Answer:

B = 142

Step-by-step explanation:

First, you need to find the angle of the third angle of the triangle. The three angles of a triangle always add up to 180, so it will be:

n + 77 + 65 = 180

= n + 142 = 180

= n = 38

Now, you need to find the angle supplementary to 38, as 38 and B are linear angles. Two supplementary angles add up to 180, so:

B + 38 = 180

= B = 142

The measure of the angle marked as B that is ABD in the given figure is equal to 142°.

Let us consider the vertices of the triangle are A, B , C

Where

measure of angle A = 77 degree

measure of angle C = 65 degree

Ray CB extends to Point D such that C-B - D.

Sum of all the interior angles in a triangle is equal to 180 degree.

Let measure of angle ABC be x degree.

m∠ABC + m∠BAC + m∠BCA  = 180°

⇒ x° + 77° + 65° = 180°

⇒ x° + 142°= 180°

⇒ x° = 38°

Now angle ABC and angle ABD are linear pair.

m∠ABC + m∠ABD = 180°

⇒ 38° + m∠ABD = 180°

⇒ m∠ABD = 180° - 38°

⇒ m∠ABD = 142°

Therefore, measure of the angle marked as B is equal to  142°.

The product of -1 and -3/4 is 3/4, and the quotient of -3/4 divided by 1/-3 is 9/4.

A quotient is defined as the outcome of dividing an integer by any divisor that can be said to be a quotient. The dividend contains the divisor a specific number of times.

Here are some multiplication and division sentences that make the product and quotient of -3/4:

Multiplication:

-1 × (-3/4) = 3/4

In this multiplication sentence, we're multiplying -1 by -3/4. The product of these two values is 3/4. We can also think of this as "negative times negative is positive" - when we multiply two negative numbers, we get a positive result.

Division:

(-3/4) ÷ (1/-3) = 9/4

In this division sentence, we're dividing -3/4 by 1/-3. To divide by a fraction, we can multiply by its reciprocal. So we can rewrite this as (-3/4) × (-3/1), which simplifies it to 9/4.

So, the product of -1 and -3/4 is 3/4, and the quotient of -3/4 divided by 1/-3 is 9/4.

The difference between the two confidence intervals is given as follows :

Width of confidence interval is directly proportional to confidence level.

This is because,  width is directly proportional to critical value (z or t), which is directly proportional to confidence level.

Now, width is inversely proportional to square root of sample size.

But if sample size is same for both levels of confidence. Then, sample size would have same effect.

Hence, the appropriate answer here is,

Answer:

D- Yes. (3b+3)−(b+a+3)

Step-by-step explanation:

hope this helps<3

Here we have a problem of the subtraction of polynomials, is important to know that the subtraction is really straightforward.

The correct option is: Yes. (3b+3)−(b+a+3)

We will see that yes, two polynomials can be subtracted such that the difference is a binomial (a binomial is a polynomial of 2 terms).

Suppose the polynomials:

\(p(x) = a*x^2 + b*x + c\\q(x) = b*x\)

If we take the difference of these two:

\((a*x^2 + b*x + c) - (b*x) = a*x^2 + c\)

So at the end, we have a binomial.

By looking at the options we can see one really similar to ours, it is:

Yes:

\((3b + 3) - (b + a + 3)\\(3b + 3) - b - a - 3\\3b + 3 - b - a - 3 \\3b - b - a\\2b - a\)

Which is the last option, and we can see that after the subtraction of polynomials we have a binomial.

Complementary angles has sum of \(90^{o}\) and supplementary angles have sum of \(180^{o}\) , The answer is \(62^{o}\) and \(48^{o}\) .

When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together.

When two angles' measurements add up to 90 degrees, they are said to be complementary. When two angles' measures sum up to 180 degrees, they are said to be supplementary. Keeping in mind that the letter s follows the letter c in the alphabet and that 180 is greater than 90 can help you avoid conflating these definitions.

\(28^{o}\)

complement = \(90^{o}-28^{o}\) = \(62^{o}\)

\(132^{o}\)

supplement= \(180^{o}-132^{o}\) = \(48^{o}\)

For k1Θ¹ + k2Θ² to be an unbiased estimator of θ, the condition that must be imposed on the constants k1 and k2 is that k1 + k2 = 1.

Let Θ¹ and Θ² be two unbiased estimators of the same parameter θ. Then, we have E(Θ¹) = θ and E(Θ²) = θ. Now, let k1Θ¹ + k2Θ² be a linear combination of these two estimators, where k1 and k2 are constants.

To show that this estimator is unbiased, we need to find its expected value and verify whether it equals θ.

So, E(k1Θ¹ + k2Θ²) = k1E(Θ¹) + k2E(Θ²)

= k1θ + k2θ

= (k1 + k2)θ

For this estimator to be unbiased, we need (k1 + k2)θ to equal θ. Therefore, we must have k1 + k2 = 1.

Therefore, to ensure that k1Θ¹ + k2Θ² is an unbiased estimator of θ, we need to impose the condition that k1 + k2 = 1.

The measurement of the angle in the given triangle is 32.12°

The law of sines is defined as the ratio of side length to the sine of the opposite angle. It holds for all the three sides of a triangle, respective of their sides and angles.

Given that in a Δ OPQ p = 44 cm, o = 75 cm and ∠ O = 65°.

We are asked to find the value of ∠ P,

Using the sine law,

p / Sin P = o / Sin O

44 / Sin P = 75 / Sin 65°

44 / Sin P = 82.75°

Sin P = 44 / 82.75°

Sin P = 0.5317

P = sin⁻¹(0.5317)

P = 32.12°

A cumulative relative frequency distribution shows option (A) the proportion of data items with values less than the upper limit of each class

A cumulative relative frequency distribution shows the proportion of data items with values less than or equal to the upper limit of each class. It provides a cumulative summary of the data distribution by adding up the frequencies or proportions of all preceding classes.

To construct a cumulative relative frequency distribution, you start with the lowest class and calculate the relative frequency (proportion) of data items in that class. Then, for each subsequent class, you add the relative frequency of that class to the cumulative relative frequency from the previous class. This cumulative value represents the proportion of data items with values less than or equal to the upper limit of the current class.

In essence, a cumulative relative frequency distribution allows you to track the accumulation of data values as you move through the classes, giving insights into the overall distribution and the proportion of data items falling below specific values.

Thoma is 11

Step-by-step explanation:

We can call Aldo 'a' and Thoma 't'.

"Aldo's age is three times Thoma's age" can be written algebraically as a = 3t

"The sum of their ages is 44" can be written as a + t = 44

Because we know that a = 3t, we can substitute this into the equation a + t = 44 to get 3t + t = 44. This can be simplified to 4t = 44. If we divide both sides by four we get t = 11. This means that Thoma is 11.

Step-by-step explanation:

We have 6 green socks, 18 purple socks, and 12 orange socks.

Adding more purple sock means 6 green socks, 18+x purple socks, and 12 orange socks.

We have a  probability of 60% of getting a purple sock.

P( purple) = number of purple socks / total

.60 = (18+x) / (6+18+x+12)

.60 = (18+x) / (36+x)

Multiply each side by 36+x

21.6 +.6x = 18+x

Subtract 18 from each side

3.6x +.6x = x

A relation between a collection of inputs and outputs is known as a function.

A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

Each function has a range, codomain, and domain.

The usual way to refer to a function is as f(x), where x is the input.

One function, many. function onto (Surjective Function) into perform.

The function of a polynomial.

So, by observation we can find out the function:

y = 128(0.5)ˣ

Assume the teams after 1st round:

y = 128(0.5)ˣ

y = 128(0.5)¹

y = 128*0.5
