In a concert band, a the probability that a member is in the brass section is
0.50. The probability that a member plays trombone, given that he or she is in
the brass section, is 0.24.
What is the probability that a randomly selected band member is in the brass
section and plays trombone?
O A. 0.74
• B. 0.48
• C. 0.26
• D. 0.12
Using conditional probability, the probability that a randomly selected band member is in the brass section and plays trombone is:
D. 0.12
What is Conditional Probability?Conditional probability is the probability of one event happening, considering a previous event. The formula is:
\(P(B|A) = \frac{P(A \cap B)}{P(A)}\)
In which:
P(B|A) is the probability of event B happening, given that A happened.\(P(A \cap B)\) is the probability of both A and B happening.P(A) is the probability of A happening.For this problem, the events are:
Event A: Student in the brass section.Event B: Student plays trombone.Hence the parameters are:
P(A) = 0.5, P(B|A) = 0.24.
The probability of both events is found as follows:
\(P(B|A) = \frac{P(A \cap B)}{P(A)}\)
\(P(A \cap B) = P(B|A)P(A) = 0.24 \times 0.5 = 0.12\)
Hence option D is correct.

Use the geometric sequence to help write a recursive rule and an explicit rule for any geometric sequence. for general rules, the values are of n and consecutive integers starting with 1.
Question: Use the geometric sequence to help write a recursive rule and an explicit rule for any geometric sequence:
Solution:
A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant. Remember that the constant factor (ratio) between consecutive terms of a geometric sequence is called the common ratio. Now, given a geometric sequence with the first term a1 and the common ratio r, the nth (or general) term is given by:
\(a_n\text{ = }a_1r^{n-1}\)Thus, in this case, the common ratio r is:
\(r\text{ = }\frac{10}{5}\text{ = 2}\)On the other hand, the first term of the sequence is a1 = 5. Then, we can conclude that the explicit rule for the given sequence is:
\(a_{n\text{ }}=5(2)^{n-1}\)this is equivalent to:
\(a_{n\text{ }}=5.2^n.2^{-1}\)this is equivalent to:
\(a_{n\text{ }}=\frac{5}{2}.2^n\)Then, the correct answer is:
The general rule:
\(a_{n\text{ }}=\frac{5}{2}.2^n\)the recursive rule:
\(a_1=\text{ 5}\)\(a_{n\text{ }}=\frac{5}{2}.2^n\)A recipe calls for 2 cup of brown sugar for every 6 cups of white sugar. How many cups of brown sugar are required for every 12 cups of white sugar?
(PLEASE HELP!!)
There are 4 cups of brown sugar are required for every 12 cups of white sugar.
A recipe calls for 2 cups of brown sugar for every 6 cups of white sugar. We can set up a proportion to find the relationship between the two quantities:
2 cups brown sugar / 6 cups white sugar = x cups brown sugar / 12 cups white sugar
To find the number of cups of brown sugar required for 12 cups of white sugar, we can cross-multiply and then solve for x:
2 cups brown sugar × 12 cups white sugar = 6 cups white sugar × x cups brown sugar
24 cups brown sugar = 6x cups brown sugar
x = 24/6
x = 4
So, 4 cups of brown sugar are required for every 12 cups of white sugar.

The number of gallons of milk in a tanker truck at time t, in minutes, is modeled by m(t). Interpret the
meaning of the following values in the context of the problem. m' (12) = -15
we can interpret the value of \(m'(12) = -15\) as the instantaneous rate of change of the amount of milk in the tanker truck, which is decreasing by 15 gallons per minute at time \(t = 12\) minutes.
What is the derivative of the function?The expression "m'(12)" represents the derivative of the function m(t) with respect to time t, evaluated at t=12. Geometrically, the derivative represents the instantaneous rate of change of the function at the point t=12.
In this case, m'(12) = -15 means that at the time t=12 minutes, the rate of change of the number of gallons of milk in the tanker truck is -15 gallons per minute. This indicates that the amount of milk in the truck is decreasing at a rate of 15 gallons per minute at time t=12.
To calculate m'(12), you need to take the derivative of the function m(t) with respect to t and then evaluate the result at t=12. Assuming you have the expression for m(t), the steps are as follows:
Differentiate m(t) with respect to t:
\(m'(t) = d/dt [m(t)]\)
Evaluate \(m'(t) at t=12:\)
\(m'(12) = m'(t=12)\)
Therefore, we can interpret the value of \(m'(12) = -15\) as the instantaneous rate of change of the amount of milk in the tanker truck, which is decreasing by \(15\) gallons per minute at time t = 12 minutes.

Solve 3x - 6=9 what is the answer?
Answer:
x = 5
Step-by-step explanation:
Step 1: Add both sides by 6:
(3x - 6 = 9) + 6
3x = 15
Step 2: Divide both sides by 3 to isolate and solve for x:
(3x = 15) / 3
x = 5
Optional Step 3: We can check that we've found the correct answer by plugging in 5 for x and checking that we get 9:
3(5) - 6 = 9
15 - 6 = 9
9 = 9

Step-by-step explanation:

The cost of one teaspoon of basil is $0.23. Therefore, option D is the correct answer.
We need to find the cost of basil per teaspoon.
How to interpret the data table?Interpretation of the data table is as follows:
Identify the subject under study.Identify the variable(s) presented in the table.Identify the measuring unit used (frequencies, percentages, rates, etc.)Read the information presented in table cells.Let the cost of one teaspoon of basil be $x, oregano be $y and parsley be $z.
Now, x+2y+3z=1.06-----(1), x+y+2z=0.72-----(2) and 2x+2y+z=0.99-----(3)
Equation (1)-(2), we get
x+2y+3z-(x+y+2z)=1.06-0.72
⇒y+z=0.34-----(4)
⇒z=0.34-y
Substitute z=0.34-y in equation (3).
That is, 2x+2y+0.34-y=0.99
⇒2x+y+0.34=0.99
⇒2x+y=0.65---(5)
Substitute z=0.34-y in equation (2)
Equation (5)-(4), we get
x+y+2(0.34-y)=0.72
⇒x+y+0.68-2y=0.72
⇒x-y=0.04-----(6)
Add equations (5) and (6), and we get
2x+y+x-y=0.65+0.04
⇒3x=0.69
⇒x=0.23
Therefore, the cost of basil per teaspoon is $0.23.

Mrs. Taylor’s science class counted the number of each bird in the schoolyard.
The table shows the results. Mrs. Taylor made a bar graph. Each grid line represents 2 birds.
The bar for Cardinal is 2 grid lines higher than the bar for Carolina wren. How many cardinals did the class see?
Type of Bird Number of Birds
Carolina Wren 6
Eastern Towhee 14
European Starling 9
Cardinal ___?
Answer:
Step-by-step explanation:
If each grid line on the bar graph represents 2 birds, then the difference of 2 grid lines between the bar for Cardinal and Carolina Wren represents:
2 grid lines x 2 birds/grid line = 4 birds
Therefore, the number of cardinals the class saw is:
Carolina Wren + 4 birds = 6 birds + 4 birds = 10 birds
So the class saw 10 Cardinals.
T/F. victor found 5 cars online that he will go to see. the prices of the cars are: $5,000; $4,500; $5,500; $3,999; and $4,999. the median car price is $4,799.60.
False
The median car price is the one right in the middle of the price list. To find the median, we first need to rank the prices from lowest to highest.
The ordered price list looks like this:
$3,999; $4,500; $4,999; $5,000; The median price is $4,999, which is the median price. The average price is not $4,799.60.
Median is a measure of the central tendency of a dataset. The value that separates the top and bottom halves of the record. To find the median, we need to enter the values in the dataset in order from lowest to highest. If the dataset has an odd number of values, the median is the mean.
For example, given the following five values: For 3, 5, 7, 9, 11, the median is the median, so the median is 7. If the dataset has an even number of values, the median is the average of the two middle values. For example, given the following 6 values:
For 3, 5, 7, 9, 11, 13, the median is (7 + 9)/2 = 8. In this case, there are 5 values, which are odd, so the median is the median. , which is $4,999.
