x+19= 26
x+19-19= 26-19
x= 7
Check answer by using substitution method
x+19= 26
7+19= 26
26= 26
Answer is x= 7 (D.)
That is 12*11*10*9*8*7*6*5*4=79833600 ways
The empirical rule states that at 95% the measurements would be within 2 standard deviations of the mean.
You are given a mean of 68 inches and a standard deviation of 4.
2 times the standard deviation = 2 x 4 = 8
So 95% of the heights would be between 68-8 = 60 inches and 68+8 = 76 inches.
Plug in 4
8*2 + 9(4)-7
16 + 36 -7
45
Answer: So you're looking for 43/19 but not to the nearest hundredth, so maybe your teacher is looking for the decimal to be rounded to the nearest tenth or one thousandth... Here's how you would solve this...
Step-by-step explanation:
49/13 or 49 ÷ 13
49/13 = 3.76923076923
To the Nearest 10th: Answer ≈ 3.8
To the Nearest 1,000th: Answer ≈ 3.769
To the Nearest 100th: Answer ≈ 3.77
Note: I listed the nearest 100th in case you need it, I hope this helps you!
