Find the standard deviation of the distribution in the following situations. (Round your answers to two decimal places.) (a) MEN

Arturiano [62]

Answer:

a) 15.579

b) 39.019

Step-by-step explanation:

a) For the top 2% the z-value from the z table

z = 2.054

thus,

z = $\frac{\textup{X-Mean}}{\sigma}$

here

X = 132

Mean = 100

thus,

2.054 = $\frac{\textup{132-100}}{\sigma}$

σ = 15.579

b) Using tables, we get for Z = 0.89 the value of 0.8133 and for Z= 0.90 the value of 0.8159

By interpolation, values for 0.815 and we get Z=0.897

thus,

z = $\frac{\textup{X-Mean}}{\sigma}$

here

X = 220

Mean = 185

thus,

0.897 = $\frac{\textup{220-185}}{\sigma}$

σ = 39.019

A 14- inch pepperoni pizza is sliced into 8 equal pieces. One slice contained 352 calories. Write and solve a division equation

tankabanditka [31]

Division equation is:

$\frac{c}{8} = 352$

There are 2816 calories in whole pizza

Solution:

Given that,

A 14- inch pepperoni pizza is sliced into 8 equal pieces

One slice contained 352 calories

Therefore,

1 slice = 352 calories

Let "c" be the calories

Given that there are 8 equal pieces

Therefore, calories in 8 pieces are:

Calories in 8 pieces = 8 x calories in 1 piece

$c = 8 \times 352$

Thus the division equation is:

$\frac{c}{8} = 352$

Therefore,

$c = 352 \times 8 = 2816$

Thus there are 2816 calories in whole pizza

Mrs. Eaton's class is participating in the "Box Tops for Education" campaign. On the first day, her

storchak [24]

Each colection day: D
Number of tops collected on that day: N

D1=1; N1=2
D2=3; N2=8

1) Linear model
N-N1=m(D-D1)

m=(N2-N1)/(D2-D1)
m=(8-2)/(3-1)
m=(6)/(2)
m=3

N-N1=m(D-D1)
N-2=3(D-1)
N-2=3D-3
N-2+2=3D-3+2
N=3D-1

when D=6:
N=3(6)-1
N=18-1
N=17

What is the number of tops collected on the sixth day based on the linear model?
The number of tops collected on the sixth day based on the linear model is 17.

2) Exponential model
N=a(b)^D
D=D1=1→N=N1=2→2=a(b)^1→2=ab→ab=2 (1)

D=D2=3→N=N2=8→8=a(b)^3→8=a(b)^(1+2)
8=a(b)^1(b)^2→8=ab(b)^2 (2)

Replacing (1) in (2)
(2) 8=2(b)^2
Solving for b:
8/2=2(b)^2/2
4=(b)^2
sqrt(4)=sqrt( b)^2 )
2=b
b=2

Replacing b=2 in (1)
(1) ab=2
a(2)=2
Solving for a:
a(2)/2=2/2
a=1

Then, the exponential model is N=1(2)^D
N=(2)^D

When D=6:
N=(2)^6
N=64

What is the number of tops collected on the sixth day based on the exponential model?
The number of tops collected on the sixth day based on the exponential model is 64

Help Please! I'm having such a hard time :(

RUDIKE [14]

Answer:

It should cost $3.50.

Step-by-step explanation:

Because 5 is 40% Greater than 3, and 40% of 2.50 is 1, then just add 2.50 and 1 and you have your answer. $3.50
