You have to multiply 15 by 180,if I'm wrong then you'll have to divide
Answer:
Given,
2 cups of yellow paint is needed for every 3 cups of red paint to make a batch of orange paint,
So, the ratio of yellow paint and red paint in a batch of orange paint = 2 : 3
Make two number lines,
First one represents the multiple of 2 and second one represents the multiples of 3,
By the double number line ( shown below ),
It is clear that,
For 3 batches of orange paint, 6 cups of yellow paint and 9 cups of red paint are needed.
Answer:
75% of the households have between 2 and 6 televisions
Step-by-step explanation:
From the question, we can deduce the following;
sample size n= 8
sample mean μ = 4
standard deviation σ = 1
Using Chebychev’s theorem;
P(2 ≤ X ≤ 6) = P(2-4 ≤ (X - μ) ≤ 6-4)
= P(-2 ≤ (X-μ) ≤ 2) = P(|X-μ| ≤ kσ) ≥ (1 - 1/k^2) ≥ (1- 1/2^) = 1- 0.25 = 0.75 ( same as 75%)
Answer: If you want the graph of f(x)=3x-2 and f(x)=x-2 then
Step-by-step explanation:
the blue line is f(x)=3x-2 and the green line is f(x)=x-2
f(x) is the same thing as y so all you have to do is y=3x-2 in a graphing calculator and you will get your answer
80/1hour for 3/4 hours= 80*3=240/4=60
55/1hour=55+(55/5)=55+11=66
60+66=126km
126km
