Blythe is 35 years old. She is planning on retiring in 30 years. She has opened an IRA with an APR of 1.75% compounded monthly. If she makes monthly
deposits of $650 to the account, how much will she have in the account when she is ready to retire?
$507,459.27
B) $107,659.27
$497,347.27
D) $307,459.27
The correct answer is A) $507,459.27. Blythe will have approximately $507,459.27 in her account when she is ready to retire.
To calculate the future value of Blythe's IRA, we can use the formula for compound interest:
A = P [tex]\times (1 + r/n)^{(nt)[/tex]
Where:
A is the future value
P is the monthly deposit amount ($650)
r is the annual interest rate (1.75% or 0.0175 as a decimal)
n is the number of times interest is compounded per year (monthly, so 12)
t is the number of years (30)
Substituting the given values into the formula:
A = 650 [tex]\times (1 + 0.0175/12)^{(12\times30)[/tex]
Calculating this expression yields A ≈ $507,459.27.
Therefore, the correct answer is A) $507,459.27. Blythe will have approximately $507,459.27 in her account when she is ready to retire.

Find the value of x and the value of y.
Answer:
x = 45
y = 20
Step-by-step explanation:
3y + 6y + 2x + 90 = 360 (Angles of a parallelogram ALWAYS add up to 360)
9y + 2x + 90 = 360 (Combine like terms) (2x = 90 because angles are congruent) {2x = 90; x = 45]
9y + 90 + 90 = 360 (Add like terms)
9y + 180 = 360 (Subtract 180 from both sides)
9y = 180 (Divide both sides)
y = 20
Setting 7 over 3 equal to which ratio would result in a valid proportion?
9 over 4
18 over 42
42 over 18
49 over 9
Answer:
42 over 18
Step-by-step explanation:
Notice that the quotient 42 over 18 can be written in factor form as:
(2 * 3 * 7) / (2 * 3 * 3) and therefore, a pair of "2" factors and a pair of "3" factors from numerator and denominator can be cancelled, leaving the ratio 7 / 3 which is the one we were discussing.
find two numbers whose product is 10 and whose sum is 7
Answer:
5 and 2
Step-by-step explanation:
5+2=7
5 times 2= 10
The two numbers whose product is 10 and whose sum is 7 are 5 and 2.
Let the two numbers required be x and y.
If the product of the two numbers is 10, then:
xy = 10 ...... 1
If the sum of the numbers is 7, then:
x + y = 7.... 2
Solve both equations simultaneously
From equation 2,
y = 7-x ... 3
Substitute equation 3 into 1 to have:
x(7-x) = 10
Expand
7x - x² = 10
Rearrange in standard form
x² - 7x + 10 = 0
Factorize
x² - 5x - 2x + 10 = 0
x(x-5)-2(x-5) = 0
(x -5)(x-2) =0
x - 5 = 0 and x - 2 = 0
x = 5 and 2
If x = 5:
y = 7 - 5
y = 2
Hence the two numbers whose product is 10 and whose sum is 7 are 5 and 2.

Suppose we are interested in surveying the problematic water pipes in New York City. It is known that 10% of the NYC water pipes have some problems. City officials develop a non-intrusive test machine to scan the underground pipes. The machine correctly identifies 95% of the problematic sites (i.e. the machine says the pipe has a problem for a site that in fact has an issue), but it wrongly identifies 5% of the sites as problematic (i.e. machine says the pipe has a problem for a site that does not have an issue with the probability of 5%). What is the probability that a site has no problem when the machine says that the pipe at the site has no issue
Answer:
The probability that a site has no problem when the machine says that the pipe at the site has no issue is
0.905
Step-by-step explanation:
Confidence level = 95%
Error level = 5% (1 - 95%)
Since the probability that the machine says the pipe has a problem for a site that in fact has an issue = 95% and the pipe has a problem in 10% of the case, this means that the pipe has a problem in exactly 0.095 (10% * 95%).
Therefore, the probability that a site has no problem when the machine says that the pipe at the site has no issue = 0.905 (1 - 0.095).

N is between M and P find the value of x help :(
Answer: x = 20
Step-by-step explanation: We can use the Segment Addition Postulate.
If N is between M and P, then MN + NP = MP.
So we have 2x + 7 + 13 = 3x.
Solving from here, first simplify the left side to get 2x + 20 = 3x.
Now subtract 2x from both sides ti get 20 = x.
So the value of x is 20.
3/4x+5−1/2x=3 what is the value of x?
Answer:
-1/8 is the answer
Step-by-step explanation:
1.) 1st we have to take 1/2x and make the bottom number 4. so we multiply by 2 and you should get 2/4.
2.) so now the equation should be 3/4x + 5 -2/4x = 3. now you take 3/4x and -2/4x and subtract them and you should get 1/4x.
3.) now the equation should look like 1/4x + 5 = 3. now we need to get all whole numbers to one side. so we will subtract 5 from 5 and that will cancel it out and we need to do that to both sides. so we will subtract 5 from 3 and you will get -2.
4.) now the equation should look like 1/4x = -2. now you put a 1 under the 2 to make it a fraction. it should look like 2/1 and then you are going to flip it because that is how you divide fractions. so now your equation should look like 1/4x = 1/2. now you multiply strait across both bottom and top. and you will get x = -1/8 and that is your answer.

Jason enters six races: biking, canoeing, horseback riding, ice skating, running, and swimming. He places between first and fifth in each. Two places are consecutive only if the place numbers are consecutive. Jason's places in canoeing and running are consecutive. His places in ice skating and swimming are consecutive. He places higher in biking than in horseback riding. He places higher in canoeing than in running.
1. If Jason places higher in running than in biking and places higher in biking than in ice skating and swimming, which one of the following allows all six of his race rankings to be determined?
a. He places fourth in horseback riding.
b. He places fourth in ice skating.
c. He places the same in both horseback riding and ice skating.
d. He places the same in both horseback riding and swimming.
e. He places higher in horseback riding than in swimming.
If Jason places higher in running than in biking and places higher in horseback riding than in ice skating, exactly how many of his rankings can be determined?
a. 2
b. 3
c. 4
d. 5
e. 6
Answer:
1) e: He places higher in horseback riding than in swimming.
2) e: 6
Step-by-step explanation:
1)If Jason places higher in running than in biking and places higher in biking than in ice skating and swimming, which one of the following allows all six of his race rankings to be determined?
We are told in the question that:
Two places are consecutive only if the place numbers are consecutive.
Therefore, Option e. He places higher in horseback riding than in swimming. Is that one that allows all his race rankings to be determined is correct
2)If Jason places higher in running than in biking and places higher in horseback riding than in ice skating, exactly how many of his rankings can be determined?
From the above comprehension, we are told that Jason entered six races: which are as follows: biking, canoeing, horseback riding, ice skating, running, and swimming.
Therefore, since he entered 6 races, each races would have a ranking of their own. Hence, the number of his rankings that can be determined is 6.
Option e is correct.
1. e: He places higher in horseback riding than in swimming
2. e: 6
We're given:
canoeing and running are consecutive (which means they cannot be separated with other middle number and that they do not overlap). ice skating and swimming are consecutive rank in biking is higher than in horseback riding (which means they cannot be overlapped but can be separated by middle ranks).rank in canoeing > rank in runningFirst question gives:
running rank > biking rankbiking rank > ice skating rankThis situation if mixed with point e :
Horseback riding rank > rank in swimming
Then this is what we get:
Canoeing = 1st position
Running = 2nd position
biking = 3rd position
Ice Skating = Horseback riding = 4th rank (overlapped since overall he can only have all 6 ranks from first to fifth)
Swimming = 5th rank
Thus option e allows all six of his races rankings to be determined.
Second condition gives:
1. Rank in running > rank in biking
2. Rank in Horseback riding > rank in swimming
This implies that
canoeing rank > running rank > biking rank > horseback riding > swimming
And since ranks cannot go outside from first to fifth position and since ice skating is consequent to swimming thus we have:
canoeing rank = 1
running rank = 2
biking rank = 3
horseback riding rank = ice skating ranking= 4
swimming rank = 5
Thus option e is correct as all the six rankings are determined.

Answer:
The probability that exactly 2 out of the first 10 customers buy a magazine
=
1.92%
Step-by-step explanation:
The Proportion of customers who buy a magazine = 9.6%
If 2 out of the first 10 customers buy a magazine, the proportion is given as 2/10 or 20%.
Therefore, the probability that exactly 2 out of the first 10 customers will buy a magazine is equal to the proportion of customers who buy a magazine multiplied by the proportion of the first 10 customers who buy a magazine
= 9.6% * 20%
= 1.92%
