Answer:
Option B.
Step-by-step explanation:
Continuous probability distribution : A probability distribution is called a continuous probability distribution, if its random variable X is a continuous variable and it can take infinite values (Real values).
Number of boxes cannot be a decimal value. So, it is not a continuous variable. Thus, option A is incorrect.
Temperature of a day is a continuous variable. So, temperature of a day can be represented using a continuous probability distribution. So, option B is correct.
Marks in a test paper cannot represent a continuous variable. Thus, option C is incorrect.
Number of students who uses the internet cannot be a fractional or decimal value. So, it is not a continuous variable. Thus, option D is incorrect.
Therefore, the correct option is B.

The other choices are not true statements, while -4 is less than -8
Answer:
This is really weird. None of them seem to be right.
For the first one, it says that -7.5 is greater than or equal to -6.4, which is not true. -7.5 is less than -6.4. The next one is the only one that makes a true comparison, but I don't agree with the "or equal to" part. -7/8 cannot be equal to 7/8. The next one is false, -4 is greater than -8. Finally, the last one is incorrect as well because -4.2 is less than -3.6.
However, if I had to choose one, I'd choose the second option. It's the closest to being correct.

A sporting goods store receives a shipment of 124 golf bags. The shipment includes two types of bags, full-size and collapsible. The full-size bags cost $38.50 each. The collapsible bags cost $22.50 each. The bill for the shipment was $3430. How much of each type of golf bag should be in the shipment? Show all work and verify your answer (prove that your answer is correct)
Answers
The sporting goods store receives the shipment of 124 golf bags in total.
Let us assume that the number of full-sized bags = X
Then the number of collapsible golf bags = 124 - X
Cost of each full sized bags = $38.50
Cost of each collapsible bags = $22.50
Total cost of the 124 bags received by the sporting goods store = $3430
Then
(38.50)X + (124 - X)22.50 = 3430
(38.50X - 22.50X) + 2790 = 3430
16X = 3430 - 2790
16X = 640
X = 640/16
= 40
So the number of full-sized golf bags received = 40
Then the number of collapsible golf bags received = 124 - 40
= 84

d=76.157t is the expression for two vehicles, a car and a truck which were distance apart d (in miles) at the end of t hours.
Two vehicles, a car and a truck, leave an intersection at the same time. The car heads east at an average speed of 70 miles per hour, while the truck heads south at an average speed of 30 miles per hour. we need to find expression for their distance apart d at the end of t hours
What is distance?Distance=Speed*Time
distance= speed * time.
*70t be the car traveling EAST at 60 miles per hour after t hours
*30t be the distance of the truck traveling SOUTH at 20 miles per hour after t hours.
*Use the Pythagorean Theorem to find the distance d.
The Pythagoras theorem states that sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse
d^2=(70t)^2+(30t)^2
d^2=4900t^2+900t^2
d^2=5800t^2
d=76.157t
Therefore d=76.157t is the required expression for their distance apart d (in miles) at the end of t hours.

What happens to the value of the expression \dfrac{3y}{2y} 2y 3y start fraction, 3, y, divided by, 2, y, end fraction as yyy increases?
Answers
Answer:
The value of expression remains the same
Step-by-step explanation:
Let the given function be f(y), where
[tex]f(y) = \frac{3y}{2y}[/tex]
Lets put different values of y to finds its effect on the function
f(y) = 3y/2y
Let y = 1
f(1) = 3(1)/2(1) = 3/2
Let y = 2
f(2) = 3(2)/2(2) = 6/4 = 3/2
Let y = 3
f(3) = 3(3)/2(3) = 9/6 = 3/2
Let y = 10
f(4) = 3(10)/2(10) = 30/20 = 3/2
As we can see, no matter whatever value of y we put in the expression, the result is always the same i,e 3/2
Hence,
The value of expression remains the same

There are 36 total possible outcomes.
Rolling a sum of 11 or higher, there are 3 possible rolls, to make a 3/36 = 1/12 probability.
Rolling a sum of 4 there are also 3 possibilities, so the chance would be the same.
Rolling a sum of 9, there are 4 possibilities, which is a better chance.
Rolling a sum less than 5, there is 6 possibilities, which is a better chance.
Rolling greater than 5 but less than 7 means rolling a sum of 6, there are 5 chances, which is a better chance.
Rolling greater than 9 but less than 11, means rolling a 10, there are 3 possibilities, which is the same.
Rolling greater than 2 and less than 4 means rolling a 3, there are 2 possibilities, which is less.

subract 5 5/21 from 13 1/7
Answers
Answer:
The answer is 166/21, or 7 19/21
Step-by-step explanation:
First, you would set up the equation, which is:
13 1/7 - 5 5/21
Next, you would turn them into an improper fraction, which is:
92/7 - 110/21
Then, you would multiply 92/7 by 3/3 because that is the least common multiple for 21 and 7 (which are the denominators). When you are done multiplying, the equation would be:
276/21 - 110/21
Afterwards, you would subtract the numerators and leave the denominators alone, which gives you the answer 166/21. As a mixed number, this would equal 7 19/21.
Answer:
7 19/21
Step-by-step explanation:
13 1/7 - 5 5/21
Get a common denominator
13 1/7*3/3 - 5 5/21
13 3/21 - 5 5/21
We need to borrow 1 from the 13 in the form of 21/21
12 +21/21 + 3/21 - 5 5/21
12 24/21 - 5 5/21

Multiply each side by 3
(x-2)^2/3 *3=9*3
(x-2)^2=27
Take the square root of each side
sqrt( (x-2)^2)=±sqrt(27)
x-2 = ±3sqrt(3)
Add 2 to each side
x = 2±3sqrt(3)

Answers
Answer:
x = 114°
y = 27
Step-by-step explanation:
To get x, we simply subtract 66° from 180°. Because of same-side interior angles, the angle below x is 66°.
To find y, we set the expression equal to 66° because they are the same angle. When we solve for y, we get 27.
Answer:
x= 114,
y= 27
Step-by-step explanation:
x= 180 - 66 = 114
6y - 96 = 66, 6y= 66+96, 6y= 162, y= 162/6, y= 27

Answers
Answer:
x = 2
y = 1
z = 3
Step-by-step explanation:
Okay, we know y=z-x.
Let's plug in that y-value into the first equation: x + 2 (z - x) -z =1
Simplify that down to x +2z -2x -z = 1
Equation 1 becomes -x + z = 1
Let's plug it into equation 3 and solve to get: 2x - (z - x) +3z = 12
Equation 3 becomes 3x + 2z = 12
Now let's use system of equations for those two equations we just found
3x + 2z = 12
-2x + 2z = 2 ------> multiplied this by 2 to simplify
subtract, and you 5x = 10, x = 2
Use x = 2 and solve for the other variables using the same method (try this on your own!) to get y = 1 and z = 3
Solve for y. Please show work.

Answers
Answer:

Step-by-step explanation:
5y^2 - 2 = 3y
5y^2 - 3y - 2 = 0
(5y + 2)(y - 1)
5y + 2 = 0 or y - 1 = 0
5y = -2 or y = 1
y = -2/5 or y = 1
Answer:
y = -2/5 or y = 1
Step-by-step explanation:
5y²-2 = 3y
Add -3y on both sides
5y²- 3y -2 = 0
Factorize.
(5y + 2)(y-1) = 0
(5y+2) = 0
Subtract 2 on both sides.
5y = -2
Divide 5 into both sides.
y = -2/5
(y - 1) = 0
Add 1 on both sides.
y = 1
