This is a question for a test. I don't want sound mean but, next time please put in the work.
Step-by-step explanation:
Answer:
36
Step-by-step explanation:
I drew a diagram on paper but cant here soooo....
but math checks out i think.
Angles AOD and COB are both 36.
Angles AOC and DOB are both 144.
DOB has to be 4 times angle COB, right? if so, then:
144 = 4*36. That checks out. Now to see if all the angles combined are 360.
36 + 36 + 144 + 144 =360. It works!
This is my first answer ever btw so if the formatting and grammar is bad im sorry.

HINT: Find the equation of the line in the Slope Intercept
form and set x = 7.
1) Find the slope.
2) Use the point slope method to get the equation of the line.
Write the equation in Slope Intercept form.
3) Substitute 7 for x to get the answer.
Answer:
Samantha will earn $1,150 on the 7th day.
Step-by-step explanation:
Linear Modeling
It consists of finding the equation of a line that represents the data provided in a specific situation.
Tina's (or Samantha's) earnings are $550, x, $750,... where x is an unknown amount for the second day of her new restaurant.
The earnings continue to increase at the same rate until the 7th day. We must find the earnings for that last day.
The linear model can be found in several ways. We'll use the slope-point form of the line, finding first the slope and then the y-intercept.
The equation of the line in slope-intercept form is:
y=mx+b
Being m the slope and b the y-intercept.
1) Find the slope
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have the points (1,550) and (3,750), thus:
[tex]\displaystyle m=\frac{750-550}{3-1}=100[/tex]
2) Get the equation of the line
Substituting into the equation of the line, we get:
y=100x+b
Select the point (1,550), substitute into the above equation, and solve for b:
550=100(1)+b
Solving:
b=450
Thus we complete the equation of the linear model:
y=100x+450
3) Substitute 7 for x
y=100(7)+450
y=1,150
Samantha will earn $1,150 on the 7th day.

A fair coin is continually flipped until heads appears for the 10th time. Let X denote the number of tails that occur. Compute the probability mass function and the expected value of X.
Answer:
P (X = i) = (i + 9 _ 9) (1/2)^(i + 10)
Step-by-step explanation:
Range of X = {0, 1, 2, 3......10}
P (X = i) = P (NB (10, ½) i = 10)
P (X = i) = (i + 9 _ 9) (1/2)^10 (1/2)^(1+10-10)
P (X = i) = (i + 9 _ 9) (1/2)^10 (1/2)^1
P (X = i) = (i + 9 _ 9) (1/2)^(i + 10)
literal equation
Solve for W.

A distribution of values is normal with a mean of 114.5 and a standard deviation of 23.
Find P47, which is the score separating the bottom 47% from the top 53%.
P47 =
Enter your answer as a number accurate to 1 decimal place. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.
Answer:
The score separating the bottom 47% from the top 53% is 112.8
Step-by-step explanation:
Let X denote the random variable whose values are normal with a mean of 114.5 and a standard deviation of 23.
Compute the 47th percentile as follows:
[tex]P(X<x)=0.47\\\\P(\frac{X-\mu}{\sigma}<\frac{x-114.5}{23})=0.47\\\\P(Z<z)=0.47[/tex]
The corresponding z-value is,
z = -0.075
*Use the z-table.
Compute the value of x as follows:
[tex]\frac{x-114.5}{23}=-0.075\\\\x=114.5-(0.075\times 23)\\\\x=112.775\\\\x\approx 112.8[/tex]
Thus, the score separating the bottom 47% from the top 53% is 112.8
