Answer:
32
Step-by-step explanation:
P=2(l+w)
so 2(11+5)=P
2(11+5)=32
answer:
-1
work:
y = mx+ b
so we can tell that the Y intercept is 1, so we can plug that in. ( + b is the y-intercept)
y = mx + 1
plug in some values to find the slope.
(-1, 2)
2 = -m + 1
- 1 - 1
1 = -1m
/-1 /-1
-1 = m
the slope is -1.
i hope this helps! :D
Answer:
$91 is the answer.
Step-by-step explanation:
R = 6%
P = $70
T = 5 year
now
I = PTR/100
=(70×5×6)100
= 2100/100
= $21
So,
I = A-P
21 = A-70
21+70 = A
so, A = $91
The probability that it is pink or canvas is 0.9
Step-by-step explanation:
Let us revise the meaning of "or" , "and" on probability
:
- The use of the word "or" means that you are calculating the probability that either event A or event B happened. Both events do not have to happen
- The use the word "and", means that both event A and B have to happen
The addition rules are:
- P(A or B) = P(A) + P(B) ⇒ mutually exclusive (events cannot happen at the same time)
- P(A or B) = P(A) + P(B) - P(A and B) ⇒ non-mutually exclusive (if they have at least one outcome in common)
Anna is shopping for a new backpack
∵ The probability that the backpack is pink is 0.7
∴ P(pink) = 0.7
∵ The probability that it is canvas is 0.7
∴ P(canvas) = 0.7
∵ The probability that it is pink and canvas is 0.5
∴ P(pink and canvas) = 0.5
Substitute the values above in the rule below
∵ P(pink or canvas) = P(pink) + P(canvas) - P(pink and canvas)
∴ P(pink or canvas) = 0.7 + 0.7 - 0.5
∴ P(pink or canvas) = 0.9
The probability that it is pink or canvas is 0.9
