A number cube is rolled 120 times. The number 4 comes up 47 times. What is the experimental probability of rolling a 4? What is the theoretical probability of rolling a 4?
Answer:
OPTION B
B. [tex]\frac{47}{120} ; \frac{1}{6}[/tex]
Step-by-step explanation:
A number cube is rolled 120 times; The number 4 comes up 47 times.
First, we have to determine the experimental probability of rolling a 4.
The formula to evaluate probability of an event is given; Probability = [tex]favorable outcomes/totaloutcomes[/tex]
Probability of rolling a 4; the total number of times when 4 appears/the total number of times number cube rolled= [tex]\frac{47}{120}[/tex]
We have to find the theoretical probability of rolling a 4.
Total number of outcomes number cube; 1,2,3,4,5,6
Probability of rolling a 4; [tex]\frac{1}{4}[/tex]
OPTION B IS CORRECT
The changes in depth, in inches, of snow at a ski resort for 4 days are shown below.
−18,−12,34,34
What is the average change in depth of the snow during the 4-day period?
Answer:
Average change = Total change / 4 days
= (7/8) / 4
= 7/32. (C)
Step-by-step explanation:
Average change = Total change / 4 days
Total change = (-1/8) + (3/4) + (3/4) + (-1/2) = 7/8.

The table lists the amount of rainfall in Tucson, Arizona, in the spring months.
A 2-column table with 4 rows titled Rainfall in Tucson, Arizona. Column 1 is labeled Month with entries March, April, May, June. Column 2 is labeled Inches with entries 0.77, 0.36, 0.17, 0.21.
How many more inches of rain did Tucson get in March than it did in June?
0.56
0.60
0.79
0.98
Answer:
0.56
Step-by-step explanation:
0.56 Because you would have yo subtract 0.77 and 0.21
help me pls i need to get up to a 80
Answer:
N=1
Step-by-step explanation:
If N = 1 then 4(1)= 4 whitch is less than 11
But if you plug in any other number
4(4) = 16
4(9) = 36
4(11) = 44
you can see that all of these are greater than 11, but we need something that is less than which would be N=1

Step-by-step explanation:
To find the answer to each, we first need to calculate the circumference:
(use 3.14 for π)
(2 * Diameter) * π = Circumference
Then half the circumference (because it is a semicircle) and add it to the diameter once again to accommodate for the middle line.
(Circumference / 2) + Diameter
Do this for each semi-circle as shown here:
10. (2 * 22) * 3.14 = 138.16
(138.16 / 2) + 22 = 91.08
11. (radius is given so double the middle)
(2 * (2 * 4)) * 3.14 = 50.24
(50.24 / 2) + 16 = 33.12
12. (2 * 10) * 3.14 = 62.8
(62.8 / 2) + 10 = 41.4
Which expression is equivalent to 30 ÷ (3 + x)?
Answer:
I think option G is the correct answer
I think it will help you.
Answer:
G
Step-by-step explanation:
30/(x+3)
it doesn't matter the order of the numbers for addition so the numbers in the parenthesis don't really matter which order they are in.

what is the value of y when: -5=y-7over 9
Answer:
y=-38
Step-by-step explanation:
Undo the things that are being done to the variable.
1: Multiply both sides by nine to undo division.
-45=y-7
2: Add 7 to both side to undo the subtraction.
-38=y
Thats your answer!
Answer:
the answer should be -38 which is option c.
Step-by-step explanation: To get the answer first of all try a number that could be -7 -7 which would be -14 dividing by 9 making the results to be -1.55 or -1.56. So using the same steps trying to find the other answers what is the value of y and if you want use the process of elimination choosing an answer to eliminate and a reason why to eliminate it making it to option c which is the correct answer so sorry if i answer late and please give brainliest to the other people that answer first.

Answer:
Slope: 5/4
Step-by-step explanation:
Answer:
the slope would be 5/4
Step-by-step explanation:
when you count from point (0,-3) where the line perfectly intersects that point, to point (4,2) where it does the same, you end up having to go up 5 lines, and over 4 lines giving you your slope that goes movement on the y-axis over movement on the x-axis or y/x, and you calculate this without diagonals, and you jump before you walk in this case instead of walking before you jump. I do not know what it means by draw a line representing the line, so im sorry on that part.

|120+x| x<-120
Answer:
-120-x
Step-by-step explanation:
Given:
[tex]\displaystyle \large{|120+x| \quad (x < -120)}[/tex]
This is the same as previous one. Recall modulus property:
[tex]\displaystyle \large{|a+x| = \begin{cases} a+x \quad (x \geq -a) \\ -a-x \quad (x < -a) \end{cases}}[/tex]
Keep in mind that |x+a| and |a+x| are equal via addition property.
Since the question gives interval of x < -120:
Therefore, the expression is -120-x

Answer:
#7 = 53.41
#8 = 18.85
#9 = 87. 96
Step-by-step explanation:
The formula for Circumfrance of a circle is: C=2 π r
So lets do #7:
17/2 (the radius is 1/2 of the diameter)
R= 8.5 (now plug in)
C= 2 π 8.5
C=17π
Now repeat on 8 and 9
8:
C= 2 π 3
C=6π
c= 18.85
9:
C= 2 π 14
C= 28π
C= 87.96
