salaries of nurses in southern california are normally distributed with a mean of $6250 and a standard deviation of $250. what is the probability the mean salary of 25 randomly selected nurses is below $6150 or is above $6350 a month

Answers

Answer 1

Step-by-step explanation:

z-score of X = 6150

[tex] \frac{6150 - 6250}{250} = - 0.4 \\[/tex]

z-score of X = 6350

[tex] \frac{6350 - 6250}{250} = - 0.4[/tex]

P(X<6150) + P(X>6350)

=P(z<-0.4) + P(z>-0.4)

=0.3446+0.3446

=0.6892

Evaluate f(x)=2x+8 when x=−2, x=0, and x=5.

Answers

f ^− 1 ( x )  =  x/2  − 4

That is the inverse

The value of the function, for x=-2 is 4.

The given function is f(x)=2x+8.

What is the function?

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

When x=-2, we get

f(-2)=2(-2)+8

=4

When x=0, we get

f(0)=2(0)+8

= 8

When x=5, we get

f(5)=2(5)+8

= 18

Therefore, the value of the function, for x=-2 is 4.

1) In how many ways can a girl choose a two-piece outfit from 9 blouses and 8 skirts?
A) 17
B) 19
C) 144
D) 72

Answers

D. There are 9 blouse options and 8 skirt options. So, for each of the 9 blouses, there are 8 skirt options. Multiply 9x8, which equals 72

The total number of ways a girl can choose a two-piece outfit from 9 blouses and 8 skirts is 72.

What is permutation?

Permutation is a mathematical calculation of the number of ways a particular set can be arranged, where order of the arrangement matters.

Permutation Formula

[tex]^{n} P_{r} = \frac{P!}{(n-r)!}[/tex]

Where,

[tex]^{n}P_{r}[/tex] is permutation

n is the number of objects

r is the number of objects selected.

According to the given question.

Total number of blouses = 9

Total number of skirts = 8

So,

the number of ways of choosing one blouse from 8

=[tex]^{8} P_{1}[/tex]

= [tex]\frac{8!}{(8-1)!} \\[/tex]

= [tex]\frac{8!}{7!}[/tex]

= [tex]\frac{8\times 7!}{7!}[/tex]

= [tex]8[/tex]

And the number of ways of choosing one skirt from 9

[tex]^{9} P_{1} \\= \frac{9!}{(9-1)!} \\= \frac{9\times 8!}{8!} \\=9[/tex]

Therefore,

The total number of ways of choosing two piece outfit from 9 blouses and 8 skirts

= [tex]^{8} P_{1} \times ^{9} P_{1}[/tex]

= [tex]8 \times 9[/tex]

[tex]= 72[/tex]

Hence, the total number of ways a girl can choose a two-piece outfit from 9 blouses and 8 skirts is 72.

A ball is thrown vertically upward from the top of a 100-foot tower, with an initial velocity of 20 ft/sec. Its position function is s(t) = -16t^2 + 20t + 100. What is its velocity in ft/sec when t = 1 second?

Answers

The velocity of the ball in ft/sec, when t = 1 second is equal to -12 ft/sec.

Given the following data:

Displacement = 100 feetTime = 1 secondsPosition function = [tex]s(t) = -16t^2 + 20t + 100[/tex]

To calculate the velocity of the ball in ft/sec, when t = 1 second:

Mathematically, the velocity of an object or physical body is equal to the differentiation of it's position function.

Velocity = s'(t)

Velocity = [tex]s(t) = -16t^2 + 20t + 100[/tex]

[tex]Velocity = -32t + 20[/tex]

Substituting the value of time (t), we have:

[tex]Velocity = -32(1) +20\\\\Velocity =-32+20[/tex]

Velocity = -12 ft/sec

I have 40 pieces of facemasks and 32 bottles of alcohol which will be distributed  equally to a group of front liners, if each of them will have the greatest          number of bottles of alcohol and facemasks, how many front liners will receive          each item?         Solution: ___________________________________________________________________         _____________________________________________________________________________​

Answers

Answer:

8 front liners

Step-by-step explanation:

Factorize the numbers:

40 = 2*2*2*532 = 2*2*2*2*2

LCM of the numbers is:

LCM(40, 32) = 2*2*2 = 8

This is a maximum number of front liners.

Each will receive:

40/8 = 5 facemasks and 32/8 = 4 bottles of alcohol

What is the equation of the line that passes through the point (-4, 2) and
has a slope of -2?

Answers

Answer:

y-2 = -2(x+4)

or

y = -2x-6

Step-by-step explanation:

We can use the point slope form of a line

y-y1 = m(x-x1)  where m is the slope and (x1,y1) is a point on the line

y - 2 = -2(x- -4)

y-2 = -2(x+4)

If we want the equation in slope intercept form

Distribute

y-2 = -2x-8

Add 2 to each side

y-2+2 = -2x-8+2

y = -2x-6
