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

sweet-ann [11.9K]

Answer:

Yes, They are similar by SSS PMK similar to LMQ.

Step-by-step explanation:

Similar triangles corresponding side lengths are in a proportion.

KM corresponds with MQ

PM corresponds with LM.

Set up this proportion.

\frac{km}{pm}  =   \frac{lm}{mq}

\frac{15}{28}  =  \frac{21}{39.2}

Cross multiply

588 = 588

So the triangles ARE Similar.

  • PM corresponds with LM
  • KM corresponds with MQ
  • PK corresponds with LQ
  • So PMK is similar to LMQ

A positive number is 3 times another number.
Juli2301 [7.4K]

Answer:

The smaller number can be 8 or \frac{1}{5}.

Step-by-step explanation:

Consider the provided information.

let the larger number is x and the smaller number is y

A positive number is 3 times another number.

3y=x

If we add 2 to the larger and 5 to the smaller, then one of them becomes 2 times the other.

Case I: If 2nd number is 2 times to the first number.

x+2=2(y+5)

Substitute the value of x.

3y+2=2y+10

y=8

Now substitute the value of y in 3y=x

3(8)=x

x=24

Therefore, the smaller number is 8.

Case II: If 1st number is 2 times to the second number.

2(x+2)=y+5

Substitute the value of x.

2(3y+2)=y+5

6y+4=y+5

5y=1

y=\frac{1}{5}

Therefore, the smaller number is \frac{1}{5}.
