36. Two marbles are drawn without replacement from a box with 4 white, 6 green, 3 red and 2 blue marbles. Find the probability both marbles are red.
The probability of drawing both marbles as red is 1/35.
To obtain the probability of drawing two red marbles without replacement, we need to calculate the probability of drawing one red marble on the first draw, and then the probability of drawing a second red marble given that the first marble was red.
The probability of drawing a red marble on the first draw is given by:
P(Red on 1st draw) = (number of red marbles) / (total number of marbles)
= 3 / (4 + 6 + 3 + 2)
= 3 / 15
= 1/5
After the first red marble is drawn, there are now 2 red marbles remaining out of a total of 14 marbles.
The probability of drawing a second red marble given that the first marble was red is:
P(Red on 2nd draw | Red on 1st draw) = (number of red marbles remaining) / (total number of marbles remaining)
= 2 / 14
= 1/7
To find the probability of both marbles being red, we multiply the probabilities of each event:
P(Both marbles are red) = P(Red on 1st draw) * P(Red on 2nd draw | Red on 1st draw)
= (1/5) * (1/7)
= 1/35

Your crazy banker presents another investment opportunity for 2023, where you are told that for the first six months of the year you will have an APR of r_1 compounded monthly, and for the second half of the year the APR will be r_2 compounded daily. Assume that monthly interest compounds on the 28th day of each month, and daily interest compounds at 11:59PM.
1. The banker tells you that for the first six months of the year the effective continuous rate is a_1 = 6%, but they refuse to divulge the value of r_1 directly. You choose to invest $1000 on January 1, 2023, and decide to withdraw all funds from the account on June 30, 2023. What was the value of your account upon withdrawal?
2. The banker then informs you that for the last six months of the year the effective annual rate is c_2 = 10%. You decide that it would be nice to have exactly $4000 in this account at 5PM on December 15, 2023. What amount of money do you need to invest in this account on July 1, 2023, in order to accomplish this goal?
1. The value of your account upon withdrawal on June 30, 2023, was $1,031.49.
To calculate the value of the account upon withdrawal, we need to use the formula for compound interest. The future value (FV) of the account is given by:
FV = P * (1 + r_1/n)^(n*t)
Where P is the principal amount ($1000), r_1 is the monthly interest rate, n is the number of compounding periods per year (12 for monthly), and t is the time in years (6 months = 0.5 years).
Since the effective continuous rate a_1 is given as 6%, we can determine r_1 using the formula r_1 = ln(1 + a_1). Substituting the value of a_1 = 6% into the equation, we find r_1 = ln(1 + 0.06).
Now we can substitute the values of P, r_1, n, and t into the formula to calculate the future value FV. Plugging in these values, we find that the value of the account upon withdrawal is approximately $1,031.49.
2. To have exactly $4000 in the account on December 15, 2023, you need to invest approximately $3,857.02 on July 1, 2023.
We need to calculate the present value (PV) of the desired future value ($4000) to determine the amount of money to invest. The present value formula is:
PV = FV / (1 + r_2)^n
Where FV is the desired future value, r_2 is the daily interest rate, and n is the number of compounding periods.
Since the effective annual rate c_2 is given as 10%, we can determine r_2 using the formula r_2 = (1 + c_2)^(1/365) - 1. Substituting the value of c_2 = 10% into the equation, we find r_2 = (1 + 0.1)^(1/365) - 1.
Now we can substitute the values of FV, r_2, and n into the present value formula to calculate the required investment. Plugging in these values, we find that you need to invest approximately $3,857.02 on July 1, 2023.

The mean number of words per minute (WPM) typed by a speed typist is 119 with a standard deviation of 15 WPM. What is the probability that the sample mean would differ from the population mean by greater than 4.1 WPM if 33 speed typists are randomly selected? Round your answer to four decimal places.
Answer:
the probability that the sample mean would differ is 0.1164
Step-by-step explanation:
The computation of the probability is shown below
= 1 - P(Within 4.1 WPM)
= 1 - P( -4.1 ÷ 15÷ √3 <z < 4.1 ÷ 15÷ √3)
= 1 - P(-1.57 < z < 1.57)
= 1 - 0.8836
= 0.1164
Hence, the probability that the sample mean would differ is 0.1164
Therefore the same would be applied and relevant

An airplane is at 32000 feet above sea level and the seeds at an average rate of 1000 feet per minute how many minutes will it take for the airplane to land at an airport 3000 feet above sea level
Answer:
29 minutes
Step-by-step explanation:
Let
x = number of minutes
y = the height of the airplane above sea level in feet
y = 32,000 - 1000x
y = 3,000
Therefore,
y = 32,000 - 1000x
3,000 = 32,000 - 1000x
3,000 - 32,000 = -1000x
-29,000 = -1,000x
x = -29,000 / -1,000
x = 29 minutes
it will take 29 minutes for the airplane to land at an airport 3000 feet above sea level
Rx: Heparin 40 000 units in D5W 1000 mL Drug available: Heparin 10 000 units/mL 2 mL single-dose vial How much heparin solution would be injected into the D5W 1000-mL bag?
A. 1 ml
B. 2 mL
C. 4 mL
D. 8 mL
6. With reference to question 5, how many heparin vials would be pulled from inventory to prepare the heparin infusion?
A. 1
B. 2
C. 3
D. 4
To prepare the heparin infusion with a concentration of 40,000 units in 1,000 mL, 4 mL of the heparin solution should be injected into the D5W 1,000 mL bag, i.e., Option C and B are the correct answers.
Since the available heparin solution has a concentration of 10,000 units/mL and the desired concentration is 40,000 units in 1,000 mL, we need to determine the volume of the 10,000 units/mL solution to achieve this concentration.
By setting up a proportion, we can calculate the volume of the heparin solution needed:
10,000 units / 1 mL = 40,000 units / x mL
Cross-multiplying gives us:
10,000x = 40,000
Solving for x:
x = 40,000 / 10,000
x = 4 mL
Therefore, 4 mL of the heparin solution would be injected into the D5W 1,000 mL bag to prepare the heparin infusion.
For the second question, since each vial contains 2 mL and we need 4 mL, we would need to pull 2 vials from inventory to prepare the heparin infusion.
In conclusion, the answer to question 5 is A. 4 mL, and the answer to question 6 is B. 2.

Suppose set A has 8 distinct elements. Explain the counting method, don't just write down a formula. If you use a formula, explain why it works. (a) How many relations are there on set A?
"
There are 28 relations on set A.
To determine the number of relations on set A, we need to understand the concept of a relation. A relation between two sets A and B is a set of ordered pairs (a, b) where a is from set A and b is from set B. In this case, both sets A and B are the same, so we are looking for relations within set A.
In a relation on set A, each element of A can be related to any other element of A, including itself. This means that for each pair of elements in set A, we have two possibilities: either they are related or they are not.
Since there are 8 distinct elements in set A, for each pair, we have two choices: either they are related or not related. Therefore, for each pair of elements, we have 2 possibilities.
Now, the total number of relations on set A can be calculated by multiplying the number of possibilities for each pair of elements. Since there are 8 distinct elements in set A, there are (8 choose 2) pairs of elements in total.
Using the binomial coefficient formula, (n choose k) = n! / (k!(n-k)!), we can calculate (8 choose 2):
(8 choose 2) = 8! / (2!(8-2)!)
= (8 * 7) / (2 * 1)
= 28
Therefore, there are 28 different relations on set A.

On a six-day vacation, the forecast is a 60% chance of rain every day. What's the probability that it rains every day? Enter a fraction or round your answer to 4 decimal places, if necessary, Out of 419 applicants for a job, 152 have over 10 years of experience and 63 have over 10 years of experience and have a graduate degree. Step 1 of 2: What is the probability that a randomly chosen applicant has a graduate degree, given that they have over 10 years of experience?
The probability that it rains every day on a six-day vacation, given a 60% chance of rain each day, can be calculated by multiplying the individual probabilities. The probability of rain on any given day is 0.6, so the probability of rain every day is (0.6)^6 = 0.046656, rounded to 4 decimal places. Therefore, the probability of rain every day during the vacation is approximately 0.0467.
In the case of the job applicants, we are given that out of 419 applicants, 152 have over 10 years of experience and 63 have both over 10 years of experience and a graduate degree. To find the probability that a randomly chosen applicant has a graduate degree, given that they have over 10 years of experience, we need to calculate the conditional probability.
The conditional probability is determined by dividing the number of applicants with both over 10 years of experience and a graduate degree (63) by the total number of applicants with over 10 years of experience (152). Therefore, the probability is 63/152, which is approximately 0.4145, rounded to 4 decimal places. Thus, the probability that a randomly chosen applicant has a graduate degree, given that they have over 10 years of experience, is approximately 0.4145.

b. The null and alternative hypotheses would be: ___________
a. For this study, we should use the z-test.
b. The null and alternative hypotheses would be: Null hypothesis: H0: p = 0.55
Alternative hypothesis: H1: p ≠ 0.55
Explanation:
We use the z-test when we are testing the difference between the sample mean and the population mean. Here we are testing the difference between the sample proportion (p) and the population proportion (P).
We should use the z-test for this study to check whether the proportion of voters who prefer the Democratic candidate is significantly different from 55% at a level of significance of a = 0.05. This is because we are testing the proportion of people who prefer a Democratic candidate from a population. Here, we will use the sample size, sample proportion, and level of significance to calculate the test statistic (z) value.
The null hypothesis is H0: p = 0.55, which states that there is no difference between the proportion of voters who prefer the Democratic candidate and the population proportion.
While the alternative hypothesis is H1: p ≠ 0.55, which states that there is a significant difference between the proportion of voters who prefer the Democratic candidate and the population proportion.

Answer:
By substituting the values of A, C, and D the equation modelling the function is;
g(x) = 3·sin(x - π/2) - 4
Step-by-step explanation:
From the given information, we have;
The vertical stretch of the sine function = 3 × The parent function
∴ A = 3
Given that the horizontal shift left = π/2 units, (from an online source with similar question)
The vertical shift down = 4 units
The given function, g is g(x) = A·sin(x + C) + D
Where;
A = The amplitude = The maximum displacement from the rest or equilibrium position = 3
C = The horizontal shift = -π/2 (The negative sign is for the shifting to the left)
D = The vertical shift = -4 (The negative sign is for a shift in the downward direction)
