The spinner below has three regions: $5, $0, and $10. To play the game, you spin one time and then you win the amount in the region that the spinner lands on. a.) What is the expected value for the game? b) If you have to pay $10 to play, is it a fair game? *
a) $5.00 b) no
a) $4.79 b) yes
a) - $ 8.75 b) no
a) $ 3.00 b) yes
Answer:
$5.00 ; no
Step-by-step explanation:
Given that:
135 / 360 = 0.375
90 / 360 = 0.25
135/ 360 = 0.375
X ___ 5 _____10 _____ 0
P(x): _0.25___0.375___0.375
Expected value :
ΣX*p(X) :
5(0.25) + 10(0.375) + 0(0.375)
1.25 + 3.75 + 0
= $5
b) If you have to pay $10 to play, is it a fair game?
For the game to be fair :
Amount paid = Expected winning
$10 ≠ $5
Since, amount paid is greater than expected winning, then the game is not fair

A family car is being tested for fuel efficiency. It drives non-stop for 100 miles and uses 3.2 gallons of gasoline. Which of the following is the rates of distance traveled to fuel used?
Answer:
31.25miles per gallon
Step-by-step explanation:
Distance traveled = 100miles
Quantity of gasoline used = 3.2gallons
Unknown:
Rates of distance traveled to fuel used = ?
Solution:
The rates of distance traveled to fuel used is given as;
Rates = [tex]\frac{distance traveled}{fuel used }[/tex]
Input the parameters and solve;
Rates = [tex]\frac{100}{3.2}[/tex] = 31.25miles per gallon

5/3x+6=2/9x
Please answer x as a fraction
Answer:
x = -4 2/13
x = -4.15384615385
x = -54/13
(they are all the same, just in different formats)
Step-by-step explanation:
(5/3x) + 6 = (2/9)x
first, make all "x"s have a common denominator
(5/3) = (15/9)
so
(5/3)x = (15/9)x
(15/9)x + 6 = (2/9)x
solve using inverse operations
(15/9)x + 6 = (2/9)x
-(2/9)x -(2/9)x
(13/9)x + 6 = 0
-6 -6
(13/9)x = -6
to get rid of the fraction, multiply the entire equation by the denominator
(13/9)x = -6
*9 *9
13x = -54
/13 /13
x = -4 2/13
x = -4.15384615385
x = -54/13
(they are all the same, just in different formats)
PLEASE HELP WILL GIVE BRAINLIEST!!!
Answer:
36
Step-by-step explanation:
We have the summation:
[tex]\displaystyle{\sum_{i=1}^{9} 2i-6[/tex]
Essentially, we want to find the sum of (2i-6) from i=1 to i=9.
First, using summation properties, we can split this to:
[tex]=\displaystyle{\sum_{i=1}^{9} 2i+\displaystyle{\sum_{i=1}^{9} -6[/tex]
On the right, it will simply be -6 evaluated 9 times. We can also move the constant out from the left:
[tex]=\displaystyle{2\sum_{i=1}^{9} i+9(-6)[/tex]
For the summation on the left, this will simply be the sum (1+2+3+...+9). This yields 45. Therefore:
[tex]=2(45)+9(-6)[/tex]
Evaluate:
[tex]=90-54=36[/tex]
So, our final answer is 36.

A food bank sends a truck with 400 pounds of food to each of five local food pantries every week, and receives a government surplus shipment of 3,200 pounds every other week. If it has 10,000 pounds of food on hand at the begining of July , how much will it have six weeks later?
Answer:
6,400
Step-by-step explanation:
The calculation is shown below:-
But before that find the total number of pound in five local bonds
= 400 × 5
= 2,000
Now the amount at six week later is
= Food pounds + 3 × number of pounds + 3 × suplus shipment
= 10,000 + 3 × 2,000 - 3 × 3,200
= 10,000 + 6,000 - 9,600
= 6,400
Therefore according to the given situation the correct answer is 6,400

You get a new job that pays a base salary of $45,000 per year and you earn a commission of $250 per unit sold. How many units would you need to sell to make $90,000 in a year.
Answer:
180
Step-by-step explanation:
subtract 45,000 (the money you already get) from 90,000 and you get 45,000. next divide 45,000 by 250 and get 180 (the amount of units you need to sell in order to make 90k total)

Sylvia buys a case of water that contains 24 bottles and sells x number of bottles to her co-workers. Sam buys a case of water than contains 36 bottles and sells three times as many bottles as Sylvia sold to his co-workers. How many bottles of water did Sylvia sell if they ended up with the same number of bottles of water left over?

Be sure to use the correct place value.
8 points total Show work in order to receive full credit.
7 points correct answer
1 point correct bubbling on grid
Answer:
6
Step-by-step explanation:
Number of water bottles bought by Sylvia = 24
Number of water bottles sold by Sylvia = [tex]x[/tex]
Number of water bottles left with Sylvia = [tex]24-x[/tex]
Number of water bottles bought by Sam = 36
Number of water bottles sold by Sam = Three times as many as bottles as Sylvia sold = [tex]3x[/tex]
Number of water bottles left with Sam = [tex]36-3x[/tex]
It is given that the number of water bottles left with Sylvia and Sam are equal.
i.e.
[tex]24-x=36-3x\\\Rightarrow 2x=12\\\Rightarrow x =\bold{6}[/tex]
So, number of water bottles sold by Sylvia = 6

What is the missing term in the factorization?
12x^2 - 75 = 3( 2x+__ )( 2x - 5 )
Enter your answer in the box.
the missing term is 5
Step-by-step explanation:Hi there !
12x² - 75 =
= 3(4x² - 25)
use formula a² - b² = (a - b)(a + b)
= 3(2x - 5)(2x + 5)
= 3(2x + 5)(2x - 5)
the missing term is 5

In a group of 45 students at a school, all students must study at least one science. Physics is compulsory, but students may also opt to study chemistry or biology or both. 9 students take all three sciences. 24 take both physics and biology (with or without chemistry). 12 students take only physics. How many are studying chemistry and physics but not biology?
Answer:
9 students
Step-by-step explanation:
Let x be the number of students taking only Physics and Chemistry
Number of students :
All 3 sciences = 9
Only physics = 12
Both Physics and Biology( without Chem ) = 24 -9 = 15
15+ 9 + 12+x = 45 , since Physics is compulsory
36 + x = 45
x = 45 - 36
x = 9
