Explanation: For example of no solution 6=5 as you can tell 6 is not the same to 5 so there is no solution. More examples are 2=3, 8=10, and 1=0. For infinite solutions examples are 2=2, 7=7, and 10=10 as we can see 2 does equal 2 and 7 equals 7 which makes it true and infinite.

(1) Is climate change causing more severe storms? In a 2017 pre-Hurricane Irma
survey, 486 out of 1,080 adults answered in the affirmative. In a 2017 post-
Hurricane Irma survey, 546 out of 1,050 answered affirmatively. Establish a 90%
Confidence interval estimate of the difference (pre- minus post-hurricane) between
the proportions of adults pre-Hurricane Irma and post-Hurricane Irma who believe
climate change is causing more severe storms.
Answers
Answer:
90% Confidence Interval for difference in Proportion = (-0.106, -0.034)
Step-by-step explanation:
The formula for difference in proportions is given as:
p1 - p2 ± z × √p1(1 - p1)/n1 + p2(1 - p2)/n2
p = x/n
In a 2017 pre-Hurricane Irma
survey, 486 out of 1,080 adults answered in the affirmative.
x1 = 486
n1 = 1080
p1 = 486/1080 = 0.45
In a 2017 post- Hurricane Irma survey, 546 out of 1,050 answered affirmatively.
x2 = 546
n2 = 1050
p2 = 546/1050 = 0.52
Z score for 90% confidence interval = 1.645
Confidence Interval
=0.45 - 0.52 ± 1.645 × √0.45 (1 - 0.45)/1080 + 0.52(1 - 0.52)/1050
= -0.07 ± 1.645 × √0.0002291667 + 0.0002377143
=-0.07 ± 1.645 × √(0.000466881)
= -0.07 ± 1.645 × 0.0216074293
= -0.07 ± 0.0355442212
Confidence Interval
-0.07 - 0.0355442212
= 0.1055442212
Approximately = -0.106
-0.07 + 0.0355442212
= -0.0344557788
Approximately = -0.034
Therefore, 90% Confidence Interval for difference in Proportion = (-0.106, -0.034)

A candy company can sell fruit gums in rectangular boxes or in cylindrical tubes. Each box is 8 cm by 3 cm by 7 cm. Each cylinder has radius 3 cm and height 6 cm. The company wants the packaging that uses less material. Which packaging should the company choose? Justify your choice.
Answers
Answer:
i. The company should use the cylindrical tubes.
ii. This is because the surface area of the cylindrical tubes, A' = 169.65 cm² is less than the surface area of the rectangular box, A = 202 cm²
Step-by-step explanation:
i, Which packaging should the company choose?
The packaging that uses less material is the one with the least surface area. So, we find the surface area of each material.
For the rectangular box, the surface area, A = 2(lb + lh + bh) where l = length, b = breadth and h = height. Since each box is 8 cm by 3 cm by 7 cm,l = 8 cm, b = 3cm and h = 7cm.
So, ,A = 2(lb + lh + bh)
,A = 2( 8 cm × 3 cm + 8 cm × 7 cm + 3 cm × 7cm)
A = 2(24cm + 56 cm + 21cm)
A = 2(101 cm²)
A = 202 cm²
For the cylindrical tube, the surface area, A' = 2πr(r + h) where r = radius of cylinder and h = height of cylinder.
Since each cylinder has radius 3 cm and height 6 cm, r = 3cm and h = 6 cm.
So, A' = 2πr(r + h)
A' = 2π(3 cm)(3 cm + 6cm)
A' = (6π cm)(9 cm)
A' = 54π cm²
A' = 169.65 cm²
Since the surface area of the cylindrical tubes, A' = 169.65 cm² is less than the surface area of the rectangular box, A = 202 cm²
The company should use the cylindrical tubes.
ii. Justify your choice.
This is because the surface area of the cylindrical tubes, A' = 169.65 cm² is less than the surface area of the rectangular box, A = 202 cm²

Select the correct answer. Which inequality is graphed on the coordinate plane?
A. y < 4x + 2
B. y > 4x + 2
C. y ≤ 1/4x +2
D. y ≥ 4x + 2
E. y ≤ 4x + 2
Answers
Answer:
y > 4x + 2
Step-by-step explanation:
Y is above the line so the value has to be greater than the line (or equal to, possibly). So it represents > or ≥
A dotted/dashed line is non-inclusive, so it represents < or >.
Since it is both above the line AND non-inclusive, we would use this sign:
>

Will arrived at his mother's office at 11:00am. It took him 30 mins to walk from his home to the mall. Will was in the mall for 45 mins. It took will 15 mins to walk from the mall to the office. At what time did will leave home?
Answers
Answer: 9:30 am
Step-by-step explanation:
To solve this question, add up the time that Will spent walking from his home to the mall and then the length of time he spent in the mall and then the amount of time it took him to walk from the mall to the office:
= 30 + 45 + 15
= 1 hr 30 mins
Then deduct this number from 11:00 am to find out when he left home:
= 11 am - 1 hr 30 mins
= 9:30 am

hello : here is an solution
Find the constant of proportionality (k). Using the value for k, enter an equation in the form of y = kx.
Answers
Answer:
k = 4, y = 4x
Step-by-step explanation:
From the question, we get the ratio of :
x : y = 1 : 4
Two variables are proportional to each other if their ration is constant. The constant value is denoted by 'k' and is called as constant of proportionality.
In the question, the two variables are :
x = glasses of lemonade
y = lemons used
From the question, the ratio of y is to x is given by :
y : x is 24 : 6 = 4 : 1 or 24/6 = 4
32 : 8 = 4 : 1 or 32/8 = 4
28 : 7 = 4 : 1 or 28/7 = 4
8 : 2 = 4 : 1 or 8/2 = 4
16 : 4 = 4 : 1 or 16/4 = 4
So here the constant is 4 . Therefore, the constant of proportionality, k is 4.
So we can write the equation as :
y = kx
or y = 4x

PART I: find the similarity ratio by taking the cube root of each volume. Show your work.
PART II: Use your answer from Part I to find the ratio of the surface areas. Show your work.
PART III: Set up a proportion and solve to find the surface area of a larger solid.
Answers
Answer:
2535 cm²
Step-by-step explanation:
Part 1
Cube root the ratio to find the length factor as volume factor = length factor³
∛512 : ∛2197 = 8 : 13
Part 2
Square the ration as area factor = length factor²
8² : 13² = 64 : 169
Part 3
Apply the ratio
64 : 169
960 / 64 = 15
15 x 169 = 2535

Answers
Given:
[tex]7-2y>3y+13[/tex]
To find:
The whether the value [tex]y=-1[/tex] is a solution of the given inequality or not.
Solution:
We have,
[tex]7-2y>3y+13[/tex]
It can be rewritten as
[tex]-2y-3y>13-7[/tex]
[tex]-5y>6[/tex]
Divide both sides by -5 and change the inequality sign.
[tex]y<\dfrac{6}{-5}[/tex]
[tex]y<-1.2[/tex]
All the value of y less -1.2 are the solutions of the given inequality but -1 is greater than -1.2.
[tex]-1>-1.2[/tex]
Therefore, [tex]y=-1[/tex] is not a solution of the given inequality.
