Dylan delivers parcels.
vovikov84 [41]

Answer:

Dylan delivered 140 parcels on Wednesday.

Step-by-step explanation:

On Wednesday:

On Wednesday, he delivered x parcels.

Thursday:

10% more than Wednesday, so 100 + 10 = 110% of x = 1.1x

Friday:

50% pless than on Thursday, so 100 - 50 = 50% of 1.1x = 0.5*1.1*x.

THis is equals to 77. So

0.5*1.1x = 77

x = \frac{77}{0.5*1.1}

x = 140

Dylan delivered 140 parcels on Wednesday.

What is the value of y?
shepuryov [24]
<h3>Answer:   y = 3</h3>

===========================================================

This is because quadrilateral JMQP is also a parallelogram. Note the arrow markers to tell us that JM is parallel to PQ, and also JP is paralle to QM.

A parallelogram has its opposite sides parallel, and those opposite sides are the same length.

JM = PQ and JP = QM

Because y = QM, QM = JP, and JP = 3, this means y = 3.

Three shoppers from the survey are selected at random, one at a time without replacement. What is the probability that none of t
Travka [436]

Answer:

0.395

Step-by-step explanation:

The computation of the probability that none of the three shoppers purchased electronics is shown below:

So, first we have to determine the number of shoppers without considering the purchase i.e

= Total number of shoppers - electronics

where,

Total number of shoppers = Offices supplies + electronics + clothing + beauty supplies - electronics

= 18 + 25 + 40 + 12 - 25

= 95 - 25

= 70

Now the probability is

= \frac{70}{95}\times\frac{69}{94}\times\frac{68}{93}

= 0.395
