Answer:

option a

Step-by-step explanation:

as 145 +10 = 155°

and total angle measure of triangle is 180

180-155 = 25°

in option a one angle is 10

other is 25 so obviously last angle will be 145

and same is in the triangle abc

one angle is 10 other is 145 and last is 25

both hve same measures thus are same triangles.

Complete Question

An F5 tornado is classified as having mean wind speeds greater than 261 mph. In an effort to classify a recent tornado, 20 wind speed measurements were randomly selected from within the path of the tornado. Suppose the mean wind speed for this tornado really is greater than 261 mph with a sample standard Deviation 41.09 mph. Based on the data, if we fined little to no evidence against the null hypothesis that the mean wind speed is 261 mph, we have made _______________.

Answer:

$P-value=0.3322$

Step-by-step explanation:

From the question we are told that:

Sample size $n=20$

Population mean $N=261$

Sample mean $\=x= 265.1$

Sample standard deviation $\sigma=41.09$

Generally the equation t test statistics is mathematically given by

$t=\frac{\=x-\mu}{\frac{s}{\sqrt{n} } }$

$t=\frac{265.1-261}{\frac{41.09}{\sqrt{20} } }$

$t=0.446$

Therefore

Pvalue from table is

$P-value=0.3322$

Hello!

As you can see, two of the triangles that we see that are made from the lengths we are given make up one face of the pyramid. We can use the triangle formula without multiplying by 1/2 to find the length of one face.

30(45)=1350

Now we multiply this by four to find all of the sides.

1350(4)=5400

We find the area of the square base

30(30)=900

Finally, we add up our lengths.

5400+900=6300

Therefore, our answer is C) 6400 yards²

I hope this helps!
