Answer:
C . 2,550 bolts. lol
Step-by-step explanation:
A simple technique to answer a question like this is to
Step 1: multiply 30 by 17000 = 510000
Step 2: divide 510000 by 200 = 2550
Answer:
4
Step-by-step explanation:
If my above assumption is correct, we can easily find the area of the left side of the rectangle by finding the area of 3 things. The first is the area of the entire region.
At = (0.8)(1.0+1.4) = 1.92
Next we need the area of the circle. Which is pi*r^2, with r being height divided by two. (0.4)
C = 0.502
Finally we need to find the area of the rectangle left region. Which is basically the rectangle from the center of the circle region to the end of the left of the entire region. This is just (1.0)(0.8) = 0.8
Finally we can find the area of the light blue area by just subtracting half the area of the circle (dark blue) from the area we just calculated.
0.8 - (0.502 / 2) = 0.549
Now for the probability we do this area divided by total area.
0.549/1.92 = 0.285 or about 0.29 which is just 29%
Answer:
36.25%
Step-by-step explanation:
400 - 255 = 145
145/400 = 0.3625
0.3625 = 36.25%
Answer: (92, 128)
Step-by-step explanation:
According to the Empirical rule,
If the population is normallly distributed, then 95% of the population lies within 2 standard deviations from the mean.
Given: Mean = 110
Standard deviation = 9
The interval of systolic blood pressures represent the middle 95% of males:
(110-2(9), 110+2(9))
= (110-18, 110+18)
= (92, 128)
Hence, the interval of systolic blood pressures that represent the middle 95 % of males = (92, 128)
