Answer: 0.023
Step-by-step explanation:
Given that:
Number of green balls = 9
Number of white balls = 8
Total number of balls = 9 + 8 = 17
Drawing with replacement :
Probability of white :
First draw = 8/17
2nd draw = 8/17
3rd draw =. 8/17
4th draw = 8/17
5th draw = 8/17
P(all 5 are white) = 8/17 * 8/17 * 8/17 * 8/17 * 8/17 = 32768/1419857
= 0.0230783
= 0.023

A new process for producing a type of novolac resin is supposed to have a mean cycle time of 3.5 hours per batch. Six batches are produced, and their cycle times, in hours, were 3.45 3.47 3.57 3.52 3.40 3.62. Can you conclude that the mean cycle time is greater than 3.5 hours
Answer:
Yes, the mean cycle time is greater than 3.5 hours
Step-by-step explanation:
Let us try to calculate the mean cycle time here. Consider the given cycle times. To obtain the mean cycle time, we have.
3.45 + 3.47 + 3.57 + 3.52 + 3.40 + 3.62/6 = 3.505 hours
Hence the difference 3.505 -3.5 = 0.005
Hence mean cycle time is greater than 3.5 by 0.005

A piece of charcoal used for cooking is found at the remains of an ancient campsite. A 0.8 kg sample of carbon from the wood has an activity of 1770 decays per minute. Find the age of the charcoal. Living material has an activity of 15 decays/minute per gram of carbon present and the half-life of 14C is 5730 y. Answer in units of y
Answer:
t = 15825.11 years
Step-by-step explanation:
From the given information:
We can make use of the activity of the sample present after time "t" to determine the age of the sample.
This can be expressed by the formula:
[tex]A = A_o e^{-\lambda t}[/tex] --- (1)
where;
[tex]A_o[/tex]= activity of the sample at time t = 0
[tex]\lambda[/tex] = disintegration constant
[tex]\lambda = \dfrac{0.693}{T_{1/2}}[/tex]
If we replace the value of [tex]\lambda[/tex] into equation (1), we have:
[tex]A = A_o e^{ \Bigg [ -{ \dfrac{0.693}{T_{1/2}} \Bigg ] } t}[/tex]
[tex]\dfrac{A}{A_o} = e^{ \Bigg [ -{ \dfrac{0.693}{T_{1/2}} \Bigg ] } t}[/tex]
By rearrangement:
[tex]t = \dfrac{-T_{1/2} In (\dfrac{A}{A_o})}{0.693}[/tex]
[tex]t = - \dfrac{\left(5730\ \cdot\ \ln\left(\frac{\left(1770\right)}{0.8\cdot10^{3}\cdot15}\right)\right)}{0.693}[/tex]
t = 15825.11 years
Which is the completely factored form of 12x3 – 60x2 + 4x – 20? 4(3x2 – 1)(x – 5) 4x(3x2 + 1)(x – 5) 4x(3x2 – 1)(x + 5) 4(3x2 + 1)(x – 5)
Answer:
The answer is 4(3x² + 1)(x - 5).
Step-by-step explanation:
First, you have to take out all the common ratios :
12x³ - 60x² + 4x - 20
= 4(3x³ - 15x² + x - 5)
Next, you have to factorize the inner brackets :
3x³ - 15x² + x - 5
= 3x²(x - 5) + (x - 5)
= (3x² + 1)(x - 5)
Answer:
4(3x² + 1)(x - 5)
Step-by-step explanation:
Given
12x³ - 60x² + 4x - 20 ← factor out 4 from each term
= 4(3x³ - 15x² + x - 5)
Factor the first/second and third/fourth terms inside the parenthesis
= 4[ 3x²(x - 5) + 1(x - 5) ] ← factor out (x - 5) from each term
= 4(3x² + 1)(x - 5)

Answer:
The m<PML + m<PMQ + m<QMN = 180° since they are supplementary
therefore,
45°+(6x-5)+x=180°
45+7x-5=180
40+7x=180
7x=140
x=20
To test it we should plug in x for each equation and the sum of those answers should equal 180
45+(6x20-5)+20=180?
45+115+20=180?
160+20=180?
180=180
x=20 is valid

Use the number line to represent all the solutions to the inequality -3(2j-11)>=8j-9.
Select a ray. Move the point on the ray to the correct place on the number line.
The solution to the inequality -3( 2j - 11 ) ≥ 8j - 9 can be represented in an inequality form or interval notation form as j ≤ 3 and (-∞,3] respectively.
What is the solution to the given inequality?Given the inequality in the question;
-3( 2j - 11 ) ≥ 8j - 9
First, we simplify using distributive property.
-3( 2j - 11 ) ≥ 8j - 9
-3×2j -3×-11 ≥ 8j - 9
-6j + 33 ≥ 8j - 9
Next, move all terms containing j to the left and all constant to the right.
-6j + 33 ≥ 8j - 9
-6j - 8j ≥ - 9 - 33
-14j ≥ -42
Divide both sides by -14.
Note that, when multiplying or dividing both sides of an inequality by a
negative value, the inequality sign flips directions.
-14j/-14 ≤ -42/-14
j ≤ -42/-14
j ≤ 3
Therefore, The solution to the inequality -3( 2j - 11 ) ≥ 8j - 9 can be represented in an inequality form or interval notation form as j ≤ 3 and (-∞,3] respectively.

5. Sasha is signing her daughter up for dance classes. There is a one-time
costume fee of $35 and each dass costs $15. Sasha paid a total of $155.
how many classes did she sign up for?
Answer:
She paid for 8 classes
Step-by-step explanation:
Take away $35 from $155 because it was a one time custom fitting. And they’re asking for how many classes. So 35-155=120. Now you didvide 15 (charge per class) by 120 (total for all classes). And your answer is 8 classes. Hope this helped :)

Given x=1/2 and y=-x, what is the value of x-y
Answer:1
Step-by-step explanation:x=1/2 , y =-1/2
X-y = 1/2-(-1/2)=1
Answer:
x-y = 1
Step-by-step explanation:
Question: Given x = 1/2 and y = -x, what is the value of x - y?
Step-by-step:
We know that x = 1/2 and y = -x but we need to find out what -x is equal to.
To find the value of -x, we need to multiple -1 on both sides of the equation: x = 1/2
(You can think of it like -1 acts like an invisible number)
x*-1 = 1/2*-1 which is -x = -1/2
Since y is equal to -x, y = -1/2
We need to find x - y which is 1/2 - (-1/2)
Because the negative and subtraction signs cancel out, we add instead. The equation becomes 1/2 + 1/2
One half + half = 1
Therefore, x-y = 1

It takes Evan 3/4 hour to mow his backyard how much will the yard be mowed after 2/3 hour
Answer:
88.88% or 8/9 of the yard is mowed
Step-by-step explanation:
First step is to get the denominator to the same number. Both denominators have a least common multiple of 12.
3/4 * 3/3 = 9/12
2/3 * 4/4 = 8/12
9/12 hours is how long it takes Evan to mow his backyard. He has 8/12 hours of work already done. If we divide the time already passed by the time still needed to mow the backyard, we can get how much of the yard is already mowed.
(8/12) / (9/12)
8/12 * 12/9
96/108 = 88.88
