There are black, blue, and white marbles in a bag. The probability of choosing a black marble is 0.36. The probability of choosi
Gala2k [10]

Answer: c) 0.75

Step-by-step explanation:

Given : The probability of choosing a black marble is P(Black)= 0.36.

The probability of choosing a black and then a white marble is P( Black and white) = 0.27.

Then by conditional probability ,

The probability of the second marble being white if the first marble chosen is black = P(\text{white }|\text{Black})=\dfrac{\text{P( Black and white)}}{\text{P(Black}}

=\dfrac{0.27}{0.36}=\dfrac{27}{36}=0.75

Therefore , the probability of the second marble being white if the first marble chosen is black = 0.75

What is the difference in Fahrenheit degrees between a temperature of 0C and a temperature of 15C?
slamgirl [31]

Answer:

27^{\circ}F

Step-by-step explanation:

Use formula

F=1.8C+32

to convert Celsius to Fahrenheit.

When C_1=0^{\circ}C, then

F_1=1.8\cdot 0+32\\ \\F_1=32^{\circ}F

When C_2=15^{\circ}C, then

F_2=1.8\cdot 15+32\\ \\F_2=27+32=59^{\circ}F

Difference:

F_2-F_1=59^{\circ}F-32^{\circ}F=27^{\circ}F

Find the derivative of the function.. y = cot2(sin θ).
lana66690 [7]
Y = cot2(sinФ)
dy/dФ = d/dФcot2(sinФ)
 dy/dФ = -cosec²2(sinФ) d/dФ2(sinФ)
dy/dФ = -cosec²2(sinФ) 2cosФ
dy/dФ =-2[cosФ][cosec²2(sinФ)]
