**Answer: Yes, it is a solution**

**Step-by-step explanation:**

So in the parenthesis, 4 is x and 5 is y, since x comes before the y. Plug the 4 in where the x is, and the 5 where the y is, and you should get 5= 12-7. 12-7 does equal 5, therefore it is a solution :)

Question

60 randomly selected students were asked how many siblings were in their family. Let X = the number of pairs of siblings in the student's family. The results are as follows: Siblings1 2 3 4 5 6 7 Frequency 13 22 15 6 3 0 1 Round your answers to two decimal places. The mean is: The median is: The sample standard deviation is: The first quartile is: The third quartile is: What percent of the respondents have had less than 3 siblings? % 20% of all respondents have had at most how many siblings?

Solution 1

**Answer:**

**Step-by-step explanation:**

From the information on 60 students we write frequency distribution as

x Â Â Â 1 Â Â Â Â 2 Â Â Â Â 3 Â Â Â Â 4 Â Â Â Â Â 5 Â Â Â Â Â Â 6 Â Â 7 Â Â total

f Â Â Â Â 13 Â Â Â 22 Â Â Â 15 Â Â Â Â 6 Â Â Â Â Â 3 Â Â Â Â Â Â 0 Â Â 1 Â Â Â 60

C Â Â Â 13 Â Â Â 35 Â Â Â 50 Â Â 56 Â Â Â 59 Â Â Â Â Â 59 Â Â 60

xf Â Â Â 13 Â Â Â 44 Â Â 45 Â Â Â 24 Â Â Â Â 15 Â Â Â Â Â Â 0 Â Â 7 Â Â Â 148

x^2f Â 13 Â Â Â 88 Â Â 135 Â Â 96 Â Â Â 75 Â Â Â Â Â Â 0 Â 49 Â Â Â 456

Mean = 2.67

Var = 445.92

Std dev = 21.21

I quartile = 2

III quartile = 3

20% have atmost 1

Question

In training for an Olympic bike race, Ped Al Moore trained by riding 216 miles in 12 hours, for an average of 18 miles per hour. Using this information, which inverse variation could you use to determine his speed if he covers the 216 miles in different amounts of time?

Solution 1

**Answer:**

**Step-by-step explanation:**

In training for an Olympic bike race, Ped Al Moore trained by riding 216 miles in 12 hours, for an average of 18 miles per hour.

Speed is inversely proportional to the time taken

speed is 18 miles per hour and distance is 216 miles

Let 's' be the speed and 't' be the different time

Replace distance by 216

Question

Dions grandmother is making a quilt using for small squares put together to form one large Square block how many different blocks can she make using one each of red green blue and yellow small squares show the possible arrangement

Solution 1

**Answer:**

4! = Â 24.

**Step-by-step explanation:**

Each square can be replaced by one another to make an unique combination.

For example

The First square is red and second one is blue, and green and yellow respectively. All these squares can change position with eachother.

Which make it 24 Possibilities in total.

Question

Quality Cleaners decides to raise the price of dry cleaning a vest from $5 to $6. The same percent increase is applied to dry cleaning a dress. The old cost of dry cleaning a dress is $12. What is the new cost of dry cleaning a dress?

Solution 1

**Answer:**

$14.4

**Step-by-step explanation:**

The original price of dry cleaning a vest = $5

The new price of dry cleaning a vest = $6

The percentage increase is obtained by

Ã— 100

Ã—100 = 20%

hence, there is a 20% increase in price.

applying this 20% increase to the cost of dry cleaning, the new cost will become

Ã—12

this is a 120% increase in cost.

mathematically this can be solved by

Ã—12 = $14.4

hence, the new cost of dry cleaning is $14.4

Question

(1 point) Find f if F"(x) = sin 2 + cos x, f(0) = 10, and f(0) = 7.

Solution 1

**Answer:**

F(x)=sin(2)*-cos(x) +10x + 8

**Step-by-step explanation:**

in order to find F(x) you need to integrate two times.

-> First time

F'(x) = sin(2)*x + sin(x) + C,

if F'(0)=10 then F'(0)=sin(2)*(0) +sin(0) +c=10, so c=10.

Replacing C=10

F'(x) = sin(2)*x + sin(x) + 10.

-> Second time

F(x)=sin(2)*-cos(x) +10x +

if F(0) = 7 then sin(2)*0 - cos(0) + 10*0 +=7

so =8

Replacing this

F(x)=sin(2)*-cos(x) +10x + 8

If f(0)=10 and f'(0)=7 the answer is F(x)=sin(2)*-cos(x) +7x + 11

if F''(x)=sin(2x)+cos(x), f(0)=10, f'(0)=7 , the answer is F(x)=-sin(2x)/4 -cos(x) +15x/2+11
