Answer:
180 children and 175 adults
Step-by-step explanation:
Let it be that the amount of children who visited the park that day was x, the rest was adults. It means the quantity of adults equals 355-x.
The payment from the children is 1.5*x (because each children payed 1.5 dollars, the amount of money from children is the fee from one child multiplied by the quantity of children). The money earned by the park's owners from adults are equal to the fee from one adult multiplied by the quantity 4* (355-x)= 1420 -4x
If we add the money from chilren and adults we get the summary profit of park (it is equal to 970 dollars)
1.5x+ 1420-4x= 970
1420-2.5x= 970
x=180- children
355-180=175adults
If the lines are congruent it should be 2 because 4 should be double of x
15.5 15.5 x 2 = 31. hope this helps
-1 1/8 because -9/8 is equal to
so just make it a improper fraction, pretend the negative is not there then add the negative at the end
-hope this helps :D
Answer:
Step-by-step explanation:
Given that a convenience store regularly buys mangoes from a wholesale dealer. For every shipment, the manager randomly inspects five mangoes from a box containing 20 mangoes for damages due to transportation. Suppose the chosen box contains exactly 2 damaged mangoes.
In the selected box 18 good mangoes and 2 damaged mangoes are there
a) Find the probability that the first mango is not damaged.
= prob of selecting 1 from any one of 18 good mangoes = 
b. Find the probability that neither of the mangoes is damaged.
=
Prob of selecting 2 from 18 good mangoes
=
c. Find the probability that both mangoes are damaged.
= Prob of selecting 2 from 2 bad mangoes
=
