a spinner is divided into five equal sections labeled 1 to 5. What is the probability that the spinner will land on 3?

Answers

Answer 1
Answer:

Answer: (1)/(5)

Step-by-step explanation:

Given : A spinner is divided into five equal sections labeled 1 to 5.

Thus , the total number of sections on the spinner =5

Number of favorable outcomes =1

Then , the probability that the spinner will land on 3 is given by :-

\frac{\text{Favorable outcome}}{\text{Total outcomes}}\n\n=(1)/(5)

Hence, the probability that the spinner will land on 3 is (1)/(5)
Answer 2
Answer: Since there are 5 options, that's gonna be the denominator. And since there is only one number 3, 1 is our numerator. So the finish fraction is 1/5.

There is 1/5 probability that the spinner will land on 3.

Please answer me x and y ​

Answers

Answer: x=5√3(you've got it correct!)

y=15

In∆ADC,

Cos 60°=DC/10

DC=5

y=20-5

y=15

Answer:

x = 5√3

y = 15

Step-by-step explanation:

Look at the picture.

ΔABC, ΔDBA and ΔDAC are the triangles 30° - 60° - 90°. The sides are in ratio 1 : √3 : 2.

Therefore

in ΔDAC:

DC : AD : AC = 1 : √3 : 2

If AC = 10, then DC = 10 : 2 = 5 and AD = x = 5√3

in ΔDBA:

AD : BD : AB =  1 : √3 : 2

If AD = 5√3, then AB = 2 · 5√3 = 10√3 and BD = y = 5√3 · √3 = 5 · 3 = 15

What is the rectangular form of the polar equation?


θ=−7π/6

Answers

The rectangular form of the polar equation   \theta=(-7\pi )/(6) is:

x = r * (\sqrt3)/(2)\ny = r * (-1)/(2)

Mathematical formulations known as polar equations show the connections between locations in a polar coordinate system. In a polar coordinate system, a point's distance from the origin serves as its definition.

To convert a polar equation into a rectangular form, we can use the following formulas:

x = r * cos(\theta)\ny = r * sin(\theta)

In this case, the polar equation is  \theta=(-7\pi )/(6).

Using the conversion formulas, we can substitute the value of θ into these equations:

x = r * cos\left((-7\pi)/(6)\right)\ny = r * sin\left((-7\pi)/(6)\right)

Evaluate the trigonometric functions cos\left((-7\pi)/(6)\right)\n and sin\left((-7\pi)/(6)\right).

cos\left((-7\pi)/(6)\right) = cos\left(\frac {\pi}{6}\right) = (\sqrt3)/(2)

sin\left((-7\pi)/(6)\right) = -sin\left( (\pi)/(6)\right)\n=( -1)/(2)

Substituting these values back into the equations:

x = r * (\sqrt3)/(2)\ny = r * (-1)/(2)

The measure of an angle is 3/4 of 60 degrees. What is the measure of the complementary angle?

Answers

First we can convert the fraction into a decimal which would be 0.75. Then we continue to multiply  0.75 by 60 which would then give us the answer. 0.75*60=45 degrees We can prove this by dividing 90/2 which equals 45 because 2 complementary angles add up to 90 degrees. 45 degrees is the final answer. Hope this helps!

3/4 x 60/1 = 40 I don't know I'm sorry.
