A test has a mean of 80 with a standard deviation of 4. Which of the following scores is within one standard deviation of the mean?
A
75
B
77
С
BO
D
90
E
09
Answer:
B
Step-by-step explanation:
Mathematically, we shall be using the z-score here
Z-score = (x-mean)/SD
From the question, mean = 80 and SD = 4
So we want to get the option in the question that has a z-score of 1 or below
Let’s look at 75
80-75 = 5 ( this is clearly above 1 standard deviation of 4)
For 77;
80 -77 = 3
This is less than the standard deviation of 4, meaning it is within 1 standard deviation of the mean
Option B) is correct.
Step-by-step explanation:
Given :
Mean [tex](\mu)[/tex] = 80
Standard Deviation [tex](\sigma)[/tex] = 4
Calculation :
We have to find the score that would be 1 deviation from the mean. Which means, the interval [tex](\mu-\sigma, \mu+\sigma)[/tex]
[tex]\mu-\sigma = 80-4=76[/tex]
[tex]\mu+\sigma =80+4=84[/tex]
The interval is (76,84)
Therefore, option B) is correct.

15. A music store sells a copy of a deluxe electric guitar for $295. This is $30 more
than 1/3 the cost of the actual deluxe guitar it is modeled after. What is the cost
of the deluxe electric guitar? Find your solution below. Type the code in exactly.
(ALL CAPS, NO SPACES). Example: If my answer was -76.1 l would type in KHGLB
Answer:
It costs $795
Step-by-step explanation:
$30 more than one half so you have to subtract 30 from 295 then that's 265 which is 1/3 of the acual price. So then you have to multiply 265 by 3 then you get $795.

A KIDZ society started a campaign "Plant the Plants " . They bought 750 saplings and wanted to arrange the maximum possible number of 750 saplings in a ground such that the number of rows is equal to the number of saplings in each row .Find the number of rows if 21 saplings were left out after the rearrangement .
Answer:
Three are 27 rows of saplings
Step-by-step explanation:
Since 21 saplings were left out of 750 saplings, the number of saplings arranged will be 750 -21 = 729 saplings
We were told that the number of saplings arranged per row is equal the number of rows
So let’s say the number of saplings arranged per row is x
Automatically, the number of rows too will be x
So the total number of saplings arranged will be;
x * x = x^2
This is equal to 729
x^2 = 729
x^2 = 27^2
Since power is equal, equate the base
This means that x = 27
f(x)=x^2+8x+15/2x^2+11x+5

Mario had 12 apples and gave away x apples. Luigi had 26 apples and gave away three times as many apples as Mario did. How many apples did Mario give away if they had the same number of apples left?
Answer:
7 Apples
Step-by-step explanation:
For this question, we can write expressions for Maria's apples and Luigi's apples and form an equation as they end up with the same amount.
Mario starts with 12 apples but gives away x number. This means Mario's final amount of apples can be represented as: 12-x
Similarly Luigi starts with 26 and gives away 3 times the amount of Mario. So the number he gave away can be represented as: 3x (3 times the number Mario gave away). Therefore we can represent Luigi's final number as: 26-3x
Since they both end up with the same number of apples, we can put these expressions equal to each other in an equation to solve for x (the number of apples Mario gave away):
Mario Luigi
12-x = 26-3x
12-x=26-3x
Now we just need to move the unknowns to one side and the other terms to the other, combine and solve:
12-x-12=26-12-3x
-x=14-3x
-x+3x=14-3x+3x
2x=14
2x/2=14/2
x=7
Mario gave away 7 apples.
Hope this helped!

Answer:
It takes 31 Pounds for UPS and FedEx to cost the same?
Step-by-step explanation:
The equation for the cost of a UPS shipping:
7 + .20x
to check the answer, you can do : 7 + (.20 x 31)
= $14.00
The cost for the cost of the PedEx shipping is:
5 + .30x
to check the answer, you can do : 5x + (.30 x 31)

You want to rent a car for a dayl It will cost the daily fee of $50 plus $0.35
per mile driven. Part A: Write an expression that shows the amount you will
pay for the car. Let m=the number of miles you drive for the day. Part B:
How much will you pay if you drive 80 miles?
Answer:
The payment for driving 80 miles is $78
Step-by-step explanation:
Mathematical model
Mathematical models are used in disciplines like natural sciences and engineering, among many others.
The data provided in the question allows building a model for the charges of the car rental, knowing there are two fees:
A fixed charge of $50
A variable charge or $0.35 per mile driven.
Part A
Using m as the number of miles driven for the day, the model for the payment for the car rental is:
P(m)=50+0.35m
Part B
Find the payment if the car is driven m=80 miles:
P(80)=50+0.35*80
P(80)=50+28=78
The payment for driving 80 miles is $78

x - y = 4 and x + y = 9
Answer:
5-1=4 and 5+4=9
Step-by-step explanation:
[tex]\huge\red{ƛƝƧƜЄƦ}[/tex]
System of Linear Equations entered :
[1] x - y = 4
[2] x + y = 9
Graphic Representation of the Equations :
y + x = 4 y + x = 9
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = -x + 9
// Plug this in for variable y in equation [1]
[1] x - (-x +9) = 4
[1] 2x = 13
// Solve equation [1] for the variable x
[1] 2x = 13
[1] x = 13/2
// By now we know this much :
x = 13/2 y = -x+9
// Use the x value to solve for y
y = -(13/2)+9 = 5/2
Solution :
{x,y} = {13/2,5/2}
