Substitute x = 2 as we get
f(2) = -4(2)+4 = -8+4 = -4
Therefore, f(2) = -4
The Fenwick family filled their new in-ground swimming pool with 75,700 liters of water. One gallon of water is about 3.785 liters. About how many gallons of water are in the pool? How much gallons? You get 30 points to answer this.
Answer:20000
Step-by-step explanation:
Working together, two pumps can drain a certain pool in 3 hours. If it takes the older pump 12 hours to drain the pool by
itself, how long will it take the newer pump to drain the pool on its own?
Do not do any rounding.
The more recent pump can clean the pool itself in 4 hours, as per the question we have.
What are a pump and a type?Pumps are primarily classified into two broad categories: 1. Kinetic and dynamic pumps. Fluid passing by or through the impeller of a dynamic pump is given velocity and pressure.
Let's refer to the earlier pump's rate as "p1" and the more recent pump's rate as "p2."
The older pump took 12 hours to drain the swimming pool on its own.
Together, the two pumps' operating time equals 3 p1, or 1/12 of the pool's volume each hour.
And if the pool can be drained by the two pumps over 3 hours, so p1 + p2 equals one-third of a water's volume each hour.
We can solve for p2:
p2 = (1/3) - p1
p2 = (1/3) - (1/12)
p2 = 1/4 of the pool's volume per hour.
So the newer pump can drain the pool by itself in 4 hours.

What is thirty five thousandths as decimal numerals
Answer: Thirty five thousandths as decimal numerals is 0.035
The value of thirty five thousandths as decimal numerals is 0.035.
We are given that;
Decimal numerals =Thirty five thousandths
Now,
One thousandth is equal to 0.001,
so thirty five thousandths is equal to 0.001 x 35 = 0.03512.
Also, it is moving the decimal point three places to the left of 35, since there are three zeros in 1000
Therefore, by decimal the answer will be 0.035.

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.
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

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]
