For a class project, Henry needs to know how many students at M College think that
grandymaker [24]

The estimated number of students at the M College who agree climate change is a serious issue is  1759

The percentage of total students is 59.42%

The method used can be biased.

<h3>How many students believe climate change is a serious issue?</h3>

The students surveyed are the sample while the students in the M College are the population. A population is the party of interest in an experiment. A population consists of all the members of the group. A sample is a smaller group of the population.

The limitation of using a sample to estimate for the population is that the sample might be a biased estimate of the population. If the sample is biased, the result of the experiment would be inaccurate.

Estimated number of students at M College = (sample that agree that climate change is a serious problem / total number of people surveyed) x number of students

(205 / 345) x 2960 = 1759

Percentage = (1759 / 2960) x 100 = 59.42%

The side of a triangles are 8cm,12cm,17cm.find its perimeter and its are by using herons formula
Novay_Z [31]

Answer:

see explanation

Step-by-step explanation:

The perimeter is the sum of the 3 sides, that is

perimeter = 8 + 12 + 17 = 37 cm

To use Heron's formula for area (A)

A = \sqrt{s(s-a)(s-b)(s-c)}

where a, b and c are the lengths of sides and s the semi perimeter

s = 37 ÷ 2 = 18.5

let a = 8, b = 12 and c = 17, then

A = \sqrt{18.5(18.5-8)(18.5-12)(18.5-17)}

   = \sqrt{18.5(10.5)(6.5)(1.5)}

   = \sqrt{1893.9375} ≈ 43.52 cm² ( to 2 dec. places )
