Talking as if the balls do not get put back into the bag, the first probability is 3/10 for yellow. For red it will be 7/9 because there is one less ball (yellow) in the bag.

Answer:

1.875

Step-by-step explanation:

the average rate of change of g(x) in the closed interval [ a, b ] is

\frac{g(b)-g(a)}{b-a}

here [a, b ] = [- 1, 3 ] , then

g(b) = g(3) = 2³ + 1 = 8 + 1 = 9

g(a) = g(- 1) = 2^{-1} + 1 = \frac{1}{2} + 1 = 1.5

then

average rate of change = \frac{9-1.5}{3-(-1)} = \frac{7.5}{4} = 1.875

A one dollar coin, a two dollar coin and a six sided dice are tossed. how many results are possible?
bonufazy [111]
<span>24. The number of results is simply the product of the number of possibilities for each object tossed. Each coin may lands heads up, or tails up, for 2 possibilities each. And the die may land with 6 possible faces up. So the number of possibilities is 2 * 2 * 6 = 24. So the total number of possible results is 24.</span>

A central angle θ in a circle of radius 4 m is subtended by an arc of length 5 m. find the measure of θ in degrees. (round your
koban [17]

Answer:

\theta=71.6\°

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

C=2\pi r

we have

r=4\ m

substitute the values

C=2\pi (4)=8 \pi\ m

step 2

Remember that

360 degrees subtends the arc of length  8 \pi\ m (circumference)

so

by proportion

Find the measure of θ by an arc of length 5 m

assume \pi=3.1416

\frac{360}{8\pi}=\frac{\theta}{5}\\ \\ \theta=360*5/8\pi \\ \\ \theta=71.6\°
