Total number of snacks = 60
Total earnings = $220
Assumed all that are sold are small snacks = 60 x 3 = $180
The difference in earnings = 220 - 180 = $40
The difference in snack price = $5 - $3 = $2
Number of Large snacks = $40 ÷ 2 = 20
Number of small snacks = 60 - 20 = 40
Answer: 20 large snacks and 40 small snacks
Answer:

Big prism=19*12*6=1368ft³
Total=360ft³+1368ft³=1728ft³
Answer: The length of approximately 68% of all pig pregnancies will fall between <u>109 days</u> and <u>119 days</u>.
Step-by-step explanation:
According to the empirical rule , 68% of the population falls within one standard deviations from the mean.
Given : For pigs, the length of pregnancies varies according to a normal distribution with a mean of 114 days and a standard deviation of 5 days.
According to the Empirical Rule, the length of approximately 68% of all pig pregnancies will fall between
days and
days .
i.e. the length of approximately 68% of all pig pregnancies will fall between <u>109 days</u> and <u>119 days</u>.
Answer:
subtract the bigger number for smaller
Step-by-step explanation:
(a) y >_ 13
(b) x > 17.5
Explanations:
(a)
24.2 - y <_ 11.2
- y <_ 11.2 - 24.2
-y <_ -13
y >_ 13
(b)
- 12.5 + x > 5
x > 5 + 12.5
x > 17.5
(<_ means “less than or equal to” and >_ means “greater than or equal to”)
