you roll a standard number cube 180 times. predict how many times you will roll a 2 or a 3

Answers

Answer 1

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.

What is the common difference of the arithmetic
sequence?


Answers

Using arithmetic sequence concepts, it is found that the common difference is of 0.25.

What is an arithmetic sequence?

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of an arithmetic sequence is given by:

[tex]a_n = a_1 + (n - 1)d[/tex]

In which [tex]a_1[/tex] is the first term.

In this problem, we have that:

[tex]a_3 = 8, a_7 = 9[/tex]

Hence:

[tex]a_7 = a_3 + (7 - 3)d[/tex]

9 = 8 + 4d

4d = 1.

d = 0.25.

The common difference is of 0.25.

How do I find the length of K?

Answers

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.

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?

Answers

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%

8. 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?

Answers

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

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.
