Answer:
43.49
Step-by-step explanation:
let his normal hourly rate be x
16x+7x/2=848
39x/2=848
x=848 ÷ 39/2
=43.48717
Answer:
The probability that carbon emissions from the factory are within the permissible level and the test predicts the opposite to be true is 19.338% (Rounding to the next thousandth place)
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Probability that carbon emissions from the company’s factory exceed the permissible level = 35% = 0.35
Accuracy of the test of emissions level = 85% = 0.85
2. The probability that carbon emissions from the factory are within the permissible level and the test predicts the opposite to be true is?
These two events, carbon emissions from the company’s factory and the accuracy of the test are independent events, therefore:
Probability that carbon emissions from the factory are within the permissible level = 1 - 0.35 = 0.65
Probability that the test predicts the opposite to be true = 0..35 * 0.85 = 0.2975 (The opposite is that the carbon emissions from the company exceed the permissible level)
Probability that carbon emissions from the factory are within the permissible level and the test predicts the opposite to be true is:
0.65 * 0.2975 = 0.193375
The probability that carbon emissions from the factory are within the permissible level and the test predicts the opposite to be true is 19.338% (Rounding to the next thousandth place

Answer:
600
Step-by-step explanation:
Given,
Numbers are 825 and 213.
If the number are equal or greater than 50 then one number will be rounded up. if the number is less then it will rounded down.
Like in this case 25 and 13 are less than 50 so, they will not rounded up.
825 will be rounded to 800.
213 will be rounded to 200.
Subtraction of number
= 800 - 200 = 600
Answer:
x = 40
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the triangle on the left and calculate the third angle
Subtract the sum of the 2 angles from 180
third angle = 180° - (75 + 50)° = 180° - 125° = 55°
Consider the triangle on the right
The third angle = 55° ( vertical angles )
Subtract the sum of the 2 angles from 180
x = 180 - (55 + 85) = 180 - 140 = 40
The three integers are 5,17 and -10
Step-by-step explanation:
Let x, y and z be three integers then
'The sum of the first and second integers exceeds the third by 32'
The third integer is 15 less than the first.
From Eqn 2:
Subtracting Eqn 1 from eqn 2
Dividing both sides by -2
Putting z=-10 in Eqn 3
Putting x=5 and z=-10 in Eqn 1
Hence,
The three integers are 5,17 and -10
