Answer:
996
Step-by-step explanation:
the three digit number is;
996
Step-by-step explanation:
The three digit can be written xyz
ones digit is equal to 1/3 the sum of the two other digits
z = 1/3(x + y)
x + y + z = 24
Tens digit is same as hundreds digit
That means x = y
z = 1/3 (x + x) = 2x/3
So;
2x/3 + x + x = 24
Multiply through by 3
2x + 3(2x) = 72
8x = 72
x = 72/8
x = 9
x = y = 9
z = 1/3(18)
z = 6
Solve for u.
-24 = u ÷ 6

2 Dylan is part of a volunteer crew constructing houses for low-income families. Dylan is experienced at installing tile floors. He is training a new volunteer, George, to complete tiling projects. A new job involves placing 100 tiles. Dylan knows from experience that it would take him 2 hours to complete the job if he were working alone. Dylan estimates that it would take George 4 hours to complete the job if George were working alone. If Dylan and George work together, how long will it take to complete the job?
Answer:
For the tiling Job; it takes the following for installing 100 tiles:
Dylan =2 hours
George = 4 hours
if they work together for the job, for 1 hour,
it would be the following no of tiles to be fixed:
Dylan + George = total tiles
100/2 + 100/4 = 50 + 25 = 75 tiles
If it takes George 1hr to fix 50 tiles,
For 30 minutes, Dylan will fix 25 tiles
Therefore Total tiles fixed = Dylan(1hr work) + George(1hr work) + Dylan (30mins work)
= 50 tiles + 25 tiles + 25 tiles = 100 tiles
Therefore, it will take approximately 1 hour for them to install 75 tiles in the low-income house for the families or
1.30 hours (1 hr, 30 minutes) to fix 100 tiles for the same low income families.

Answer:
C
Step-by-step explanation:
We are given that:
[tex]\displaystyle k(x)=\frac{f(x)}{g(x)}[/tex]
And we want to find k'(3).
So, let's find k'(x). Take the derivative of both sides. This will require the Quotient Rule. Hence:
[tex]\displaystyle k^\prime(x)=\frac{f^\prime(x)g(x)-f(x)g^\prime(x)}{(g(x))^2}[/tex]
We want to find k’(3). Substitute:
[tex]\displaystyle k^\prime(3)=\frac{f^\prime(3)g(3)-f(3)g^\prime(3)}{(g(3))^2}[/tex]
Using the table, make the appropriate substitutions:
[tex]\displaystyle k^\prime(3)=\frac{5(2)-(-1)(-2)}{(2)^2}[/tex]
Evaluate:
[tex]\displaystyle k^\prime(3)=\frac{10-2}{4}=\frac{8}{4}=2[/tex]
Therefore, our answer is C.
cloud is a vegetable grower, has 8 4/15 plots of pechay, 5 1/3 plots of eggplants and 5 2/5 of okra . how many plots of vetable do cloud has?
Answer:
The total plots of vegetable cloud will have: 19
Step-by-step explanation:
As the cloud has:
[tex]8\frac{4}{15}[/tex] plots of pechay[tex]5\frac{1}{3}[/tex] plots of eggplants[tex]5\frac{2}{5}[/tex] plots of okaraSo, the total plots of vegetable cloud will have:
[tex]8\frac{4}{15}+5\frac{1}{3}+5\frac{2}{5}[/tex]
[tex]=\frac{124}{15}+\frac{16}{3}+\frac{27}{5}[/tex]
[tex]=\frac{124}{15}+\frac{80}{15}+\frac{81}{15}[/tex]
[tex]=\frac{124+80+81}{15}[/tex]
[tex]=19[/tex]
Therefore, the total plots of vegetable cloud will have: 19
A 90% confidence interval for the mean height of a population is This result is based on a sample of size 169. Construct a 99%confidence interval.
This question is incomplete, the complete question is;
A 90% confidence interval for the mean height of a population is 65.7 < μ < 67.3
This result is based on a sample of size 169.
Construct a 99%confidence interval.
Answer: at 99%, confidence interval is [ 65.2, 67.8 ]
Step-by-step explanation:
Given that;
confidence level = 90%
∝ = 1 - 90% = 1 - 0.9 = 0.1
the mean height of a population is 65.7 < μ < 67.3
so
x" - t_∝/2, n-1{standard Error] = 65.7 ----let this be equation 1
x" + t_∝/2, n-1{standard Error] = 67.3 -----let this be equation 2
where t∝/2, n-1 = t_0.1/2, 169 - 1 = t_0.05, 168 = 1.654 (t table)
now we add equation one and equation two
2x" = 65.7 + 67.3 = 133
x" = 66.5
next we subtract equation one from equation two
(x" + t_∝/2, n-1{standard Error]) - (x" - t_∝/2, n-1{standard Error])
= 67.3 - 65.7 = 1.6
so
2 × t_∝/2,n-1 × standard Error = 1.6
standard Error = 1.6 / (2 × t_∝/2,n-1)
we substitute
Standard Error = 1.6 / ( 2 × 1.654 ) = 1.6 / 3.308 = 0.48367
Now 99% confidence interval for μ is given as;
∝ = 1 - 0.99 = 0.01
x" ± t_∝/2, n-1{standard Error]
(x" ± t_0.01/2, 169-1 [standard Error])
where t_0.005, 168 = 2.6054 (t table)
now for Lower Bound: (x" - t_0.005, 168 [standard Error])
Lower Bound : ( 66.5 - (2.6054 × 0.48367))
= 66.5 - 1.26015 = 65.2398
Upper Bound : ( 66.5 + (2.6054 × 0.48367))
= 66.5 + 1.26015 = 67.7602
Therefore at 99%, confidence interval is [ 65.2, 67.8 ]

6 2/6 x 1 1/2
(6 x 6) + 2 = 38/6
(1 x 2) + 1 = 3/2
38/6 x 3/2 = 114/12
114 ÷ 12 = 9 6/12.
9 6/12 = 9 3/6 = 9 1/2.
C
Again it can be simplified buts it not on here for some reason.

if a person is randomly selected from the US population, the odds the person lives in California are 1 to 8.
What is the probability of two decimal places of a randomly chosen person being from California?
What are the odds of a randomly chosen person not being from California?
Answer:
The probability of a randomly chosen person being from California is 0.111.
The probability of a randomly chosen person not being from California is 0.889.
Step-by-step explanation:
The odds of a person, selected from the US population, living in California is 1 to 8.
That is:
[tex]\text{Odds}(\frac{\text{Lives in California}}{\text{Does not Lives in California}})=\frac{1}{8}[/tex]
Compute the probability of a randomly chosen person being from California as follows:
[tex]P(\text{Lives in California})=\frac{\text{Odds}(\text{Lives in California})}{\text{Odds}(\text{Lives in California})+\text{Odds}(\text{Does not Lives in California})}[/tex]
[tex]=\frac{1}{1+8}\\\\=\frac{1}{9}\\\\=0.111[/tex]
The probability of a randomly chosen person being from California is 0.111.
Compute the probability of a randomly chosen person not being from California as follows:
[tex]P(\text{Love in California})=1-P(\text{Does not Love in California})[/tex]
[tex]=1-0.111\\\\=0.889[/tex]
Thus, the probability of a randomly chosen person not being from California is 0.889.
