Answer:
55.2
Step-by-step explanation:
-2.8+58
=58-2.8=55.2
now we dont write -55.2 becuase we check which no. is greater . we take the sign of greatest no. so in this case it is 58
so ans=55.2
Answer:
x ≈ - 6.74, 0.74
Step-by-step explanation:
x² + 6x - 5 = 0 ( add 5 to both sides )
x² + 6x = 5
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = 5 + 9
(x + 3)² = 14 ( take square root of both sides )
x + 3 = ±
( subtract 3 from both sides )
x = - 3 ± 
Then
x = - 3 -
≈ - 6.74 ( to the nearest hundredth )
x = - 3 +
≈ 0.74 ( to the nearest hundredth )
Answer:
1. True
2. False.
3. True.
Step-by-step explanation:
1. The total area within any continuous probability distribution is equal to 1.00: it is true because the maximum probability (value) is one (1), therefore, the total (maximum) area is also one (1).
<em>Hence, for continuous probability distribution: probability = area</em>.
2. For any continuous probability distribution, the probability, P(x), of any value of the random variable, X, can be computed: False because it has an infinite number of possible values, which can not be counted or uncountable.
<em>Hence, it cannot be computed. </em>
3. For any discrete probability distribution, the probability, P(x), of any value of the random variable, X, can be computed: True because it has a finite number of possible values, which are countable or can be counted.
<em>Hence, it can be computed. </em>
$30/ 3 sweatshirts = $10 /shirt
$ 10/shirt * 4 shirts = $40
It would cost $40
