Answer:
At least 98 is needed in the 5th game
Step-by-step explanation:
The missing parameters are:
[tex]Game\ 1 = 95[/tex]
[tex]Game\ 2 = 91[/tex]
[tex]Game\ 3 = 77[/tex]
[tex]Game\ 4 =89[/tex]
[tex]Mean = 90[/tex] at least
Required
The score in game 5 to make you advance
Mean is calculated as:
[tex]Mean = \frac{\sum x}{n}[/tex]
So, we have:
[tex]Mean = \frac{95 + 91 + 77 + 89 + Game\ 5}{5}[/tex]
[tex]Mean = \frac{352 + Game\ 5}{5}[/tex]
The mean must be at least 90.
So, we have:
[tex]\frac{352 + Game\ 5}{5} \ge 90[/tex]
Multiply both sides by 5
[tex]5 * \frac{352 + Game\ 5}{5} \ge 90 * 5[/tex]
[tex]352 + Game\ 5 \ge 450[/tex]
Make Game 5 the subject
[tex]Game\ 5 \ge450 - 352[/tex]
[tex]Game\ 5 \ge 98[/tex]
At least 98 is needed in the 5th game
To solve for n, I should do what to both sides of the equation? n - 8 = 13
A. Add 8 to both sides of the equation.
B. Subtract 8 from both sides of the equation.
C. Subtract 13 from both sides of the equation.
D. Add 13 to both sides of the equation.
Ty can jump rope at a rate of 6 jumps every 3 seconds. What is Ty's jump-roping rate in
jumos per minute? Explain your thinking.
Answer:
120 Jumps per Minute
Step-by-step explanation:
3 Seconds per jump
So we do 60 (seconds in a minute) / 3 (seconds)
We get 20, this is how many times we do the 6 jumps.
Then we simply do 6x20 to get 120 jumps per minute!

What is the ratio of the areas of AABC to AA'B'C' ?
Help please I only have 36 minutes left
According to my official calculations of the picture above, A'B'C' is 4x larger than the triangle ABC. Which would mean that ABC' is from a dialation of 4 from the original triangle, ABC.
I can't remember how you put it into the ratio form, but I think its 1:4??????

Does anyone know the answer to this?!
Answer:
65°
Step-by-step explanation:
Properties of a triangle:
Triangles always have 3 sidesThe sum of the interior angles of a triangle must be equal to 180°.To solve:
Since the angles inside of a triangle must always be equal to 180, use the following formula to solve:a + b + c = 180(The variables can be assigned to any value in this situation)Since two angles are already given, replace 2 variables:a + 85 + 30 = 180Solve the equation by subtracting on both sides:a = 65The value of a is the measure of the missing angle. The problem is solved.Answer:
the missing angle is 65
Step-by-step explanation:
a whole triangle is 180
subtract the given angles from 180
180
- 85
----------
95
subtract the remaining angle
95
- 30
---------
65

Question: Based on the data set above for the hours per day sixth graders spend using an electronic device, what is the mean number of hours sixth graders use an electronic device?
No links, useless words, or anything like that. I will report you.
Answer:
Step-by-step explanation:
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
1+1+1+1+2+3=9
2+4+4+5+6+6+7+8+8=50
50/9=5.55555555556
or
9/50=0.18

Answer:
169.56
Step-by-step explanation:
The formula for finding the volume of a cylinder is: πr²h
First step: Plug in the radius and height: π•3²•6
Second step: Plug 3.14 for π: 3.14•3²•6
Third step: Simplify the equation: 3.14•9•6
Fourth step: Multiple to get your final answer: 3.14•9=28.26•6= 169.56
Martina had 15 pounds of flour at her bakery. She used 1/5 pound of flour to make cookies every day until all the flour was gone. How many days did Martina use flour to make cookies?
Answer:
5 days
Step-by-step explanation:
Martina has 15 pounds of flour at her bakery
She uses 1/5 of the flour to make cookies everyday
1/5 × 15
= 3
Hence the number of days used to make the cookies can be calculated as follows
= 15/3
= 5

Find and interpret the mean absolute deviation of the data. Round your answer to the nearest tenth, if necessary. The mean absolute deviation is . Question 2 response - correct
Required data:
_______________
| 60 | 105 | 80 | 125 |
| 140 | 95 | 65 | 170 |
----------------------------
Answer:
Mean absolute deviation = 30
Variability of the data about the mean value is 30
Step-by-step explanation:
Mean = Σx / n
n = sample size = 8
Mean = (60 + 105 + 80 + 125 + 140 + 95 + 65 + 170) = 840 / 8 = 105
Mean absolute deviation = Σ|x - mean| ÷ n
( |60-105| + |105-105| + |80-105| + |125 - 105| + |140-105| + |95-105| + |65-105| + |170-105|) / 8
(45 + 0 + 25 + 20 + 35 + 10 + 40 + 65) / 8
240 / 8
= 30
The variability of data about the central point or mean value is 30.

whats the slope using Rise/Run?
thanks, if you help
Answer:
the slope of the given line is m = rise / run = -1/2
Step-by-step explanation:
Going from (1, -1) to (3, -2), the 'rise' is actually a drop of 1 unit; the 'run' is +2.
Thus, the slope of the given line is m = rise / run = -1/2
Triangle abc and xyz are congruent ,/_A is one half the size of /_B,/_y is 90° ./_c and /_z each have a measure of 45°.What is the measure of /_ a?
Answer:
∠a = 45°
Step-by-step explanation:
We are told that △abc and △xyz are congruent.
Thus;
∠a = ∠x
∠b = ∠y
∠c = ∠z
We are given;
∠y = 90°
Thus, ∠b = 90°
Now,we are told that ∠a is one half the size of ∠b.
Thus; ∠a = ½ × ∠b
∠a = ½ × 90
∠a = 45°

Answer:
x = 19.8
Step-by-step explanation:
Mathematically, when two triangles are similar, the ratio of their corresponding sides are equal
thus, we have it that;
16/28.8 = 11/x
16 * x = 11 * 28.8
x = (11 * 28.8)/16
x = 19.8
