. In the casino game roulette, a wheel with 38 spaces (18 red, 18 black, and 2 green) is spun. In one possible bet, the player bets $1 on a single number. If that number is spun on the wheel, then they receive $36 (their original $1 $35). Otherwise, they lose their $1. On average, how much money should a player expect to win or lose if they play this game repeatedly
Answer:
For each game, the player should be expected to lose $0.0263.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Probability of each outcome:
1/38 probability of winning, that is, 1/38 probability of receiving $36.
37/38 probability of losing, that is, 37/38 probability of losing $1.
On average, how much money should a player expect to win or lose if they play this game repeatedly?
For each game:
[tex]E(X) = \frac{1}{38}*36 - \frac{37}{38}*1 = \frac{36 - 37}{38} = -\frac{1}{38} = -0.0263[/tex]
For each game, the player should be expected to lose $0.0263.

Step-by-step explanation:
A university interested in tracking its honors program believes that the proportion of graduates with a GPA of 3.00 or below is less than 0.16. In a sample of 200 graduates, 24 students have a GPA of 3.00 or below. The value of the test statistic and its associated p-value at the 5% significance level are _________, respectively.
Answer:
The value of the test statistic and its associated p-value at the 5% significance level are -1.54 and 0.9382, respectively.
Step-by-step explanation:
A university interested in tracking its honors program believes that the proportion of graduates with a GPA of 3.00 or below is less than 0.16.
This means that the null hypothesis is:
[tex]H_{0}: p \geq 0.16[/tex]
Testing this hypothesis, means that the alternate hypothesis is:
[tex]H_{a}: p > 0.16[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
0.16 is tested at the null hypothesis:
This means that [tex]\mu = 0.16, \sigma = \sqrt{0.16*0.84}[/tex]
In a sample of 200 graduates, 24 students have a GPA of 3.00 or below.
This means that [tex]n = 200, X = \frac{24}{200} = 0.12[/tex]
Value of the test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.12 - 0.16}{\frac{\sqrt{0.16*0.84}}{\sqrt{200}}}[/tex]
[tex]z = -1.54[/tex]
Pvalue:
The pvalue is the probability of finding a sample mean above 0.12, which is 1 subtracted by the pvalue of z = -1.54.
Looking at the z-table, z = -1.54 has a pvalue of 0.0618
1 - 0.0618 = 0.9382
The value of the test statistic and its associated p-value at the 5% significance level are -1.54 and 0.9382, respectively.

Ms. Wall will roll two number cubes. What is
the probability that she will roll a sum of 9 ?
Express your answer as a fraction.
(I'll give brainlist if u get it right)
Answer: 9/1
Step-by-step explanation: Apologies for the mistake. Let's calculate the probability again.
To find the probability of rolling a sum of 9 on two number cubes, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.
For a sum of 9, the following combinations are favorable:
(3, 6), (4, 5), (5, 4), (6, 3)
So, there are 4 favorable outcomes.
The total number of possible outcomes is still 6 × 6 = 36.
The probability of rolling a sum of 9 is:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 4 / 36
Simplifying the fraction, we get:
Probability = 1 / 9
Therefore, the probability of rolling a sum of 9 is 1/9, not 11/18 as previously stated.
What is the circumference of the circle?
Answer:
The circumference of a circle is the distance around the outside of the circle
Hope It Helps :)
Step-by-step explanation:
Answer:
Circumference of the circle or perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of circle defines the region occupied by it. If we open a circle and make a straight line out of it, then its length is the circumference. It is usually measured in units, such as cm or unit m.
When we use the formula to calculate the circumference of the circle, then the radius of the circle is taken into account. Hence, we need to know the value of the radius or the diameter to evaluate the perimeter of the circle.
Circumference of a Circle Formula
The Circumference (or) perimeter of a circle = 2πR
where,
R is the radius of the circle
π is the mathematical constant with an approximate (up to two decimal points) value of 3.14
Again,
Pi (π) is a special mathematical constant; it is the ratio of circumference to diameter of any circle.
where C = π D
C is the circumference of the circle
D is the diameter of the circle
For example: If the radius of the circle is 4cm then find its circumference.
Given: Radius = 4cm
Circumference = 2πr
= 2 x 3.14 x 4
= 25.12 cm
What is the explicit formula for the arithmetic sequence 4/5, 29/30, 17/15, 13/10?
Answer:
The answer is D,
a(n) = 4/5 + 1/6(n- 1)
just took the test :)
Step-by-step explanation:
The explicit formula for the arithmetic sequence is D, a(n) = 4/5 + 1/6(n- 1)
What is arithmetic sequence?An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.
The explicit formula is given by:
[tex]T_n = a + (n-1)d[/tex]
Where a is the first term (4/5) and d is the common difference (the difference is any 2 terms).
Therefore, to find d:
29/30 - 4/5
29/30 - 24/30
d = 5/30
d = 1/6
Now putting them into the formula:
a(n) = 4/5 + 1/6(n- 1)
The last answer choice is right.

Answer:

Step-by-step explanation:
Big rectangle Area = LxW = 18 x9= 162
White triangle Area A = (ab)/2 legs 5 and 8 ( 18-10= 8 )
= (5x8)/ 2 = 20
Subtract white triangle from green rectangle
162-20 = 142
OR
area left rectangle LxW 10x9 = 90
area right rectangle LxW 4x8 =32
area green triangle ( sides 5 an8 ) (ab)/2 = 20
