See Explanation

Step-by-step explanation:

A positive integer is a perfect square if it can be expressed as the product of two same positive integers.

Any number that cannot be written this way is a non-perfect square.

Since the integers are not presented, we will quickly examine the perfect squares between 1 and 50.

The perfect squares are: 1,4,9,16,25,36 and 49.

1=1 X 1
4=2 X 2
9=3 X 3
16 =4 X 4
25 =5 X 5
36 =6 X 6
49 =7 X 7

Every other positive integer in the numbers 1-50 apart from those listed above is a non-perfect square.

Step-by-step explanation:

look at the picture !

she has to paint actually 6 rectangles :

the 3 tops of the 3 stairs.

and the 3 vertical front boards (the front of each step of the stairs).

what is the area of these rectangles ? summing up all 6 - that is the surface area to be painted.

each top rectangle is clearly

82×19 (19 cm deep) = 1558 cm²

each front board is

82×12 (12 cm high) = 984 cm²

so, in total we have

3×1558 + 3×984 = 4674 + 2952 = 7626 cm²

as surface area to be painted.

A book can be classified as either non dash fiction or fiction. Suppose that 87% of books are classified as fiction. (a) Two b

Mnenie [13.5K]

Answer:

0.7569, 0.5729,0.4371

Step-by-step explanation:

Given that the books are of only two types either non dash fiction or fiction.

Also probability of selecting a fiction = 0.87 = p

X - no of books fiction selected is binomial with p = 0.87 and n =2

(since each trial is independent of the other and there are only two trials)

a) the probability that both books are fiction=

$P(X=2) = 0.87^2 = \\0.7569$

b) Here n =4 with same p.

$P(X=4) =0.87^4 \\= 0.5729$

c) Prob atleast one is non dash fiction = $P(X< 4)\\= 1-P(X=4)\\=1-0.87^4\\=0.4371$

This is not unusual since 0.4371 probability is not nearer to 0 it is almost half.

Mixed equations. Show work please

Solving:

1)

-58 - 6x = 42 + 4x
Pass the numbers with letter to the left and the numbers without letter to the right, changing the signal as they change sides.
- 6x - 4x = 42 + 58
- 10x = 100 simplify by (-1)
10x = - 100
 $x = \frac{-100}{10}$
$\boxed{x = - 10}$ 

2)

37 + 5x = -2x - 33
Pass the numbers with letter to the left and the numbers without letter to the right, changing the signal as they change sides.
5x + 2x = - 33 - 37
7x = - 70
 $x = \frac{-70}{7}$
$\boxed{x = - 10}$

3)

27 - 9x = -6x - 39
Pass the numbers with letter to the left and the numbers without letter to the right, changing the signal as they change sides.
- 9x + 6x = - 39 - 27
- 3x = - 66 simplify by (-1)
3x = 66
$x = \frac{66}{3}$
$\boxed{x = 22}$
