Answer:
1. The mean hemoglobin level in men is not equal to the mean hemoglobin level in women and
2. There is more hemoglobin in the average man than in the woman
Step-by-step explanation:
The confidence interval is from
-1.76 g/dl < μ₁ - μ₂ < -1.62 g/dl
Here we note that the range in the confidence interval for the difference between the two means lie in the negative part of the number line which is indicative of that μ₁ - μ₂ ≠ 0 or μ₁ ≠ μ₂
That is the statistic of the confidence interval implies that the mean hemoglobin level in men is not equal to the mean hemoglobin level in women and
That there is more hemoglobin in the average man than in the woman.
16-20 are correct. <em>Remember to mark the first #20 as A</em>
The last #20 is wrong. The answer is B. 95 minutes.
10:55 - 11:00 = 5 minutes
11:00 - 12:00 = 60 minutes
<u>12:00 - 12:30</u> = <u>30 minutes</u>
Total = 95 minutes
Oh my goodness . . .
What do you get when you multiply a number by itself ?
Do you get the square of the number ?
And what do you get when you square the square root of a number ?
Is it the number inside the square root ?
For just a second, let's take the quantity (4t - 3) and call it ' Q '.
Then the problem is to multiply
√Q times √Q .
Isn't that just ' Q ' ?
And is this enough help ?
Answer:
about 8 cm
Step-by-step explanation:
The formula for the area of a regular polygon is ...
A = 1/2Pa . . . . where P is the perimeter and "a" is the apothem, the distance from the center to a side
Filling in your numbers, we have ...
20 cm^2 = (1/2)P(5 cm)
Dividing by the coefficient of P, we find ...
2×(20 cm^2)/(5 cm) = P = 8 cm
The perimeter of the pentagon is about 8 cm.
_____
<em>Comment on the problem</em>
This calculation makes use of the area formula, as apparently intended. A regular pentagon with an apothem of about 5 cm will have an area of about 90.8 cm^2. The given geometry is impossible, as the pentagon is nearly 10 cm across. It cannot have a perimeter of only 8 cm.
