Answer:

The answer to your question is letter C

Step-by-step explanation:

Process

1.- Find two points of the line

A ( 0, 1)

B ( 1, -3)

2.- Find the slope of the line

$m = \frac{y2 - y1}{x2 - x1}$

$m = \frac{-3 - 1}{1 - 0}$

$m = \frac{-4}{1}$

m = -4

3.- Find the equation of the line

y - y1 = m (x - x1)

y - 1 = -4( x - 0)

y -1 = -4x

y = -4x + 1

Answer:

He will need 4 newborns in the sample to be 95% confident.

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.9}{2} = 0.05$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.05 = 0.95$ , so $z = 1.645$

Now, find the margin of error M as such

$M = z*\sqrt{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the length of the sample.

So:

$646 = 1.645*\frac{746}{\sqrt{n}}$

$646\sqrt{n} = 1227.17$

$\sqrt{n} = 1.90$

$\sqrt{n}^{2} = (1.90)^{2}$

$n = 3.61$

He will need 4 newborns in the sample to be 95% confident.

In 2002, there were 972 students enrolled at Oakview High School. Since then, the number of students has increased by 1.5% each

Answer:

The number of student increased each year by 986.58.

Step-by-step explanation:

Given : In 2002, there were 972 students enrolled at Oakview High School.

To find : The number of students has increased by 1.5% each year ?

Solution :

Using the exponential growth function,

$P(t)=P_o(1+r)^t$

Here, $P_o=972$ is the initial population

r=1.5%=0.015 is the rate

t=1 time

$P(t)=972(1+0.015)^1$

$P(t)=972(1.015)$

$P(t)=986.58$

i.e. the number of student increased each year by 986.58.
