Answer:
A. 1/2.
B. 15/26.
Step-by-step explanation:
Note when you have an 'OR' in the statement we <u>add </u>the probabilities.
A . Club or a diamond . There are 13 clubs and 13 diamonds so
The Required Probability = 13/52 + 13/52
= 1/4 + 1/4 = 1/2.
B. There are 4 jacks and 26 black cards.
The Required Probability = 4/52 + 26/52
= 1/13 + 1/2
= 2/26 + 13/26
= 15/26.
Answer:
Option 4 is correct. The length of PR is 6.4 units.
Step-by-step explanation:
From the given figure it is noticed that the triangle PQR and triangle MQR.
Let the length of PR be x.
Pythagoras formula
Use pythagoras formula for triangle PQM.
The value of PM is 10. The length of PR is x, so the length of MR is (10-x).
Use pythagoras formula for triangle PQR.
.....(1)
Use pythagoras formula for triangle MQR.
.... (2)
From equation (1) and (2) we get
Therefore length of PR is 6.4 units and option 4 is correct.
Answer:f(x)=x^(2)-4x-1
Step-by-step explanation: Ezzz
Sadly, you didn't put any sums on your list of choices.
In fact, I can't even find a list of choices !
To find the distance between (7, -1) and (-8, -9),
you would build a sum under a square-root (radical)
symbol, and it would look something like this:
√ ( 225 + 64 ) .
Answer: y = 3x - 6
Step-by-step explanation: A line that is parallel to another line must have the same slope, so you already have y = 3x + b. To find b, use the point that they give. b is the y-intercept, so just subtract 3(x) from the y coordinate of the point, where x is the x-coordinate of the given point.
