Answer:
26.25
Step-by-step explanation:
y = 8.75(3)
y = 26.25
21 + 28 = 49 students
Ration of history 21 to students 49 = d)21:49
The pair of numbers that would be in the columns, considering the proportional relationship, is given as follows:
20 would be in the column for 2, and 60 would be in the column for 6.
<h3>What is a proportional relationship?</h3>
A proportional relationship is a special linear function, with intercept having a value of zero, in which the output variable is obtained with the multiplication of the input variable and the constant of proportionality k, as shown as follows:
y = kx
The table is extended to represent more equivalent ratios for 2:6, hence the constant of the relationship is given as follows:
k = 6/2 = 3.
Hence the equation is:
y = 3x.
The values given by each column are given as follows:
When x = 20, the numeric value of the relationship is of:
y = 3 x 20 = 60.
Hence the first option is correct.

#SPJ1
Answer:D) 0.6375
Step-by-step explanation:
See, the probability that Kevin would inherit diabetes is 0.75
The accuracy of this test is 0.85
See as there is 85% chance of that the test will make right prediction so 85% of 0.75 is that probability that Kevin has diabetes and test will predict it correctly.
85% of 0.75 is 0.75*0.85
= 0.6375
Hope it helps!!!
