Answer:
4x10=40-2=38
38% = 0.38 in decimal form. Percent means 'per 100'. So, 38% means 38 per 100 or simply 38/100. If you divide 38 by 100, you'll get 0.38 (a decimal number).
(hope this helps can i plz have brainlist :D hehe)

Answer:
1.6 Gallons Per Day
Step-by-step explanation:
first you got to do 2/3 which is 0.666666 then i multiply 0.66666 by 2 so it at 20 hours which is 1.333333 then i did 0.666666 and divided it by 10 which is 0.066666then i multiply 0.066... by 4 which is 0.2666666 then i added 0.2666666 and 1.3333333 together and it made 1.6
Answer:
y = -9
Step-by-step explanation:
Y = -x +6
the -x is because the slope of the line goes down 1 over 1, and -x is the same as -1x
the +6 is for the y intercept, at (0,6)
Answer:
See the explantion below
Step-by-step explanation:
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Assuming the X follows a normal distribution
We know that the margin of error for a confidence interval is given by:
(1)
If we see the formula (1) at the same confidence level, for example 95% and with the same sample size the margin of error just depends of the deviation. If the population deviation for population A is higher than the population deviation for B then A will have more margin of error than B.
On the other case if the deviation for population A is lower than the deviation for population B, then we will have less margin of error for population A than population B.
And the other possible case if both population have the same deviation, then both have equal margin of error.
