URGENTT!!!!!!!

A simple random sample of
150 San Antonio area policemen found that the average time these police officers had worked for the police department was 16
years with a standard deviation of 5 years. Ten years ago the average amount of time policemen stayed on the job was 15 years.

What is the test statistic And P value that the researchers will use for this significance test?

Answer:

= 0

Step-by-step explanation:

by using reminder theorem,

let, x - 1 = 0

then,

x = 1

plag in

1^4 + 1^2 - 2(1)^2 + 1 + 1

1 + 1 - 4 + 2

2 - 4 + 2

2 - 2

= 0

that's what I think.

Answer:

[tex]\text{First number: }-10, \\\text{Second number: }-4[/tex]

Step-by-step explanation:

We can write the following system of equations:

Let the first number be [tex]f[/tex] and the second number be [tex]s[/tex]:

[tex]\begin{cases}f+6=s, \\2f-4=6s\end{cases}[/tex]

Solving, we get:

[tex]\int\limits^a_b {x} \, dx \begin{cases}f+6=s, \\2f-4=6s\end{cases},\\2f-4=6(f+6),\\2f-4=6f+36,\\-40=4f,\\f=\boxed{-10}[/tex]

Solving for [tex]s[/tex]:

[tex]f+6=s,\\-10+6=s,\\s=\boxed{-4}[/tex]

Answer:

the answer to C. Is 3/8.

The answer to D. Is 5/8.

Step-by-step explanation:

Answer:

x = 0.1854 and x = -16.1854

Step-by-step explanation:

refer to photo

Given:

[tex]\sin^{-1}\left(\dfrac{5}{8}\right)=A[/tex]

To find:

The correct equivalent equation.

Solution:

We have,

[tex]\sin^{-1}\left(\dfrac{5}{8}\right)=A[/tex]

Taking sin on both sides, we get

[tex]\sin \sin^{-1}\left(\dfrac{5}{8}\right)=\sin A[/tex]

[tex]\dfrac{5}{8}=\sin A[/tex]                      [tex][\because \sin (\sin^{-1}\theta )=\theta][/tex]

Interchanging the sides, we get

[tex]\sin A=\dfrac{5}{8}[/tex]

Therefore, the correct option is 4.

Answer:

8 meters per second

Step-by-step explanation:

We can divide meters by seconds to get his average speed in meters per second. -- 640 m / 80s = 8 m/sec (meters per second). We can also figure out his average speed in minutes by multiplying 8 by 60 (because there are 60 seconds in a minute), 8 * 60 = 480 m/min (meters per minute).

Answer:

8m/s

Step-by-step explanation:

Speed is equal the distance upon time.

640/80

so speed is equal to 8m/s

Answer:

"Spurious relationship" is the correct answer.

Step-by-step explanation:

The relationship between the independent and dependent variables in this case can be referred to as: spurious relationship.

A spurious relationship can be described as a statistical association between two variables, which are claimed to be directly connected to each other, and may in fact, just be a coincidence or may have been connected together by an intermediate or third factor when carefully examined.

Therefore, the relationship between the independent and dependent variables in this case can be referred to as: spurious relationship.

Answer:

x = 5/7

Step-by-step explanation:

Here, we want to get the value of x

Firstly, according to indices;

(a^m)^n = a^(m * n) = a^mn

Also;

a^m * a*n = a^(m + n)

a^0 = 1 (any number raised to zero as its power is 1)

And lastly;

a^m divided by a^n = a^(m-n)

So using these we can have;

7^4x = 7^( 2 + 3)/7^3x

7^4x = 7^5/7^3x

7^4x = 7^(5-3x)

Since we have the same bases, we have to equate the powers

4x = 5-3x

4x + 3x = 5

7x = 5

x = 5/7

Answer:

64 times

Step-by-step explanation:

There are 4 sessions of 15 minutes in an hour. Meaning that a person would vape 4 times in an hour. 4 * 16 = 64. A person vapes 64 times in 16 hours. o-o dont vape kids.

Answer and Step-by-step explanation:

We are given the ratio of 1 vape every 15 minutes. We need to convert the time to hours, then multiply the hours by 16.

1 : 15

We know that there are 60 minutes in 1 hour, so we need to multiply 15 by 4 to get 60.

15 × 4 = 60

We also need to multiply 1 by 4, so that the result will be a multiple of the beginning number and so that we didn't get random numbers from somewhere.

1 × 4 = 4

Now we have the ratio 4 : 60, which means that the person vapes 4 times every 60 minutes, or every hour. But since we turned the minutes into an hour, this turns the 60 into a 1.    4 : 1

Now, we have to multiply 4 and 1 by 16 to get the amount of vapes done in 16 hours.

4 × 16 = 64

1 × 16 = 16

So, we have the ratio 64 : 16

This means that the person smokes 64 times in the 16 hours.

⎆ The value of m is 8.

ʰᵒᵖᵉ ⁱᵗ ʰᵉˡᵖˢ

# ꧁❣ RainbowSalt2²2² ࿐

Answer:

p=30, m=8

Step-by-step explanation:

1. if p - 17 = 13, then p = 13+17, which is equal to 30

2. if 23 + m = 31, then m = 31-23, which is equal to 8

Do the opposite of the sign, for instance in question 1 it's -17, so you would +17 to calculate p.

Answer:

If a flight just left on-time, the probability that it was a flight of airline A is 56.06%.

Step-by-step explanation:

Since three airlines serve a small town in Ohio, and Airline A has 48% of all scheduled flights, airline B has 35% and airline C has the remaining 17%, and their on-time rates are 81%, 70%, and 41%, respectively, if a flight just left on-time, to determine what is the probability that it was a flight of airline A the following calculation must be performed:

A = 0.48 x 0.81 = 38.88

B = 0.35 x 0.7 = 23.5

C = 0.17 x 0.41 = 6.97

38.88 + 23.5 + 6.97 = 100

38.88 = X

69.35 = 100

38.88 = X

38.88 x 100 / 69.35 = X

3,888 / 69.35 = X

56.06 = X

Therefore, if a flight just left on-time, the probability that it was a flight of airline A is 56.06%.

Answer:

x = 12, x = 7

Step-by-step explanation:

The 2 legs of the triangle are congruent, both 2x + 7, then

2x + 7 + 2x + 7 + x + 11 = 85 ← equation for perimeter

5x + 25 = 85 ( subtract 25 from both sides )

5x = 60 ( divide both sides by 5 )

x = 12

-----------------------------------------------------------

Opposite sides are congruent, then

2(2x) + 2(5x + 3) = 104 ← distribute and simplify both sides

4x + 10x + 6 = 104

14x + 6 = 104 ( subtract 6 from both sides )

14x = 98 ( divide both sides by 14 )

x = 7
