Hiro rolls a fair pair of six-sided dice. The sample space of all possible outcomes is shown below.
Let AAA be the event that the first die is one and BBB be the event that the sum of the dice is eight.
What is P(A\text{ or }B)P(A or B)P, left parenthesis, A, start text, space, o, r, space, end text, B, right parenthesis, the probability that the first die is one or the sum of the dice is eight?
\qquad
Answer: [tex]\dfrac{11}{36}[/tex]
Step-by-step explanation:
Total outcomes for rolling a pair of six-sided dice n(S)= 6 x 6 =36
Let A be the event that the first die is one and B be the event that the sum of the dice is eight.
A = {(1,1), (1,2), (1,3), (1,4), (1,5), (1,6)}
P(A)= [tex]=\dfrac{n(A)}{n(S)}=\dfrac{6}{36}[/tex]
B= {(2,6), (6,2), (3,5), (5, 3), (4,4)}
P(B)= [tex]=\dfrac{n(B)}{n(S)}=\dfrac{5}{36}[/tex]
A ∩ B = Ф
P(A ∩ B)=0
P(A or B)= P(A)+P(B)+P(A∩ B)
[tex]=\dfrac{6}{36}+\dfrac{5}{36}+0\\=\dfrac{11}{36}[/tex]
Hence, P(A or B) = [tex]\dfrac{11}{36}[/tex]

HELP!!!! HURRY PLEASE
the length of a rectangle is 6 meters more than its width. if the area of the rectangle is 135 square meters, find its dimensions, PLease provide step by step info
Answer:
length 15 width 9
Step-by-step explanation:
Then the length can be represented by the following expression: (x + 6)
Since area is equal to length times width, we can write the following equation for the area:
A = length * width
135 = (w + 6) * w
Now we can solve for w after using the distributive property and factoring:
135 = (w + 6) * w
135 = w^2 + 6w
0 = w^2 + 6w - 135
This factors to:
0 = (w + 15) (w -9)
w = -15 OR w = 9
Required information Skip to question A die (six faces) has the number 1 painted on two of its faces, the number 2 painted on three of its faces, and the number 3 painted on one of its faces. Assume that each face is equally likely to come up. If the die were loaded so that the face with the 3 on it were twice as likely to come up as each of the other five faces, would this change the value of P(odd number)
Answer:
The change to the face 3 affects the value of P(Odd Number)
Step-by-step explanation:
Analysing the question one statement at a time.
Before the face with 3 is loaded to be twice likely to come up.
The sample space is:
[tex]S = \{1,1,2,2,2,3\}[/tex]
And the probability of each is:
[tex]P(1) = \frac{n(1)}{n(s)}[/tex]
[tex]P(1) = \frac{2}{6}[/tex]
[tex]P(1) = \frac{1}{3}[/tex]
[tex]P(2) = \frac{n(2)}{n(s)}[/tex]
[tex]P(2) = \frac{3}{6}[/tex]
[tex]P(2) = \frac{1}{2}[/tex]
[tex]P(3) = \frac{n(3)}{n(s)}[/tex]
[tex]P(3) = \frac{1}{6}[/tex]
P(Odd Number) is then calculated as:
[tex]P(Odd\ Number) = P(1) + P(3)[/tex]
[tex]P(Odd\ Number) = \frac{1}{3} + \frac{1}{6}[/tex]
Take LCM
[tex]P(Odd\ Number) = \frac{2+1}{6}[/tex]
[tex]P(Odd\ Number) = \frac{3}{6}[/tex]
[tex]P(Odd\ Number) = \frac{1}{2}[/tex]
After the face with 3 is loaded to be twice likely to come up.
The sample space becomes:
[tex]S = \{1,1,2,2,2,3,3\}[/tex]
The probability of each is:
[tex]P(1) = \frac{n(1)}{n(s)}[/tex]
[tex]P(1) = \frac{2}{7}[/tex]
[tex]P(2) = \frac{n(2)}{n(s)}[/tex]
[tex]P(2) = \frac{3}{7}[/tex]
[tex]P(3) = \frac{n(3)}{n(s)}[/tex]
[tex]P(3) = \frac{1}{7}[/tex]
[tex]P(Odd\ Number) = P(1) + P(3)[/tex]
[tex]P(Odd\ Number) = \frac{2}{7} + \frac{1}{7}[/tex]
Take LCM
[tex]P(Odd\ Number) = \frac{2+1}{7}[/tex]
[tex]P(Odd\ Number) = \frac{3}{7}[/tex]
Comparing P(Odd Number) before and after
[tex]P(Odd\ Number) = \frac{1}{2}[/tex] --- Before
[tex]P(Odd\ Number) = \frac{3}{7}[/tex] --- After
We can conclude that the change to the face 3 affects the value of P(Odd Number)

45 Tyrone is converting 50 to a percent. Which method should he use to find the percent? Divide the numerator and denominator of the fraction by 2. Subtract 40 from the numerator and denominator of the fraction. Multiply the numerator and the denominator of the fraction by 2. Add 50 to the numerator and denominator of the fraction.
Answer:
3. multiply the numerator and denominator of the fraction by 2
Step-by-step explanation:
Multiplying the numerator and denominator by 2 is like multiplying the fraction by 2/2. 2/2 is one so it doesn't change the value.
Answer:
❌Divide the numerator and denominator of the fraction by 2.
❌Subtract 40 from the numerator and denominator of the fraction.
✔️Multiply the numerator and the denominator of the fraction by 2.
❌Add 50 to the numerator and denominator of the fraction.

The firm is requested to send 3 employees who have positive indications of asbestos on to a medical center for further testing. Suppose 40% of the employees have positive indications of asbestos in their lungs. a) Find the probability that exactly 10 employees will be tested in order to find 3 positives
Answer:
0.0645 = 6.45% probability that exactly 10 employees will be tested in order to find 3 positives
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
40% of the employees have positive indications of asbestos in their lungs
This means that [tex]p = 0.4[/tex]
a) Find the probability that exactly 10 employees will be tested in order to find 3 positives
2 within the first 9([tex]P(X = 2)[/tex] when [tex]n = 9[/tex]), and the 10th, with 0.4 probability. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{9,2}.(0.4)^{2}.(0.6)^{7} = 0.1612[/tex]
0.4*0.1612 = 0.0645
0.0645 = 6.45% probability that exactly 10 employees will be tested in order to find 3 positives

Step-by-step explanation:
Use the GCF and the Distributive Property to
rewrite the following expression:
24 +30
Answer:
B = 6(4 + 5)
Step-by-step explanation:
GCF = The greatest common factor, example: GCF of 12 and 16 = 12 is divisible by all of these numbers. The factors for 16 are 1, 2, 4, 8, 16. The two numbers (12 and 16) share common factors (1, 2, 4). The greatest of these is 4 and that is the greatest common factor.
Distributive property = allows us to multiply the number by a group of numbers, which are added together. The distributive property is given by: a(b+c) = ab + ac
The Greatest Common Factor of 24 and 30 is 6 because it is the largest number they have together (24 = 6*4 and 30 = 6*5)
24 divided by 6 = 4
30 divided by 6 = 5
This fits B the most: 6(4 + 5)
The answer is B, I hope this helps!
Suppose that a company wishes to predict sales volume based on the amount of advertising expenditures. The sales manager thinks that sales volume and advertising expenditures are modeled according to the following linear equation. Both sales volume and advertising expenditures are in thousands of dollars.
Estimated Sales Volume =46.63+0.47(Advertising Expenditures)
If the company has a target sales volume of $275,000, how much should the sales manager allocate for advertising in the budget?
Answer:
$485890
Step-by-step explanation:
Given
Estimated Sales Volume =46.63+0.47(Advertising Expenditures)
Required
Find the allocated amount for advertising expenditure when target sales is $275000
Represent the sales volume with V and The advertising expenditure with a.
So, the expression is:
[tex]V = 46.63 + 0.47A[/tex]
Since the expression is in thousands, substitute 275 for V
[tex]275 = 46.63 + 0.47A[/tex]
Collect Like Terms
[tex]275 - 46.63 = 0.47A[/tex]
[tex]228.37= 0.47A[/tex]
Make A the subject
[tex]A = \frac{228.37}{0.47}[/tex]
[tex]A = 485.89[/tex]
Hence, $485890 should be allocated for advertising

If y = 5x-2 were changed to y = 3x-2how would the graph of the new
function compare with the first one?
Hi there! The answer is B. it would be less steep.
The change of the function (in this case) influences the slope of the line. Since we've modified the slope from 5 to 3/4, the line will be less steep.
