Step-by-step explanation:
<u>Part A</u>
According to the Empirical Rule, 99.7% of the data in a normal distribution are ±3σ standard deviations away from the mean. Hence, approximately 99.7% of women over seventy have blood pressures between 134-3σ = 134-3(7) = 134-21 = 113 mmHg and 134+3σ = 134+3(7) = 134+21 = 155 mmHg.
<u>Part B</u>
As 141-134=134-127=7, this represents ±1σ standard deviations away from the mean of 134 mmHg, which corresponds to 68% of the data by the Empirical Rule. Hence, approximately 68% of women over seventy have blood pressures between 127 mmHg and 141 mmHg
Answer:
54 oz. OR 3 3/8 lbs.
Step-by-step explanation:
1) Convert pounds to ounces. There are 16 ounces in a pound. 20 * 16 = 320.
2) Add the remaining 4 ounces. 320 + 4 = 324.
3) Divide 324 by 6. 324/6 = 54.
Final answer: 54 ounces.
NOTE: If you want the answer in pounds, divide 54 by 16. 54/16 = 3 3/8
Final answer b: 3 3/8 pounds
Answer: 6.25
Step-by-step explanation:
Answer:
65/3 = 21 2/3 = 21.666666667
21.66 = 21.661.
21.661 = (21.66 × 100)(1 × 100) = 2166100.
(2166÷2)(100÷2) = 108350 when reduced to the simplest form.
The is 21 2/3
(hope this helps can i plz have brainlist :D hehe)
tep-by-step explanation:
Answer:
One example is the equation:
2x + 6 = 4x/2 + 12/2
To solve this, we need to transpose like terms to the same side.
2x - 4x/2 = 12/2 - 6
2x - 2x = 6 - 6
0 = 0
Since both sides are zero, it means that the equation has infinite number of solutions.
