What is $0.1369 rounded to the nearest cent

makvit [3.9K]

Ok, what is $0.1369 rounded to the nearest cent?

100 cents make a dollar which means the most possible cents not making a dollar is 99 cents

So that means you leave the first two decimals alone and focus on the last two.

What is 69 closer to? 70 or 60? Well, its larger than 65 which is the halfway point so its closer to 70

Is 70 closer to 0 or 100? Well, since 70 is past the halfway point which is 50, its closer to 100.

Think of 3 as 0 and the next number up which is 4 as 100, well, since 70 is closer to 100 than 0, its closer to 4.

So That means that 0.1369 rounded to the nearest cent is $0.14

Your answer rounded is $0.14

X²- 12x + a = (x-b)² <br>Find the Value of a and value of b <br>

maxonik [38]

Answer:

a = 36 , b = 6

Step-by-step explanation:

expand the right side using FOIL and compare coefficients with like terms on left side.

(x - b)²

= x² - 2bx + b² , compare to x² - 12x + a , then

- 2b = - 12 ( divide both sides by - 2 )

b = 6

and a = b² = 6² = 36

What is the simplest form of this expression?<br> 4(y + 2) - 2

Semenov [28]

The simplest form is 4y+6?

you distribute the 4 to everything in the parentheses and then combine like terms so you would combine the 8 and -2

People tend to evaluate the quality of their lives relative to others around them (Frieswijk et al., 2004). In one study, resear

Step-by-step explanation:

Hello!

Research.

n=9 frail elderly were interview and compared to a fictitious person who was worse off then the interviewee, a life-satisfaction score was determined for each person.

18, 23, 24, 22, 19, 27, 23, 26, 25

Assuming that the population average score is μ= 20, the researchers think that the elderly in the sample are more or less satisfied than others in the general population.

a. You have the information of one sample, assuming this sample has a normal distribution and each elderly interviewed is independent, then the t-test of choice is a one-sample t-test.

b. and c. If you say that the elderly are "more or less" satisfied than the others, this means that they are either as satisfied as to the general population or not satisfied as to the general population. Symbolically:

H₀: μ = 20

H₁: μ ≠ 20

This is a two-tailed test, meaning, you will have two critical regions.

d.

α: 0.05

Left critical value: $t_{n-1;/\alpha 2} = t_{8; 0.025}= -2.306$

Right critical value: $t_{n-1;1-\alpha /2} = t_{8;0.975} = 2.306$

e.

$t_{H_0}= \frac{X[bar]-Mu}{\frac{S}{\sqrt{n} } } ~t_{n-1}$

X[bar]= 23

S= 3

$t_{H_0}= \frac{23-20}{\frac{3}{\sqrt{9} } }= 3$

f.

Considering that the calculated t-value is greater than the right critical value, the decision is to reject the null hypothesis, so using a significance level of 5% you can conclude that the average life-satisfaction score of the elderly is different than 20.

I hope it helps!
