The difference of the squares of two positive consecutive even integers is 44 find the integers use the fact that if X represents an even integer then X +2 represents the next consecutive even integers
Answer:
The 2 integers are 10 and 12
Step-by-step explanation:
Translate it into english
"The difference (some subtraction) of the squares of two positive consecutive integers ([tex]x^2[/tex] and [tex](x+2)^2[/tex]) is (=) 44 (44)"
this means the following:
[tex](x+2)^2-x^2=44[/tex]
solve for x to find the smaller integer
first, expand
[tex](x^2+4x+4)-x^2=44[/tex]
[tex]x^2+4x+4-x^2=44[/tex]
[tex]4x+4=44[/tex]
[tex]4x=40[/tex]
[tex]x=10\rightarrow x+2=10+2=12[/tex]
The 2 integers are 10 and 12
whats the product of 0.02 x0.3?PLEASE ANSWER WITH STEPS PLEASEEEE,ITS URGENT
Answer:
0.006
Step-by-step explanation:
This is the answer because:
Short Way:
1) We know 3 x 2 is 6
2) When we multiply with zeros, how many ever zeros there are in the factors together, should be in the answer. In this case, in the answer we should have 3 zeros, one before the decimal point and two after the decimal point, because in 0.02 there are two zeros while in 0.3 there is only one zero.
3) Finally, the answer would be 0.006
Long Way:
1) You can do long multiplication to solve for the answer.
2) 0.02
× 0.3
Is 0.006 because 3 x 2 is 6, and then 3 x 0 is 0 and then 3 x 0 is 0.
006
+0000
0.006
Remember to put a decimal point.

A basketball player completed 44.2% of his field goals in the most recent season. He made 287 field goals. How many did he attempt?
44.2%= 287
Let the total attempt = x
(287/x) ×100 = 44.2
287/x = 44.2/100
287/x = 0.442
x = 287/0.442
x= 649Hope this will help...
Peyton received a $5,000 bonus at work, and plans to invest it today. Her investment account will earn a 5% interest rate, compounded monthly. What will her account value be in 20 years? Peyton will have $___ in the account after 20 years.
Answer:
$ 13,563.20
Step-by-step explanation:
Formula for total amount accrued or gathered after interest is compounded monthly = A = P(1 + r/n)^nt
A = Amount after t years
P = Initial amount Invested = $5,000
r = Interest rate = 5% = 0.05
n = compounding frequency = Every month = 12
t = time in years = 20
A = $5000(1 + 0.05/12)^20 × 12
A = $ 13,563.20
Therefore, Peyton will have $13,563.20 in the account after 20 years.
Answer:
FV = PV (1 + )nt
PV = $5,000
r = 0.05
n = 12
t = 20
FV = 5,000 (1 + )12 · 20
= 13,563

Three messenger services deliver to a small town in Oregon. Service A has 60% of all the scheduled deliveries, service B has 30%, and service C has the remaining 10%. Their on-time rates are 80%, 60%, and 40% respectively. a. What proportion of the packages in the town are delivered on time
Answer:
Proportion of total delivered on time is 70% or 7/10
Step-by-step explanation:
Here, we want to know the proportion of all the packages delivered on time.
Moving away from the percentage, let’s say the total produced package amongst the 3 is 100
So;
Service A has 60% which is 60
Service B has 30% which is 30
Service C has 10% which is 10
Now from here, we move as follows;
on time rate for service A is 80%
This means 80/100 of the 60 is delivered on time
That will be 80/100 * 60 = 48
For service B, 60% is delivered on time; Thus we have ;
60/100 * 30 = 1800/100 = 18
For service C , 40% of 10
40/100 * 10 = 4
So the total on time delivery will be;
18 + 4+ 48 = 70
So the proportion delivered on time will be 70/100 = 7/10 or 70%
A standard number cube is rolled. Calculate: P(rolling 1 or 3)
Answer:
the probability is:
P(A) 2/6 =1/3
Now let's take rolling a prime number:
A prime number is a natural number greater than 1 which can only be divided without a remainder by 1 and itself. So from the numbers on the cube prime numbers are:
2, 3 and 5. The probability of getting a prime number in a single roll is:
P(B) =3/6=1/2
Now to calculate the probability of A and B
you have to multiply both probabilities:
P(A-B)=P(A) . P(B) = 1/3 . 1/2 = 1/6

If a club charges dues of $200 a year, it will have 50 members. For each $5 it raises its dues, it loses a member. USE AN EQUATION to determine what the club should charge to maximize its income from dues.
Answer:
The value is [tex]y = \$ 225[/tex]
Step-by-step explanation:
From the question we are told that
The amount charge per year is [tex]k = \$ 200[/tex]
The number of members it will have at this amount is [tex]n = 50[/tex]
The amount amount increase that will lead to the loss of a single member is [tex]z = \$ 5[/tex]
Generally the total amount the club would obtain from its members is mathematically represented as
[tex]I = Amount \ due\ paid * Number \ of members[/tex]
Now let x denote the number of member lost
Hence
[tex]I = (k + zx) (n-x )[/tex]
=> [tex]I = (200 + 5x) (50-x )[/tex]
=> [tex]I = 10000+50x-5x^2[/tex]
Thus the number of members that be removed to give the maximum income from dues is obtained by differentiating the above equation and equating it to zero
[tex]\frac{dI}{dx} = 50-10x[/tex]
=> [tex] x = 5[/tex]
So from [tex]I = (200 + 5x) (50-x )[/tex] we have
[tex]I = (200 + 5 (5)) (50-5 )[/tex]
[tex]I = \$ 10125 [/tex]
So the amount the club should charge is
[tex]y = \frac{10125}{50 - 5}[/tex]
[tex]y = \$ 225[/tex]
A question asks: How many hours per week do you watch television? The respondent can answer in minutes and/or hours. What would be the best numerical summary of data from 300 participants? A. Mean, standard deviation, and range B. Median, IQR, and range C. Number and percent of total for each response option D. A or B depending on the distribution of the sample E. B and C
Answer: D. A or B depending on the distribution of the sample
Step-by-step explanation:
Given: A question ask about how many hours per week do you watch television?
Total participants = 300
Since all participants are different , so have their own answer to this question in numerical terms.
We use proportion or percentage to summarize data if data is categorical, but here data is numerical (continuous).
here , we can use either mean or median ( if it has outliers).
For this we need to check the distribution of the data, if it is normal then Mean, standard deviation, and range would be a better option (as mean is the best measure of tendency)otherwise Median, IQR, and range would be a better option .
hence, the correct option is D. A or B depending on the distribution of the sample

7. Cho Sasaki demonstrates microwave ovens at the National Home Show. She is
paid $7 each for the first 7 demonstrations and $11 for each demonstration over 7.
What is her commission for a day in which she makes 12 demonstrations
Answer:
The commission made is $104
Step-by-step explanation:
Here, given the payment analysis, we want to know the total pay for a day in which 12 demonstrations were made.
From the question, we can deduce the following;
For the first 7 demonstrations , $7 is paid
Now for the remaining 5 out of the total 12, the amount paid per demonstration is $11
So the total commission earned will be;
$7(7) + $11(5)
= $49 + $55 = $104
