Answer:
no, I believe the correct answer would be D. (-4, 4)
Answer:
(-4, 4)
Step-by-step explanation:
Even though I don't see it explained anywhere, it seems that what looks like the coordinates of two points is really the coordinates of the first point and the translation.
That means that (-9, 6) is the original point.
(5, -2) is the translation which is a translation of 5 in x and a translation of -2 in y.
Start with (-9, 6)
Apply the translation to x and y (-9 + 5, 6 + (-2))
You get (-4, 4)
Answer: (-4, 4)

The area of a rectangular wall of a barn is 144 square feet. Its length is 10 feet longer than the width. Find the length and width of the wall of the barn.
The width is __feet.
Answers
Answer:
8 feet
Step-by-step explanation:
Let l and w be length and width, respectively. Then:
lw=144 and
l=w+10
So:
w(w+10)=144
w²+10w-144=0
(w+18)(w-8)=0
w=8 as the width ................
The width of the rectangular wall is 8 feet.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.
Let l and w be length and width, respectively. Then:
l x w=144
l = w + 10
The area will be given as;-
w(w+10)=144
w²+10w-144=0
(w+18)(w-8)=0
w = 8 and -18 ignore -18.
Therefore the width of the rectangular wall is 8 feet.

Step-by-step explanation:
Given
The attached table
Required
Determine his percentage commission
To do this, we need to calculate the slope (m) of the table as follows:
[tex]m = \frac{P_2 - P_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,P_1) = (7000,165)[/tex]
[tex](x_2,P_2) = (7500,172.5)[/tex]
[tex]m = \frac{P_2 - P_1}{x_2 - x_1}[/tex] becomes
[tex]m = \frac{172.5 - 165}{7500- 7000}[/tex]
[tex]m = \frac{7.5}{500}[/tex]
[tex]m = 0.015[/tex]
Convert to percentage
[tex]m = 0.015 * 100\%[/tex]
[tex]m = 1.5\%[/tex]
Hence, his percentage commission is 1.5%

Suppose we wish to demonstrate that there is a difference between the proportions of wives and husbands who do laundry at home. From a random sample of 66 randomly selected wives, we observe 44 who do laundry at home. From a random sample of 46 husbands, we observe 18 who do laundry at home. Test the claim that the proportion of wives, p 1 , who do laundry at home is different from the proportion of husbands, p 2 , who do laundry at home. Use a 1% significance level.
Answers
Answer:
Step-by-step explanation:
From this study:
The null hypothesis:
[tex]H_o : p_1 =p_2[/tex]
The altenative is:
[tex]H_a : p_1 \ne p_2[/tex]
This test is a two-tailed test.
However; we are told that the wives have 44 success out of 66, then the number of failures will be 22.
Then;
[tex]\hat p_1 = \dfrac{44}{66}[/tex]
[tex]\hat p_1 = 0.6667[/tex]
Similarly, the husbands have 18 success out of 46, then the number of failures will be 28
Then:
[tex]\hat p_2 = \dfrac{18}{46}[/tex]
[tex]\hat p_2 = 0.3913[/tex]
The pooled proportion [tex]p = \dfrac{18+44}{66+46}[/tex]
[tex]p = \dfrac{62}{112}[/tex]
p = 0.55357
The estimated standard error S.E is:
[tex]= \sqrt{\dfrac{ \bar p(1- \bar p)}{n_1} +\dfrac{ \bar p(1-\bar p)}{n_2}}[/tex]
= [tex]\sqrt{ 0.55357(1-0.55357) \Big( \dfrac{1}{66} + \dfrac{1}{46} \Big)}[/tex]
[tex]=\sqrt{ 0.55357(0.44643) \Big(0.01515 + 0.021739 \Big)}[/tex]
[tex]=\sqrt{ 0.00911638798}[/tex]
= 0.0955
The Z test statitics can now be computed as:
[tex]Z = \dfrac{ \hat p_1 - \hat p_2}{\sqrt{\dfrac{ \bar p(1- \bar p)}{n_1} +\dfrac{ \bar p(1-\bar p)}{n_2}}}[/tex]
[tex]Z = \dfrac{0.6667 -0.3913}{0.0955}[/tex]
Z = 2.88
Th p -value from the test statistics is:
p-value = 2P(Z > 2.88)
p- value = 2 P (1 - Z < 2.88)
p-value = 2 ( 1 - 0.998)
p-value = 2 ( 0.002)
p -alue = 0.004
Decision Rule:
Thus, at 0.01 significance level, we reject the null hypothesis because, p-value is less than that (i.e. significance level)
Conclusion:
We conclude that there is a significant difference between the proportions.

Answer:
0.27

Step-by-step explanation:
Given that:
X :
L1 = 40% = 0.4
L2 = 30% = 0.3
L3 = 20% = 0.2
L4 = 30% = 0.3
P(x) :
L1 = 0.2
L2 = 0.1
L3 = 0.5
L4 = 0.2
A.)
Σ(X * p(x))
(0.4 * 0.2) + (0.3*0.1) + (0.2*0.5) + (0.3 * 0.2) = 0.27
B.) Radartrap located at L2:
P(L2) = (L(x2) * p(L2)) / Σ(X * p(x))
= (0.1 * 0.3) / 0.27
= 0.1111111
