Michael is organizing a game of chance for his class. He asks each student to pick a ribbon from a bag and then put it back into the bag. The bag
has 12 yellow ribbons, 7 red ribbons, and 3 blue ribbons. If Jane picks a ribbon, what is the probability that the ribbon will be yellow and what is
the likelihood of this event?
OA. The probability is 1, and the event is certain.
OB. The probability is î and the event is likely.
OC. The probability is it and the event is unlikely.
OD The probability is it, and the event is neither likely nor unlikely.
Answer:
b
Step-by-step explanation:
Using the probability concept, it is found that the correct statement regarding the probability of picking a yellow ribbon is given by:
D The probability is of 0.5454 = 54.54%, and the event is neither likely nor unlikely.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, 12 out of 22 ribbons are yellow, hence:
p = 12/22 = 6/11 = 0.5454 = 54.54.
The probability is greater than 0.05 but less than 0.95, hence it is neither likely nor unlikely, which means that option D is correct.

There are 510 calories in 100 g of Twix.
There are 45 calories in 100 g of Coca Cola.
Lionel has 60 g of Twix and 140 g of Coca Cola for a morning snack
Work out the total number of calories in this morning snack.
Answer:
Amount of calories in 60g of Twix and 140g of Coca cola = 1020 calories
Step-by-step explanation:
Given:
Amount of calories in 100 g of Twix = 510 calories
Amount of calories in 100 g of Coca cola = 45 calories
Find:
Amount of calories in 60g of Twix and 140g of Coca cola
Computation:
Amount of calories in 60g of Twix = 60[510/100]
Amount of calories in 60g of Twix = 306 calories
Amount of calories in 140g of Coca cola = 140[510/100]
Amount of calories in 140g of Coca cola = 714 calories
Amount of calories in 60g of Twix and 140g of Coca cola = 306 + 714
Amount of calories in 60g of Twix and 140g of Coca cola = 1020 calories

Answer:
(8n)(-77)=-77(n*8)
We move all terms to the left:
(8n)(-77)-(-77(n*8))=0
We add all the numbers together, and all the variables
8n(-77)-(-77(+n*8))=0
We multiply parentheses
-616n-(-77(+n*8))=0
We calculate terms in parentheses: -(-77(+n*8)), so:
-77(+n*8)
We multiply parentheses
-616n
Back to the equation:
-(-616n)
We get rid of parentheses
-616n+616n=0
We add all the numbers together, and all the variables

the product of the present ages of Two Sisters is 150. 5 years ago, the elder sister was twice as old as her younger sister find their age
The younger sister is 10 years old and the elder sister is 15 years old.
Let's represent the present ages of the two sisters as x and y, where x is the age of the elder sister and y is the age of the younger sister.
According to the given information, the product of their present ages is 150:
x * y = 150 ---(1)
It is also stated that 5 years ago, the elder sister was twice as old as her younger sister:
x - 5 = 2 * (y - 5) ---(2)
We can now solve these two equations simultaneously to find the ages of the two sisters.
From equation (2), we can simplify:
x - 5 = 2y - 10
x = 2y - 10 + 5
x = 2y - 5
Substituting this value of x into equation (1), we have:
(2y - 5) * y = 150
2y^2 - 5y = 150
2y^2 - 5y - 150 = 0
Now we can solve this quadratic equation either by factoring, completing the square, or using the quadratic formula. By factoring, we find:
(2y + 15)(y - 10) = 0
This gives us two possible solutions for y:
2y + 15 = 0 --> y = -7.5 (Discard this since age cannot be negative)
y - 10 = 0 --> y = 10
So, the younger sister is 10 years old.
To find the elder sister's age, we can substitute this value of y into equation (2):
x = 2y - 5
x = 2 * 10 - 5
x = 20 - 5
x = 15
Therefore, the elder sister is 15 years old.

Answer:
C. $37.39
Step-by-step explanation:
We have our original value, $37.69, and we are given a table that adds or subtracts a certain amount. The question is asking what is the final product by Friday.
To solve, all we have to do is subtract and add the price of stock per each day.
$37.69
On Tuesday, the stock price went up by $0.69 cents.
So we must add .69 to 37.69
37.69 + .69
38.38
On Wednesday, the stock price lowered by 82 cents.
So we subtract .82 from 38.38
38.38 - .82
37.56
On Thursday the stock price gained 37 cents, so do the same you did for Tuesday.
37.56 + .37
37.93
On Friday the stock price went down by 14 cents, so do the same you did for Wednesday.
37.93 - .14
37.79

I need help on this question!??
Answer:
The only thing you will do is to plug the x in the equation.
x = -2 ---> f(x) = -6
x = 0 ---> f(x) = 0
x = 3 ---> f(x) = 9
x = 7 ---> f(x) = 21
f(x) = 3x
f(-2) = 3(-2)
f(-2) = -6
f(0) = 3(0)
f(0) = 0
f(3) = 3(3)
f(3) = 9
21 = 3x
21 / 3 = 3x / 3
7 = x
Hope this helps, thank you :) !!

Both the quality of mangement and the reputation of the company were rated on an excellent, good, and fair catergorical scale. Assume sample data for 200 respondents below.
Reputation of Company
Quality of management Excellent Good Fair
Excellent 40 25 5
Good 35 35 10
Fair 25 10 15

B) If there is a dependence or association between the two ratings, discuss and use the probabilities to justify your answer.
Answer:
Hello some parts of your question is missing below is the missing part
answer : A) p-value = 0.0019 ,

Step-by-step explanation:
A) using a 0.05 level of significance and test for independence of the quality of management
Test statistic : [tex]X^{2}[/tex] ∑ ( Oi - Ei )^2 / Ei
= [(40-35)^2 / 35 ] + [(25-24.5)^2 / 24.5 ] + [(5-10.5)^2 / 10.5] + [(35-40)^2 / 40] + [(35-28)^2 / 28] + [(10-12)^2 / 12] + [ (25-25)^2 / 25 ] + [(10-17.5)^2 / 17.5 ] + [(15-7.5)^2 / 7.5] = 17.03
p-value = 0.0019
Df = 4 ,

Which number can each term of the equation be multiplied by to eliminate the fractions before solving? 6 1 -Xt 3 1 = } 2x+5 o 2 o 3 6 O 12
Correct question is;
Which number can each term of the equation be multiplied by to eliminate the fractions before solving? 6 – ¾x + ⅓ = ½x + 5
Answer:
12
Step-by-step explanation:
We are given the equation as;
6 – ¾x + ⅓ = ½x + 5
In order to find out the number that each term can be multiplied by, we will need to express each denominator as a product of its prime factors to find the lowest common factor.
Thus;
Factors of 4 = 1 × 2 × 2
Factors of 3 = 1 × 3
Factors of 2 = 1 × 2
Thus, LCF = 1 × 2 × 2 × 3 = 12

Given a right triangle ABC, if the measure of angle A is 77', and cos (77) = sin(0).
what is the value of 0 ?
==========================================================
Rule:
If cos(A) = sin(B), then A+B = 90
This can be proven through the use of drawing a right triangle with acute angles A and B. Let's say C is the 90 degree angle.
Then note how cos(A) = adjacent/hypotenuse = AC/AB while sin(B) = opposite/hypotenuse = AC/AB. We see that both evaluate to AC/AB. So this confirms cos(A) = sin(B) is true.
The condition that A+B = 90 is from from the fact that any pair of acute angles of a right triangle are complementary angles.
-------------------------
Using that rule, we can say
cos(77) = sin(theta)
leads to
77+theta = 90
and that solves to
theta = 90-77 = 13
