Answer:
V = 235.5
or V = 75π
Step-by-step explanation:
V=πr^2h
Volume of a cylinder is (pi)(radius)(radius)(height)
V = (3.14)(5)(5)(3)
V = 235.5
Or, since it said you can leave it as pi,
V = 75π

Step-by-step explanation:
The N71-90 virus will give an infected person a mild rash on their arms once the person has 1 billion of the virus cells in their body. After an initial infection with just one cell, each virus cell will divide into two cells every four hours. After 30 divisions there are 1,073,741,824 cells and the rash starts. Once the rash starts, the immune system kicks in and kills all of the virus cells within an hour. The number of virus cells in the body can be determined using the function below.
v(h)=2\frac{h}{4}
In this function, h is the number of hours after infection. If Jolene is infected by one virus cell, how many virus cells will she have after 8 divisions?
A. 4
B. 256
C. 512
D. 8
Answer:
B. 256Step-by-step explanation:
Given function:
v(h) = 2^(h/4)It can be rewritten as:
v(d) = 2^d, where d- number of divisionsIf number of divisions is 8, then:
v(8) = 2^8 = 256 virus cellsCorrect choice is B
Answer:
Solution given:
v(h)=[tex] {2}^{\frac{h}{4}}[/tex]
we can write it as
v(d)=[tex] {2}^{d} [/tex]
now
v(8)=[tex] {2}^{8} [/tex]=256 virus cells will she have after 8 divisions.

Scott wants to buy fencing to place around a semicircle rock garden. The diameter of the semicircle is 16 feet. Using 3.14 as pie, he calculates that he needs to buy about 25.12 feet of fencing. The fencing is sold by the foot, so he plans to buy 26 feet of fencing.
Explain why Scott’s reasoning is incorrect.
FIND THE CORRECT ANSWER (IMPORTANT)
Answer:
Scott is wrong because he did not add the diameter that connects the arc
the fence is 41.12 feet. He would buy 42 feet
Step-by-step explanation:
Circumference of a semicircle = πr + d
π = pi = 3.14
d = diameter = 16
r = radius = 16/2 = 8
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
( 3.14 x 8) + 16 = 41.12 feet

Find the volume of the solid. (FSSS!) Round answers to the nearest hundredth.
Answer:
x = 9.27 cm
Volume = 289.2 cm³
Step-by-step explanation:
SA = Surface Area
SA = 229.2 cm²
P = Perimeter of Base
P = 3(6)
P = 18 cm
H = Height of Solid
H = x
A = Area of Base(Equilateral Triangle)
A = 6²√3 / 4
A = 36√3 / 4
A = 9√3
A = 9(1.732)
A = 31.176
A = 31.2 cm²
SA = Surface Area
SA = PH + 2A
229.2 = 18x + 2(31.2)
229.2 = 18x + 62.4
229.2 - 62.4 = 18x
166.8 = 18x
9.266 = x
9.27 = x
x = 9.27 cm
V = Volume
V = AH
V = 31.2(9.27)
V = 289.224
V = 289.2 cm³

Macy rolls a fair eight sided die with sides numbered from 1 to 8. Then from a box, she draws a numbered slip of paper. The slips of paper have numbers shown below.
1,2,5,7,8
Finally, she calculates the sum of her results.
Select all the true statements.
1.)A sum equal to 8 is the result 20 times in 80 rounds. This suggests the game is unfair.
2.)The probability of getting a sum that is a multiple of 3 is 3/8
3.) The probability of getting a sum that is even is 1/2.
4.) The probability of getting a sum that is greater than or equal to 12 is 11/40.
5.) The probability of getting a sum that is less than 10 is 21/40
There can be multiple answers
Probabilities are used to determine the chances of an event. The true statements from the 5 options are:
Probability that multiple of 3 is [tex]\frac{3}{8}[/tex]Probability of even sum is [tex]\frac{1}{2}[/tex]Probability of a sum greater than or equal to 12 is [tex]\frac{11}{40}[/tex]Given that:
[tex]Die =\{1,2,3,4,5,6,7,8\}[/tex]
[tex]Number = \{1,2,5,7,8\}[/tex]
The possible outcomes are:[tex]S = \{(1,1),(1,2),(1,5),(1,7),(1,8),(2,1),(2,2),(2,5),(2,7),(2,8),(3,1),(3,2),(3,5),(3,7),(3,8)\\(4,1),(4,2),(4,5),(4,7),(4,8),(5,1),(5,2),(5,5),(5,7),(5,8),(6,1),(6,2),(6,5),(6,7),(6,8),\\(7,1),(7,2),(7,5),(7,7),(7,8),(8,1),(8,2),(8,5),(8,7),(8,8)\}[/tex]
The sum of the outcomes are:
[tex]S = \{2,3,6,8,9,3,4,7,9,10,4,5,8,10,11,5,6,9,11,12,6,7,10,12,\\13,7,8,11,13,14,8,9,12,14,15,9,10,13,15,16\}[/tex]
Rearrange
[tex]S = \{2,3,3,4,4,5,5,6,6,6,7,7,7,8,8,8,8,9,9,9,9,9,10,10,10,10,11,11,11,\\12,12,12,13,13,13,14,14,15,15,16\}[/tex]
[tex]n(S) = 40[/tex]
Next, we test the options
(1) The game is unfair
The question implies that the eight sided die is fair. This means that the game is fair.
Option (1) is false.
(2) Probability that multiple of 3 is [tex]\frac{3}{8}[/tex]
The multiples of 3 in the sample space are:
[tex]3's = \{3,3,6,6,6,9,9,9,9,9,12,12,12,15,15\}[/tex]
[tex]n(3's) =15[/tex]
The probability is then calculated as:
[tex]P(3's) = \frac{n(3's)}{n(S)}[/tex]
[tex]P(3's) = \frac{15}{40}[/tex]
Simplify
[tex]P(3's) = \frac{3}{8}[/tex]
Option (2) is true
(3) Probability of even sum is [tex]\frac{1}{2}[/tex]
The even outcomes are:
[tex]Even =\{2,4,4,6,6,6,8,8,8,8,10,10,10,10,12,12,12,14,14,16\}[/tex]
[tex]n(Even) = 20[/tex]
The probability is then calculated as:
[tex]P(Even)= \frac{n(Even)}{n(S)}[/tex]
[tex]P(Even)= \frac{20}{40}[/tex]
Simplify
[tex]P(Even)= \frac{1}{2}[/tex]
Option (3) is true
(4) Probability of a sum greater than or equal to 12 is [tex]\frac{11}{40}[/tex]
The outcomes of a sum greater than or equal to 12 are:
[tex]Sum \ge 12 = \{12,12,12,13,13,13,14,14,15,15,16\}[/tex]
[tex]n(Sum \ge 12) = 11[/tex]
The probability is then calculated as:
[tex]P(Sum \ge 12) =\frac{n(P(Sum \ge 12)}{n(S)}[/tex]
[tex]P(Sum \ge 12) =\frac{11}{40}[/tex]
Option (4) is true
(5) Probability of a sum less than 10 is [tex]\frac{21}{40}[/tex]
The outcomes of a sum less than 10 are:
[tex]Sum < 10 = \{2,3,3,4,4,5,5,6,6,6,7,7,7,8,8,8,8,9,9,9,9,9\}[/tex]
[tex]n(Sum < 10) = 22[/tex]
The probability is then calculated as:
[tex]P(Sum < 10) =\frac{n(P(Sum < 10)}{n(S)}[/tex]
[tex]P(Sum < 10) =\frac{22}{40}[/tex]
Option (5) is false
Hence, the true statements are: options 2, 3 and 4.

Answer:
right triangle
Step-by-step explanation:
To test for a right triangle, use the Pythagorean theorem.
Let the legs, a and b, be the two shorter sides, and let the hypotenuse, c, be the longest side.
a² + b² = c²
a² + b² = 7.2² + 9.6² = 51.84 + 92.16 = 144
c² = 12² = 144
Since a² + b² = c², the triangle is a right triangle.

A spinner has an equal chance of landing on either red blue or green. You spin six times. What is the probability that spinner lands on red at least two times?
Answer:
0.8906 ( 4 decimal places)
Step-by-step explanation:
With an equal probability of landing in either blue or red, then
Probability of success, p = 0.5
Number of trials, n = 6
Probability of landing on red atleast twice Can be obtained using a cumulative binomial probability ;
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x ≥ 2) = p(x = 2) + p(x = 3) + p(x = 4) + p(x = 5) + p(x = 6)
Obtaining the individual probabilities and summing them up or we could use a cumulative probability option on either a calculator, excel or an online binomial probability distribution.
Using an online binomial probability calculator :
P(x ≥ 2) = 0.890625
P(x ≥ 2) = 0.8906 ( 4 decimal places)

Step-by-step explanation:
take out the parantheses
2x + 6 = x - 4
Put the variable on the left side of the ecuation with the opposite sign
