Answer:

CV of Bank A = 6.4

CV of Bank B = 7.1

CV of Bank B is more than CV of Bank A

Step-by-step explanation:

Bank A

6.6, 6.7, 6.7, 6.8, 7.0, 7.3, 7.5, 7.7, 7.8, 7.8

[tex]Mean = \frac{\text{Sum of all observations}}{\text{No. of observations}}\\Mean = \frac{6.6+6.7+6.7+6.8+7.0+7.3+7.5+7.7+7.8+ 7.8}{10}\\Mean =7.19[/tex]

Standard deviation =[tex]\sqrt{ \frac{\sum(x-\bar{x})^2}{n}}=0.461[/tex]

[tex]CV = \frac{\sigma}{\bar{x}} \times 100\\CV = \frac{0.461}{7.19} \times 100=6.4[/tex]

Bank B

4.0, 5.5, 5.8, 6.2, 6.6, 7.6, 7.7, 8.5, 9.4, 9.7

[tex]Mean = \frac{\text{Sum of all observations}}{\text{No. of observations}}\\Mean = \frac{4.0+5.5+5.8+6.2+6.6+ 7.6+ 7.7+8.5+9.4+9.7}{10}\\Mean =7.1[/tex]

Standard deviation =[tex]\sqrt{ \frac{\sum(x-\bar{x})^2}{n}}=1.718[/tex]

[tex]CV = \frac{\sigma}{\bar{x}} \times 100\\CV = \frac{1.718}{7.1} \times 100=24.2[/tex]

CV of Bank A = 6.4

CV of Bank B = 7.1

CV of Bank B is more than CV of Bank A

0.75 * 10^5 is not in scientific notation since the base 0.75 is smaller than 1.

The general format for scientific notation is b*10^n where b is the base and n is the exponent

If the base b is positive, then it must fit the criteria that [tex]1 \le b < 10[/tex]. So b = 1 is the smallest it can get

Here's how to convert it to scientific notation

0.75 * 10^5

(7.5 * 10^(-1)) * 10^5

7.5 * (10^(-1)*10^5)

7.5 * 10^(-1+5)

7.5 * 10^4

The number is now in scientific notation since b = 7.5 fits the interval [tex]1 \le b < 10[/tex]

I think the slope is 1. hope that helps

Answer:

the answer is to your question is -2.7 :)

Answer:

5

Step-by-step explanation:

Answer:

18

Step-by-step explanation:

When you scale down you divide. it showed that 9 = 3. to go from 9 to 3 you divide by 3. So you have to do the same thing for the other number. So, 18 divided by 3, which is 6.

When you scale up you multiply. it showed that 18 = 36. To get from 18 to 36 you multiply by 2. So, you do the same thing to the other number, 9 times 2, which is 18.

Answer:

there will be 39 students in the school but not sure how to put it in partial quotients

Answer:

Ok, So....

Step-by-step explanation:

Since m3=74 that must mean that m4 and m1 are 74 because they are vertical angles. and since m2 is a vertical angle of m1 it is also 74. Then you have m8 m6 m7 m5 which are suplementary to them meaning they sum to 180 and since m3+m8=180, 74+m8=180. m8=180-74.

m8=m7=m6=m5= 106

I hope this helped!

The point where two lines meet is known as an angle.

From the diagram shown, we can see that l is parallel to m

Given

Based on geometry:

m<3 = m<4 = 74 degrees (vertically opposite)

m<3 = m<1 = 74 degrees (corresponding angles)

m<1 = m<2 = 74degrees (vertically opposite angles)

m<1 and <6 are supplementary, that is:

m<1 + m<6 = 180

74 + m<6 = 180

m<6 = 180 - 74

m<6 = 106degrees

Similarly:

m<2 and <5 are supplementary, that is:

m<2 + m<5 = 180

74 + m<5 = 180

m<5 = 180 - 74

m<5 = 106degrees

Also, m<4 and <7 are supplementary, that is:

m<4 + m<7 = 180

74 + m<7 = 180

m<7 = 180 - 74

m<7 = 106degrees

m<7 = m<8 = 108 degrees (vertically opposite angles)

Answer:

the son is 2

man is 26

+10 yrs

son=12

man=36

Step-by-step explanation:

Let the son's age be x.

Then the father's age is 13x.

In ten years their ages will be (x+10) and (13x+10).

(13x+10)=3(x+10)

13x+10=3x+30

10x=20

x=2

The son is 2 years old.

Answer:

a) 25 in.

b) 13 in.

c) 4 in.

d) 61 in.

e) 30 weeks

Step-by-step explanation:

For a, b, c, and d, the equation to use is y = 3x + 4 and just plug in the given values for x (weeks) to receive y (inches of vine)

for e, use the same equation, but plug in 94 for y...

94 = 3x + 4    →   3x = 90    →    x = 30

Answer:

Grace weighed 167 pounds before she started her exercise program.

Step-by-step explanation:

Given,

Weight lost by Grace = 45 pounds

Weight of Grace after exercise weeks = 122 pounds

Let,

x represents the weight of Grace before she started the exercise program.

Loss means subtraction, therefore,

We will subtract the lost weight from original weight.

Original weight - Weight lost = Weight after exercise weeks

[tex]x - 45 = 122[/tex]

Adding 45 on both sides

[tex]x - 45+ 45= 122+45[/tex]

[tex]x=167 pounds[/tex]

Grace weighed 167 pounds before she started her exercise program.

Answer:

Factors and multiples are different things.

But they both involve multiplication:

Factors are what we can multiply to get the number

Multiples are what we get after multiplying the number by an integer (not a fraction).

Example: the positive factors, and some multiples, of 6:

factors of 6: ..., 1, 2, 3, 6; multiples of 6: ... 0, 6, 12, 18, ...

Factors:

1 × 6 = 6, so 1 and 6 are factors of 6

2 × 3 = 6, so 2 and 3 are factors of 6

Multiples:

0 × 6 = 0, so 0 is a multiple of 6

1 × 6 = 6, so 6 is a multiple of 6

2 × 6 = 12, so 12 is a multiple of 6

and so on

(Note: there are negative factors and multiples as well)

Here are the details:

Factors

"Factors" are the numbers we can multiply together to get another number:

in 2x3=6, 2 and 3 are factors

2 and 3 are factors of 6

A number can have many factors.

Example: 12

3 × 4 = 12, so 3 and 4 are factors of 12

Also 2 × 6 = 12, so 2 and 6 are also factors of 12,

And 1 × 12 = 12, so 1 and 12 are factors of 12 as well.

AND because multiplying negatives makes a positive, −1, −2, −3, −4, −6 and −12 are also factors of 12:

(−1) × (−12) = 12

(−2) × (−6) = 12

(−3) × (−4) = 12

So ALL the factors of 12 are:

1, 2, 3, 4, 6 and 12

AND −1, −2, −3, −4, −6 and −12

Multiples

A multiple is the result of multiplying a number by an integer (not a fraction).

Example: Multiples of 3:

Multiples of 3: ..., −9, −6, −3, 0, 3, 6, 9, ...

..., −9, −6, −3, 0, 3, 6, 9, ...

Example: 15 is a multiple of 3, as 3 × 5 = 15

Example: 16 is not a multiple of 3

Example: Multiples of 5:

Multiples of 5: ..., −15, −10, −5, 0, 5, 10, 15, ...

..., −15, −10, −5, 0, 5, 10, 15, ...

Example: 10 is a multiple of 5, as 5 × 2 = 10

Example: 11 is not a multiple of 5

Multiples of Anything

We must multiply by an integer, but the number that is being multiplied can be anything.

Example: Multiples of π

..., −2π, −π, 0, π, 2π, 3π, 4π, ...
