1.  6+1+2+4+4+5=22.

Correct

2. 1 cm=5 ft. 6*5=30(2 times). 1*5=5. 2*5=10. 4*5=20(2 times). 

30+30+5+10+20+20=115.

Your answer to the first one is incorrect.

We can cut the plan into two figures, a rectangle with side lengths of 4 cm and 5 cm and a rectangle with side lengths of 1 and 2 cm.

Perimeter of a Rectangle:

P = 2(l + w)

P = 2(4 + 5)

P = 2(9)

P = 18

Perimeter of a Rectangle:

P = 2(l + w)

P = 2(2 + 1)

P = 2(3)

P = 6

Add up the perimeters:

18 + 6 = 24

So the total perimeter is 24.

For the 2nd one, your answer is also incorrect.

We multiply 5 to the perimeter of the plans:

5 * 24 = 120

Not sure what the third one is asking.

For the fourth one we just multiply 'k' to the perimeter:

24 * k = 24k

Fiona recorded the mean math exam grade for six random samples of students from the entire seventh-grade class. Sample Sample Me
Charra [1.4K]

The reason why Fiona cannot make a valid prediction based on the mean of the population is that the variation of Fiona’s samples is too large.

<h3>Why can't Fiona use the means she recorded?</h3><h3 />

Mean is quite sensitive to outliers so it is best used when the variation between variables is not too much.

In Fiona's case, there variation is quite high with high variable of 95 compared to a low value of 45.
