Answer:
The volume of the cylinder is about 1256.6 cubic meters.
Step-by-step explanation:
The volume of a cylinder is given by the formula:
[tex]\displaystyle V=\pi r^2h[/tex]
Where r is the radius and h is the height.
Our radius is 10 meters and our height is four meters. Substitute:
[tex]\displaystyle V=\pi(10)^2(4)[/tex]
Evaluate:
[tex]V=400\pi \text{ m}^3\approx 1256.6\text{ m}^3[/tex]
Thus, the volume of the cylinder is about 1256.6 cubic meters.

The time, T (seconds) it takes for a pot of water to boil is inversely proportional to the cooker setting, H ,applied to the pot.
When H=6 T=90.
What must the cooker setting be if it takes 5 minutes to boil the water?
Answer:
[tex]1.8[/tex]
Step-by-step explanation:
Since the time for the pot of water to boil is inversely proportional to the cooker setting, H, as one goes up, the other must go down:
[tex]T\propto \frac{1}{H}[/tex]
Convert 5 minutes to seconds:
[tex]5\cdot 60=300\:\mathrm{s}[/tex]
Therefore, from the initial data given (When H=6, T=90), the new time is [tex]\frac{300}{90}=3\frac{1}{3}[/tex] larger. Therefore, H must be [tex]3\frac{1}{3}[/tex] times smaller for them to be inversely proportional.
[tex]H=\frac{6}{3\frac{1}{3}}=\boxed{1.8}[/tex]
A box contains 4 marbles: 1 blue, 1 yellow, 1 green, and 1 white. A marble is randomly drawn from the box and a number cube, labeled 1 through 6, is tossed. What is the probability of getting a yellow marble and an odd number? Express as a fraction in simplest form.
Answer:
The answer is 1/8
Step-by-step explanation:
There are 4 marbles in the box and one of them is a yellow marble. The odds of getting a yellow marble fr the box is 1/4.
A number cube labeled 1 through 6 has 6 numbers, which are 1, 2, 3, 4, 5 and 6. The odd numbers in the cube are 1, 3 and 5. The probability of getting an odd number from the cube is 3/6, which is simplified to 1/2.
To find the probability of both cases occurring, both fractions should be multiplied.
1/4 * 1/2 = 1/8

A start-up company is about to market a new computer printer. It decides to gamble by running commercials during the Super Bowl. The company hopes that name recognition will be worththe high cost of the ads. The goal of the company is that over 40% of the public recognize its brand name and associate it with computer equipment. The day after the game, a pollster contacts 420 randomly chosen adults and finds that 181 of them know thatthis company manufactures printers. Would you recommend that the company continue to advertise during Super Bowls
Reject the null hypothesis and come to the conclusion that there is enough evidence to imply that the percentage of adults who are familiar with the company's name is much more than 40%.
What is the null hypothesis?In order to evaluate whether the percentage of individuals who recognize the company's brand name differs considerably from the company's target of 40%, we must conduct a hypothesis test.
Let p represent the percentage of adults who can name the company's brand. The corporation hopes that more than 40% of adults will recognize its brand name, hence the alternative hypothesis is that p > 0.4.
A one-sample z-test can be used to examine this claim. The test statistic is determined as follows:
[tex]z = \dfrac{(p' - p)} { \sqrt{\dfrac{(p (1 - p)} { n}}}[/tex]
Where p is the null hypothesis value, n is the sample size, and p is the sample proportion.
In this instance, n = 420, p = 0.4, and p' = 181/420 = 0.431. With these values entered into the formula, we obtain:
[tex]z = \dfrac{(0.431 - 0.4)} { \sqrt{(0.4 \times \dfrac{0.6} { 420} }}= 1.65[/tex]
The likelihood of obtaining a z-value of 1.65 or higher is 0.0495 using a basic normal distribution table or calculator (assuming the null hypothesis is true). This is the test's p-value.
When the p-value is less than 0.05, which is considered to be significant (and corresponds to a 95% confidence level), we
Hence, based on this sample of 420 adults, we would advise the company to keep running Super Bowl advertisements as it seems to be succeeding in raising brand recognition among the general public.

A)
(x – 3)
B)
(x + 2)
C)
(x + 3)
D)
(x – 2)
Answer:
c. (x + 3)
Step-by-step explanation:
using factor theorem
if x - 3 is a factor then p(a) = 0
p(a)= x^3 - 3x^2 - 4x + 12
a.(x-3)
p(3) = (3)^3 - 3(3)^2 - 4(3) + 12
= 27 - 27 - 12 + 12
= 0
therefore x-3 is a factor
b.(x + 2)
p(-2) = (-2)^3 - 3(-2)^2 - 4(-2) + 12
= -8 -12 + 8 + 12
,= 0
therefore x + 2 is a factor
c.(x + 3)
p(-3) = (-3)^3 - 3(-3)^2 - 4(-3) + 12
= -27 -27 + 12 + 12
= -30
therefore x + 3 is not a factor
d.(x-2)
p(2) = (2)^3 - 3(2)^2 - 4(2) + 12
= 8 -12 - 8 + 12
= 0
therefore x - 2 is a factor

6. The word ‘COMMITTEE’ has 9 letters.
So it can be permuted in 9 ways, but we’ve got letters repeating there. To avoid the same arrangements happening again, we eliminate the repetitions.
M repeats twice. T Twice. E twice.
7. If it must be greater than 2000 , the first digit must either be 2 or 3 , which means you will have 2 choices. After that, there will be 3 choices for the second digit. Then there will be 2 choices for the third digit. Lastly there will be just 1 choice for the last digit.

The sum of two numbers is -5. The difference is
13. What is the smaller number?
Answer:
The smaller number is -9.
Step-by-step explanation:
Let x and y be the two unknown numbers.
Their sum is -5. Hence:
[tex]x+y=-5[/tex]
Their difference is 13. Hence:
[tex]x-y=13[/tex]
This yields a system of equations. We can solve this using elimination. Adding the two equations together:
[tex](x+y)+(x-y)=(-5)+(13)[/tex]
Simplify:
[tex]2x=8[/tex]
Divide both sides by two. Thus:
[tex]x=4[/tex]
Using either equation (I'll use the first):
[tex](4)+y=-5\Rightarrow y=-9[/tex]
So, our two numbers are 4 and -9.
The smaller number is -9.

I'm new to this and I dont really understand this
Answer:
So starting off with 1a f(4)
We simply substitute x with 4 for the function
f(4)=2(4)-5
f(4)=8-5
f(4)=3
Next 1b, here it's a little different since you have to multiply the functions I think ( please correct me if I'm wrong).
gf(4), basically means functions g and f are being multiplied and their variables are being substituted with 4.
g(4)=4^2+3
g(4)=16+3
g(4)=19
and we also know from before that f(4)=3, so we'll do 19 times 3 which is 57
For the next two, I may be wrong, but I'm still going to try:
anything to the power of a negative is a fraction so for f^-1(x)=2x-5 we'll have 1/f(x)=x/2+5/2
And then for g^-1, we'll have 1/g(x)=[tex]\sqrt{x-3} \sqrt{x-3}[/tex]

The time t required to drive a certain distance varies inversely with the speed, r. If it takes 4 hours to drive the distance at 40 miles per hour, how long will it take to drive the same distance at 55 miles per hour?
A. about 2.91 hours
B. about 160.00 hours
C. about 22.00 hours
D. about 5.50 hours
Answer:
option D
Step-by-step explanation:
4 hours = 40 miles/per hour
? hour = 55 miles/per hour
step one, find rate :
40 divided by 40
1 hour = 10 miles/per Hour
If 4 x 10 = 40
then n x 10 = 55
It takes 5.5 OR 5.50 Hours/per hour for a Distance of 55 miles

1.836
6/50
Answer:
41% is already in percentage form.
1.836 is 183.6 %
6/50 is 12%.
Step-by-step explanation:
41% is already in percentage form, so I'm just going to leave that as it is.
1.836 has 1 whole already, so we know it's going to be more than 100%. Than we have that extra 83.6, so that would be 183.6% as a decimal.
6/50, well we divide to get 0.12, and 0.12 as a percent is 12%.
