Please help with this I just wanna make sure I’m correct.

Answer:

Step-by-step explanation:

man the formula is right there!

two points: (3,2) and (7,5)

[tex]y_2=5\\y_1=2\\x_2=7\\x_1=3\\slope=\frac{5-2}{7-3}=.75[/tex]

Answer:

s≥11

Step-by-step explanation:

5 ≤ s -6

=5 + 6 ≤ s

=11 ≤ s or s≥11

The solution to given inequality  5 ≤ s − 6 for s will be s ≥ 11.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

Inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

Given the inequality,

5 ≤ s − 6

Subtracting by 5 on both sides,

5 - 5 ≤ s - 6 - 5

0 ≤ s - 11

Adding 11 on both sides

0 + 11 ≤ s - 11 + 11

11 ≤ s or s ≥ 11

Hence "The solution to given inequality  5 ≤ s − 6 for s will be s ≥ 11".

Using the normal distribution and the central limit theorem, it is found that:

a) The 90th percentile for an individual teacher's salary is $50,216.

b) The 90th percentile for the average teacher's salary is $43,914.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

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

In this problem:

Item a:

The 90th percentile is X when Z has a p-value of 0.9, so X when Z = 1.28. Thus:

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

[tex]1.28 = \frac{X - 41000}{7200}[/tex]

[tex]X - 41000 = 1.28(7200)[/tex]

[tex]X = 50216[/tex]

The 90th percentile for an individual teacher's salary is $50,216.

Item b:

Average for a sample of 10, thus [tex]n = 10, s = \frac{7200}{\sqrt{10}}[/tex].

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

By the Central Limit Theorem

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

[tex]1.28 = \frac{X - 41000}{\frac{7200}{\sqrt{10}}}[/tex]

[tex]X - 41000 = 1.28\frac{7200}{\sqrt{10}}[/tex]

[tex]X = 43914[/tex]

The 90th percentile for the average teacher's salary is $43,914.

Answer:

D. Subtract 15 cents and add 29 cents

Step-by-step explanation:

He should subtract 15 cents and add 29 cents. This is because at 33.85 we estimated to 34 dollars which was 15 cents higher, so we must subtract by 15 to get to the exact cost. We also need to add 29 cents since we rounded down from 16.29 to 16.

Answer

15=20t

Step-by-step explanation:

Answer:

t = 15 / 20

Step-by-step explanation:

Given:

Distance traveled by Deon to ride a bicycle trail = 15 mile

Average speed of Deon to ride a bicycle trail = 20 mi/hour

Step-by-Step:

Let 'T' be the time taken to ride the bicycle trail.

We will use distance speed formula to write the equation to find the time 'T' in hours, for the ride.

[tex]Distance=\frac{Speed}{Time}[/tex]

Distance = 15 miles

Speed = 20 miles / hour

Time = 15 / 20

Assuming time is t, the formula would be:

t = 15 / 20

"t = 15 mi/ 20 mi/hr " will help Deon calculate the time he will take.

Therefore, t = 15 / 20

Answer: I believe it's 22

Step-by-step explanation:

51 - 7 = 44

If the result is 55 and was increased by 7, you'll subtract 7 from 55 and you'll get 44.

44/2 = 22

To find the number that is doubled and makes up 44, you'll divide 2 from 44 and you'll get 22

4 = x

Step-by-step explanation:

To solve for the value of x

-36 = -3x -4 -5x

Transpose and solve

-36 = -8x -4

-36 + 4 = -8x

-32 = -8x

-32 ÷ -8 =x

Both the negative signs will be cancelled

4 = x

Answer:

  $3386.40

Step-by-step explanation:

The amount at the end of March can be found two ways:

  add up the deposits for Jan, Feb, Mar:

     1200.32 +985.43 +1200.65 = 3386.40

  subtract Apr and May from the May total:

     6374.72 -1000.98 -1987.34 = 3386.40

The total amount of money that he had deposited into his account at the end of March is $3386.40.

Answer:

a 3.5 % return is .035/12 - .002917 / mo

10 years is 120 mos.

This is basically an annuity payment - after 10  years 1$, deposited monthly, would be worth (similar to house mortgage, etc.)

N = (1 - (1 + i)^-120) / i  = 241.73

Total amount = 25 * 241.73 = 6043

Note 120 payments at $25 = 3000
