Answer:
8 phone cells
Step-by-step explanation:
We are told that he spent 14 minutes on the phone while routing 7 phone calls.
Now, we want to find the number of phone cells he will route for a total of 16 minutes.
Thus, by proportion using unit rates;. Number of minutes spent pet phone cell = 14 minutes ÷ 7 phone calls = 2 minutes per phone cell
Therefore, for 16 minutes, number of phone cells will be;
16 minutes ÷ 2 minutes per phone cell = 8 phone cells

Answer:
No, because 1:15 is not the same ratio as 2:24.
Step-by-step explanation:
2/24 reduces to 1/12 not 1/15 so these ratios are not the same.

Answer:
15x^2-14x-4
Step-by-step explanation:
(8x^2 * x-7x+2)+(7x^2 -7x-6)
you take out the parentheses
you add the common ones so -7x+-7x= -14x
8x^2 +7x^2 = 15x^2
and 2-6= -4
so in total it's 15x^2-14x-4
Answer: 11x^2 -16x-3
Step-by-step explanation:
Solution:
Your problem → (8x^2-7x+2) + (3x^2-9x-5)
(8x2-7x+2)+(3x2-9x-5)
=8x2-7x+2+3x2-9x-5
=8x2+3x2-7x-9x+2-5
=11x2-16x-3
Solve for h.
h/10 + 5 = 25
so what’s h ??
Answer:
h=200
Step-by-step explanation:
h/10+5=25
h/10=20
h=200
h/10 + 5 = 25
Subtract 5 from each side to get h/10 alone.
h/10 + 5 - 5 = 25 - 5
h/10 = 20
Multiply both sides by 10 to get h alone.
h/10 • 10 = 20 • 10
h = 200
h = 200. I hope this helps!

Which point on the scatter plot is an outlier? A graph shows scale on x axis from 0 to 14 at increments of 2 and a scale on y axis from 0 to 70 at increments of 10. Dots are made at ordered pairs 0, 0 and 1.8, 5 and 2.3, 9 and 2.8, 11 and 3.5, 15 and 4.1, 22 and 4.2, 26 and 5.5, 18 and 5.8, 29 and 6, 30 and 6.1, 15 and 6.5, 32 and 7.2, 35 and 7.3, 38 and 8.5, 42. The point 12, 10 is labeled as P, the point 6, 40 is labeled as Q, the point 3, 20 is labeled as R, and the point 0, 0 is labeled as S. Point P Point Q Point R Point S
Answer:
Point 'B'
Step-by-step explanation:
This is because outliers are points on a scatter plot that are not in the cluster, a cluster is a group of 2 or more scatter points. Therefor, the outlier would be point 'P'.
Answer:
answer is P

Answer:
a) 10.5
b) 25.32
Step-by-step explanation:
Plug in 2.3 for n in both equations.
First equation:
5 (2.3 - 2) + 9
5 (0.3) + 9
1.5 + 9
10.5
Second equation:
8 (2.3^2) - 17
8 (5.29) - 17
42.32 - 17
25.32

Determine the type of correlation.
Answer:
Positive Correlation
Step-by-step explanation:
The graph shown as a positive correlation.
Two variables move in the same direction in a positive correlation.
You can also tell that the graph has a correlation that is positive because of the line moving in a upward direction from left to right.
Hope this helps.

28inch^2
Step-by-step solution:Rectangle:
[Length x Breadth]
5 + 3 = 8inch
8 x 2.5 = 20inch^2
Right Triangle:
[1/2 x Base x Height]
1/2 x 5 x 2 = 1/2 x 10
= 5inch^2
Left Triangle:
[1/2 x Base x Height]
1/2 x 3 x 2 = 1/2 x 6
= 3inch^2
20 + 5 + 3 = 28inch^2
How much of a radioactive kind of antimony will be left after 120 days if you start with 904 grams and the half-life is 60 days?
==========================================
Explanation:
1/2 = 0.5
Every 60 days, the amount cuts in half.
We start with 904 grams and after 60 days, we have 904*0.5 = 452 grams left over.
After another 60 days, we have 452*0.5 = 226 grams left over.
-------------
Alternative Method:
We can apply the half-life formula.
y = a*(0.5)^(x/H)
where,
y = final amount after x daysa = initial amountx = number of days that elapseH = number of days in a half-lifeIn this case,
a = 904 is the starting amountH = 60 is the number of days until another half-life occursWhen x = 120 days go by, we have....
y = a*(0.5)^(x/H)
y = 904*(0.5)^(x/60)
y = 904*(0.5)^(120/60)
y = 904*(0.5)^(2)
y = 904*(0.25)
y = 226 grams of antimony left over.
This method is preferred over the first method if you have x be some non-multiple of 60, or if x is fairly large.
