Use this formula:
slope = (y₂ - y₁) / (x₂ - x₁)
= (-8 - (-6)) / (2 - 5)
= (-2) / (-3)
= 2/3
which shows two products that result in negative values
Answer:
(2.4)(-1.8) and (0.6)(-0.4)
Step-by-step explanation:
The product of two negative numbers = a positive number. (negative × negative = positive).
Product of two positive numbers = a positive number. (Positive × positive = positive)
Product of a negative number and a positive number = a negative number. (Negative × positive = negative).
Therefore, the answer choice that shows two products that both will result in negative values would be the answer choice that has a negative number multiplying a positive number.
Option 3 has two products in which each has a negative and positive number. That is (2.4)(-1.8) = a negative value, and
(0.6)(-0.4) = a negative value.
Therefore, the answer is Option 3: (2.4)(-1.8) and (0.6)(-0.4)

How long does it take a car travelling at 60 m..p.h to go 5 miles?
Answer:5 minutes
Step-by-step explanation:
Answer:
We are traveling at a speed S = 60 m/h
The distance we are traveling is D = 5m
We know that:
Speed (S) = distance (D)/ Time (T)
60 = 5 / T
==> T = 5/60 = 1/12 hour
==> T = 1/12 * 60 minutes = 5 minutes.
Then, the time needed to travel 5 miles at a 60m/h speed is 5 minutes.

Some descriptive statistics for a Set of test scores are shown above for this test a certain student has a standardized score of z=-1.2 what score did the student receive on the test
Complete Question
The complete question is shown on the first uploaded image
Answer:
The score of the student is x = 779.42
Step-by-step explanation:
Generally we can mathematically represent the z-score as
[tex]z = \frac{x - Mean}{ stDev}[/tex]
Here x is the score of the student
substituting 1045.7 for the Mean, 221.9 for the stDev and -1.2 for z we have
[tex]-1.2 = \frac{x - 1045.7 }{ 221.9}[/tex]
=> [tex]-266.28 = x -1045.7[/tex]
=> x = -266.28 + 1045.7
=> x = 779.42
The student scored 779.42 for him to have a z score of - 1.2;
z score is used to determine by how many standard deviations the raw score is above or below the mean.
The z score is given by:
[tex]z=\frac{x-\mu}{\sigma/ } \\\\where\ x\ is\ raw\ score,\mu\ is\ mean, \sigma\ is\ standard\ deviation[/tex]
Given that μ = 1045.7, σ = 221.9 Hence for z = -1.2:
[tex]-1.2=\frac{x-1045.7}{221.9} \\\\x=779.42[/tex]
The student scored 779.42 for him to have a z score of - 1.2;

The graph of a function g is a transformation of the graph of f(x)=4x−10, where g(x) is 40% of f(x). Write a rule for g.
Answer:
g(x) = 1.6 x - 4
Step-by-step explanation:
Given:
f(x) = 4 x - 10
g(x) is 40% of f(x)
Find:
g(x)
Computation:
⇒ g(x) = 40%[f(x)]
⇒ g(x) = 40%[4 x - 10]
g(x) = 1.6 x - 4
9. You are the sales manager for Solar Panel Company. You receive a commission
based on the total sales of all the salespeople you manage. Your commission is
2 percent of the first $80,000 of sales, 4 percent of the next $80,000, and 5 percent
of all sales over $160,000. What is your commission for a month in which your
salespeople sold $242,100 in solar panels?
Answer: $9705.
Step-by-step explanation:
2 % of first $80,000 sold
= 2/100 * $80,000
= 2 * $800
= $1600
4% of next $80,000
= 4/100 * $80,000
= 4 * $800
= $3,200
if total sales was $242,100. for this Month, the sales person commission would be
= $1600 + 5/100 * 162,100
= $1600 + 5 * $1621
= $1600 + $8105
= $9705.
You are setting up a part-time business with an initial investment of $12,000. The unit cost of the product is $11.50, and the selling price is $19.00.Required:a. Find equations for the total cost C (in dollars) and total revenue R (in dollars) for x units.b. Find the break-even point by finding the point of intersection of the cost and revenue equations units.c. How many units would yield a profit of $1000?
Answer:
Given Initial investment = $12,000
Cost per unit = $11.50
Selling price per unit = $19
a. For x unit
Total cost = Initial investment + Cost per unit * no of unit
= 12,000 + 11.50(x)
c(x) = 12,000 + 11.50(x)
R(x) = Selling price per unit * no of items
R(x) = 19 * x
R(x) = 19x
b. Break even point = R(x) = C(x)
19x = 12,000 + 11.50x
19x - 11.5x = 12,000
7.5x = 12,000
x = 12,000 / 7.5
x = 1600
So, break even point x = 1,600
c. For Profit = $1,000
P(x) = 1,000
P(x) = R(x) - C(x)
1000 = 19x - (12,000 + 11.5x)
1000 =19x - 11.5x - 12000
7.5x = 12000 + 1000
7.5x = 13000
x = 13000/7.5
x = 1733.33
So x = 1733 units
Hence, 1733 units will yield for $1,000 profit

In 1970, 59% of college freshmen thought that capital punishment should be abolished; in 2005, the percentage was 35%. The percentages are based on two independent simple random samples, each of size 1,000. Compute a 95% confidence interval for the difference in the percentages.
Answer:
The 95% confidence interval for the difference in the percentages = [19.75, 28.25]
Step-by-step explanation:
The formula for confidence interval for difference in percentages =
p1 - p2 ± z x √[p1(100 - p1)/n1 + p2(100 - p2)/n2)
From the above question:
p1 = 59%
n1 = 1000
p2 = 35%
n2 = 1000
z = z score of the 95% confidence interval = 1.96
Confidence interval = p1 - p2 ± z x √[p1(100 - p1)/n1 + p2(100 - p2)/n2)
= 59 - 35 ± 1.96 × √[59(100 - 59)/1000] + [35(100 - 35)/1000]
= 24 ± 1.96 × √ [59 × 41/1000] + [35 × 65/1000]
= 24 ± 1.96 × √[2419/1000 + 2275/1000]
= 24 ± 1.96 × √2.419 + 2.275
= 24 ± 1.96 × √(4.694)
= 24 ± 1.96 × 2.1665641001
= 24 ± 4.2464656363
Confidence Interval = 24 ± 4.2464656363
24 - 4.2464656363 = 19.753534364
Approximately = 19.75
24 + 4.2464656363 = 28.2464656363
Approximately = 28.25
Therefore, the 95% confidence interval for the difference in the percentages = [19.75, 28.25]

Solve pls
Hey there!
ANSWER: [tex]p=25[/tex]EXPLANATION:[tex]0.4p-5=0.08p+3[/tex]
To solve this inequality, we will need to subtract 0.08p from both sides of the inequality.
[tex]0.4p-5-0.08p=0.08p+3-0.08p\\0.32p-5=3[/tex]
Now we have to add both sides by 5.
[tex]0.32p-5+5=3+5\\0.32p=8[/tex]
In our last step, we will have to divide both sides by 0.32.
[tex]\frac{0.32p}{0.32} =\frac{8}{0.32}\\25\\\text{25 is your answer.}[/tex]

Set A= {0,3,8}
Set A is not a subset of which set of numbers?
Rational numbers
Integers
Whole numbers
Counting numbers
Set A is not a subset of which set of numbers rational numbers option (A) Rational numbers are correct.
What is set?A set is a collection of clearly - defined unique items. The term "well-defined" applies to a property that makes it simple to establish whether an entity actually belongs to a set. The term 'unique' denotes that all the objects in a set must be different.
It is given that set A:
A ={0, 3, 8}
A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
As we know,
The set of an Integers number = {-∞, ∞}
The set of a whole number = {0, ∞}
The set of a counting number = {-∞, ∞}; all are integer values
Set A is the subset of all the sets shown above.
Thus, set A is not a subset of which set of numbers rational numbers option (A) Rational numbers are correct.

Richard and his friend Julie collect coins as a hobby. Richard has 8 more coins than Julie. If they have 28 altogether how many coins did Julie have?
Answer:
Julie had 10 coins
Step-by-step explanation:
Since there are 28 coins and Richard has 8 more coins than Julie
You can subtract 8 from 28 and get 20
then you would divide 20 by 2 since there are two people( Richard and Julie) Which would give you 10
Since Richard has 8 more coins and each of them have ten you would add 8 to the 10 and you would get 18
Meaning that Richard had 18 coins and Julie had 10 coins
