Answer:

D. No, the elements of the set of y are not all ordered pairs.

Step-by-step explanation:

Answer A. looks plausible: There are a few ordered pairs in this list, but that is not good enough.

All elements of the set should be ordered pairs and that is not the case. So answer D is correct.

How do you simplify 16+(f+4)

kenny6666 [7]

First you have to simply distribute the + through the parentheses

16+f+4

Then you combine like terms (in this case the 16 and the 4)

f+20

16+(f+4) simplified is f+20

Hope this helps!!

Marianna [84]

Hello!

130 ounces is about 4 quarts so 5 quarts is larger

130 ounces is slightly above 16 cups so 16 cups is lower

130 ounces is about 8 pints so 9 pints is larger

130 ounces is slightly above a gallon so 2 gallons is larger

130 ounces is slightly above a gallon so 1 gallon is smaller

The answers are A) 5 quarts, C) 9 pints, and D) 2 gallons

The number of errors in a textbook follow a poisson distribution with a mean of 0.01 errors per page. what is the probability th

neonofarm [45]

Mean number of errors in each page = 0.01
Mean number of errors in 100 pages = 0.01*100=1

It is possible to use the cumulative distribution function (CMF), but the math is a little more complex, involving the gamma-function. Tables and software are available for that purpose.

Thus it is easier to evaluate with a calculator for the individual cases of k=0,1,2 and 3.

The Poisson distribution has a PMF (probability mass function)

$P(k):=\frac{\lambda^ke^{-\lambda}}{k!}$
with λ = 1
=>
$P(0):=\frac{1^0e^{-1}}{0!}=0.3678794$
$P(1):=\frac{1^1e^{-1}}{1!}=0.3678794$
$P(2):=\frac{1^2e^{-1}}{2!}=0.1839397$
$P(3):=\frac{1^3e^{-1}}{3!}=0.0613132$
=>
$P(k$
or
P(k<=3)=0.9810 (to four decimal places)

A grandsons age in years is equal to his grandfather's age in years. The difference of the grandsons age in years and the grandf

garik1379 [7]

The age of the grandson is 7 years and the grandfather is 84 years if the grandson's age in months is equal to the age of grandpa in years and the difference in age is 77.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Let's suppose the age of the grandsons is x years and

age of the grandfather's age is y years

Here some data are misprinted, so we are assuming the grandson's age in months is equal to the age of grandpa in years and the difference in age is 77.

Then according to the problem:

12x = y (as in 1 year, there are 12 months)

y -x = 77 (as difference in age is 77)

After solving both equations, we get:

x = 7 years and y = 84 years

Thus, the age of the grandson is 7 years and the grandfather is 84 years if the grandson's age in months is equal to the age of grandpa in years and the difference in age is 77.
