An equation is a mathematical sentence that contains an equal sign.

To understand this further, I'll show an example.

Suppose that we had a balance and a bunch of blocks for reference. If we put the bag on one side of the balance and put a number of blocks on the other side of the balance, they even out. If the number of blocks on the right side of the balance is 8, this means that the number of blocks in the bag is 8. We can write this as X = 8.

X = 8 is an example of an equation since it's a mathematical sentence that has an equal sign in it.

Answer:

the second one 9v+36

Step-by-step explanation:

because with the way it set up it wants you to multiply 9 by everything inside of the parenthesis so 9 times v is 9v and 9 times 4 is 36 thus 9v+36 and you also take the addition symbol from inside the parenthesis.

Answer:

Step-by-step explanation:

We would set up the hypothesis test.

For the null hypothesis,

µ ≥ 3.5

For the alternative hypothesis,

µ < 3.5

It is a left tailed test.

Since the population standard deviation is given, z score would be determined from the normal distribution table. The formula is

z = (x - µ)/(σ/√n)

Where

x = sample mean

µ = population mean

σ = population standard deviation

n = number of samples

From the information given,

µ = 3.5

x = 3.6

σ = 0.4

n = 36

z = (3.6 - 3.5)/(0.4/√36) = 1.5

Looking at the normal distribution table, the probability corresponding to the z score is 0.933

The p value gotten is to the right of the normal curve. Since it is a left tailed test, we need the p value to the left of the curve. Therefore,

p = 1 - 0.933 = 0.067

Since alpha, 0.05 < than the p value, 0.067, then we would fail to reject the null hypothesis. Therefore, At a 5% level of significance, there is no significant evidence that mean GPA of these graduates does not exceed 3.50
