An 80% confidence interval for a proportion is found to be (0.52, 0.58). What is the sample proportion?

Answer: The mode is 92.

Step-by-step explanation: The mode means the number that comes up the most times, and 92 is there twice, and all the others once so 92 is the a mode.

Answer:

[tex]y = - 3[/tex]

Step-by-step explanation:

[tex]5(y + \frac{2}{5} ) = - 13 \\ 5y + \frac{10}{5} = - 13 \\ 5y + 2 = - 13 \\ 5y = - 13 - 2 \\ 5y = - 15 \\ \frac{5y}{5} = \frac{ - 15}{5} \\ y = - 3[/tex]

Step-by-step explanation:

Answer:

1.074 acres are there in this building lot.

2 houses will be allowed to build on this lot.

Step-by-step explanation:

Dimensions of the building lot are 260 ft [tex]\times[/tex] 180 ft.

The building lot is rectangular in shape.

Area of the building lot (Length [tex]\times[/tex] Width) is:

[tex]260 \times 180 \\\Rightarrow 46800\ ft^2[/tex]

It is given that:

[tex]43,560\ ft^2 = 1\ acre\\1\ ft^2 = \dfrac{1}{43560\ acres}\\46800\ ft^2 = \dfrac{1}{43560} \times 46800\ acres\\\Rightarrow 1.074\ acres[/tex]

So, 1.074 acres are there in this building lot.

A house is build on [tex]\frac{1}{2}[/tex] acres and we have ~1 acre of land in the building lot.

So, town will allow to build 2 houses on this land.

Answer:

279 patches can be made.

Step-by-step explanation:

Evaluate the total area of the rectangular piece of fabric, therefore:

Area= l*w = 15*9=135

There are 31 pieces, so the total area is 135* 31 =4,185 square centimeters.

Evaluate the number of triangles that can be made dividing the total area by the area of 1 triangular piece, therefore:

n= 4,185/15=279

So the answer is 279 triangles can be made.

n + n - 0.18n

We can rewrite it as

2n - 0.18n

And if we solve it

(2 - 0.18)n = 1.82n

So the equivalente expression is B.

I think it would require 100 workers since 1 worker digs up 1 yard.

Hope this helps.

It is found that 100 workers are needed to dig a 100 yards long in 100 hours

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that Five workers dig a trench 5 yards long in 5 hours.

We need to find workers are needed to dig a 100 yards long in 100 hours.

5 workers dig , 5 yards long = 5 hours.

1 yards long = 1 hours.

Thus, 100 workers dig a 100 yards long in 100 hours.

Answer:

4

Step-by-step explanation:

Since ABC is similar to ADE by AA (the triangles share angle A and a right angle), they must have equal proportions. Therefore:

[tex]\dfrac{x}{4}=\dfrac{12}{4+8}[/tex]

Therefore, x=4. Hope this helps!

Answer:

x=4

Step-by-step explanation:

The triangles are similar so we can use ratios to solve

x             4

------ = ----------

12         (4+8)

Using cross products

12x = 4*12

Divide each side by 12

12x/12 = 48/12

x=4

Answer:

y = e²x

Step-by-step explanation:

Using the rules of logarithms

log y - log x = log ([tex]\frac{y}{x}[/tex] )

[tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]

Given

ln(y) = ln(x) + 2 ( subtract ln(x) from both sides )

ln(y) - ln(x) = 2

ln ([tex]\frac{y}{x}[/tex] ) = 2

[tex]\frac{y}{x}[/tex] = e² ( multiply both sides by x )

y = e²x

Answer:

The distance between the 6th and 10th seat is approximately 126m

Step-by-step explanation:

First of all, we will need to calculate the circumference of the circular fair ride.

which the formula is  

[tex]2\pi r= 2 \times \pi \times 60 \\\\=377m[/tex]

The circumference of the circle is 377m

At this point, we will have to take note that the pods are equally spaced.

To get the distance between the sixth pod and the tenth pod, we will have to use the principle of fractions of a whole.

There are 12 seats in total, the distance between the 6th and tenth seat is 4 seats. Expressing this distance in terms of seats, as a fraction is 4/12 equally spaced seats.

This ratio can be related to the circumference of the circle as

[tex]= \frac{4}{12} \times377\\\\=125.66m \approx 126m[/tex]

Therefore, the distance between the 6th and 10th seat is approximately 126m

To write the equation of line in y = mx + b form, we need

to identify the slope of the line and the y-intercept.

I would start by setting up a coordinate

system and plotting both points.

I have shown this below.

Let's start with our first point, (3, -1) which we call point A.

Now our second point, (6, 1) which we call point B.

To get from point A to point B, we rise 2 units and run 3 units.

So we know that our slope is 2/3.

However, we need the y-intercept.

Remember, this is the point where the line crosses the y-axis.

Since point B is farther from y-axis,

we need to go in the other direction.

So starting at point A, we go down 2 and to the left 3.

Remember, -2/-3 is 2/3 since a negative/negative = positive.

Now plot point C.

Notice that point C is on the y-axis.

It has the coordinates (0,-3).

Now we know our slope and y-intercept.

So our equation reads 2/3x - 3.

The slope is positive since the line is going up.
