I started with c, but you could’ve started with any box.

So I took the numbers in the c box (the black box in my picture) and divided to see which were multiples of two. They all were.

Then I went to a. All of a’s numbers were divisible by 7.

Then b. Two of them are divisible by 2, so that’s not the answer. None of them were divisible by 7, so there’s your answer!

Then d. Two are divisible by 7, so your rules is divisible by 2.

I hope this helps!

UkoKoshka [18]

Answer:

The probability that 8 mice are​ required is 0.2428.

Step-by-step explanation:

Given : A scientist inoculates​ mice, one at a​ time, with a disease germ until he finds 3 that have contracted the disease. If the probability of contracting the disease is two sevenths.

To find : What is the probability that 8 mice are​ required? The probability that that 8 mice are required is nothing ?

Solution :

Applying binomial distribution,

P(X=r)=^nC_r p^rq^{n-r}

Where, p is the probability of success p=\frac{2}{7}

q is the probability of failure q=1-p, q=1-\frac{2}{7}=\frac{5}{7}

n is total number of trials n=8

r=3

Substitute the values,

P(X=3)=^8C_3 (\frac{2}{7})^3 (\frac{5}{7})^{8-3}

P(X=3)=\frac{8!}{3!5!}\times \frac{8}{343}\times (\frac{5}{7})^{5}

P(X=3)=\frac{8\times 7\times 6}{3\times 2\times 1}\times \frac{8}{343}\times \frac{3125}{16807}

P(X=3)=0.2428

Therefore, the probability that 8 mice are​ required is 0.2428.

2) 23 and 24 are complementary angles. If m 23 = (x + 24)º and m 24 = (x )º, then
adoni [48]

Answer:

m<23 = 57° & m<24= 33°

Step-by-step explanation:

You have to create an equation that equals 90°.

(x+24)+x=90

2x+24=90

2x=66

x=33

m<23 = 33+24= 57° so m<23= 57°

m<24= 33°

In the year 2000 the population of Mexico was about 100 million, and it was growing by 1.53% per year. At this growth rate, the
andre [41]

Answer:

11 years

Step-by-step explanation:

Set the function f(x) = 100(1.0153)^x = to 118 and solve for x:

100(1.0153)^x = 118

Taking the natural logarithm of both sides, we get:

ln 100 + x ln 1.0153 = ln 118

Then x ln 1.0153 = ln 118 - ln 100, or

                           = 4.7707 - 4.6052

    ... which leads to:

                                4.7707 - 4.6052

                         x = ---------------------------   =  11 years (rounded up from 10.888 )

                                     0.0152
