The surface area of the prism is 462.55 in².

We have,

Slant height = 20.7 in

The perimeter of the base.

= 11 + 11 + 11 + 11

= 44 in

And,

The lateral surface area of the prism.

= Area of all sides except the base area

So,

= 3 x ( 1/2 x 11 x 20.7)

There are same three triangles.

So we add up all the 3 triangles.

= 341.55 in²

And,

Area of the base.

= 11²

= 121 in²

And,

The surface area of the prism.

= Lateral surface area + base area

= 341.55 + 121

= 462.55 in²

Thus,

The surface area of the prism is 462.55 in².

The biologist was checking the condition for inference that (d) the observations within each sample are close to independent.

This is concluded from the fact that the biologist was checking if the product of sample size and the proportion of deer with chronic wasting disease in each sample was greater than or equal to 10. This is a commonly used rule of thumb to ensure that each sample has enough data to provide meaningful information about the population, and it is based on the idea that the sample size should be large enough such that the expected number of success (deer with chronic wasting disease) is at least 10 and the expected number of failures (deer without chronic wasting disease) is at least 10.

This helps to ensure that the observations within each sample are close to independent, as the sample proportions are unlikely to be greatly influenced by any individual deer in the sample.

Correct Question :

A wildlife biologist is doing research on chronic wasting disease and its impact on the deer populations in northern colorado. to estimate the difference between the proportions of deer with chronic wasting disease in two different regions, a random sample of 200 deer was obtained from one region and a random sample of 197 deer was obtained from the other region. the biologist checked for the following:

(200)(0.06)≥10

(200)(0.94)≥10

(197)(0.086)≥10

(197)(0.914)≥10

Which of the following conditions for inference was the biologist checking?

a. The population of deer within each region is approximately normal.

b. It is reasonable to generalize from the samples to the populations.

c. The samples are independent of each other.

d. The observations within each sample are close to independent.

e. The sampling distribution of the difference in sample proportions is approximately normal.

Concentric circles are internally tangent circles which is the true statement.

Geometry is the description of figures in a space with a specific number of dimensions and types. Plane geometry is the most prevalent sort of geometry (dealing with objects like the point, lines, circles, triangles, and polygons)

Concentric circles are circles that have the same center but different radii.

When two concentric circles are drawn, it is possible for them to be internally tangent, meaning that they touch each other at exactly one point and the point of tangency is inside both circles.

In this case, one circle is entirely contained within the other circle.

Mr. Farley used 0.4 pounds (or 6.4 ounces) of hamburger per patty.

The accepted method for representing both integer and non-integer numbers is the decimal numeral system. It is the expansion of the Hindu-Arabic numeral system to non-integer values. Decimal notation is the term used to describe the method of representing numbers in the decimal system.

To find the amount of hamburger used per patty, we need to divide the total amount of hamburger used by the number of patties:

amount per patty = total amount / number of patties

In this case, Mr. Farley used 4 pounds of hamburger to make 10 patties:

amount per patty = 4 pounds / 10 patties

We can evaluate this expression with a calculator to obtain:

amount per patty = 0.4 pounds per patty

Therefore, Mr. Farley used 0.4 pounds (or 6.4 ounces) of hamburger per patty.

The difference between the polynomials 9x² + 8x and 2x² + 3x is 7x² + 5x.

A polynomial is formed mathematically by combining one or more algebraic terms (monomials). The roots of "polynomial" are poly- (many) and -nomial (terms). A polynomial can have exponents (powers), constants (numbers), and variables (letters), but not negative exponents or variable division.

Polynomials are typically expressed in standard form. Furthermore, because there are no similar terms among the exponents, they are arranged in descending order (largest to smallest).

To find the difference between

(9x² + 8x) - (2x² + 3x)

We do calculation

= 9x² + 8x - 2x² - 3x

= 9x² - 2x² + 8x - 3x

= 7x² + 5x

Thus, the difference between the polynomials is 7x² + 5x.

The arithmetic mean is 59.

What is arithmetic mean?

It is the sum of collection of numbers divided by the count of the numbers.

Conider AB is the nuber satisfying the condition. Hence,

\(10A+B=A+B+A\times B\\9A=A\times B\\\)

Since AB is a two digit number hence, \(A\neq 0\\\). Hence, divide both sides by \(A\).

\(9=B\)

Hence, B is 9 and A can take any value from 1 to 9.

Hence, numbers are 19, 29, 39, 49, 59, 69, 79, 89,99.

Now, calculate arithmetic mean as follows:

\(AM=\frac{Sum \ of \ numbes}{Count \ of \ numbers}\\=\frac{19+29+39+49+59+69+79+89+99}{9}\\=59\)

The conditional probability that the ball is in box j, given that the search of box i did not uncover it, is P(j)/1-alpha(i)*P(i)  if j ≠ i.

Given a ball is in any one of n boxes, and is in the ith box with probability P(i). If the ball is in box i, a search of the box will uncover it with probability alpha i.The conditional probability that the ball is in box j, given that the search of box i did not uncover it, is P(j)/1-alpha(i)*P(i) if j ≠ i.

Proof: The probability that the ball is in box j and not in box i is given as: P(j) * (1 - alpha(i)) * (1 - P(i)). It is worth noting that there are four possible scenarios:  1. Box j is selected and found not to contain the ball

2. Box j is selected and found to contain the ball.                                                                                                                      3. Box i is selected and found not to contain the ball                                                                                                                   4. Box i is selected and found to contain the ball.

The first two scenarios will not satisfy the given condition, which requires that the ball not be found in box i. The last scenario implies that the ball is in box i, which is inconsistent with our assumption that the ball is not in box i.

We can express the conditional probability as follows: P(j|not in i) = P(j and not in i)/P(not in i) = P(j) * (1 - alpha(i)) / (1 - P(i) * alpha(i))= P(j)/(1- P(i)*alpha(i)) * (1 - alpha(i))when j ≠ i, this yields: P(j|not in i) = P(j)/(1- P(i)*alpha(i)) when j = i, we have: P(i|not in i) = 0. Therefore, the conditional probability is given as: P(j|not in i) = P(j)/(1- P(i)*alpha(i)) if j ≠ i. Hence Proved.

The rate of increase in the area of the square is 70 cm²/s when the area of the square is 25 cm².

Each side of a square is increasing at a rate of 7 cm/s. The area of the square is 25 cm².

The area of the square is given by A = a²

Where A is the area of the square and a is the length of the side of the square.

Differentiate both sides of the equation with respect to time we get:

dA/dt = 2a.da/dt

Substitute a = √A in the above equation to get:

dA/dt = 2√A.da/dt

Substitute A = 25 and da/dt = 7 in the equation dA/dt = 2√A.da/dt to get:

dA/dt = 2 x √25 x 7

dA/dt = 2 x 5 x 7

dA/dt = 70 cm²/s

Therefore, the rate of increase in the area of the square is 70 cm²/s.
