Answer:

$34.51

Step-by-step explanation:

To find 19% of 29, you first want to change the 19% to a decimal.

19% to a decimal is 0.19

Then you multiply the 0.19 by 29

29•0.19= 5.51

Now just add the 5.51 to the 29 to get the total

5.51+29=$34.51

The equation of the line perpendicular to x - 4y = 8 and passing through (1,7) is y = -4x + 11

To find the equation of a line perpendicular to x - 4y = 8 and passing through the point (1,7), we need to determine the slope of the original line, which we can rewrite in slope-intercept form as

y = (1/4)x - 2.

Since the slope of the line perpendicular to this line is the negative reciprocal of 1/4, it must be -4. Using the point-slope form of the equation of a line,

y - y1 = m(x - x1),

we can plug in the point (1,7) and the slope of -4 to get the equation

y - 7 = -4(x - 1).

This can be simplified to y = -4x + 11, which is the equation of the line perpendicular to x - 4y = 8 and passing through (1,7).

The length of the line segment with points (-5, 5) (3, -1) is 10 units

The length of line in an ordered pair is calculated using the formula

d = √{(x₂ - x₁)² + (y₂ - y₁)²}

where

d = distance between the points

x₂ and x₁ = points in x coordinates

y₂ and y₁ = points in y coordinates

distance between points  (-5, 5) and (3, -1) is calculated as follows

d = √{(x₂ - x₁)² + (y₂ - y₁)²}

d =√{(-5 - 3)² + (5 - -1)²}

d =√{64 + 36}

d = √100

The margin of error is a measure of the degree of uncertainty associated with the point estimate of a population parameter. Confidence intervals are constructed to estimate the true value of a population parameter with a certain level of confidence.

The margin of error and the width of the confidence interval are related, in that a larger margin of error implies a wider confidence interval.

When constructing a one-sample z-confidence interval to estimate the population proportion, the margin of error increases as the sample size increases. This is because larger sample sizes provide more information about the population and, as a result, the estimate becomes more precise. Conversely, as the sample size decreases, the margin of error increases, making the estimate less precise.

The margin of error also increases as the population proportion approaches 0.50. This is because when p=0.50, the population is evenly split between the two possible outcomes. As a result, more variability is expected in the sample proportions, leading to a larger margin of error.

Finally, the margin of error decreases as the confidence level (1-a) increases. This is because a higher confidence level requires a wider interval to account for the additional uncertainty associated with a higher level of confidence. In conclusion, the margin of error in one-sample z confidence intervals is affected by sample size, population proportion, and confidence level.

It's the fourth one y=-1/6x+2/3

Step-by-step explanation:

An exponential function that best represents the value of the computer in months is V(t) = 1500(0.9763)^m.

In Mathematics, an exponential function simply refers to a mathematical function whose values are generated by a constant that is raised to the power of the argument. Mathematically, an exponential function can be modeled by using this equation:

f(x) = ab^t

Where:

From the information provided, the value, V, of a computer is modeled by this function:

V(t) = 1500(0.75)^t

Where:

t represents the number of years since the computer was purchased.

Note: one (1) year is equal to 12 months (m).

Now, we can remodel the value of this computer in months:

V(t) = 1500(0.75)^m/t

V(t) = 1500(0.75)^m/12

V(t) = 1500(0.75^{1/12})^m

V(t) = 1500(0.9763)^m

The correct option is D)\(2+\sqrt{6z} /4-6z\) .The choice is equivalent to the given fraction when x is an appropriate value is \(2+\sqrt{6z} /4-6z\)

Let's rationalize the denominator of the given fraction as shown below:

\($4 - \sqrt{6z} = \frac{(4 - \sqrt{6z}) (\overline{4 + \sqrt{6z}})}{(4 - \sqrt{6z}) (\overline{4 + \sqrt{6z}})}$\)

Here, the denominator is of the form\($(a-b)(a+b)$\), which can be written as \($a^2 - b^2$\).

Therefore, the above expression can be simplified as:

\(\[\frac{(4 - \sqrt{6z}) (\overline{4 + \sqrt{6z}})}{(4 - \sqrt{6z}) (\overline{4 + \sqrt{6z}})} \\= \frac{(4^2 - \sqrt{(6z)^2})}{(4 - \sqrt{6z}) (\overline{4 + \sqrt{6z}})}\\\\= \frac{16 - 6z}{16 - (6z)}\\\\= \frac{16 - 6z}{10} = \frac{8-3z}{5}\]\)

Therefore, we can see that choice D) \(2+\sqrt{6z} /4-6z\) is equivalent to the given fraction when x is an appropriate value.

Answer:

The length of Bob's snake = x = 80 inches

The length of Mary's snake = y = 30 inches

Step-by-step explanation:

Let the length of Bob's snake = x

the length of Mary's snake = y

From the above question:

Bob's pet snake is 10 inches shorter than three times the length of Mary's pet snake.

x = 3 × y - 10

x = 3y - 10

If both their snakes laid together end to end measure 110 inches, how long is Bob's snake?

x + y = 110 inches

Substance 3y - 10 for x

3y - 10 + y = 110

Add 10 to both sides of the Equation

3y + y -10 + 10 = 110 + 10

4y = 120

y = 120/4

y = 30 inches

x + y = 110 inches

x + 30 inches = 110 inches

x = 110 inches - 30 inches

x = 80 inches

To compute a basis of the eigen space corresponding to eigen value -2, we need to find the null space of the matrix A + 2I, where A is the 3x3 matrix and I is the identity matrix.

The null space will give us the basis vectors of the eigen space

To find the eigen space corresponding to the eigen value -2, we start by constructing the matrix A + 2I, where A is the given 3x3 matrix and I is the 3x3 identity matrix. Next, we solve the homogeneous system of linear equations (A + 2I)x = 0, where x is a vector. The solutions to this system form the null space of the matrix A + 2I.

By finding a basis for this null space, we can obtain the basis vectors of the eigen space corresponding to the eigen value -2.

Sydney can row a canoe at a speed of 5 mph in still water.

Let x represent Sydney's speed in still water. When rowing upriver, her effective speed will be (x - 2) mph because she's going against the current, which flows at 2 mph. When rowing downriver, her effective speed will be (x + 2) mph, since she's going with the current.

According to the problem, the time it takes her to row 6 miles upriver is the same as the time it takes her to row 14 miles downriver. We can set up the equation using the formula time = distance / speed:

6 / (x - 2) = 14 / (x + 2)

To solve for x, first cross-multiply:

6(x + 2) = 14(x - 2)

Expand:

6x + 12 = 14x - 28

Now, rearrange and solve for x:

12 + 28 = 14x - 6x

40 = 8x

x = 5

So, Sydney can row a canoe at a speed of 5 mph in still water.
