X squared+y=18
x+y=6. use elimination method.(+y and +y cancels
x squared -x=x
18-6=12
x=12
for y take one of the above equations
x+y=6(replace x with 12
12+y=6(collect the like terms
y=6-12
y=-6

so x=12 and y=-6

mihalych1998 [28]

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 = $\frac{18}{20} =0.90$

b. Find the probability that neither of the mangoes is damaged. =

Prob of selecting 2 from 18 good mangoes

= $\frac{18C2}{20C2} =0.5276$

c. Find the probability that both mangoes are damaged.

= Prob of selecting 2 from 2 bad mangoes

= $\frac{2C2}{20C2} =0.005263$
