Answer:

0.75 %

Step-by-step explanation:

Given,

A 45 gm tube of 1% clotrimazole cream is combined with 15gm of base.

Since, the percentage of clotrimazole cream in base = 0 %,

Let x be the percentage of clotrimazole cream in the resultant solution,

So, we can write,

1 % of 45 gm + 0 % of 15 gm = x % of (45 + 15) gm

\implies \frac{1\times 45}{100}+\frac{0\times 15}{100}=\frac{x\times 60}{100}

\implies \frac{45}{100}+0=\frac{60x}{100}

\implies \frac{45}{100}=\frac{60x}{100}

\implies 45 = 60x

\implies x = \frac{45}{60}=0.75\%

i can only help you with the volume of #5.

So the volume of a cylinder is = πr²h.

First , put the numbers in the equation.

π(6)² (14)

Next you solve.

π(6)²(14) = 36 (14) π = 504π


V= 504π

The length of human pregnancies from conception to birth varies according to a distribution that is approximately normal with me
iragen [17]

Answer:

a) 229 and 305 days

b) 229 days or less

c) 305 days or more

Step-by-step explanation:

The Empirical Rule(68-95-99.7 rule) states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 267

Standard deviation = 19

(a) Between what values do the lengths of the middle 95% of all pregnancies fall?_____________and___________days

By the Empirical rule, 95% of all pregnancies fall within 2 standard deviations of the mean.

So

267 - 2*19 = 229 days

to

267 + 2*19 = 305 days

(b) How short are the shortest 2.5% of all pregnancies?______days or less

95% of all pregnancies fall within 2 standard deviations of the mean. The other 5% are more than 2 standard deviations from the mean. Since the distribution is symmetric, 2.5% is more than 2 standard deviations below the mean(shortest 2.5%) and 2.5% is more than 2 standard deviations above the mean(longest 2.5%). So

267 - 2*19 = 229 days

c) How long do the longest 2.5% of pregnancies last?________days or more

Explanation in b)

267 + 2*19 = 305 days

40% of the children in a sports club play badminton. 25% of the children who play badminton also play squash. There are 11 child
Keith_Richards [23]

Answer:

There are 110 children total in the sports club

Step-by-step explanation:

To get this answer, its actually easier than it seems. You might need a calculator however.

First you start with the 11 children who play both badminton and squash, then, you divide that by 0.25 (25%) to get 44.

Next you take 44 and divide it by 0.4 (40%) to get 110.

And there you go! If you want to make sure you got it right simply start with 110 and multiply it by 0.4 then multiply the number/decimal you get by 0.25. You should get 11 to confirm your answer :)
