The answer is 15 cm. Hope I could be of help! ; )
p = -3
Step-by-step explanation:
-2p-4=2
add 4 both sides
-2p-4+4=2+4
-2p=6
divide -2 both sides
-2p/-2=6/-2
p = -3
hope it's helpful ❤❤❤
THANK YOU.
Answer: 30 minutes
Step-by-step explanation: First we can reduce the fraction 2/4 by dividing the numerator and the denominator by the greatest common factor of 2 and 4.
Since the factors of 2 are 1 and 2 and the factors of 4 are 1, 2, and 4, the greatest common factor of 2 and 4 is 2. So we divide the numerator and the denominator of 2/4 by 2 and we get the equivalent fraction 1/2.
Now we can change the question to say <em>1/2 of an hour is how many minutes?</em>
We know that 1 hour is equivalent to 60 minutes so half of 1 hour would be 30 minutes.
Therefore, 2/4 of an hour is 30 minutes.
Answer:
7.3% percentage of the bearings produced will not be acceptable.
Step-by-step explanation:
Consider the provided information.
Average diameter of the bearings it produces is .500 inches. A bearing is acceptable if its diameter is within .004 inches of this target value.
Let X is the normal random variable which represents the diameter of bearing.
Thus, 0.500-0.004<X<0.500+0.004
0.496<X<0.504
The bearings have normally distributed diameters with mean value .499 inches and standard deviation .002 inches.
Use the Z score formula: 
Therefore
Now use the standard normal table and determine the probability of that a ball bearing will be acceptable.
We need to find the percentage of the bearings produced will not be acceptable.
So subtract it from 1 as shown.
1-0.9270=0.073
Hence, 7.3% percentage of the bearings produced will not be acceptable.
Answer:
1.) Proportion is about the ratio of part of something out of a whole. Percentage is similar because it tells you the ratio of something out of a whole.
2.) No, tip amount is more than what the waiter usually receives
Step-by-step explanation:
2.) The amount of tip the waiter receives = 20% of total money.
therefore 20% of 47.20 = 20/100 * 47.20 = $9.44;
$11 > $9.44
