Find the midpoint of the segment with the given endpoints. (4,-4) and (7,-1)
Answer:
The midpoint is (5.5 , - 2.5)
Step-by-step explanation:
To get the midpoint of the line segment, we use the midpoint formula
We have this as follows;
(x,y) = (x1 + x2)/2 , (y1 + y2)/2
(x1,y1) = (4,-4)
(x2,y2) = (7,-1)
We have;
(x,y) = (4+7)/2 , (-4-1)/2
(x,y) = 11/2 , -5/2
(x,y) = (5.5, -2.5)

What is the Venn diagram?A Venn diagram is a diagram that helps us visualize the logical relationship between sets and their elements and helps us solve examples based on these sets. A Venn diagram typically uses intersecting and non-intersecting circles (although other closed figures like squares may be used) to denote the relationship between sets.
Let Math=M, Science=S and English=E
n(M)+n(S)+n(E)=1/2 (n(M∩S)+n(S∩E)+n(E∩M)
Let the number of students who study only one subject be x.
Let the number of students who study only two subjects be x/2.
n(M∩S∩E)=20
n(M∩S)+n(S∩E)+n(E∩M)=80
∪=x/2+80
∪=x+ x/2+20
Now, x/2+80 = x+ x/2+20
⇒ x=60
So, ∪=x/2+80 =110
Therefore, the total number of students in the survey is 110 students.

Answer:
$13.50
Step-by-step explanation:
Hardcover Books = $18.25 each
Softcover Books = $5 each
She bought 2 hardcover and 2 softcover.
Hardcover: $18.25 + $18.25 = $36.50
We already know what 2 softcover books cost ($10)
No add those both together.
$36.50 + $10.00 = $46.50
She gives the clerk $60
$20 + $20 = 40
$20 + $20 = 40
$20 - $6.50 = $13.50

Victoria and Max are making friendship necklaces. They need 2 feet of string and 5 glass beads
to make each necklace.
• Victoria has $15 to purchase the string.
• A roll of 120 feet of string costs $5.99.
• Max has $36 to purchase the glass beads.
• A pack of 50 glass beads costs $3.69
Part B
If Victoria buys as much string as she can, and Max buys as many beads as he can, how much
money will each have left over? Assume there is no tax. Show your work or explain your
answer.
Answer:
Victoria will have 3 dollars left and max wil have 2.79 cents left
Step-by-step explanation:
3.69 x 10 is 36.9 and max only has 36 dollars so change the 10 to a 9 and then subtract 36 - 33.21 which is the answer for 3.69x9. and victoria can only buy 2 120ft of string which would be 11. 98 cents
Mateo paid $6.00 for 12 doughnuts. Enter an equation to represent the relationship between the total cost, c, in dollars, and the number of doughnuts, n.
Answer:
If a dozen donuts costs 6.00 dollars, one donut costs half a dollar.
0.50 x n = c
Take the cost of a single donut, times it by the number of donuts your getting, and then you will know the cost.

the total sale was neither a profit nor loss , 0%
Step-by-step explanation:
1st table :
100%-> 9900
110%-> 10890
10890-9900=990(earned)

Orchid wants to retile her bathroom floor, which has an area of 40 square feet. She is deciding between two types of custom tiles. The square tile is One-half foot by One-half foot and costs $0.45 per tile. The rectangular tile is 2 feet by One-fourth foot and costs $0.80 per tile.
Answer:
b. She should choose the rectangular tiles because the total cost will be $8 less.
Step-by-step explanation:
Which tile should Orchid choose to minimize costs? Explain.
a. She should choose the square tiles because the total cost will be $8 less.
b. She should choose the rectangular tiles because the total cost will be $8 less.
c. She should choose the square tiles because the total cost will be $14 less.
d. She should choose the rectangular tiles because the total cost will be $14 less.
Area of a square tile = 1/2 × 1/2
= 1/4
= 0.25 square feet
Area of rectangular tile = 2 × 1/4
= 2/4
= 0.5 square feet
Number of square tile needed = Area of the bathroom floor / Area of the square tile
= 40 square feet / 0.25 square feet
= 160
Number of square tile needed = 160
Cost of square tile needed = number of tiles × cost per tile
= 160 × $0.45
= $72
Cost of square tile needed = $72
Number of rectangular tile needed = Area of the bathroom floor / Area of the rectangular tile
= 40 square feet / 0.5 square feet
= 80
Number of rectangular tile needed = 80
Cost of rectangular tile needed = number of tiles × cost per tile
= 80 × $0.80
= $64
Cost of rectangular tile needed = $64
Cost of square tile needed = $72
Cost of rectangular tile needed = $64

Answer:
Gateway Arch is [tex]292.46[/tex] feet tall

As we know,
the horizontal distance from the gate of the Arch to the bench [tex]= 724[/tex] feet
The angle of elevation is [tex]22[/tex] degree
Let H be the height of the gate be "H"
Tanθ= Perpendicular/Base
Substituting the given values in above equation, we get -
[tex]tan 22 = \frac{H}{724} \\H = 724 * tan 22\\H = 724 * 0.404\\H = 292.46[/tex]feet

For which of the following conditions is it not appropriate to assume that the sampling distribution of the sample mean is approximately normal?

C

A random sample of 75 taken from a population distribution that is skewed to the left
D
A random sample of 100 taken from a population that is uniform
Answer:
C
Step-by-step explanation:
Using the Central Limit Theorem, it is found that the option in which is it not appropriate to assume that the sampling distribution of the sample mean is approximately normal is:
C) A random sample of 10 taken from a population distribution that is skewed to the right
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.In option C, there is an skewed variable and a sample size less than 30, hence, the Central Limit Theorem is not applicable.
