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:

A  

Both hypotheses H0 and H1 can be accepted

B

The null hypothesis H0 cannot be rejected

C

The null hypothesis H0 can be rejected

D

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

The decision rule is  

    Fail to reject  the null hypothesis

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

2:7:1

Also, 2x 7x and 1x or just x

2x+7x+x = 30

10x = 30

x=3

So the three numbers: 2(3):7(3):1(3) OR 6:21:3

Answer:

The discounted price would be 16290 as 18100 times 10 over 100 is 1810 so subtract that from 18100 and you get 16290

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

Step-by-step explanation:

The coefficient of the variable y for the given equation 4 - 2y is -2.

A coefficient is a number that is being multiplied by the variable, i.e. the numerical term with variable, that is a number that is placed before another variable. While the variable represents some quantity, it may also represent a number, a function, etc. The letters a, b, c, x, y, and z are common symbols used for variables.

We have,

An equation 4 - 2y,

So,

In the above-given expression,

We have only one variable and one Constant term,

i.e.

Constant term = 4

And,

Variable term = -2y

So,

In the variable term,

The coefficient of y = -2

So,

The coefficient of y is -2.

Hence, we can say that the coefficient of the variable y in the given equation is -2.

Answer:

Step-by-step explanation:

3x + x + 60 = 180.

first, we add the x's together.

4x + 60 = 180

then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.

x + 15 = 45

then, just subtract 15 from both sides, that way we get the variable by itself.

x = 30

also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.

Step-by-step explanation:

3x+X+60=180

4x=180-60

X=120/4

X=30

Answer:   y=-2x+9

Step-by-step: Subtract 2x from 2x+y=9 and get y=-2x+9

Given:

[tex](x+9)^2[/tex]

To find:

The given expression as a trinomial in standard form.

Solution:

We have,

[tex](x+9)^2[/tex]

Using the formula, [tex](a+b)^2=a^2+2ab+b^2[/tex], we get

[tex](x+9)^2=x^2+2(x)(9)+(9)^2[/tex]

[tex](x+9)^2=x^2+18x+81[/tex]

Standard form a trinomial is [tex]ax^2+bx+c[/tex].

[tex]x^2+18x+81[/tex] is in the standard form.

Therefore, the required expression is [tex]x^2+18x+81[/tex].

Step-by-step explanation:

To find the slope of a line, you need to find the [tex]\frac{rise}{run}[/tex] between two points. I will be using the points (-3, 2) and (-1, -2).

[tex]\frac{rise}{run}[/tex] = [tex]\frac{-2-2}{-1-(-3)}[/tex]

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
