Answer:
I think its A
Step-by-step explanation:
a. The equation of the trend line is c=5x+100.
b. The equation of the trend line is c=-5x+100.
c. As the hours of training increase by 5, the greeting cards made increases by 25.
d. As the hours of training increase by 5, the greeting cards made decreases by 25.
Answer:
The slope of the line of best fit is 5.
Without any training, an employee is expected to make 100 greeting cards.
If an employee has 70 hours of training, the employee is expected to make 450 greeting cards per month.
Step-by-step explanation:
First, find the slope of the line of best fit by substituting any two points on the line into the slope formula. The following calculation uses (10,150) and (20,200).
So, the slope of the line of best fit is 5.
The y-intercept is the point at which the line crosses the y-axis or when x = 0. So, the y-intercept of the line of best fit is 100.
The equation of the line of best fit can be represented in slope-intercept form, where the slope, m, is 5 and the y-intercept, b, is 100.
A slope of 5 in this situation means that for every additional hour of training, 5 more greeting cards are expected to be made per month. The y-intercept is 100 when the number of hours of training is 0. So, without any training, an employee is expected to make 100 greeting cards.
To find the number of greeting cards an employee would produce after receiving 70 hours of training, substitute x = 70 into the equation for the line of best fit and solve for y.
So, if an employee has 70 hours of training, the employee is expected to make 450 greeting cards per month.

WHAT IS EQUIVALENT TO THE INEQUALITY 2X>6?
Answer:
x > 3
Step-by-step explanation:
Simply isolate the inequality to get a equivalent inequality. Treat the sign > like an equal sign, what you do to one side, you do to the other side of the inequality.
Isolate the variable, x. Divide 2 from both sides of the equation:
(2x)/2 > (6)/2
x > 6/2
x > 3
x > 3 is your equivalent inequality.

Airline Fatalities One study showed that in a certain year, airline fatalities occur at the rate of 0.011 deaths per 100 million miles. Find the probability that, during the next 100 million miles of flight, there will be
Answer:
[tex]P(X = 0) = 0.9891[/tex]
Step-by-step explanation:
Given
[tex]\lambda = 0.011[/tex]
Required [This completes the question]
The probability of exactly 0 deaths
This probability follows a Poisson distribution, and it is given by:
[tex]P(X = x) = \frac{e^{-\lambda}\lambda^{x}}{x!}[/tex]
For 0 deaths;
[tex]x = 0[/tex]
So, the expression becomes
[tex]P(X = 0) = \frac{e^{-\lambda}\lambda^{0}}{0!}[/tex]
[tex]P(X = 0) = \frac{e^{-\lambda}\lambda^{0}}{1}[/tex]
[tex]P(X = 0) = \frac{e^{-\lambda}*1}{1}[/tex]
[tex]P(X = 0) = e^{-\lambda}[/tex]
Substitute 0.011 for [tex]\lambda[/tex]
[tex]P(X = 0) = e^{-0.011}[/tex]
[tex]P(X = 0) = 0.9891[/tex]
The probability of having exactly death is 0.9891
4. (A). Use the digits 1, 6, 7 and 5 to form the greatest 4-digit even
number.
(B). Divide the answer in (A) by 8.
Answer:
A)5176
B)647
Step-by-step explanation:
5176 is the highest even number that is divisible by 8
Step-by-step explanation:
7-5= 2
5-1= 4
5+1 =6
7+1= 8
therefore, the four digits even number are 2,4,6,8
What is the area of the composite figure?
Answer:
59.5
Step-by-step explanation:
Fig = square + triangle
Area of square = s x s = 7^2 = 49 sq.cm
Area of triangle = 1/2 bh = 1/2 x 3 x 7 = 10.5 sq.cm
Area of fig = area of sq + area of triangle = 49 + 10.5 = 59.5 cm^2

PLEASE HELP FAST 20 POINTS! Housing prices are often reported using a median. Why is median used in this case? Would arithmetic mean or mode reasonable for comparing housing prices?
Step-by-step explanation:
The red line in the graph above measures the median home price, and this is often a better "average" for us to be used with home prices and home values. Unfortunately, it is not as easy to calculate and it does not work well with tiny data sets, so we often only see it used with very large data sets (like whole Cities, States, etc.) produced by the large real estate aggregators. Additionally, not many real estate agents know how to generate them for neighborhoods or zip codes (but we can at the Tallahassee Real Estate Blog :)).

A group of friends met for dinner to get some pizza each friend ate 2/3 of a pizza enter the total amount of pizza the frends ate
Answer: See explanation
Step-by-step explanation:
You didn't specify the number of friends which is missing in the question. To solve this question, we need to know the number of friends but let's assume that the number of friends are 6.
Since each friend ate 2/3 of a pizza and there are 6 friends, the total amount of pizza the frends ate will be:
== 2/3 × 6
= 4 pizzas

Based on these results, express the probability that a seventh grader chosen at
random will play the guitar as a fraction in simplest form?
Answer:
[tex]Probability = \frac{11}{40}[/tex]
Step-by-step explanation:
Given
See attachment
Required
The probability that a 7th grader selected will play guitar.
From the attachment, we have:
[tex]7th\ graders =11+8+8+13[/tex]
[tex]7th\ graders =40[/tex]
7th graders that can play guitars are:
[tex]Guitars = 11[/tex]
So, the probability is:
[tex]Probability = \frac{Guitars}{7th\ graders}[/tex]
[tex]Probability = \frac{11}{40}[/tex]
This graph shows the solution to which inequality?
Answer:
Where is the graph of this question?
Please help. Will give brainliest
Answer:
Step-by-step explanation:
(-2,2) lies above the vertex, so the parabola opens upwards.
Vertex-form equation for an up-opening parabola with vertex (-5,-1):
y = a(x+5)² - 1, a>0
Plug in (-2,2) and solve for a:
2 = a(-2+5)² - 1
a = ⅓
Equation of parabola:
y = ⅓(x+5)² - 1

Which two expressions are equivalent to 2(5x + 2 + x)?
a
A and C
b
B and D
c
A and D
d
B and C
Answer:
b and d
Step-by-step explanation:
2(5x+2+x)=12x+4(b)
2(6x+2)=12x+4
First, solve the expression.
2(5x+2+x)
10x+4+2x
12x+4
So we know that one of the answers is B. and not A.
C. 2(5x+3)
10x+6
D. 2(6x+2)
12x+4
So the answers are B and D, or option B

Willa and her friend decide to hang out at her friend’s house after basketball practice on Friday to listen to a new album by their favorite band. They have a great time listening to the music and Willa deliberately ignores texts from her dad. When she gets home, her dad is really upset with her. He didn’t know where she was. He has a rule that he needs to know where she is and that she has to ask permission before she goes anywhere. Willa thinks that since she’s in eighth grade, she shouldn’t have to do this anymore. Her dad should trust her more. Willa tells her dad that she’s not a little kid anymore and storms off to her room and slams the door.
