You would solve this problem by using Pythagorean Theorem. This theorem states a^2+b^2=c^2. C is ALWAYS the hypotenuse. We would have to solve for the smaller triangle first. It would look something like this.
3^2+b^2=5^2
9+b^2=25
b^2=16
b=4
Therefore, the missing side to the small triangle is 4. Now, we can solve for the hypotenuse of the bigger triangle,
4^2+7^2=c^2
16+49=c^2
65=c^2
Side z is approximately equal to 8.

Answer: Pearl

Step-by-step explanation:

In step 2, she justified her step by the definition of vertical angles. However, angles AKL and GKB do not share a common side, meaning they are not adjacent angles.

Answer:

The p-value of the test is of 0.1922 > 0.02, which means that there is not significant evidence to reject the null hypothesis, that is, there is not significant evidence to conclude that the proportion is of less than 40%.

Step-by-step explanation:

Test if the proportion is less than 40%:

At the null hypothesis, we test if the proportion is of at least 0.4, that is:

$H_0: p \geq 0.4$
