Step-by-step explanation:
(x+y+2)(y+1)
Opening the brackets
xy + x + y^2 + y +2y +2
y^2 +xy + 3y + x +2
Answer:
m∠P = 143°
Step-by-step explanation:
We know that supplementary angles add up to 180, and with the knowledge that angle P is 5 times than 4 less (5x-4) the measure of angle Q (x), we can set up the equation (4x-5)+(x)=180. We can then solve and get x = 37, and then we can plug X back into 5x-4 to get the angle of 143 degrees.
Answer:
0.4 = 40% probability that a toy that Raymond picks out of a box is plush given that it is a dinosaur.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Dinosaur
Event B: Plush.
The probability that a toy Raymond picks out of a box is a dinosaur is 75%.
This means that
The probability that a toy Raymond picks out of a box is both plush and a dinosaur is 30%.
This means that
What is the probability that a toy that Raymond picks out of a box is plush given that it is a dinosaur?
0.4 = 40% probability that a toy that Raymond picks out of a box is plush given that it is a dinosaur.
Answer:
36.695 approx 36.7
Step-by-step explanation:
find the area of the top triangle and then add it to the area of the bottom rectangle
Area of the triangle: (bh)/2
3.5*4.1=14.35
14.35/2=7.175
Area of the rectangle: bh
4.1*7.2=29.52
Total (add the two values)
29.52+7.175
=36.695
