Answer:
32 large lemonades
Step-by-step explanation:
4 gallons = 512 ounces
512 ounces / 16 ounces
= 32 large lemonades.
Answer:
The numerical limits for a B grade is between 81 and 89.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
B: Scores below the top 13% and above the bottom 56%
Below the top 13%:
Below the 100-13 = 87th percentile. So below the value of X when Z has a pvalue of 0.87. So below X when Z = 1.127. So
Above the bottom 56:
Above the 56th percentile, so above the value of X when Z has a pvalue of 0.56. So above X when Z = 0.15. So
The numerical limits for a B grade is between 81 and 89.
The graph with the line going through (0,0) with a slope of 2. This is because for every 1 hour, she has 2 bags of leaves.
The y number goes up by 2. 0 hours, 0 bags. 1 hour, 2 bags. 2 hours, 4 bags. And so on.
(0,0), (1,2), (2,4), (3,6)...
Answer:
d. We are 95% sure that between 52% and 68% of all adults in this city will root for North High School.
Step-by-step explanation:
A confidence interval of a proportion p% at the x% level with m% margin of error means that:
We are x% sure that the true mean of the population is in the interval from (p-x)% to (p+x)%.
So the correct answer is:
d. We are 95% sure that between 52% and 68% of all adults in this city will root for North High School.
Answer:
Line d y = -3x -3
Line e y = -3x -1
Line f y= -3x+2
To write the equation of a line, you need the slope and the y-intercept. The slope of each line is -3. Find the y-intercept on the graph and then substitute it into the equation y = mx+b for b.
Line d has y-intercept (0,-3)
y = -3x -3
Line e has y-intercept (0,-1)
y = -3x -1
Line f has y-intercept (0,2)
y= -3x+2
