The process to subtract the mixed fractions with the whole numbers is explained below.

The Mixed Fractions are defined as type of fraction that consists of a whole number and a proper fraction.

Step(i) : We multiply whole number by denominator of fraction and add numerator.

For example, if mixed fraction 2(1/3), we multiply 2 by 3 and add 1 to get 7. So, 2(1/3) is equivalent to improper fraction 7/3.

Step(ii) : Find a common denominator for fractions. We find least common multiple (LCM) of denominators.

For example, if you want to subtract 2(1/3) from 5, denominators are 3 and 1, and LCM is 3.

Step(iii) : Convert whole number to a fraction with same denominator as common denominator.

For example, if LCM is 3 and we want to subtract 2(1/3) from 5, we will convert 5 to fraction 15/3.

Step(iv) : Rewrite each fraction with common denominator.

For example, if we want to subtract 2(1/3) from 5, we rewrite 2(1/3) as 7/3 and 15/3 as 5.

Step(v) : Subtract the fractions.

For example, to subtract 7/3 from 5, we subtract numerators and keep the denominator: 15/3 - 7/3 = 8/3.

For a statement to be true, it must be true in every possible case. The following are the truth values for each statement:

For all r in R, x²+1 > x is true.Vx (x > 1) is also true. Let's look at each statement's truth value. Vr(x²+1 > x) is the first one. Here, V is used as a universal quantifier. For any value of r in the domain of discourse R, the statement must be true. Since we're dealing with a quadratic function here, we can say that for any value of r, the function x²+1 is always greater than x, and the statement is therefore true. Now, let's look at Vx (x > 1). Here, we're using another universal quantifier, Vx. For every value of x in the domain of discourse R, the statement must be true. We know that any value of x that is greater than 1 will satisfy this inequality. As a result, the statement is true for every possible case. In conclusion, the truth values of both statements have been determined. For all r in R, x²+1 > x is true. Vx (x > 1) is also true.

2) The purchase of the car is $24,790.

Step-by-step explanation:

1) 21640*0.02=432.8+250=682.8

15075 0.02301.5+ 250-551.5

682.8+ 551.5-1,234.3

2) 745.8-250-495.8/0.02= 24,790

Step-by-step explanation:

don't guess around, just calculate yourself.

first he sold a car for $15,075.

c(15075) = 250 + 0.02×15075 = $551.50

then he sold another car for $21,640.

c(21640) = 250 + 0.02×21640 = $682.80

his total commission was

$551.50 + $682.80 = $1,234.30

c(p) = 745.80

what was p ?

The probability that exactly 6 patients is 2.0669, and the probability that at least 2 patients is 0.0017.

In large restaurants, an average of 3 out of every 5 customers ask for water with their meal. A random sample of 10 customers was selected. We need to estimate the probability that exactly 6 patients and at least 2 patients. The given situation is a binomial distribution since the experiment has only two outcomes, success or failure.

Here, Success is defined as requesting water with a meal, and failure as not requesting water with a meal. The probability of success is p = 3/5 = 0.6 and the probability of failure is q = 1 - p = 1 - 0.6 = 0.4. Let X be the number of patients requesting water with a meal out of 10 patients selected.

P(X = 6) = 10C6 (0.6) (0.4)⁴

= 210 × 0.31104 × 0.0256

= 2.0669P(X ≥ 2)

= P(X = 2) + P(X = 3) + .... + P(X = 10)P(X ≥ 2)

= 10C2 (0.6)² (0.4)⁸ + 10C3 (0.6)³ (0.4)⁷ + ..... + 10C10 (0.6)¹⁰ (0.4)⁰ P(X ≥ 2)

= 0.0022 + 0.0185 + 0.0881 + 0.2353 + 0.3454 + 0.2508 + 0.0986 + 0.0180 + 0.0016P(X ≥ 2)

= 1 - P(X < 2)P(X < 2) = P(X = 0) + P(X = 1)P(X < 2)

= 10C0 (0.6)⁰ (0.4)¹⁰ + 10C1 (0.6)¹ (0.4)⁹ P(X < 2)

= 0.0001 + 0.0016P(X < 2)

This means that if we were to draw a line perpendicular to the given line at any point, the slope of that line would be 3.

We must first determine the slope of the supplied line in order to determine the slope of a line perpendicular to the line passing through (-3, -1) and (0, -2).

We may determine the slope of the given line by using the slope formula (m = (y2 - y1) / (x2 - x1)) as follows:

m = (-2 - (-1)) / (0 - (-3)) = -1 / 3

The negative reciprocal of -1/3, or 3, would be the slope of a line that was perpendicular to this line.

As a result, a line perpendicular to the line passing between (-3, -1) and (0, -2) will have a slope of 3. This suggests that the slope of the line we would draw if we were to draw it perpendicular to the supplied line at any point would be 3.

You can write the first 4 terms of the sequence by evaluating the 'an' expression for n = 1, 2, 3, 4.

Or, you can recognize the expression describes a sequence with a first term of 42 and a common difference of -4. That is, each term is 4 less than the one before.

The terms you want are ...

Additional comment

The equation for the n-th term of an arithmetic sequence is ...

  an = a1 +d(n -1)

where a1 is the first term, and d is the common difference. Comparing this to the given equation, we see a1 = 42, d = -4.

The binomial probability formula is used to calculate the probability of a specific number of successes in a fixed number of independent trials, where each trial can only result in success or failure. It is used to model situations where there are only two possible outcomes for each trial, and where the trials are independent and identically distributed.

The formula for binomial probability is:

\(P(x) = (n choose x) * p^x * (1 - p)^{n-x}\\\)

where P(x) is the probability of x successes in n trials, p is the probability of success on each trial, (n choose x) is the binomial coefficient which gives the number of ways to choose x successes from n trials, and (1 - p) is the probability of failure on each trial.

On a certain island there are two populations of deer. after years, the numbers of deer in the two populations is zero.

Let x be the population of the first group of deer and y be the population of the second group of deer.

The total population is given by x + y.

The numbers of deer in the two populations are x and y.

Suppose that the population of the first group increases at a rate of a per year, and the population of the second group increases at a rate of b per year.

Then the differential equations that describe the growth of the populations are as follows:

dx/dt = ax

dy/dt = by

The solution to these equations is

\(x(t) = x_0ert\\ y(t) = y_0ert\)

where \(x_0 \:and \: y_0\) are the initial populations of the first and second groups of deer, respectively.

The total population P(t) at time t is given by

\(P(t) = x(t) + y(t) \\P(t) = x_0ert + y_0ert\)

Taking the derivative with respect to t gives the rate of change of P(t) as follows:

\(dP/dt = x_0er + y_0er\)

This is a monotonically increasing function of t.

Therefore, the total population is smallest when the derivative is zero, that is, when er(\(x_0 + y_0\)) = 0.

This occurs when t = 0 or when \(x_0 + y_0 = 0.\)

The probability that a class of 36 has an average midterm mark that is more than 77.83 is 0.0766. This is because the mean of the normally distributed marks is 78 and the standard deviation is 6. Using the standard normal distribution formula, we can calculate the probability that the average mark of 36 students is more than 77.83.

Standard Normal Distribution Formula: P(x > a) = 1 - P(x < a)

P(x > 77.83) = 1 - P(x < 77.83)

P(x > 77.83) = 1 - 0.9234

Step-by-step explanation:

a. The most economical speed for a trip is v = 35 mph. and b. The largest value of M is M = 87.5 miles.

a. To find the most economical speed for a trip, we need to maximize the value of M, which represents the number of miles the automobile can travel on one gallon of gasoline.

Given equation: M = -(1/30)v² + (5/2)v

Take the derivative of M with respect to v using the power rule for derivatives:

dM/dv = -(2/30)v + (5/2)

Set the derivative equal to 0 and solve for v to find the critical point:

-(2/30)v + (5/2) = 0

-(2/30)v = -(5/2)

v = (5/2) * (30/-2)

v = 35

Since v must be less than 70 according to the given range, the most economical speed for the trip is v = 35 mph.

b. To find the largest value of M, we can substitute the given expression for M into the equation and evaluate it for the given range of v, which is v < 0 < 70.

Given equation: M = -(1/30)v² + (5/2)v

Substitute v = 70 into the equation to find the largest value of M:

M = -(1/30)(70)² + (5/2)(70)

M = -4900/30 + 350/2

M = -163.33 + 175

M = 11.67

Therefore, the largest value of M is M = 87.5 miles. (rounded to two decimal places)
