A number cube labeled 1 through 6 is rolled once in the spinner shown is spun once. The spinner has four equal sized sections. This experiment is repeated 60 times. The relative frequency for getting a sum of five was 1/5. What is the difference between the number of expected outcomes in the number of actual outcomes?
Answer:
2
Step-by-step explanation:
I did it on Mc Graw Hill
Difference between number of expected outcomes and number of actual outcomes is; 2
What is the number of outcomes?
From the question, we are told that the number cube is labelled from 1 to 6.
This means that there are supposed to be 6 expected outcomes.
However, from the spinner, we see only 4 numbers which are 1, 2, 3 and 4. This means the number of actual outcomes will only be 4.
Thus;
Difference between expected outcome and actual outcome = 6 - 4 = 2

Find 5 Rational Numbers Between 1 and 2 using (a+b/2) where a=1 and b=2.
Answer:
There are two ways to find the rational number between any two numbers. I will tell you an easy method to find it.
As we have to find 5 rational numbers between 1 & 2
Take 5 and add 1 to it i.e. 5+1= 6
Now take the first number and multiply and divide it by 6 i.e.
1x6/6 = 6/6
Also take the second number and multiply and divide it by 6 i.e.
2x6/6= 12/6
This is done to convert 1 & 2 into rational number i.e. in form of p/q
Now we have two numbers 6/6 and 12/6 so five rational numbers between them are
7/6, 8/6, 9/6, 10/6, 11/6
The values of these number you can check will be between 1 & 2. Actually between any two number there are infinite number of rational numbers.

There are 110 calories per 177.4 grams of Cereal X. Find how many calories are in 238.5 grams of this cereal
Answer: 147.87 calories
Step-by-step explanation:
Let the amount of calories in 238.5 grams of this cereal be represented by x.
Based on the information given, we can form an equation as:
110/177.4 = x/238.5
Cross multiply
177.4 × x = 238.5 × 110
x = (238.5 × 110) / 177.4
x = 147.87
Therefore, there are 147.87 calories in 238.5 grams of this cereal.
3. How would you explain to someone who has not yet studied trigonometry the
difference between an identity and an equation?
Answer:
Solving an equation means finding the value or values for which the two expressions are equal. ... An identity is an equation which is always true, no matter what values are substituted.
A trig identity is an equation that is true for all values of x;
For example:
sin²x + cos²x will always equal 1 no matter what the value of x.
There are some equations considered to be identities that are in fact not true all the time.
tan(2x) = 2tanx/(1 - tan²x) is not true when x = π/2 (right side is undefined).
A conditional equation is one that is true for a subset of the real numbers, i.e. for certain values of x, but not all.
For example:
sin²x - 1 = 0 is only true for some values of x.
sin²x = 1
sinx = ±√(1) = ±1
sinx = 1 or sinx = -1
x = sin-11 or x = sin-1(-1)
x = π/2 + 2kπ, k any integer or x = 3π/2 + 2kπ, k any integer (this can be condensed, but left this way for emphasis).

The location of four buildings on a coordinate grid are as follows:
Building 1 is at (−5, −3).
Building 2 is at (−5, 5).
Building 3 is at (4, 5).
Building 4 is at (4, −3).
A bike courier begins at building 1 and then delivers packages to building 2, then building 3, and then building 4. Then she bikes back to building 1. The path between each building is a straight line. One unit on the coordinate grid equals 100 feet.
What is the total distance the courier biked?
Enter your answer in the box.
Answer:
3400 feet
Step-by-step explanation:
Distance between building 1 and building 2 = |5+3| = 8
Distance between building 2 and building 3 = |4+5| = 9
Distance between building 3 and building 4 = |-3-5| = 8
Distance between building 4 and building 1 = |4+5| = 9
total distance = 8 x 2 + 9 x 2 = 34
total distance in feet = 34 x 100 = 3400 feet
Answer: 3400 feet
