Assume new York’s state salaries follow a normal distribution. (A) what percent of new York’s high school teachers earn between 83,000 and 88,000? (B) what percent of New York teachers earn between 88,000 and 103,000?
(C) what percent of new York’s state high school teachers earn less than 73,000?

Answers

Answer 1

a. 20.31% of New York's high school teachers earn between 83,000 and 88,000

b.  18.49% of New York teachers earn between 88,000 and 103,000

c. 1.19%  of New York’s state high school teachers earn less than 73,000

Given,

The salary for high school teachers in 2017 = 97010

Standard deviation = 9540

Consider salaries as normal distribution.

Here,

Mean, μ = 97010, Standard deviation, σ = 9540

a. Percentage of New York's high school teachers earn between 83,000 and 88,000

The proportion is the p-value of Z when X = 88,000 subtracted by the p-value of Z when X = 83,000.

That is,

X = 88,000

Z = (X - μ) / σ = (88,000 - 97010) / 9540 = -9010/9540 = -0.944

The p value of z score - 0.944 is 0.3452

Next,

X = 83,000

Z = (X - μ) / σ = (83,000 - 97010) / 9540 = -14010/9540 = -1.468

The p value of z score - 1.468 is 0.1421

Then,

0.3452 - 0.1421 = 0.2031 = 20.31%

That is,

20.31% of New York's high school teachers earn between 83,000 and 88,000

b. Percentage of New York teachers earn between 88,000 and 103,000

The proportion is the p-value of Z when X = 103,000 subtracted by the p-value of Z when X = 88,000

X = 103,000

Z = (X - μ) / σ = (103,000 - 97010) / 9540 = 5990/9540 = 0.6279

The p value of z score 0.6279 is 0.5301

Next,

X = 88,000

Z = (X - μ) / σ = (88,000 - 97010) / 9540 = -9010/9540 = -0.944

The p value of z score - 0.944 is 0.3452

Then,

0.5301 - 0.3452 = 0.1849 = 18.49%

That is,

18.49% of New York teachers earn between 88,000 and 103,000

c.  Percentage of new York’s state high school teachers earn less than 73,000

The proportion is the p-value of Z when X = 73000

X = 73,000

Z = (X - μ) / σ = (73,000 - 97010) / 9540 = -24010/9540 = -2.516

The p value of z score - 2.516 is 0.0119

That is,

1.19%  of New York’s state high school teachers earn less than 73,000

Answer:

Step-by-step explanation:

1.175

1.175

-1.175

1.175

First find the closest values possible to 0.88 (88%) on the z-score table. Once found we can see that it is located at positive 1.1 and directly in-between .07 and .08. Therefore we take the half of the two, .075, and get the answer of 1.175. The positive z-score, 1.175, tells us that we are 1.175 standard deviations above the mean.

Second find the closest values possible to 0.12 (12%) on the z-score table. We find it at -1.1 and perfectly in-between .07 and .08. We repeat the same steps as before and get -1.175. The negative z-score, -1.175, tells us the we are 1.175 standard deviations below the mean.

Answers

The total finance charge is $360.

Given:

Alondra bought a $1,700 television on an installment plan.

The installment agreement included a $170 down payment and 18 monthly payments of $105 each.

Total amount paid = down payment + payment of each month * number of months.

= 170 + 105 * 18

= 170 + 1890

Total amount paid = $2060

Total finance charge = total amount paid - $1700

= $2060 - $1700

= $360.

Personal finance Funding a retirement goal. Austin Miller wishes to have $800,000 in a retirement fund 20 years from now. He can create the retirement fund by making a single lump-sum deposit today.   How much would Austin need to have on deposit at retirement in order to withdraw $35,000 annually over the 15 years if the retirement fund earns 4 percent?   To achieve his annual withdrawal goal of $35,000 calculated in part b, how much more than the amount calculated in part a must Austin deposit today in an investment earning 4 percent annual interest?

Answers

Answer:

$389,200

$21,200

Since,

[tex]\text{PMT}=\frac{PV}{\text{PVA}}[/tex]

We are to find PV when the PMT is $35000. Since the PVA is 11.12,

[tex]PV=\text{PVA}\cdot\text{PMT}[/tex][tex]PV=(11.12)(35000)=389200[/tex]

Hence, Austin would need to deposit $389,200.

For the last part, we first need to solve the PV at 4% in 20 years.

The PVIF would be:

[tex]\text{PVIF}=\frac{1}{(1+0.04)^{20}}=0.46[/tex]

Then, solving for the PV:

[tex]PV=800000(0.46)=368000[/tex]

Now, to know how much more should Austin deposit, we need to subtract the original PV from the PV that we got from part B.

That would be,

[tex]389200-368000=21200[/tex]

Austin would need to deposit $21,200 more to achieve his withdrawal goal.

Answers

Answer

Event 3, Event 2, Event 4, Event 1.

Explanation

Given data:

Box A has 6 purple pens and 2 blue pens.

Box B has 12 purple pens and 8 blue pens.

Let X represents purple, Y represents blue, and Z represents red.

Box A: n(X) = 6, n(Y) = 2, and n(Z) = 0. Hence, n(S) = 6 + 2 + 0 = 8

Box B: n(X) = 12, n(Y) = 8, and n(Z) = 0. Hence, n(S) = 12 + 8 + 0 = 20

So if a pen is randomly chosen from each box, the probability of:

Event 1: choosing a purple or blue pen from Box B. will be:

[tex]\begin{gathered} p(X\text{ or Y})=p(X)+p(Y)=\frac{n(X)}{n(S)}+\frac{n(Y)}{n(S)}=\frac{12}{20}+\frac{8}{20}=\frac{12+8}{20}=\frac{20}{20}=1 \\ \end{gathered}[/tex]

Event 2: choosing a blue pen from Box B will be:

[tex]p(Y)=\frac{8}{20}=\frac{1}{5}=0.4[/tex]

Event 3: choosing a red pen from Box A will be:

[tex]p(Z)=\frac{n(Z)}{n(S)}=\frac{0}{8}=0[/tex]

Event 4: choosing a purple pen from Box A wil be:

Part a. Solving for x,

1/x - 1/(x+1) = 3

(1-x+x)/x(x+1) = 3

1/(x²+x) = 3

1 = 3x²+3x

t= [10±0]/50

t= 1/5

Part d. Solving for t;

0 = √[(1 + t)²+(1 − 2t)²]

Squaring both sides,

(1+t)² =-(1-2t)²

1+t²+2t = -(1+4t²-4t)

What are the steps of adding and subtracting fractions?

The steps for adding and subtracting fractions are as follows:

Step 1: Match the denominators.

Step 2: Add and subtract the numerators.

Step 3: Make the fraction simpler.

Fractions with different denominators can be added or subtracted by using Least Common Multiple(LCM) to convert them to like fractions.

a) 4/5 - 1/5

The denominators of the fractions are the same so we have to just subtract the numerators.

= (4 - 1)/5

= 3/5

b) 9/11 + 5/11

Similarly, the denominators of these fractions are also equal so we have to just add the numerators.

= (9 + 5)/11

= 14/11

c) 3/4 + 1/8

First, we find the Least Common Multiple (LCM) of the denominators to convert them into like denominators and then add the respective numerators.

[tex]\frac{3}{8}[/tex] = [tex]\frac{x}{120}[/tex]       x equals the unknown actual biscuit count.

8 x 15 =120, so solve for x by multiplying 3 by 15

x = 45

Answer:

15

Step-by-step explanation:

equation=

[tex]5x+3x=120\\equals..\\8x=120\\x= 15[/tex]

There are 15 packets each of both sweets and biscuits.

Check!

[tex]5(15)=75[/tex] sweets

[tex]3(15)=45[/tex] biscuits

[tex]75+45=120[/tex] sweets and biscuits altogether

Hence, there are 15 packets of biscuits.

Given functions are:

[tex]\begin{gathered} f(x)=x+2 \\ g(x)=x-4 \end{gathered}[/tex]

So:

[tex]\begin{gathered} f(x)\times g(x)=(x+2)(x-4) \\ f(x)\times g(x)=x^2-4x+2x-8 \\ f(x)\times g(x)=x^2-2x-8 \end{gathered}[/tex]

we know a^2 + b^2 = c^2. However, we only have c^2 and b^2. So we must find in terms of a^2, and so the formula becomes a^2 = c^2 - b^2. When we plug in the numbers, we get 144 - 16 = 128, and so we just find the square root of 128.
