B. M= S - C
C. M= SC
D. M= s/c
To solve for M in the formula S = C + M, subtract C from both sides of the equation.
To solve for M in the formula S = C + M, we need to isolate the variable M on one side of the equation. To do this, we can subtract C from both sides of the equation:
S - C = C + M - C
S - C = M
Therefore, the correct answer is B. M = S - C.

Step-by-step explanation:
Answer:
The probability is
Step-by-step explanation:
From the question we are told that
Th The population mean
The standard deviation is
The values considered is
Given that the distribution of the amounts spent follows the normal distribution then the percent of the adults spend more than $2,550 per year on reading and entertainment is mathematically represented as
Generally
So
substituting values
From the normal distribution table the value of is
Thus
We calculate the z-score for the amount $2,550 using the given mean and standard deviation. The z-table gives us the percentage of people who spend less than this, which we subtract from 1 to find the percentage who spend more. Approximately 16.85% of adults in the 25- to 34-year age group spend more than $2,550 on reading and entertainment each year.
To compute the percentage of adults spending more than $2,550 per year, we must first find the z-score associated with this value. The z-score is a measurement of how many standard deviations a particular data point is from the mean.
The formula for calculating the z-score is: Z = (X - μ) / σ.
Where:
- X is the value we are interested in.
- μ is the mean.
- σ is the standard deviation.
Using this formula, the z-score for $2,550 is:
Z = ($2,550 - $1,999) / $574 = 0.96.
Next, we need to use a z-table or a standard normal distribution table to find out the probability that lies below the calculated z-score. Looking this up on a z-table, we get a value of 0.8315, meaning that 83.15% of the population will spend $2,550 or less per year on reading and entertainment. Since we want to know the percentage spending more than $2,550, we subtract this value from 1: 1 - 0.8315 = 0.1685.
Therefore, based on the given mean and standard deviation, about 16.85% of adults in the 25- to 34-year age group spend more than $2,550 on reading and entertainment each year.

Answer:
15595 bacteria will be present after 13 hours.
Step-by-step explanation:
Continuous population growth:
The continuous population growth model, for the population after t hours, is given by:
In which P(0) is the initial population and r is the growth rate.
Started with 5000 bacteria
This means that
So
After three hours it grew 6500 bacteria:
This means that . We use this to find r.
So
How many bacteria will be present after 13 hours?
This is P(13). So
Rounding to the nearest whole number
15595 bacteria will be present after 13 hours.

Answer: The required equation of the ellipse in standard form is
Step-by-step explanation: We are given to find the equation of an ellipse in standard form with the vertical major axis of length 10 units and minor axis of length 8 units.
Since the major axis is vertical, so it will lie on the Y-axis. Let the standard form of the ellipse be given by
where the length of major axis is 2a units and length of minor axis is 2b units.
According to the given information, we have
and
Substituting the values of a and b in equation (i), we get
Thus, the required equation of the ellipse in standard form is
