Step-by-step explanation:
1)Probability of A NOT occuring: P(A') 0.7
Probability of B NOT occuring: P(B') 0.5
Probability of A and B both occuring: P(A∩B) 0.15
Probability that A or B or both occur: P(A∪B) 0.65
Probability that A or B occurs but NOT both: P(AΔB) 0.5
Probability of neither A nor B occuring: P((A∪B)') 0.35
Probability of A occuring but NOT B: 0.15
Probability of B occuring but NOT A: 0.35

Twice a number is equal to 35more than 7 times the number .find the number
Answers
Answer:
the number is -7
Step-by-step explanation:
so the equation looks like this
[tex]2x= 35+7x\\\\[/tex]
twice the number equals 35 more than 7 times the number
now solver for x
[tex]2x-7x = 35\\\\-5x = 35\\\\x = -7[/tex]
and the number is -7
[tex]2(-7) = 35+7(-7)\\\\-14 = 35-49\\\\-14 =-14[/tex]

Sam has a rectangular rug with an area of 48 square feet. The rug is 8 feet longer than it is wide. What is the width of the rug?
Answers
Given:
Arear of rectangular rug = 48 sq. feet.
The rug is 8 feet longer than it is wide.
To find:
The width of the rug.
Solution:
Let x feet be the width of the rug.
The rug is 8 feet longer than it is wide.
Length of the rug = (x+8) feet
Area of a rectangle is
[tex]Area=Length\times Width[/tex]
Arear of rectangular rug is 48 sq. feet.
[tex]48=(x+8)\times x[/tex]
[tex]48=x^2+8x[/tex]
[tex]0=x^2+8x-48[/tex]
Splitting the middle term, we get
[tex]x^2+12x-4x-48=0[/tex]
[tex]x(x+12)-4(x+12)=0[/tex]
[tex](x+12)(x-4)=0[/tex]
Using zero product property, we get
[tex](x+12)=0\text{ and }(x-4)=0[/tex]
[tex]x=-12\text{ and }x=4[/tex]
Width cannot be negative. So, [tex]x=4[/tex].
Therefore, the width of the rug is 4 feet.

To solve the problem, a proportion would be best!
First, let's set up the left side of the proportion. Percents, when used in parts, are always part of 100%, making 100% a whole. We'll use both 10% and 100% as our first fraction, which should look something like this:
[tex]\frac{10p}{100w}[/tex] (with p standing for part and w standing for the whole)
Next, let's set up the right side of our proportion. We'll use the 40 for our part and x for our whole since that is the number we are solving for. The proportion should now look like this:
[tex]\frac{10p}{100w} = \frac{40p}{x}[/tex]
To solve, just cross multiply and divide! Multiply 40 by 100 to give you 4,000. Next, divide 4,000 by the remaining 10 to give you a final answer of 400. If 40 passengers on the flight are in first class, then there are 400 total passengers. Hope this helps!

Ethan's football team scored a total of 35 separate times this season, with a mix of touchdowns and field
goals. Each touchdown is worth 7 points, and each field goal is worth 3 points. If the team scored a total of
193 points this season, how many touchdowns and field goals did they score?
Answers
9514 1404 393
Answer:
22 touchdowns13 field goalsStep-by-step explanation:
Let t represent the number of touchdowns scored. Then 35-t is the number of field goals, and the total score is ...
7t +3(35 -t) = 193
4t = 88 . . . . . . . . . . simplify, subtract 105
t = 22
35 -t = 13
The team scored 22 touchdowns and 13 field goals.

If you flip a coin and roll a 666-sided die, what is the probability that you will flip a heads and roll a 2?
Answers
Answer: [tex]\dfrac1{12}[/tex]
Step-by-step explanation:
Outcomes for tossing a coin =2 [tail and head]
Outcomes of rolling a 6-sided die =6
Total outcomes for rolling both = 2 x 6 = 12
Favorable outcomes for getting a head and 2 on die = 1
Probability = [tex]\dfrac{favorable\ outcome}{Total\ outcomes}[/tex]
Now , the probability that you will flip a heads and roll a 2 [tex]=\dfrac1{12}[/tex]
Hence, the required probability = [tex]\dfrac1{12}[/tex]
