Right tailed test

Step-by-step explanation:

The null hypothesis is:

[tex]H_o: \mu \le 30[/tex]

The alternative hypothesis is:

[tex]H_a: \mu > 30[/tex]

This is a right-tailed test since the alternative hypothesis is greater than 30

Suppose the level of significance is 0.05 and we are given a p-value less than  0.05.

Then, we reject the null hypothesis.

Step-by-step explanation:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\(-4,2)\quad\implies\quad x_1=-4\,,\ y_1=2\\\\(2,-6)\quad\implies\quad x_2=2\,,\ y_2=-6\\\\d=\sqrt{(2+4)^2+(-6-2)^2}= \sqrt{6^2+(-8)^2}= \sqrt{26+64}= \sqrt{100}=10[/tex]

Step-by-step explanation:

Line equation represents a line that passes through the two points  is

x-3=0

Given two points are (3,6) and (3,5)

Let say A=(3,6) and B=(3,5)

Formula for find out line equation using two points.

              [tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]

Slope can be denoted by m.

Slope formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

                         [tex]m=\frac{5-6}{3-3}[/tex]

                         m=-1/0

Line equation can be rewritten as  [tex]y-y_1=m (x-x_1)[/tex]

Submit m in above equation  

             [tex]y-6=\frac{-1}{0} (x-3)[/tex]

Simplify it.

             (y-6)*0=-1(x-3)    

                   x-3=0    

Therefore , line equation represents a line that passes through the two points  is x-3=0

Answer:

Step-by-step explanation:

A. Function before discount:

f(c)= 8.97c

This means that cost per strand of outdoor light is $8.97 and c is number of strands of outdoor light bought. Therefore to model the function g(c) after he has received a $5 discount on his purchase(total purchase)

g(c)=8.97c-5

B. cost of 6 strands of light before discount

f(c)= 8.97×6= $53.82

cost of 6 strands of light after discount

f(c)=8.97×6-5= $48.82

Step-by-step explanation:

x² + 12x - 40 = 0

x² + 12x    = 40

Now, 12/2 = 6. So add 6² = 36 to each side

x² + 12x + 36 = 40 +36

Answer: 18 quarts

Step-by-step explanation:

As per given,

Quantity of sparkling juice is proportional to quantity of course with grape juice.

Given: A free cable sparkling juice calls for [tex]1\dfrac12[/tex] quarters of sparkling water and [tex]\dfrac34[/tex] course with grape juice .

Let x be the quantity of sparkling water need to mix with 9 quarts of grape juice.

then, by equation of direct proportion , we have

[tex]\dfrac{1\dfrac12}{\dfrac34}=\dfrac{x}{9}\\\\\Rightarrow\dfrac{\dfrac{3}{2}}{\dfrac{3}{4}}=\dfrac{x}{9}\\\\\Rightarrow\ \dfrac21=\dfrac{x}{9}\\\\\Rightarrow\ x=9\times2\\\\\Rightarrow\ x=18[/tex]

Hence, the quantity of sparkling water need to mix with 9 quarts of grape juice = 18 quarts

Answer:

B

Step-by-step explanation:

Because 4 times 3.5 equals 14 and minus 3 equals -11 so its B.

Answer:

Your answer is B.

Step-by-step explanation:

The reason is because:

3-4x=-11

turns to

-4x=-14

when you subtract 3 from both sides then divide both sides by negative 4

and you get:

x=-14/-4

if you simplify -14/-4 your final answer will be

7/2 which equals 3.5:    x=3.5

Answer:

Step-by-step explanation:

The midpoint of the line segment is (2,5) (option B)

When given the end points of a line segment, you can find out its midpoint by using the midpoint formula. As the name might have already suggested, midpoint is basically the halfway between two end points. All you need to do is dividing the sum of x-values and the sum of y-values by 2.

The sum of x coordinate is -1+5 = 4

half of sum of x coordinate = 4/2 = 2

The sum of y coordinate = 5+5= 10

half of sum of y coordinate = 10/2 = 5

therefore the midpoint of the line is ( 2,5)

Answer:

AB = 20 units

Step-by-step explanation:

Given the coordinate midpoint M(4.-2) and A(-2,6), we are to find the length AB. To get that, we need to get the coordinate of B first as shown

M(X, Y) = [(x1+x2/2, y1+y2/2]

X = x1+x2/2

4 = -2+x2/2

8 = -2+x2

x2 = 8+2

x2 = 10

Y = y1+y2/2

-2 = 6+y2/2

-4 = 6+y2

y2 = -4-6

y2 = -10

Hence the coordinate of B is (10, -10)

Recall that A =(-2, 6)

Get AB;

AB = √(x2-x1)²+(y2-y1)²

AB = √(-2-10)²+(6+10)²

AB = √(-12)²+(16)²

AB = √144+256

AB = √400

AB = 20 units
