Step-by-step explanation:
He has 3 shelves...each shelf can hold 40 video games.....40 * 3 = 120...so he has room for 120 video games.
and if he already has 85, then he would need : (120 - 85) = 35 more to fill up the shelves
Answer:
a) 3.16
Step-by-step explanation:
<u><em>Explanation:-</em></u>
<em>Given sample size 'n' =4</em>
mean of x⁻ = ∑x / n
= 
x⁻ = 16
Given data
x 13 14 17 20
x - x⁻ -3 -2 1 4
(x-x⁻)² 9 4 1 16
∑(x-x⁻)² = 9 + 4 + 1 +16 =30
The sample Variance
S² = ∑(x-x⁻)²/n-1

<em>The standard deviation of the sample </em>
<em> S = √10 = 3.1622 ≅3.16</em>
Step-by-step explanation:
11/4 x + 3/2y = 34
since for 3/2teaspoon of balsamic vinegar 11/4 teaspoon of olive oil is added.
hence the number of times you add 3/2teaspoon of balsamic vinegar should be the same as the number of times you add 11/4teaspoon of olive oil.
Hence y = x
11/4y + 3/2y = 34
multiplying through by 4 gives:
11y + 6y = 4 × 34
17y = 4 × 34
dividing both sides by 7 gives:
y = 4 × 2 = 8
x = 8
hence you add 11/4(8) = 22 table spoon of olive oil to 3/2(8) = 12 table spoon of balsamic vinegar to get 34 teaspoon of bread dip.
Answer: we are simply to subtract the length of the gold ribbon which is 2 4/6 ft from the length of the silver ribbon, 5 2/6 feet. Mathematically,
5 2/6 feet - 2 4/6 feet = 8/3 feet
Therefore, Gina has 8/3 feet more of the silver ribbon than the golden ribbon.
