All 3 of the terms have the same base, meaning you just have to combine the terms together (1)x+4x+6x=11x <3
85% of all teachers work in the summer. If you sample 6 random teachers, what is the probability they all work over the summer?
Answer:
[tex]\frac{5}{6}[/tex]
Step-by-step explanation:
Given parameters
Percentage of all teachers the works in summer = 85%
Number of teachers sampled = 6 teachers
Unknown:
The probability that they all work in summer = ?
Solution:
Now, to solve this problem, let us find the number of teachers that works in summer from the given size;
Number of teachers = 85% x 6 = 5.1;
Since it is not possible to have 5.1 people, the number of teachers will be 5
The probability = [tex]\frac{5}{6}[/tex]

Answer:
Slope = -2
Step-by-step explanation:
Since, slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
Rise = -(y-intercept)
Run = (x-intercept)
From the graph attached,
y - intercept = -(4) = -4
x - intercept = 2
Therefore, slope the line given in the graph attached will be,
Slope = [tex]\frac{-4}{2}[/tex] = -2
Slope = -2

Answer: Choice B) The plane is at least 20 times faster than the bird
========================================================
Explanation:
We'll divide the speed of the plane over the speed of the bird.
First divide each coefficient of the scientific value expressions:
7/3 = 2.33 approximately
Then divide the 10^n exponent expressions and we get
10^3 divide by 10^2 = 10^(3-2) = 10^1
So overall, the result of dividing the two speeds leads to approximately
2.33*10^1 = 2.33*10 = 23.3
This shows the plane is approximately 23.3 times faster compared to the bird. Saying "The plane is at least 20 times faster than the bird" is fairly close to the prior sentence, so the statement is valid. That's why choice B is the answer.
Choices A and C are saying similarly valid statements, just written in different formats. I think choice B is the best answer since it seems to be the most direct comparison that is fairly easy to grasp.
g You want to test whether a new commercial increases brand recognition. You use a one-week testing period to evaluate the new ad. The null hypothesis for the test, H0, will be:
Answer:
H0: the new commercial increases brand recognition
Step-by-step explanation:
The null hypothesis is a statement about the given population of interest which is believed to be true and a contradiction of the alternative hypothesis.
In this question, we are testi whether a new commercial increases brand recognition. So the null hypothesis,
H0 would be,
The new commercial increases brand recognition

Predict the violent crime rate for a Southern state with an urbanization of 55.4 and a poverty rate of 13.7.
Answer:
The violent crime rate for this Southern state with an urbanization of 55.4 and a poverty rate of 13.7 is predicted to be:
7.6%.
Step-by-step explanation:
a) Data and Calculations:
Urbanization rate = 55.4%
Poverty rate = 13.7%
The predicted violent crime rate = urbanization rate * poverty rate
= 55.4% * 13.7%
= 7.5898%
= 7.6%
b) The prediction of violent crime rate follows some established researches that show that crime rates are higher in urban than rural areas. There is also a dynamic link between poverty, unemployment, and crime rate. Unemployment is usually high in more urbanized areas. As a result, unemployment increases poverty, and poverty reinforces the commission of crimes.

Answer:
x = 26
2x = 52
(5x - 2) = 128°
Step-by-step explanation:
✔️According to the exterior angle theorem of a ∆, thus:
(5x - 2)° = 2x° + 76°
Solve for x
5x - 2 = 2x + 76
Collect like terms
5x - 2x = 2 + 76
3x = 78
Divide both sides by 3
x = 26
✔️2x
Plug in the value of x
2(26) = 52°
✔️5x - 2
Plug in the value of x
5x - 2 = 5(26) - 2
= 128°

Solve the following system of equations using a method of your choice.
Write the solution as an ordered pair ( , ) and then you will be prompted to explain your thinking.
4x-2y=4
x+y=10
Answer:
Step-by-step explanation:
cant remember what this method is called but
change the second equation to be y = something
x + y = 10
y = -x + 10
plug in this y= in the first equation to get x
4x -2(-x + 10) = 4
4x + 2x -20 = 4
6x = 24
x = 4
then plug in the x we found into the original second equation
4 + y = 10
y = 6
so your ordered pair would be (4,6)

Step-by-step explanation:
A friend recently planned a camping trip. He had two flashlights, one that required a single 6-V battery and another that used two size-D batteries. He had previously packed two 6-V and four size-D batteries in his camper. Suppose the probability that any particular battery works is p and that batteries work or fail independently of one another. Our friend wants to take just one flashlight. For what values of p should he take the 6-V flashlight
Answer:
The values of p = 0 < p ≤ 2/3
Step-by-step explanation:
First we write the probability of 6V flashlight working representing it as a binomial mass function of a binomial random variable
P ( 6v flashlight working ) = P ( at least one 6V battery works )
= P ( 1 6v battery work ) + P ( 2 6v battery work )
= b( 2; 2, p ) + b( 1; 2, p )
write out a formula of b( 2; 2, p ) + b( 1; 2, p )
P ( 6v flashlight working ) = p^2 + 2p( 1 - p )
Next we write the probability of D flashlight working representing it as a binomial mass function of a binomial random variable
P ( D flashlight works ) = p ( at least two D batteries works )
= b( 4; 4, p ) + b(3;4, p ) + b(2; 4, p )
write out a formula of b( 4; 4, p ) + b(3;4, p ) + b(2; 4, p )
P ( D flashlight works ) = [tex]P^4 + 4p^3 ( 1- p ) + 6p^2 ( 1- p)^2[/tex]
attached below is the remaining solution
The machine that Holley operates tightens 40 bolts every 3 minutes. The bolts are delivered to her machine station in boxes containing 1,000 bolts each. Which equation can be used to determine t, the number of minutes it takes Holley's machine to tighten a box of 1,000 bolts at the same tightening rate?
Answer:
75
Step-by-step explanation:
3 divide by 40= 0.0075
0.0075 times 1000= 75

7x - 2 = 9x+5
Please help!!
Answer:
x=-7/2
Step-by-step explanation:
Answer:
x = -7/2 or -3.5
Step-by-step explanation:
7x - 2 = 9x + 5
Add 2 to both sides
7x = 9x + 7
Subtract 9x from both sides
-2x = 7
Divide both sides by -2
x = -7/2
x = -3.5
