X is 15because 15-10=5
x= 3*5
x=15
The correct option is (B).24 miles.
Z-score is basically another term for the specific number of standard deviations. I suppose we can assume normality here, even though it isn't given, so I'd make a rough sketch.
Otherwise, just use the basic formula:
Given that,
(statistic for a mean) and
(statistic for a standard deviation).
Since z-score must be Less than 1.5, So
![1.5> \dfrac{x-29}{3.6}\\](https://tex.z-dn.net/?f=1.5%3E%20%5Cdfrac%7Bx-29%7D%7B3.6%7D%5C%5C)
![1.5 \times3.6 > x-29\\5.4+29> x\\34.4> x](https://tex.z-dn.net/?f=1.5%20%5Ctimes3.6%20%3E%20x-29%5C%5C5.4%2B29%3E%20x%5C%5C34.4%3E%20x)
I just used normal cdf and got
.
Hence the correct option is (B).24 miles.

Answer:
C) 8
Step-by-step explanation:
Consecutive angles are equal to 180. So 22x+4+180. Solve that to get x=8. Hope I helped and post more questions :)
To make a box and whisker plot, first you write down all of the numbers from least to greatest.
0, 1, 3, 4, 7, 8, 10
The median is 4, so that’s the middle line of the plot.
So now we have:
0, 1, 3, [4,] 7, 8, 10
So next we have to find the 1st and 3rd interquartiles..
0, [1,] 3, [4,] 7, [8,] 10
Those are the next 2 points you put on the plot.
Lastly, the upper and lower extremes. These are the highest and lowest numbers in the data.
[0,] 1, 3, 4, 7, 8, [10]
These are the final points on the plot.
To make the box of a box-and-whisker plot, you plot the 3 Medians of the data: 1, 4, and 8, and connect those to make a box that has a line in the middle at 4.
Next, you plot the upper and lower extremes: 0 and 10, by making “whiskers” that connect to the box. So you draw a line from the extremes to the box.
Answer: 2
Step-by-step explanation:
try each value in the equation
2(0) + 1 = 3
0 + 1 = 3
1 ≠ 3
so 0 doesn’t work
2(1) + 1 = 3
2 + 1 = 3
3 = 3
this works, so the answer is 1
