Numerele a,b,c sunt rationale si verifica egalitatea 3a+4b=c-36. Determinati cele trei numere daca a si b sunt direct proportionale cu 4 si 3,iar b si c sunt invers proportionale cu 0,24 si 0,01
Answers
Answer:
a/4 = b/3 = k
a=4k
b=3k
0.24=24/100=6/25
0.01=1/100
6b/25 = c/100 = k'
b=25k'/6=3k =>k'=18k/25
c=100k'=72k

Suppose you borrow money for a year at a simple interest rate of 7.2%. You pay $86.40 in interest. How much have you borrowed?
Answers
Answer:
$1200
Step-by-step explanation:
You want to know the amount borrowed at 7.2% if the simple interest for one year is $86.40.
InterestThe interest formula is ...
I = Prt
where P is the amount borrowed, r is the interest rate, and t is the number of years.
ApplicationUsing the given values, we have ...
86.40 = P·0.072·1
P = 86.40/0.072 . . . . . . divide by the coefficient of P
P = 1200
You have borrowed $1200.
Answer: 1200
Step-by-step explanation: Linear equation. 7.2x = 100(86.40). then divide by 7.2 on each side. x=1200

Please have step by step!!!
Answers
Answer:
$21,700
Step-by-step explanation:
$115,000 - 98,000
$115,000 - 98,000 = 17000
Credit Card Balance = Money owed
17000 - 2300
17000 - 2300 = 14700
Cars worth = +
14700 + 5800
14700 + 5800 = 20500
Bank Acc = +
20500 + 900
20500 + 900 = 21400
Gift Cards = +
21400 + 300 = 21700
I hope this helps <3Sorry if i'm late T-THave a great day :DIn the data set below, what is the interquartile range?
23 58 58 64 76 87
Answers
Answer: IQR= 18
Step-by-step explanation:
First, you need to put the numbers in order from least to greatest, which they already are.
23, 58, 58, 64, 76,87
then, you draw an imaginary line down the middle of the numbers (between 58 and 64), and then you find the number in the middle of these. The Q1 is 58, and the Q3 is 76. In order to find the Interquartile range (IQR), you simply subtract the two.
76-58= 18
And you have your answer
Hope this helps!
Answer:
44
Step-by-step explanation:
First, we need to find the median in the data set.
It's between 58 and 64. To find the median, we add those two numbers and then divide by 2.
58 + 64 = 122
122 ÷ 2 = 61 (Mark this point in between the numbers on the data set)
median = 61
23, 58, 58, | 64, 76, 87
Now that we have the median, we have to find the upper quartile and the lower quartile in order to find the interquartile range.
Lets find upper quartile first. In order to do that, add up all the numbers to the right of the data set from the median point, then divide by 2.
64 + 76 + 87 = 227
227 ÷ 2 = 113.5
The same goes for the lower quartile (to the left).
23 + 58 + 58 = 139
139 ÷ 2 = 69.5
Lastly, to find the interquartile range, simply subtract the lower quartile from the upper quartile.
113.5 - 69.5 = 44
Therefore interquartile range = 44.

24. At a company picnic, 1/2 of the people are employees. 2/5 are employees' spouses. What percent are neither?
Answers
Answer:
One half of X are employees.
One third of X are employee's spouses.
We add one half PLUS one third:
1/2 + 1/3 = 3/6 + 2/6 = 5/6
Then we subtract that fraction from one whole, or 1,
to see what fraction is left. That is, we say
1 minus 5/6
which is
1 - 5/6
Now write 1 as 6/6
6/6 - 5/6
We get 1/6
So 1/6 is left. Now we need to make that into
a percent by multiplying it by 100 and tacking on a "%"
1/6 � 100
1/6 � 100/1
100/6
50/3
16 2/3 %
So 16 2/3 % of the people in
attendance are neither employees
nor employee's spouses.
Now let's check:
1/2 are employees. That's 50%
1/3 are wmployee's spouses. That's 33 1/3%
15 2/3 % are neither employees nor employee's spouses.
Add them up
50 %
33 1/3 %
16 2/3 %
--------
99 3/3 %
And 99 3/3% = 100%
Step-by-step explanation:

Find the percent error in this situation:
Estimated value: 1081
Actual value: 1150
Answers
So 1150 (measured by the experiment) - 1081 (the estimate = theory)/1081 = 69/1081 = 0.0638 x 100 = 6.38%
The percentage error in the situation, where Estimated value 1081
and Actual value 1150 is, 6%
What is the percentage?The percentage is a mathematical term, which means a number or a ratio which is represented in fractions of 100. We use the '%' symbol to represent the percentage.
Formula for percentage;
Percentage = (present quantity/whole quantity)×100
Given that,
Estimated value: 1081
Actual value: 1150
Percentage error = [Actual value - Estimated value]/Actual value×100
= [1150 - 1081]/1150×100
= 6
Hence, the percentage error is 6%

For a randomly selected driver, are the events "driving while using a cell phone" and "having a traffic accident" independent events? Explain your answer. PLEASE HELP :(
Answers
Answer:
Let's denote:
The event of driving while using a cell phone: A
The event of having a traffic accident: B
The event of driving while using a cell phone and having a traffic accident: A⋂B
P(A) = 11% = 0.11
P(B) = 5.26% = 0.526
P(A⋂B) = 28% = 0.28
If event A and event B are independent (it means the cause of a traffic accident is nothing related to driving while using a cell phone), then:
P(A) x P(B) = P(A⋂B)
Let's check:
P(A) x P(B) = 0.11 x 0.526 = 0.05786 and not equal to P(A⋂B) = 0.28
=> Event A and event B are not independent. In other words, they are related. (it means driving while using a cell phone is one of the reasons for having a traffic accident)
