Dina has a number cube that she uses for a game.
The number cube has the shape of a triangular pyramid, with 4 faces numbered 1 through 4. Dina rolls the number cube 100 times and records the results. She calculates the relative frequency of each outcome.
Outcome 1 2 3 4
Relative Frequency 0.23 0.24 0.26 0.27
Which statements about Dina's experiment are true?
Select each correct answer.
The relative frequencies in the table are reasonably close.
The theoretical probability of rolling an even number is 0.51.
The relative frequency of rolling an even number is 0.51.
The number cube is not likely to be fair.
Answers
Answer: the relative frequencies in the table are reasonably close.
Step-by-step explanation:
Theoretically relative frequency for all numbers are 0.25. If cube is cast
100 times there my be small fluctuations.
An unknown number y is 10 more than an unknown number x. The number y is also x less than 3. The equations to find x and y are shown below. y = x + 10 y = −x + 3 Which of the following statements is a correct step to find x and y? (4 points) a Add the equations to eliminate x. b Multiply the equations to eliminate y. c Write the points where the graphs of the equations intersect the x-axis. d Write the points where the graphs of the equations intersect the y-axis.
Answers
Answer:
Answer (a)
Step-by-step explanation:
y = x + 10
y = −x + 3 It's easier to see what to do next if you first write these equations in a column.
Combining these equations, we get 2y = 13, so that y = 13/2.
Answer (a) is the best choice of the four possible answers.

Facts:
Justin jogs 3 2/3 miles every morning
Jogs 4 6/10 miles every evening.
Miles jogged per day=?
To solve this question,add the 2 fractions.This makes sense because let's say you ran 3 miles in the morning and 2 miles in the evening, nothing more nothing less, and you wanted to find how much you ran in a day, you'd add these 2 nummbers.
3 2/3 + 4 6/10
Step 1: Add the whole numbers
3 2/3 + 4 6/10
3+4= 7
7 + 2/3 + 6/10
Step 2: Find a common denominator between 10 and 3
10x1= 10
10x2= 20
10x3= 30 (works for both 3 and 10)
7 + __ + __
30 30
Step 3: Change the neumerators
Now when adding fractions this way, you have to multiply and change the neumerator:
In the 1st fraction, the original denominator was 3. And 3x10= 30, right? So you must also multiply the neumerator by 10 so that they are equivalent to each other
2x10= 20
In fraction #2, the neumerator was 6. 6x3= 18
7 + 20 + 18
30 30
7+38/30= 7 38/30= 8 8/30 miles per day

Last year, the tree was 5 11/12 feet long.
This year, the tree is 7 2/3 feet long.
How many feet did it grow?
Convert to decimals and subtract:
7 2/3= 7.66667
5 11/12= 5.9166667
7.66667- 5.916667= about 1.75, which becomes 1 3/4

A new store is handing out small gifts to the customers who come in. Elizabeth is handing out pens of various colors.She has determined that the chance of a customer receiving a blue pen is 0.008. Ricardo is handing out tote bags of various colors. He has determined that the chance of a customer receiving a blue tote bag is 0.04. What statement describes the likelihood of a customer getting a blue tote bag or a blue pen?
It is very unlikely that a customer gets a blue tote bag, but it is very likely that a customer gets a blue pen.
It is very unlikely that a customer gets a blue tote bag, and it is very unlikely that a customer gets a blue pen.

Answer:

Step-by-step explanation:

It is very unlikely that a customer gets a blue tote bag, and it is very unlikely that a customer gets a blue pen (Option B)
How can we interpret probability?Probability of an event is a measurement of how likely an event can occur as an outcome of a random experiment.
Probability ranges from 0 to 1, both inclusive. Events whose probability is closer to 0 are rarer to occur than those whose probabilities are closer to 1 (relatively).
Since it is given that:
The chance of a customer receiving a blue pen = 0.008The chance of a customer receiving a blue tote bag = 0.04Both probabilities are too close to 0, than 1. So they both are very unlikely to occur.
Thus, it is very unlikely that a customer gets a blue tote bag, and it is very unlikely that a customer gets a blue pen (Option B).

The probability of landing on tales is 1/2 as shown in the right section.
Becuase it is an or and not an and... you have to add them together.

A block of iron has dimensions of 1 cm x 2 cm x 5 cm and has a
mass of 799
What is its density? (V=lxwxh)
Answers
Answer:
79.9 units
Step-by-step explanation:
Hi there,
Before solving this problem, it is important to know the formula:
D = [tex]\frac{m}{v}[/tex].
D = density
m = mass
v = volume
Since we are given the mass and volume, we can simply enter these values into the formula to find the density of the block.
D = [tex]\frac{799}{10}[/tex]
D = 79.9
Therefore, the density of the block of iron is 79.9 units. I wrote units since you did not specify the unit for the mass. Hope this answer and explanation helps.
Cheers.
