(8p - 2)(6p + 2)

= {8p(6p + 2)} - {2(6p + 2)}

= 48p² + 16p - 12p -4

= 48p² + 4p - 4

(8p-2)(6p+2)=8p\cdot 6p+8p\cdot 2-2\cdot 6p -2\cdot 2=\\ \\ =48p^2+16p-12p-4=48p^2+4p-4

In a study of the impact of smoking on birth weight, researchers analyze birth weights (in grams) for babies born to 189 women w
kompoz [17]

Answer:

c. Smoking is associated with lower birth weights. When smokers are compared to nonsmokers, we are 95% confident that the mean weight of babies born to nonsmokers will be between 76.5 grams to 486.9 grams more than the mean birth weight of babies born to smokers.

Step-by-step explanation:

The difference in mean birth weights (nonsmokers minus smokers) is 281.7 grams with a margin of error of 205.2 grams with 95% confidence.

Then, we know that the 95% confidence interval is (76.5, 486.9)

LL=M-MOE=281.7-205.2=76.5\\\\UL=M-MOE=281.7+205.2=486.9

<em>a. We are 95% confident that smoking causes lower birth weights by an average of between 76.5 grams to 486.9 grams.</em>

False, it interprets the confidence interval as a probability for individual cases. The confidence interval is a range for the population mean.

<em>b. There is a 95% chance that if a woman smokes during pregnancy her baby will weigh between 76.5 grams to 486.9 grams less than if she did not smoke.</em>

False, it interprets the confidence interval as a probability for individual cases. The confidence interval is a range for the population mean.

<em>c. Smoking is associated with lower birth weights. When smokers are compared to nonsmokers, we are 95% confident that the mean weight of babies born to nonsmokers will be between 76.5 grams to 486.9 grams more than the mean birth weight of babies born to smokers.</em>

True.

<em>d. With such a large margin of error, this study does not suggest that there is a difference in mean birth weights when we compare smokers to nonsmokers.</em>

There is enough evidence, as the lower bound of the confidence is positive. This means that there is only a probability of 0.05/2=0.025 that the true mean weight difference is smaller than 76.5 grams.

Alexei wants to hang a mirror in his boat, and put a frame around it. The mirror and frame must have an area of 19.25 square fee
Drupady [299]
<span>The first part is already in squared terms. "19.25 sq ft" Taking the measurements for the mirror 3ft and 5ft, you'd get: "15 sq ft." Subtract that answer from the previous number to get "4.25 sq ft.

Hope this helps out a little lol :)</span>

81 + 2d &gt; 90, d = 2<br> TRUE OR FALSE
telo118 [61]

Answer:

False

Step-by-step explanation:

False because you plug in 2 for d and makes the equation 81 + 2x2 > 90 then it`s just simple math 2x2 is 4 making it 81 + 4 > 90 and the answer is 85 > 90 which is false
