Answer:
Step-by-step explanation:
The mean of the gas mileages is 317÷16=19.8125
317 is the sum total of all the figures and 16 is the number of figures in the distribution
Standard deviation is the square root of the variance and the variance is the mean of all squared deviations
The 16 squared deviations are
7.9102(×2) + 3.2852(×2) + 0.6602(×3) + 0.0352(×4) + 1.4102(×3) + 10.1602 + 17.5352 = 56.4382
56.4382÷16 = 3.5274
This is the Variance. The standard deviation is herefore √3.5274 =1.878 ~ 1.88 (to 2 decimal places)
(B) Chebyshev's inequality predicts that 75% of the selection will fall within 2 standard deviations of the mean
2×1.88=3.76
19.8125-3.76 = 16.05
19.8125+3.76= 23.57
The gas mileages are between 16.05 and 23.57
(C) the actual % of SUV models of the sample that fall in the above range is (15/16 × 100) = 93.75%
(D) the empirical rule gives the more accurate prediction
Answer:
6
Step-by-step explanation:
y=mx+b
93.40=8.40x+43
the 93 is the amount we want to get to, 8.40 represents the value of each sign and the 43 is the original cost
(4,1) is a possible solution. Hope this helps. :)
Cara's rate of commission is 12%.
Step-by-step explanation:
Given,
Paycheck = $6500
Salary = $1000
Commission = Paycheck - Salary
Commission = 6500-1000 = $5500
Total sales for the week = $45000
Commission rate = 
Rounding off to nearest whole number.
Commission rate = 12%
Cara's rate of commission is 12%.

Answer:
g= 4
Step-by-step explanation:
first, you want to subtract 36 from both sides of the equation to get rid of that and the plus sign, and get 6g by itself so that would be -6g=-24. then, you want to divide -6 from both sides, so you get g=4 as your answer. and I promise you that it's not so hard once you get the hang of it.
