a) 4.2b) 4.5c) 4 and 7d) 6e) 75%

Explanation:

a) Mean

In the line plot, each x represents one student and the numbers below the line are the number of portable electronic devices (PED) in their home.

According to the the line plot:

1 student has 1 PED0 students has 2 PED2 students have 3 PED3 students have 4 PED2 students have 5 PED1 student has 6 PED3 students have 7 PED0 students have more than 7 PED

The mean is the sum of the PED divided by the number of students:

Count the x: 12Find the sum of the products of each number of PED and the corresponding number of students:

$Mean=\dfrac{1\times 1+2\times 3+3\times 4+2\times 5+3\times7}{12}$

$Mean=\dfrac{50}{12}\approx4.2$

b) Median

For every x (student), write the corresponding number of PED

1, 3, 3, 4, 4, 4, 5, 5, 6, 7, 7, 7

Since there are 12 data, an even number, the median is the average ot the two values in the center: 4 and 5:

$Median=\dfrac{4+5}{2}=4.5$

c) Mode

Mode is the number that has the greatest frequency; this is, that is repeated the most.

In this case, both 4 and 7 are repeated 3 times; thus, there are two modes: 4 and 7.

Modes: 4 and 7.

d) Range

Range is the difference between the largest value and the smallest value.

The largest value is 7 and the smallest value is 1.

Range = maximum value - minimum value

Range = 7 - 1 = 6

e) Percent of students that have more than 3 PED

Number of students with 4 PED: 3Number of students with 5 PED: 2Number of students with 6 PED: 1Number of students with 7 PED: 3

Total: 9

$Percent=\dfrac{\text{Number of students with more than 3 PED}}{\text{total number of students}}\times 100$

$Percent=\dfrac{9}{12}\times 100=75%$

Answer from: Quest

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
