José represents the linear function f(x) = 5x – 7 with words.
Multiply each element in the domain by negative 7 and add 5.
Correct his error.
Answer:
-2
Step-by-step explanation:
The correct statement that Jose is supposed to have written is that multiply each element in the domain by 5 and subtract 7
Given the linear function written by Jose expressed as f(x) = 5x - 7
Note that the expression is in form of a linear equation y = mx + b where:
x is the input value known as the domain
We are to write the function f(x) = 5x - 7 in words.
Let the domain variable be x
5x means that we are to multiply each element in the domain 5
For 5x - 7, we are to multiply each element in the domain by 5 and subtract 7.
The correct statement that Jose is supposed to have written is that multiply each element in the domain by 5 and subtract 7

At a financial conference, the 750 attendees were given the choice of turkey, ham, both, or neither on the sandwich in their sack lunch. Eighty-five of the attendees chose neither and 200 chose both. If a total of 400 people had ham on their sandwiches, use the Venn diagram below to determine how many people had only turkey on their sandwich.
750
665
350
265
Answer:
265
Step-by-step explanation:
All values should add up to 750
85 + 400 + x = 750
485 + x = 750
x = 265
Number of people had only turkey on their sandwich from the given Venn diagram is equals to 265.
What is Venn diagram?
" Venn diagram is defined as pictorial representation of set of data using circles and rectangle in logical form to represent the relation between the given sets."
According to the question,
From the given Venn diagram,
Total number of attendees = 750
Number of attendees choose neither sandwich = 85
Number of attendees choose both turkey and Ham sandwich= 200
Total number of attendees choose ham sandwich = 400
'x' represents the number of attendees choose only turkey sandwich
As per condition of the sets in the Venn diagram we get,
[tex]400 + 85 + x = 750\\\\\implies 485 + x=750\\\\\implies x = 750-485\\\\\implies x = 265[/tex]
Hence, number of people had only turkey on their sandwich from the given Venn diagram is equals to 265.

PLEASE HELP ME I REALLY NEED IT
Answer:
x = 0
Step-by-step explanation:
when you plug in x as 0, you would have
0 + 3y = 12
0 = 8 - 2y
3y = 12
3y divided by 3 is y
12 divided by 3 is 4
y = 4
plug y in for the second equation
0 = 8 - 2(4)
0 = 8 - 8
this is why x = 0

Answer:
[tex]\sqrt{89}[/tex]
Step-by-step explanation:
distance = [tex]\sqrt{(x_{2}- x_{1})^{2} + { (y_{2} - y_{2} } ){^2} }[/tex]
Let:
(x₁ , y₁) = (0 , 5)
(x₂ , y₂) = (8 , 0)
Plug in the corresponding numbers to the corresponding variables:
Remember to follow PEMDAS. Solve the parenthesis first:
distance = [tex]\sqrt{(8- 0)^{2} + { (0 - 5 } ){^2} }[/tex]
distance = [tex]\sqrt{(8)^2 + (-5)^2}[/tex]
Solve for the powers next:
distance = [tex]\sqrt{(8)^2 + (-5)^2}[/tex]
distance = [tex]\sqrt{64 + 25}[/tex]
Simplify:
distance = [tex]\sqrt{64 + 25}[/tex]
distance = [tex]\sqrt{89}[/tex]

140
Answer: 140 m3
Step-by-step explanation:
Multiply the area of the trapezoid face by the length .
Since the area is 20, you multiply it by 7 to get 140
Answer:
140 m^3
Step-by-step explanation:
This is a prism with a trapezoid base.
The volume if a prism is
V = (area of base) * height
The base is the trapezoid in the front face. The height is the distance between bases which is 7 m.
area of trapezoid = (b1 + b2)h/2
In the area of the trapezoid, h is the height of the trapezoid which is the distance between parallel bases. It is 4 m in this case.
V = (area of base) * (height of trapezoid)
V = (8 m + 2 m)(4 m)/2 * 7 m
V = 20 m^2 * 7 m^2
V = 140 m^3
How can you use the mean absolute deviation of two
data sets to compare them?
Answer:
The mean absolute deviation tells you how spread out or how clustered around the mean a set of data is. This is the variation in the data. To compare sets, a higher mean absolute deviation indicates that the data points are more spread out from the mean. A lower mean absolute deviation indicates data points are more clustered around the mean.
Answer:
Sample Answer: The mean absolute deviation tells you how spread out or how clustered around the mean a set of data is. This is the variation in the data. To compare sets, a higher mean absolute deviation indicates that the data points are more spread out from the mean. A lower mean absolute deviation indicates data points are more clustered around the mean.

The mean absolute value is a measure of variation and indicates the spread of the data.

OA) 65 mi. per day
OB) 73 mi. per day
OC) 82 mi. per day

Answer:73
Step-by-step explanation:
The MEAN in math means you add all of the numbers together
60 plus 65 plus 73 plus 82 plus 85 = 365
then you divide how many numbers there are and there is 5 numbers so you divide.
365 divided by 5 equals 73

Step-by-step explanation:
1.
SA and V of 3x4x5 right rectangular prism.
Three pairs of faces, 3×4, 4×5, 3×5, so area
SA = 2(3×4 + 4×5 + 3×5) = 94 sq ft
V = L×W×H = 3×4×5 = 60 cubic ft
Answer: D. SA 94 sq ft, V 60 cu ft
2. Right triangular prism, base legs 3x4, height 7
Two triangular faces, combined area 2×(1/2)×3×4=12, and three rectangular faces, 3x7, 4x7 and 5x7
SA = 12 + 7(3+4+5) = 8(12) = 96
Volume is area of base times height, so (1/2)(3)(4)(7)=42.
Answer: I. SA 96 sq cm, V 42 cu cm

barn help me please
48π cm^3
Step-by-step explanation:
The formula for the volume of a cone is...
[tex]V=\frac{1}{3}\pi r^2h[/tex]
We can plug everything we know from the photo into the equation, but note that the picture gives us the diameter, which is 8, instead of the radius. The radius is half of the diameter, so the radius will be 4. Also we will be leaving pi as it is, instead of changing it to 3.14.
[tex]V=\frac{1}{3}*(\pi *4*4*9)[/tex]
[tex]V=\frac{1}{3}*(144\pi )[/tex]
V = 48π
The paper cone can hold 48π cubic centimeters of water.
Answer:
Step-by-step explanation:
d = 8 cm
r =8/2 = 4 cm
h = 9cm
Volume of cone = (1/3)πr²h
[tex]=\frac{1}{3}\pi *4*4*9\\[/tex]
= 4*4*3*π
= 48π cubic centimeteres

For f(x) = x^2 and g(x) = (x-5)^2 in which direction and by how many units should f(x) be shifted to obtain g(x)?
A.) up 5 units
B.) down 5 units
C.) left 5 units
D.) right 5 units
Answer:
D
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
Thus
(x - 5)² represents a shift of f(x) to the right of 5 units
