Answer:
At least 6907 people.
Step-by-step explanation:
Population std deviation = sigma= 10.6
Since population std deviation is known, we can use normal probability table to get sample size from confidence interval.
The sample mean weight loss is within 0.25 lb of the true population mean.
Hence margin of error < 0.25
Margin of error = z critical (std dev/n) where n = sample size
Z critical for 95% = 1.96
Hence 0.25 >1.96(10.6)/sq rt n
Simplify to get
sq rt n > 1.96(10.6)/0.25 = 83.104
Square both the sides to get
n > 83.104 square = 6906.27
i.e. sample size should be atleast 6907.
Answer:
B
Step-by-step explanation:
your answer should be B because isosceles triangles always have 2 equal sides :))
Find the greatest common factor
in this case it would be 8, so she'd be able to make 8 packets maximum
Step-by-step explanation:
when choosing a sample everyone must have an equal chance of getting picked
Hello there!
The correct answer is option A, because:
4(t - 6)
Use the distributive property
(4)(t) + (4)(-6)
So yeah, this is how the distributive property works.
Option A is the only option that works with the distributive property.
Let me know if you have questions about the answer. As always, it is my pleasure to help students like you!
