A survey found that 68% of students do their homework before 10:00 P.M. Predict how many students out of 1,095 do their homework before 10:00 P.M.

Answers

Answer 1

Answer:

744.6 or if you round it 745

Step-by-step explanation:

Step 1: Divide 1095 by 100

In this case, the number that we are "comparing" to 100 is 1095, so we must first normalize the number by dividing it by 100. The operation we have to solve is this:

1095/100= 1095÷100= 10.95

Step 2: Multiply 10.95 by 68 to get the solution

Now that we have our normalized number, 10.95, we just have to multiply it by 68 to get our final answer. The forumla for this is obviously quite simple:

10.95×68= 744.6

Explain how to solve the equation and how to check the
solution.


40 = 8y

Answers

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.

Find the sum or difference. 9/12 - 7/12 *

Answers

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:

Convert both fractions to have a common denominator. In this case, the common denominator is 12, so you can rewrite both fractions as follows: 9/12 - 7/12 = (9/12) - (7/12) = (9 - 7)/12 = 2/12Simplify the fraction if possible. In this case, you can simplify 2/12 to 1/6 by dividing both the numerator and denominator by 2: 2/12 = (2/2) / (12/2) = 1/6The sum or difference is 1/6.

So the answer is 1/6.

For the linear function, y increases by a
of 3 each time x increases by 1.
For the exponential function, y increases by a(n)
of 3.

Answers

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.

t=

Answers

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.

9) A quotient is a result of dividing a quantity by another quantity. We see that 45 ÷ 9 is a form of division. We could say that 45 is divided into 9 parts. 45 ÷ 9  can also be written in fractional form: [tex]\frac{45}{9}[/tex]. Lastly, we see that the quotient would be 5.

10) A product is a result of multiplying a quantity by another quantity. We see that 7.6s is a simplified form of multiplication that actually represents 7.6 × s.

Questão 11 - Um investidor aplicou
a quantia de R$ 500,00 em um fundo
de investimento que opera no regime
de juros simples. Após 6 meses o
investidor verificou que o montante
era de R$ 560,00. Qual a taxa de
juros desse fundo de investimento?

Answers

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.
