Answer:

d = 13

Step-by-step explanation:

So first we collect like terms

-18d - (-5d) + 15d + (-15) = 11

-18 + 5d + 15d - 15 = 11

2d - 15 = 11

Add 15 to both sides

2d = 26

Divide both sides by 2

d = 13

each of the 20 balls is tossed independently and at random into one of the 5 bins. let p be the probability that some bin ends u
amm1812

if p is the probability that some bin ends up with 3 balls and q is the probability that every bin ends up with 4 balls. pq is 16.

First, let us label the bins with 1,2,3,4,5.

Applying multinomial distribution with parameters  n=20  and  p1=p2=p3=p4=p5=15  we find that probability that bin1 ends up with 3, bin2 with 5 and bin3, bin4 and bin5 with 4 balls equals:

5−2020!3!5!4!4!4!

But of course, there are more possibilities for the same division  (3,5,4,4,4)  and to get the probability that one of the bins contains 3, another 5, et cetera we must multiply with the number of quintuples that has one 3, one 5, and three 4's. This leads to the following:

p=20×5−2020!3!5!4!4!4!

In a similar way we find:

q=1×5−2020!4!4!4!4!4!

So:

pq=20×4!4!4!4!4!3!5!4!4!4!=20×45=16

thus, pq = 16.

Complete each statement from the information given and state the reasons and the triangle criterion you used.
TiliK225 [7]

Answer:

Triangle GAS = Triangle IOL by rule AAS

Step-by-step explanation:

The points must be ordered correctly so they correspond within the triangles. Point G = Point I, Point A = Point O, Point S = Point L.

A rule for determining Triangle Congruency is AAS. If two angles and a side of a triangle are equal to one of another triangle, the triangles are congruent.

Viktor [21]

Answer:

Worked 40 hrs in week

Pay $300 for week

Step-by-step explanation:

Hours: 7-11a.m = 4

12-4p.m = 4 So, 4+4=8 hrs per day

So, 8 hrs per day × 5 days a week (8×5)=40

Worked 40 hrs in week

Pay: $7.50/hr So, $7.50×40 hrs (7.50×40)=300

So, $300 pay for week
