Answer:
D: 160
Step-by-step explanation:
Fifth graders read 68, which is easy to see. Fourth graders read between 48 and 52, the bar appears to be directly in the middle of the two lines, so we say they read 50. Third graders read between 40 and 44, again the bar appears to be directly in the middle so we say they read 42.
42+50+68=160
Answer:
He would of saved 455$
Step-by-step explanation:
Because for 4 weeks he saved 35% of 200$ which would be 70 and 70+70+70+70 is 280$ and then he saved 175 dollars on the 5th week because 7/8 of 200 is 175 so 280+175= 455
I hope this helps!
The probability that a data value is between 54 and 66 is 81.9%
z score is used to determine by how many standard deviations the raw score is above or below the mean.
The z score is given by:

Given that μ = 62, σ = 4
For x = 54:

For x = 66:

P(54 < x < 66) = P(-2 < z < 1) = P(z < 1) - P(z < -2) = 0.8413 - 0.0228 = 81.9%
The probability that a data value is between 54 and 66 is 81.9%

it should be 42percent I didn't really know my bad
9 .............. 100%
x................ 15%
100x = 15 . 9
100x = 135
x = <u>135</u>
100
x = 1,35
