Can you help me with #3 please

sveticcg [70]

We have two terms: 3x^3 and -9x

You have the correct GCF which is 3x. This GCF is factored out and placed to the left of the parenthesis, as you have done correctly so far.

Since 3x times x^2 is equal to 3x^3, this means that you have the proper first term inside the parenthesis. So far so good.

Where you make a mistake is with the second term inside the parenthesis. Notice how 3x times 2 is NOT equal to -9x

You need to fill in the blank:
3x times _________ = -9x

It turns out that -3 goes in that blank since 3x times -3 = -9x

This is why the final answer for problem 3 is 3x(x^2 - 3)

Janet bought 3/4 of a pound of apples, 1 1/2 pounds of bananas, and 2 1/4 pounds of grapes. She bought ____ pounds of fruit.

8_murik_8 [283]

Answer:

We have 3/4 plus 3/2 plus 9/4 pounds of fruit, so we get

12/4 + 3/2 pounds of fruit

and 3/2 can become 6/4, so we have 18/4 pounds of fruit, or 4 2/4 pounds, which can simplify into 9/2 or 4 1/2

igor_vitrenko [27]

Answer:

(a) 31101

(b) $5.65

(c) $113.38

Step-by-step explanation:

The complete question is:

A regional automobile dealership sent out fliers to prospective customers indicating that they had already won one of three different prizes: an automobile valued at $20,000, a $125 gas card, or a $5 shopping card. To claim his or her prize, a prospective print on the back of the flier listed the probabilities of winning. The chance of winning the car was 1 out of 31,101, the chance of winning the gas card was 1 out of 31,101, and the chance of winning the shopping card was 31, 099 out of 31,101.

Solution:

The information provided is as follows:

$P(\text{Car})=\frac{1}{31101}\\\\P(\text{Gas Card})=\frac{1}{31101}\\\\P(\text{Shopping Card})=\frac{31099}{31101}$

(a)

The number of fliers the automobile dealership sent out is, <em>n</em> = 31,101.

This is because the probability of winning any of the three prize is out of 31,101.

(b)

Compute the expected value of the prize won by a prospective customer receiving a flier as follows:

$E(X)=\sum x\times P(X=x)$

$=[20000\times \frac{1}{31101}]+[125\times \frac{1}{31101}]+[5\times \frac{31099}{31101}]\\\\=0.6431+0.0040+4.9997\\\\=5.6468\\\\\approx 5.65$

Thus, the expected value of the prize won by a prospective customer receiving a flier is $5.65.

(c)

Compute the standard deviation of the prize won by a prospective customer receiving a flier as follows:

$SD(X)=\sqrt{V(X)}=\sqrt{E(X^{2}-(E(X))^{2}}$

$=\sqrt{[(20000)^{2}\times \frac{1}{31101}+(125)^{2}\times \frac{1}{31101}+(5)^{2}\times \frac{31099}{31101}]-(5.65)^{2}}\\\\=\sqrt{12854.9011}\\\\=113.37947\\\\\approx 113.38$

Thus, the standard deviation of the prize won by a prospective customer receiving a flier is $113.38.
