Answer:
each ice coffee is $2.25
Step-by-step explanation:
13.50 - 9 = 4.50
4.50 / 2 = 2.25
Answer:
5
Step-by-step explanation:
plug that bad boy in and chug
36 + (-36) + 5
36 - 36 + 5
5
Answer:
It’s 5
Step-by-step explanation:
Because the new expression would be -6^2 + 6(-6) + 5 then u solve it...
36 + (-36) + 5
which is 5 have a great day!
Answer:
The 90% confidence interval for the mean test score is between 77.29 and 85.71.
Step-by-step explanation:
We have the standard deviation for the sample, so we use the t-distribution to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 25 - 1 = 24
90% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a confidence level of . So we have T = 2.064
The margin of error is:
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 81.5 - 4.21 = 77.29
The upper end of the interval is the sample mean added to M. So it is 81.5 + 4.21 = 85.71.
The 90% confidence interval for the mean test score is between 77.29 and 85.71.
K(8,11)
J(-3,1)
*7
*-6
*5
*-5
Answer:
(D)5
Step-by-step explanation:
Given the point J(-3,1) and K(8,11).
The line segment that divides the segment from J to K in any given ratio can be determined using the formula.
In the given case:
, m:n=2:3
Since we are to determine the y-coordinate of the point that divides JK into a ratio of 2:3, we have:
The y-coordinate of the point that divides the directed line segment from J to K into a ratio of 2:3 is 5.
The correct option is D.
Answer:
The answer is actually C(5) not D
Step-by-step explanation:
Answer:
Minimum: $25,200
Maximum: $44,800
Step-by-step explanation:
When the distribution is normal, we use 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 question:
What are the minimum and the maximum starting salaries of the middle 95% of the graduates
Minimum: 50 - (95/2) = 2.5th percentile.
Maximum: 50 + (95/2) = 97.5th percentile
2.5th percentile:
X when Z has a pvalue of 0.025. So X when Z = -1.96.
The minimum is $25,200
97.5th percentile:
X when Z has a pvalue of 0.975. So X when Z = 1.96.
The maximum is $44,800
