Answer:

The scale factor is 0.25

Step-by-step explanation:

we know that

The dilation is a non-rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

ABCD and A'B'C'D' are similar

therefore

\frac{A'B'}{AB}=\frac{B'C'}{BC}=\frac{C'D'}{CD}=\frac{A'D'}{AD}

Find the scale factor

Looking at the graph

we have

A'B'=1\ unit\\AB=4\ units

Let

z ---> the scale factor

z=\frac{A'B'}{AB}

substitute the values

z=\frac{1'}{4}=0.25

Keelah's clothing store bicycles for $50 and then sells them for $80 what is the percent of markup on the price of the coat
kondaur [170]

Answer:

62.5%

Step-by-step explanation:

We can write a proportion. We know that $50 is the original value and $80 is the marked up price. We don't know the marked up percentage. Let's call it x. We write equal ratios of \frac{x}{100} comparing percent and \frac{50}{80} comparing the 50 to the marked up price. We then set them equal.

\frac{x}{100} =\frac{50}{80}

We then cross multiply across the equal sign from numerator to the opposite numerator.

80(x)=50(100)

80x=5000

We divide to find x.

x=62.5

This means the bicycles are marked up 62.5% and the original value is 37.5%.

Suppose that the quality control manager for a cereal manufacturer wants to ensure that bags of cereal are being filled correctl
likoan [24]

Answer: No, these results are not statistically significant because

p > 0.05

Step-by-step explanation:

The null hypothesis is

H0 : μ = 17

The alternative hypothesis is

H 1 : μ ≠ 17

where μ is the mean amount of cereal in each box.

The p value that he got is 0.1499. This is greater than alpha = 0.05 which is the given level of significance.

If the level of significance is lesser than the p value, we would accept the null hypothesis.

Therefore, the correct option is

No, these results are not statistically significant because p>0.05
