Calculate the standard deviation. Variance = 107.76. Mean = 34.2
(Round up to the second decimal point.)
Answer:
The standard deviation is 10.38
Step-by-step explanation:
Given;
Variance, v = 107.76
mean, x = 34.2
The standard deviation is given by;
standard deviation = √variance
standard deviation = √107.76
standard deviation = 10.381
standard deviation = 10.38 (two decimal places)
Therefore, the standard deviation is 10.38
Find the slope of the line that passes through the two points given.
(-5,-4) and (-2,-3)
M=?
Answer:
[tex]m=\frac{1}{3}[/tex]
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply plug in the coordinates into the slope formula to find slope m:
[tex]m=\frac{-3-(-4)}{-2-(-5)}[/tex]
[tex]m=\frac{-3+4}{-2+5}[/tex]
[tex]m=\frac{1}{3}[/tex]
At midnight, the temperature was -8F. At noon, the temperature was 23F. Which expression represents the increase in temperature?
Can someone help please
ASAP
Answer:
see explanation
Step-by-step explanation:
using the tangent ratio in the right triangle
tan A = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{5}{11}[/tex] , then
∠ A = [tex]tan^{-1}[/tex] ( [tex]\frac{5}{11}[/tex] ) ≈ 24.4° ( to 1 decimal place )
tan C = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{11}{5}[/tex] , then
∠ C = [tex]tan^{-1}[/tex] ( [tex]\frac{11}{5}[/tex] ) ≈ 65.6° ( to 1 decimal place )
using Pythagoras' identity in the right triangle
the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is
AC² = AB² + BC² = 11² + 5² = 121 + 25 = 146 ( take square root of both sides )
AC = [tex]\sqrt{146}[/tex] ≈ 12.08 ( to 2 decimal places )
Eric, Peyton and Nathan go to a Chinese restaurant from lunch and order three different platters. Eric orders 2 portions of fried rice and 1 portion of chow mien. Peyton ordered 1 portion of fried rice, 1 portion of chow mien and 1 portion of sauteed broccoli. Nathan ordered 1 potion of sauteed broccoli and 2 portions of chow mien. Eric paid $5, Peyton paid $5.25 and Nathan paid $5.75 for their meals. How much does each item cost? *
Answer:
Fried rice is $2.25Chow mien is $2.75Sauteed broccoli is $0.25Step-by-step explanation:
Step 1: Create expressions
Assume that fried rice is x
Assume that chow mein is y
Assume that sauteed broccoli is z
Expression for Eric's order would be;
x + y = 5
Expression for Peyton's order would be;
x + y + z = 5.25
Expression for Nathan's order would be;
2y + z = 5.75
Step 2: Express in like terms
Now express z and x in terms of y so that we can solve for y;
2y + z = 5.75 x + y = 5
z = 5.75 - 2y x = 5 - y
Step 3: Solve variables
Solve for y
x + y + z = 5.25
(5 - y) + y + (5.75 -2y) = 5.25
5 + 5.75 - 2y = 5.25
10.75 - 2y = 5.25
2y = 10.75 - 5.25
2y = 5.5
y = $2.75
Solve for x;
x = 5 - y
= 5 - 2.75
= $2.25
Solve for z;
= 5.75 - 2y
= 5.75 - 2 * 2.25
= $0.25
Fried rice is $2.25
Chow mien is $2.75
Sauteed broccoli is $0.25

A blueprint for a building includes a rectangular room that measures 3 inches long and 7.5 inches wide The scale for the blueprint says that 1 inch on the blueprint is equivalent to 10 feet in the actual building. What are the dimensions of this rectangular room in the actual building?
3 · 7.5 = 22.5: 22.5 is the area of the building on the blueprint in inches
22.5 · 10 = 225 feet squared is the area of the building in real life.

Factor the expression completely.
8x -12
Answer:
x=1.5
Step-by-step explanation:
You divide 8 by 8 and then -12 by 8. And then you get x=-1.5 because 8 divided by 8 is zero and -12 divided by 8 is -1.5
Solve the equation. Then check your solution. 6 = negative 2 (10 n + 7)
n = - 1
Step-by-step explanation:Hi !
6 = - 2(10n + 7)
6 = - 20n - 14
20n = - 6 - 14
20n = - 20
n = - 20 : 20
n = - 1
6 = - 2(10×-1 + 7)
6 = - 2(-10 + 7)
6 = - 2(-3)
6 = 6 (true)
Good luck !
Answer:
n = -1 OR -1 = n
Step-by-step explanation:
6 = -2(10n +7)
First we remove the brackets by multiplying the inner numbers by -2
6 = -20n - 14
Then we add 14 on both sides
20 = -20n
We make n the subject and divide both sides by -20
n = -1 OR -1 = n

Answer:
24 units
Step-by-step explanation:
Perimeter of Polygon PQRSTU = sum of all its side lengths = PQ + QR + RS + ST + TU + PU
PQ = |-4 -(-2)| = 2 units
QR = |4 - 2| = 2 units
RS = |-2 - 2| = 4 units
ST = |2 -(-2)| = 4 units
TU = |2 -(-4)| = 6 units
PU = |4 - (-2)| = 6 units
Perimeter of Polygon PQRSTU = 2 + 2 + 4 + 4 + 6 + 6 = 24 units

Find the slope of the line that is perpendicular to the line that passes through the points (5,2) and (8,1)
Answer:
3
Step-by-step explanation:
The slope of the line passing through the points is
m = (y2-y1)/(x2-x1)
= ( 1-2)/(8-5)
= -1/3
The slope that is perpendicular is the negative reciprocal which is
- ( 1/(-1/3)
+ 3/1
The perpendicular slope is 3

Evaluate 8+3e when e=2
Answer:
14
Step-by-step explanation:
8 + 3e
e = 2
substitute in the given value
8 + 3(2)
simplify
8 + 6
14
Answer: 14
Step-by-step explanation: Here, we have the expression 8 + 3e
and we want to evaluate the expression when e = 2.
To evaluate an expression, we simply plug the
value of the variable into the expression, and solve.
So here, since e = 2, we have 8 + 3(2).
3(2) is equal to 6 so we have 8 + 6, which is equal 14.
It’s a good idea to get into the habit of using parentheses
when substituting numbers in for variables.
So the value of our expression when e = 2 is 14.

Customer pays $0.035 per minute for local calls, if the customer made 60 local calls that all lasted 3 minutes, how much will the customer pay?
The customer will pay $6.30 for the 60 local calls that all lasted 3 minutes.
To find out how much the customer will pay, we need to calculate the total cost for all the local calls.
Step 1: Calculate the total number of minutes for all the calls
Since the customer made 60 local calls and each call lasted 3 minutes, we can multiply 60 by 3 to get the total number of minutes.
60 calls * 3 minutes/call = 180 minutes
Step 2: Calculate the total cost for all the minutes
The customer pays $0.035 per minute for local calls. To find the total cost, we can multiply the total number of minutes by the cost per minute.
180 minutes * $0.035/minute = $6.30

Solving the equation
Answer:
y = 5
Step-by-step explanation:
Step 1: Write equation
-(4y + 2) - (-3y - 6) = -1
Step 2: Solve for y
Distribute: -4y - 2 + 3y + 6 = -1Combine like terms: -y + 4 = -1Subtract 4 on both sides: -y = -5Divide both sides by -1: y = 5Step 3: Check
Plug in y to verify it's a solution.
-(4(5) + 2) - (-3(5) - 6) = -1
-(20 + 2) - (-15 - 6) = -1
-22 - (-21) = -1
-22 + 21 = -1
