Deanna bought the poster shown below for her wall. Note: Figure not drawn to scale If a = 11 cm, b = 25 cm, c = 16 cm, and d = 19 cm, what is the area of the poster?

Option (b) Measure the heights of a random sample of 10 6-year-old girls would produce a narrower interval than the 90% confidence interval computed above. Options (a), (c), and (d) would not produce narrower intervals, and the correct answer is (e) None of the above.

To understand which option would produce a narrower interval than the 90% confidence interval computed above, we need to consider the factors that affect the width of the confidence interval. These factors include the sample size and the chosen confidence level. (a) Option (a) suggests measuring the heights of a random sample of 50 6-year-old girls. A larger sample size tends to produce narrower confidence intervals, so this option would likely result in a wider interval than the one computed with a sample size of 18.

(b) Option (b) suggests measuring the heights of a random sample of 10 6-year-old girls. A smaller sample size results in wider confidence intervals due to increased uncertainty, so this option would likely produce a narrower interval compared to the original 90% confidence interval. (c) Option (c) suggests computing a 95% confidence interval rather than a 90% confidence interval. Increasing the confidence level leads to wider intervals to accommodate the increased level of certainty, so this option would result in a wider interval.

(d) Option (d) suggests computing a 99% confidence interval rather than a 90% confidence interval. Similarly, increasing the confidence level to 99% increases the level of certainty and widens the interval. Based on the explanations above, option (b) Measure the heights of a random sample of 10 6-year-old girls is the correct choice as it would produce a narrower interval compared to the 90% confidence interval computed above. Therefore, the answer is (e) None of the above.

Answer:

\(\boxed {\tt 13.75 \ yards}\)

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean Theorem.

\(a^2+b^2=c^2\)

where \(a\) and \(b\) are the legs and \(c\) is the hypotenuse.

One of the legs is 10 yards, and the other is unknown. The hypotenuse is 17 yards, because it is the longest side.

\(a= 10 \ yd\\b=b\\c= 17 \ yd\)

Substitute the values into the formula.

\((10 \ yd)^2+b^2=(17 \ yd)^2\)

Evaluate the exponents.

\(100 \ yd^2+b^2= (17 \ yd)^2\)

\(100 \ yd^2+b^2= 289 \ yd^2\)

Now, solve for b. First, subtract 100 yards squared from both sides of the equation.

\(100 \ yd^2-100 \ yd^2+b^2= 289 \ yd^2- 100 \ yd^2\)

\(b^2=289\ yd^2-100 \ yd^2\)

\(b^2=189 \ yd^2\)

Finally, take the square root of each side of the equation.

\(\sqrt{b^2} =\sqrt{189\ yd^2}\)

\(b=\sqrt{189 \ yd^2}\)

\(b=13.7477271 \ yd\)

Round to the nearest hundredth. The 7 in the thousandth place tells us to round the 4 to a 5.

\(b \approx 13.75 \ yd\)

The other side of the garden is about 13.75 yards long.

Answer:

Step-by-step explanation:

3x - 9y = 9 → (1)

- 2x +2y = 8 ( subtract 2y from both sides )

- 2x = - 2y + 8 ( divide through by - 2 )

x = y - 4

substitute x = y - 4 into (1)

3(y - 4) - 9y = 9

3y - 12 - 9y = 9

- 6y - 12 = 9 ( add 12 to both sides )

- 6y = 21 ( divide both sides by - 6 )

y = \(\frac{21}{-6}\) = - \(\frac{7}{2}\)

The hospital must cut the number of overtime hours by approximately 2.91% in order to stay within budget.

To determine the required percentage reduction in overtime hours, we need to consider the impact of the nurses' hourly rate increase and the limited budget increase for overtime wages.

Let's assume the current budget for nurses' overtime wages is denoted by B, and the total number of overtime hours worked is denoted by H. The current overtime rate per hour is R.

With the 5% hourly rate increase, the new overtime rate per hour becomes 1.05R. Considering the limited budget increase of 3%, the new budget for overtime wages is 1.03B.

To calculate the required percentage reduction in overtime hours, we can set up the following equation:

(1.05R) * (1 - x) * H = 1.03B

where x represents the required percentage reduction in overtime hours.

Simplifying the equation, we have:

(1 - x) * H = (1.03B) / (1.05R)

Now, let's solve for x:

1 - x = (1.03B) / (1.05R * H)

x = 1 - [(1.03B) / (1.05R * H)]

Here, we can see that the required percentage reduction in overtime hours, represented by x, depends on the values of B, R, and H.

It's important to note that without knowing the specific values of B, R, and H, we cannot calculate the exact percentage reduction. However, based on the provided information, we can determine the maximum percentage reduction that the hospital must make to stay within budget.

By assuming that B, R, and H are constant, we can use the given constraints to calculate an approximate percentage reduction. Based on the constraints of a 3% budget increase and a 5% hourly rate increase, the hospital would need to reduce the number of overtime hours by approximately 2.91% to maintain a balanced budget.

Please keep in mind that this approximation may vary depending on the specific values of B, R, and H.

The solution of the piecewise function at the given values of the independent variable g(0) is 5, g(-7) is 12 and g(2) is 7.

This is an example of a piecewise function, which is a function composed of two or more parts, each part being defined by a separate equation.

In this function, the first part is defined as g(x) = x+5 if x >= -5, and the second part is defined as g(x) = -(x+5) if x < -5.

To evaluate the function at the given values of the independent variable, we can simply substitute the values into the appropriate equation.

At x = 0,

=> g(0) = 0+5 = 5.

At x = -7,

=> g(-7) = -(-7+5) = 12.

And at x = 2,

=> g(2) = 2+5 = 7.

Therefore, the values of the function are 5, 12, and 7 respectively

The value of c for the intersecting secants is derived to be equal to 2 cm

The intersecting secant theorem, also known as the secant-secant theorem, states that when two secant lines intersect outside a circle, the product of the length of one secant segment and its external segment is equal to the product of the length of the other secant segment and its external segment.

c × 18 cm = 3 cm × 12 cm

c18 cm = 36 cm²

c = 36 cm²/18 cm

c = 2 cm

y=-x-8

Step-by-step explanation:

Hope this helps!

Answer:

y = -x - 8

Step-by-step explanation:

2x + 2y = -16 is in standard form, but we want it in slope-intercept form, which looks like y = mx + b, with m being the slope and b being the y-intercept.

So, first, we'll try to isolate our y on one side. I'll do this by subtracting 2x from both sides.

2x + 2y = -16

2y = -2x - 16

Then, I'll divide everything by 2 to take away the 2 before the y.

y = -x - 8

Does that look like slope-intercept form (y = mx + b)? Yes! So we can say that this is the answer to the question.

If you need clarification on anything, let me know.

So the slope of the scenario is $28 per hour, which indicates that the expense of the tour increases by $28 for every extra hour spent on it.

The slope of a line indicates its steepness. Slope is computed mathematically as "rise over run" (change in y divided by change in x). The slope-intercept form of an equation occurs when the equation of a line is stated in the form y = mx + b. The slope of the line is given by m. And b is the value of b in the y-intercept point (0, b). For example, the slope of the equation y = 3x - 7 is 3, while the y-intercept is (0, 7).

Here,

In this situation, the slope represents the rate of change in the cost of the tour with respect to the time spent on the tour. The slope of the situation can be calculated as the change in cost divided by the change in time.

Since the one-time fee is a fixed cost, it does not change with respect to the time spent on the tour. Therefore, the slope can be calculated as the rate of change in the cost due to the hourly fee of $28.

The slope can be represented as:

slope = Δcost/Δtime = $28/hour

So, the slope of the situation is $28 per hour, which means that for every additional hour spent on the tour, the cost of the tour increases by $28.

By using Chebyshev's Inequality with K=3, we can determine that at least 88.89% of the days had temperatures between "F and "F, where "F represents the mean temperature of 76.4°F.

Chebyshev's Inequality provides a lower bound on the proportion of data that falls within a certain number of standard deviations from the mean. In this case, K=3 means that we are considering a range of three standard deviations from the mean.

The inequality states that for any dataset, the proportion of data falling within K standard deviations of the mean is at least 1 - (1/K^2). So, for K=3, we have 1 - (1/3^2) = 1 - (1/9) = 8/9 ≈ 0.8889. Therefore, at least 88.89% of the data falls within three standard deviations of the mean.

In the context of the temperature data, we can conclude that at least 88.89% of the days had temperatures between the mean temperature of 76.4°F minus three standard deviations (76.4 - 3 * 7.3) and the mean temperature plus three standard deviations (76.4 + 3 * 7.3). This range represents a relatively high proportion of the dataset, indicating that the temperature observations are fairly concentrated around the mean with limited extreme values.

The differential equation is \(5y^n+30y=0\). The initial conditions are y(0) = 7 and y’(0) = 5.

The differential equation is:\(5y^n+30y=0\). First, we solve for n which is the exponent of y.
We get:n = -1When n = -1, the differential equation becomes:5(1/y)+30y=0
Rearranging terms, we get:5(1/y) = -30y
Dividing both sides by 5y, we have:-1/y² = -6
This yields: y(t) =  \(\sqrt{6}\)/t The initial conditions are:y(0) = 7 and y’(0) = 5
We can now apply the first initial condition to find the value of C_1.C_1 = 7/ \(\sqrt{6}\)
When we apply the second initial condition to solve for C_2, we get: C_2 = 5 \(\sqrt{6}\)
Now, we can write the final answer: y(t) = 7cos(t \(\sqrt{6}\)) + 5 \sqrt{6}sin(t \(\sqrt{6}\))
Thus, the function of y as a function of t is y(t) = 7cos(t \(\sqrt{6}\)) + 5 \sqrt{6}sin(t \(\sqrt{6}\)) which is generated by the differential equation \(5y^n+30y=0\)  and initial conditions y(0) = 7 and y’(0) = 5.
