Answer:
The product of two fractions can be calculated as follows:
![\frac{a}{b}\cdot \frac{c}{d}=\frac{a \cdot c}{b \cdot d}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bb%7D%5Ccdot%20%5Cfrac%7Bc%7D%7Bd%7D%3D%5Cfrac%7Ba%20%5Ccdot%20c%7D%7Bb%20%5Ccdot%20d%7D)
So, the numerator is the product of the numerators of the two fractions, and the denominator is the product of the denominators of the two fractions.
In this problem, we know that the product is 6/40, so:
![ac = 6\\bd = 40](https://tex.z-dn.net/?f=ac%20%3D%206%5C%5Cbd%20%3D%2040)
This means:
![c=\frac{6}{a}\\d=\frac{40}{b}](https://tex.z-dn.net/?f=c%3D%5Cfrac%7B6%7D%7Ba%7D%5C%5Cd%3D%5Cfrac%7B40%7D%7Bb%7D)
So we just need to find 2 pairs of numbers a, b to make c and d integers.
The first choice we use is:
a = 3
b = 2
So we get:
![c=\frac{6}{3}=2\\d=\frac{40}{2}=20](https://tex.z-dn.net/?f=c%3D%5Cfrac%7B6%7D%7B3%7D%3D2%5C%5Cd%3D%5Cfrac%7B40%7D%7B2%7D%3D20)
So the first pair of fractions is
The second choice we use is:
a = 2
b = 10
So we get:
![c=\frac{6}{2}=3\\d=\frac{40}{10}=4](https://tex.z-dn.net/?f=c%3D%5Cfrac%7B6%7D%7B2%7D%3D3%5C%5Cd%3D%5Cfrac%7B40%7D%7B10%7D%3D4)
So the second pair of fractions is
![\frac{2}{10},\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B10%7D%2C%5Cfrac%7B3%7D%7B4%7D)
Answer:
If this is the question: "The interval estimate of the mean value of y for a given value of x is a. prediction interval estimate b. confidence interval estimate c. average regression d. x versus y correlation interval" then your answer is B
Step-by-step explanation:
Answer:
404
Step-by-step explanation:
Use the recursive formula until you get to the term you want.
f(1) = 4
f(2) = f(1)^2 +4 = 4^2 +4 = 20
f(3) = f(2)^2 +4 = 20^2 +4 = 404
