Answer:

To find the volume of a cube one must multiply all three dimensions together. Here we know two of the dimensions and the volume but not the third dimension. First I multipl together to two known dimensions: 3/4 x 1/2 = 3/8. Next I divide the volume by this answer by using the reciprocal of 3/8 and multipling. 21/32 x 8/3 = 7/4 by cancelling the 32 with the 8 and the 21 with the 3. Now 7/4 must be changed into a mixed number. Divide the numerator by the denominator and write the remainder as a fraction. 7/4 = 1 3/4.

What times what equals 29 besides 29 times 1
Feliz [49]
<span>The answer is 1 times 29. Number 29 is a prime number, which means that its multiples are 1 and itself (29). 29 = 29 * 1. According to the commutative law, in addition and multiplication, numbers can be swapped but the result will remain the same: a+b=b+a or a*b=b*a. Therefore, 29 = 29 * 1 = 1 * 29. In other words, 29 times 1 equals 29 and 1 times 29 equals 29, too.</span>

Telemarketing. the probability that a call will reach a live person is 0.2. the calls are independent. (a) a telemarketer places
Sergeeva-Olga [200]

Solution: Telemarketing. the probability that a call will reach a live person is 0.2. the calls are independent. (a) a telemarketer places 5 calls. what is the probability that none of them reaches a live person.

Answer: The given random experiment can be considered as binomial experiment with probability of success = 0.2 and number of trials = 5

Therefore, we have:

n=5,p=0.2,q=(1-p)=1-0.2=0.8

Let x be the number calls that reach to live person.

We have to find P(x=0)

Using the binomial probability distribution, we have:

P(x=0)=\binom{5}{0}0.2^{0} (1-0.2)^{5-0}

                 =1 \times 1 \times 0.8^{5}

                 =0.3277

Therefore, the probability that none of them reaches a live person is 0.3277
