As part of quality control, a pharmaceutical company tests a sample of manufacturer pills to see the amount of active drug they
ryzh [129]

Answer:

The z statistic is 0.23.

Step-by-step explanation:

Test statistic (z) = (sample mean - population mean) ÷ sd/√n

sample mean = 104 mg

population mean (mu) = 100 mg

sd = 55 mg

n = 10

z = (104 - 100) ÷ 55/√10 = 4 ÷ 17.393 = 0.23

Kenyon ran for 8 miles each week while training. Here is his record of the number of miles he ran.
diamong [38]

Step-by-step explanation:

Let x be the miles Kenyon ran on tuesday

Let y be the miles Kenyon ran on thursday

Given,

Mon + Tues + Wed + Thu = 8mi

1.2 + x + 1.6 + y = 8 \\ 2.8 + x + y = 8 \\ x + y = 8 - 2.8 \\ x + y = 5.2

also given,

y = x + 0.4 \\  - x + y = 0.4

Now we have x + y = 5.2 as equation 1 and -x + y = 0.4 as equation 2

Using equation 1,

x + y = 5.2 \\ x = 5.2 - y

Substitute this equation into equation 2.

- (5.2 - y) + y = 0.4 \\  - 5.2 + y + y = 0.4 \\  - 5.2 + 2y = 0.4 \\ 2y = 0.4 + 5.2 \\ 2y = 5.6 \\ y = 5.6 \div 2 \\  = 2.8mi

Substitute y = 2.8 into equation 1.

x + 2.8 = 5.2 \\ x = 5.2 - 2.8 \\  = 2.4mi

Therefore Kenyon ran 2.4 miles on tuesday, and ran 2.8 miles on thursday.
