Answer:

46 of the total vehicles are minivans

Step-by-step explanation:

Let the number of minivans be x

and the number of other types of vehicles be y

From the question,

Carla noticed that for every 2 minivans, there were 5 other types of vehicles.

This means the ratio of minivans to other types of vehicles is 2:5.

Therefore,

x:y = 2:5

We can then write that

x/y = 2/5

∴ 5x = 2y ...... (1)

Also from the question,

There are 161 total vehicles in the parking lot

That is

x + y = 161 ...... (2)

From equation (2), we can write that

y = 161 - x

Put this into equation (1)

5x = 2y

Then

5x = 2(161-x)

5x = 322 -2x

5x+2x = 322

7x = 322

x = 322/7

x = 46

Since x represent the number of minivans

Hence, 46 of the total vehicles are minivans.

The answer is 72

First you find E=180-130=50

Then you add all the angles and subtract from 360

102+100+50=252

360-252=108

then you do 180-108=72

Answer:

72 degrees.

Step-by-step explanation:

The first step would be finding E. We know that a straight line would be 180 degrees. Therefore, we would subtract 180-130=50.

100+102+50+b=360

252+b=360

-252   -252

b=108

Then we would subtract 180-108=72.

Therefore, because it is the angle we are looking for.

Your answer would be the measure of angle ABC is 72 degrees.

Answer:

The prism is 3 by 3 by 1.5.

Step-by-step explanation:

The prism has a length x and a width x. Since it is a square at the base both length and width are the same amount x. The height is "half the length of one edge of the base". Since the base is x, this makes it 1/2x.

The volume's prism is found using V = l*w*h. Substitute and simplify.

13.5 = x*x*1/2x

13.5 = 1/2 x^3

27 = x^3

Step-by-step explanation:

By using circumference of circle, we find that In one slice of pizza you will get about 8 olive pieces from Mario's Pizzeria.

The circumference of circle of a 20-inch diameter pizza can be calculated as follows:

Circumference = π × diameter

Circumference = 3.14 × 20

Circumference = 62.8 inches

If there is at least one olive piece per inch of crust, then there will be 62.8 olive pieces on the outer crust of the entire pizza.

If the pizza is cut into eight slices, each slice will have 1/8th of the total circumference of the pizza. Therefore, each slice will have:

62.8 inches ÷ 8 slices = 7.85 inches of outer crust

Since there is at least one olive piece per inch of crust, each slice will have approximately 8 olive pieces on the outer crust.

Therefore, you can expect to get about 8 olive pieces in one slice of pizza from Mario's Pizzeria.

To determine a rejection region for a test at level α using the fact that the sum of independent Poisson random variables follows a Poisson distribution, we calculate the critical values based on the desired significance level α and compare them with the observed sum of Poisson variables.

To determine a rejection region for a test at level α using the fact that the sum of independent Poisson random variables follows a Poisson distribution, we can follow these steps:

Specify the null and alternative hypotheses: Determine the null hypothesis (H0) and the alternative hypothesis (Ha) for the statistical test. These hypotheses should be stated in terms of the parameters being tested.

Choose the significance level (α): The significance level α represents the maximum probability of rejecting the null hypothesis when it is true. It determines the probability of making a Type I error (rejecting H0 when it is actually true). Common choices for α are 0.05 or 0.01.

Determine the test statistic: Select an appropriate test statistic that follows a Poisson distribution based on the data and hypotheses being tested. The test statistic should be able to capture the effect or difference being examined.

Calculate the critical region: The critical region is the set of values of the test statistic for which the null hypothesis will be rejected. To determine the critical region, we need to find the values of the test statistic that correspond to the rejection region based on the significance level α.

Use the Poisson distribution: Since the sum of independent Poisson random variables follows a Poisson distribution, we can utilize the Poisson distribution to determine the probabilities associated with different values of the test statistic. We can calculate the probabilities for the test statistic under the null hypothesis.

Compare the probabilities: Compare the probabilities calculated under the null hypothesis with the significance level α. If the calculated probability is less than or equal to α, it falls in the rejection region, and we reject the null hypothesis. Otherwise, if the probability is greater than α, it falls in the acceptance region, and we fail to reject the null hypothesis.

It is important to note that the specific details of determining the rejection region and performing hypothesis testing depend on the specific test being conducted, the data at hand, and the nature of the hypotheses being tested. Different tests and scenarios may require different approaches and considerations.

The correct answer is b. we know the standard deviation of the population.

The Nearly Normal condition, also known as the Central Limit Theorem, states that the sampling distribution of the sample mean tends to be approximately normal, even if the population distribution is not normal, under certain conditions. One way to meet the Nearly Normal condition is by knowing the standard deviation of the population.

When the standard deviation of the population is known, the sample size does not have to be large for the sampling distribution of the sample mean to be approximately normal. This is because the standard deviation provides information about the variability of the population, allowing for a more accurate estimation of the sample mean distribution.

While the other options (a, c, and d) may be relevant in specific scenarios, they are not directly related to meeting the Nearly Normal condition as defined by the Central Limit Theorem.

1/12 OR 0.0083% PROBABILITY is that  sit down in correct age order either clockwise.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.

An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

The likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin.

The coin is fair, thus the outcomes "heads" and "tails" are equally likely; the likelihood of "heads" is equal to the likelihood of "tails"; and because there are no other conceivable outcomes, the likelihood of either "heads" or "tails" is 1/2 (which is also an acceptable spelling).

The surfaces described by the given vector equations are:

1.The surface is a hyperbolic paraboloid.

2.The surface is a part of a cylinder with radius 3 and axis parallel to the y-axis.

3.The surface is a plane parallel to the xy-plane and shifted upwards by 1 unit.

4.The surface is a twisted cylinder along the y-axis.

A vector equation of a surface in three-dimensional space is a function that maps a pair of parameters, say u and v, to a three-dimensional point in space (x, y, z) represented as a vector. The vector equation can be written in the form of r(u, v) = <x(u, v), y(u, v), z(u, v)>.

In general, there are different ways to represent the same surface using vector equations. For example, the surface of a sphere of radius r centered at the origin can be represented by the vector equation r(u, v) = <r sin(u) cos(v), r sin(u) sin(v), r cos(u)>, where u is the polar angle (measured from the positive z-axis) and v is the azimuthal angle (measured from the positive x-axis).

Vector equations can be useful in studying the geometry and properties of surfaces, such as determining their tangent planes, normal vectors, curvature, and surface area. They can also be used to parametrize surfaces for numerical calculations and simulations.

12:00 am midnight

Step-by-step explanation:

Given;

I can read a 336-page book in 6 hours.

My rate r1 = 336/6 pages per hour = 56 pages per hour

Jayne can read a 144-page book in 3 hours.

Jayne rate r2 = 144/3 = 48 pages per hour

If I start reading a 5000-page book at noon and Jayne starts reading the same book at 10 AM

Taking 10 am as the reference time.

Let x represent the time from 10 am at which they would both be on the same page.

For me;

Since i started by noon; 2 hours after 10 am

Time t1 = x-2

For Jayne;

She started by 10 am

Time t2 = x

For them to be on the same page they must have read the same number of pages;

Number of pages read = rate × time

r1(t1) = r2(t2)

Substituting the values;

56(x-2) = 48(x)

56x - 112 = 48x

x(56-48) = 112

x = 112/(56-48)

x = 14 hours

Since 10 am is the reference, the time would be;

=10 am + x = 10 am + 14 hours

= 24:00

= 12:00 am midnight

a) the population cannot be negative, the limiting population is 4300.

b)the population is increasing when 0 < p < 4300 and decreases when p > 4300.

c)the equilibrium solutions are p = 0 and p = 4300.

(a) To determine when the population is increasing or decreasing, we need to look at the sign of dp/dt.

\(\frac{dp}{dt} = 1.2p(1 - \frac{p}{4300})\)

For dp/dt to be positive (i.e. population is increasing),

we need\(1 - \frac{p}{4300} > 0, or \ p < 4300.\)

For dp/dt to be negative (i.e. population is decreasing),

we need\(1 - \frac{p}{4300} < 0, or p > 4300.\)

Therefore, the population is increasing when 0 < p < 4300 and decreases when p > 4300.

(b) To find the limiting population, we need to find the value of p as t approaches infinity.

As t approaches infinity,\(\frac{dp}{dt}\)approaches 0. Therefore, we can set \(\frac{dp}{dt}\) = 0 and solve for p.

0 = 1.2p(1 - p/4300)

Simplifying, we get:

0 = p(1 - p/4300)

So, either p = 0 or 1 - p/4300 = 0.

Solving for p, we get:

p = 0 or p = 4300.

Since the population cannot be negative, the limiting population is 4300.

(c) Equilibrium solutions occur when\(dp/dt = 0.\)We already found the equilibrium solutions in part (b): p = 0 and p = 4300.

Therefore, the equilibrium solutions are p = 0 and p = 4300.

increasing or decreasing, and at p = 4300,  the population is decreasing

but not changing in size.

(a) To determine when the population is increasing or decreasing, we

need to find the sign of dp/dt. We have:

dp/dt = 1.2p(1 - p/4300)

This expression is positive when 1 - p/4300 > 0, i.e., when p < 4300, and

negative when 1 - p/4300 < 0, i.e., when p > 4300.

Therefore, the population is increasing when 0 < p < 4300, and

decreasing when p > 4300.

(b) To find the limiting population, we need to solve for p as t approaches infinity. To do this, we set dp/dt = 0 and solve for p:

1.2p(1 - p/4300) = 0

This equation has two solutions: p = 0 and p = 4300. Since the population cannot be negative, the limiting population is 4300.

(c) To find the equilibrium solutions, we need to solve for p when dp/dt = 0. We already found that the only solutions to dp/dt = 0 are p = 0 and
