Answer:
A. Jian rounded the number of 4-ounce jars to 828 which is wrong. There are only 827 jars that can be completely filled.
B. Total number of 6-ounce jars = 551
Total money earned from 6-ounce jars = $4408
Step-by-step explanation:
A. Jian's family's collection = 3311 ounces
Number of 4-ounce jars = 
= 827.75
Jian rounded it to 828 which is wrong. There are 827 jars that can be completely filled.
Cost per 4-ounce jar = $5.
Total cost = 827 × 5 = 4135
B. Now, number of 6-ounce jars = 
= 551.83
≅ 551 jars
Cost per 6-ounce jar = $8
Total cost = 551 × 8 = 4408
1/5=x/4
0.8ft
1/5=x/6
1.2ft
Dimensions are 0.8ft X 1.2ft.
Answer:
68%
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 75, standard deviation of 4.
What percent had scores between 67 and 75?
67 = 71 - 4
75 = 71 + 4
Within 1 standard deviation of the mean, so, by the Empirical Rule, 68%.
Answer:
572$
Step-by-step explanation:
100% of 220 is 220 so add them together. Then find 60 % of 220. To find 10% of a number move the decimal to the left one time. Which is 22. After that, multiply 22 by 6 because it's 60%. then ad 220+220+132=572.
In simplifying polynomials, we need to remember
that only like terms can be added or subtracted to each other. Also, the order
of solving the basic operators should be followed which is PEMDAS.
<span>3x2y2 − 5xy2 − 3x2y2 + 2x2
The first and the thrid term is equal to zero thus the polynomial is:
</span>− 5xy2 <span>+ 2x2
</span>
The polynomial has two terms with a degree of three.
