A number cube is rolled 50 times and the results are shown in the graph below.
Find the experimental probability of rolling a 2
What is a theretical probability of rolling a 2
Find the experimental probability of not rolling a 2
What is the theoretical probability of not rolling a 2
Find the experimental probability of rolling a 1
The experimental and theoretical probabilities for the given experiment are:
i) P = 0.16ii) P = 0.167iii) P = 0.84iv) P = 0.833v) P = 0.2How to get the different probabilities?
i) The experimental probability of rolling a 2 is equal to the quotient between the number of times that the outcome was a 2 and the total number of times that the number cube was rolled, so the probability is:
P = 8/50 = 0.16
ii) The theoretical probability assumes that all the numbers (6) have the same probability of rolling up.
Then all the numbers have a probability of 1/6.
This means that the theoretical probability of rolling a 2 is:
P(2) = 1/6 = 0.167
iii) The experimental probability of NOT rolling a 2 is computed in a similar way than the first one, if out of 50 rolls, in 8 we rolled a 2, then in 42 we did not rolled a 2.
So the probability is:
P = 42/50 = 0.84
iv) The theoretical probability of not rolling a 2 is equal to 1 minus the theoretical probability of rolling a 2.
P = 1 - 1/6 = 5/6 = 0.833...
v) For the experimental probability of getting a 1, we see that out of 50 rolls, in 10 we rolled a 1, so the probability is:
P = 10/50 = 1/5 = 0.2

Write An Equation in Point-slope form for the line through the given point with the given slope "(-7,9);m=4/5"
Answer:
y-9=4/5(x+7)
Step-by-step explanation:
Point slope for is y-y1=m(x-x1). In this case, y1 is 9, x1 is -7, and m is 4/5. Therefore, we can fill in this equation. The equation will be y-9=4/5(x--7) This is equal to y-9=4/5(x+7).

Step-by-step explanation:
The triangles satisfy the Converse Hi nge Theorem Condition the two triangles have two corresponding equal sides. Thus, the included angle of the triangle that has the largest length of the third side is greater than the included angle of the other triangle with a lesser third side length.
Thus,
33 > 3x - 3
Solve for x
33 + 3 > 3x - 3 + 3
36 > 3x
36/3 > 3x/3
12 > x
To ensure the angle is not 0 or negative, thus:
3x - 3 > 0
Solve for x
3x - 3 + 3 > 0 + 3
3x > 3
3x/3 > 3/3
x > 1
Possible range of values of x would be:
1 < x < 12

The telephone company offers two types of service. With Plan A, you can make an unlimited number of local calls per month for $18.50. With Plan B, you pay $6.50 monthly, plus 10 cents for each min. Of calls after the first 40 min. At least how many min would you have to use the telephone each month to make Plan A the better option?
Answer:
This is telling me that plan B is the better choice
for a certain number of minutes, but after that,
plan A is better.
Let +n+ = number of minutes of calls
with plan B
-----------------------------------------
Set up an equation that makes the 2 plans equal
and then add 1 more minutes to +n+
-----------------------------------------
plan A = plan B
+18.5+=+6.5+%2B+.1%2A%28+n+-+40+%29+
Step-by-step explanation:
Answer:
Plan A is better if you talk at least 121 minutes per month
Step-by-step explanation:
1. Plan B is $6.50 plus 10 cents for each minute
2. Plan A is $18.50
3. For plan A to be better, one need to spend over $12 extra
4. Each minute cost 10 cents, so $12 would be 120 minutes of talk
5. Plan A is better if you talk at least 121 minutes

All four-sided figures are parallelograms true or false
pls explain why
Answer:
True
Step-by-step explanation:
Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides. Parallelograms are quadrilaterals with two sets of parallel sides. Since squares must be quadrilaterals with two sets of parallel sides, then all squares are parallelograms.
A rectangle has all the properties of a parallelogram, plus the following: The diagonals are congruent.
Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides.
Parallelograms are quadrilaterals with two sets of parallel sides. Since squares must be quadrilaterals with two sets of parallel sides, then all squares are parallelograms. This is always true. (actually is true)
Between 06 00 and 10 00,the same day ,the volume of water in a reservoir decreased from 24 000L to 18 000L.What was the average rate of decrease in volume of water, giving your answer in L/h?
Answer:
-1.5 L/h
Step-by-step explanation:
The volume of water in a reservoir decreased from 24.000L to 18.000L between 06.00 and 10.00.
We need to find the average rate of decrease in volume of water. It can be solved as follows :
[tex]Rate=\dfrac{18-24}{10-6}\\\\=-1.5\ L/h[/tex]
The negative sign shows the decrease in volume. Hence, the rate of decrease in volume of water is 1.5 L/h.

Here's a visual way to see what's going on. Start by drawing a rectangle of any size or shape. Cut the rectangle vertically into 10 equal slices. Then shade 9 of those slices to represent the fraction 9/10, which is how far (in miles) Lewis walked. See the diagram below. Specifically, refer to figure 1.
The friend walked 2/5 of this shaded amount. Draw 4 horizontal lines to split each vertical bar into 5 equal pieces. So we'll be forming a grid of smaller rectangles. For any given column, you'll shade exactly 2 smaller rectangles out of the 5 total. Hence the 2/5. This is shown in yellow in figure 2. The yellow region is 2 units tall by 9 units across, so we have 2*9 = 18 yellow rectangles in all. This is out of 5*10 = 50 smaller rectangles overall.
That's how we get to the fraction 18/50 which reduces to 9/25 when you divide both parts by the GCF 2.

volume of triangular prism
Answer:
48 cm^2
Step-by-step explanation:
The area of one of the triangular ends is A = (1/2)(4 cm)(3 cm) = 6 cm^2.
Multiply this "base area" by 8 cm, the length of the prism. We get:
volume of triangular prism = (6 cm^2)(8 cm) = 48 cm^2
