It’s C)21/20 because for tan you do the opposite side over the adjacent. SOHCAHTOA (sin: opposite/hypotenuse cos: adjacent/hypotenuse tan: opposite/adjacent)

Juanita has a bag of marbles. Without looking, she removes one marble, notes the color and replaces it. She repeats this process
Svetllana [295]

Given table:

color ----- Frequency

Red ------ 14

Green ----- 19

Blue -------- 21

Yellow ----- 16

Number of process repeated (trials) = 70 times

Probability (event) = number of times the event occurs / total number of trials

From the table we can see that the number of times she pick the blue marble is 21

Probability of picking a blue marble on next try = \frac{21}{70} = \frac{3}{10}

Three workers at a fast food restaurant pack the take-out chicken dinners. john packs 45% of the dinners, mary packs 25% of the
lyudmila [28]
To calculate this probability is often easier to calculate the complement
the prob that we are looking for is 1-P(No salt packed in dinner)
Note: No salt packed with dinner is the complement event of having salt packed within
so let's find this probability
He is what we know
if John packs 4/45 chance no salt included
if Sue packs 3/70 chance no salt
if Marry packs 2/25 No salt
We are looking into probability is the sum (note these events are disjoint)
final result should be 1- that sum

Help me i don’t know how to do this

Hi!

y = 16

x = 32

<h3 /><h3>In 30-60-90 triangles, the hypotenuse is double the length of the shortest leg, and the longer leg is \sqrt{3} times the shorter leg.</h3>

We are given the longest leg. To find the shortest leg, we must divide the longest leg value by \sqrt{3}

\cfrac{16\sqrt{3} }{\sqrt{3} }

The radicals cancel out and we are left with 16.

The length of y (the shortest leg) is 16.

Now, we also know that the hypotenuse is double the shortest leg. The shortest leg is 16, so if we double that, it's 32.
