A square lawn has a length of 8 feet and a width of 8 feet. Eight researchers each examine a randomly chosen

1 answer:

8 0

The best approximation to the number of seedlings that are at least 2 inches high in the entire lawn is:

D. 6,400

<h3>Total Seedlings Calculation.</h3>

To identify the total number of seedling in the entire lawn, first you must add all the seedling counted by the researchers:

Counted seedlings = 82 + 87 + 95 + 99 + 102 + 106 + 111 + 115
Counted seedlings = 697

Now, you must divide 697 in the number of regions taken by the researchers ( in this case were 8), this to obtain the average:

Average seedlings by region = $\frac{697}{8}$
Average seedlings by region = 87.125

Now, how we know, the entire lawn has a length of 8 feet and a width of 8 feet, it means 64 regions of one feet by one feet, by this reason, we multiply the average of seedlings by the whole regions in the lawn:

Number of seedlings in the lawn = 87.125 * 64
Number of seedlings in the lawn = 5576

Taking into account the average of seedlings is 5576, the best approximates of seedlings that are at least 2 inches high in the entire lawn is 6400.

Anything can solve this

Answer:

64.87° = 65°{ to the nearest degree}

Step-by-step explanation:

From the figure Catherine is standing 105m from the point B where the Ballon is; this description fits a= 105 m from the diagram.

Similarly Aisha is standing 95m from the point B where the Ballon is; this description fits c= 95 m from the diagram

A = ? ( The angle of elevation of Aisha towards the balloon)

C = 55°

From Sine rule

It states that the sine of an angle divided by its corresponding side is equal for all corresponding angles and sides along the triangle.

This is expressed mathematically as;

Sin A/ a= SinB/ b= SinC/c

We take the pairs of relevance;

Sin A/ a = SinC/c

There SinA = SinC/c × a

=Sin55/95 × 105

= 0.9053

A = Sin^(-1)[0.9053]

A = 64.87° = 65°{ to the nearest degree}

What is the y intercept of a line that has a slope of -3 and passes through the point (2,7)

Tom [10]

Y = mx + b
slope(m) = -3
(2,7)...x = 7 and y = 2
now we sub and fund b, the y int
2 = -3(7) + b
2 = -21 + b
2 + 21 = b
23 = b <== ur y int

List the integers within the interval <img src="https://tex.z-dn.net/?f=%20%208%20%5Cleqslant%20x%20%3C%2016" id="TexFormula

Vera_Pavlovna [14]

Answer:

list the integers within the interval

Step-by-step explanation:

Greater than or equal to 8, so 8 is part of this list.

Less than 16, so 16 is not in this list.

If you travel 40 miles at 45 miles per hour, how many minutes will that take you?

GenaCL600 [577]

Ok so im not good with words and math, but i am going to try my best to explain it. first you will take 45/60 which is the 45 miles per hour. next you will put it equal to 40/x. x is how many minutes. they are set equal to each other because they are the same ratio. (i honestly dont know why you cross multiply, but you just do). you then multiply 40*60 and 45*x. this gives you 2400=45x. you then divide both sides by 45 and get 53 1/3 minutes. or 53 minutes and 20 seconds
