Answer:

1/36

Step-by-step explanation:

P( red die is 6) = number of 6/ total = 1/6

P( green die is 6) = number of 6/ total = 1/6

P( red is 6 and green is 6) = P( red die is 6) *P( green die is 6)

=1/6*1/6

=1/36

devlian [24]

Answer:

A = 3W² + W + 1/8πW²

Step-by-step explanation:

rectangular window is L x W

semicircle is 1/2 πr²

r = 1/2 W

L = 3W + 1

A = W(3W + 1) + 1/2 π(1/2W)²

A = 3W² + W + 1/8πW²

(-5,7) and (2,5) <br> find the slope of the line passing through the given points

svp [43]

Answer: -2/7

Step-by-step explanation:

To find the slope, you use the formula $m=\frac{y_2-y_1}{x_2-x_1}$ .

$m=\frac{5-7}{2-(-5)} =\frac{-2}{7}=-\frac{2}{7}$

Now, we know the slope is -2/7.

What is the experimental and theoretical probability?

natka813 [3]

I believe ( i am not 100% certain) that the theoretical probability would be 1/2 or 300/600 and the experimental probability is 252/600, you may need to simplify that

A spinner has 10 10 equal-sized sections. Six Six of the sections are purple purple. a. What is the probability that the spinne

borishaifa [10]

Answer:

P(Spinner lands on purple section) = 0.6 = 60%

Step-by-step explanation:

We are given the following in the question:

Number of sections = 10

Number of purple sections = 6

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

a) probability that the spinner will land on purple purple

P(purple) =

$=\dfrac{6}{10} = 0.6$

0.6 is the probability that the spinner will land on purple purple.

b) Interpretation of probability

$0.6\times 100\% = 60\%$

There is a 60% chance that the spinner will land on purple color.
