There is a 3% chance of each light bulb being defective, and we only want 5 of them to be defective. The chance is then:
Or this really small number: 1.13474853e-8
Answer:
900 square feet
Step-by-step explanation:
Answer:
Since we have the information for Angles 1 and 3, and they are vertical, we can set them equal to each other. Once we have done this we can find the measures of them combined, and subtract it from 360 in order to only have the measure of 2 and its vertical angle. Finally, all we need to do now is divide the remaining measure by 2, and this will give us the measure of angle 2.
Angle 1=Angle 3
4x+30=2x+48
2x+30=48
2x=18
x=9
Angle 1=4(9)+30
Angle 1=36+30
Angle 1=66
Angle 1=Angle 3
Angle 1+ Angle 3=132
360-132=228
228/2=114
Angle 2= 114
Answer:
A
Step-by-step explanation:
x + y = 4a + 7
x - y = 2a + 5
In both equations, make x the subject of the formula
x = 4a + 7 - y equation 1
x = 2a + 5 + y equation 2
Subtract equation 2 from equation 1
2a + 2 -2y
= 2a + 2
Answer:
132
Step-by-step explanation:
We use the volume formula for a cylinder which is V=πr2h, divide the diameter by 2 to get the radius and fill in our formula to get 131.88, finally round to 132.
