Share R600 amongst Tom, Paul and Anne in the ratio : 3:4:5 respectively.
Step-by-step explanation:
Total Shares = 3 + 4 + 5 = 12 shares
12 Shares = R600
(12÷12) Share = R(600÷12)
1 Share = R50
(1×3) Shares = R(50×3)
3 Shares = R150
4 Shares = R(50×4) = R200
5 Shares = R(50×5) = R250
Tom Gets R150.
Paul gets R200.
Anne gets R250.

Suppose that a random sample of eighteen recently sold houses in a certain city has a mean sales price of , with a standard deviation of . Under the assumption that house prices are normally distributed, find a confidence interval for the mean sales price of all houses in this community. Then find the lower limit and upper limit of the confidence interval.
This question is incomplete, the complete question is;
Suppose that a random sample of eighteen recently sold houses in a certain city has a mean sales price of $280,000, with a standard deviation of $10,000. Under the assumption that house prices are normally distributed, find a 95% confidence interval for the mean sales price of all houses in this community. Then find the lower limit and upper limit of the confidence interval.
Answer:
At 95%, confidence interval is ( 275026.7, 284973.3 )
Hence;
Lower limit = 275026.7
Upper limit = 284973.3
Step-by-step explanation:
Given that;
mean x = $280,000
standard deviation σ = $10,000
sample size n = 18
degree of freedom df = n - 1 = 18 - 1 = 17
∝ = 1 - 95% = 1 - 0.95 = 0.05
so
Critical t value = tinv( 0.05, 17 ) = 2.11
now, at 95% confidence interval for mean will be;
⇒ x ± [ Critical t value × ( σ/√n) ]
so we substitute
⇒ 280,000 ± [ 2.11 × ( 10000/√18) ]
⇒ 280,000 ± [ 2.11 × 2357.0226 ]
⇒ 280,000 ± 4973.3
⇒ 280000 - 4973.3, 280000 + 4973.3
At 95%, confidence interval is ( 275026.7, 284973.3 )
Hence;
Lower limit = 275026.7
Upper limit = 284973.3

help please :((( this is the last math problem
Answer:
11.53 degrees.
Step-by-step explanation:
ok so we know the hyp and opp sides. this means that it is sin. according to SOHCAHTOA we do sin^-1(2/10). you should get 11.53
Answer:
11.5396°
Step-by-step explanation:
Please see the attached image
We can do sin(x)=2/10, which simplifies to sin(x)=1/5
To get x by itself do [tex]x=sin^{-1}[/tex](1/5) which ≈11.5396°

HELP PLEASE A total of 29 bills amounts to $73.00. If there are only $1 and $5 bills, how many of each are there?
Answer:
18 $1 bills and 11 $5 bills.
Step-by-step explanation:
First, we use the guess-and-check method.
$5X29=$145
Then, $5-$1=$4.
$145-$73=$72
$72 divided by 4 is 18.
29-11=18
11x$5=$55
$1x18=$18
$55+18=73.
18. Emma rents a car from a company that rents cars by the hour. She has to pay an initial fee of $75, and then they charge her $9 per hour. Write an equation for the total cost Cif Emma rents the car for h hours. If Emma has budgeted $250 for the rental cars, how many hours can she rent the car? Assume the car cannot be rented for part of an hour.
Step-by-step explanation:
Let h be the number of hours.
Total Cost = Fixed Costs + Variable Cost
= Initial Fee + Hourly Charge
= 75 + 9h
Given,
[tex]75 + 9h = 250 \\ 9h = 250 - 75 \\ 9h = 175 \\ h = 175 \div 9 \\ = 19 \frac{4}{9} hr[/tex]
Since the car cannot be rent part of an hour, the highest possible whole number is 19 hours.
find the the ratio write the answer as a fraction and as a decimal rounded to four decimal places.
Answer:
7 degrees
Step-by-step explanation:
It has a right angle and it's a triangle so the angle is a complementary angle so the total for the angle is 90 degrees.
So then you add 39 + 44 and get 83
So, 90 - 83 +7
So your total is 7 degrees

( 7x + 1/2) + ( 7x - 7 and 1/2) Simplify
Answer:
The answer will be 7(2x - 1)
Step-by-step explanation:
1) Convert 7 and 1/2 to improper fraction. Use this rule: a b/c = ac + b/c
[tex]7x + \frac{1}{2} + 7x - \frac{7 \times 2 + 1}{2} [/tex]
2) Simplify 7 × 2 to 14 .
[tex]7x + \frac{1}{2} + 7x - \frac{14 + 1}{2} [/tex]
3) Simplify 14 + 1 to 15.
[tex]7x + \frac{1}{2} + 7x - \frac{15}{2} [/tex]
4) Collect like terms.
[tex](7x + 7x) + ( \frac{1}{2} - \frac{15}{2} )[/tex]
5) simplify.
[tex]14x - 7[/tex]
6) Factor out the common term 7.
[tex]7(2x - 1)[/tex]
Therefor, the answer is 7( 2x - 1 ).

Answer:
y=9.75x+60
Step-by-step explanation:
We want our equation to look like y=mx+b
Let's start out by calculating the slope
[tex]\frac{118.5-89.25}{6-3}=9.75[/tex]
we have
y=9.75x+b
we know that when x= 3 y= 89.25
89.25=9.75(3)+b
solve for b = 60
