#1.) The girl would have $37 left. [EXPLANATION YOU MOST LIKELY NOT USE OR CARE ABOUT]: Zaria spent 18 bucks after 2 days on vacation. According to what I know from that, she spent about 9 dollars each day. So, if you add 5 more days to that, along with the fact that she’s spending 9 dollars a day, 9x5 equals 45. In 5 days she spent 45 bucks, add the 45 bucks with 18 bucks, you’ll get 63. $63 dollars spent after 7 days of vacation. Now they said, how much she’ll have LEFT, soooo, 100-63= 37 DOLLARS. BOOM... your welcome

Factors and Multiples. But they both involve multiplication: Factors are what we can multiply to get the number. Multiples are what we get after multiplying the number by an integer (not a fraction).

A particular employee arrives at work sometime between 8:00 a.m. and 8:30 a.m. Based on past experience the company has determin
Gala2k [10]

Answer:

0.3333 = 33.33% probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value between c and d is given by:

P(c \leq X \leq d) = \frac{d - c}{b - a}

A particular employee arrives at work sometime between 8:00 a.m. and 8:30 a.m.

We can consider 8 am = 0, and 8:30 am  = 30, so a = 0, b = 30

Find the probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Between 15 and 25, so:

P(15 \leq X \leq 25) = \frac{25 - 15}{30 - 0} = 0.3333

0.3333 = 33.33% probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Three numbers between 80 and 100 are prime numbers. What numbers are they? Eight numbers between 31 and 41 are composite numbers
Flura [38]
83, 89, and 97 are three primes between 80 and 100.

The primes between 30 and 50 are 31, 37, 41, 43, and 47, all of which are odd.  All other numbers between 30 and 50 are composite.

To mentally find 2*50*25, you could either first multiply 25 by 2, to get 50*50, which can easily be calculated as 2500, or you could multiply the 50 by 2, for a result of 100*25, which is clearly also 2500.
