Answer:
the answer will be 86%
Step-by-step explanation:
first you (70x30=2100)
20x62=1240
2100-1240=860
and finally
you say 860÷10=86%
Answer:
0.68
Step-by-step explanation:
Given that :
P(trombone | snow) = 0.8 ;
P(trombone | no snow) = 0.5
P(snow) = 0.6
P(trombone) = P(trombone | snow) * p(snow) + P(trombone | no snow) * p(no snow)
P(no snow) = 1 - 0.6 = 0.4
Hence,
P(trombone) = P(trombone | snow) * p(snow) + P(trombone | no snow) * p(no snow)
P(trombone) = (0.8 * 0.6) + (0.5 * 0.4)
P(trombone) = 0.48 + 0.20
P(trombone) = 0.68
Step-by-step explanation:
it has 4 sides, all of whick are equal. Answer is 4*4, 16.

Answer:</h2>
(a) 6
(b) 9
<h2>
Step-by-step explanation:</h2>
The units of a whole number is the rightmost digit in the number. For example, if the number is <em>15678</em>, the units is <em>8</em> since that is the rightmost digit. Another example is <em>25795</em>. The units is <em>5.</em>
<em></em>
(a) To find the units of the square of -2346,
<em>i. First find the square of (-2346)</em>
(-2346)² = (-2346) x (-2346) = 5503716
<em>ii. Now find the rightmost digit.</em>
The rightmost digit of 5503716 is 6.
<em>Therefore, the units of the square of (-2346) is </em><em>6</em>

(b) To find the units of the square of -5677,
<em>i. First find the square of (-5677)</em>
(-5677)² = (-5677) x (-5677) = 32228329
<em>ii. Now find the rightmost digit.</em>
The rightmost digit of 32228329 is 9.
<em>Therefore, the units of the square of (-5677) is </em><em>9</em>

Answer:
<em>m</em> = 0
Step-by-step explanation:
slope can be found using the following equation:
<em>m </em>(slope) = (y₂ - y₁)/(x₂ - x₁)
Let:
(x₁ , y₁) = (-3 , -2)
(x₂ , y₂) = (1 , -2)
Plug in the corresponding numbers to the corresponding variables:
<em>m</em> = (y₂ - y₁)/(x₂ - x₁) = (-2 - (-2))/(1 - (-3))
Simplify:
<em>m</em> = (-2 - (-2))/(1 - (-3)) = (-2 (+2))/(1 +3) = (-2 + 2)/(1 + 3)
<em>m</em> = (-2 + 2)/(1 + 3) = (0)/(4)
<em>m </em>= 0/4 = 0
The slope of the line is 0.
