Answer:
Step-by-step explanation:
Sweet. Get to answer finally. I was the guy commenting on your other post.
1. 72
2. 46
3. 99
4. Same side interior angles are supplementary
5. alternate interior angles are equal to each other so set up the x expressions equal to each other. 5x-7=3x+17. Solve for x
5x-7=3x+17
2x=24
x=12
plug it in for the 5x-7 and get an angle.. 5(12)-7
60-7
53.
The 5x-7 and the 4y+3 is supplementary.
so 53+3+4y=180. combine the 2 and set them equal to 180 to find y
56+4y=180
124=4y
y=31
And now we find the angle of 6. We know that corresponding angles are equal and the y expression and angle 6 are corresponding angles
so plug in your answer for y in the expression..
4(31)+3 = 127.
so angle 6 is 127
6/11(5/6)+2/11(5)
=5/11+10/11
=15/11
Answer:
93% probability of a student taking a calculus class or a statistics class
Step-by-step explanation:
We solve this problem building the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that a student takes a calculus class.
B is the probability that a student takes a statistics class.
We have that:
In which a is the probability that a student takes calculus but not statistics and 
is the probability that a student takes both these classes.
By the same logic, we have that:
The probability of taking a calculus class and a statistics class is 0.07
This means that 
The probability of taking a statistics class is 0.90
This means that 
. So
The probability of a student taking a calculus class is 0.10
This means that 
What is the probability of a student taking a calculus class or a statistics class
93% probability of a student taking a calculus class or a statistics class
Answer:
1st one is 9x-2
2nd is -3x -2
3rd one (put 1 instead of x in the given functions then calculate values and multiple )6
Answer:
1.56%
Step-by-step explanation:
A standard deck of cards has 52 cards, and 13 of these are hearts, as there are 4 suits, and 52/4=13. This means the probability of choosing a heart card from a deck of cards is 1/4, or 25%. Now to find the probability of doing this from 3 decks in a row, we simply cube 1/4 to get 1/64, and in percentage this is ~1.56%.
