The results that follow were obtained from an analysis of data obtained in a study to assess the relationship between percent increase in yield (Y) and base saturation (x1, pounds/acre), phosphate saturation (x2, BEC%), and soil pH (x3). Fifteen responses were analyzed in the study. The least-squares equation and other useful information follow.
y^=38.83-0.0092x1-0.92x2-11.56x3, Syy=10965.46, SSE=1107.01
a. Is there sufficient evidence that, with all independent variables in the model, β2 < 0? Test at the α = .05 level of significance.
b. Give a 95% confidence interval for the mean percent increase in yield if x1 = 914, x2 = 65 and x3 = 6.
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

Number of exemptions at $3650 each
Esther has 2
Frank has 2
Macy has 1
Penny has 3
Answer:
Frank
Step-by-step explanation:
The worker that had the lowest taxable income last year was Frank
What is Tax?This refers to the deductions that are made based on income and earnings where a certain percentage is remitted to the government.
Hence, we can see that based on the gross income and the standard deduction that was made between Esther, Frank, Macy, and Penny, and the exception of %$3,650, Frank had the lowest taxable income last year

A nap has a scale of 1cm to 16km on a map the distance between York and London is 23.1cm what is the real distance in km between York and London
Answer: 369.6km
Step-by-step explanation:
From the question, we are informed that a map has a scale of 1cm to 16km. We are further told that the distance between York and London is 23.1cm.
Therefore, the real distance in km between York and London will then be represented by x. Therefore,
1cm / 23.1cm = 16km / x
Cross multiply
1 × x = 23.1 × 16
x = 369.6km
The real distance in km between York and London is 369.6km
The temperature is -2c. If the temperature rises by 15c what is the new temperature?
Answer:
13c
Step-by-step explanation:
-2+15=13
13c
Answer:
13c
Step-by-step explanation:
To find the new temperature, add 15 to -2, since the temperature rose by 15c and was originally -2c.
-2 + 15
= 13
So, the new temperature will be 13c.
203% of what number is 146.16
Answer:
72
Step-by-step explanation:
Since 203% is 2.03 in decimal form we can write an equation that looks like:
2.03x=146.16 (divide both sides by 2.03)
x=72
Answer:
72
Step-by-step explanation:
Call the unknown number (x), set up a proportion to model the situation;
[tex]\frac{value}{unknown}=\frac{percent}{100}[/tex]
Substitute
[tex]\frac{146.16}{x}=\frac{203}{100}[/tex]
Cross products,
[tex](146.16)(100)=(203)(x)\\\\14616=203x\\[/tex]
Inverse operations,
[tex]14616=203x\\/203\\\\72 = x[/tex]

A triangle has vertices X(2, 1), Y(5, 4), and Z(5, 1). What is the area of the triangle?
Answer:
Step-by-step explanation:
They gave you an easy triangle. You can tell by the coordinates that X and Z are horizontally aligned, and Y and Z are vertically aligned, so Z is a right angle.
Area = 0.5(XZ)(YZ) = 0.5(3)(3) = 4.5 square units.
Maya earned $104,000 last year. If the first $40,000 is taxed at 12% and income above that is taxed at
18%, how much does Maya owe in tax?
Answer:
16,320
Step-by-step explanation:
There are $18,720 Maya owe in tax.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Maya earned $104,000 last year.
The first $40,000 is taxed at 12% and income above that is taxed at 18%.
Hence, Tax pay by Maya is,
⇒ 18% of 104,000
⇒ 18/100 × $104,000

160°
60°
50°
100°
Answer:
160°
Step-by-step explanation:
Quadrilateral's angles add up to 360 degrees.
So:
x = fourth angle measure (unknown currently)
50° + 72° + 78° + x = 360°
200° + x = 360°

Keiko, Dale, and Tony sent a total of 95 text messages during the weekend. Dale sent 7 fewer messages than Kelko. Tony sent 4 times as many messages as
Keiko. How many messages did they each send?
Answer:
Keiko sent 17 messages, Dale sent 10 messages, and Tony sent 68 messages
Step-by-step explanation:
Let x represent the number of messages that Keiko sent.
Since Dale sent 7 less than Keiko, his number can be represented by x - 7
Since Tony sent 4 times as many as Keiko, his number can be represented by 4x
Using these variables, create an equation:
(x) + (x - 7) + (4x) = 95
Add like terms and solve for x:
6x - 7 = 95
6x = 102
x = 17
So, Keiko sent 17 messages.
Subtract 7 from this to find how many Dale sent:
17 - 7
= 10
Multiply it by 4 to find how many Tony sent:
17(4)
= 68
So, Keiko sent 17 messages, Dale sent 10 messages, and Tony sent 68 messages

outline three methods of sampling
Answer: See explanation
Step-by-step explanation:
The sampling methods include:
1. Simple random sampling: Here, the individuals in the population have an equal chance of being selected as the selection is done randomly and anyone can be picked from the population
2. Systematic sampling: This is when the selection of the individuals is done at regular intervals. For example from the population, every 10th person might be picked.
3. Stratified sampling: Here, the total population is first divided into a smaller group called the strata before the sampling is done.
4. Clustered sampling: Here, the sampling unit is the subgroups of the population and not the individuals.

Answer:
672 m^3
Step-by-step explanation:
The formula to find the volume of a prism is V = l x w x h, where l is length, w is width, and h is height. You are given the length, width, and height in the problem so you just plug it into the formula.
V = 8 x 6 x 14
After multiplying all three numbers together, you should get the answer 672 m^3.

The triangle STU has been drawn on to a centimetre grid.
Calculate the area of triangle STU *
(2 Points)
Enter your answer
Answer:
12 square units
Step-by-step explanation:
The area of a given figure is the measure of space occupied by the figure on a 2 dimensional plane.
Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height
From the given grid, the following can be observed for triangle STU.
base SU = 6 units
height = 4 units
Thus,
area of triangle STU = [tex]\frac{1}{2}[/tex] x base x height
= [tex]\frac{1}{2}[/tex] x 6 x 4
= 3 x 4
area of triangle STU = 12 square units
The required area of triangle STU is 12 square units.

A. 5
B. -1
C. 1
D. 4
==============================================================
Work Shown:
I'm assuming you meant to write [tex]f(x) = 2^{x+4}[/tex] where all of the "x+4" is the exponent.
If we shift f(x) 5 units to the right to end up with g(x), then,
[tex]g(x) = f(x-5)\\\\g(x) = 2^{x-5+4}\\\\g(x) = 2^{x-1}\\\\[/tex]
In the second step, I replaced every copy of x with x-5 so that I could apply the translation of 5 units to the right.
The exponent for g(x) is x-1, which matches up with x-k. We see that k = 1.
