The formula for the margin of error is

The critical value for 95% confidence interval is 1.96

The standard error is

To know which of the list of options will yield approximately the desired margin of error, we will have to calculate the margin of error with the following values

For 110 trees, n= 110, standard dev. =16

For 144 trees, n=144, standard dev=16

For 43 trees, n=43 , standard dev.=16

For 87 trees, n= 87, standard dev=16

Hence, from the above calculations, the most prefered is the sample size of 110 trees (because the margin of error of 2.9988 is approximately 3 )

Answer is 110 trees

Given:

The initial investment is, P = $720.

The rate of interest is, r = 7.8% = 0.078.

The number of years of investment is, t = 6 years.

Explanation:

The general formula to find the compound interest is,

Here, n represents the number of times compounded in a year. It is given that the amount is compounded monthly, so the value of n = 12.

To find total amount after 6 years:

Now, substitute the given values in the general equation.

Thus, the total amount earned is $1147.95.

To fnd interest amount:

Now, the amount of interest can be calculated as,

Hence, the interest amount earned is $427.95 and the total amount earned is $1147.95.

Slope of a parallel line: 6

Slope of a perpendicular line: -1/6

What is Slope ?

slope, The inclination of a line with respect to the horizontal is measured numerically. The ratio of the vertical to the horizontal distance between any two points on a line, ray, or line segment is known as its slope in analytical geometry ("slope equals rise over run").

Given equation,

y=6x-4

The equation of a line with slope  m  is given as:

y=mx+c

Rearranging the given equation:

y=(6)x+(-4)

By equating the equations we get,

m= 6

Which is slope of a parallel line

Now any parallel line would have the same slope.

And slope of a perpendicular line would be  −1/m.

i.e.  m(perpendicular)= -1/6

Hence, Slope of a parallel line is 6 and Slope of a perpendicular line is -1/6

As per the concept of probability, there are 7776 different lottery numbers are possible.

Probability:

Probability means the concept that is based on the possible chances of something to happen.

Given,

Lottery numbers in a particular state consist of 5 digits. Each lottery cube that is drawn/rolled has six sides, numbered 1-6.

Here we need to find how many different lottery numbers are possible.

Through the given question we know that,

The number of digits in a lottery ticket = 5

Side in cube = 6

So, in each time they will roll the dice 5 times to get one number.

So, the possible options of that event are,

For the first time we have 6 options

Second time we got 6 options

Third time also we got six option

Fourth time = 6 options

Fifth time = 6 options.

Therefore, it can be written as,

=> 6 x 6 x 6 x 6 x 6

=> 6⁵

=> 7776.

Therefore, there are 7776 different lottery numbers are possible.

The given statement is false: vertical angle do not depend on the line being parallel. A pair of vertical angles are always congruent.

Vertical angle:

Vertical angle means that the angles opposite each other when two lines cross.

Given,

Here we have the diagram and we also know that angle 7 is congruent to angle 5.

Now we need to find the given statement is true or not.

Through the given diagram, we have identified that, the eight angles will together form four pairs of corresponding angles.

Angles 1 and 5 constitutes one of the pairs.

We know that all the corresponding angles are congruent.

All angles that have the same position with regards to the parallel lines and the transversal are corresponding pairs e.g. 3 + 7, 4 + 8 and 2 + 6.

Through that we know that basically, the vertical angles are always congruent, which means that they are equal. So, it is not necessary for them to be parallel.

We are given;

Amount earned by athlete = $17,250,000

Number of games played = 80 Games

Number of minutes per game = 48 minutes

1) Amount earned per game = Amount earned by athlete/Number of games played = 17250000/80 = $215625 per game

2) If he played entire games for the entire minutes;

Amount earned per minute played = 17250000/(80 * 48)

Amount earned per minute played = $4492.1875

The cost of Apple A: $1.225

What is Weight?

The weight of an object is the force exerted on it by gravity. Some standard textbooks define weight as a vector quantity, the force of gravity acting on an object. Some define weight as a scalar quantity that is the magnitude of gravity.

Cost of the different types of the apple have been given as,

Apple A = costing $4.90 for 4 lb

Apple B = costing $1.00 for 10 oz

Apple C = costing $0.45 for 1/2 lb

For Apple A,

Since, cost of 4 lb = $4.90

Therefore, cost of 1 lb = 4.90/4

                                    = $1.225

For Apple B,

Since, 1 oz = 0.0625 lb

Therefore, 10 oz = 0.0625 × 10

                            = 0.625 lb

Since, cost of 10 oz = $1.00          

Therefore, cost of 0.625 lb = $1.00

And cost of 1 lb = 1/0.625

                          = $1.6

For Apple C,

Since, cost of 1/2 lb = $0.45

Therefore, cost of 1 lb = 0.45 × 2

                                   = $0.90

 Hence, Cost of Apple A will be the least with $1.225 per pound.

The safe load, L of a wooden a beam 3 in. wide 9 in. deep and 11 ft long of the same material support is 307.17

Analyzing the given conditions in the question, we get

The safe load, L is directly proportional to width (w) and square of depth (d²)

also,

L is inversely as length (l) i.e L = k/l

combining the above conditions, we get an equation as:

L = k(wd²/l)

now, for the first case we have been given

w = 8 in

d = 6 in

l = 10 ft

L = 1966 lbs

thus,

1966 lb = k ((8 × 6²)/10)

or

k = 68.26 lbs/(ft.in³)  

Now,

Using the calculated value of k to calculate the value of L in the second case  

in the second case, we have

w = 3 in

d =9 in

l = 11 ft

Final Safe load L' =  68.26 × (6 × 3²/12)

or

L' =307.17 lb

Therefore, The safe load, L of a wooden a beam 3 in. wide 9 in. deep and 11 ft long of the same material support is 307.17
