Answer: You are missing a 4.

Step-by-step explanation: If you said the answer is 20, 4 is missing. We can add up the follow equation before putting 4.

(4 + 3) + (4 + 5)

   7     +    9 = 16 + 4 = 20.

Hence, 20 is your answer.

Shkiper50 [21]

Answer:

Step-by-step explanation:

given that the following data represent the discrete probability distribution for the number of stars that reviewers have a first edition statistics reference book.

Stars            5    4      3         2    1

Probability 25% 35% 20% 10% 10%

H0: Second edition is as per the above probabilities

Ha: atleast one is different from the above probability

(two tailed chi square test)

Alpha = 0.025

Assuming H0 to be true we calculate expected frequencies for total 80

chi square calculatons are shown below

df = 4

                  5     4         3 2 1      Total

Observed 28    28 13 6 5      80

Expected 20    28 16 8 8      80

chi square        

(O_E)^2/E 3.2 0 0.5625 0.5 1.125 5.3875

p value =0.1455

Since p value >0.025, we accept H0

The expected requency of three-star reviews is ________.16

Answer:

600 Cheese and 900 Pepperoni

Step-by-step explanation:

Setup the equation with 2c(Cheese) + 2.5p(Pepperoni) = $3450(Total Made).

In addition to the equation c + p = 1500(Number of pizzas sold)

Using the second equation (c + p = 1500) solve for one of the variables.

Lets use :

  1. p = 1500 - c
  2. Plus this equation into the original equation, 2c + 2.5(1500 - c) = 3450
  3. Distribute 2.5, 2c + 3750 - 2.5c = 3450
  4. Combine like terms -0.5c + 3750 = 3450
  5. Solve for c: c = 600
  6. Plus 600 in for c into any equation ( lets use c + p = 1500)
  7. 600 + p = 1500
  8. P = 900
