Answer:
10.2% but there is a chance of it being 8.8%
Step-by-step explanation:
there are total of 18 marbles to start
of this at the begining there is a 8/18 chance to draw a marble, now here is where it can get tricky so ive organized them into different groups, A and B
Option A: The Marbles are removed after
this would make the problem be 8/18 x 7/17 x 6/16
4/9 x 7/17 x 3/8 or 84/1224
simplify 42/612
simplify 21/306
(21/306) x 100 = 10.2%
Option B: The Marbles arent removed after
8/18 x 8/18 x 8/18
4/9 x 4/9 x 4/9
64/729 = .08779
.08779 x 100 = 8.8
8.8%
It depends on what youve learned in class, i would go with option A

please help me complete these -5a^2+ 5a = _______(a – 1) and 18x^2 + 2x³ = _______(9 + x) I need to complete the blanks
Answer:
Step-by-step explanation:
-5a^2+ 5a factors as follows: -5(a - 1) (so -5 goes into the blank space).
18x^2 + 2x³ factors as follows: 2x^2(x + 9) (so 2x^2 goes into the blank space)

Answer:
The interval is [4,7]
Step-by-step explanation:
The rate of change is given by
f(x2) - f(x1)
-------------------
x2 -x1
We want the rate of change to be 56
f(x2) - f(x1)
------------------- = 56
x2 -x1
We also know that the x2 is 7 so f(x2) = 192
192 - f(x1)
------------------- = 56
7 -x1
192 - f(x1) = 56( 7 -x1)
192 - f(x1) = 392 -56x1
Now we need to pick points from the table and see where it is true
(6,96)
192 - 96 = 392 -56*6
96=56 False
( 5,28)
192 - 28 = 392 -56*5
164=112 False
(4,24)
192 - 24 = 392 -56*4
168=168 True
The interval is [4,7]
Find the volume of a right circular cylinder that has a radius of 3 inches and a height of 8 inches.
Answer:
Volume, V = 75.41 cubic inches.
Step-by-step explanation:
Given the following data;
Radius, r = 3 inches
Height = 8
To find the volume of the right circular cylinder;
Mathematically, the volume of a right circular cylinder is given by the formula;
V = πr²h
Where;
V is the volume of a right circular cylinder.r represents the radius of the cylinder.h represents the height of the cylinder.Substituting into the formula, we have;
Volume, V = 3.142 * 3 * 8
Volume, V = 3.142 * 24
Volume, V = 75.41 cubic inches.

a window is shaped like a semicircle and has diameter of 2 feet which expression describes the perimeter in feet of the window
Answer:
5.14 ft
Step-by-step explanation:
The perimeter of a circle is diameter X 3.14. since its half a circle, take the radius and multiply by 3.14. Since the radius is 1, the answer is pi itself. Then add 2 feet for the flat side of the semi-circle
A student has a total of 233 points on three tests. The scores on the first and second tests are the same. The third score exceeds the second (or the first) by 14. Find the three scores.
Answer:
Let the scores on the first two test be x
Let score for third test be 14 exceeds second( or first) = x + 14
Total = 233
x + x + (x + 14) = 233
3x + 14 = 233
3x = 219
x = 73
Score of the third test = x + 14 = 73 + 14 = 87
Therefore, the scores are 73, 73, 87

THIS IS AREA OF CIRCLES PLS ANSWER
Answer:
75ft^2
Step-by-step explanation:
A = pi*r^2
The circle already gives the diameter and the diameter is two times the radius, so if you were to divide the diameter by two, you would get 5.
Knowing the radius is 5 and seeing how they replaced pi with 3 we can set up the equation.
3*(5)^2 = A
Simplify
3*25
Multiply
Area=75ft^2
Factorise fully [tex]3y^{3} -12y[/tex]
Answer:
[tex] {3y}^{3} - 12y \\ = 3y( {y}^{2} - 4) \\ = 3y( {y}^{2} - {2}^{2} ) \\ = 3y(y - 2)(y + 2) \\ = 3y(y + 2)(y - 2)[/tex]
a^2-b^2=(a+b)(a-b)
a=y b=2

Determine the approximate value of ø
a)41.89
b) 48.20
c)33.70
d)56.30
Answer:
B,48.2
Step-by-step explanation:
To solve this we need to use SOH, CAH, TOA
we have the adjacent and hypotonouse so it's easiest to use CAH
let theta (angle) = x
cos(x)=4/6
to cancel the cos mulitply both sides by cos^-1 (2nd --> cos)
x=48.1896851
which rounds to 48.2

A new drug cures 65% of the patients who take it. If it is given to 14 patients, what is the probability that at least 12 will be cured?
Answer:
[tex]P(X \geq 13) = 0.021[/tex]
Step-by-step explanation:
From the question we are told that:
Probability of curing patients P(x)=0.65
Sample size n=14
Generally the Binomial equation is mathematically given by
[tex]P(X) =\frac{(n!)}{X!(n-X)!))} *p^X*(1-p)^(n-X)[/tex]
Generally the equation for Equation for at least 12 cured is mathematically given by
[tex]P(X \geq 13) = P(X = 13)+P(X = 14)[/tex]
For [tex]P(X = 13)[/tex]
[tex]P(X = 13) = (14!/(13!(14-13)!))*0.65^13*(1-0.65)^(14-13) \\\\P(X = 13)= 0.018116[/tex]
For [tex]P(X = 14)[/tex]
[tex]P(X = 14) = (14!/(14!(14-14)!))*0.65^14*(1-0.65)^(14-14) \\\\P(X = 14)= 0.00240318[/tex]
Therefore
[tex]P(X \geq 13) =P(X = 13)+P(X = 14)[/tex]
[tex]P(X \geq 13) = 0.018116+0.00240318[/tex]
[tex]P(X \geq 13) = 0.02051918[/tex]
[tex]P(X \geq 13) = 0.021[/tex]
