How do you know whether a number is a multiple of another number

1 answer:

3 0

You would know when one number is also a multiple when the other number is a factor of it as well. For example when we see a prime number like 2, there are no factors for this number so it is just a multiple of 1 and 2.
However for numbers like 15 and 25.
We would know ( if you have your times tables memorized) that 15 is a multiple of 1,3, and 5 and 15. 25 is a multiple of 1, 5, and 25.

Answer:

a) 0.30854

b) 0.21186

c) 0.23468

Step-by-step explanation:

Mario's Pizza delivers pizzas within a 10-mile radius of the restaurant. Their delivery times are Normally distributed with a mean delivery time of 30 minutes and a standard deviation of 10 minutes.

We solve using z score formula.

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation.

Find the probability that a randomly selected customer will have to wait

a) less than 25 minutes

for x < 25 minutes

z = 25 - 30/10

z = -0.5

Probability value from Z-Table:

P(x<25) = 0.30854

b) more than 38 minutes

For x > 38 minutes

z = 38 - 30/10

z = 0.8

Probability value from Z-Table:

P(x<38) = 0.78814

P(x>38) = 1 - P(x<38) = 0.21186

c) between 26 and 32 minutes

For x = 26 minutes

z = 26 - 30/10

z = -0.4

Probability value from Z-Table:

P(x = 26) = 0.34458

For x = 32 minutes

z = 32 - 30/10

z = 0.2

Probability value from Z-Table:

P(x = 32) = 0.57926

The probability that a randomly selected customer will have to wait between 26 and 32 minutes is calculated as:

P(x = 32) - P(x = 26)

= 0.57926 - 0.34458

= 0.23468

H(t) = -16t2 + 160t + 384 rewrite in factored form

stiks02 [169]

h(t) = -16t^2 + 160t + 384 Rewritten in factored form is 16(−t−2)(t−12).

Create a proportion using the form %/100 = is/of to represent the following word problem. 15 is 1 1/2% of what number?

Tema [17]

Let the required number be x, then to create a proportion using the form
$\frac{\%}{100} = \frac{is}{of}$

Thus, let 15 be $1 \frac{1}{2} \%$ of x, then
$\frac{1 \frac{1}{2}}{100} = \frac{15}{x} \\ \\ \frac{ \frac{3}{2} }{100} =\frac{15}{x} \\ \\ \frac{3}{2}x=1,500 \\ \\ x= \frac{1,500\times2}{3} =1,000$

Therefore, 15 is <span> $1 \frac{1}{2} \%$ of</span> 1,000
