Mathematics

If two shapes are congruent, then the corresponding angles/sides are the same.

We are given the triangle DEF and WXY. This means that both triangles are congruent.

The sides are named after letters and they are placed in the same order in the congruence statement:

∠D ≅ ∠W

∠E ≅ ∠X

∠F ≅ ∠Y

These angles are the same:

DF ≅ WY

EF ≅ XY

DE ≅ WX

Therefore, the answer is [ ∠E ≅ ∠X; DF ≅ WY ]

Best of Luck

Answer:

14.7

Step-by-step explanation:

a^2+b^2=c^2

15^2+b^2=21^2

225+b^2=441

subtract 441-225=216

square root of 216 = 14.6969384567

Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.9 years with a
Bas_tet [7]

Answer:

5.9 years.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

In this question:

Mean of the population is \mu = 5.9

If a sampling distribution is created using samples of the ages at which 69 children begin reading, what would be the mean of the sampling distribution of sample means?

By the Central Limit Theorem, the same population mean, of 5.9 years.
