The type of triangle is △STR is isosceles triangle.

A triangle is a flat shape bounded by three sides. In another sense, a triangle is formed by three line segments called sides and each side intersects with two other sides.

When classified from its angles, triangles consist of acute triangles, right triangles, and obtuse triangles. Even so, the sum of the angles of a triangle is always 180 degrees. Based on the classification of its sides, triangles consist of equilateral triangles, arbitrary triangles, and acute triangles.

The test score is 91.5.

z-score:

A z-score is the number of standard deviations from the mean value of the reference population.

Here we have to find the test score.

Mean(μ) = 90

Standard deviation(б) = 15

z-score = 0.1

Formula for z-score:

z = X - μ / б

Now putting the values in the equation:

0.1 = X - 90 / 15

1.5 = X - 90

X = 91.5

Therefore the test score is 91.5.

The vertex of the function is at (–3,–16). The graph is increasing on the interval x > –3. The graph is positive only on the intervals where x < –7 and where x > 1. The graph is negative on the interval x < –4.

Solution:

1) The vertex of the function is at (–4,–15).

Ans.This is false.

2) The vertex of the function is at (–3,–16).

Ans. This is true. from the graph it is clearly shown A is vertex of graph.Which is (-3,-16)

3)The graph is increasing on the interval x > –3.

Ans. This region is located in graph with red colour,here it is easily shown that in this region graph continuously increasing.

This is true.

4)The graph is positive only on the intervals where x < –7 and where x > 1.

Ans: Yes,it is true.

Because when x<-7 graph is decreasing but have positive values and when x>1,graph is increasing and have positive values.

5)The graph is negative on the interval x < –4.

Ans:Yes,yellow part is shown the region of x<-4

here value of graph continuously decreasing.

Answer: A. To find the number of inches the Komodo dragon still needs to grow to be 120 inches long, we can subtract its current length from 120:

Length still needed to grow = 120 inches - 92 inches

B. Solving the equation:

Length still needed to grow = 120 - 92

= 28 inches

Therefore, the Komodo dragon still needs to grow 28 inches to reach a length of 120 inches.

The number which can be raised by 3 to give the value of 11 is 2.224.

The idea of exponentiation, or repeated multiplication, is where the exponential function got its start, but more recent definitions—there are several that are equivalent—allow it to be rigorously extended to all real arguments, including irrational values.

Given:

The exponent to which 3 must be raised to obtain 11,

Assume the number is x then, According to the statement,

x³ = 11

x  = ∛11

x = 2.224

80  unit²  is the area of the polygon in square units .

What do you mean by polygon?

A polygon is a closed object in a two-dimensional plane comprised of line segments rather than curves. The word "polygon" is a combination of the words "poly" (which meaning many) and "gon" (means sides). In order to create a closed figure, at least three line segments must be connected end to end.

The area of the polygon is required.

The area of the polygon is D. 80 square units

For triangle BCD

Simple random sampling is a sampling method that can be generalized to at least the population from which the sample was drawn.

Using simple random sampling, each component of the population has an equal probability and likelihood of being chosen. This sampling strategy is also frequently referred to as a method of chance since the selection of items in this case completely rests on chance or luck.

Simple random sampling is a simple sampling technique that is readily integrated into more sophisticated sampling techniques. Every sample has the same chance of being picked, which is the key characteristic of this sampling technique.

Answer:

7√(x) = 14

Step-by-step explanation:

An estimator is unbiased ​ if the expected value of the estimator is exactly equal to the parameter that it is estimating. So, the answer is unbiased.

An estimator is said to be unbiased if, on average, it provides an estimate of a population parameter that is exactly equal to the true value of the parameter. if we were to take many samples from the same population and compute the estimator for each sample, the average of these estimators would converge to the true population parameter.

Unbiased estimators are considered to be desirable, as they provide an estimate that is not systematically too high or too low, and thus can be used to make accurate inferences about the population. However, some estimators may be biased, meaning that they tend to overestimate or underestimate the population parameter on average, and thus may not provide accurate estimates.

A Random Variable is a defined as a variable whose value depends on the outcome of a random event.

Option (c) : the random event is the selection of 50 students from the school to measure their height. The mean height of this sample of 50 students is a random variable because it can vary depending on the specific students who are selected.

Option (a) : The true mean height of all students from your school is a population parameter and is a fixed value, so it cannot be called as a random variable.

Option (b) : The mean of the sampling distribution of mean heights for samples of size 50 is a population parameter as well, and it represents the average of all possible sample means of size 50 taken from the population. So,  it is a fixed value and not a random variable.

Answer:

$36.33

Step-by-step explanation:

So, when finding the percentage of a number you move the decimal point to the left two times.

39.93 x .15 = 6

39.93 - 6 = 33.93

(I subtracted the 6 because it was what was taken off by the coupon)

33.93 x .07 = 2.4

33.93 + 2.4 = 36.33

(Again, I added the 2.4 because it was what was added on by the sales tax)

Rounding to the nearest tenth of a cent, the unit cost of A&W Root Beer per can is approximately $0.67.

To find the unit cost of A&W Root Beer per can, we need to divide the total cost by the number of cans.

Given:

Total cost = $3.99

Number of cans = 6

To find the unit cost per can, we divide the total cost by the number of cans:

Unit cost = Total cost / Number of cans

Unit cost = $3.99 / 6

To calculate the unit cost, we divide $3.99 by 6:

Unit cost = $0.665

Please note that the rounding was done to the nearest tenth of a cent, so $0.665 is rounded up to $0.67.

3.9 × 105 in standard form

Next, we multiply 3.9 and 105

So, we have the following representation

3.9 × 105 = 409.5

The above expression cannot be solved further

And it is already in its standard form

Other way to represent the number is in scientific form

And this is represented as

The probability that at least one die is showing 2 and the sum of the two dice is 6 is 1/18

A probability is a number that reflects the chance or likelihood that a particular event will occur. The certainty of an event to occur is 1 and it equivalent to 100% in percentage.

Probability = sample space /total outcome

The possible total out come for rolling two dice is 36.

For two dice two have a sum of 6 and at least one must show 2, the result must either be 2,4 or 4,2. Therefore the sample space is 2
