.  Here the given point is (h, k):  (6, 4)

Applying the point-slope formula of the straight line,

y - k = m(x - h), where (h, k) is the point, we get:

y - 4 = -2(x - 6), or

y       = 4 - 2x + 12, or      

y   = -2x + 16

Answer:

The general equation is 4x² + 4y² - 8 x + 19 y - 140 = 0

Step-by-step explanation:

* Lets revise the general form of the equation of the circle

- The general form : x² + y² + Dx + Ey + F = 0, where D, E, F are constants

- To find the values of D, E , F we must make three equations contains

  D, E , F and solve them simultaneous

- We can do that if we have three points on the circle to substitute

  x and y in the equation by them

* Now lets solve the problem

- There are three point on the circle (-5 , 0) , (0 , 4) , (2 , 4)

∵ The equation of the circle is x² + y² + Dx + Ey + F = 0

- Lets use the first point

∵ point (-5 , 0) lies on the circle

∴ (-5)² + (0)² + D(-5) + E(0) + F = 0 ⇒ simplify

∴ 25 - 5D + F = 0 ⇒ isolate F

∴ F = 5D - 25 ⇒ (1)

- Lets use the second point

∵ point (0 , 4) lies on the circle

∴ (0)² + (4)² + D(0) + E(4) + F = 0 ⇒ simplify

∴ 16 + 4E + F = 0 ⇒ substitute F form (1)

∴ 16 + 4E + 5D - 25 = 0

∴ 5D + 4E - 9 = 0 ⇒ add 9 to both sides

∴ 5D + 4E = 9 ⇒ (2)

- Lets use the third point

∵ point (2 , 4) lies on the circle

∴ (2)² + (4)² + D(2) + E(4) + F = 0 ⇒ simplify

∴ 4 + 16 + 2D + 4E + F = 0 ⇒ simplify

∴ 20 + 2D + 4E + F = 0 ⇒ substitute F form (1)

∴ 20 + 2D + 4E + 5D - 25 = 0 ⇒ simplify

∴ 7D + 4E - 5 = 0 ⇒ add 5 to both sides

∴ 7D + 4E = 5 ⇒ (3)

- Subtract (3) from (2) to eliminate E

∴ -2D = 4 ⇒ ÷ -2

∴ D = -2

- Substitute the value of D in (3) to find E

∴ 7(-2) + 4E = 5

∴ -14 + 4E = 5 ⇒ add 14 from both sides

∴ 4E = 19 ⇒ ÷ 4

∴ E = 19/4

- Substitute the value of D in (1) to find F

∴ F = 5(-2) - 25

∴ F = -10 - 25 = -35

∴ F = -35

* lets write the equation of the circle

∴ x² + y² - 2x + 19/4 y - 35 = 0 ⇒ × 4

∴ 4x² + 4y² - 8 x + 19 y - 140 = 0

* The general equation is 4x² + 4y² - 8 x + 19 y - 140 = 0
