The solutions for the inequality y ≤ 2/7x + 1 exist in quadrants I, III, and IV.

What is the quadrants?

The quadrants are the four regions that result from dividing a Cartesian coordinate plane into four parts using two perpendicular lines, the x-axis and y-axis.

The inequality y ≤ 2/7x + 1 represents a line on the x-y plane. The solutions for the inequality are the points on the plane that lie below or on the line. In a standard Cartesian coordinate system with x-axis and y-axis, the x-axis separates the plane into two parts: the upper half-plane (quadrant I) and the lower half-plane (quadrants III and IV). The y-axis separates the plane into two more parts: the right half-plane (quadrants I and IV) and the left half-plane (quadrants II and III).

So the solutions for the inequality y ≤ 2/7x + 1 lie in the region of the x-y plane that is in the lower half-plane (quadrants III and IV) and the right half-plane (quadrant I). Therefore, the solutions exist in quadrants I, III, and IV.

Step-by-step explanation:

What you are testing is a distribution of means, because you have a sample of eleven individuals (N=11), a population mean, and the population variance. Basically, the problem is asking: what is the likelihood that the sample mean (153.45 lbs) could have been obtained from a population where (M=149) if the null hypothesis is true?

p1: 15 year old boys with a mean weight of 153.45 lbs from City "Unknown".

p2: 15 year old boys with a mean weight of 149.00 lbs from the population.

H1: The sample of boys from City "Unknown" was not drawn from a population where the average weight of 15 year old boys = 149lbs.

H0: The sample of boys from City "Unknown" was drawn from a population where the average weight of 15 year old boys = 149lbs.

Mean = 149 [μM = μ = 149]

Variance = 16.2squared/11 = 262.44/11 = 23.86 [σM2 = σ2/N]

Standard Deviation = 4.88 [σM = √σM2 = √(σ2/N)]

Shape = normal

Using .01 level of significance for a two-tailed test, the cutoff sample score is +/- 2.575

Z = (M-µ) / σM = (153.45 - 149) / 4.88 = .91

.91 < 2.575

σM or the Standard Error of the Mean is 4.88 so...

for 99% confidence interval,

lower limit = 153.45 + (-2.575)(4.88) = 140.88

upper limit = 153.45 + (2.575)(4.88) = 166.02

the 99% confidence interval = 140.88 — 166.02 (lbs)

the population mean (µ=149.00) is included in the interval, which confirms results of Z test.

Conclusion: retain null, there is <.01 probability that the sample from City "Unknown" was drawn from a population where the mean weight is NOT = 149.00lbs.

Answer:-

   ∴x−3y−4z=0

Explanation:

First we rearrange the equation of the surface into the form f(x,y,z)=0

   x2+2z2=y2

   ∴x2−y2+2z2=0

And so we have our function:

   f(x,y,z)=x2−y2+2z2

In order to find the normal at any particular point in vector space we use the Del, or gradient operator:

   ∇f(x,y,z)=∂f∂xˆi+∂f∂yˆj+∂f∂zˆk

remember when partially differentiating that we differentiate wrt the variable in question whilst treating the other variables as constant. And so:

   ∇f=(∂∂x(x2−y2+2z2))ˆi+

                    (∂∂y(x2−y2+2z2))ˆj+

                    (∂∂z(x2−y2+2z2))ˆk

      =2xˆi−2yˆj+4zˆk

So for the particular point (1,3,−2) the normal vector to the surface is given by:

   ∇f(1,3,−2)=2ˆi−6ˆj−8ˆk

So the tangent plane to the surface x2+2z2=y2 has this normal vector and it also passes though the point (1,3,−2). It will therefore have a vector equation of the form:

   →r⋅→n=→a⋅→n

Where →r=⎛⎜⎝xyz⎞⎟⎠; →n=⎛⎜⎝2−6−8⎞⎟⎠, is the normal vector and a is any point in the plane

Hence, the tangent plane equation is:

   ⎛⎜⎝xyz⎞⎟⎠⋅⎛⎜⎝2−6−8⎞⎟⎠=⎛⎜⎝13−2⎞⎟⎠⋅⎛⎜⎝2−6−8⎞⎟⎠

   ∴(x)(2)+(y)(−6)+(z)(−2)=(1)(2)+(3)(−6)+(−2)(−8)

   ∴2x−6y−8z=2−18+16

   ∴2x−6y−8z=0

   ∴x−3y−4z=0

The area of land the charity planted was 17000 m². The charity met its target

An equation is an expression that is used to show how numbers and variables are related using mathematical operators

1 km = 1000 m

1 km² = 1000000 m²

An environmental charity set a target to plant trees on 9000 m² of land in September.

In September, it planted trees on 0.017 km² of land. Hence:

Area of land planted = 0.017 km² * 1000000 m² per km² = 17000 m²

17000 m² is greater than 9000m². The charity met its target

The p-value for a one-tailed test with 24 degrees of freedom and a t-value of 3.5 is less than 0.01 and  an effect size of 0.57 indicates that alcohol consumption has a significant impact on reaction time, and the magnitude of the effect is moderate to large.

To determine if the data is sufficient to conclude that alcohol has a significant effect on reaction time, we need to conduct a hypothesis test. We can use a two-tailed test because we are not sure if alcohol will increase or decrease the reaction time.

The null hypothesis (H0) is that the mean reaction time is equal to the regular population average of 400 msec. The alternative hypothesis (Ha) is that the mean reaction time is not equal to 400 msec due to alcohol consumption.

With a significance level of α = 0.1, we can use a t-test to test the hypotheses. The formula for the t-value is:

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

Where M is the sample mean, μ is the population mean, s is the sample standard deviation, and n is the sample size.

Plugging in the values from the problem, we get:

\(t = \frac{(422 - 400)}{(40 \sqrt{25})} = 3.5\)

The degrees of freedom for this test is n-1 = 24. Using a t-table or calculator, we find that the p-value for a two-tailed test with 24 degrees of freedom and a t-value of 3.5 is less than 0.01.

Therefore, we reject the null hypothesis and conclude that alcohol consumption has a significant effect on reaction time.

To determine if the data provides evidence that alcohol significantly increased (slowed) reaction time, we can use a one-tailed test because we are only interested in whether alcohol increases reaction time.

The null hypothesis (\(H_0\)) is that the mean reaction time is equal to the regular population average of 400 msec. The alternative hypothesis (Ha) is that the mean reaction time is greater than 400 msec due to alcohol consumption.

With a significance level of α = 0.05, we can use a t-test to test the hypotheses.

Using the same formula as before, we get:

\(t = \frac{(422 - 400)}{40 \sqrt{25} }=3.5\)

The p-value for a one-tailed test with 24 degrees of freedom and a t-value of 3.5 is less than 0.01.

Therefore, we reject the null hypothesis and conclude that the data provides evidence that alcohol significantly increased (slowed) reaction time.

Cohen's d is a measure of effect size that allows us to determine the magnitude of the difference between two means in terms of standard deviation units. Cohen's d is calculated by taking the difference between the two means and dividing it by the pooled standard deviation.

The formula for Cohen's d is:

\(d = \frac{M_1 - M_2}{s}\)

Where \(M_1\) and \(M_2\) are the means of the two groups being compared, and s is the pooled standard deviation.

In this case, we can use the regular population average of 400 msec as the comparison group, and the sample mean of 422 msec as the experimental group. The pooled standard deviation can be calculated using the formula:

\(s=\sqrt{\frac{((n_1-1)s_1^2 + (n_2-1)s_2^2)}{ (n_1 + n_2 - 2)} }\)

Where \(s_1\) and \(s_2\) are the standard deviations of the two groups, and \(n_1\)and \(n_2\) are the sample sizes.

Using the values from the problem, we get:

\(s=\sqrt{\frac{((25-1)40^2 + (1-1)0^2)}{ (25 + 1 - 2)} } = 38.91\)

Plugging in the values for\(M_1\), \(M_2\), and s, we get:

d = (422 - 400) / 38.91 = 0.57

The effect size (Cohen's d) of 0.57 suggests a moderate to large effect of alcohol on reaction time. According to Cohen's guidelines, an effect size of 0.2 is considered small, 0.5 is considered medium, and 0.8 or higher is considered large.

Therefore, an effect size of 0.57 indicates that alcohol consumption has a significant impact on reaction time, and the magnitude of the effect is moderate to large.

It is worth noting that Cohen's d only provides an estimate of effect size, and other factors such as the context of the study and the specific population being studied may influence the interpretation of the effect size. Nevertheless, Cohen's d is a widely used measure of effect size that allows for meaningful comparisons across studies and different variables.

The point on the curve where the tangent line is parallel to the plane is (-2sin(arccos(-a/2)), 2cos(arcsin(-b/2)), c).

To find the point on the curve r(t) = (-2sin(t),2cos(t),e^t) where the tangent line is parallel to the plane, we need to find the derivative of the curve and set it equal to the normal vector of the plane.

The derivative of the curve r(t) is:

r'(t) = (-2cos(t), -2sin(t), e^t)

The normal vector of the plane is (a,b,c).

To find the point where the tangent line is parallel to the plane, we need to set the derivative equal to the normal vector:

-2cos(t) = a

-2sin(t) = b

e^t = c

Solving for t, we get:

t = arccos(-a/2)

t = arcsin(-b/2)

t = ln(c)

Plugging these values of t back into the original equation for the curve, we can find the point on the curve where the tangent line is parallel to the plane:

x = -2sin(arccos(-a/2))

y = 2cos(arcsin(-b/2))

z = e^(ln(c))

So the point on the curve where the tangent line is parallel to the plane is (-2sin(arccos(-a/2)), 2cos(arcsin(-b/2)), c).

The end of the long hand of the clock travels about 78.54 inches (25π) in 2 1/2 hours.

Clock can be defined as a machine in which a device that performs regular movements in equal intervals of time is linked to a counting mechanism that records the number of movements

The long hand of the clock completes one full revolution in 12 hours. Therefore, in one hour, it travels a distance equal to the circumference of a circle with a radius of 5 inches, which is given by 2πr = 2π(5) = 10π inches.

In 2 1/2 hours, the long hand of the clock travels a distance equal to (2 1/2) x 10π = 25π inches.

So, the end of the long hand of the clock travels about 78.54 inches (25π) in 2 1/2 hours.
