C because in order of operations you would use PEMDAS, there’s no parentheses or exponents so you’d go to multiplication and division by which ever comes first in the problem.
Step-by-step explanation:
3x + 8y + 5
The true statements
5 is a constant
3x + 8y + 5 is written as a sum of three terms
3x and 5 are like terms
if we take the $15.06 and take away the $5.00 (as its a discount) which leaves us with $10.06 and then add the $20.00 which gives us the final answer of $20.06
Hope this helps
Answer:
By the Empirical Rule, 99.7% of the students have grade point averages that are between 1.28 and 3.8.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed(bell-shaped) random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 2.54
Standard deviation = 0.42.
Between 1.28 and 3.8?
1.28 = 2.54 - 3*0.42
So 1.28 is 3 standard deviations below the mean
3.8 = 2.54 + 3*0.42
So 3.8 is 3 standard deviations above the mean
By the Empirical Rule, 99.7% of the students have grade point averages that are between 1.28 and 3.8.
