Answer:
Small fish= 7
Big fish= 21/4 (so she'll get 5 big fish)
Step-by-step explanation:
With the problem, there are two equations, one for the cost, and one for the amount of water. For the first equation, Alaina can spend 70 dollars and the fish cost 8 and 3 dollars so the equation is 70=8b+4s (s for small and b for big). Then for the second equation there are 14 available gallons and the fish require 2 and .5 gallons so 14=2b+0.5s. Then you just solve the system of equations.
Answer:
If the confidence level is increased from 90% to 99% for an SRS of size n , the width of the confidence interval for the mean μ will <u>increase</u>.
Step-by-step explanation:
We have been given an incomplete statement. We are supposed to complete the given statement.
If the confidence level is increased from 90% to 99% for an SRS of size n , the width of the confidence interval for the mean μ will:
We know that when confidence level decreases from a value to a lower value, then the confidence interval for the mean decreases.
When confidence level increases from a value to a higher value, then the confidence interval for the mean increases.
When we will increase the confidence level from 90% to 99%, the width of the confidence interval for the mean will also increase, so it will become wider.
Therefore, the correct word for our given statement is increase.
Answer:
B
Step-by-step explanation:
The mean is calculated as
mean =
=
= = 4.2 Kg → B
1.79% This is found by dividing 1,400,000 by 25 which gives 56,000. Then divide 1 by 56,000
