Answer:
1. a. z test for means and t test for means.
2. C. HA : mu1 - mu2 > 0
Step-by-step explanation:
Hypothesis testing is used in a situation where there are more than 1 alternative available. The t test is conducted in the mean which determines the t value and then this value is compared with p value to identify the situation whether to accept or reject the null hypothesis. The alternative hypothesis in this situation is is represented by mu.

a man gets $312 for working 48 hours a week. how much does he get when he works 36 hours a week?
Answer:
$234
Step-by-step explanation:
Create a proportion where x is the amount he gets working 36 hours
[tex]\frac{312}{48}[/tex] = [tex]\frac{x}{36}[/tex]
Cross multiply and solve for x
48x = 11232
x = 234
So, when he works 36 hours a week, he will get paid $234
Answer:
assuming he is paid hourly?
312÷48= 6.50/hour
so, 6.50÷36= $234

Step-by-step explanation:
Anna sold 1 tie for every 4 shirts. Which proportion would determine how many shirts she would need to sell along with 16 ties?
Answer:
64 shirts
Step-by-step explanation:
The ratio of ties to shirts is 1:4, so if the number of ties was 16, then you would have to multiply 16(number of ties) by 4(number of shirts), 16 x 4=64. therefore the awnser will be 64 shirts. Your welcome
Determine whether the underlined number is a statistic or a parameter. Choose the correct statement below. because the value is a numerical measurement describing a characteristic of a . because the value is a numerical measurement describing a characteristic of a . because the value is a numerical measurement describing a characteristic of a . because the value is a numerical measurement describing a characteristic of a .
Complete question :
Determine whether the underlined number is a statistic or a parameter.
"In a study of all 4841 students at a college, it is found that 55% own a computer."
Answer:
because the value is a numerical measurement describing a characteristic of a population.
Step-by-step explanation:
The difference between statistic and parameter lies in the fact that, statistics are used in describing the numerical value obtained from a sample of data. While parameter are used to describe the numerical characteristics of a population.
Hence, all students of a college refers to the population(entire students). Therefore, the numerical characteristics obtained from such data would be called a parameter.
Christopher works as a translator of
literature. He gets paid different
amounts for translating articles and for
translating book chapters. In January,
he was paid $340 for translating 3 book
chapters and 2 articles. In February,
he was paid $380 for translating 1 book
chapter and 6 articles. How much is
Christopher paid, in dollars, to translate
each article?
Answer:
50$
Each book is equal to 80 now here's the math
50x2=100 340-100=240/3=80
380-80=300/6=50

Point J is located at (-2, -5) and Point K is located 5 units right and 9 units up Which measurement is closest to the distance between Point J and Point K?
A. 3.7 units
B. 7.5 units
C. 10.3 units
D. 12 units
Answer:
Step-by-step explanation:
d^2=(x2-x1)^2+(y2-y1)^2
Here we are told dx=5 and dy=9 so
d^2=25+81
d^2=106
d=10.3 units
This value is approximate. This also means that segment JK is roughly 10.3 units.
==============================================================
Explanation:
The "5 units right and 9 units up" means we have a right triangle with legs 5 and 9. The hypotenuse is unknown, which I'll call c.
a = 5b = 9c = unknownApply the pythagorean theorem. Solve for c.
a^2 + b^2 = c^2
5^2 + 9^2 = c^2
25 + 81 = c^2
106 = c^2
c^2 = 106
c = sqrt(106)
c = 10.2956301 approximately
c = 10.3 approximately
The distance from J to K is roughly 10.3 units
------------------------------------
A slightly different method:
Start at point J (-2, -5) and move 5 units to the right and 9 units up to arrive at K(3, 4)
Let's use the distance formula to find the distance from (-2,-5) to (3,4)
Define the following
(x1,y1) = (-2,-5) which means x1 = -2 and y1 = -5(x2,y2) = (3,4) which means x2 = 3 and y2 = 4Those values are then plugged into the distance formula
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-2-3)^2 + (-5-4)^2}\\\\d = \sqrt{(-5)^2 + (-9)^2}\\\\d = \sqrt{25 + 81}\\\\d = \sqrt{106}\\\\d \approx 10.2956301\\\\d \approx 10.3\\\\[/tex]
The distance from J to K is roughly 10.3 units
One thing to point out, as you probably already noticed, is that the distance formula and pythagorean theorem effectively are saying the same thing when computing distances like this. The distance formula is based off the pythagorean theorem. Note the x1-x2 portion which represents the horizontal distance from J to K. This is the "move 5 units right" portion. Then the "y1-y2" is the vertical change in distance, which is the "move 9 units up". Also, we can see that the square root of 106 shows up again; a lot of elements are repeated (just phrased in a slightly different way) from the last section.
simplify the above expression, then tell me what rule you used, (product rule, power rule, quotient rule.) then explain how you did the problem
Answer:
Step-by-step explanation:
You have to use the power rule for this. The way I teach my Algebra 1 students to do this is take everything inside the parenthesis and put it into its own set of parenthesis, and then raise each one to the outside power. One thing at a time makes it not so overwhelming. Like this:
[tex](4)^2(x^5)^2(y^3)^2[/tex]
Now follow the power rule. Multiply the power of each element in the parenthesis by the 2 outside.
[tex](4^1)^2=4^2=16[/tex], then [tex](x^5)^2=x^{10[/tex], and finally, [tex](y^3)^2=y^6[/tex].
Now put it all together to get:
[tex]16x^{10}y^6[/tex]

Answer:
1/4, 3/5, 8/10
Step-by-step explanation:
3/5 is greater than 1/4
(2/4 is equal to 2.5/5---that should give you a visual picture why)
8/10 is greater than 3/5
3/5 multipled by 2 is 6/10
so, 6/10<8/10

The area of a square screen is 100 cm². Find the side length
of the screen.
Answer:
10 cm
Step-by-step explanation:
From the question,
Area of a square = (Length)²
A = L²............................ Equation 1
Where A = Area of the screen, L = Length of the Screen
make L the subject of the equation
L = [tex]\sqrt{A}[/tex].................... Equation 2
Given: A = 100 cm²
Substitute into equation 2
L = [tex]\sqrt{100}[/tex]
L = 10 cm
Hence the length of the screen is 10 cm
Find the measure of angle w
Answer: Angle w=90
Step-by-step explanation: A line is 180 degress,so 90 plus w = 180. 180-90 is 90, so w is 90.
Answer:
90
Step-by-step explanation:
There is perpendicular bisector separating a given angle of 90, and a variable of w
We can assume the other ray is at a 180 degree angle, this means we can find w by using this simple equation; 180 - (given number) = remaining number, in this case, w.

Jessie bought 12 cases of soda for the party. If his total bill was $41.40, how much did each case cost?
Answer:
B. $3.45
Step-by-step explanation:
Number of cases of soda bought = 12
Total bill payed = $41.40
Let x represent the cost of 1 case.
Thus:
12x = $41.40
Divide both sides by 12
12x/12 = 41.40/12
x = 3.45
Cost of each case = x = $3.45
