Answer:
His average grade would be 91.6... (or 92% if you're rounding up)
Step-by-step explanation:
Add 100, 96, 96, 88, 70, and 100 to get 550, then divide by 6 because there are 6 total grades.
If y varies directly as x and x=2 when y=−4, find y when x=−6.
Equation: ____________
Solution: y = ___________
Answer:
Equation: x × -2 = y
Solution: y = 12
Step-by-step explanation:
if (x = 2) is (y = -4) then (x = 1) is (y = -2) so if (x = -6) is (y = 12) if we follow the equation [x × -2 = y] which was found using the first set of variables and dividing each by 2.
1. The National Football League (NFL) has been finding new ways to reduce the risk of its players
getting concussions. For example, helmets have changed to keep players more safe. In the 2017-
2018 season, 190 athletes reported concussions out of 1700 total players. In the 2018-2018
season, 135 concussions were reported out of total 1650 players.
a. Make a two way table displaying this information.
TOTAL
b. Calculate the risk of a football player reporting a concussion in 2017-2018 and 2018-2019.
C. Find the absolute risk reduction.
Answer:
Reduced/depressed
courageously/daringly
Boost/inflate
Explanation:
The following statement displays the recommendation of National Football League's(NFL) rule to wear new and lighter helmets by the players to diminish the chances of head injury during collisions between players. However, it has led the players to play more brazenly and fearlessly that eventually may cause the expansion of the number of collisions suffered by NFL players due to the valiant behavior of the players. This equates the ratio and leading to no improvement in the reduction of injuries among them even after this rule.
Is 12n+60 equivalent to (n + 12) x 5 + 7n
Answer: 12n + 60
Step-by-step explanation:
So first you have to distribute the 5 in the parentheses.
(5)(n + 12) = 5n + 60
5n + 60 + 7n
Then add like terms.
12n + 60

Write an equation of the line below
Answer:
The equation of the line is:
[tex]y = 4x + 3[/tex]
Step-by-step explanation:
We know that the slope-intercept of line equation is
[tex]y = mx+b[/tex]
Where m is the slope and b is the y-intercept
Given the two points on a line
(0, 3)(-2, -5)Finding the slope between (0, 3) and (-2, -5)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:3\right),\:\left(x_2,\:y_2\right)=\left(-2,\:-5\right)[/tex]
[tex]m=\frac{-5-3}{-2-0}[/tex]
[tex]m=4[/tex]
We know that the y-intercept can be computed by setting x=0 and determining the corresponding y-value.
From the graph, it is clear:
at x = 0, y = 3
Thus, y-intercept = b = 3
Substituting m = 4 and b = 3 in the slope-intercept form of line equation
[tex]y = mx+b[/tex]
[tex]y = 4x + 3[/tex]
Therefore, the equation of the line is:
[tex]y = 4x + 3[/tex]
Meg ate 3/8 pound of blueberries. Jon ate 7/8 pound of blueberries. How many more pounds did Jon eat than
Meg?
Please help me
Answer:
4/8 more pounds
Step-by-step explanation:
7/8-3/8=4/8
Answer:
Jon ate 5/8 more pounds of blueberries than Meg.
Step-by-step explanation:
This is because the question is asking for the difference between how many blueberries Meg ate, and how many Jon ate. Therefore, we have to use subtraction.
7/8 - 3/8 = 5/8, therefore Jon ate 5/8 lb more than Meg.

8(-1)^4-3(-1)-7= ?
multiply 8 * -1= -8
so -8^4= 4096 that part is done.
now do -3 * -1 and get 3 because two neg. = posit.
so now the question should say
4096+3-7=?
4096+3= 4099-7= 4092
x=4092 i think unless that isnt what you are doing im srry if this is incorrect i tryed and i hope this is correct...again im srry if this is incorrect
Answer:
4
Step-by-step explanation:
8(-1)^4=8
-3(-1)=3
8+3-7=4

Find the values of the variables in each right triangle.
Answer:
x = 12
y = 16
Step-by-step explanation:
Use the Pythagoras Theorem on the left triangle.
[tex](Hypotenuse)2=(Base)^2+(Perpendicular)^2\\(x)^2=(7.2)^2+(9.6)^2\\x^2=51.84+92.16\\x^2=144\\x=\sqrt{144}\\x=12\\[/tex]
Now use the Pythagoras Theorem on the right triangle.
[tex](Hypotenuse)2=(Base)^2+(Perpendicular)^2\\(y)^2=(12.8)^2+(9.6)^2\\y^2=163.84+92.16\\y^2=256\\y=\sqrt{256}\\y=16\\[/tex]

Answer:
11/120Step-by-step explanation:
Red = 3Yellow = 5Blue = 2Possible options would be red or yellow as only two blue marbles.
Probability of 3 red:
3/10*2/9*1/8 = 1/120Probability of 3 yellow:
5/10*4/9*3/8 = 1/12Probability of same three is:

Answer:
[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]
Step-by-step explanation:
Given
The attachment
Required
Express the area as a sum of stores and parking lots
First, calculate the area of the stores
[tex]Store\ A = 25\ by\ 10[/tex]
[tex]Store\ B = 25\ by\ w[/tex]
[tex]Stores\ A\ and\ B = 25\ by\ 10 + w[/tex]
The area is then calculated as:
[tex]A_1 = 25 * (10 + w)[/tex]
Next, calculate the area of the parking lots
From the attachment, we have the following
[tex]Parking\ lot\ A = 13.5\ by\ 10[/tex]
[tex]Parking\ lot\ B = 13.5\ by\ w[/tex]
[tex]Parking\ lots\ A\ and\ B = 13.5\ by\ 10 + w[/tex]
The area is then calculated as:
[tex]A_2 = 13.5 * (10 + w)[/tex]
The area of the shopping centre is then calculated as:
[tex]Area = A_1 + A_2[/tex]
[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]

Please help!! I just need help with question 40!!
Answer:
a. 70%
b. 6 more times
c. subtract from 100% with percentages, subtract from 1 with decimals.
Step-by-step explanation:
a. To find the percentage of red and yellow, skip back the decimal point two times: 0.26 > 26% 0.04 > 4%
Add all of the percentages together to get 70%
b. To find how many times more students said red than yellow, divide yellow from red. It shows you how many times yellow can go into red, giving you the correct answer.
0.26 ÷ 0.04
26 ÷ 4
6
c. 14% + 26% + 40% + 4% = 84%
100% - 84%
16%
(do the same thing with decimals and pick your favorite method)
