Answer:

The probability is \frac{1}{2}

Step-by-step explanation:

Given,

The portion of the green in the spinner = \frac{3}{10}

So, the probability of green = \frac{3}{10},

While, portion of the blue in the spinner = \frac{1}{5}

So, the probability of blue = \frac{1}{5}

Thus, the probability of getting either blue or green on the spinner = probability of green + probability of blue

=\frac{3}{10}+\frac{1}{5}

=\frac{3+2}{10}

=\frac{5}{10}

=\frac{1}{2}

Measure of E is congruent to K, so E is 50 degrees.

Measure of G is congruent to L, so G is 105 degrees.

Measure of F is congruent to J, J is 180 deg - 50 deg - 105 deg = 25 degrees, so F is 25 degrees.

Drupady [299]

Twelve people join hands for a circle dance.In how many ways can they do this? Suppose six of these people are men, and the other six are women. In how many ways can they join hands for a circle dance, assuming they alternate in gender around the circle

Answer:

86400 ways

Step-by-step explanation:

Since the circle can be rotated, the number of ways to arrange a distinct number of n objects in a circle will be (n−1)!.

Now, if we rotate the circle with the six women, we will see that there are 5! ways with which they can be placed in the circle.

After picking the places for the women, we will now fill each gap between two women with a man.

We have 6 men. Thus, number of ways to arrange the men is 6!

Thus,number of ways they can join hands for a circle dance, assuming they alternate in gender around the circle = 5! × 6! = 86400 ways

The table below represents the distance of a car from its destination as a function of time.
KIM [24]
We are given the table that projects the distance of the car per hour. x is associated to time while y is associated to distance. The equation of the line after plotting in MS Excel is y = 900 - 50x. Hence the y-intercept is equal to 900 while the slope is equal to -50. The domain of the function that is x is all positive numbers.
