A student has scores of 66.75, 66, and 72.25 on his first three tests. He needs an average of at least 70 to earn a grade of C. What is the minimum score that the student needs on the fourth test to ensure a C?

Answers

Answer:

75

Step-by-step explanation:

Average needed to get grade C = 70

Average = Total Amount / No of Items.

No of items = 4

therefore Total needed = 70 x 4 = 280

current total score = 66.75 + 66 + 72.25 = 205

the fourth test minimum score = 280 - 205 = 75

can i get some help on that?

Answers

Answer:

p>-6

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

20p+15>−105

Step 2: Subtract 15 from both sides.

20p+15−15>−105−15

20p>−120

Step 3: Divide both sides by 20.

20p/20 > -120/20

p>-6

Answer:

p > -6

Step-by-step explanation:

-5(-4p-3) > -105

First, multiply out the left side to get:

20p+15 > -105

Then take fifteen away from both sides to get:

20p > -120

Then divide both sides by twenty to get:

p > -6

n(ANC) = 14
n(C)= 30

V=

X=

Answers

Answer:

t=14

v=13

q=12

s=23

w=-4

x=28

Step-by-step explanation:

we know that the universal set =100

so, everything in it must add up to 100

first, from the information given to us,

t= n(A n C)= 14

v=n(B n C)= 13

to find q

we know from our guide that n(A) =40

which means everything inside A will add up to 40

therefore,

q + 7 + 7 + t = 40

and we already know that t = 14

so, that will be;

q + 7 + 7 + 14 = 40

therefore, q = 12

to find s,

we all know that n(B) = 50

which means that everything inside B will be equal to 50

therefore,

s + 7 + 7 + v = 50

and we know that v = 13

therefore,

s + 7 + 7 + 13 = 50

and s will end up to be = 23

to find w,

we know that n(C) = 30

so, everything in C end up to be all equal to 30

therefore,

t + 7 + w + v = 30

from our solution, t = 14, v = 13

so,

14 + 7 + w

q = 19, s = 30, t = 7, v = 6, w = 10, x = 7.

What is a set ?

A set is a collection of well defined objects.

According to the given question of Venn diagram given,

n(U) = 100, n(A∩B) = 14, n(A) = 40, n(B∩C) = 13, n(B) = 50, n(A∩C) = 14, n(C) = 30 and n(A∩B∩C) = 7.

t =   n(A∩C) - n(A∩B∩C).

t = 14 - 7

= 7.

q = n(A) - [  n(A∩B) + t ]

q = 40 - ( 14 + 7 )

q = 40 - 21

q = 19.

v = n(B∩C) - n(A∩B∩C)

v = 13 - 7

v = 6.

s =  n(B) - [ n(A∩B) + v ]

s = 50 - ( 14 + 6 )

s = 30.

w =  n(C) - [ n(A∩C) + v ]

w = 30 - ( 14 + 6 )

w = 10.

We know x = n(U) - q - s - w - n(A∩B) - n(B∩C) - n(A∩C) +  n(A∩B∩C).

x = 100 - 19 - 30 - 10 - 14 - 13 - 14 + 7.

x = 7.

B:The growth of a linear function is proportional to the previous growth while the growth of an exponential
function is constant.

C:The growth of a linear function is proportional to the previous growth while the growth of an exponential
function is proportional to the quadratic growth.

D:The growth of an exponential function is proportional to the quadratic growth while the growth of a linear function is constant.

Answers

Answer:

A

Step-by-step explanation:

We know that the growth of a linear function will always be constant. So, that eliminates B and C.

A quadratic function can be a function such as [tex]x^2[/tex], or [tex]5x^2+7x[/tex], etc.

An exponential function wouldn't be [tex]x^2[/tex], it would be [tex]2^x[/tex]! Or [tex]3^x[/tex], or [tex](1.738283)^x[/tex], etc. Therefore, D is eliminated.

So, the answer is [tex]\boxed{A}[/tex] and we're done!

Set the mean and standard deviation to 0 and 5 , respectively. Approximately 5% of the area under the normal curve lies to the right of 8.2 . Consider what would happen if you were to change the mean to 50 and keep the standard deviation at 5 . Can you predict the new value for which approximately 5% of the area under the normal curve lies to the right of this value? Enter your answer accurate to one decimal place.

Answers

Using z-scores and the normal distribution, it is found that the new value would be of 58.2.

In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean.  After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X, which is the area to the left of Z under the normal curve.The area to the right of Z is 1 subtracted by the p-value of Z.

In this problem:

Mean of 50 and standard deviation of 5, thus [tex]\mu = 50, \sigma = 5[/tex].Area to the right of 0.05, thus Z with a p-value of 1 - 0.05 = 0.95, thus [tex]Z = 1.645[/tex].

We have to find the value of X, then:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.645 = \frac{X - 50}{5}[/tex]

[tex]X - 50 = 1.645(5)[/tex]

[tex]X = 58.2[/tex]
