Answer:

Treaty of Guadalupe Hidalgo (1848) This treaty, signed on February 2, 1848, ended the war between the United States and Mexico. By its terms, Mexico ceded 55 percent of its territory, including parts of present-day Arizona, California, New Mexico, Texas, Colorado, Nevada, and Utah, to the United States.

Step-by-step explanation:

Answer:

Mexico was forced to recognize the Rio Grande as Texas's southern border and to recognize Texas's annexation to the United States. Mexico also had to give up the territories of New Mexico and California. In return, the United States paid $15,000,000 for these territories and agreed to assume Mexican war debts to United States citizens in Texas totaling $3,500,000. The Treaty was ratified by the United States Senate after a bitter debate.

Step-by-step explanation:

(f o h)(x) = -2(-x - 3) - 1

(f o h)(x) = 2x + 6 - 1

(f o h)(x) = 2x + 5

Answer:

c. Cluster sampling

Step-by-step explanation:

Taking into account that the exercise researcher is looking with limited resources to study a population that is divided, her best option is cluster sampling, which is a method applicable to this type of population, we could select in each group randomly her sample, the observational study is discarded because she does not have much availability of time or resources, nor would the stratified study be useful because she should select subgroups and create them to take samples and this would take more time and resources and sampling systematic is not adequate because it must have all the individuals and after having the list select the sample, but as we know, it is a process that will study the number of individuals so this option is not feasible.

Answer:

Cluster sampling

Step-by-step explanation:

Cluster sampling is almost always more economical or more practical than stratified sampling or simple random sampling as it reduces costs by increasing sampling efficiency. Due to the fact that she has limited resources, this method is better to observe clusters of units in a population than randomly selected distributed in the local nature preserve and this method is more economical and quick.

Step-by-step explanation:

The correct answer is 1365 ft

Explanation:

The volume refers to the space a body occupies, in the case of the bin made by Lauren this is composed of two rectangular prisms (one in the front and one in the back). Additionally, the volume of each prism can be calculated by multiplying the height, length, and width this means Volume= H x L x W.

According to this, the volume of the front rectangular prism is 735 considering 7ft (H) x 21ft (L) x 5ft (W) = 735 and the volume of the rectangular prism in the back is 630 considering the height of this is 3ft more than the one in the front this means the heigh is 10ft and 10ft (H) x 21ft (L) x 3ft (W) = 630. Finally, it is necessary to add the two volumes to find the total volume, thus 630+ 735 is equivalent to 1365 ft, which is the volume of all the bin.

a) response variable

Step-by-step explanation:

The response variable is the variable that depends on other variables such as the independent or explanatory variable, it is the variable that is being tested. The response variable is also called the dependent variable.

In linear regression, the y variable is referred to as the response variable while the x variable is referred to as the explanatory or independent variable.

In this case the y variable is "the number of times they cough in a day" and this variation depends on the x variable "number of cigarettes a person smokes in a day".

Answer:

74.4

Step-by-step explanation:

It is already rounded to the nearest tenth of a percent. If it was rounded to the nearest percent it'd be 74%.

Answer:

74.4% rounded to the nearest tenth of a percent is 74.4%

Step-by-step explanation:

This is how to round 74.4 to the nearest tenth.

Firstly, 74.4 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:

Integer Part: 74

Fractional Part: 4

To round 74.4 to nearest tenth means to round the numbers so you only have one digit in the fractional part.

74.4 already has only one digit in the fractional part. Thus, 74.4 is already rounded as much as possible to the nearest tenth and the answer is:

A. [tex]f(x) = -3(x +2)^2-2[/tex]

Step-by-step explanation:

There is a -3 being multiplied, making the function on the graph narrower from the original. The -3 also makes the function flip over the x-axis, since it's negative. There is also a 2 being added in (x + 2), meaning that it shifts left by 2 units. There is a -2, meaning that the function shifts 2 units down the graph.

Based on the information that applies to this function, this is the only function that represents f(x) on the graph given.

Answer:

3.67% probability of randomly seleting 37 cigarettes with a mean of 0.809 g or less.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this question, we have that:

[tex]\mu = 0.895, \sigma = 0.292, n = 37, s = \frac{0.292}{\sqrt{37}} = 0.048[/tex]

Find the probability of randomly seleting 37 cigarettes with a mean of 0.809 g or less.

This is the pvalue of Z when X = 0.809.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.809 - 0.895}{0.048}[/tex]

[tex]Z = -1.79[/tex]

[tex]Z = -1.79[/tex] has a pvalue of 0.0367

3.67% probability of randomly seleting 37 cigarettes with a mean of 0.809 g or less.

Answer:

6 inches

Step-by-step explanation:

Answer:

Radius of the circle is of 3 inches.

Step-by-step explanation:

It is given that the area of the circle is 113.04,

Let the radius of the circle be of "a" units

=======================

From the properties of circle, we know : -

Area of circle = πr^2 , where r is the radius of the circle.

======================

Then, comparing the question with the identity :

= > πr^2 = 113.04 sq. inches

= > 3.14 x r^2 =  113.04 sq. inches

= > r^2 = 113.04 / 3.14 sq.inches

= > r^2 = 36 sq. inches

= > r = 6 inches

Hence,

r or radius of the circle is of 6 inches.

Game:  1/2 lb; Textbook:  2 lb

Step-by-step explanation:

Let the weights of game and textbook be g and t respectively.

Then 6g + 9t = 21 (pounds), and

8g + 9t = 22 (pounds)

Eliminate the variable t by subtracting the first equation from the second.  We get:

2g = 1 (pounds)

Thus, 1 game weights 1/2 lb.

Since 6g + 9t = 21, and g = 1/2 lb,

3 + 9t = 21, or 9t = 18

Then t = 18/9.  1 textbook weighs 2 lb

Answer: The answer is dividing the radius in half

Step-by-step explanation: it is a half circle, remember that radius is half the diameter

The radius will be half the refracted base.

Radius is one of the important parts of a circle. It is the distance between the center of the circle to any point on its boundary. In other words, when we connect the center of a circle to any point on its circumference using a straight line, that line segment is the radius of that circle. A circle can have more than one radius because there are infinite points on its circumference. This means that a circle has an infinite number of radii and all the radii of the circle are equidistant from the center of the circle. The size of the circle changes when the length of the radius varies.

The radius of a circle can be found using the three basic radius formulas i.e., when the diameter, the area, or the circumference is known. Let us use these formulas to find the radius of a circle.

As, it is given that the  base of the refraction cup is a half circle.

So, to find the radius of the circle we have to we have to half the base.

This is because the radius is half of the diameter.
