Answer:
A. $3.63
Step-by-step explanation:
You can choose the correct answer simply by estimating.
The almonds are about $5.50 for each of the 2 kg, so will total about $11. Since the total amount paid is just over $25, the amount paid for cashews is about $25 -11 = $14.
That amount pays for 4 kg of cashews, so 1 kg will be half of half that amount, or about $3.50 -- certainly, less than $7.26.
_____
If you want to write an equation, you can write ...
2(5.49) +4(c) = 25.50
4c = 14.52 . . . . . . . . . . . . subtract 10.98
14.52/4 = c = 3.63 . . . . . divide by the coefficient of c
1 kg of cashews has a price of $3.63.
Answer:
44/100 will be reduced to 11/25
Step-by-step explanation:
Answer:
the approximate probability that the total weight of the passengers exceeds 4668 pounds is 0.0089
Step-by-step explanation:
Using the central limit Theorem
z = (x - u )/Q÷ sqrt n
Where z is the z-score
x is the average weight = 4668/22 = 212.2
u is the passengers average = 194 pounds
Q is standard deviation = 36 pounds
Therefore
z= (212.2 - 194) / 36 ÷ sqrt22
= 18.2/ 36÷ 4.69
= 18.2/7.68
z=2.3698 aprx 2.37
Find the value of 2.37 z-score on the z-table to determine the approximate probability
P(z>2.37) = 0.0089 (from the z-table)
