Answer:

We fail to reject the null hypothesis.

Step-by-step explanation:

In a hypothesis test, if the computed p-value is grater than a specified level of significance, then we fail to reject the null hypothesis. The p-value can be computed as the probability of getting a value equal or greater (in absolute value) than the observed value using the test statistic, this implies that if the p-value is greater than a specified level of significance, then the observed value does not fall inside the rejection region. Therefore we fail to reject the null hypothesis.

If (x + 2) is a factor of x3 – 19x – p, find the value of p. Help please

Sergio039 [100]

If $x-a$ is a factor of a polynomial $P(x)$ then, $a$ is its root.

So $-2$ is a root of $x^3-19x-p$

$(-2)^3-19\cdot(-2)-p=0\\-8+38-p=0\\p=30$

Grace [21]

Answer:

Step-by-step explanation:

(f + g)(n) = f(n) + g(n) = n - 3 + n - 2 = 2n - 5 , thus

(f + g)(6) = 2(6) - 5 = 12 - 5 = 7

Ms. Smith purchased ½ of a pound of grapes. She would like to make 112pound portions for this week’s snacks. How many portions w

Elodia [21]

Step-by-step explanation:

There is no enough information to determine how many portions she will be able to make.

We need to know how many pounds of grapes will she needs to make a particular pounds portions for the snacks.

For example, if she needs 2 pounds of grapes to make 5 pounds portion for the snacks, and she purchase ½ pounds of grapes, we can determine how many pounds of portions for the snacks she will be able to make with this information.

Using a simple ratio

2:5 = ½:x

2/5 = ½/x

Multiplying both sides by x

(2/5)x = 1/2

Multiplying both sides by 5/2

x = (1/2)×(5/2)

x = 5/4

x = 1¼ pounds

Meaning she will be able to make 1¼ pounds of portion for snacks with ½ pounds of grapes.
