The local ranger station tracked and tagged 2,844 adult female black bears in a national park. A random sample of 9 adult female black bears from those tagged had an average body weight of 203 pounds with standard deviation 25 pounds. Which of the following is a point estimate for the population mean weight of all female black bears that are tagged?

a. 9
b. 25/√9
c. 25
d. 203
e. 2,844

Answers

Answer:

203

Step-by-step explanation:

Sample size, n = 9

Mean weight, m = 203

Standard deviation = 25

Point estimate for the population mean weight of all black bears that are tagged `

The point estimate of the population mean ;

ΣX / n

Sum of sample / sample size ;

This is the mean value formula for the sample.

However, since it has been given in the question that, sample mean weight value = 203 ; then the point estimate of the population mean weight = 203

Option d: 203 is a point estimate for the population mean weight of all female black bears that are tagged.

Given that:Total tagged adult female black bears in the national park = 2,844Sample size = 9Sample mean of body weight of female black bears = 203 pounds.To find:

Point estimate of population mean weight of female black bears that are tagged.

Calculations and explanations:

Point estimation of population mean is calculated by calculating the mean of the sample drawn from that population. This estimate is considered best guess of population mean.

The sample mean is obtained by:

[tex]\overline{x} = \dfrac{\sum \text{sample observations}}{\text{sample size}}[/tex]

Since it is given that the sample mean is 203, thus we have the point estimate of the population mean as 203 too.

Thus, 203 is a point estimate for the population mean weight of all female black bears that are tagged.

An article describes a study in which a new type of ointment was applied to forearms of volunteers to study the rates of absorption into the skin. Eight locations on the forearm were designated for ointment application. The new ointment was applied to four locations, and a control was applied to the other four. How many different choices were there for the four locations to apply the new ointment

Answers

Answer:

There were 70 choices for the four locations to apply the new ointment

Step-by-step explanation:

The order in which the locations are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

How many different choices were there for the four locations to apply the new ointment

Four locations from a set of 8. So

[tex]C_{8,4} = \frac{8!}{4!(8-4)!} = 70[/tex]

There were 70 choices for the four locations to apply the new ointment

A line segment has an endpoint at (-7, 11) and (-6, 4), what is the length of
the segment?

Answers

Answer:

d = 5√2 units

Step-by-step explanation:

Let's use the distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]

Plug in the values with your endpoints.

d = √[(-6 - (-7))² + (4 - 11)²]

Solve within the parentheses.

d = √[(1)² + (-7)²]

Solve the exponents.

d = √[1 + 49]

Solve within the brackets.

d = √50

Simplify the square root.

25 • 2 = 50

√25 • √2 = √50

5 • √2 = √50

d = 5√2 units

Three years ago A's age was double of B's
age. Seven years hence, the sum of their
ages will be 83 years. Find the present
age of A?​

Answers

Answer:

present Age of " A " will be (x) = 45 years

present Age of " B " will be (y) = 24 years

Step-by-step explanation:

Age of " A " = x years

Age of " B " = y years

(Three years ago A's age was double of B's age.)

==> (x-3) = 2 * (y-3)

==> x - 2y = -6 + 3

==> x - 2y = -3 -------------(1)

(Seven years hence, the sum of their ages will be 83 years )

==> (x+7)+(y+7) = 83

==> x + y = 83 - 14

==> x + y = 69 ------------(2)

Subtract equ.(1) & equ(2)

==> -2y - y = -3 - 69

==> -3y = -72

==> y = -72/(-3)

==> y = 24

Keep value of y in equ(2)

==> x + 24 = 69

==> x = 69 - 24

==> x = 45

A box will be built with square base and an open top. Material for the base costs $8 square foot, while material for the side's costs $2 per square foot. Find the dimension of the box of maximum volume that can be built for $2400.​

Answers

All you have to do is add it could be so simple 8$ + $2 + $2400

The height and side of the box for the maximum volume are 20 feet and 10 feet respectively.

What is area?

Area is the amount of space occupied by a two-dimensional figure.

How to calculate the area of square?

The area of square is the product of the length of each side with itself.

[tex]A = a^{2}[/tex]

Where,

A is the area of square

a is the length of the side of square

What is volume?

Volume is the measure of the capacity that an object holds.

Formula for the volume of cuboid

volume = length × breadth × height

According to the given question

We have

A box with the open top and square base.

Let x be the side of the box. And h be the height of the box

Also, the cost of material for the base is $8 and for side is $2 per square foot.

The total cost of material for the box is $2400

⇒[tex]8x^{2} + 4(2xh) = 2400[/tex]

⇒ [tex]8x^{2} + 8xh = 2400\\[/tex]

⇒[tex]x^{2} + xh = 300[/tex]

⇒ [tex]h = \frac{300-x^{2} }{x}[/tex]

Therefore,

volume of the box

[tex]= x^{2} h[/tex]

= [tex]x^{2} \frac{3000-x^{2} }{x}[/tex]

= [tex]x(300-x^{2} )[/tex]

= [tex]300x - x^{3}[/tex]

for the maximum volume,[tex]\frac{d}{dx}(v)=0[/tex]

⇒ [tex]300 - 3x^{2} =0[/tex]

⇒[tex]300 = 3x^{2}[/tex]

⇒ [tex]x^{2} =100[/tex]

⇒ x = ± 10

⇒ x= 10 feet  (x = -10 not possible)

So, h = [tex]\frac{300-100}{10} = 20feet[/tex]

Hence, the height and side of the box for the maximum volume are 20 feet and 10 feet respectively.

Answers

Answer:

See answers below

Step-by-step explanation:

T59 = a+58d = -61

T4 = a+3d = 64.

Subtract

58d-3d = -61-64

-55d = -125

d =125/55

d = 25/11

Get a;

From 2

a+3d = 64

a+3(25/11) = 64

a = 64-75/11

a = 704-75/11

a = 629/11

T23 = a+22d

T23 = 629/11+22(25/11)
