Answer:
x=4, y=-3. (4, -3).
Step-by-step explanation:
5x+4y=8
2x-3y=17
--------------
2(5x+4y)=2(8)
-5(2x-3y)=-5(17)
---------------------
10x+8y=16
-10x+15y=-85
-----------------
23y=-69
y=-69/23
y=-3
5x+4(-3)=8
5x-12=8
5x=8+12

Experts believe that 70% of adults in the United States believe it is more enjoyable to be married than single. An ABC News Poll in 2004 surveyed 1,501 randomly selected adults in the United States and asked if they believed it is more enjoyable to be married or single. In the survey, 1,126 people responded that it is more enjoyable to be married. Suppose another 1051 random selected U.S. adults were surveyed and asked if they believed it is more enjoyable to be married or single. The sample proportion who respond that it is more enjoyable to be married from this new sample would most likely be different from the same sample proportion from the old sample due to ___________________.
Answer:
Due to;
Sampling variability
Step-by-step explanation:
From the question, we have;
The percentage adults experts believe are convinced that it is more enjoyable to be married than single = 70%
The number of adults in the sample of the survey = 1,501 adults
The number of adults that responded that it is more enjoyable to be married than single = 1,126
According to the central limit theorem, the differences in the two samples and the small sizes of the samples compared to the population, the sample means is different from the population mean, therefore, the sample proportion that respond that it is more enjoyable to be married from the new sample will be different from the old sample due sampling variability because as the sample size is so small compared to the population, some samples can contain more of one category in the population than other samples leading to varying proportion

Although it is now extinct, the Carolina parakeet was last seen in Florida in 1920. Back then, large areas of habitat were logged and converted to agricultural fields. Honeybees evicted the parakeets from hollow trees where they nested. Many parakeets were shot for food and their feathers. In addition, farmers shot the parakeets to keep them from eating their seeds. What can you conclude from these observations about why the Carolina parakeet became extinct?
a.Extinction may be the result of several factors.
b.Extinction is always the result of human activity.
c.Extinction occurs when an organism adapts to changes in its environment.
d.Extinction can be reversed if conservation measures are immediately put in place.

Reece is putting in a circular pool in his backyard. Th
diameter of the pool is 36 ft. He has to build security
fencing around the pool. How much fencing will he
need to secure the pool?
Answer:
Step-by-step explanation:
we have to find out the circumference of the pool
C=2*3.14*r
d=36, r=18
C=2*3.14*18=113.04 ft
C=2*3.14*r
d=36, r=18
C=2*3.14*18=113.04 ft

Monique wants to bake a cake. She needs 2 1/8 cups of sugar, and 1 5/24 cups of flour. How many cups of ingredients will she use in all? *
Answer:
3 1/3 cups total
Step-by-step explanation:
Add together 2 1/8 cups and 1 5/24 cups. The LCD here is 24, and so we rewrite 2 1/8 cups as 2 3/24 cups.
Adding 2 3/24 cups and 1 5/24 cups, we get 3 8/24 cups,
which simplifies to 3 1/3 cups total

Answer:
if you want the area, then:
area = 35.625 in^2 or 35 5/8 in^2
if you want the perimeter, then:
perimeter = 30.05 in or 20 1/16 in
Step-by-step explanation:
area of left side triangle = 3.75(5)(0.5) = 9.375 in^2
middle rectangle = 5.5(3.75) = 20.625 in^2
right side triangle = 3(3.75)(0.5) = 5.625 in^2
total area = 35.625 in^2
right side^2 = (3.75)^2 + 3^2
right side = 4.80
perimeter = 5.5+4.8+8.5+5+6.25 = 30.05 in

What equation models the data in the table if d = number of days and c = cost?
Days
2
3
5
6
Cost
44
66
110
132
A. c = d + 22
B. c = 22d
C. d = 22c
D. c = d + 22d
Answer: B. c = 22d
I'm gonna go with c=22d
Step-by-step explanation: 22d
C = 22d is the correct answer because for every day the cost increases by 22 so two days mean the cost is equal to 22 (2)
...............................................................................................................................................
Answer:
The equation that models the data in the table is:
Step-by-step explanation:
The table that represent the days and cost is given by:
Days Cost
2 44
3 66
5 110
6 132
We see that the cost is a constant multiple of the number of days.
i.e. the equation is given by:
c=22d
i.e. the relationship is linear.
( Since, when d=2
we have: c=22×2=44
when d=3 we have:
c=22×3=66
and so on )
...............................................................................................................................................
You can see that 44/2 = 22
66/3 = 22
110/5 = 22
132/6 = 22
Then, the relation between C and d is a constant.
C/ d = 22
And you can model C as:
C = 22d.
This model tells that the cost equals 22 times the days.

In 2010, the population of a city was 161,000. From 2010 to 2015, the population grew by 8%. From 2015 to 2020, it fell by 6.7%. To the nearest whole number, by what percent did the city grow from 2010 to 2020.
Answer:
99%
Step-by-step explanation:
2010 population = 161,000
From 2010 to 2015, the population grew by 8%.
2010 to 2015 = 161,000 + (8% of 161,000)
= 161,000 + (0.08 * 161,000)
= 161,000 + 12,880
= 173,880
2010 to 2015 = 173,880
From 2015 to 2020, it fell by 6.7%
2015 to 2020 = 173,880 - (6.7% of 173,880)
= 173,880 - (0.067 * 173,880)
= 173,880 - 11,649.96
= 162,230.04
2015 to 2020 = 162,230.04
what percent did the city grow from 2010 to 2020.
= 161,000 / 162,230.04 × 100
= 0.9924179270374 × 100
= 99.241792703743
Approximately, 99% to the nearest whole number

(3x²-21x-24)take out the highest common factor
Answer:
x = 8 or x = -1 is the answer
Step-by-step explanation:
3x² - 21x -24
divide with 3
x² - 7x - 8
Factorizing,
x² + x - 8x - 8
x(x + 1) -8 (x + 1)
(x - 8) (x + 1)
x = 8,-1
During an local election the ratio of teens to adults who voted was 9.3. If 732 people voted how many were teens
Answer: 549
Step-by-step explanation:
Given
The ratio of teens to adults is 9:3
The total number of people who voted is 732
let 9x be the no of teens and 3x be the no of adults such that their ratio is 9:3
So, we can write
[tex]\Rightarrow 9x+3x=732\\\Rightarrow 12x=732\\\Rightarrow x=61[/tex]
No of the teens were [tex]9x=9\times 61=549[/tex]
