Define the formula for the surface area of a square pyramid.
 A square pyramid has a square base and four triangular sides.
 The formula for this case is:
 A = s ^ 2 + 2 * s * L
 Where,
 s: side of the base
 L: inclined height
 The inclined height is:
 L = root (h ^ 2 + (s / 2) ^ 2)
 Where,
 L = root (12 ^ 2 + (12/2) ^ 2)
 L = root (144 + 36)
 L = root (180)
 L = 13.42
 Substituting values:
 A = (12) ^ 2 + 2 * (12) * (13.42)
 A = 466.08 in ^ 2
 Answer:
 
The surface area is:
 
A = 466.08 in ^ 2

7w−(2+w)=2(3w−1)
Llana [10]
Simplify brackets

(7w - 2 - w = 2(3w - 1)

simplify 7w - 2 - w to 6w - 2

(6w - 2 = 2(3w - 1)

Expand

(6w - 2 = 6w - 2)

Since both sides are equal, there are infinitely many solutions

Answer: C) INFINITELY MANY

A university administrator was interested in determining if there was a difference in the distance students travel to get from c
eduard

Answer:

1) Fail to reject the Null hypothesis

2) We do not have sufficient evidence to support the claim that the mean distance students traveled to school from their current residence was different for males and females.

Step-by-step explanation:

A university administrator wants to test if there is a difference between the distance men and women travel to class from their current residence. So, the hypothesis would be:

H_{o}: \mu_{F}-\mu_{M}=0\\\\ H_{a}: \mu_{F}-\mu_{M}\neq 0

The results of his tests are:

t-value = -1.05

p-value = 0.305

Degrees of freedom = df = 21

Based on this data we need to draw a conclusion about test. The significance level is not given, but the normally used levels of significance are 0.001, 0.005, 0.01 and 0.05

The rule of the thumb is:

  • If p-value is equal to or less than the significance level, then we reject the null hypothesis
  • If p-value is greater than the significance level, we fail to reject the null hypothesis.

No matter which significance level is used from the above mentioned significance levels, p-value will always be larger than it. Therefore, we fail to reject the null hypothesis.

Conclusion:

We do not have sufficient evidence to support the claim that the mean distance students traveled to school from their current residence was different for males and females.
