Answer:
36 White cars
Step-by-step explanation:
total of 40 white cars and yellow cars" means 40 = W + Y
"9 times as many white cars as yellow cars" means 9Y = W
9W + 9Y = 360 (first equation; multiply (W+Y=40) by 9 to eliminate Y)
W - 9Y = 0 (carefully revise the second equation)
------------------- (Elimination method: add the equations)
10W = 360
W = 36 Ans: 36 White cars
Checking (very important):
40 = W + Y
40 = 36 + Y
4 = Y
is 9(4) = 36
36 = 36
Answer:
cup of pineapple juice.
Step-by-step explanation:
We are told that Francine uses 2/3 cup of pineapple juice for every 1/3 cup of orange juice to make a smoothie. In order to get the number of cups of pineapple juice Francine will use for 1 cup of orange juice, we will apply the following expression;
2/3 cup of pineapple juice = 1/3 cups of orange juice
1 cup of pineapple juice = x cups of orange juice
Cross multiply
divide both sides of the equation by 3
divide both sides by 2
Hence Francine uses number of cups of pineapple juice for 1 cup of orange juice.
Answer:
256 ways
Step-by-step explanation:
Okay so n cannot be in the nth place, but there are 5 places available.
So thinking about it technically you can have 4 of each number in a different spot not their own, and 4x4x4x4 = 256
However, if that doesn't work, you could try 4! which is 4x3x2x1 = 24
Hope that helps :)
Answer:
At 0.10 significance level, reject H0
At 0.05 significance level, reject H0
At 0.01 significance level, fail to reject H0
At 0.001 significance level, fail to reject H0
Step-by-step explanation:
The null hypothesis is rejected if the p-value is less than or equal to the significance level.
Fail to reject the null hypothesis if the p-value is greater than the significance level.
At 0.1 and 0.05 significance level, the null hypothesis is rejected because the p-value (0.0174) is less than the significance levels.
At 0.01 and 0.001 significance level, fail to reject the null hypothesis because the p-value (0.0174) is greater than the significance levels.
