Birth weights in the United States are normally distributed with a mean of 3420 g and a standard deviation of 495 g. The Newport

Answer:

$P(2450$

And we can find this probability with this difference:

$P(-1.96$

If we use the normal standard table or excel we got:

$P(-1.96$

And that represent 95% of the data. so then the percentage below 2450 is 2.5% and above 4390 is 2.5 %

Step-by-step explanation:

Let X the random variable that represent the birth weights of a population, and for this case we know the distribution for X is given by:

$X \sim N(3420,495)$

Where $\mu=3420$ and $\sigma=495$

We are interested on this probability

$P(2450$

And we can use the z score formula given byÑ

$z=\frac{x-\mu}{\sigma}$

If we apply this formula to our probability we got this:

$P(2450$

And we can find this probability with this difference:

$P(-1.96$

If we use the normal standard table or excel we got:

$P(-1.96$

And that represent 95% of the data. so then the percentage below 2450 is 2.5% and above 4390 is 2.5 %

Find the equation of the line with slope 3/7 and that passes through the point (14, 0). Write your answer in the form y = mx + b

Allushta [10]

Answer:

y = 3/7x - 6

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Algebra I

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define

Slope m = 3/7

Point (14, 0)

Step 2: Find y-intercept b

Substitute: 0 = 3/7(14) + b
Multiply: 0 = 6 + b
Isolate b: -6 = b
Rewrite: b = -6

Step 3: Write linear equation

y = 3/7x - 6

Complete Question

A baseball team had $1,000 to spend on supplies. The team spent $185 on a new bat. New baseballs cost $4 each.

The inequality 185 + 4b ≤ 1,000 can be used to determine the number of new baseballs (b) that the team can

purchase. Which statement about the number of new baseballs that can be purchased is true?

A. The team can purchase 204 new baseballs.

B. The minimum number of new baseballs that can be purchased is 185.

C. The maximum number of new baseballs that can be purchased is 185.

D. The team can purchase 185 new baseballs, but this number is neither the

maximum nor the minimum.

Answer:

D. The team can purchase 185 new baseballs, but this number is neither the maximum nor the minimum.

Step-by-step explanation:

The first step would be to solve the given equation:

185 + 4b ≤ 1000

4b ≤ 1000 - 185

4b ≤ 815

Divide both sides by 4

b ≤ 203.75

The maximum amount of baseballs the team can buy is 203. This means that they can buy 203 or less than that amount.

Of all the options give, option D is the correct option because the team can purchase 185 new baseballs, but this number is neither the maximum nor the minimum.

The maximum number of ball they can buy is 203 balls and the minimum is zero.
