Step-by-step explanation:

R=85/2pi

the diameter is 27.07 ft.

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.

Perimeter refers to the total outside length of an object,

here, we have,

circumference is = 85 feet

now,

diameter = 85/pi

              =27.07

hence, the diameter is 27.07 ft.

Answer:

Well 1 litter is already 1000 ml so already its greater

Step-by-step explanation:

6.25 litter is essentially

6250 ml

And 6250>625

Answer:

Yes

Step-by-step explanation:

First we need to know that

1 L = 1000 ml

Using that, we can see that 6.25 L = 6250 ml

(6.25 x 1000, multiply by 1000 to convert from L to ml)

Therefore, 6.25 L (or 6250 ml) is bigger than 625 ml.

Step-by-step explanation:

Part A:

The maximum point is (2.5, 2531.25). This represents that $2.5 should be decreased from the original price to achieve the most profit from t-shirt sales.

Part B:

The y-intercept is seen to be around (0, 2500). This tells us that the profit made from the original price is $2500.

Part C:

Yes. The point (25, 0) is a solution. It tells us that if we decreased the original price by $25, we would make no/zero profit.

Answer:

Step-by-step explanation:

A. The optimal decrease in price to gain the maximum profit in sale:

Meaning if you reduce the price by $2.5, you will gain the maximum profit of $2531.25

B. It represents the amount of profit without any change in the current price on the t-shirt.

By shifting and expanding the original equation [tex]y=-x^{2}\\[/tex]

[tex]y = -5(x-2.5)^{2} + 2531.25[/tex]

[tex]x = 0 => y = 2500[/tex]

C. The solution is as in part B

It represents by reducing the price of each t-shirt, there is an initial increase in profit but eventually it will drop.

Answer: 0.2273

Step-by-step explanation:

Probability density function for uniform distribution is given by :-

[tex]f(x)=\dfrac{1}{b-a}[/tex], where x is uniformly distributed in [a,b].

Let x denotes the waiting time for this bus.

Given : The waiting time for a bus has a uniform distribution between 2 and 13 minutes.

Probability distribution function of x for interval [2,13] will be :-

[tex]f(x)=\dfrac1{13-2}=\dfrac{1}{11}[/tex]

Required probability : P(x<4.5) = [tex]\int^{4.5}_{2}f(x)\ dx[/tex]

[tex]=\int^{4.5}_{2}\dfrac1{11}\ dx\\\\=\dfrac1{11}[x]^{4.5}_{2}\\\\ = \dfrac1{11}(4.5-2)\\\\=\dfrac1{11}(2.5)\approx0.2273[/tex]

Hence, the probability that the waiting time for this bus is less than 4.5 minutes on a given day = 0.2273

Answer:

[tex]area = length \: \times \: width \\ = \frac{11}{2} \times \frac{3}{4} \\ = \frac{(11 \times 3)}{(2 \times 4)} \\ = \frac{33}{8} \\ area = 4.125 \: {m}^{2} \\ or \\ area = 4 \frac{1}{8} \: {m}^{2} [/tex]

Hope this helps :)

Answer:

Yes

Step-by-step explanation:

The central limit theorem says that If a random variable X from a population has mean u and finite variance σ² , then the sampling distribution of the sample mean X~ approaches a normal distribution with mean u and variance σ²/n as the sample size n approaches infinity.

It is interesting to note that we have neither assumed that the distribution of X is continuous nor we have said anything about the shape of the distribution , whereas the limiting distribution of X is continuous and normal. Thus the distribution of the sample means  regardless of the shape of the population having a finite variance , is approximately normal with mean u and variance σ²/n .

Therefore

(standard deviation/ √sample size)²= variance / n

2/ √20

= 2/4.472

=0.44721

The sampling distribution of X` is therefore approximately normal with mean ux=u and σx =σ/n

Yes, we estimate the standard deviation of the sampling distribution of means by using σ divided by the square root of n and this can be determined by finding the mean and standard deviation for the distribution of the sample means.

Given :

The mean for the distribution of the sample means is given by:

[tex]\mu_x = \mu[/tex]

[tex]\mu_x = 6.7[/tex]

The standard deviation for the distribution of the sample means is given by:

[tex]\rm \sigma_x = \dfrac{\sigma}{\sqrt{n} }[/tex]

[tex]\sigma_x = \dfrac{2}{\sqrt{20} }[/tex]

[tex]\sigma_x = 0.44721[/tex]

Yes, we estimate the standard deviation of the sampling distribution of means by using σ divided by the square root of n.

Answer:

15 bags

Step-by-step explanation:

Given that :

Capacity of mixer = 681 kg

Pounds per bag of cement = 100 pounds

Number of bags mixer can hold =?

Converting the capacity of mixer to pounds :

1kg = 2.205 pounds

681 kg = (681 * 2.205) pounds = 1501.605 pounds

Number of 100 pound bag of cement :

Capacity in pounds / 100 pounds

1501.605 / 100

= 15.016

= 15 bags of 100 pound cement

I assume you want to know the numbers in slope intercept form so... yeah

Step-by-step explanation

Answer:

The equation of the line in point-slope form is:

[tex]y+5=\:\frac{4}{3}\left(x-0\right)[/tex]

The graph is also attached below.

Step-by-step explanation:

Given

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

As we are given the y-intercept = -5

Thus, the point (0, -5) represents the y-intercept.

Point slope form:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

In our case,

substituting m = 4/3 and the point (0, -5) in the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y\:-\:\left(-5\right)\:=\:\frac{4}{3}\:\left(x\:-\:0\right)[/tex]

[tex]y+5=\:\frac{4}{3}\left(x-0\right)[/tex]

Therefore, the equation of the line in point-slope form is:

[tex]y+5=\:\frac{4}{3}\left(x-0\right)[/tex]

Step-by-step explanation:

Given these numbers in the question, multiply all three numbers to get your final answer which is 650,000.

The greatest value of n(AUB) is "145".

Given:

→ n(U) = 125

→ n(A) = 80

→ n(B) = 65

As we know,

The formula is:

⇒ [tex]n(A \cup B)_{max} = n(A)+n(B)[/tex]

By substituting the given values of n(A) and n(B), we get

                         [tex]=80+65[/tex]

                         [tex]=145[/tex]

Step-by-step explanation:

24 - 6 = 18

18 ÷ 1/3  =  18 × 3 = 54

Answer: 54

Step-by-step explanation:The remaining portion to be divided into 1/3 acre lots is the difference between the number of acres owned by the farmer and the number of arces used for the entrance. This difference is

= 24 arces - 6 arces

= 18 acres

These acres is to be divided into 1/3 arce then the number of 1/3 arce loits that will be available

Answer:

The support post positioned 23 feet far from the front of the house

Step-by-step explanation:

According to Pythagoras Theorem

(Hypotenuse)² = (Base)² + ( Perpendicular)²

We need to find Base so arranging the equation will give us

(Base)² = (Hypotenuse)² -  ( Perpendicular)²

Taking under root on both sides

Base =  √(Hypotenuse)² -  ( Perpendicular)²

Base =  √ (625 - 100)

Base = √525

Base = 23 feet
