A sales analyst listed the probabilities of profits and losses in dollars for a certain company. Find the mean for the probabili

kakasveta [241]

Answer: The mean for the probability distribution will be 69.25.

Explanation:

Since we given that

$At\ x_1= -500 ,P(x) = 0.076\\$

$At\ x_2= -250,P(x)= 0.191\\$

$At\ x_3=0, P(x)= 0.265\\$

$At\ x_4=250 , P(x)= 0.316\\$

$At\ x_5=500 , P(x)= 0.152\\$

As we know the formula for expectation of x i.e. known as mean for the probability distribution,

$E(x)=x\sum_{1}^{5} P(x)$

So, we apply this formula in our case,

$-500\times 0.076+(-250)\times 0.191+0\times 0.265+250\times 0.316+500\times 0.512=69.25$

$\mu = 69.25$

Hence, the mean for the probability distribution will be 69.25.

The larger of two numbers is 15 more than three times the smaller number. If the sum of the two numbers is 63, find the numbers

Amanda [17]

Answer:

The smaller number equals 12, the larger number equals 51.

Step-by-step explanation:

x + (3x + 15) = 63

Combine like terms.

4x + 15 = 63

Subtract 15 from both sides.

4x + (15 -15) = (63 - 15)

4x = 48

Divide both sides by 4.

4x/4 = 48/4

x = 12

Check answer.

12 + (3(12) + 15) = 63

12 + 36 + 15 = 63

63 = 63

Find the value of csc theta, if cos =-3/5; 90 degrees < theta < 180 degrees

Sloan [31]

Answer: $\frac{5}{4}$

Step-by-step explanation:

Given

$\cos \theta =\frac{-3}{5}$

and $\theta$ lies between

$90^{\circ}$

and for this $\theta$ , $\sin$ and $\text{cosec}$ is Positive as they lie in 2 nd Quadrant

$\sin ^2\theta +\cos ^2\theta =1$

$\sin ^2\theta =1-(\frac{-3}{5})^2$

$\sin ^2\theta =1-\frac{9}{25}$

$\sin ^2\theta =\frac{16}{25}$

$\sin \theta =\frac{4}{5}$

$\therefore \text{cosec}\ \theta =\frac{5}{4}$

Is the answer number 1? I can't get anymore wrong sorry for lengthy problem thanks!

mezya [45]

The area of the circle shown would not be 5pi. If you look closer, the area is 25pi, therefore the answer is 3. I hope this helps!
