She must mix 1.5 cups of pineapple juice into the pitcher.

Since Cindy is making a fruit juice drink, and the recipe calls for 5 parts apple juice and 3 parts pineapple juice, and Cindy puts 2 1/2 cups of apple juice into a pitcher, and Cindy wants the juice drink in her pitcher to taste the same as the drink in the recipe, to determine how much pineapple juice does she need to mix into the pitcher, the following calculation must be performed, proposing a cross multiplication:

  • 5 = 2 1/2
  • 3 = X
  • 5 = 2.5
  • 3 = X
  • 3 x 2.5 / 5 = X
  • 7.5 / 5 = X
  • 1.5 = X

Therefore, she must mix 1.5 cups of pineapple juice into the pitcher.

Suppose that a brand of lightbulb lasts on average 1730 hours with a standard deviation of 257 hours. Assume the life of the lig
Debora [2.8K]

Answer:

P [  1689  ≤   X  ≤  2267 ]  = 54,88 %

Step-by-step explanation:

Normal Distribution

Mean        μ₀  =  1730

Standard Deviation      σ  = 257

We need to calculate  z scores for the values   1689     and      2267

We apply formula for z scores

z =  ( X -  μ₀ ) /σ

X = 1689     then

z = (1689 - 1730)/ 257      ⇒ z = - 41 / 257

z  = -  0.1595

And from z table we get  for  z =  - 0,1595

We have to interpolate

        - 0,15          0,4364

        - 0,16          0,4325

Δ  =   0.01           0.0039

0,1595  -  0,15  =  0.0095

By rule of three

0,01                  0,0039

0,0095                 x ??      x  =  0.0037

And    0,4364  -  0.0037  = 0,4327

Then    P [ X ≤ 1689 ]  =  0.4327     or    P [ X ≤ 1689 ]  = 43,27 %

And for the upper limit  2267  z  score will be

z  =  ( X - 1730 ) / 257       ⇒  z =  537 / 257

z  =  2.0894

Now from z table   we find  for score   2.0894

We interpolate and assume  0.9815

P [ X ≤ 2267 ]  =  0,9815

Ths vale already contains th value of   P [ X ≤ 1689 ]  =  0.4327

Then we subtract  to get    0,9815  -  0,4327   = 0,5488

Finally

P [ 1689  ≤   X  ≤  2267 ]  =  0,5488  or  P [  1689  ≤   X  ≤  2267 ]  = 54,88 %
