Answer:
Step-by-step explanation:
<u>1. Cell phone usage</u>
Mon to Sun = 38, 62, 40, 10, 30, 55, 65
- Mean = (38+62+40+10+30+ 55 + 65)/7 = 43 minutes rounded
<u>2. Water bills</u>
Jan to Dec = $40 $42 $40 $38 $48 $50 $58 $62 $56 $46 $44 $44
- Mean = (40+42+40+38+48+50+58+62+56+46+44+44)/12 = $47 rounded
Answer:
n ≥ 29
She needs to do more than 29 pushups on the sixth day.
Step-by-step explanation:
First, we need to use the formula for finding the average. We currently have numbers for the first 5 days.
(22+26+21+25+27+n)/6 = 25
Multiply both sides by 6.
25*6 = 150
150-27-25-21-26-22=x
x=29
Since it is an inequality, Sarah needs to do more than 29 pushups on the sixth day.
Answer:
Not sure but 2 would be the same as 1 so 39.5 and 3 and 4 would be 50.5
Step-by-step explanation:
1 and 3 make a right angle and so does 4 and 2 so all I did was subtract 39.5 from 90 since a right angle=90 degrees
s=1/23
given equation in term of s is 12+3/2s-1/2-3/4s=5/4s
to solve this first we need to take LCM on left hand side and right hand side we can rewrite given equation as 12/1+3/2s-1/2-3/4s=5/4s now taking LCM of {1,2s,2,4s,4s} is 4s then the equation becomes 48s/4s+6/4s-2s/4s-3/4s=5/4s
(48s+6-2s-3) /4s=5/4s now cancel out denominator of both side we get 48s+6-2s-3=5 this implies 46s+3=5
46s=2
s=1/23
Hence the value of s is 1/23
