Answer:

Scale Factor states that the ratio that you get when you divide corresponding side lengths of similar figures.

Given: Triangle ABC is congruent to Triangle DEF.

Similar figures have corresponding angles that are equal and corresponding sides that are equal.

To find the scale factor,

you need to find the ratio between the corresponding sides of the triangle.

now, you can multiply each side of one triangle by the same number to get the sides of the other triangle.

∴ The number is the scale factor, that is what we are trying to find.

shutvik [7]

Answer:

d<3

Step-by-step explanation:

-7d+8>29

First lets remove the inequality for know

-7d+8=29

then remember to re add the inequality to the equation

-7d>21

since you divide by negative you switch

d<3

that is your answer

The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the e

marusya05 [52]

Answer:

The estimation for the proportion of tenth graders reading at or below the eighth grade level is given by:

$\hat p =\frac{955-812}{955}= 0.150$

$0.150 - 1.64 \sqrt{\frac{0.150(1-0.150)}{955}}=0.131$

$0.150 + 1.64 \sqrt{\frac{0.150(1-0.150)}{955}}=0.169$

And the 90% confidence interval would be given (0.131;0.169).

Step-by-step explanation:

We have the following info given:

$n= 955$ represent the sampel size slected

$x = 812$ number of students who read above the eighth grade level

The estimation for the proportion of tenth graders reading at or below the eighth grade level is given by:

$\hat p =\frac{955-812}{955}= 0.150$

The confidence interval for the proportion would be given by this formula

$\hat p \pm z_{\alpha/2} \sqrt{\frac{\hat p(1-\hat p)}{n}}$

For the 90% confidence interval the significance is $\alpha=1-0.9=0.1$ and $\alpha/2=0.05$ , with that value we can find the quantile required for the interval in the normal standard distribution and we got.

$z_{\alpha/2}=1.64$

And replacing into the confidence interval formula we got:

$0.150 - 1.64 \sqrt{\frac{0.150(1-0.150)}{955}}=0.131$

$0.150 + 1.64 \sqrt{\frac{0.150(1-0.150)}{955}}=0.169$

And the 90% confidence interval would be given (0.131;0.169).

Talia has a daily budget of $94 for a car rental. Write and solve an inequality to find the greatest distance Talia can drive ea

MariettaO [177]

Answer:

Step-by-step explanation:

Distance traveled by Talia = x

Cost for travelling 'x' miles = x * 0.20 = 0.2x

Daily budget = $94

Inequality,

30 + 0.2x ≤ 94

Solution:

0.2x ≤ 94 - 30

0.2x ≤ 64 {Divide both sides by 0.2

x ≤ 64/0.2

x ≤ 320
