12) This answer is incorrect because it does not take into account the entire sample. Instead, this excludes the two zero values and divides by eight rather than ten. As a result, the correct answer would be 55/10 = 5.5

13) Mean: (93+91+98+100+95+92+96)/7 = 95
Median: 91, 92, 93, 95, 96, 98, 100
She would need a 95 on the next test if the median and mean were to stay the same, because adding any other number than 95 to these test scores will change the mean, and the median will stay the same if she receives a 95.

14a) (16000+20000+25000+35000)/4 = 24000 for Company A
(21000+23000+36000+48000)/4 = 32000 for Company B

14b) (20000+25000)/2 = 22500 for Company A
(23000+36000)/2 = 29500 for Company B

14c) Company B, both their mean and median are higher than Company A, showing that it's extremely likely that she'll receive a higher commission working for Company A, rather than B.

Answer from: Quest

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

$4/2 = 2\\7/3.5=2\\8/4=2\\10/5=2$

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

$y=\frac{x}{2}$

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

Answer from: Quest

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

These figures are similar. the perimeter and area of one are given. the perimeter of the other is al
