The scientific notation:

a\cdot 10^k where 1\leq a < 10 and k\in\mathbb{Z}

(3.1\cdot10^5)(2.2\cdot10^7)=(3.1)(2.2)(10^5\cdot10^7)\\\\=6.82\cdot10^{5+7}=6.82\cdot10^{12}

Fist add 203 and 220 and you get 423.
Then add all the dvds 11+3 and you get 14 then
Next add all the video games 11+14 and you get 25
next divide 25 from 423 then you get 16.92
then divide the dvds 423 divided by 14 and you get 30.21

Please help, would be greatful :)

Answer:

1. a = 21°

2. b = 70°

3. c = 89°

Step-by-step explanation:

1. Determination of the value of a.

a = 21° (vertically opposite angles are equal)

2. Determination of the value of b.

From the question given above,

110 + b = 180 (sum of angles on a straight line)

Collect like terms

b = 180 – 110

b = 70°

3. Determination of the value of c.

a + b + c = 180 (sum of angles in a triangle)

a = 21°

b = 70°

c =?

21 + 70 + c = 180

91 + c = 180

Collect like terms

c = 180 – 91

c = 89°

What is the range of the relation in the table below? x y –2 0 –1 2 0 4 1 2 2 0 range: range: range: range:
melomori [17]

The range of the relation in the table is {0 , 2 , 4}

Step-by-step explanation:

A relation is a relationship between sets of values, where

  • The domain is the set of all first elements of ordered pairs x-coordinates
  • The range is the set of all second elements of ordered pairs y-coordinates

The table:

→  x  :  -2  :  -1  :  0  :  1  :  2

→  y  :  0   :  2  :  4  :  2  :  0

From the table the ordered pairs are:

(-2 , 0) , (-1 , 2) , (0 , 4) , (1 , 2) , (2 , 0)

∵ The range of the relation is the values of y

∵ The values of y in the ordered pairs are 0 , 2 , 4 , 2 , 0

∵ The range is the set of values of y

- In the set of numbers we don't repeat the numbers

∴ The range is {0 , 2 , 4}

The range of the relation in the table is {0 , 2 , 4}

Dimas [21]

Answer:  <u>0.4032</u>

<em>If it served you, give me 5 stars please, thank you!</em>

<em>________________________________________________________</em>

solution:-

given that p = 0.30 , n = 17

p(x > 5) = 1 - p(x ≤ 5)

= 1 - (p(x = 5) + p(x = 4)+ p(x = 3)+ + p(x = 2)+ p(x = 1)+ p(x = 0))

= 1 - (0.2081+0.1868+0.1245+0.0581+0.0169+0.0023)

= 1 - 0.5968

= 0.4032
