Calculate the mean for the following data set:
Data Set = 2, 9, 10, 4, 8, 4, 12
Answer:
7
Step-by-step explanation:
Mean, also referred to as average, is evaluated by dividing the sum of the data by the amount of data.
2+9+10+4+8+4+12 = 49
Dividing 49 by the amount of data, 7
49/7 = 7
Answer:
7
Step-by-step explanation:
add all 2, 4, 4, 8, 9, 10, 12
divide some by number of data set 7

(x − 5)^2 = x^2 − 25
Answer:
x=5
Step-by-step explanation:
x^2+25-10x = x^2-25
-x^2 -x^2
25-10x = -25
-25 -25
-10x = -50
x=5
lets check
(5-5)^2 = 5^2-25
0^2 = 25-25
0 = 0
Answer:
x = 5
Step-by-step explanation:
(x - 5)^2 = (x - 5) (x - 5) =
x^2 -10x + 25 = x^2 - 25
x^2 - x^2 - 10x + 25 = - 25 (x^2 - x^2 = 0)
- 10x + 25 = - 25
- 10x = - 25 - 25
x = - 50/- 10
x = 5
A triangle has angle measures
x+15, 3x-35, and 4x.
What type of triangle is it? Be as specific as possible. Justify your answer.
3b- 4/2 = c , for b
please explain the steps
Answer:
b = c/3 + 2/3
Step-by-step explanation:
3b - 4/2 = c
the goal is to have b all by itself on one side of the equals sign.
start by moving the fraction over to where c is by adding.
3b = c + 4/2
adding -4/2 and +4/2 together makes it a 0 on the b side so there's no need to write anything in that space anymore.
Now 3b are next to each other which means they are multiplying. To move 3 we need to do the opposite (divide by 3 on both sides of the equal sign)
b = c/3 + 2/3
notice I divided both c and 4/2 by 3. 4/2 = 2 so I changed it to 2, then divided by 3
Find the x- and y-intercepts of the graph of — 7x + 8y = 40. State your answers as
whole numbers or as improper fractions in simplest form.
Answer:
x-intercept is (40/7, 0) and y-intercept is (0, 5)
Step-by-step explanation:
x-intercept ==> y-coordinate is 0 ==> y=0
y-intercept ==> x-coordinate is 0 ==> x=0
because the function is 7x + 8y = 40
when y = 0 ==> 7x = 40 ==> x = 40/7
so the x-intercept is (40/7, 0)
when x = 0 ==> 8y = 40 ==> y = 5
so the y-intercept is (0,5)
Question 7 = 2 Points

Samantha has $600 to spend at a bicycle store for some new gear and biking outfits.
Assume all prices listed include tax,
• She buys a new bicycle for $399,95
• She buys 3 bicycle reflectors for $7.01 each and a pair of bike gloves for $34.06.
• She plans to spend some or all of the money she has left to buy new bilding outfits
for $75,88 each
Write and solve an inequality which can be used to determine w, the number of
outfits Samantha can purchase while staying within her budget
Answer:
See belowStep-by-step explanation:
The budget is $600.
Samantha spends the following amount:
399.95 + 3*7.01 + 34.06 = 455.04Now, she plans to buy w outfits which cost $75.88 each.
The inequality for this is:
455.04 + 75.88w ≤ 600Solving this we get:
75.88w ≤ 600 - 455.0475.88w ≤ 144.96w ≤ 144.96 / 75.88w ≤ 1.91w = 1 is the only integer solution greater than zero
A newborn baby has about 26,000,000,000 cells. An adult has about 4.94 x 10^*13 cells. How many times as
many cells does an adult have than a newborn? Enter your answer in scientific notation.
An adult has about =
times more cells than a newbom baby.
New born = 2.6 × 10¹⁰ cells.
Adult = 4.94 × 10¹³ cells.
How many times more = adult cells ÷ newborn cells
= 4.94 × 10¹³ cells ÷ 2.6 × 10¹⁰ cells
= 1.9 × 10³ cells
∴ adults have about 1.9 × 10³ more cells than newborn babies.

Answer:
slope is -2/3
Step-by-step explanation:
y = mx+b
m = slope
b = y-intercept
given: y = -2/3x
in this case we don't have a b so make it an automatic 0
now we have y = -2/3x +0
slope is m, so our slope is -2/3
Carmen wants to buy a pair of shoes that regularly costs $78. Today, the shoes are on sale for 60% of the original price. How much will Carmen have to pay for the shoes?
Answer:
31.2
Step-by-step explanation:
Change 60% into 0.6 by moving the decimal 2 points to the left
Multiply 0.6 by 78 to get 46.8
Subtract 78 and 46.8 to get 31.2 which is your answer

Find the value of x with all work, parallel lines and transversal lines
Answer: no idea
Step-by-step explanation:
Find the equation in slope-intercept form of the line parallel to y = 4x + 23 and passes through the point (2,3).
Answer: y=4x-5
Step-by-step explanation:
The slope of y=4x+23 is:4 m=4
The parallel line needs to have the same slope of 4
Solve it using the "point-slope" equation of a line: y− y1 = 2(x − x1)
substitute or put in the point (2,3):
y − (3) = 4(x − 2)
y - 3 = 4x - 8
put it in slope intercept form y = mx + b
y = 4x − 5

Answer: 3.5 years
Step-by-step explanation: Let A be the salaries earned from company A for x years and B for company B for the same years.
A = 31000 + n*3000
B = 38000 + n*1000
To find the case where A = b, set them to each other and solve for n, the number of years.
31000 + n*3000 = 38000 + n*1000
2000n = 7000
n = (7000/2000) = 3.5 years.

The rate of change is also known as the slope or rise / run.
Slope Formula: (y2 - y1) / (x2 - x1)
First, we'll need two points that are on the line. You can choose any two points you want, as long as they are on the line.
Point 1 = (0, 1)
Point 2 = (-2, -3)
Then, we'll plug the two points into the formula and solve for the slope.
(-3 - 1) / (-2 - 0)
(-4) / (-2)
2
The rate of change of this line is 2.
Hope this helps!! :)
Answer: the rate of change is 2
Step-by-step explanation:
In a system of linear equations, the two equations have the same slope. Describe the possible solutions to the systems
