Answer:
The game’s expected value of points earned for a turn is 71.
Step-by-step explanation:
Here we know that:
Points Frequency
50 55
75 32
150 13
Here points earned is a random variable.
We need to find its expected value,
Finding Expected value:
Expected value of a random variable is its mean value. So we will first find the mean value of points earned per turn from the table we are given.
Total number of turns = sum of frequencies
= 55 + 32 + 14 = 100
Total points earned = 50(55) + 75(32) + 150(13)
= 7100
Expected value of points earned for a turn = Mean value of points
= Total points/no. of turns
= 7100/100
= 71
Yes, a triangle can be formed using those side lengths. This is because when using Triangle Inequality Theorem, any two side lengths added together is greater than the third side. The triangle is also scalene since none of the sides have the same measure.
9)To find the LCD you need to find a number that all of the denominator numbers can divide into, for this problem it would be 12. 12/6+12/4+12/3=1
2+3+4=1
9=1
No solution
10) In order to solve this problem you need to cross multiply
2(3x+5)=7(10
6x+10=70
6x=60
x=10
Have a great day!:)
Answer:
Your answer would be C, Sin A= 3/5 cos A= 4/5
Step-by-step explanation:
Remember Soh-cah-toa
Soh stands for sin= opposite/hypotenuse
Cah stands for cos= adjacent/hypotenuse
Toa stands for tan= opposite/adjacent
