Dustin has a spinner that is divided into 5 equal-size sections colored pink, blue, orange, white, and green. What is the probability that Dustin spins pink on the 1st spin and then spins a color other than pink on the 2nd spin?
Answer:
1/6
Step-by-step explanation:
1st spin:
1 out of the 5 sections are pink, so the probability of spinning a pink on the 1st spin is 1/5.
2nd spin:
5 out of the 6 sections are not pink, so the probability of spinning a pink on the 2nd is 5/6.
Multiply the probabilities of the two spins to get the answer.

Answer:
The answer is 8.5
Step-by-step explanation:
Just list all the numbers and cross them out one by one.
Add up all of the numbers and divide by the number of numbers in the data set. The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median.

Answer:
x = -44/13
y = -65/13
Step-by-step explanation:
Using matrix form means using the crammers rule
The matrix form of the expression is written as;
[tex]\left[\begin{array}{ccc}8&5\\-1&1\\\end{array}\right] \left[\begin{array}{ccc}x\\y\\\end{array}\right] = \left[\begin{array}{ccc}9\\7\\\end{array}\right][/tex]
AX = B
taking the determinant of A;
|A| = 8(1) - 5(-1)
|A| = 8 + 5
|A| = 13
After replacing the first row with the column matrix;
[tex]A_x =\left[\begin{array}{ccc}9&5\\7&-1\\\end{array}\right][/tex]
|Ax| = 9(-1)-5(7)
||Ax| = -9 - 35
|Ax| = -44
x = |Ax|/|A|
x = -44/13
similarly for y
[tex]A_x =\left[\begin{array}{ccc}8&9\\-1&7\\\end{array}\right][/tex]
|Ay| = 8(7)+9
|Ay| = 56+9
|Ay| = 65
y = |Ay|/|A|
y = -65/13

A company is testing a new protein shake which they claim works better than their existing brand in improving an athlete's performance. The company selected 60 athletes from a training camp database, and divided them into three groups. The ages for the groups were 16 to 20 years, 21 to 25 years, and 26 to 30 years. In each group, half of the subjects were asked to use the new protein shake for a month, and the other half were asked to use the company's existing brand for a month. The subjects were not informed about which protein shake they would be using. Which statements about this study are true? The study uses blocking to reduce variability from known factors.

You know the total measurement of both angles is 180.
So your formula is (2x+54) + x = 180. Now rearrange to get
180 - (2x+54) = x or 180-2x+54 =x
Simply to -2x+126 = x followed by moving x and moving 126 to get
-3x = -126 , now divide both sides by -3
18)
Your complete circle is 360 and you know one angle is 90.
Set your formula to 360=90+(3x)+(x-20)+(2x-10)
Rewrite to 360 = 90+3x+x-20+2x-10 and combine like terms
360 = 90 - 20 - 10 + 3x + x+2x
360 = 60 + 6x
360 - 60 = 6x
300 = 6x
300/6 = x
50 = x
