Hey there!

First of all, the quotient of a number and 6 means you divide that number by 6.

Let the number be x.

Then, eight more means you add 8:

8+(6÷x)=3

That's the answer.

Hope everything is clear.

Step-by-step explanation:

Answer:

g(x) = x² + 2

Step-by-step explanation:

If we want to shift a function down, we subtract the number we are asked to move outside the function's argument:

⇒ To shift f(x) b units down → f(x) - b

Similarly, in function notation, if we want to shift a function up, we add the number we are asked to move outside the function's argument:

⇒ To shift f(x) b units up → f(x) + b

Given function f(x) = x²

Shift 2 units up ⇒ x² + 2

Therefore, g(x) = x² + 2

Step-by-step explanation:

The percentage of the boys at the book fair is 6%

Percentages are used in mathematics as a decimal ratio expressed in a fraction of 100. It is represented with a symbol known as %.

At a book fair, the ratio of adults to children are:

7 : 3

The total number of people at the book fair = 7 + 3 = 10

The percentage of adults are:

[tex]\mathbf{=\dfrac{7}{10}\times 100\%}[/tex]

= 70% are adults

The percentage of children are:

 [tex]\mathbf{=\dfrac{3}{10}\times 100\%}[/tex]

= 30% are children

However, if from the children, 4 are girls and 1 is a boy.

The total number of children at the fair  = 4 + 1 = 5

The percentage of girls are:

[tex]\mathbf{=\dfrac{4}{5} \times 30\%}[/tex]

= 24%

The percentage of boys at the book fair is:

[tex]\mathbf{=\dfrac{1}{5} \times 30\%}[/tex]

= 6%

Answer:

Step-by-step explanation:

(x +1)² + (x +1)(5x - 3) = (x +1)(x+1) + (x +1)(5x - 3)

(x +10 is the common term. SO, we can take out (x+1)  

                                 =(x +1) [ x + 1 + 5x - 3]

                                 =(x + 1) (x + 5x + 1 - 3)   {Combine like terms}

[tex] x = 20 [/tex]

Step-by-step explanation:

[tex] \frac{3}{5}x - \frac{1}{4}x = 7 [/tex]

The LCD is 20, so multiply both sides of the equation by 20.

[tex] 20(\frac{3}{5}x - \frac{1}{4}x) = 20 \times 7 [/tex]

[tex] 4 \times 3x - 5 \times x = 140 [/tex]

[tex] 12x - 5x = 140 [/tex]

Step-by-step explanation:

Question 1:

In a function, every output value corresponds to exactly one input value.

The words that should be switched around are "output" and "input". This is because every input should have have only ONE output.

Question 2:

The following graph fails the vertical line test and is not a function. (YES)

Using the vertical line test to test whether the vertical line passes through the graphed function more then once. If it does, its not a function. If it doesn't, it is a function. Sadly, the vertical lines pass the point on two separate occasions which makes it not a function.

The vertical line shows gives the points (4, 2) and (4, -2).

Using the t-distribution, as we have the standard deviation for the sample, it is found that it cannot be concluded that the diet has a long-term effect.

At the null hypotheses, it is tested if there is no difference in the weights, that is:

[tex]H_0: \mu_A - \mu_B = 0[/tex]

At the alternative hypotheses, it is tested if the weights decrease, that is:

[tex]H_1: \mu_A - \mu_B < 0[/tex]

Using a calculator, for each sample, we have that:

[tex]\mu_B = 210.8, s_B = 33.85, sE_B = \frac{33.85}{\sqrt{15}} = 8.74[/tex]

[tex]\mu_A = 207.2, s_A = 33.47, sE_A = \frac{33.47}{\sqrt{15}} = 8.64[/tex]

Hence, for the distribution of differences, we have that:

[tex]\overline{x} = \mu_A - \mu_B = 207.2 - 210.8 = -3.6[/tex]

[tex]s = \sqrt{sE_B^2 + sE_A^2} = \sqrt{8.74^2 + 8.64^2} = 12.3[/tex]

It is given by:

[tex]t = \frac{\overline{x} - \mu}{s}[/tex]

In which [tex]\mu = 0[/tex] is the value tested at the null hypothesis.

Then:

[tex]t = \frac{\overline{x} - \mu}{s}[/tex]

[tex]t = \frac{-3.6 - 0}{12.3}[/tex]

[tex]t = -0.29[/tex]

Considering a left-tailed test, as we are testing if the mean is less than a value, with a standard significance level of 0.05 and 15 + 15 - 2 = 28 df, the critical value is of [tex]t^{\ast} = -1.7[/tex].

Since the test statistic is greater than the critical value for the left tailed test, it cannot be concluded that the diet has a long-term effect, as the null hypothesis is not rejected.
