Answer: 11.29%

Step-by-step explanation:

Given : The sample size : n= 13,000

The number of responses we received = 1,468

Then , the response rate for this survey is given by :-

\hat{p}=\dfrac{\text{\text{Number of response received }}}{\text{Sample size}}\\\\\Rightarrow\ \hat{p}=\dfrac{1468}{13000}=0.112923076923\approx0.1129

In percent , the response rate = 11.29\%

Hence, the response rate = 11.29%

How can you use doubles when multiplying with 4 to find 4x8
pshichka [43]
4 = 2 * 2

Multiplying by 2 is the same a doubling.
Since 4 is 2 * 2, to multiply a number by 4, double the number twice.

Example:
What is 4 * 100?
Double 100 to get 200.
Double 200 to get 400.
Therefore, 4 * 100 = 400.
By doubling twice, we do the same as multiplying by 4.

The function y=40x describes how far from home Shu Ling is as she drives from Dallas to Miami. Graph the function. Use the graph
oksano4ka [1.4K]

Answer:

You can see the graph below.

To answer the question, you need to draw a vertical line from x = 12h up, until the line meets with the line.

Once the line meets with the line, draw a horizontal line from that point, and the value where this line intersects with the y-axis will be the distance from home after 12 hours.

The graph is kinda hard to read because the line is really steep, the green line is the equation y = 40*x

the red line is a line at x = 12

The black dashed line is the horizontal line that intersects with the y-axis.

In the graph, you can see that the dashed line intersects the y-axis at around y = 475.

Then a good estimate is that the distance after 12 hours is 475 (miles).

Now, we can compare this with the direct calculation, just replace x by 12 in the given line:

y = 40*12 = 480.

So our estimation is really accurate.

Can someone please help me find the measure of the exterior angle.
natta225 [31]

Answer:

X=128°

Step-by-step explanation:

Because an exterior angle of a triangle is equal to of the two opposite interior angle.

The sum of the exterior and interior angle is equal to 180°

In this case the part marked red = 90° because is a right angled triangle.

90+38=128

180- 128=52

180- 52=128

x=128.

Factor the expression completely.<br> 3x + 24
Umnica [9.8K]

Answer:

3(x+8)

Step-by-step explanation:

In order to factor the expression completely, you need to find the greatest common factor of both numbers, which would be 3 because 3 fits in both numbers without leading to weird decimals or fractions.

3(x+8) is the answer.
