What is the image point of (-9,6) after a translation left 4 units and down 4 units
Answer:( -13,2)
Step-by-step explanation:
In 2018, homes in East Baton Rouge (EBR) Parish sold for an average of $239,000. You take a random sample of homes in Ascension parish and find that the average home sale price was $246,000 in 2018. You test the hypothesis that the mean of the home prices from Ascension parish is higher than the EBR mean. Suppose the p-value for the test is 0.045. At the 0.10 level of significance your conclusion is:_______
A. There is evidence that the average home price of homes sold in Ascension parish in 2018 is higher than the average price of homes sold in EBR parish.
B. There is no evidence that the average home price of homes sold in Ascension parish in 2018 is higher than the average price of homes sold in EBR parish.
C. There is not enough information for decision-making.
Answer:
Option B: There is no evidence that the average home price of homes sold in Ascension parish in 2018 is higher than the average price of homes sold in EBR parish
Step-by-step explanation:
We are given;
Population mean of EBR Parish; μ1 = $239,000
Sample mean of Ascension parish; x2 = $246,000
P-value = 0.045
Population mean of Ascension parish; μ1 =?
Now,let's define the hypothesis;
Null Hypothesis; H0: μ2 = μ1
Alternative hypothesis; Ha: μ2 > μ1
Now, we are told that the level of significance is 0.1.
Thus; α = 0.1
Now,the level of significance of 0.1 is greater than the p-value which is 0.045 and thus we will fail to reject the null hypothesis and conclude that there is not enough evidence to conclude that the average home prices in Ascension parish in 2018 is higher than the average price of homes sold in EBR parish.

Let g(x) = 2x and h(x) = x2 + 4. Evaluate (h ∘ g)(−2)
Answer:
[tex](h(g))(-2)=-32[/tex]
Step-by-step explanation:
Evaluate h ⋅ g
Replace the function designators in h ⋅ g with the actual functions.
[tex](h(g))(-2)=(x^{2} +4)(2x)[/tex]
[tex]=2x^{2}x+8x[/tex]
Multiply [tex]x^{2}[/tex] by x by adding the exponents.
[tex]=2x^{3}+8x[/tex]
Evaluate h ⋅ g at −2.
[tex]=2(-2)^{3}+8(-2)[/tex]
Simplify
[tex]=-16-16[/tex]
subtract 16 from -16
[tex](h(g))(-2)=-32[/tex]

tan∧2 3Ѳ = 3, Ѳ is acute, then Ѳ is = PLEASE ANSWER FAST
Answer:
20
Step-by-step explanation:
We are given:
Tan²3Θ = 3
taking the square root of both the sides
Tan 3Θ = √3
3Θ = Arctan(√3)
the Arctan function takes a value as an input and outputs the angle at which you will have tanΘ = the input value
3Θ = 60
Θ = 20°
a graphic designer wants to know the number of regions that are formed when circles overlap in particular. can she find a rule that describes how the number of regions increases when another circle is added to the design? how many regions would a design with 6 circles create?
Answer:
A. 2
Step-by-step explanation:
Its successive multiples and it increases:
+2, +4, +6, +8
it increases by 2 every time which is successive multiples so the answer is A, 2.
Identifying the pattern, it is found that the correct option is:
A. As the number of circles increases, the number of regions increases by successive multiples of 2 each time.
With 6 circles, there are going to be 31 regions.------------------------
With 1 circle, there is 1 region.With 2 circles, there are 3 regions. Thus, it increased by 2.With 3 circles, there are 7 regions. The increase was of 7 - 3 = 4.With 4 circles, there are 13 regions. The increase was of 13 - 7 = 6.With 5 circles, there are 21 regions. The increase was of 21 - 13 = 8.(2,4,6,8) are consecutive multiples of 2, thus, the correct option is:
A. As the number of circles increases, the number of regions increases by successive multiples of 2 each time.
------------------------
The next multiple of 2 is 10.Thus, with 6 circles, there will be 21 + 10 = 31 regions.A similar problem is given at https://brainly.com/question/23061765
Given g(x) = -x + 3, solve for x when g(x) = -1.
Answer:
4
Step-by-step explanation:
It's ok! This is simple. Simply plug in your given values. Since g(x) = -1, plug that into the equation.
g(x) = -x + 3
g(-1) = -(-1) + 3
=1+3
=4
Answer:
- x + 3 = - 1 ⇒ x = 4

The computers of six faculty members in a certain department are to be re- placed. two of the faculty members have selected laptop machines and the other four have chosen desktop machines. suppose that only two of the se- tups can be done on a particular day, and the two computers to be set up are randomly selected from the six (implying 15 equally likely outcomes; if the com- puters are numbered 1,2,...,6, then one outcome consists of computers 1 and 2, another consists of computers 1 and 3, and so on).
(a) what is the probability that both selected setups are for laptop computers?
(b) what is the probability that both selected setups are desktop machines?
(c) what is the probability that at least one selected setup is for a desktop computer?
(d) what is the probability that at least on computer of each type is chosen for setup?
Answer:
A) The probability that both selected setups are for laptop computers is 0.067
B)The probability that both selected setups are desktop machines is 0.4
C)The probability that at least one selected setup is for a desktop computer is 0.933
D)The probability that at least on computer of each type is chosen for setup is 0.533
Step-by-step explanation:
Number of laptops = 2
Number of desktops = 4
Total number of outcomes = 15
a) what is the probability that both selected setups are for laptop computers?
Total number of outcomes = 15
So, the probability that both selected setups are for laptop computers = [tex]\frac{1}{15}=0.067[/tex]
b)what is the probability that both selected setups are desktop machines?
Number of desktops = 4
Number of desktops to be chosen = 4
We will use combination
No. of ways to select two desktops =[tex]^4C_2=\frac{4!}{2!(4-2)!}=6[/tex]
So,the probability that both selected setups are desktop machines=[tex]\frac{6}{15}=0.4[/tex]
(c) what is the probability that at least one selected setup is for a desktop computer?
P(at least 1 desktop)=1-P(No desktop)
P(at least 1 desktop)=1-P(both laptops)
P(at least 1 desktop)=1-0.067=0.933
So,the probability that at least one selected setup is for a desktop computer is 0.933
d) what is the probability that at least on computer of each type is chosen for setup?
No. of ways to select one desktop [tex]=^4C_1=\frac{4!}{1!(4-1)!}=4[/tex]
No. of ways to select one laptop =[tex]^2C_1=\frac{2!}{1!(2-1)!}=2[/tex]
So, No. of ways to select one laptop and one desktop= [tex]4 \times 2 = 8[/tex]
So,the probability that at least on computer of each type is chosen for setup=[tex]\frac{8}{15}=0.533[/tex]

What is the combined weight of all the baskets that weigh exactly
Answer:
All baskets combined weight is 9 pounds.
Step-by-step explanation:
Total weight of berries 5 / 4
Weight of first basket 2 pounds
Weight of second basket 3 pounds
Weight of third basket 4 pounds
Weight of forth basket 5 pounds
Weight of first basket with berries is
2 - [tex]\frac{5}{4}[/tex] = [tex]\frac{3}{4}[/tex] pounds
Weight of second basket with berries is 7 / 4
Weight of third basket with berries is 11 / 4
Weight of forth basket with berries is 15 / 4
Total weight of all baskets is
[tex]\frac{5}{4} + \frac{7}{4} + \frac{11}{4} + \frac{15}{4}[/tex] = 9 pounds.
