X = -3y+6

Mathematics

Answer:

Since x= -3y + 6

Substitute this into equation 2

You now have equation 2 as

2(-3y+6) + 8y = -12

-6y + 12 + 8y = -12

8y - 6y = -12 -12

2y = -24

y= -12

x = -3(-12) + 6

x= 36 + 6

x= 42.

Answer:

x + 3y = 6

2x + 8y = -12

substracting first equation from the second will give us

x - 5y = -18

subtracting the first one from this will give us

-8y = -24

y = 3

x = -3

Problem: The mean number of bankruptcies filed per minute in the ` States in a recent year was about two. Find the probability t
tino4ka555 [31]
The number of companies is quite large. That is, n is quite large.
The probability that a company declares bankruptcy is quite small , p is quite small.
np = the mean number of bankruptcies = 2  = a finite number.
Hence we can apply Poisson distribution for the data.
P (x=5 | mean =2) = e-2 25/5! = e-2 * 32/120 = 0.036089
Alternatively 
=poisson(5,2,0) = 0.036089
P(x≥ 5 | mean =2) = 1- P( x ≤ 4) = 1- e-2 (1+2+22/2!+23/3!+24/4!)= 1-e-2 (1+2+2+8/6+16/24)= 1-e-2(7)
  =0.052653
Alternatively
= 1- poisson(4,2,1) =0.052653
P(X > 5 | mean =2) = 1- p(x
 ≤ 5) =1- e-2 (1+2+22/2!+23/3!+24/4!+25/5!)= 1-e-2(7+4/15)
  =0.016564
alternatively=1-poisson(5,2,1)
=0.016564

This is 7th grade math..........
e-lub [12.9K]

Answer:

A

Step-by-step explanation:

Okay here's my reasoning:

they are telling us that 3 and 5 put together is 8. While this could be either A or D, this question has already told us that it equals 8. This equation is basically more better suited to 8=3+5 because this is show that 8 can be found by putting 3 and 5 together.

Hope this helps!

Q7 Find the missing angle x
Kryger [21]

Answer:

Step-by-step explanation:

Thales theorem tells us that B is a 90

and therefore from W to o (center) is 45°

we know the total of the arc VoW is 98

180= 8x +1  + 45 +98

36 = 8x

4.5 = x

x = 4.5
