Answer:

<em>The answer is Domain = {3,2,5,6,0} and Range =  {2,4,-3,-7,0}</em>

Step-by-step explanation:

    We have given some points such as (3,2)(2, 4) (5,-3) (6.-7) (0,0)

    As we know as the definition of domain is

    Domain means the input value we are giving to the function is known to

    be the domain of the function

    such that y = f(x) .................................................................. (1)

    where x is the domain

    Range means the output value of the corresponding input such as in

    equation (1) we get y value as value of range

    Domain of the given problem is {3,2,5,6,0}

    Range of the given problem is {2,4,-3,-7,0}

    <em>The answer is Domain = {3,2,5,6,0} and Range =  {2,4,-3,-7,0}</em>

The lengths of pregnancies are normally distributed with a mean of 268 days and a standard deviation of 15 days. If 64 women are
shtirl [24]

Answer:

0.3569 is the probability that they have a mean pregnancy between 266 days and 268 days.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ =  268 days

Standard Deviation, σ =  15 days

We are given that the distribution of lengths of pregnancies is a bell shaped distribution that is a normal distribution.

Formula:

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

Standard error due to sampling =

\displaystyle\frac{\sigma}{\sqrt{n}} = \frac{15}{\sqrt{64}} = \frac{15}{8}

P(pregnancy between 266 days and 268 days)

P(266 \leq x \leq 268) = P(\displaystyle\frac{266 - 268}{\frac{15}{8}} \leq z \leq \displaystyle\frac{268-268}{\frac{15}{8}}) = P(-1.0667 \leq z \leq 0)\\\\= P(z \leq 0) - P(z < -1.067)\\= 0.5000 - 0.1431 = 0.3569 = 35.69\%

P(266 \leq x \leq 268) = 35.69\%

Kurt has $9,000 in an account. The interest rate is 5% compounded annually. To the nearest cent, how much will he have in 1 year
jekas [21]

Answer:

$9450

Step-by-step explanation:

Answer:

A = $9,450.00

A = P + I where

P (principal) = $9,000.00

I (interest) = $450.00

Calculation Steps:

First, convert R as a percent to r as a decimal

r = R/100

r = 5/100

r = 0.05 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 9,000.00(1 + 0.05/1)(1)(1)

A = 9,000.00(1 + 0.05)(1)

A = $9,450.00

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $9,000.00 at a rate of 5% per year compounded 1 times per year over 1 years is $9,450.00.

X^2 - 18x + 81 = 0 x=?
levacccp [35]

Answer:

x = 9

Step-by-step explanation:

Solve for x:

x^2 - 18 x + 81 = 0

Write the left hand side as a square:

(x - 9)^2 = 0

Take the square root of both sides:

x - 9 = 0

Add 9 to both sides:

Answer:  x = 9
