Answer:
B
Step-by-step explanation:
540 is the sum of all angles in a pentagon
The ANGLE STP is 180-50 = 130
540 - 130 is 410
The probability of getting grey: 2/10
The probability of getting blue: 8/10
The probability of getting blue then grey:
8/10 x 2/10
Answer 4/5
Answer:
13/52 (0.25) (25%)
Explanation:
There are 52 cards in a standard deck and there are four suits.
52/4 = 13
So, the probability (assuming that’s what you are asking for) is a 13/52 chance you will pull a hearts card.
Box and whiskers plots use five number summaries. The first number is:
1:Minimum
2.Quartile 1
3.Mean
4.Quartile 2
5.maximum
Quartile are simple to get.
If your set of numbers is:
2,3,3,6,8,8,11
Then find the mean
2 3 3 |6| 8 8 11
Find the mean of the left side of of mean.
2 |3| 3 3 =Quartile 1
Then the right side
8 |8| 11 8 =Quartile 2
-----------------------------------------------
Your 5 number summary is 2,3,6,8,11
Plot them on the number line, but put a line above where the dot would go. take the 3 middle lines and connect to make a box. The lines on the outside of the box are the whiskers, AKA distributed data.
Y = 3x + 7....slope is 3, y int is 7
y = 3x + 2...slope is 3, y int is 2
when the slopes are the same, but the y intercepts different, then it is a parallel line with no solutions.
little tip :
slopes same, y int different, = no solution
slopes same, y int same = infinite solutions
slopes different, y int different = 1 solution
