Answer:
C
Step-by-step explanation:
The tricky part is always what is in the brackets with the x. It is highly anti intuitive.
(x + 2) moves the graph left, not right as you might think. So from this, only C and D can be considered as answers.
Since the 2 is with the x, that's how many units left you will go -- 2 units.
C is the only possible answer.
The - 7 tells you it will move 7 units down. The 7 with a minus acts the way you think it should. It goes down which is what normally happens on a graph. A mnus number outside the brackets means down.
Answer:
P=0.833
Step-by-step explanation:
The die is six sided so (1,2,3,4,5,6)
Even numbers (2,4,6) P(even)=3/6
Less than 5 (1,2,3,4) P(<5)=4/6
A ∩ B= (2,4) P(A ∩ B)=2/6
The formula to calculate the “or” probability of two events A and B is this: P(even)+P(<5)-P(A ∩ B)
3/6+4/6-2/6=5/6
Answer:
She can attend 6 Yoga classes.
Step-by-step explanation:
150 ÷ 13 is about 11.Then multiply 11x 13 and that equals 143. Then you subtract 65 from 143 and you get 78. Then 78 divided by 13 equals 6.
Answer:
Step-by-step explanation:
we have the mean=13
(x+y+z)/3=13
x+y+z=39
range=highest value-lowest value=10
lets say x= highest value
y=lowest value
x-y=10
x=10+y
the numbers are 9,11,19
19-9=10 range
sum is 39
