Salman flips a fair coin 350 times.
Part A
How many times would you expect Salman to flip heads?
Part B
Was your answer to part a based on theoretical probability or relative frequency?
Explain.
Part C
How many times will Salman flip heads?
A 176
B176
C 165
DbYou really cannot tell for sure
Answers
Answer:
Part A- About 1/2(half) of 350 would be reasonable since there is only two options for all 350 flips.
Part B- Theoretical probability, since an experiment has yet to be conducted it can't be experimental.
Part C- a or b would be a good answer, unless one should be different.

Given line AB, use similar triangles to prove that the slope of line AB is the same between any two points on the line.
1. Create two similar, but not equal, right triangles using segments of line AB as the hypotenuse of each triangle. For the first right triangle use point A(-5,-1) and choose another point on the line to form the hypotenuse. For the second right triangle use point B(4,3.5) and choose another point on the line to form the hypotenuse. For each point used to create the triangles, name the point with a capital letter and coordinates. For example, the triangle using point A could be named ΔACE and the triangle using point B could be named ΔBDF.
2. For the pair of similar triangles created in Part 1, list three pairs of corresponding angles that are equal and three sets of proportionate sides.
3. Use the pair of similar triangles created in Part 1 to demonstrate that the slope of line is the same between any two points on the line.
In your final answer, include a copy of your graph labeling original line AB, and all of Parts 1-3 Be sure to show the vertical and horizontal lengths used for the rise and run of the slope. To submit your answers, use a word processing program or handwritten solutions.

Liz's age is two-thirds of Debbie's age. Debbie's age is half of Freya's age. what is the ratio of Liz's age to Freya's age?
Answers
Answer:
Let's start by using variables to represent the ages of the three people:
Let L be Liz's age.
Let D be Debbie's age.
Let F be Freya's age.
From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:
L = (2/3)D
We also know that Debbie's age is half of Freya's age, so we can write:
D = (1/2)F
To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:
F = 2D
Now we can substitute this expression for F into the equation for Liz's age:
L = (2/3)D = (2/3)(1/2)F = (1/3)F
So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.
How can I find the cube root of 64?
Answers
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.

Tom and Katherine live in different towns which are linked by a bike trail. They agree to meet for a bike ride, and both set off from home at the same time. Tom rides north at a speed of 14 mph and Katherine rides south at 10 mph. The bike trail between their homes is 42 miles long. How long will it be before they meet?
Answers
Answer:
We can start by using the formula:
time = distance / speed
Let t be the time (in hours) for Tom and Katherine to meet.
Tom's distance = Tom's speed x time = 14t
Katherine's distance = Katherine's speed x time = 10t
Since they are riding towards each other, the total distance they cover is the sum of their distances:
Tom's distance + Katherine's distance = 42 miles
14t + 10t = 42
Simplifying:
24t = 42
t = 42 / 24
t = 1.75 hours
Therefore, Tom and Katherine will meet after 1.75 hours of riding.

Answer: A and D are true.
Step-by-step explanation:
Angle 2 is 70.
Find the measures of the other angles.
Step 1: Find angle 1.
As you can see, angle 2 is adjacent (next to) angle 1, and it forms a straight line, so the sum of angles 1 and 2 is 180 degrees.
x+70= 180
x= 180-70
x= 110
Angle 1 is 110 degrees.
Step 2; find angles 3 and 4.
*Vertical angles have the same measure*
as you can see, angle 3 is vertical (right opposite to) angle 1. Therefore, they both have the same length, 110 degrees.
Likewise, angle 2 is vertical to angle 4, and therefore they both measure 70 degrees.
Step 3: Find angles 6 and 5
Angle 6 has the same measure as angle 2 (70 degrees), and angle 5 has the same measure as angle 1 (110 degrees). Also, 5 is vertical to 7 (so they have the same measure), and 6 is also vertical to 8.
This is because whenever a transversal line goes a cross a parallel line, the angles will essentially be duplicates of each other. In other words: A transversal is a line that crosses 2 lines that are parallel to each other, resulting in sets of angles that are alike. You can see that this is true because:
It looks like angles 1 through 4 are in a cluster, and same with 5 through 8. When you look at the X like shape that angles 1 to 4 form is the exact same thing that you see in angles 5 to 8. I hope this was good enough for you to understand
Step 4: Find the true statements:
Angle 1: 110
Angle 2: 70
Angle 3: 110
Angle 4: 70
Angle 5: 110
Angle 6: 70
Angle 7: 110
Angle 8: 70
A. Angle 3= 110 -- True
B. Angle 4= 110 -- False
C. Angle 5= 70 -- False
D. Angle 6= 70 --- This is true

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Answers
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500
