Question:
The probability that a UCR undergraduate majors in Nursing is 0.15. The probability that a UCR undergraduate is a Junior is 0.20. The probability that a UCR undergraduate is a Junior or a Nursing major is 0.085. What is the probability that a UCR undergraduate is a Junior and a Nursing major?
Answer:
[tex]P(J\ and\ N) = 0.265[/tex]
Step-by-step explanation:
Given
Represent Junior with J and Nursing Major with N.
So, we have:
[tex]P(N) = 0.15[/tex]
[tex]P(J) = 0.20[/tex]
[tex]P(J\ or\ N) = 0.085[/tex]
Required
Determine [tex]P(J\ and\ N)[/tex]
In probability, for events A and B
[tex]P(A\ and\ B) = P(A) + P(B) - P(A\ or\ B)[/tex]
In this case:
[tex]P(J\ and\ N) = P(J) + P(N) - P(J\ or\ N)[/tex]
Substitute values for P(J), P(N) and P(J or N)
[tex]P(J\ and\ N) = 0.20 + 0.15 - 0.085[/tex]
[tex]P(J\ and\ N) = 0.265[/tex]
Hence, the probability that an undergraduate is a Junior and major in Nursing is 0.265

A recent survey of people who eat salad suggest that 78% like tomatoes on their salad, 49% like cheese on their salad, and 36% like both tomatoes and cheese on their salad. Suppose a person who eats salad is selected at random, and find they like cheese on their salad. What is the probability that the person also likes tomatoes on their salad?
0.29
0.46
0.49
0.73
Answer:
D) 0.73
Step-by-step explanation:
If we take the number of people liking cheese on their salad and divide it by the people who like both we get our result.
36%/49%
=
.36/.49
=
.73 or D
The conditional probability that the person also likes tomatoes on their salad is of 0.73.
What is Conditional Probability?Conditional probability is the probability of one event happening, considering a previous event. The formula is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which:
P(B|A) is the probability of event B happening, given that A happened.[tex]P(A \cap B)[/tex] is the probability of both A and B happening.P(A) is the probability of A happening.In this problem, the events are given as follows:
Event A: Person likes cheese.Event B: Person likes tomatoes.Hence, the probabilities are given by:
[tex]P(A) = 0.49, P(A \cap B) = 0.36[/tex].
The conditional probability is given by:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.36}{0.49} = 0.73[/tex]

Question: Write a loop that inputs words until the user enters STOP.
Answer:
count = 0
word = input("User Input: ")
while word!="STOP":
count = count+1
print("You entered: "+str(word))
word = input("User Input: ")
print("All done. "+str(count)+" words entered")
Step-by-step explanation:
This line initializes counter variable count to 0
count = 0
This line prompts user for input
word = input("User Input: ")
The following iteration is executed until user enters STOP
while word!="STOP":
This increments counter variable by 1
count = count+1
This prints the word entered by the user
print("You entered: "+str(word))
This line prompts user for another input
word = input("User Input: ")
This prints the number of input by the user
print("All done. "+str(count)+" words entered")
Answer:
c = 0
word = input("Enter a word: ")
while word!="STOP":
c = c+1
print("#" + str(c) + ": You entered "+str(word))
word = input("Please enter the next word: ")
print("All done. "+str(c)+" words entered.")

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of games downloaded = g
Number of songs downloaded = g + 8
Total number of songs and games downloaded = 30
Now,
g + (g + 8) = 30
g + g + 8 = 30
2g + 8 = 30
Subtract 8 on both sides.
2g = 30 - 8
2g = 22
Divide 2 on both sides.
g = 11
The number of games = 11
The number of songs = 11 + 8 = 19
Thus,
The number of games is 11.
The number of songs is 19.

Answer:
a. 6
b. 12
c. [tex] y = 6x + 12 [/tex]
Step-by-step explanation:
a. Using two pairs of values given, (0, 12) and (1, 18)
Rate/slope = [tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{18 - 12}{1 - 0} = \frac{6}{1} = 6 [/tex]
Unit rate/slope (m) = 6
b. The starting value is the y-intercept (b). It is the value of of y when x = 0.
From the table, when x = 0, y = 12.
Therefore the starting value (b) would be 12.
c. The equation can be written in slope-intercept form, [tex] y = mx + b [/tex], where,
m = slope/rate = 6
b = starting value/intercept = 12.
Plug in the values into the equation
The equation would be:
✅[tex] y = 6x + 12 [/tex]

A coffee table is shaped like a square and has an area of 22 square feet. Find the length of the side of the table to the nearest tenth of a foot.
Answer:
4.69 feet
Step-by-step explanation:
If the table is a square, all the sides are equal and the area is the length of one side squared. A=l^2
The length must then be the square root of the area. The square root of 22 square feet is 4.6904 feet. Rounded to the nearest tenth, that is 4.69 feet.

A line intersects the y-axis of the point (a, b) Is a = 0? Is b = 0? Explain.
9514 1404 393
Answer:
a=0
b may be 0 but is not required to be
Step-by-step explanation:
The y-axis corresponds to the line x=0. Any point on the y-axis will have an x-coordinate of 0.
If (a, b) is on the y-axis, then a = 0.
If the intersection point is (0, 0), then b=0. Otherwise, b is not 0.
In a standard Normal distribution, what percentage of observations lie between z = 0.37 and z = 1.65?
Find the z-table here.
30.62%
40.52%
59.48%
69.38%
Answer:
c
Step-by-step explanation:
The solution is, The percent is 4.9471%
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
given that,
Here, we want to find the percentage of observations that lie above
z = 1.65
Firstly we find the probability of x < z = 1.65
Hence P ( x > 1.65)
This is obtainable from the standard normal distribution table
The value of P(x > 1.65) = 0.049471
This represents a percentage of 4.9471%
Hence, The solution is, The percent is 4.9471%
