Answer:
y=-5/3x+3
Step-by-step explanation:
To find slope intercept form, distribute the slope into the parenthesis:
y+2=-5/3x+5
Subtract 2 from both sides
y+2=-5/3+5
-2 -2
y=-5/3x+3
Answer:
thus next three terms are -3,-5,-7
Step-by-step explanation:
a=1
first find d
-1-1
-2
then a.p= a,a+d,a+2d,a+3d,a+4d
=1,1-2,1+2×-2,1+3×-2,1+4×-2
=1,-1,1-4,1-6,1-8
=1,-1,-3,-5,-7

Answer:
823.7 m^2
Step-by-step explanation:
The ratio of the side lengths is 6/5.
The ratio of the areas is the square of the ratio of the side lengths, 36/25.
572 m^2 * 36/25 = 823.7 m^2
Answer:
The mean age of the frequency distribution for the ages of the residents of a town is 43 years.
Step-by-step explanation:
We are given with the following frequency distribution below;
Age Frequency (f) X 
0 - 9 30 4.5 135
10 - 19 32 14.5 464
20 - 29 12 24.5 294
30 - 39 20 34.5 690
40 - 49 25 44.5 1112.5
50 - 59 53 54.5 2888.5
60 - 69 49 64.5 3160.5
70 - 79 13 74.5 968.5
80 - 89 <u> 8 </u> 84.5 <u> 676 </u>
Total <u> 242 </u> <u> 10389 </u>
Now, the mean of the frequency distribution is given by the following formula;
Mean =
=
= 42.9 ≈ 43 approx.
Hence, the mean age of the frequency distribution for the ages of the residents of a town is 43 years.
