Answer:(6,-2)

Step-by-step explanation:

M is the midpoint of AB then ,

M = \frac{A+B}{2}

5=\frac{x+4}{2}     ,     -2=\frac{y-2}{2}

10=x+4  ,      -4=y-2

x=6          ,      y= -2

so, B= (6,-2)

A pole, 90 cm long, is painted green, white, and black in the ration 3:4:2. What length of the pole is painted black?
ollegr [7]
3u + 4u + 2u = 9u
9u = 90
1u = 90/9 = 10

since black is 2u ( from the ratio given)
2u = 10 x 2 = 20

Answer : 20cm of the pole is painted black.

A concession stand vendor counts the money in the register. after 2 h it has $82.75. after 6 h is has $ 360.75. how much money w
Volgvan
I believe the answer would be c. $499.75. If you take (360.75-82.75)/(6-2) you get 278/4 which is dollars/hour, and that =69.5 so the rate of increase is $69.50 per hour, therefore if 6 hours produced $360.75 then you +$69.50•2(hours) and get $499.75

We will be comparing empirical probabilities (relative frequencies based on an observation of a real-life process) to theoretica
Iteru [2.4K]

Answer:

The discrete probability distribution satisfies all the features,

Step-by-step explanation:

We are given the following discrete probability distribution:

Outcome:         0           1                2            3            4            5            6

Probability: 0.0570   0.2281   0.3462   0.2547   0.0955   0.0173   0.0012

Property of discrete probability distribution:

0

\Displaystyle\sum P(x_i) = 1

Verification:

1. As observed all the probabilities are between 0 and 1.

2.

\displaystyle\sum P(x_i) =\\\\=0.0570+0.2281+0.3462+0.2547 + 0.0955 +0.0173 +0.0012 = 1

Thus, the given discrete probability distribution is a valid distribution.
