Maliah goes to an electronic store. Let y represent the price of a laptop and let x
represent the price of a television. The equation y= 3x + 22 relates the prices.
Which of the following statements are true? Select all that apply.
Answers
Answer:
A and C if this was ABCDE
Step-by-step explanation:
150 times 3 plus 22 would equal 450 plus 22 which is 472,
265 times three is 795 plus 22 is 817,
for the BDE, 175 times 3 is 525 plus 22 is 547, 300 times 3 is 900 plus 22 is 922, and 345 times 3 is 1035 plus 22 is 1057

Okay, so what you're basically doing is finding out how much salsa is in the pot. To me, it seems like a trick question.
If two quarts is 2 1/2 of salsa, and they're asking you how much salsa is one quart, you would probably want to simplify 2 1/2. That would come to 2/5. 2/5 simplified would be 0.4 in fractions would total to 1 1/4. That would be your answer.

Able has a younger sister and an older brother. - Able’s age can be represented by x. - Able’s sister is 4 years younger than him. - Able’s older brother is twice as old as he is. - The combined age of all three siblings is 32. How old is Able’s younger sister?
Answers
Answer:
5 years old
Step-by-step explanation:
Able has a younger sister and an older brother.
Able’s age can be represented by x.
Able’s sister (s) is 4 years younger than him. This can be represented as:
s = x - 4 [1]
Able’s older brother (b) is twice as old as he is. This can be represented as:
b = 2x [2]
The combined age of all three siblings is 32. This can be represented as:
x + s + b = 32 [3]
If we replace [1] and [2] in [3], we get:
x + (x - 4) + 2x = 32
4x = 36
x = 9
The age of Able's younger sister is:
s = x - 4 = 9 - 4 = 5

a) 3/3=1
b) 10/10=1
c) 19/19=1
Step-by-step explanation:
yes
a) 1
b) 1
c) 1
Step-by-step explanation:3 x 1/3 =
First we should understand that 3 in fraction form is 3/1.
(3 divided by 1 is three)
So we can rewrite this as;
3/1 x 1/3 =
Now just multiply across
3/1 x 1/3 = 3/3 = 1
Repeating this same logic we'll come across the following answers
10 x 1/10 = 10/10 = 1
19 x 1/19 = 19/19 = 1

What do you have to know about any segments and angles in a figure to decide whether the figure has line symmetry?
Answers
Answer:
Explained below.
Step-by-step explanation:
When drawing line of symmetry on a figure and reflecting, we have to know that pairs of segments in that figure must have the same length while pairs of angles must have the same measurement. This is to ensure that half of that figure must concise with the other half part of it when that figure is folded across a line of symmetry.

a triangular park ABC has side 100cm, 60cm and 80cm. A gardener has to put a fence all around it and also plant grass inside. how much area does she need to plant? find the cost of fencing it with barbed wire at the rate of Rs 50 per meter leaving a space 5m wide for a gate on one side.
Answers
Answer:
Area.
Using Heron's formula to calculate the area, first calculate the semi-perimeter;
= (100 + 60 + 80) / 2
= 120 m
Area = [tex]\sqrt{120 * (120 - 100)(120 - 60)(120 - 80)}[/tex]
= [tex]\sqrt{5,760,000}[/tex]
= 2,400 m²
Cost of fencing.
Perimeter = 100 + 60 + 80 = 240m
Less space for gate = 240 - 5 = 235m
Cost = 235 * Rs 50 per meter
= Rs 11,750
The different units used in your question would lead to an incomprehensible answer so I used meteres for all.

The ratio of the number of men to the number of women in a sports club is 5:2.
After 63 men and 12 women quit the club, the ratio of the number of men to the number of women became 7:4.
How many members did the club have in the beginning?
Answers
Let the number of men and the number of women in the beginning be x and y
Now,[tex]\sf \frac{x} {y} =\frac{5}{2} \\\\\sf
=2x=5y \\\\\sf
=x=\frac{5y}{2}[/tex]
Now, In 2nd case,
No. Of men=x-63 and no. Of women =y-12
Now,the ratio becomes[tex] \frac{x-63}{y-12}=\frac{7}{4} \\\\\sf
=4(x-63)=7(y-12) \\\\\sf
=4x-252=7y-84 \\\\\sf
Putting,\:x=\frac{5y}{2}\:in\: 4x-252=7y-84\:we\: get, \\\\\sf
10y-252=7y-84 \\\\\sf
=10y-7y=252-84 \\\\\sf
=3y=168 \\\\\sf
=y=56 \\\\\sf
=\boxed{Y=56}
[/tex]
Now,we have, 2x=5y
Putting the value of Y=56 in 2x=5y,we get,
[tex]\sf 2x=5\:x\:56 \\\\\sf
x=\frac{5\:x\:56}{2} \\\\\sf
x=\frac{5\:x\: \cancel{56}\:\:28}{ \cancel{2}} \\\\\sf
=x=5\: x\: 28 \\\\\sf
x=140 \\\\\sf
\boxed{x=140}
[/tex]
Hence, the number of men was 140 and the no. of women was 56

In baseball, two statistics, the ERA (Earned Run Average) and the WHIP (Walks and Hits per Inning Pitched), are used to measure the quality of pitchers. For both measures, smaller values indicate higher quality. The following computer output gives the results from predicting ERA by using WHIP in a least-squares regression for the 2017 baseball season.
Answers
Answer:A
Step-by-step explanation:
The best interpretation of the value of 6.8 is shown in the output, ERA is predicted to increase by 6.8 units.
What are statistics?Statistics is the study of the discipline that concerns the organization, collection, analysis, and presentation of data.
In baseball, two statistics, the ERA (Earned Run Average) and the WHIP (Walks and Hits per Inning Pitched), are used to measure the quality of pitchers.
For both measures, smaller values indicate higher quality.
Variable DF Estimate SE T
Intercept 1 −5.0 0.26 −19.3
WHIP 1 6.8 0.14 47.4
ERA is predicted to increase by 6.8 units for each 1 unit increase of WHIP.
Thus, the best interpretation of the value of 6.8 is shown in the output, ERA is predicted to increase by 6.8 units.

D. Fail to reject the claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually greater than 2 in a thousand.
Answers
Answer:
The correct option is (B).
Step-by-step explanation:
A type-I-error occurs when we discard a true null-hypothesis (H₀).
The hypothesis in this case are:
H₀: The proportion of Americans that have seen a UFO is 0.002, i.e. p = 0.002.
Hₐ: The proportion of Americans that have seen a UFO is less than 0.002, i.e. p < 0.002.
A type I error will be committed, if we reject the claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually 2 in a thousand.
The correct option is (B).

You know that the Customer Acquisition Cost is the cost associated with convincing a customer to buy a good or service. It includes the product, research, marketing, and accessibility costs. You also know that it equals the marketing expenses per month divided by the number of new customers per month.
You have determined that two certain groups of customers are the largest groups of buyers. You want to know which group will be more profitable to target in terms of marketing. You check the company’s big data and find that the marketing expense per month for targeting the first group is $30,000, while the second group requires $60,000. You estimate that this marketing campaign will be able to attract 1,000 new customers for demographic group 1 and 1,500 for demographic group 2.

d. $100.
Answers
Answer:
The Customer Acquisition Cost for each customer in demographic group 1
The correct option is c
The Customer Acquisition Cost for Group 2
The correct option is b
Step-by-step explanation:
From the question we are told that
The marketing expenses per month for targeting the first group is [tex]E = \$ 30,000[/tex]
The marketing expenses per month for targeting the second group is [tex]F = \$ 60,000[/tex]
The number of customers for the demography of group 1 that will be attracted is N = 1000
The number of customers for the demography of group 2 that will be attracted is M = 1500
Generally the customer acquisition cost for group 1 is
[tex]K = \frac{E}{ N}[/tex]
=> [tex]K = \frac{30000}{ 1000}[/tex]
=> [tex]K = \$ 30 [/tex]
Generally the customer acquisition cost for group 2 is
[tex]Z = \frac{F}{ M}[/tex]
=> [tex]Z = \frac{60000}{ 1500}[/tex]
=> [tex]Z = \$ 40 [/tex]
