Each time 4 is being added, so do 9+4=13, then 13+4=17.

Answer:

The 5th number is 13 and the 6th number is 17.

Step-by-step explanation:

For more difficult question, you have to use this way. the rule for arithmetic sequence is An=a1+d(n-1)

So all you have to do is replace the things.

So, you are looking for the 5th spot, the first term is -3, and the difference is 4, replace the n with the 5.

A5=-3+4(5-1)

5-1 is 4

4*4 =16

A5 =-3+16

16-3=13

A5=13

Do the same for A6 , just instead of the "5's" put "6's".

A6=-3+4(6-1)

6-1 +5

5*4 =20

20-3=17

A6 =17

Answer:

0.9855 or 98.55%.

Step-by-step explanation:

The probability of each individual match being flawed is p = 0.008. The probability that a matchbox will have one or fewer matches with a flaw is the same as the probability of a matchbox having exactly one or exactly zero matches with a flaw:

P(X\leq 1)=P(X=0)+P(X=1)\\P(X\leq 1)=(1-p)^{23}+23*(1-p)^{23-1}*p\\P(X\leq 1)=(1-0.008)^{23}+23*(1-0.008)^{23-1}*0.008\\P(X\leq 1)=0.8313+0.1542\\P(X\leq 1)=0.9855

The probability  that a matchbox will have one or fewer matches with a flaw is 0.9855 or 98.55%.

Determine the standard form of the equation of the line that passes through (-2, 0) and (-8, 5).
Vladimir79 [104]

Answer:

5x + 6y = -10

Step-by-step explanation:

(-2, 0) and (-8, 5)

m = (y₂ - y₁) /  (x₂ - x₁)

m = (5 - 0) / (-8 -(-2)

m = 5 / (-8+2)

m = -5/6

y = mx + b

(-8, 5)

5 = -5/6(-8) + b

5 = 40/6 + b

b = 5 - 40/6

b = -5/3

y = mx + b

y = -5/6x - 5/3           *6

6y = -5x -5(2)

6y = -5x - 10

5x + 6y = -10
