Brown tree snakes are an invasive species causing huge environmental and financial damage in Guam. Researchers captured brown tr
storchak [24]

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.

<u><em>Let </em></u>\mu<u><em> = mean weight of a brown tree snake in Guam.</em></u>

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

Alternate Hypothesis, H_A : \mu > 120 grams

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

On the other hand, <u>alternate hypothesis states that</u> 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.

Use the square root method to find the solutions to the quadratic equation 22
lakkis [162]

Answer:

x = 2\sqrt{2}, -2\sqrt{2}

Step-by-step explanation:

Given

x^2 - 8 = 0

Required

Solve

We have:

x^2 - 8 = 0

Add 8 to both sides

x^2 = 8

Take square roots of both sides

x = \±\sqrt{8}

Expand

x = \±\sqrt{4*2}

This gives:

x = \±2\sqrt{2}

Split

x = 2\sqrt{2}, -2\sqrt{2}

A sports team came to town. the stadium filled all 10,000 seats at two-level pricing. level 1 tickets are $50 each, and level 2
marissa [1.9K]

x represents the number of tickets of level 1 and y represents the number of tickets of level 2 in the system given that there are 10,000 seats, level 1 tickets are $50 each, and level 2 tickets are $150 each and equation representing the situation:x + y = 10,000, 50x + 150y = 75,000. This can be obtained by understanding the question and observing the equations.

<h3>What do the x and y represent in the system?</h3>

Given that total number of seats is 10,000 and there are two levels pricing.

Thus by observing the equation, x + y = 10,000,

10,000 is the sum of 2 variable which obviously will be the number of tickets in level 1 and number of tickets in level 2.

Since there are two level pricing,

50x + 150y = 75,000 represent the addition of total cost of tickets of level 1 and 2.

Hence x represents the number of tickets of level 1 and y represents the number of tickets of level 2 in the system given that there are 10,000 seats, level 1 tickets are $50 each, and level 2 tickets are $150 each and equation representing the situation:x + y = 10,000, 50x + 150y = 75,000.
