Answer:
Skewed to the left
Step-by-step explanation:

The type of distribution
From the given data, we have:
--- Mean and Median are not equal
and
--- Median is greater than mean
<em>When the median is greater than the mean; the histogram is expected to be left skewed</em>
<span>In math notation, we've done this: z = (X - μ) / σ = (940 - 850) / 100 = 0.90
where z is the z-score
X is Vivian's score (940)
µ is the mean (850)
σ is the standard deviation (100)
As you may know, in a normal distribution it's expected that about 68% of all observations will fall within 1 standard deviation of the mean, 95% will fall within 2 standard deviations, and 99% will fall within 3 standard deviations.
940 lie before the first standard deviation, in which 16.5% is above it
since 940 is 0.9 from the mean and 0.1 from the first standard deviation
so above it is 17.5 % = 0.175 or about 0.18 </span>
The number is 24. If 8 is one third of the number, you multiply 8 by 3 to find the number, which is 24.
There are 14 boys, therefore 16 girls.
Ratio of boys:girls is 14:16
14/16 = 7/8 so answer is the 3rd option.
Answer:
the first one is 192 and the second is 396 the third is 216 the fourth is soapy suds
Step-by-step explanation:
the first you just do 4x6x8
the second you just do 9x8x11 and then divide by 2
the third you just multiply 9x6x4 or you could do 3x4x9 and multiply that by 2
the fourth is soapy suds bc it has a larger volume of 1248 while clean and bright only has a volume of 936
