Which of the following is a true statement?A. All squares are rectangles
B. All rectangles are squares
C. All rhombuses are squares

Answers

Answer 1

Answer:
A rectangle is a parallelogram with interior right angles.
That description applies very satisfactorily to squares.
A square is a special kind of rectangle, so all squares are rectangles.

(All squares are rhombuses, parallelograms, and quadrilaterals too.)

Answer 2

Answer:

Answer: Option 'A' is correct and true.

Step-by-step explanation:

Square is the quadrilateral whose all sides are equal and all angles are right angles and

Rectangle is the quadrilateral whose opposite sides are equal and all angles are right angles.

so, All squares are rectangle as it satisfied the angle property of rectangle and opposite sides of square is also equal.

But all rectangles can't be a square as in rectangle all sides are not equal.

And all rhombus can't be squares as in square all angles are of right angles but rhombus does not possess such property at all.

Hence, Option 'A' is correct and true.

The following data show the height, in inches, of 11 different plants in a garden: 9 4 10 9 5 2 22 10 3 3 5 After removing the outlier, what does the mean absolute deviation of this data set represent?

Answers

The outlier is the obviously different data among the whole group of data points. In this case, the outlier is 22. When you find the mean, you only use the data points without the outlier. Therefore,

Mean = (9+4+10+9+5+2+10+3+3+5)/10 = 6

Then, the mean absolute deviation is

∑(x-mean)^2/n, where x is every single data point and n is the number of data points which is equal to 10

|9-6|+|4-6|+|10-6|+|9-6|+|5-6|+|2-6|+|10-6|+|3-6|+|3-6|+|5-6| = 28

Then,

Mean Absolute Deviation (MAD) = 28/10 = 2.8

This is the average distance of the data from the mean.

How can you use a rate to compare the costs of 2 boxes of cereal that are different sizes

Answers

You'd have to use their weights and work out price/gram or you could alternately work out the volume (this is pretty hard because most cereals come in very awkward plastic containers so I recommend price/gram).

So just do this for both boxes:
Price / Mass (in grams)

The one with the greater value will be the less cost-effective method.

the suntracker grows at a rate of 2.5 CM per day after the first 60 days.If this sunflower is 195 cm tall when it is 60 days old witer a expression to represent suntrackers height after 22 days or when it is 82 days old exspain how you found your answer, other sunflower is 235 cm

Answers

Given:
height at 60 days old - 195cm
height after 60 days old - 2.5cm per day

total height = 195 cm + 2.5cm(x - 60)
x = day measured

22 days old

total height = 195cm + 2.5cm(22-60)
t.h = 195cm + 2.5cm(-38)
t.h = 195cm - 95cm
t.h = 100 cm

82 days old

total height = 195cm + 2.5cm(x-60)
t.h = 195cm + 2.5cm(82-60)
t.h = 195cm + 2.5cm(22)
t.h = 195cm + 55cm
t.h = 250cm
