Because the letters a and b are variables
Answer:
11) 140/8 = 17.5
12) 38/3 = 12.667
13) 114/9 = 12.667
14) 7/2 = 3.5
15) 14/9 = 1.556
Step-by-step explanation:
To solve each problem you need to multiply the numerator by the whole number:
11) 7*20 = 140
12) 2*19 = 38
13) 6*19 = 114
14) 1*7 = 7
15) 7*2 = 14
Next, you put these numbers back into their corresponding numerators and divide:
11) 140/8 = 17.5 (You can simplify this fraction to 70/4 if needed)
12) 38/3 = 12.667 (This answer is rounded to the thousandths place)
13) 114/9 = 12.667 (This answer is rounded thousandsths place)
14) 7/2 = 3.5
15) 14/9 = 1.556 (This answer is rounded thousandths place)
**These are the improper fractions written as mixed ones** :
11) 17 1/2
12) 12 2/3
13) 12 2/3
14) 3 1/2
15) 1 5/9
I hope this helps!
To find the test statistic or z-score given sample number (n), sample mean (x), standard deviation (σ), and population mean (μ), we can use
Given that n = 36, x = 24.6, μ = 20, and σ = 12,
From this, we see that the test statistic is 2.3.
Answer: 2.3
Answer: y = 2x + 12
Explanation: The slope-intercept form is y = mx + b, where m is slope and b is the y-intercept. Substituting 2 for m, 6 for x, and 24 for y, we have 24 = 2(6) + b. Simplifying, we get that b = 12, so the equation is y = 2x + 12.
