HELP PLEASE A total of 29 bills amounts to $73.00. If there are only $1 and $5 bills, how many of each are there?​

In order for mn to be even, m must be even or n must be an even number.

The relationship between two propositions when the subject and predicate of one are respectively the negation of the predicate and the negation of the subject of the other.

Suppose that the statement “m is even or n is even” is not true. Then both m and n are supposed to be odd. Let’s see if the product of two odd numbers is an even or an odd number:

Let n and m be equal to 2a +1  and 2b + 1 respectively, then their product is:

                 (2a +1) (2b + 1) = 4ab + 2a + 2b + 1

                                       = 2(2ab +a + b) + 1

This shows that the expression 2(2ab +a + b) + 1  is of the form 2n +1,  thus the product is odd. If the product of odd numbers is odd, then mn is not true to be even. Therefore, in order for mn to be even, m must be even or n must be an even number.

The value of h such that the matrix is the augmented matrix of a consistent linear system is 2

For the given matrix to be the augmented matrix of a consistent linear system, we need to check whether the matrix is in row echelon form or not. If the matrix is in row echelon form and the last row is not all zeros, then the linear system is consistent.

We can use elementary row operations to transform the matrix into row echelon form.

\(\left[\begin{array}{ccc}1&h&4\\3&6&8\end{array}\right]\)

R2 <- R2 - 3R1

\(\left[\begin{array}{ccc}1&h&4\\0&6-3h&-4\end{array}\right]\)

The matrix is in row echelon form. Now, we need to check whether the last row is all zeros or not.

If 6-3h = 0, then the last row will be all zeros, which implies that the linear system is inconsistent.

If 6-3h ≠ 0, then the last row will not be all zeros, which implies that the linear system is consistent.

Therefore, we need to solve the equation 6-3h = 0 to determine the value of h that makes the linear system consistent.

6-3h = 0

3h = 6

h = 2

So, the value of h that makes the matrix the augmented matrix of a consistent linear system is h = 2.

Using the binomial distribution, it is found that there is a 0.2415 = 24.15% probability that at least 4 of the people selected will always take medicine as prescribed.

For each person, there are only two possible outcomes, either they take their medicines as prescribed, or they do not. The probability of a person taking their medicine as prescribed is independent of any other person, hence the binomial distribution is used to solve this question.

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

The parameters are:

In this problem:

The probability that at least 4 of the people selected will always take medicine as prescribed is:

\(P(X \geq 4) = P(X = 4) + P(X = 5)\)

In which:

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 4) = C_{5,4}.(0.54)^{4}.(0.46)^{1} = 0.1956\)

\(P(X = 5) = C_{5,5}.(0.54)^{5}.(0.46)^{0} = 0.0459\)

Then:

\(P(X \geq 4) = P(X = 4) + P(X = 5) = 0.1956 + 0.0459 = 0.2415\)

0.2415 = 24.15% probability that at least 4 of the people selected will always take medicine as prescribed.

Answer:

So the width of the rectangle is 20 units.

Step-by-step explanation:

Since the area of the rectangle is 80 square units and the length of one side is 4 units, we can use the formula for the area of a rectangle (A = lw) to find the width of the rectangle. We can set up the equation like this:

A = lw

80 = 4w

w = 20

So the width of the rectangle is 20 units. This means that the vertices of one of the sides of the rectangle that represents the width could be (0,0), (0,20), (20,0), and (20,20). These coordinates assume that the lower left corner of the rectangle is at the origin (0,0). If the rectangle is not at the origin, the coordinates of the vertices would be different. For example, if the lower left corner of the rectangle was at (-5,5), the coordinates of the vertices would be (-5,5), (-5,25), (15,5), and (15,25).

Answer:

Step-by-step explanation:

You want the slope, y-intercept, and equation for a line that passes through the points (2, -2) and (8, 1).

The slope formula is used to find the slope:

  m = (y2 -y1)/(x2 -x1)

  m = (1 -(-2))/(8 -2) = 3/6 = 1/2

The slope-intercept equation can be rearranged to give the y-intercept:

  b = y - mx

  b = 1 -(1/2)(8) = 1 -4 = -3 . . . . . . using (x, y) = (8, 1)

The slope-intercept form equation is ...

  y = mx +b . . . . . . where m is the slope, and b is the y-intercept

Using the found values, the equation is ...

Step-by-step explanation:

The correct statement regarding the inverse function of f(x) = 4x^4 is given as follows:

\(f^{-1}(x) = \pm \left(\frac{x}{4}\right)^{\frac{1}{4}}\); f^(-1)(x) is not a function.

The function in this problem is defined as follows:

f(x) = 4x^4.

To obtain the inverse of a function y = f(x), first the variables y and x are exchanged, as follows:

x = 4y^4.

Isolating the variable y, we have that:

y^4 = (x/4).

The inverse operation of the fourth power is the fourth root, hence:

\(y = \pm \sqrt[4]{\frac{x}{4}}\)

\(f^{-1}(x) = \pm \sqrt[4]{\frac{x}{4}}\)

\(f^{-1}(x) = \pm \left(\frac{x}{4}\right)^{\frac{1}{4}}\)

The plus/minus symbol means that for each input of x, the inverse function gives two outputs, meaning that there are multiple outputs mapped to each input, and thus the inverse is not a function.

This means that the second statement is correct.

Answer:

f(2) = 0

Step-by-step explanation:

Given that f(x) = 3x² - 7x + 4/x ,

We want to find f(2)

To do so, we simply "plug in" or substitute the inputted value (which is 2) into all x's.

So

f(x) = 3x² - 7x + 4/x

==> replace all x's with 2

f(2) = 3(2)² - 7(2) + 4/2

==> evaluate exponent

f(2) = 3(4) - 7(2) + 4/2

==> multiply 3 and 4

f(2) = 12 - 7(2) + 4/2

==> multiply -7 and 2

f(2) = 12 - 14 + 4/2

==> divide 4 by 2

f(2) = 12 - 14 + 2

 The conclusion is that the researcher was correct

Step-by-step explanation:

From the question we are told that

     The sample size is  \(n = 13\)

    The sample mean is  \(\= x = 9.63\)

     The standard deviation is  \(s = 0.585\)

      The significance level is  \(\alpha = 0.05\)

The Null Hypothesis is  \(H_o : \mu = 0\)

The Alternative  Hypothesis  is  \(H_a = \mu < 10\)

The test statistic is  mathematically represented as

          \(t = \frac{\= x - \mu }{\frac{s}{\sqrt{n} } }\)

Substituting values

          \(t = \frac{9.63 - 10 }{\frac{0.585}{\sqrt{13} } }\)

         \(t = - 2.280\)

Now the critical value for \(\alpha\) is  

     \(t_{\alpha } = 1.645\)

This obtained from the critical value table

  So comparing the critical value of alpha and the test value we see that the test value is less than the critical value so the Null Hypothesis is rejected

 The conclusion is that the researcher was correct

The correct answer is C) 9.9 lbs as it is above the upper boundary 6.4865, it is the outlier in this dataset.

An outlier is an observation that is much higher or lower than the other observations in a dataset.

In this case, the weights of the catfish range from 2.7 to 4.8 lbs, with one observation that is much higher at 9.9 lbs.

Therefore, 9.9 lbs is the outlier in this dataset.

To find the outlier in this dataset, we can calculate the interquartile range (IQR).

This is done by first calculating the first quartile (Q1) and third quartile (Q3).

The Q1 for this dataset =3.75

and the Q3= 4.675.

IQR= Q3 - Q1

= 0.925.

We then calculate the lower boundary as Q1 - (1.5 x IQR) = 2.3625.

The upper boundary is Q3 + (1.5 x IQR)= 6.4865.

Since 9.9 lbs is above this upper boundary, it is the outlier in this dataset.

The weight that does not round to 2.46 pounds is C 2.454 pounds.

Step-by-step explanation:

Based on the given information, the weights of the four similar packs of tomatoes are as follows:

Malcolm rounds the weights to the nearest hundredth pound. To round to the nearest hundredth pound, we look at the digit in the hundredths place. If it is 5 or greater, we round up the digit in the tenths place. If it is less than 5, we leave the digit in the tenths place as it is. Therefore, we can obtain the rounded weights as follows:

From the above rounded weights, we see that Pack C rounds to 2.45 pounds and does not round to 2.46 pounds. Therefore, the weight that does not round to 2.46 pounds is C 2.454 pounds.
