For this case we have that an identity is an equation in which the left side of the equation is equal to the right side of the equation.

We then have the following equation:

2x + 3 = \frac {1} {2} (4x + 2) + 2

When applying the distributive property on the right side we have:

2x + 3 = \frac {1} {2} (4x) + \frac {1} {2} (2) + 2

Rewriting we have:

2x + 3 = 2x + 1 + 2\\2x + 3 = 2x + 3

We observe that both sides are equal. Therefore, the equation is an identity.

Answer:

2x + 3 = \frac {1} {2} (4x + 2) + 2

Option C

A food scientist takes a random sample of 25 cereals in order to test the claim that the mean fiber content is less than 2.5 gra
Jlenok [28]

Answer:

Choice A: there is insufficient evidence to conclude that the mean for the fiber content is less than 2.5 gms.

Step-by-step explanation:

From the graphs given the more appropriate is one sample t- test

One sample t- test is used and the results are

Hypothesis Test                       Fiber

Sample Mean                          2.62

Sample St. Dev                       3.492

Degrees of Freedom              24

t- test statistic                         0.1718

p- value                                    0.5675

the critical region for this test at ∝= 0.05 is t < -1.711

There is not enough evidence to reject the null hypothesis.

Since the calculated t=   0.1718 does not fall in the critical region the null hypothesis is accepted that the mean fiber content is not  less than 2.5 grams.T

Sean and sarah spend $70 a month eating out how much money would they have after 15 years if they invested the money instead at
SpyIntel [72]

Answer:

Future Value= $17,170.12

Step-by-step explanation:

Giving the following information:

Monthly deposit (A)= $70

Interest rate (i)= 0.04/12= 0.0033

Number of periods (n)= 15*12= 180 months

<u>To calculate the future value (amount saved), we need to use the following formula:</u>

FV= {A*[(1+i)^n-1]}/i

A= monthly deposit

FV= {70*[(1.0033^180) - 1]} / 0.0033

FV= $17,170.12
