Solve the given equation. (Enter your answers as a comma-separated list. Let k be any integer. Round terms to two decimal places

sashaice [31]

Answer:

θ = 60° or θ = 120°, which in radians is equivalent to θ = π/3 rad or θ = 2π/3 rad.

Explanation:

The given equation is sin θ = (√3)/2

Solving that equation is finding the value of the angle, θ, whose sine is (√3)/2.

The function that returns the value of the angle whose sine is (√3)/2 is the inverse function of the sine and it has a special name: arc sine or arcsin.

Hence, θ = arcsin (√3)/2.

You can use your knowledge of the notable angles to solve for that equation.

1) The function sine is positive in first and second quadrants.

2) The angles in the first quadrant go from 0° to 90°.

3) The sine of 60° (√3)/2, Hence the first value of θ is 60°

4) The angles in the second quatrant go from 90° to 120°. 60° is the reference angle in the second quadrant, and the angle searched is

180° - reference angle = 180° - 60° = 120°. So, 120° is the other solution of the equation.

5) You can convert both angles to radians using the equivalence

π radians = 180° ⇒ 1 = π rad / 180°

60° = 60° × π rad / 180° = π/ 3 rad

120° = 120° × π rad / 180° = 2π/3 rad

6) You can verify that sin 60° = (√3)/2 = sin 120° .

A movie theater sold 500 tickets on

Natasha2012 [34]

Answer:

45%

Step-by-step explanation:

225 of 500 can be written as:

225/500

To find percentage, we need to find an equivalent number with denominator 100. Multiply both numerator & denominator by 100

225/500 × 100/100

= (225 × 100/500) ×

1/100

45/100

Therefore, the answer is 45%

Hope this helps :)

After seeing countless commercials claiming one can get cheaper car insurance from an online company, a local insurance agent wa

kifflom [539]

Answer:

Null Hypothesis, $H_0$ : $\mu_d$ = 0

Alternate Hypothesis, $\mu_d\neq$ 0

Step-by-step explanation:

We are given that a local insurance agent randomly selected profiles for 10 of his clients and checked online price quotes for their policies.

Then, based on paired data on the 10 clients (the price he offered them and the corresponding online quote), he obtained t-statistic = 0.709 p-value = 0.248.

Here , we will use the concept of Paired data test statistics because the prices that the local insurance agent offered and the corresponding online quotes are from the same single data. These information has not been taken from the two independent samples.

So, <u>Null Hypothesis</u>, $H_0$ : $\mu_d$ = 0

<u>Alternate Hypothesis</u>, $\mu_d\neq$ 0

Here, null hypothesis states that there is no difference between the price he offered them and the corresponding online quote.

On the other hand, alternate hypothesis states that there is difference between the price he offered them and the corresponding online quote.

Hence, this would be the correct null and alternative hypothesis.

Betsy participates in a scavenger hunt that requires her to retrieve items from 4 locations. The locations are on a map with the

Andreas93 [3]

Answer:

240 yd

Step-by-step explanation:

Let A, B, C, and D represent location 1, location 2, location 3, and location 4 respectively.

Consider the figure in the attached file.

We need to find the total distance traveled by Betsy.

The distance covered by Betsy is

length of segment AB length of segment BC length of segment CD length of segment DA.

To find the distance AB, we need to find the distance from A to B on y-axis.

So, length of segment AB units

To find the distance BC, we need to find the distance from B to C on x-axis.

So, length of segment BC units

To find the distance CD, we need to find the distance from C to D on y-axis.

So, length of segment CD units

To find the distance DA, we need to find the distance from D to A on x-axis.

So, length of segment DA units

Hence, the total distance covered is units

It is given that 1 unit equals 10 yd, so distance traveled by Besty is yd
