Answer:

1/4 or 25%

Step-by-step explanation:

Let's see, we want to know probability of an event in which we roll two even numbers.

"We know that probability is defined as number of desired outcomes divided by all possible outcomes"

e - even number

o - odd number

our desired outcome: (e, e) total of 1

all possible outcomes: (e, e), (e, o), (o, e), (o,o) total of 4

that gives us 1/4

Henry found some pants on sale for 60% off. If the pants were originally $100, how much are they now?
vredina [299]
If something is 60% off, that means it is now going to be 40% of its original price because

100 - 60 = 40

To find final price multiply the percentage as a decimal by the price.

40% is 40/100 which as a decimal is 0.4

0.4 x 100 = $40

The pants will be 40 dollars.

arlik [135]

Answer:a. [tex] $f\propto  L$ [\tex]

b. [tex] f \propto \sqrt{T} [\tex]

c. [tex] f \propto \frac{1}{\sqrt{P}} [\tex]

I. Decrease in length increases leads to increase in pitch.

II. Increase in tension leads to increase in pitch.

III. Increase in linear density reduces the pitch

Step-by-step explanation: I. Since the frequency is inversely proportional to the length increase in length leads to decrease in frequency likewise decrease in length leads to increase in frequency.

II. Since the frequency is directly proportional to the square root of the tension increase in tension leads to increase in frequency likewise decrease in tension leads to decrease in frequency.

III.since the frequency is inversely proportional to the square root of the linear density so increase in linear density leads to decrease in frequency and likewise decrease in linear density leads to increase in frequency.

(SAT Prep) Find the value of x.<br> X<br> 125°<br> 115°
Ymorist [56]
<h3>Answer : 60°</h3>

<h3>Way to do </h3>

#look pic for detailed info

180° - 125° = 55°

180° - 115° = 65°

180° - 55° - 65° = 60°

180° - 60° = 120°

180° - 120° = 60°
