Two ropes are attached to a large ballon in a parade. The people holding the ropes are 40 feet apart,and the angle between the t

qaws [65]

Ropes are 9.63 meters ans 8.178 meters.

<u>Step-by-step explanation:</u>

Step 1 :

List all the given things

Distance between people holding ropes = 40 =(40*0.3048) meters = 12.192 meters

Angle between two ropes = 86 degrees

Angle of elevation of one rope = 42 degrees

Step 2 :

Two angles of triangle are already given so third angle can be calculated as -

Third angle = 180 - ( 86 + 42 ) = 52 degrees

Step 3 :

As we know all three angles we will apply sine rule now, which is

$\frac{a}{sine A} = \frac{b}{sine B} = \frac{c}{sine C}$

Step 4 :

By putting values, we have

$\frac{a}{sine 52} = \frac{b}{sine 42} = \frac{12.192}{sine 86}$

Step 5 : Calculating a and b

$a = 12.192 * \frac{sine 52}{sine 86}$ , $b = 12.192 * \frac{sine 42}{sine 86}$

Step 6 :

By putting values of all sine and calculating we get,

a = 9.63 meters and b = 8.178 meters

Tamara is a real estate agent and makes 5% commission on her total sales. She sells a home that worth $350,000. What is her comm

4vir4ik [10]

Since Tamara makes 5% commission on her sales, this in decimal form is presented as .05. So we can find 5% of her $350,000 sale by multiplying her commission rate by her total sale. Her commission rate is .05 and her sale is 350,000, when we multiply that number we get 17,500.
Tamara's commission on this house is $17,500.

Your neighborhood gym tracked how many days

Morgarella [4.7K]

The correct interpretation of the standard deviation of the given discrete distribution is:

The mean number of days a member worked out would typically be about 1.6764 from the expected number of days.

<h3>What are the mean and the standard deviation of a discrete distribution?</h3>

The mean of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.

The standard deviation is the square root of the sum of the difference squared between each outcome and the mean, multiplied by it's respective probabilities.

Hence:

E(X) = 0.4(0) + 0.12(1) + 0.13(2) + 0.15(3) + 0.06(4) + 0.02(5) + 0.02(6) + 0.01(7) = 1.36

$\sqrt{V(X)} = \sqrt{0.4(0-1.36)^2 + 0.12(1-1.36)^2 + 0.13(2-1.36)^2 + \cdots + 0.01(7-1.36)^2} = 1.674$

Hence the correct option is:

The mean number of days a member worked out would typically be about 1.6764 from the expected number of days.
