C
Step-by-step explanation:
x+x-1-1-1-1-1-1-1 = -x-x-x+1+1+1+1+1+1+1+1+1
2x-7 = -3x +9
5x - 7 = 9
5x = 16
x = 16/5
x= 3⅕

A marketing consultant wants to estimate the true proportion of all residents that live near a certain mall who make at least one purchase at the mall in the past week. He stands at a mall exit for two hours on a weekday afternoon and flips a coin each time a shopper leaves. If the coin comes up heads, he asks them if they have made any purchases during this visit. After two hours, he has 132 responses, 104 of whom made a purchase. Which condition for constructing a confidence interval for a proportion has the consultant failed to satisfy
Options :
a) np ≥ 10
b) n(1-p ) ≥ 10
c) n ≥ 30
d) The data is a random sample from the population of interest.
e) The sample is less than 10% of the population.
Answer:
d) The data is a random sample from the population of interest.
Step-by-step explanation:
To construct a confidence interval, certain conditions has to be met before the validity of the confidence interval could be established, this include a sufficiently large sample, (n > 30)
n (1- p) ≥ 10 = 132(1 - 104/132) = 132 * 0.2121 = 28 (condition is met).
The condition which the data fail to meet is the randomization condition, whereby the method of selection isn't completely random with some participants having a much more chances of being selected ahead of others. A better random sampling procedure should be is d in the population to draw out the required sample.

Solve for X. Please help ASAP. I have no idea how to do this, and it’s due soon!!
Answer:
x = 126°
Step-by-step explanation:
x and 54° are same side interior angles and their sum is 180°
x + 54° = 180°
subtract 54° from each side of the equation:
x = 126°
If each of the cubes in a Rubik's Cube represented 1 cubic inch, what would be the volume of the Rubik's Cube?
Answer:
The volume of the Rubik's Cube is 27 in^3
Step-by-step explanation:
Each face of a Rubik's Cube has 3x3 cubes, then each face has 9 small cubes.
We can think of a Rubik's Cube as 3 pieces, such that each piece has 9 small cubes on it, and the 3 pieces are: Front side, middle part, back part.
Then the total number of small cubes on a Rubik's cube is 9*3 = 27 small cubes.
Now we know that each one of these small cubes has a volume of 1 in^3
Then the volume of 27 of these cubes is 27 times the volume of a single smaller cube, then the volume of the Rubik's Cube is:
V = 27*( 1 in^3) = 27 in^3

Pls solve I will mark brainliest!
It's the fourth answer, y=10. This is because the line is a straigh line is 180 degrees, which is shown in the photo. You have to take away 120 degrees (the angle is the same on both sides) which would leave you with 60. Then, thats the sum of the angle, but since were solving for y, you have to divide 60 by 6, which gives you your answer, 10. Hope this helps, if you need anything else you can message me!

Answer:
75 students
Step-by-step explanation:
500 students x 0.25 (25%) = 125 play baseball
500 students x 0.10 (10%) = 50 play soccer
125 who play baseball - 50 who play soccer = 75 more students who play baseball
Answer:
75 students because
since there are 500 students..
10% of 500 is 50
25% of 500 is 125
125-50=75

The polygons to the right are similar. Find the value of each variable
Answer:
y = 7
x = 24
Step-by-step explanation:
When two triangles are similar, the ratio of their corresponding sides are equal
For the bigger triangle we have a total 48; so for the smaller we have x
For the bigger, we have 14, so for the smaller, we have y
Mathematically;
25/x = 50/48
x * 50 = 25 * 48
x = (25 * 48)/50
x = 24
For y;
25/y = 50/14
y = (25 * 14)/50
y = 7
The rectangle below has an area of 70 square meters.
Find the dimensions of the rectangle.
(x - 11)
(x - 8)
Answer:
The side lengths are 10 by 7
Step-by-step explanation:
The area of a rectangle is
A = l*w
70 = (x - 11)(x - 8)
FOIL
70 = x^2 -8x-11x+88
Combine like terms
70 = x^2 -19x +88
Subtract 70 from each side
0 = x^2 -19x +88-70
0 = x^2 -19x+18
Factor
What number multiplies to 18 and adds to -19
-18*-1 =18
-18-1 = -19
0=(x-18)(x-1)
Using the zero product property
x-18=0 x-1=0
x=18 x=1
But x cannot x=1 because then the side lengths would be negative
x-18 = 10
x-11 = 7
The side lengths are 10 by 7
Amanda slept for 1/3 of the day. She played with her friends for 1/5 of the day. She spent the rest of the day working on a school project. What fraction of the day did she spend working on her project
Answer:
Amanda spent 7/15 of the day working on her project.
Step-by-step explanation:
1/3 x 5/5 = 5/15 1/5 x 3/3 = 3/15 5/15 + 3/15 = 8/15 15/15 - 8/15 = 7/15When Anita planted a large bush in her garden, it was 5 feet tall. Now it is 40% taller. How tall is the bush now?
Answer:
7 feet
Step-by-step explanation:
the new height of the bush can be represented in percentage form as 100% + 40% = 140% = 1.40
1.40 x 5 = 7 feet
Method 2
find 40% of 5 feet
0.4 x 5 = 2
Add 5 + 2 = 7 feet
