IA triangular parking lot is paved outside a new shopping center. The lengths of the sides of the parking lot are 100 meters, 11

Gemiola [76]

Answer:

Step-by-step explanation:

I believe the only way to solve this is by Heron's Formula.

Add up all the sides and divide by 2 to get the semi-perimeter:

113+100+86 = 299

299/2 = 149.5

Now fill in the rest, which looks like this:

$\sqrt{s(s-a)(s-b)(s-c)}$

where s is your semiperimeter value, a is the length of one side, b the length of another side, and c the length of the third side:

$\sqrt{149.5(149.5-113)(149.5-100)(149.5-86)}$

which simplifies to

$\sqrt{149.5(36.5)(49.5)(63.5)}$

which simplifies further to

$\sqrt{17151929.44}$

which, on your calculator, is 4141.49 meters squared (that's rounded to the nearest hundredth).

madam [21]

Answer:

(A) We failed to reject the null hypothesis

Step-by-step explanation:

Given that a high school teacher hypothesized that in her class, boys were taller than girls. If the probability value of her null hypothesis is 0.34, it means:

Here p value is 0.34

This is greater than 0.05 or 0.1 i.e. both for 5% significance and 10% significance.

Whenever p > alpha, we fail to reject null hypothesis

A) We failed to reject the null hypothesis

This would be the correct option

i.e. final conclusion is that there is no significant difference between mean height of girls and mean height of boys at 5% or 10% significance level.
