Answer:
Step-by-step explanation:
Given that a popcorn company builds a machine to fill 1 kg bags of popcorn. They test the first hundred bags filled and find that the bags have an average weight of 1,040 grams with a standard deviation of 25 grams.
i.e. Sample mean = 1040 and
Sample std dev s = 25 gm
Sample size n = 100
Hence by central limit theorem we have the sample mean follows a normal distribution with mean =1040 and std dev = s = 25 gm

Normal curve would be with mean 1040 and std deviatin 25
b) P(X>1115)
= 1-0.9987
=0.0013
i.e. 0.13% would receive a bag that had a weight greater than 1115 grams

Answer:</h2><h2>
True. A decimeter, a centimeter and a millimeter are all smaller than a meter.</h2>
Step-by-step explanation:
Convert all the units to metres for compariosn.
By metric conversion,
1 decimetre = 0.1 metre
1 centimetre = 0.01 metre
1 millimetre = 0.001 metre
Based on the above conversions, a decimeter, a centimeter and a millimeter are all smaller than a meter. Therefore the given statement is true.
Answer:
Step-by-step explanation:
5(-5)-2=-27
5(-2)-2= -12
5(1)-2=3
5(2)-2=8
5(3)-2=13
x g(x)
-5 -27
-2 -12
1 3
2 8
3 13
Step 1: 1/10 + 1/10 = 2/10
Step 2: 4/5 - 2/10
GCF: multiply both sides of 4/5 by 2 = 8/10
Step 3: 8/10 - 2-10 = 6/10
ANSWER: C <span>fraction 6 over 10, because fraction 4 over 5 minus 2 times fraction 1 over 10 equals fraction 4 over 5 minus fraction 2 over 10 </span>
