A pan of lasagna cut into 100 servings is equally shared among a group of people. For Exercises

Volgvan

53). 100 servings / 20 people = (100/20) (svngs/ppl)

   = 5 servings per person.

   Each person gets 1/20 = 5% = 0.05 of the pan.

54). 100 servings / 40 people = (100/40) (svngs/ppl)

   = 2.5 servings per person.

   Each person gets 1/40 = 2.5% = 0.025 of the pan.

55). 100 servings / 30 people = (100/30) (svngs/ppl)

      = (3 and 1/3) servings per person.

   Each person gets 1/30 = (3 and 1/3) % = 0.0333... of the pan.

Answer:

sqrt(x+7) - log(x+2)

Step-by-step explanation:

f(x) = sqrt(x+7)

g(x) log(x+2)

f(x) - g(x) = sqrt(x+7) - log(x+2)

You are interested in estimating the the mean age of the citizens living in your community. In order to do this, you plan on con

Assoli18 [71]

Question:

You are interested in estimating the the mean age of the citizens living in your community. In order to do this, you plan on constructing a confidence interval; however, you are not sure how many citizens should be included in the sample. If you want your sample estimate to be within 5 years of the actual mean with a confidence level of 97% , how many citizens should be included in your sample? Assume that the standard deviation of the ages of all the citizens in this community is 18 years.

Answer:

61.03

Step-by-step explanation:

Given:

Standard deviation = 18

Sample estimate = 5

Confidence level = 97%

Required:

Find sample size, n.

First find the Z value. Using zscore table

Z-value at a confidence level of 97% = 2.17

To find the sample size, use the formula below:

$n = (Z * \frac{\sigma}{E})^2$

$n = ( 2.17 * \frac{18}{5})^2$

$n = (2.17 * 3.6)^2$

$n = (7.812)^2$

$n = 61.03$

Sample size = 61.03

The circle P has a center at (0, 0) and a point on the circle at (0, 4). If it is dilated by a factor of 4, what is the distance

galina1969 [7]

Answer:

A. 32

Step-by-step explanation:

If the center is (0, 0) and a point is (0, 4) then the distance from the center to that point is 4 units. That distance is the radius. If you are dilating by a factor of 4, multiply the radius by 4 and you get 16. The new radius is 16 and the diameter= radius*2.

16*2=32

If p is the hypothesis of a conditional statement and q is the conclusion, which is represented by ~p → ~q?

AfilCa [17]

Conditional statement is a statement with a hypotesis and a conclusion:

If $\text{ \underline{ hypothesis } } p$ , then $\text{ \underline { conclusion } } q$ or mathematically $p\rightarrow q$ .

Converse statement of $p\rightarrow q$ is statement $q\rightarrow p$ .

If you negate (that means stick a "not" in front of) both the hypothesis and conclusion, you get the inverse: $\neg p\rightarrow \neg q$ .

Finally, if you negate everything and flip p and q (taking the inverse of the converse) then you get the contrapositive: $\neg q\rightarrow \neg p$ .

Then,

Answer: the correct choice is D (the inverse of the original conditional statement).
