Answer:

Step-by-step explanation:

All parallelograms have diagonals which bisect each other. This means the diagonals intersect and create equal lengths.

5y = 3x + 6

8x - 2 = 4x

Solve for x using 8x - 2 = 4x. Then substitute x into the other equation.

8x - 2 = 4x

-2 = -4x

1/2 = x

Substitute x = 1/2.

5y = 3(1/2) + 6

5y = 3/2 + 6

5y = 3/2 + 12/2

5y = 15/2

y = 15/10

y = 3/2 or 1.5

timofeeve [1]

Answer:

(a) The average grade point is 2.5.

(b) The relative frequency table is show below.

Step-by-step explanation:

The given data set is

4, 4, 4, 3, 3, 3, 1, 1, 1, 1

(a)

The average grade point is

$Average=\frac{\sum x}{n}$

$Average=\frac{4+4+4+3+3+3+1+1+1+1}{10}$

$Average=2.5$

Therefore the average grade point is 2.5.

(b)

$\text{Relative frequency}=\frac{\text{Frequency of number}}{\text{Total frequency}}$

The relative frequency table is show below:

x f Relative frequency

4 3 $\frac{3}{10}=0.3$

3 3 $\frac{3}{10}=0.3$

1 4 $\frac{4}{10}=0.4$

(c)

Mean of the relative frequency distribution is

$Average=\frac{0.3+0.3+0.4}{3}$

$Average=0.3333$

Therefore the mean of the relative frequency distribution is 0.3333.

In order to estimate the average time spent per student on the computer terminals at a local university, data were collected for

d1i1m1o1n [39]

Answer: option D

Step-by-step explanation:

The formulae for standard error = standard deviation/√n

But population standard deviation = 1.8 and sample size = n = 81

Standard error = 1.8/√81 = 1.8/9 = 0.2
