it’s d because...
you have to insert the x and y values for x and y.
So, (-2,-4) put into y=3x+2 is -4=3(-2)+2
then solve to see if it is right...
-4=3(-2)+2
-4=-6+2
-4=-4

The book store earned x dollars in profit. Last week, the total profit
increased by 5%. Which expression represents the book store's total
increase in profit?

Answers

Answer:

x + 0.05x

Step-by-step explanation:

Given

Earnings earned by the bookstore = x

percentage increase = 5%

Increment = 5% of x

Increment = 0.05x

book store's total increase in profit = Original earning + increment

book store's total increase in profit x + 0.05x

Hence the expression that represents the book store's total increase in profit is x + 0.05x

If the decision is to reject the null hypothesis of no difference between two population proportions at the 5% level of significance, what are the alternative hypothesis and rejection region?

Answers

Answer:

The alternative hypothesis is

[tex]H_a : p_1 \ne \ p_2[/tex]

The rejection region is the region outside the interval

[tex]-1.96 < z_{critical} < 1.96[/tex]

Step-by-step explanation:

From the question we are told that

The significance level is [tex]\alpha = 0.05[/tex]

The null hypothesis is [tex]H_o : p_1 = p_2[/tex]

The alternative hypothesis is [tex]H_a : p_1 \ne \ p_2[/tex]

Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is

[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]

Hence the rejection region is the region outside the interval [tex]-1.96 < z_{critical} < 1.96[/tex]

The alternative hypothesis is, [tex]H _a; \ P_1\neq P_2[/tex] .

And the rejection region is the region outside the interval is [tex]-1.96< Z_c_r_i_t_i_c_a_l <1.96[/tex] .

Given that,

If the decision is to reject the null hypothesis of no difference between two population proportions at the 5% level of significance.

We have to determine,

What is the alternative hypothesis and rejection region?

According to the question,

The significance level is, [tex]\alpha = 5 \ percent = 0.05[/tex]

The null hypothesis is [tex]H_0 ; P_1 = P_2[/tex]

The alternative hypothesis is, [tex]H _a; \ P_1\neq P_2[/tex]

In the normal distribution table, the critical value [tex]\dfrac{\alpha}{2}[/tex] is,

[tex]Z _\frac{\alpha}{2} = 1.96[/tex]

Hence, the rejection region is the region outside the interval is [tex]-1.96< Z_c_r_i_t_i_c_a_l <1.96[/tex] .

A survey showed that 70% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. If 7 adults are randomly selected, find the probability that exactly 2 of them need correction for their eyesight.

Answers

Answer:

0.0250047

Step-by-step explanation:

Given that :

Proportion who need correction glasses = 70%

Number of trials = 7

Probability that exactly 2 needs correction glasses :

Using a binomial probability formula :

P(success) = p = proportion who need glasses = 0.7

P(x =x) = nCr * p^x * (1 - p)^(n - x)

P(x = 2) = 7C2 * 0.7^2 * 0.3^(7 - 2)

P(x = 2) = 7C2 * 0.7^2 * 0.3^5

P(x = 2) = 21 * 0.49 * 0.00243

P(x = 2) = 0.0250047

Answers

Complete Question

If the p-value for your test statistic in a test of hypothesis (for example, a t-test, one-tail) is 0.07 and the significance level alpha is set at 0.05, you conclude that:

Both hypotheses H0 and H1 can be accepted

The null hypothesis H0 cannot be rejected

The null hypothesis H0 can be rejected

The research hypothesis H1 can be accepted

Answer:

The correct option is B

Step-by-step explanation:

From the question we are told that

The p-value is [tex]p-value = 0.07[/tex]

The level of significance is [tex]\alpha = 0.05[/tex]

Generally given that it is a one tail test then the possible value of

The null hypothesis is [tex]H_o : \mu = x[/tex]

Here [tex]\mu[/tex] is the mean and x is the value

the possible values of the alternative hypothesis is [tex]\mu > x \ \ or \ \ \mu < x[/tex]

Now from the value given we see that the [tex]p-value > \alpha[/tex] hence

3. Jada can bake 12 cookies in 20 minutes. How many cookies can she bake 1
in 6 hours? HINT: 20 minutes and 6 hours are not equal, the hours MUST be
turned to minutes.

Answers

Answer:

she can bake 216 cookies in 360 minutes

Step-by-step explanation:

Answer:

Jada can bake 216 cookies in 6 hours.

Step-by-step explanation:

We need to know how many she can cook in 6 hours.

She currently bakes 12 every 20 minutes

we know that 1 hour is 60 minutes.

So we multiply 12 by 3 to get 36 because we know 60 minutes divided by 20 minutes is 3 minutes.

Now we know that she bakes 36 cookies in 1 hour

But it asked for 6 hours so simple multiplication:

36 cookies per 1 hour X 6 hours

36X6= 216
