Answer:

X ≥ 112,6 $

Step-by-step explanation:

Normal Distribution N ( 95 , 16 )

μ₀ = 95

σ = 16

We need to get z (score) for area 0,1357; then from z - Table we get

z (score) = 1,1

Now z (score ) = ( X - μ₀ )/σ

1,1 = ( X - 95 ) / 16

17,60 + 95 = X

X = 112,6 $

That means that in order to get a gift customes has to spend at least 112,6 $

If x-9 is a factor of x-5x-36 what is the other factor

dimaraw [331]

The other factor would be (x + 4). We can find this by using synthetic division. To do this, we must first find the divisor, which would be 9, if we let x - 9 equal to zero and solve for x. Then, for the dividend, we can use the coefficients and constant term values.
<u>9</u>| 1 -5 -36
<u> 9 36</u>
1 4 0
Therefore, the other expression (x + 9) would be (x + 4). Hope this helped!

Answer:

y=3x+19.

Step-by-step explanation:

1) according to the condition the line 't' is parallel to the line 's', it means, the equation of the line 't' is: y=3x+C, where C - unknown number.

2) in order to calculate the 'C', it need to substitute the given coordinates into the equation of the line 't', then:

-2=3*(-7)+C, ⇒ C=19.

3) if C=19 and the equation of the line 't' was y=3x+C, then it is possible to make up the full required equation:

y=3x+19.
