Step-by-step explanation:

if it was a rotation, the car would be upside-down in the final product.

if it was a reflection, the car would also be upside-down.

if it was a dilation the final product would be smaller.

This is how we know is a translation.

Answer:

-2

Step-by-step explanation:

This linear equation is in slope-intercept format, aka y=mx+b. This is where m=slope and b=y-intercept. In the following equation, -110 is the slope and -2 replaces b, meaning it is the y-intercept

A sports shop has 84 employees. 25% of the employees work part-time. How many part-time employees does the sports shop have?

Zolol [24]

Answer:

The sports shop has 21 part-time employees.

Step-by-step explanation:

Solution:

What is 25% of 84?

.Y is 25% of 84

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 25% * 84

Converting percent to decimal:

p = 25%/100 = 0.25

Y = 0.25 * 84

Y = 21

Or another quicker way....

50% is half of the whole, and 25 is half of 50.

84/2/2

equals 21 too, I don't recommend to use it as row form.

In 1990, 23.8% of 18-24 year-olds in Biddeford, Maine were attending college. About 10 years later, a random sample of 610 18-24

Vlada [557]

Answer:

There is enough evidence to support the claim that the percentage of residents attending college in that age-group is greater than 23.8%

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 610

p = 23.8% = 0.238

Alpha, α = 0.01

Number of 18-24 year-old attending college , x = 178

First, we design the null and the alternate hypothesis

$H_{0}: p = 0.238\\H_A: p > 0.238$

This is a one-tailed(right) test.

Formula:

$\hat{p} = \dfrac{x}{n} = \dfrac{178}{610} = 0.2918$

$z = \dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

Putting the values, we get,

$z = \displaystyle\frac{0.2918-0.238}{\sqrt{\frac{0.238(1-0.238)}{610}}} = 3.1201$

Now, we calculate the p-value from the table.

P-value = 0.0009

Since the p-value is lower than the significance level, we fail to accept the null hypothesis and reject the null hypothesis.

Conclusion:

Thus there is enough evidence to support the claim that the percentage of residents attending college in that age-group is greater than 23.8%
