What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface.
The radius of cylinder is r=8 inches
Height is 0.5 feet.
Surface area of cylinder=2πr(r+h)
We know that 0.5feet=6 inches
Suface area of original cylinder=2πr(r+h)
=2×π×8(8+6)
=224π
Now the dimensions are doubled ,so r=16 inches , h=12 inches
Suface area of changed cylinder=2πr(r+h)
=2π×16(16+12)
=32π×(28)
=896π
=4(224π)
Hence by 4 factor the surface area is changed.

Find the cost of 12 items if the cost function is C(x) = 2x +12
Answer:
$36
Step-by-step explanation:
we need to find the cost of 12 items, and the function of determining the cost is C(x)=2x+12, where x is the number of items (the input value of the function)
we know that there are 12 items, so in this function, x=12
substitute x as 12 in the function; the x in C(x) also gets substituted as 12, as 12 is the input value and the value of C(x) is the output
C(12)=2(12)+12
multiply
C(12)=24+12
add
C(12)=36
that means, for 12 items, the cost will be $36

Answer:
4,670.61 Dollars
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 2.5/100
r = 0.025 rate per year,
Then solve the equation for A
A = Pert
A = 2,500.00(2.71828)(0.025)(25)
A = $4,670.61

In a charity marathon to raise money for Typhoon Ulysses, Alex finished 43rd out of 200 entrants. Find his percentile rank.
The percentile rank in a charity marathon to raise money for Typhoon Ulysses is 21.5 percentile.
What is the Percentile?A percentile (or a centile) is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations fall. For example, the 20th percentile is the value (or score) below which 20% of the observations may be found.
Rank of Alex is 43rd
Total Entrants is 200
Percentile = Rank of Alex X 100 / Total Entrants
= 43 X 100 / 200
= 21.5 percentile
Thus, the percentile rank in a charity marathon to raise money 21.5 percentile.

x<3 is the solution of the equation 3 + (x-2) / (x-3) ≤ 4.
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
The given equation can be rewritten as 3 + (x-2) / (x-3) ≤ 4.
To solve for x, we need to multiply both sides by (x-3)
3(x-3) + (x-2) ≤ 4(x-3).
3 + x-2/x-3 -4 ≤ 0
Solve the above equation.
-1 + x-2/x-3 ≤ 0
-(x-3) + x-2/x-3 ≤ 0
1/x-3 ≤ 0
x-3 < 0
x < 3
Hence, x<3 is the solution of the equation 3 + (x-2) / (x-3) ≤ 4.

A study is conducted to determine the extent to which drinking alcohol impairs driving ability. Forty volunteers are each tested twice on a computer simulated driving course, once while sober and once while intoxicated. The tests took place over two days and the order of the treatments were randomly assigned to each volunteer. One of the variables measured is the response time (in seconds) to a certain stimuli. The mean difference in response times measured while intoxicated versus sober is 0.914 seconds with standard deviation 1.496 seconds. Specify the correct number from the list below that corresponds to the appropriate null and alternative hypotheses for this problem.
Answer: hello the list related to your question is missing hence i will give you a general answer that will enable to pick the correct option from the list you have.
answer :
The correct number from the list that corresponds to the null hypothesis will be a number ≥ P - value / critical value
The correct number form the list that corresponds to the alternate hypothesis will be a number ≤ P - value / critical value
Step-by-step explanation:
Determine the null and alternative hypothesis
Mean difference = 0.914
standard deviation = 1.496
duration of test = 2 days
n ( sample size ) = 40
assuming 99% confidence interval
critical value = 2.708 ( using excel function : TINV (0.01, 40 - 1 ) )
Given that the aim of the experiment is to determine the effect of alcohol on driving ability
H0 : μ : Impairs driving
Ha : μ : does not impair driving
Note :
when the P-value is ≤ significance level we reject the Null hypothesis
while when the P-value is ≥ significance level we reject the alternate hypothesis
The correct number from the list that corresponds to the null hypothesis will be a number ≥ P - value / critical value
The correct number form the list that corresponds to the alternate hypothesis will be a number ≤ P - value / critical value

Write down the gradient of a line parallel to the line drawn below...
Answer:
[tex]\rm Slope = -1[/tex]
Step-by-step explanation:
Given :-
A equation of line .[tex]\rm y = -x-3[/tex]And we need to find out the gradient of the line. parallel to the given line .The gradient of the line is the " slope " of the line. The given equation is in slope Intercept Form , which is ,
Slope intercept form :-
[tex]\rm\implies y = mx + c [/tex]
Where m is the slope of the line and c is y intercept .On comparing it to slope Intercept Form , we have ,
[tex]\implies \rm Slope (m) = (-1)[/tex]
And the slope of the line , parallel to a line is same as that of the given line. Therefore they will have same gradient.
[tex]\implies \boxed{\rm Slope_{(||\ line)} (m) = (-1)}[/tex]
Hence the gradient of the line is (-1) .
