How is a function different from a relation in math

1 answer:

6 0

In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output.

A relation consists of two sets of elements called inputs and outputs, where the input is related to the output in some way.

Which of the following are equations for the line shown below? Check all that

Maurinko [17]

ANSWER: A & B

FOR COORDINATES (2,2)
A) 2-2=-0.25(2-2)
0=0
B) 2-3=-0.25(2+2)
-1=-1

FOR COORDINATES (-2,3)
A) 3-2=-0.25(-2-2)
1=1
B) 3-3=-0.25(-2+2)
0=0

WHY ITS NOT C and D

COORDINATES (2,2)
C) 2+3=-0.25(2-2)
5=0 ZERO DOES NOT EQUAL 5
D) 2-3=-0.25(2-2)
-1=0 ZERO DOES NOT EQUAL -1

COORDINATES (-2,3)
C) 3+3=-0.25(-2-2)
6=1 SIX DOES NOT EQUAL 1
D) 3-3=-0.25(-2-2)
0=1 ZERO DOES NOT EQUAL 1

Pennies made prior to 1982 were made of 95% copper. Because of their copper content, these pennies are worth about $0.023 each.

aleksklad [387]

Using the z-distribution, it is found that since the test statistic is less than the critical value for the right-tailed test, it is found that this does not provide convincing evidence that the proportion of pennies in her containers that are pre-1982 copper pennies is greater than 0.132.

At the null hypothesis, it is tested if the proportion of pennies in her containers that are pre-1982 copper pennies not greater than 0.132, that is:

$H_0: p \leq 0.132$

At the alternative hypothesis, it is tested if it is greater, that is:

$H_1: p > 0.132$

The test statistic is given by:

$z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}$

In which:

$\overline{p}$ is the sample proportion.

p is the proportion tested at the null hypothesis.

n is the sample size.

In this problem, the parameters are:

$p = 0.132, n = 50, \overline{p} = \frac{11}{50} = 0.22$

Hence, the value of the test statistic is given by:

$z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}$

$z = \frac{0.22 - 0.132}{\sqrt{\frac{0.5(0.5)}{50}}}$

$z = 1.24$

The critical value for a right-tailed test, as we are testing if the proportion is greater than a value, using a 0.05 significance level, is of $z^{\ast} = 1.645$ .

Since the test statistic is less than the critical value for the right-tailed test, it is found that this does not provide convincing evidence that the proportion of pennies in her containers that are pre-1982 copper pennies is greater than 0.132.

Clare knows that Priya has a bunch of nickels and dimes in her pocket and that the total amount is $1.25. Find one possibility f

jeka57 [31]

Answer:5x + 10y = 125

Step-by-step explanation

Number of nickel = x

Number of dime = y

Nickel = 5 cent

Dime = 10 cent

Total value = $1.25

Total value should be converted to cent since both dime and nickel are both in cent

= $1.25 * 100 = 125 cents

Therefore,

5x + 10y = 125 cents
