Answer:
x=![\frac{y2 }{9}](https://tex.z-dn.net/?f=%5Cfrac%7By2%20%7D%7B9%7D)
Step-by-step explanation:
2nd step: ![3\sqrt{x}=y](https://tex.z-dn.net/?f=3%5Csqrt%7Bx%7D%3Dy)
third step: ![\frac{3\sqrt{x} }{3} = \frac{y}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5Csqrt%7Bx%7D%20%7D%7B3%7D%20%3D%20%5Cfrac%7By%7D%7B3%7D)
fourth step: ![\sqrt{x} =\frac{y}{3}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20%3D%5Cfrac%7By%7D%7B3%7D)
answer: x=![\frac{y2 }{9}](https://tex.z-dn.net/?f=%5Cfrac%7By2%20%7D%7B9%7D)
Answer:
Changes in size and shape are examples of physical changes in matter
Answer:
a = 70°
b = 80°
Step-by-step explanation:
Angles on a straight line add up to 180°
⇒ a + 110 = 180
⇒ a = 180 - 110
⇒ a = 70°
The sum of the interior angles of a quadrilateral is 360°
⇒ a + b + 130 + 80 = 360
⇒ 70 + b + 130 + 80 = 360
⇒ b + 280 = 360
⇒ b = 360 - 280
⇒ b = 80°
By definition of conditional probability,
P(A | B) = P(A and B) / P(B)
so
P(A and B) = P(A | B) P(B) = 0.5 × 0.58 = 0.29
