Answer:

t = -1.54.

Step-by-step explanation:

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

H0:μ=54.5

This means that [tex]\mu = 54.5[/tex]

Your sample consists of 48 subjects, with a mean of 54.1 and standard deviation of 1.8.

This means, respectively, that [tex]n = 48, \mu = 54.1, \sigma = 1.8[/tex]

Test statistic

[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]t = \frac{54.1 - 54.5}{\frac{1.8}{\sqrt{48}}}[/tex]

[tex]t = -1.54[/tex]

The test statistic is t = -1.54.

Answer:

[tex]1 \frac{1}{2}[/tex]

Answer:

A taxa de juros desse fundo de investimento é de 24% ao ano.

Step-by-step explanation:

Esta é uma questão que envolve juros simples.

A quantidade de juros acumulados depois de t anos é dado por:

[tex]J = P*r*t[/tex]

Em que P é o investimento inicial, r é a taxa de juros, é t é o tempo, em anos.

O montante é dado por:

[tex]M = J + P[/tex]

Um investidor aplicou a quantia de R$ 500,00.

Isso significa que [tex]P = 500[/tex]

Juros acumulados:

Montante era de R$ 560,00, o que significa que [tex]M = 560[/tex]

Então, a quantidade de juros acumulados é dada por:

[tex]M = J + P[/tex]

[tex]J = M - P = 560 - 500 = 60[/tex]

Taxa de Juros:

6 meses é meio ano, o que implica que [tex]t = 0.5[/tex]

Então

[tex]J = P*r*t[/tex]

[tex]60 = 500*r*0.5[/tex]

[tex]250r = 60[/tex]

[tex]r = \frac{60}{250}[/tex]

[tex]r = 0.24[/tex]

A taxa de juros desse fundo de investimento é de 24% ao ano.

Answer:

Bro this is hard answer is 0.17 or 2/12

Step-by-step explanation:

9/12 - 7/12

9 - 7 first since they both have 12 as their denominator

2 is the answer so you get 2/12

To find the sum or difference of 9/12 - 7/12, you can follow these steps:

So the answer is 1/6.

Answer:y=5

Step-by-step explanation:

To find out what y is you have to do the inverse to 'undo' the equation.

So instead of multiplying y by 8 you have to divide 40 by 8.

40÷8=5

So y=5

You can check your answer by putting 5 where y is.

40=8×5

Hope this helps :)

Answer:

Use the inverse operation to isolate the variable. Undo multiplication by dividing by 8 on both sides of the equation. Simplify by completing the divisions, 40 ÷ 8 = 5, and 8 ÷ 8 = 1. The solution is y = 5. Check the solution by substituting 5 for y in the original equation, and then simplify. 8 × 5 = 40 and 40 = 40 is a true statement, so 5 is the solution.

Answer:

3x

Step-by-step explanation:

if  __ + 3 = 15   and x=4  then you need to find what plus 3 = 15.

12+3 = 15, and to get from 4 to 12 you multiply by 3

3x + 3 = 15! hope that helps

Answer:

  (d) ∅

Step-by-step explanation:

Subtracting y from both sides gives ...

  4 = -5

There is no value of y that will make this true. There is no solution to the equation.

The solution set is the null set: ∅.

Answer:

3/2 and 3/4 are both not multiples of 1/3.

Step-by-step explanation:

They have to have 3 as the denominator (or the number below the line) to be a multiple of 1/3. For example: 1/3, 2/3, 3/3.

Hope you understand that! :)

Answer:

Explanation Below :)

Step-by-step explanation:

3/2 & 3/4 are mistakes

When finding three multiples of a number that is a fraction, the denominator (bottom number) always stays the same. So, 3/2 & 3/4 are not multiples of 1/3.

Answer:

Step-by-step explanation:

Hi,

Describe the slope: This is a horizontal line. Slope measures the steepness of a line, since this is a horizontal line with no change whatsoever, the slope must be 0.

Calculate: (-1,-2) (3,-2)

Change in y over change in x

-2 - (-2) = 0

3 - 1 = 2

0/2 = 0

The slope is 0

Kendra has $5.35 in nickels and quarters. If she has 13 more quarters than nickels, how many of each coin does she have?

(Scroll Down for Answer!)

We know that n = q - 13.

The value equation is

5n + 25q = 535 (we work in cents)

Now substitute for n and get

5(q - 13) + 25q = 535

5q - 65 + 25q = 535

30q = 600

q = 20 so that

n = 7

Answer:

D, -42 multiply 6 on both sides

D. because when it is multiplied, the inequality is no longer true.

Answer:

0.074

Step-by-step explanation:

convert 7.4% to a decimal.

Answer:

The linear equation is:

y = 3*x

when x = 1

y = 3*1 = 3

when x = 2

y = 3*2 = 6

Then as x increases one unit, y increases 3 units.

Then the correct statement would be something like:

"For the linear function, y increases by a sum of 3 each time x increases 1"

The exponential function is:

y = 3^x

When x = 1

y = 3^1 = 3

When x = 2

y = 3^2 = 3*3

when x = 3

y = 3^3 = 3*3*3

So when x increases by 1, we multiply the previous value of y by 3.

Then the correct sentence is something like:

"For the exponential function, y increases by a factor of 3".

Answer: for the linear function y increases by a difference

for the exponential function y increases by a(n) ratio.
