Answer:

Mr. Lozano has 9 cabinets more.

Step-by-step explanation:

Mr. Lozano's office has nine rows of filing cabinets with nine cabinets in each row.

So, the total cabinet in Mr. Lozano's office is: \(9 \times 9=81\)

Thus, the total number of cabinets in Mr. Lozano's office is 81.

Mrs. Jackson's office has six rows of cabinets with 12 cabinets in each row.

So, the total cabinet in Mrs. Jackson'soffice is: \(6 \times 12=72\)

Thus, the total number of cabinets in Mrs. Jackson's office is 72.

Now subtract 72 from 81 as Mr. Lozano's office has more cabinets.

\(81-72=9\)

Hence, Mr. Lozano has 9 cabinets more.

The function y=x²+5x-6 has a minimum value. All real numbers are included in the function's domain. The function has a range of y ≤ 12.25, the correct option is (c).

The parabola has a minimum value and widens upwards since the x² term's coefficient is positive.

To find the minimum value, we can use the formula for the x-coordinate of the vertex:

x=-b/2a=-5/(2 × 1)=-2.5.

Plugging this value into the equation, we get

y=(-2.5)²+5(-2.5)-6=-12.25.

Therefore, the function has a minimum value of -12.25.

The function is a polynomial, which means it is defined for all real numbers.

Since the function has a minimum value of -12.25, the range of the function is all real numbers less than or equal to -12.25, i.e., {y ≤ 12.25}.

Hi there!

Linear equations are typically organized in slope-intercept form: \(y=mx+b\) where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Determine the slope (m)

\(m=\frac{y_2-y_1}{x_2-x_1}\) where two points the line passes through are \((x_1,y_1)\) and \((x_2,y_2)\)

Plug in the given points (-3,-1) and (6,2)

\(=\frac{2-(-1)}{6-(-3)}\\=\frac{2+1}{6+3}\\=\frac{3}{9}\\=\frac{1}{3}\)

Therefore, the slope of the line is \(\frac{1}{3}\). Plug this into \(y=mx+b\):

\(y=\frac{1}{3}x+b\)

2) Determine the y-intercept (b)

\(y=\frac{1}{3}x+b\)

Plug in one of the given points and solve for b

\(2=\frac{1}{3}(6)+b\\2=2+b\)

Subtract 2 from both sides to isolate b

\(2-2=2+b-2\\0=b\)

Therefore, the y-intercept is equal to 0. Plug this back into \(y=\frac{1}{3}x+b\):

\(y=\frac{1}{3}x+0\\y=\frac{1}{3}x\)

The 90% confidence interval for the difference in the population means is -2.51 to 0.31

From the question, we have the following parameters that can be used in our computation:

xˉ₁ = −17.1

s₁² = 8.4

n₁ = 22

​xˉ₂ = −16.0

s₂² = 8.7

n₂ = 24

Calculate the pooled variance using

P = (df₁ * s₁² + df₂ * s₂²)/df

Where

df₁ = 22 - 1 = 21

df₂ = 24 - 1 = 23

df = 22 + 24 - 2 = 44

So, we have

P = (21 * 8.4 + 23 * 8.7)/44

P = 8.56

Also, we have the standard error to be

SE = √(P/n₁ + P/n₂)

So, we have

SE = √(8.56/22 + 8.56/24)

SE = 0.86

The z score at 90% CI is 1.645, and the CI is calculated as

CI =  (x₁ - x₂) ± z * SE

So, we have

CI = (-17.1 + 16.0) ± 1.645 * 0.86

This gives

CI = -1.1 ± 1.41

Expand and evaluate

CI = (-2.51, 0.31)

Hence, the confidence interval is -2.51 to 0.31

Answer:

-5

Step-by-step explanation:

We can see two points that the line intersects:

(0,2) and (1,-3)

‘From that we can find the slope:

\(\frac{y_2-y_1}{x_2-x_1} = \frac{-3-2}{1-0} = \frac{-5}{1} = -5\)

So, A.

:)

Answer:

-5

Step-by-step explanation:

Fast and loose: it's a negative number, since the line is decreasing, and it's decreasing faster than the diagonal of the II-IV quadrant (y=-x) so it's a number less than -1. Slope it's thus -5 or close to it.

More rigorous: start counting the squares. A slope of \(\frac ab\) tells you that every time you move vertically by a squares, you moved horizontally by b squares. Here to advance from 0 to 1 you went down from 2 to -3, ie you subtracted 5. Slope is -5

Answer:

The slope is undefined and there is no y- intercept

Step-by-step explanation:

The line is equivelent to x=5

This is a vertical line so the slope is undefined and there is no y- intercept

Answer:

Slope: 0

Y-intercept: 5

Step-by-step explanation:

First, you need to move the equation into slope-intercept form.

Divide both sides by 3.

x = 5

Since there is no number to the right of the y - intercept, we just assume that the slope is 0.

The percent of scores with the indicated ranges found using their z-scores and the z-table are as follows;

a) The percentage of scores less than 40 = 0.272%

b) Percentage of scores that are at least 72 = 21.77%

c) The percentage of scores that are between 60 and 85 = 69.905%

A z-score is an indication of the location of a score on the normal distribution curve.

The distribution of the scores on the exam = Normal distribution

The mean of the scores, μ = 65

The standard deviation, σ = 9

a) The z-score can be found by using the formula;

\(z = \dfrac{x - \mu}{\sigma}\)

Which indicates that when x = 40 we get;

\(z = \dfrac{40 - 65}{9}\approx -2.\overline 7\)

b) The percentage of scores that are at least 72, consists of scores that are from 72 and above;

The z-score of 72 is found as follows;

\(z = \dfrac{72 - 65}{9} =0.\overline 7\)

From the z-score table, we get;

p(z ≥ 0.\(\overline 7\)) = 1 - p(z ≤ 0.\(\overline 7\))  = 1 - 0.78230 = 0.2177

c) The percentage of scares that are between 60 and 80 is found as follows;

The required percentage is; p(60 ≤ x ≤ 85)

The z-score of 60 is;  \(z = \dfrac{60 - 65}{9} = -0.\overline 5\)

The values to the left of the z-score for 60 from the z-table is therefore p(z ≤ -0.\(\overline 5\)) = 0.28774

The z-score of 85 is;  \(z = \dfrac{85 - 65}{9} = 2.\overline 2\)

From the z-table, we get p(z ≤ 2.\(\overline 2\)) = 0.98679

in an election debate, two candidates for governor are debating about whether to raise the general sales tax from 5 to 7 percent, so candidate a assumes that the price effect would be larger than the quantity effect.

When a tax is added on a good or service at the point of sale and is financed by the client, it is known as general sales tax. The store is then obligated to transmit, or remit, the tax to the government.

Candidate a contends that revenue will rise along with the sales tax as it rises from 5 to 7 percent. This suggests that the price impact is greater than the quantity effect since, when the tax is raised, the price would rise and the quantity would fall. As a result, the tax revenue would only rise if the price effect is more than the quantity effect.

Additionally, Candidate b claims that the tax will harm consumers and merchants, slow the economy, and reduce tax revenue. However, this claim can only be supported if the quantity effect outweighs the price effect.

Candidate a assumes that the price effect would be larger than the quantity effect.

The Weighted Average Cost of Capital (WACC) for Snuggly Baby Corp. is calculated based on the company's capital structure, including common equity, preferred equity, and bonds. The WACC is influenced by the expected returns and prices of these securities.

To calculate the WACC, we need to determine the proportion of each component in the capital structure and multiply it by its respective cost of capital.

For Snuggly Baby Corp., the capital structure consists of 6,130,000 shares of common equity, 1,006,000 shares of preferred equity, and 81,400 bonds.

The cost of common equity is calculated using the expected return and the price of the shares. Similarly, the cost of preferred equity is calculated using the expected return and the price of the preferred shares. The cost of debt, represented by the bonds, is calculated using the yield-to-maturity.

Once we have the costs of each component, we multiply them by their respective proportions in the capital structure and sum them up to determine the overall WACC. Please note that to provide an accurate calculation of the WACC, additional information is required, such as the market value of each component and the weights assigned to them in the capital structure. Without this information, it is not possible to provide an exact WACC calculation.

To find the exact length of the curve defined by the parametric equations x = 5t^2 and y = 3t^3, where 0 ≤ t ≤ 3, we can use the arc length formula for parametric curves.

The arc length formula for a parametric curve defined by x = f(t) and y = g(t) over the interval [a, b] is given by:

L = ∫[a,b] √[ (dx/dt)^2 + (dy/dt)^2 ] dt

In this case, we have x = 5t^2 and y = 3t^3, with the parameter t ranging from 0 to 3.

First, we need to find the derivatives of x and y with respect to t:

dx/dt = d/dt (5t^2) = 10t

dy/dt = d/dt (3t^3) = 9t^2

Next, we substitute these derivatives into the arc length formula:

L = ∫[0,3] √[ (10t)^2 + (9t^2)^2 ] dt

L = ∫[0,3] √(100t^2 + 81t^4) dt

Now, we can integrate the expression inside the square root with respect to t:

L = ∫[0,3] √(100t^2 + 81t^4) dt

L = ∫[0,3] t√(100 + 81t^2) dt

Unfortunately, this integral does not have a simple closed-form solution. We would need to evaluate it numerically using numerical integration techniques or computer software.

So, the exact length of the curve cannot be determined algebraically. However, it can be approximated using numerical methods.
