Answer:
60 times.
Step-by-step explanation:
Prob( of rolling a 2) = 1/6
Prob( of rolling a 3) = 1/6
So Prob( 2 or 3) = 1/6 + 1/6 = 1/3,
So the prediction is 1/3 * 180 = 60.

A student is working on a project for which he records the revolutions per minute (rpm) for a small electric motor as he increases the voltage in a circuit. Here is the table showing the results:
Voltage
(volt) Motor Speed
(rpm)
0 0
1 25
2 50
3 75
4 100
Create a graph showing the relationship in the table. Think about the title, axis labels, and whether you need to connect the points with a line.
Answer:
See below ↓
Step-by-step explanation:
The relation is :
Let y = Motor Speed and x = Voltagey = 25xTitle : Variation of Motor Speed with Applied Voltage
x-axis label : Voltage (volt)
y-axis label : Motor speed (rpm)
As it constantly varies with a value of x and they are not isolated data points, they should be connected with a line.
Here are the first four terms of a sequence: 3, 12, 48 and 192.
(a) Work out the common ratio for this sequence.
(b) Work out the nth term of this sequence.
Answer:
look below
Step-by-step explanation:
The common ratio is 1:4 because we are multiplying the previous number by 4
The nth term for this sequence is quite simple. To find the nth term, take the base, 3, and multiply by the nth 4th. This can be written as 3*4^n+1
I hope this helped!
It would be greatly appreciated if you marked this answer as brainliest!
Answer:
see explanation
Step-by-step explanation:
the sequence is geometric and has common ratio r
(a)
r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{12}{3}[/tex] = 4
(b)
the nth term of a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]
where a₁ is the first term and r the common ratio
here a₁ = 3 and r = 4 , then
[tex]a_{n}[/tex] = 3 . [tex]4^{n-1}[/tex]

Use the distributive property to simplify 3(4x+8).
a) 7x + 8
b) 7x + 24
c) 12x + 8
d) 12x + 24
Answer:
d) 12x + 24.
Step-by-step explanation:
3(4x+8)
= 3*4x + 3*8
= 12x + 24.
The Distributive Property states the following:-
[tex]\bigstar{\boxed{a(b+c)=ab+ac}}[/tex]
So we distribute a by multiplying it times b & c.
Now, let's simplify the given expression:-
[tex]\bigstar{\boxed{3(4x+8)=12x+24}}[/tex]
Hence, Option D) is correct!
note:-Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)

In which [tex]a_1[/tex] is the first term.
In this problem, we have that:

Step-by-step explanation:
How do I find the length of K?
Answer:
i) 3.7 cm
ii) 3.0 cm
Step-by-step explanation:
When you are given side lengths and angle measures, trig functions will generally be involved in solving the triangle. The mnemonic SOH CAH TOA is intended to remind you of the trig relations pertaining to a right triangle.
__
i)The sides adjacent to the angle and opposite the angle are given. The relevant relation is ...
Tan = Opposite/Adjacent
tan(63°) = k/(1.9 cm)
k = (1.9 cm)tan(63°) ≈ 3.7 cm
The length k is about 3.7 cm.
__
ii)Again, the tangent function can be used to solve this triangle.
tan(42°) = (2.7 cm)/p
p = (2.7 cm)/tan(42°) ≈ 3.0 cm
The length p is about 3.0 cm.

Step-by-step explanation:
This question is NOT statistical because it has a definite answer.
There is one number that can represent how many pets are owned by let's say your uncle.

9 - 6 = 38. A cube container, with original volume 64 in. 3, is being redesigned to increase
its capacity. The expression x + 64 in. ? models the volume of the new cube.
If the volume can increase by a maximum of 100 in. 3, what is the maximum
measurement of the edge of the larger cube, rounded to the nearest tenth?
The volume of the cube container is the amount of space in it, and the maximum measurement of the edge of the larger cube is 5.5 inches
How to determine the maximum edge of the larger cube?The volume of the container is given as:
V = 64 cubic inches
When it increases by a maximum of 100 cubic inches, the new volume becomes
V = 164 cubic inches
The volume of a cube container is calculated using:
V = l³
Where l represents the edge length of the cube
Substitute 164 for V
l³ = 164
Take the cube root of both sides
l = 5.5
Hence, the maximum measurement of the edge of the larger cube is 5.5 inches

in a sale, the price of a computer is reduced by 20%. At this reduced price the shopkeeper still makes a profit of 20%. What would have been his percentage profit if the computer had been sold at full price?
Based on the price the computer was reduced by and the profit the shopkeeper still made, if the computer was sold at full price, the profit percentage would have been 50%.
What would the profit have been at full price?First assume a price the computer was sold at. We'll go with $100.
At this price, the shopkeeper still made a profit of 20% which means that the cost price was;
= 100 / (1 + 20%)
= $83.33
Based on the discounted price of $100, the full price was:
= 100 / (1 - 20%)
= $125
The profit the shopkeeper would have made is:
= (Full price - Cost price) / Cost price x 100%
= (125 - 83.33) / 83.33 x 100%
= 50%

Answer:
Mode: 7
Range: 6
Step-by-step explanation:
Think of the M and O in "mode" as "most often." The mode is the number that appears more than any other.
Range is the difference (subtraction) between the smallest number and largest number in the data. So we have 3, 5, 5, 7, 7, 7, 7, 7, 8, 8, and 9. We take the largest number, 9, and subtract the smallest number, 3, from it.
9-3 = 6
In the future, if you come across "median," that means to put all of the numbers in order from least to greatest and whatever number is in the middle will be the median. Think of the median of a road, which is at the center. The median in this data set would be 7. If you have two different numbers in the center, find the number between those two. For example: if the two median numbers were 7 and 8, the median would be 7.5.
The mean is the sum of all of the numbers, divided by two. So for this data set, you would do 3+5+5+7+7+7+7+7+8+8+9. Then, you would take the total and divide it by 2.
73 / 2 = 36.5
