Factor completely q^2(p+1)+3(p+1)

2 answers:

7 0

For this case we have the following expression:
q ^ 2 (p + 1) +3 (p + 1)
We observe that the term that is repeated in all the members of the expression is p + 1.
Therefore, by doing common factor we have:
(p + 1) (q ^ 2 + 3)
Answer:
The factored expression is:
(p + 1) (q ^ 2 + 3)

Listed below are the amounts (dollars) it costs for marriage proposal packages at different baseball stadiums. Find the range,

yulyashka [42]

Answer:

Range = 2460 dollars, Variance = 516414.6 $dollars^2$ , Standard deviation = 718.6199 dollars . There are two outliers and they are likely to have much of an effect on the measures of variation.

Step-by-step explanation:

The smallest value in the sample data is min = 50 dollars and the largest value is max = 2500 dollars, therefore, the range is Range = max - min = 2500 - 40 = 2460 dollars. On the other hand, the formula to compute the sample variance is $S^2 = \frac{1}{n-1}\sum_{i=1}^{n} (x_{i}-\bar{x})^2$ where $\bar{x}$ is the sample mean, n is the sample size and the $x_{i}$ are the sample values. In this case the sample variance is $s^2$ = 516414.6 $dollars^2$ , the sample standard deviation is defined as the squared root of the sample variance, so, the sample standard deviation is s = 718.6199 dollars. There are two outliers because 1750 dollars and 2500 dollars are very different compared to the other values, these two numbers are very large and they are likely to have much of an effect on the measures of variation because these measures are sensible to outliers, they are no robust measures.

Juno ams Akima are training for a blathlon together. They are going to jog for the same amount of time as each other every day w

alexgriva [62]

Answer:3 hours

Step-by-step explanation:

Juno jogs at rate of 6 miles and bikes at rate of 14 miles covering total of 48 miles.

Akima jogs at rate of 8 miles and bikes at rate of 12 miles covering total of 44 miles.

Let jogging be represented by j

Let biking be represented by b

For Juno, 6j + 14b = 48 ......... i

For Akima, 8j + 12b = 44.......... ii

Multiply equation I by 8

Multiply equation ii by 6

48j + 112b = 384 ........... iii

48j + 72b = 264 ............. iv

Subtract equation iv from iii

48j + 112b = 384

- 48j + 72b = 264

40b = 120

b = 120/40

b = 3

Number of hours spent biking is 3 hours.

How many ounces are equivalent to 6 pounds?

Dima020 [189]

Answer:

Step-by-step explanation:

1 pound is 16 ounces

6 pounds=x ounces

So we use the X to signal it's presence

1x16 is 16,

That means 16 ounces

6xP=Q

6x16 will give us our answer

Because it will tell us how many pounds there are since ounces is multiplied to get ounces.

6x16=96

P=16

Q=96

96 is our answer.

I hope this helps!!!!
