Hello,
Answer A: no solution

line 1: (-6,3), (3,6)==>y-3=(x+6)*3/9==>x-3y=-15 (1)
line 2: (-3,1), (3,3)==>y-1=(x+3)2/6==> x-3y=-6 (2)

(1)-(2)==>0x=-9 ==> no solution
line 1 // line 2

Answer:

Step-by-step explanation:

The correct explanation is A

$\frac{x^{m} }{a^{n} }$ = $a^{(m-n)}$

Thus

$\frac{9.2}{4}$ × $\frac{10^{8} }{10^{-3} }$

= 2.3 × $10^{(8-(-3))}$

= 2.3 × $10^{11}$

The amount of snow fall falling in a certain mountain range is normally distributed with a mean of 74 inches, and a standard dev

Nutka1998 [239]

Given that the sample mean is μ=74 and sample standard deviation σₓ= $\frac{σ}{ \sqrt{n}} =\frac{12}{\sqrt{36}} =2$ .

Thge Z- score is $Z=\frac{76.8-74}{2} =1.4$ .

Now we use the Z-score to calculate the required probability.

Refer to standard normal distribution table.

The required probability is

$P(X>76.8) =P(Z>1.4)=1-P(Z$
