The length of each leg of a right triangle given that one angle is 22° and the length of the hypotenuse is 10 inches are 3.75 and 9.27 inches respectively.

In order to determine the length of the opposite side and adjacent side, we would apply both the cosine and sine trigonometry ratio because the given side lengths represent the hypotenuse of a right-angled triangle.

cos(θ) = Adj/Hyp

Where:

By substituting the parameters into the sine trigonometry ratio formula, we have the following;

sin(θ) = Opp/Hyp

sin(22) = y/10

y = 10sin(22)

y = 3.75 inches.

For the adjacent side, we have:

cos(θ) = Adj/Hyp

cos(22) = x/10

x = 10cos(22)

x = 9.27 inches.

Using the z-distribution, we have that:

\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)

Item a:

We are interested in the confidence interval for the true proportion of kids who want to be a doctor, hence the parameter of interest is the proportion of kids who want to be a doctor.

Item b:

Fifty-five of the 1000 kids want to be a doctor, hence, since there are more than 10 successes and more than 10 failures in the sample, the conditions are met.

Item c:

The lower limit of this interval is:

\(\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.05 - 2.327\sqrt{\frac{0.05(0.95)}{1000}} = 0.0339\)

The upper limit of this interval is:

\(\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.05 + 2.327\sqrt{\frac{0.05(0.95)}{1000}} = 0.066\)

The interval is (0.0339, 0.066).

Item d:

We are 98% sure that the true proportion of kids who want to be a doctor is between 0.0339 and 0.066.

The variety of nonrandom sampling that takes proportions into consideration is: c) quota

Quota sampling is the variety of nonrandom sampling that takes proportions into consideration. In quota sampling, the researcher selects a specific number of participants from each subgroup of the population based on their proportion in the overall population. This ensures that the sample represents the different subgroups in the population proportionately.

In quota sampling, the researcher selects participants based on specific characteristics or proportions to ensure that the sample represents the target population accurately. The researcher sets quotas for different groups or segments based on known proportions or desired representation in the population.

For example, if a population consists of 60% males and 40% females, a quota sample might be designed to include the same proportions of males and females. The researcher would continue to select participants from each group until the quotas are met.

On solving the provided question, by properties of parallel lines we got to know that -  1 - A  2 - C  3 - B  4 - D

When two or more lines cross the intersection line, alternate exterior angles result. These angles are created on a number of sides outside the transverse lines. Any two parallel lines that cross one another create two angles with the horizontal line. In the area between the parallel lines, interior angles are formed, while alternate exterior angles are formed in the area outside the parallel lines.

Step-by-step explanation:

The set, together with the indicated operations, satisfies all the vector space axioms, so it is a vector space.

To determine if the set M2,4 with the standard operations (addition and scalar multiplication) forms a vector space, we must check if it satisfies the following vector space axioms:

1. Closure under addition
2. Commutativity of addition
3. Associativity of addition
4. Existence of additive identity (zero vector)
5. Existence of additive inverse
6. Closure under scalar multiplication
7. Distributive property for scalar and vector addition
8. Associativity of scalar multiplication
9. Identity property of scalar multiplication

M2,4 represents the set of all 2x4 matrices, i.e., matrices with 2 rows and 4 columns. Let's verify if the axioms hold for this set:

1. Closure under addition: Adding two 2x4 matrices results in another 2x4 matrix.
2. Commutativity of addition: For any two 2x4 matrices A and B, A + B = B + A.
3. Associativity of addition: For any three 2x4 matrices A, B, and C, (A + B) + C = A + (B + C).
4. Existence of additive identity: The zero matrix (a 2x4 matrix with all elements being 0) is the additive identity.
5. Existence of additive inverse: For any 2x4 matrix A, there exists a matrix -A such that A + (-A) = 0 (the zero matrix).
6. Closure under scalar multiplication: Multiplying a 2x4 matrix by a scalar results in another 2x4 matrix.
7. Distributive property for scalar and vector addition: For any scalar c and 2x4 matrices A and B, c(A + B) = cA + cB.
8. Associativity of scalar multiplication: For any scalars c and d and a 2x4 matrix A, (cd)A = c(dA).
9. Identity property of scalar multiplication: For any 2x4 matrix A, 1A = A.

Since M2,4 with the standard operations satisfies all the vector space axioms, it is indeed a vector space.

By definition of quotient, the rational number 1/3 represents a periodic infinite decimal number. That is to say, 1/3 is equivalent to the decimal number \(0.\overline{333}\)

The quotient of a fraction is found by dividing the fraction. Results in decimal form can be finite and infinite, infinite forms can be periodic or no periodic. This fraction represents a periodic infinite decimal number.

Answer:

The length is 6, and the width is 4.

Step-by-step explanation:

The length and width add up to 10. 6 + 4 = 10.

A quarter of the width plus the length = 7. A quarter of 4 = 1. 1 + 6 = 7

Answer:

Width is 4 inches, Length is 6 inches

Step-by-step explanation:

Let us set a variables, l for length, and w for width. Now, we can write two expressions with the given information:

1. The length, l, and one quarter of the width, w, add up to 7in. Therefore,:

l+0.25w=7

2. The length, l, and the width, w, add up to 10in. Therefore,:

l+w=10

Let us now subtract the first equation from the second to find the variable, w. When we do this, we should make sure that we are subtracting on both sides:

\(l+w-(l+0.25w)=10-7\\l+w-l-0.25w=3\\0.75w=3\\w= 4\)

Now, let us substitute this 4 into w of the equation to obtain l:

l+w=10

l+4=10

l=6

Therefore, the width of the rectangle is 4 inches and the length of the rectangle is 6 inches.

Answer:

x = 98 degrees

Step-by-step explanation:

A heptagon has a total of 900 degrees for the interior angles. Add up all the angles and then subtract from 900 to find x.

146+122+142+140+110+142 = 802.

900-802 = 98

Answer:

x = 98

Step-by-step explanation:

This shape has 7 sides. Using the formula n - 2 we can get the number of triangles. n represents the number of sides.

n - 2 = 5

All triangles have 180 degrees, so multiply 180 by the number of triangles (5).

180 × 5 = 900

The total number of degrees in this shape is 900. Adding the other angle measures and then subtracting them from 900 gives us x.

146 + 122 + 142 + 140 + 110 + 142 = 802

900 - 802 = 98.

x = 98

Answer:

x = 47 degrees

Step-by-step explanation:

ok so the 2 lines m and n are parallel while going through line t

The y-intercept is 2 and the x-intercept is 30.

A man who has hemophilia and a woman who is a carrier has:

A hemophilia carrier is what?

Both an X chromosome from the mother and an X chromosome from the father are passed down to a daughter. Let's say the gene for typical blood coagulation is present on her mother's X chromosome. Let's say her father's X chromosome carries the hemophilia gene.

Since the normal blood clotting gene from the mother is dominant, the daughter won't get hemophilia. The hemophilia gene's instructions cannot be transmitted because of this.
