Answer:

16y - 4

Step-by-step explanation:

4y(4y - 4) - 4(- 4 + 5 + 4y^2)

16y - 16y - 4(1 + 4y^2)

16y - 16y - 4(4y^2 + 1)

16y^2 - 16y^2 + 4

Answer:

Null Hypothesis, $H_0$ : $\mu$ $\leq$ 120 grams

Alternate Hypothesis, $H_A$ : $\mu$ > 120 grams

Step-by-step explanation:

We are given that researchers captured brown tree snakes on Guam's Andersen Air Force Base, and a random sample of 250 of these snakes were weighed.

The researchers want to perform a hypothesis test to see if the mean weight of a brown tree snake in Guam is significantly greater than 120 grams.

Let $\mu$ = mean weight of a brown tree snake in Guam.

So, Null Hypothesis, $H_0$ : $\mu$ $\leq$ 120 grams

Alternate Hypothesis, $H_A$ : $\mu$ > 120 grams

Here, null hypothesis states that the mean weight of a brown tree snake in Guam is smaller than or equal to 120 grams.

On the other hand, alternate hypothesis states that the mean weight of a brown tree snake in Guam is significantly greater than 120 grams.

So, this would be the appropriate null and the alternative hypothesis to test this claim.

Masteriza [31]

Answer:

(x + 5)^2 = (5 - 3)^2

Step-by-step explanation:

Given the equation;

x^2 + 10x + 22 = 13

We have;

x^2 + 10x = 13 - 22

x^2 + 10x = -9

Adding half of 10 to both sides and completing the square as usual, we have;

(x + 5)^2 = 5^2 + (-9)

(x + 5)^2 = (5 - 3)^2
