Answer:

1: -1\2

2: 2\4 simplified to 1\2

Step-by-step explanation:

for the first one it rises one and runs two that makes it one over two. 1\2 but since it's going down it will be negative one over two

for the second one it rise two and runs four but that's not an option so we simplify it. we divide the top by two and the bottom by two 2÷2=1 4÷2=2

The Graduate Management Admission Test (GMAT) is taken by individuals interested in pursuing graduate management education. GMAT

Answer:

Null hypothesis: \mu_{Phil} \geq 550

Alternative hypothesis: \mu_{Phil} < 550

Step-by-step explanation:

1) Previous concepts

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".  

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".

2) Solution to the problem

Let X the random variable that represent the score for all test‑takers and the distribution for X is:

X \sim N(\mu =550,\sigma=120)

Let \mu_{Phil} the true mean for the Philippines.

On this case we want to test is \mu_{Phil}

So the correct system of hypothesis for this case would be:

Null hypothesis: \mu_{Phil} \geq 550

Alternative hypothesis: \mu_{Phil}< 550

In order to test we know the population deviation and the sample size n=250. But we need the sample mean and a significance level to test the claim.

Answer:

36. m^7

37. x^3 y

38. 6v^5

Step-by-step explanation:

Divide the exponents by the number in the radical sign,

so, If no number is given then divide exponents by 2 eg. question 38

<h3>Explanation </h3>

36. 7√m^49 means m^(49/7) = m^7

37. 3√x^9y^3 means x^(9/3) y^(3/3) = x^3 y

38. √36v^10 means (√36) v^(10/2) = 6v^5 (√36 = 6)
