Answer:
a. yes there is enough evidence
B. -22.83, 102.79
Step-by-step explanation:
H0: B2 >= 0
H1: B2 < 0
Alpha = 0.05
T critical is calculated to be -1.79
If t is less than -1.79 we reject the null hypothesis
Test statistic
S = √1107.01/15-3-1
= 10.032
T stat = -0.92 - 0/10.032√0.00081
= -3.222
-3.222 is less than -1.79
So we Reject the null hypothesis and conclude that enough evidence exists that B2<0
B. At 95% confidence
38.83 - 0.0092x1 - 0.92x2 + 11.56x3
= 38.83 - 0.0092x914 - 0.92x65 + 11.56x6
= 38.83 - 8.4088 - 59.8 + 69.36
= 39.98
39.98-2.2*28.55,39.85+2.2*28.55
= 39.98 - 62.81, 39.98 + 62.81
= -22.83, 102.79

Answer:
[tex]After\ Tax = 7490[/tex]

Given
[tex]Days = 2[/tex]
[tex]Rent = 3500[/tex] daily
[tex]Tax = 7\%[/tex]

1. A rectangular room measures 12 feet by 20 feet. It is going to be covered with carpeting that sells for $8.35 per square foot.
a. What is the area of the room in square feet?
b. How much would it cost to carpet the floor?
Answer:
a). 240sqft b). $2004 (+ labor I guess)
Step-by-step explanation:
the room is rectangular, so it's area is the product of the dimensions
12feet * 20feet = 240sqft
The cost is $8.35 per sqft, so we get
240sqft * $8.35/sqft = $2004
Answer:
A: 240
B: 1,980
Step-by-step explanation:

Answer:
WZX = 41 degrees
Step-by-step explanation:
XYZ is congruent/equal to XWZ, which is 68 degrees
180 degrees in a triangle so let's use WXZ as one
180 - 68 = 112
then the next angle is WXZ, which is also in the triangle so
112 - 71
which equals 41

Answer:
A prediction based on the data is reliable, because the means of the samples are close together.
Step-by-step explanation:
Test approved
The most accurate statement is A. A prediction based on the data is reliable, because the means of the samples are close together.
What is Mean?Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.
Given three data sets.
All the samples have 10 data points.
Number of data points = 10
Mean of sample 1 = 9.1
Mean of sample 2 = 9.4
Mean of sample 3 = 8.9
We can see that the mean of the three samples is so close to each other.
So the data is reliable.
Hence the option is A.

What is the greater faction than 11/20
Answer:
Are you looking to calculate whether 2/10 is greater than 11/20? One of the most common calculations you'll make in math is to compare fractions. In this really simple guide, we'll teach you how to compare and determine if 2/10 is bigger than 11/20 and walk you through the step-by-process of how the calculation is made.
As we always do in these tutorials, let's recap and remind ourselves that the number above the fraction line is called the numerator and the number below the fraction line is called the denominator.
Depending on the math problem you want to solve, there are two methods to calculate if 2/10 is larger than 11/20:
Convert the fractions to have the same denominator
Convert the fractions to a decimal number
Let's start with the first method: converting the fractions to the same denominator. First, we'll set up 2/10 and 11/20 side by side so they are easier to see:
Converting Denominator
2
10
&
11
20
Our denominators are 10 and 20. What we need to do is find the lowest common denominator of the two numbers. This is the smallest number that can be divided by both 10 and 20. In this case, the lowest common denominator is 20.
If we multiply the first denominator (10) by 2 we will get 20. If we multiply the second denominator (20) by 1 we will also get 20. We also need to multiply the numerators above the line by the same amounts so that the fraction values are correct:
2 x 2
10 x 2
11 x 1
20 x 1
This is what 2/10 and 11/20 looks like with the same denominator:
4
20
&
11
20
Now that these fractions have been converted to have the same denominator, we can clearly see by looking at the numerators that 4 is NOT greater than 11 which also means that 2/10 is NOT greater than 11/20.
Converting to Decimal
You can also compare these fractions by first converting them to decimal format. This is a lot faster than working out the lowest common denominator. All we do here is divide the numerator by the denominator for each fraction:
2/10 = 0.2
11/20 = 0.55
Now that these fractions have been converted to decimal format, we can compare the numbers to get our answer. 0.2 is NOT greater than 0.55 which also means that 2/10 is NOT greater than 11/20.
Hopefully this tutorial has helped you to understand how to compare fractions and you can use your new found skills to compare whether one fraction is greater than another or not!
