jolli1 [7]

Answer:

81.9%

Step-by-step explanation:

In a data set with a normal distribution the mean is 59 and standard deviation is three about what percent of the data live between 53 and 62

Using z score formula

z = (x-μ)/σ, where

x is the raw score,

μ is the population mean = 59

and σ is the population standard deviation = 3

For x = 53

z = 53 - 59/3

= -2

P-value from Z-Table:

P(x = 53) = 0.02275

For x = 62

z = 62 - 59/3

= 1

P-value from Z-Table:

P(x = 62) = 0.84134

Hence, the probability of the data live between 53 and 62 is

0.84134 - 0.02275

0.81859

Converting to Percentage.= 0.81859

× 100 = 81.859%

Approximately = 81.9%

Answer:

2 shelves

3 shelves

4 shelves

6 shelves

12 shelves

Step-by-step explanation:

playstation games = 48

xbox games = 36

Each shelf will have the same number of playstation and xbox games.

Find the common multiples of 48 and 36

48 = 2, 3, 4, 6, 8, 12, 16, 24, 48

36 = 2, 3, 4, 6, 9, 12, 18, 36

The common multiples are 2, 3, 4, 6, and 12

Therefore, the possible number of shelves Joe will use is

2 shelves

3 shelves

4 shelves

6 shelves

12 shelves

The table shows the total number y (in billions) of U.S. movie admissions each year for x years. Use a graphing calculator to fi

wariber [46]

Answer:

By rounding up of the constant and coefficient terms, we have;

The line of best, fit is y = 1.23 + 3.46 × 10⁻²·x

Step-by-step explanation:

The table for the data on the number of movie admissions each year is presented as follows;

Year, x ${}$ Admission, y

0 ${}$ 1.24

2 ${}$ 1.26

4 ${}$ 1.39

6 ${}$ 1.47

8 ${}$ 1.49

10 ${}$ 1.57

Using a graphing calculator, we have that the line of best fit is given by the following equation;

y = 1.23047619048 + 3.45714285714 × 10⁻²·x

Which is approximately, y = 1.23 + 3.46 × 10⁻²·x
