[tex]\boxed{\sf 200\pi}[/tex]
Step-by-step explanation:
We know that the volume of a cone:-
[tex]\boxed{\sf \pi r^2\cfrac{h}{3}}[/tex]
(r = 10) (h = 6)
[tex]\sf \pi \times 10^2\times\cfrac{6}{3}[/tex]
Divide numbers:-
[tex]\sf \cfrac{6}{3}=\boxed{2}[/tex]
[tex]\sf 10^2\times \:2\pi[/tex]
[tex]\sf 100\times \:2\pi[/tex]
Multiply numbers:-
[tex]\boxed{\sf 200\pi}[/tex]
Therefore, your answer is 200π³
We could also multiply 200 by 3.14 which will give you 628 units³.
Are you picky about the toilet paper you buy? James is! To investigate the absorbency power of his favorite
brand of toilet paper, he went to the store and randomly selected (and purchased) 18 single rolls. He then
poured 1/4 cup of water onto a hard surface and counted how many individual squares of toilet paper it took
to completely absorb the water. Here are the results from his 18 rolls:
29
29
20
24
25 29 21
27 28 21
24 27 25 24
25 26 22 23
(a) Is there convincing evidence at the a= 0. 05 significance level that this brand of toilet paper will
require less than 26 squares to absorb 1/4 cup of water?
(b) Referring to your conclusion, what type of error may have been made? Describe the error in the
context of this study.
There's no convincing evidence at 0.05 significance level that this brand of toilet paper will require less than 26 squares.
What is a significance level?A significance level simply means is the probability that an event has occured by chance.
In this case, there's convincing evidence at 0.05 significance level that this brand of toilet paper will require less than 26 squares to absorb 1/4 cup of water. Therefore, we fail to reject the null hypothesis.
A type of error that may have been made is type II error. This is the non rejection if the null hypothesis when it's false.

A basket contains 3 oranges and 7 apples.
Two pieces of fruit are selected at random, with replacement.
Find the probability that an orange is selected both times.
Answer:3/10
Step-by-step explanation:No matter what you have 3 oranges so regardless there will be a 30% chance.
The chance of picking an orange is 3/10, and since you’re picking twice with replacement this is represented as 3/10 * 3/10 = 9/100
9/100 or 9%

Kevin is 4 times as old as Daniel and is also 6 years older than Daniel.
How old is Kevin?
Answer:
kevin = 8 - hope this helped
:)
Step-by-step explanation:
Kevin = 4d Kevin is 4 times as old as Daniel
Kevin = d + 6 Kevin is 6 years older than Daniel
4d = d + 6 They both equal K, so they are equal
3d = 6 subtracts D from both sides
d=6/3 = 2
If Daniel is 2 then Kevin is 4x2=8
If Daniel is 2 then Kevin is 2+6 = 8
Kevin is 8
Daniel is 2

Answer:
31.6°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the trig function relating the sides opposite and adjacent an acute angle in a right triangle. It tells you ...
Tan = Opposite/Adjacent
__
The tangent of angle B is ...
tan(B) = AC/CB
tan(B) = 28.2/45.8
The angle is found from the tangent using the inverse tangent function.
B = arctan(28.2/45.8) ≈ 31.621°
The measure of angle B is about 31.6°.

Answer:
a) 8/11 x 5/3
b) It will be positive. When we have an even number of negatives, the result will be positive ( (-) + (-) = +).
Step-by-step explanation:
a) -8/11 / -3/5
1) -8/11 ÷ (-3/5)
Write the complex fraction as a division expression. Use parentheses because our second fraction is a negative.
2) 8/11 ÷ 3/5
When we have an even number of negatives, the result will be positive ( (-) + (-) = +).
3) 8/11 x 5/3
Dividing is the same as multiplying the second part of the fraction flipped.
4) 40/33
Multiply them: 8 x 5 / 11 x 3
Since the question wants you to write as a multiplication expression, this is the answer:
8/11 x 5/3.
which graph represents the inequality y < 2x +3 correctly
Answer:
im not sure , sorry
Step-by-step explanation:
Answer:
Option C
Step-by-step explanation:
Graphing inequality:
1) First plot y = 2x + 3 as a dotted line as y is less than x
Put x = 0, y = 2*0 +3 = 0 + 3 = 3 ⇒ (0, 3)
Put x = 1 , y = 2*1 + 3 = 2 +3 = 5 ⇒(1 , 5)
Put x = -1, y =2*(-1)+3 ⇒ -2+3 = 1 ⇒ (-1,1)
Mark these three points, and draw a dotted line.
2) Shade the area bellow the dotted line as y < 2x + 3
Check: take a point in the shaded area. (1 , -1)
-1 < 2*1 + 3
-1 < 2 +3
-1 < 5
The condition is satisfied.

The range Girls Choose
The mean Choose.
Answer:
RangeThe range of the data is the difference between the largest data value and the smallest data value.
Therefore, the ranges are:
Boys: 10 - 3 = 7
Girls: 9 - 5 = 4
So the boys have a larger range than the girls.
MeanTo calculate the mean, add up all the data values then divide by the number of values.
[tex]\textsf{Mean of Boys}=\dfrac{3+6+7+7+8+8+8+8+9+10}{10}=\dfrac{74}{10}=7.4[/tex]
[tex]\textsf{Mean of Girls}=\dfrac{5+6+6+6+7+7+7+8+8+9}{10}=\dfrac{69}{10}=6.9[/tex]
So the boys have a higher mean than the girls.
The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. If g(x) is obtained by shifting f(x) down by 5 units, then what is the value of k?
k equals one fifth
k = 5
k equals negative one fifth
k = −5
Answer:
k = 5
Step-by-step explanation:
Plugging in 5 for k turns out positive 5 into a negative 5 because of the negative sign in the function. When k is negative, then the graph moves down.
