Answer:
y-intercept is (0,5)
Step-by-step explanation:
When a graph passes through (0,a), that's y-intercept. y-intercept is a point on y-plane that a graph passes through.
For Ex. If a graph passes through (0,4) then the y-intercept would be (0,4).
But remember that it must be (0,a) for it to be y-intercept (Because it has to intersect the y-plane)

Dr. Khan works for the marketing department of a company that manufactures mechanical toy dogs. Dr. Khan has been asked to assess the effectiveness of a new advertising campaign that is designed to be most persuasive to people with a certain personality profile. She brought four groups of participants to the lab to watch the video advertisements and to measure the likelihood that they would purchase the toy, both before and after watching the ad. The results of Dr. Khan’s study are presented below.
Part A
Explain how each of the following concepts applies to Dr. Khan’s research.
Survey
Dependent variable
Big Five theory of personality
Part B
Explain the limitations of Dr. Khan’s study based on the research method used.
Explain what Dr. Khan’s research hypothesis most likely was.
Part C
Use the graph to answer the following questions.
How did the trait of agreeableness affect how people responded to the new ad campaign?
How did the trait of conscientiousness affect how people responded to the new ad campaign?
Answer:
3 [tex]\frac{7}{8}[/tex]
Step-by-step explanation:
To find the largest number add the value of the range to the smallest number.
- 2 [tex]\frac{3}{8}[/tex] + 6 [tex]\frac{1}{4}[/tex] ( change to improper fractions )
= - [tex]\frac{19}{8}[/tex] + [tex]\frac{25}{4}[/tex]
= - [tex]\frac{19}{8}[/tex] + [tex]\frac{50}{8}[/tex]
= [tex]\frac{31}{8}[/tex]
= 3 [tex]\frac{7}{8}[/tex]
what is 9-x/5=3?
I kept getting 6 but the only option is -6 :/
Step-by-step explanation:
[tex]9 - \frac{x}{5} = 3 \\ 9 - 5 \times \frac{x}{5} = 3 \times 5 \\ 9 - x = 15 \\ - 9 - x = - 9 + 15 \\ - x = 6 \\ - x \div - 1 = 6 \div - 1 \\ x = - 6[/tex]
Answer:
Yeah the answer is -6
Step-by-step explanation:
9-x/ 5= 3
9-x = 15 (5 times three)
-x = 6 (9-6)
x= -6 ( a variable can never Be negative, but we have to give the minus to 6)

A company’s mean salary is $65,000 with a standard deviation of $6,000. What is the probability that an employee makes between $70,000 and $80,000?
An employee has a probability of 0.19706 to make between $70,000 and $80,000
What is Probability?Probability is the potential for an event to occur or occur, and it indicates the likelihood that a statement is true. It is a field of mathematics where the probabilities of experiments happening are computed. We can determine everything from the likelihood of getting heads or tails when tossing a coin to the likelihood of making a research error, for instance, using a probability. It's formula is = number of favorable outcomes/total number of outcomes
Let X be the annual salary of employees in a large company.
Given the mean salary is $65,000 and the standard deviation is $6,000, the probability of making between $70000 and 80000 can be calculated as:
[tex]P(70000 < X < 80000)[/tex] = [tex]P(\frac{70000 - 65000}{6000} < z < \frac{80000 - 65000}{6000} )[/tex]
[tex]P(0.833 < z < 2.5)[/tex]
= 0.99379 - 0.79673 (from normal distribution table)
= 0.19706
Hence, the probability that an employee makes between $70,000 and $80,000 is 0.19706

Step-by-step explanation:
Given the equation
-3x - 21 = 27
We are to find the next step in solving the equation
Step 1: Add 21 to both sides
-3x - 21 + 21 = 27 + 21
-3x = 48
Step 2: Divide both sides by -3
-3x/3 = 48/3

Answer:
The probability of spinning red is [tex]\frac{1}{3}[/tex], the probability of spinning a 1 is [tex]\frac{1}{6}[/tex], the probability of spinning an odd number is [tex]\frac{1}{2}[/tex], and the probability of spinning a 9 is 0.
Step-by-step explanation:
Since there are a total of 6 possible outcomes, you can use this in the following questions. There are 2 red tiles, so the probability of spinning red is [tex]\frac{2}{6}[/tex] or [tex]\frac{1}{3}[/tex]. Since there are only one 1 tile, the probability of spinning a 1 is [tex]\frac{1}{6}[/tex]. Since there are three odd numbers, the probability of spinning an odd number is [tex]\frac{1}{2}[/tex]. Since there are no 9 in the spinner, the probability of spinning a 9 is 0 or never.

Jack is selling used computers. he is paid $15/h plus a 5% commission on sales. What dollar amount of computer sales must jack make to earn $1000 in a 40-h work week.
Answer:
8000
Step-by-step explanation:
Jack sold worth $8000 computer sales in the last week.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, Jack is selling used computers. He is paid $15/h plus a 5% commission on sales.
He made $1000 in a 40-h week,
∴ He made $(15×40) = $600 for his work hours and $(1000 - 600)
= $400.
So, $400 dollars in 5% of the total sales and assuming he made a sell of $x.
∴ (5/100)×x = 400.
0.05x = 400.
x = 400/0.05.
x = 8000.

A farmer sells 8.6 kg of Pierce an apple at the Farmers Market two fifths of the wait is pears and the rest is apples how many kilograms of apples did she sell at the Farmers Market
Answer:
Weight of Pears = 3.44 Kgs
Weight of Apple = 5.16 Kgs
Step-by-step explanation:
Given
The total weight of the Pears and the apple is 8.6 Kg
Out of this total weight, the weight of the pears is 2/5
Hence, weight of the Pears is 2/5 * 8.6 = 3.44 Kg
Weight of the Apple is equal to 8.6 -3.44 Kgs = 5.16 Kgs
Weight of Pears = 3.44 Kgs
Weight of Apple = 5.16 Kgs

If you place a 37-foot ladder against the top of a 15-foot building, how many feet will the bottom of the ladder be from the bottom of the building? Round to the nearest tenth of a foot.
Answer:
33.8
Step-by-step explanation:
a²+b²=c²
15²+b²=37²
225+b²=1369
-225 -225
b²=1144
√1144
b=33.8
The distance from the bottom of the ladder to the bottom of the building would be 33.8 foot.
What is Pythagoras' Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
|AC|^2 = |AB|^2 + |BC|^2
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
If you place a 37-foot ladder against the top of a 15-foot building.
Let BC be the distance from the bottom of the ladder to the bottom of the building.
[tex]|AC|^2 = |AB|^2 + |BC|^2 \\15^2+BC^2=37^2\\225 + BC^2=1369\\BC^2 = 1369 - 225\\\\BC^2 = 1144\\\\BC = 33.8[/tex]
