What is the value of x for that answer?

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

Answer:

D

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

Not another one! ;)

A can be eliminated because the numbers don‘t match. B seems like a possible answer, let’s first check the others out. C and D can be slim instead because the variable, g, should be next to the 1.5 and 2.5. C and D both change the variable location. So, B.

Answer:

the expression is 9)+9(12=21

Step-by-step explanation:

Answer:

commutative property: the property stating that changing the order in which two numbers are added or multiplied does not change the value of the sum or product

Answer:

-44

Step-by-step explanation:

first take -2 to the fifth power (-32) , after that take -2 to the second power (4) and then take -2 to the third power (-8). Subtract -32 and 4, then add -8 and you get your answer.

Answer:

m∠TRI  = 43

Step-by-step explanation:

m∠TRI +  m∠IRB = m∠TRB

3x - 5 + x + 27 = 86

3x + x - 5 + 27 = 86   {Combine like terms}

     4x  + 22    = 86       {Subtract 22 from both sides}

               4x = 86 - 22

                4x = 64           {Divide both sides by 4}

                  x = 64/4

                 x = 16

m∠TRI = 3x - 5

           = 3*16 - 5

          = 48 - 5

          = 43

Answer:

I believe it is 32

Step-by-step explanation:

42÷6+5^2 calculate that and I get 32 I hope this helps.

Answer:

Step-by-step explanation:

first you would need to find the perimeter in order to find the cost of fencing.

x(7x)=1792

7x^2=1792

x^2=256

x=16

so you have x which is the width. now time to find the length

16 times 7 is 112

112 is your width

112+112+16+16 is 256, which is your perimeter.

256 times 1.5 is your cost, or 384 rupees

Answer : 11.80$

Step-by-step explanation:

He spends 8.70$ on Fruit chews and..

4.50 $ on jelly beans

add them up then subtract them by the amount of money he already has

BRAINLIST ???

Answer:

He had 10.85 left

Step-by-step explanation:

Fruit chews 4.7 x 1.6 = 7.52

Jelly beans 2.35 x 2.6 = 6.11

7.52 + 6.11 + 0.52 = 14.15

25 - 14.15 = 10.85

A line has a slope = 2

point = (5,2)

Solution

y-y1=m (x-x1)

Where y1=2,X1=5,m=2

y-2=2(x-5)

Y-2=2x-10

2x-y=-8

Equation of the line is 2x-y=-8

As the opposite of a positive is a negative

Answer:

-3/11

Step-by-step explanation:

Given:

Anna’s cell phone plan charges her $30 per month plus a $150 one-time activation fee.

Evelyn’s cell phone plan charges her $20 per month, plus a $450 one-time activation fee.

To find:

The number of months after which the costs for the girls’ cell phone plans the same.

Solution:

Let x be the number of months.

Total cost = Fixed cost + Variable cost

According to the question, cost equation for Anna’s cell phone is

[tex]y=150+30x[/tex]           ...(i)

Cost equation for Evelyn's cell phone is

[tex]y=450+20x[/tex]         ...(ii)

Equate (i) and (ii) to find the time after which the costs for the girls’ cell phone plans the same.

[tex]150+30x=450+20x[/tex]

[tex]30x-20x=450-150[/tex]

[tex]10x=300[/tex]

Divide both sides by 10.

[tex]x=\dfrac{300}{10}[/tex]

[tex]x=30[/tex]

Therefore, the costs for the girls’ cell phone plans the same after 10 months.

Answer:

v = 3.64 ft/s

Step-by-step explanation:

Given that,

Radius of a carousel, r = 18 feet

It takes 31 seconds to complete revolution.

We need to find the linear speed of the carousel at its outside edge. Distance covered is equal to the circumference of the circle.

d = 2πr

d = 2π × 18 = 113.09 feet

Let v is the linear speed. It can be given by :

[tex]v=\dfrac{D}{t}\\\\v=\dfrac{113.09}{31}\\\\v=3.64\ ft/s[/tex]

So, the linear speed of the carousel is 3.64 ft/s.

Answer:

The duration of the randomly selected class is 52.6 minutes.

Step-by-step explanation:

The random variable X is defined as the duration of a professor's class.

It is provided that, [tex]X\sim Unif(49.2, 55.5)[/tex].

The pdf of X is:

[tex]f_{X}(x)=\frac{1}{55.5-49.2};\ 49.2<X<55.5[/tex]

It is provided that the probability that the duration of the class is longer than c number of minutes is 0.468.

That is, P (X > c) = 0.468.

Compute the value of c as follows:

[tex]P(X>c)=0.468\\\\\int\limits^{55.5}_{c}{\frac{1}{55.5-49.2}}=0.468\\\\\frac{1}{6.3}\times [x]^{55.5}_{c}=0.468\\\\55.5-c=2.9484\\\\x=52.5516\\\\x\approx 52.6[/tex]

Thus, the duration of the randomly selected class is 52.6 minutes.
