Answer:
8x + 4y
here's your solution
=> (10x + 3y) - (2x - 4y)
=>. now multiple - to (2x - 4y)
=> hence we get -2x + 4y
=> now put this in above
=> 10x +3y -2x + 4y
=> solve for common terms
=> 8x + 7y

what are the major limitations of statistics
Answer: Statistics laws are true on average. Statistics are aggregates of facts, so a single observation is not a statistic. Statistics deal with groups and aggregates only.

1. Sarah's current account balance is $2,600. She made a single lump sum amount of
$2,000 eight years ago into the account. Calculate the equivalent simple interest
rate (quoted annually) that she earned.
Answer:
The simple interest that said investment yielded was 3.75% per year.
Step-by-step explanation:
Given that Sarah's current account balance is $ 2,600, and she made a single lump sum amount of $ 2,000 eight years ago into the account, to calculate the equivalent simple interest rate (quoted annually) that she earned the following calculation must be performed:
(2,600 - 2,000) / 8 = X
600/8 = X
75 = X
2,000 = 100
75 = X
75 x 100 / 2,000 = X
7,500 / 2,000 = X
3.75 = X
Thus, the simple interest that said investment yielded was 3.75% per year.

James works from 2pm until 8:30pm on both Thursday and Friday. He is paid £12 per hour. On Saturday, he is paid 1 and 1/2 times his hourly pay. He works for 5 hours on Saturday. Calculate how much James earns in TOTAL for these three days.
9514 1404 393
Answer:
£246
Step-by-step explanation:
James works 8:30 -2:00 = 6: 30 hours on Thursday and Friday, for a total of 2×6:30 = 13:00 hours.
James works 5 hours on Saturday, but gets paid for 5×(1 1/2) = 7.5 hours. Then for the three days, he gets paid for 13 +7.5 = 20.5 hours.
James's total pay for the three days is ...
(20.5 h)(£12/h) = £246 . . . . pay for 3 days
_____
Additional comment
The associative property of multiplication says you can associate the factor 1 1/2 either with the hours or the pay:
(5 h)((1 1/2)(£12/h)) = ((5 h)(1 1/2))(£12 /h)
The computation involving "time and a half" often calculates the pay separately for overtime hours. I sometimes find it easier to calculate the pay for overtime by increasing the hours, rather than the pay.

The measurements of a circular object are given in the ratio table.
a. Find the missing dimensions of other circular objects by completing the ratio table.
b. Graph the pairs of values.
Answer:
after 42 mm the next one is 63mm and after 198mm it is 946mm
Step-by-step explanation:
The Diameter of the second circle is 63 mm and the circumference of the third circle is 946.
What is circumference?The circumference of a circle is the distance along a line across it. In other words, the length of a straight line created by opening a circle matches the radius of the circle. The formula to calculate circumference is C = π * Diameter.
Given that circumference of the first circle is 198mm by that we can drive the value of the diameter(D₂). from the formula of the circumference
C = π D₂
198 = 3.14 * D₂
D₂ = 63mm.
Given that the Diameter of the first circle is 198mm by that we can drive the value of the circumference. from the formula of the circumference
C₃ = π D₃
C₃ = 3.14 * 301
C₃ = 946 mm.
Therefore, the missing dimensions of the circular object are D₂ is 63mm and C₃ is 946mm.

Find the area of this composite figure
Answer:
23.9425 (Round if needed)
Step-by-step explanation:
This is 2 half circles so you can find the area of a circle and divide it by 2.
First circle has a diameter of 6 cm
6/2=3 cm
So, circle has radius of 3.
Area of circle= 3.14(pi) radius^2
3.14 x 3^2= 28.26
28.26/2=14.13 cm
Area of first half circle= 14.13
Repeat that process for the second circle.
3.14 x 2.5^2=19.625
19.625/2=9.8125
14.13+9.8215=23.9425
Area=23.9425
If x represents the age of the father and
y represents the present age of the son,
then the statement for 'present age of
the father is 5 more than 6 times the
age of the son' in terms of a
mathematical equation is *
Answer:
x = 5+6y
Step-by-step explanation:
Let x represents the age of the father and y represents the present age of the son.
ATQ,
The present age of the father is 5 more than 6 times the age of the son. We can write it in the form of equation as follows :
6 times the age of the son means 6y. So,
x = 5+6y
Hence, the mathematical equation is "x = 5+6y".

Answer:
245 [tex]cm^{3}[/tex]
Step-by-step explanation:
Formula for volume: [tex]a^{2}[/tex] [tex]\frac{h}{3}[/tex]
a = base edge
Base edge = 7
h = height
Height = 15

(-42% - 27) - (-34x + 33)
Please help! What is the answer?
Answer: 6.4cm
Step-by-step explanation:
The area of a trapezoid is given as:
= 1/2(a + b)h
We then slot the given values into the formula. This will be:
1/2(15.8 + b) × 7.3 = 81.03.
7.3(15.8 + b)= 81.03 × 2
7.3(15.8 + b) = 162.06
115.34 + 7.3b = 162.06
7.3b = 162.06 - 115.34
7.3b = 46.72
b = 46.72/7.3
b = 6.4
Therefore, the answer is 6.4cm.
For which sample size (n) and sample proportion (p) can a normal curve be
used to approximate the sampling distribution?
Answer:
Option c.
Step-by-step explanation:
Using the normal curve to approximate a sampling distribution:
For a sample size n and a proportion n, the normal curve can be used if:
[tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex]
Option a:
[tex]np = 35*0.8 = 28 > 10[/tex]
[tex]n(1-p) = 35*0.2 = 7 < 10[/tex]
So option a cannot be used.
Option b:
[tex]np = 65*0.9 = 58.5 > 10[/tex]
[tex]n(1-p) = 65*0.1 = 6.5 < 10[/tex]
So option b cannot be used.
Option c:
[tex]np = 65*0.8 = 52 > 10[/tex]
[tex]n(1-p) = 65*0.2 = 13 > 10[/tex]
So option c can be used, and is the answer
Option d:
[tex]np = 35*0.9 = 31.5 > 10[/tex]
[tex]n(1-p) = 35*0.1 = 3.5 < 10[/tex]
So option d cannot be used.
The answer is given by option c.
