Alyssa missed 64 questions on her multiple choice science final and earned a grade of 68%. How many total questions were on the final exam?
Answer: 94 questions
Step-by-step explanation:
is %
----- = -----
of 100
64 68 68 is the percent Alyssa got correct on the exam.
----- = ----- 64 is the questions she got wrong of an unknown total.
x 100 x is the unknown variable. (the total questions on the test)
Cross multiply to get this: 64*100 = 68x
6400 = 68x (Divide by 68 on both sides)
You should get about 94.11 after dividing. You have to round as there cannot be have a question. It should be rounded to 94 questions. There are 94 questions and 64 were missed. To check your work, do 64/94. This should give you about 68% after rounding.

The graph shows the distribution of the number of text messages young adults send per day. The distribution is approximately Normal, with a mean of 128 messages and a standard deviation of 30 messages.
What percentage of young adults send more than 158 text messages per day?
16%
34%
68%
84%
Answer:
16%
Step-by-step explanation:
From the graph of distribution of the number of text messages
Young adults send more than 158 text messages per day is 16%
Given :
The distribution is approximately Normal, with a mean of 128 messages and a standard deviation of 30 messages.
Given 158 text messages . so x is 168
Now we find out z -score
[tex]z=\frac{x-mean}{standard\; deviation }[/tex]
Replace the values and find out z
[tex]z=\frac{158-128}{30} =1[/tex]
the value of z=1
Lets use the standard deviation table that gives area on the left
the table gives the percentage of adults less than 158
z-score value for z=1 is 0.8413
Now, percentage of young adults send more than 158 text messages
Percent (more than 158)=1- P(less than 158)=[tex]1-0.8413=0.1587[/tex]
To get percentage we multiply by 100
[tex]0.1587 \cdot 100= 15.87= 16[/tex]
Young adults send more than 158 text messages per day is 16%

1. Which of the following is the standard form of y = (x – 3)(x – 7)?
a. y = (x + 5)2 – 21
b. y = (x - 5)² - 4
c. y = (x + 5)2 - 4
d. y = (x – 5)2 + 28
A
B
9514 1404 393
Answer:
b. y = (x - 5)² - 4
Step-by-step explanation:
Here, we take "standard form" to mean "vertex form."
In the US, "standard form" would be ...
y = x² -10x +21
Vertex form is ...
y = (x -5)² -4 . . . . matches B

Manuela is having mugs made for a fundraiser. The Cup Company will make them for $4 each plus a $30 set-up charge. Mugs Are Us will make them for $4.50 each with no set-up charge. At what amount of mugs will the price be the same for both companies?
Answer:
The price will be the same for both companies at 60 mugs
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the rate of changeb is the fixed amountAssume that the number of mugs is x and the total cost of them is $y
∵ The Cup Company will make them for $4 each plus a $30
set-up charge
∴ The cost per mug = $4
∴ m = 4
∴ The fixed amount = $30
∴ b = 30
∵ x is the number of mugs
∵ y is the cost of them
→ Substitute the values of m and b in the form of the equation
∴ y = 4x + 30 ⇒ (1)
∵ Mugs Are Us will make them for $4.50 each with no set-up charge
∴ The cost per mug = $4.50
∴ m = 4.5
∴ The fixed amount = 0
∴ b = 0
∵ x is the number of mugs
∵ y is the cost of them
→ Substitute the values of m and b in the form of the equation
∴ y = 4.5x + 0
∴ y= 4.5x ⇒ (2)
∵ The price be the same for both companies
→ Equate the right sides of (1) and (2)
∴ 4.5x = 4x + 30
→ Subtract 4x from both sides
∵ 4.5x - 4x = 4x - 4x + 30
∴ 0.5x = 30
→ Divide both sides by 0.5
∴ x = 60
∴ The price will be the same for both companies at 60 mugs

The table gives a few x,y pairs of a line, what is x intercept
Answer:
Intersections of Linear Equations. The intersection of a line are the points where the line intersects, or crosses, the horizontal and vertical axes. The line shown on the graph intersects the two coordinate axes. The point where the line crosses the x-axis is called [x-intercept].
Step-by-step explanation:
heellpp me pls which equation can be used to solve the problem .60 percent of what number is 30 .
60x2 = 120
--------- this is a
30x2 = 60
30 divide 1 = 30 this is b
----------------
60 divide 1 = 60
60 divide 2 = 30
----------------- this is c
100 divide 2 = 50
100x2=200
---------- this is d
30x2 =60
NOTE pls vote and do not guess i will brainest you if right
Answer:
it is C because first let say the missing number is y and the equation is 60/100 x Y = 30 , we dived 60/100 for each and tht means ,60/100Y/60/100=30x100/60 ,we cancel the first by it self and Y will be alone ,Y=3000/60= 50. try my best.

Let U = {a, b, c, d, e, f, g}. Find the complement of the set A below.
A = {a, c, e, g}
Answer:
[tex]A' = \{b,d,f\}[/tex]
Step-by-step explanation:
Given
[tex]U = \{a, b, c, d, e, f, g\}[/tex]
[tex]A = \{a, c, e, g\}[/tex]
Required
Find the complement of A
The complement of A are elements in the universal set (U) but not in A.
In other words,
if [tex]A = \{a, c, e, g\}[/tex]
then A' are the elements other than a, c, e and g that are in the universal set
So
[tex]A' = \{b,d,f\}[/tex]
Where A' represents the complement

Answer:
discrete
Step-by-step explanation:
This graph is discrete. A discrete graph has separate values, which are represented by multiple unconnected points. In continuous graphs, the values are all connected to each other. If this graph was continuous, then we would see a line rather than separate dots. The graph can also not be neither continuous nor discreet because it passes the vertical line test, meaning that it is a function.

A store is hoping an advertising campaign will increase their number of customers by 30%. They currently have about 80 customers a day.
Answer:
There will be 104 customers a day, after advertising campaign
Step-by-step explanation:
Current number of customers in a day in shop = 80
After advertising campaign, the customers will increase = 30%
So, new customers will be:
We can find new customers by adding new 30% customers to the current 80 customers.
First find 30% of 80
[tex]30\% \ of \ 30\\=\frac{30}{100}*80\\=24[/tex]
Now, add 24 to current 80 customers.
Number of customers = 80+24 = 104
So, there will be 104 customers a day, after advertising campaign

Select the correct answer.
A triangle has side lengths of n, n - 3, and 2(n - 2). If the perimeter of the triangle is at least 37 units, what is the value of n?
Answer:
n = 11
Step-by-step explanation:
Perimeter = sum of all the sides
n + n - 3 + 2(n-2) = 37 units
n + n - 3 + 2n - 4 = 37 {Combine like terms}
n + n + 2n - 3 - 4 = 37
4n - 7 = 37
4n= 37 + 7
4n = 44
n = 44/4
n = 11
