Jasmine has a bag which contains a nickel, a penny, and a dime. Find the probability of getting a nickel first and then a penny
stepan [7]

Answer:

0.166 = 16%

Step-by-step explanation:

There are three different options to pick in the bag, so the probability of getting a nickel first is 1/3, and then the probability of getting a penny without replacing the nickel is 1/2, as there will be only 2 options remaining after the nickel was picked.

So the final probability is the product of these probabilities:

P = (1/3) * (1/2) = 1/6 = 0.166 = 16%

PLS HELP <br>find the unknown side of the triangle below (round to the nearest tenth) <br>​
Nonamiya [84]
22.9 is the closest but not exact. It was probably rounded off.

I used the formula: leg^2+leg^2=hypotenuse^2

(You can use that formula for any right triangle.)

12x=132
x=11
angle of WIJ is 10x
angle of HIW is 2x+13
to find angle of HIW, you plug in x=11 into 2x+13 and
the answer and angle of HIW is 35 degrees.
