so X equals -3 so when you put that in the three becomes positive because of the negative sign on the X and then +5 equals 8

There are 12 apples in total.

Step-by-step explanation:

If Anne gave Ben 6 apples then heres how:

2:3 subrtact 6 apples = 1:3

6 apples x 2 = 12 apples =

2 ÷ 2 = 1

Hence, your answer is double 6 which is 12 apples.

Use the fact that the world population was 2560 million in 1950 and 3040 million in 1960 to model the population of the world in

Radda [10]

Answer:

Let the growth function that shows the population in millions after x years,

$P=P_0(1+r)^x$

Where,

$P_0$ = initial population,

r = growth rate per year,

Suppose the population is estimated since 1950,

Thus, if x = 0, P = 2560,

$\implies 2560 = P_0 (1+r)^0\implies P_0 = 2560$

Now, if x = 10 ( that is, on 1960 ), P = 3040,

$3040=2560(1+r)^{10}\implies r = 0.017$

Hence, the required function that shows the population after x years,

$P=2560(1.017)^x$

If x = 42,

The population in 1992 would be,

$P=2560(1.017)^{42}\approx 5196.608365\text{ millions}$

if x = 80,

The population in 2030 would be,

$P=2560(1.017)^{80}\approx 9860.891929\text{ millions}$

Suppose that time spent on hold per call with customer service at a large telecom company is normally distributed with a mean µ

lana66690 [7]

Answer:

0.3108 is the probability that the sample mean is between 7.8 and 8.2 minutes.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 8 minutes

Standard Deviation, σ = 2.5 minutes

Sample size, n = 25

We are given that the distribution of time spent is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

Standard error due to sampling =

$=\dfrac{\sigma}{\sqrt{n}} = \dfrac{2.5}{\sqrt{25}} = 0.5$

P(sample mean is between 7.8 and 8.2 minutes)

$P(7.8 \leq x \leq 8.2)\\\\ = P(\displaystyle\frac{7.8 - 8}{0.5} \leq z \leq \displaystyle\frac{8.2-8}{0.5})\\\\ = P(-0.4 \leq z \leq 0.4})\\\\= P(z < 0.4) - P(z < -0.4)\\\\= 0.6554 -0.3446= 0.3108$

0.3108 is the probability that the sample mean is between 7.8 and 8.2 minutes.
