7. Find the theoretical probability P(1, 2, 3, 4, 5, 6).
Answers
Answer:
I have the same questions and I got them right
Step-by-step explanation:
1.) P(2)=4/25
2.) P(4)= 5/25= 1/5
3.) P(2,3)=5/25= 1/5
4/25+1/25= 5/25= 1/5
4.) P(2,4,6)=16/25
4/25+ 5/25+ 7/25= 16/25
5.)There are three even numbers so, 3/6= 1/2. So, 1/2.
6.) P(1, 2, 3, 4, 5, 6)= 25/25 = 1
6/25+ 4/25+ 1/25+ 5/25+ 2/25+ 7/25= 25/25 = 1
P(1)= 6/25 P(2)= 4/25 P(3)= 1/25 P(4)= 5/25 P(5)= 2/25 P(6)= 7/25

Answers
Answer:
x=5
Step-by-step explanation:
isolate the x on one side of the equal sign so move the 2 over by adding 2
4x=x+15 ( add 2 to both sides )
then move the x over
3x=15 ( subtract x from both sides )
then divide by 3
x=5
Answer: Hope it helps, have a nice day :)
x=5
Step-by-step explanation:
So you can only have x on one side, so first you move an x to the other side of the equal sign.
so, 4x-2=x+13, you can move either x, but I'm moving x instead of 4x
-x -x
Your new equation is 3x-2=13, because the x's cancel out
Then you add 2 on both sides 3x-2=13
+2 +2
___________
3x=15
then you divide by 3 on both sides
3x divided by three leaves x by itself, and 15 divided by three is 5.
3x=15
3 3
x=5

Maria deposited $5,700 in an account that earns 8% simple interest. Maria made no withdrawals or deposits. What will be the total amount of money in her account after 6 years?
Answers
Answer:
FV= $8,436
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $5,700
Simple interest (i)= 8% = 0.08
Number of periods (n)= 6 years
To calculate the future value (FV), we need to use the following formula:
FV= PV*i*n + PV
FV= 5,700*0.08*6 + 5,700
FV= $8,436

At 9:00 a.m., the wind speed at Harbor Bay was recorded. After that, the wind speed was recorded every hour. Each measurement showed an increase in wind speed of 3 miles per hour. The strongest wind was recorded at 4:00 p.m., and measured 52 miles per hour. After that, the wind speeds started to decrease. How windy was it when the experiment began?
Answers
Answer:
The wind speed was 31 miles per hour when the experiment began.
Step-by-step explanation:
Linear Dependency
The wind speed is known to increase at a rate of 3 miles per hour every hour.
From 9:00 a.m. to 4:00 p.m. there are 7 hours.
Thus, the speed increased by 7 * 3 = 21 miles per hour during that period of time.
Assuming the wind increased linearly, and its speed was measured at 52 miles per hour at 4:00 p.m., then the initial speed at 9:00 a.m. is calculated by subtracting:
52 miles / hour - 21 miles / hour = 31 miles / hour
The wind speed was 31 miles per hour when the experiment began.
Answer:
The wind speed was 31 miles per hour when the experiment began.

Check for valid triangles
Given 3 sides of a triangle: A triangle is valid If the sum of any two sides is greater than the third
1. Sides: 2cm, 3cm and 4cm
To check:
2cm + 3cm > 4cm --- True
2cm + 4cm > 3cm ---- True
3cm + 4cm > 2cm ----- True
The above conditions are true, hence the input values form a triangle.
2. Sides: 2cm, 3cm and 6cm
To check:
2cm + 3cm > 6cm --- False
2cm + 6cm > 3cm ---- True
3cm + 6cm > 2cm ----- True
One of the above conditions is false. Hence, the input values do not form a triangle.
Given the angles of a triangle, their sum must be equal to 180°
3. Angles: 90°, 45° and 45°
Sum = 90° + 45° + 45°
Sum = 180°
This is a valid triangle because the sum equals 180°
4. Angles: 90°, 60° and 60°
Sum = 90° + 60° + 60°
Sum = 210°
This is not a valid triangle because the sum does not equal to 180°
The above conditions are true, hence the input values form a triangle.
