A landscaper wants to find the answer to the question "How much time do people in Raleigh, North Carolina, spend doing yard work in one week?" He asks the owners of all 120 houses in a Raleigh neighborhood. Which best describes the accuracy of the results of the survey? The survey results will be inaccurate because lawns in one neighborhood do not represent all types of lawns in a large city. The survey results will be inaccurate because the entire population of Raleigh should have been surveyed. The survey results will be accurate because the sample represents the population and the population is the target of the survey. The survey results will be accurate because the sample size was large enough to represent the population.

Answer:

4/9 are boys

Step-by-step explanation:

BD bisect AC

Option B is the correct answer.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

From the figure,

FA is perpendicular to BC.

CFA is a right angle.

We see that BD bisects AC such that AD = CD.

Thus,

BD bisects AC

The maximum area covered will be 9 ft².

The region that a circle occupies in a two-dimensional space is known as the area of the circle.

The area of circle is -

A = πr²

Given:

The chemistry teacher decides to use chalk paint to cover a circular portion of a wall in the science lab.

If the greatest distance across the circle is is 3 feet.

We can write the maximum area covered as -

A = πr²

A = 3.14 x 3 x 3

A = 9 ft²  {approx.}

So, the maximum area covered will be 9 ft².

Answer:

33/100

Step-by-step explanation:

======================================================

Explanation:

We have 6 green out of 6+6+6 = 18 total

The probability of getting green is 6/18 = 1/3.

After selecting that green jelly bean and not putting it back, we have 6-1 = 5 green out of 18-1 = 17 total.

The probability of selecting another green is 5/17.

Multiply the two fractions 1/3 and 5/17

(1/3)*(5/17) = (1*5)/(3*17) = 5/51

The probability of selecting two greens in a row is 5/51 where we do not put the first selection back. We also do not replace the green jelly bean with some other identical copy.

Note: 5/51 = 0.098039 approximately

Step-by-step explanation:

Answer:

0.0381

Step-by-step explanation:

This is a binomial probability distribution problem. Thus;

p = 10% = 0.1

We are told that A random sample of 8 light bulbs are chosen and tested. Thus, n = 8

We want to find the probability that at least 3 are defective. This will be;

P(X ≥ 3) = P(3) + P(4) + P(5) + P(6) + P(7) + P(8)

P(X = x) = C(n, x) × p^(x) × (1 - p)^(n - x)

Thus;

P(3) = C(8, 3) × 0.1³ × (1 - 0.1)^(8 - 3)

P(3) = C(8, 3) × 0.1³ × 0.9^(5)

P(3) = 0.03306744

Repeating this same procedure, we have;

P(4) = 0.0045927

P(5) = 0.00040824

P(6) = 0.00002268

P(7) = 0.00000072

P(8) = 0.00000001

Thus;

P(X ≥ 3) = 0.03306744 + 0.0045927 + 0.00040824 + 0.00002268 + 0.00000072 + 0.00000001 = 0.03809179

3 x 6 = 18

2. Get answer of 18

18 inches

Answer:

118

Step-by-step explanation:

If angle A is 62 degrees, then angle D is 62 degrees. 62+62=124, and 360-124 is 236 (360 is the total interior angles of any quadrilateral). Then, 236/2=118. You divide it by two because you are looking for angles B and C separately.

Answer:

28

Step-by-step explanation:

100 - 72 = 28

Answer:

Step-by-step explanation:

We know that when two lines meet or intersect, we get a linear pair of angles.

Linear pairs are basically two adjacent angles that form a line.

The measure of two adjacent angles forming a straight line is 180, meaning they are supplementary.

We are given that <1 and <2 forms a linear pair, and

m∠1 = 4m∠2

It means the angle ∠1 is 4 times the measure of angle ∠2.

Let the angle ∠1 be = x

As the angle 1 is 4 times the measure of angle ∠2, so

The angle 2 will be = 4x

As <1 and <2 forms a linear pair, thus the measure of the sum of <1 and <2 will be 180°, so

x + 4x = 180

5x = 180

divide both sides by 5

5x/5 = 180/5

x = 36°

Answer: 1.8 miles per week

Step-by-step explanation:

The European lynx travelled for 301 days and in that time covered a distance of 77.8 miles.

Convert the number of days to weeks:

= 301 / 7

= 43 weeks

If it travelled 77.8 miles in 43 weeks, its speed was:

= 77.8 / 43

= 1.8 miles per week

multiply both sides by 5 to make x the subject

x=t/5

Answer: 5x=t

              x=t/5(Ans)

Step-by-step explanation:In order to make x the subject,We can start by removing the 5 that is multiplied with x.To do that divide both sides with 5. 5x divided by 5 is x and t divided by 5 is t/5.Therefore the final answer after making x the subject will be x=t/5.

Answer:

600, 150

Step-by-step explanation:

Kyle is x

ken is y

x = 4y

x+y = 750

replace x with 4y

4y + y = 750

5y = 750

y = 150

so ken earned 150

x + 150 = 750

x = 600

so Kyle earned 600
