Answer:

100 degrees

Step-by-step explanation:

at first i thought it was a right angle but i looked at the other shape and seen it was a 80 degree angle for B, then i seen C on the same shape, so that just proved what i thought that W was on the other shape because its not a 90 degree right angle, its a bigger angle not as big as C on the other shape, but not a 90 degree angle either, so its 100 degree angle.

The high temperature Monday was 4 degrees. The low temperature was -7 degrees. What is the difference between the high and low t

OleMash [197]

Answer:

Hey there!

We are trying to find the difference between 4 and -7

We can write -7+x=4, where x is the difference we are trying to find.

Solving for x, we get that the difference is 11.

Let me know if this helps :)

A hospital claims that the proportion, p, of full-term babies born in their hospital that weigh more than 7 pounds is 36%. In a

Answer:

Claim :The proportion, p, of full-term babies born in their hospital that weigh more than 7 pounds is 36%.

n = 170

x = 56

We will use one sample proportion test

$\widehat{p}=\frac{x}{n}$

$\widehat{p}=\frac{56}{170}$

$\widehat{p}=0.3294$

The proportion, p, of full-term babies born in their hospital that weigh more than 7 pounds is 36%.

$H_0:p \neq 0.36 \\H_a:p= 0.36$

Formula of test statistic = $\frac{\widehat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}$

$=\frac{0.3294-0.36}{\sqrt{\frac{0.36(1-0.36)}{170}}}$

=−0.8311

Now refer the p value from the z table

P-Value is .202987 (Calculated by online calculator)

Level of significance α = 0.05

Since p value < α

So we reject the null hypothesis .

Hence the claim is true
