Why is the table not a probability distribution table?

Mathematics
1 answer:
jeyben [28]2 years ago
8 0

Using <u>probability distribution concepts</u>, the correct option is:

  • C. the sum of the probabilities is not 1.00

  • In a probability distribution, the <u>sum of all probabilities has to be equals to 1</u>.

In this problem, the probabilities are: 0.25, 0.45, 0, 0.35.

Their sum is:

0.25 + 0.45 + 0 + 0.35 = 1.05

Since the <u>sum is not 1</u>, the correct option is:

  • C. the sum of the probabilities is not 1.00

The product of 2 consecutive #s is 4160 what are the numbers?
KengaRu [80]
So the so the product of two consecutive numbers is 4160 or
x(x+1)=4160
distribute
x^2+x=4160
subtract 4160 from both sides
x^2+x-4160=0
find the factor (if you want to know how, just ask in the comments)
(x-64)(x+65)=0
so the answer is x could be 64 or -65
so the number that work are 64,65 and -65,-64

Rounded to the nearest hundredth, what is the positive solution to the quadratic equation 0 = 2x2 + 3x – 8?
zmey [24]
2x² + 3x -8 = 0

a = 2 , b = 3 , c = -8
So..
D = b²-4ac = 9 + 64 = 73

for bigger solution , use x = -b + √D / 2a
For smaller solution, use x = -b - √D / 2a

So
= -3 + √73 / 2. 2
= 1/4 (√73 -3)

Hopefully helpfull.. ^_^

 A movie theater sends out a coupon for 85​% off the price of a ticket. Write an equation for the​ situation, where y is the pri
ra1l [238]

Answer:

y=0.15x

Step-by-step explanation:

Given:

Original price of the ticket is x

Price after using the coupon is y

Coupon discount is 85% of x=0.85x

Therefore, the price after applying coupon is given as the difference of the original price and the coupon discount. That is,

y=x-0.85x=x(1-0.85)=0.15x\\\therefore y=0.15x

The graph is shown below. The graph passes through the origin as the above relationship is a proportional relationship.

The line y=0.15x strictly remains in the first quadrant as both x and y can't be negative as they represent price of tickets and price can never have negative values. Hence, only the first quadrant has both the values of x and y positive.
