The equation
Reptile [31]

Answer:Parallel to y-6x=1 and passing through the point (3,-11) thank you ... solve the first equation for y, you will have slope-intercept form (y=6x+1). That means the slope of the given line is 6. Parallel lines have the same slope. Use point-slope form to write the equation of the parallel line. ... solve a/a+5=3/a+1

Step-by-step explanation: ... Hoped i helped :) !

Simplify the expression the best you can:<br> (9x−4)−(2x−7) =
Kobotan [32]

Answer:

7x+3

Step-by-step explanation:

To simpfly, it would help by simply ignoring the variable (x) and just looking at the number before it, solving it like a regular math problem, from left to right.

9(x) - 2(x) = 7(x)

(-4)-(-7) = 3 --> since there's a minus sign in the middle subtracting the two numbers and one on the -7, the -7 becomes a positive 7. A negative times a negative is always positive so, it would technically be -4+7=3.

Put both of these two numbers together and you get your answer,

7x+3.

If you're having trouble with the part I explained the image might help. Read it from left to right. A negative # + a negative # = positive #, as seen by the first row.

Suppose a normal distribution has a mean of 266 and a standard deviation of
Jet001 [13]

Answer:

P(x>278) is 0.16

Step-by-step explanation:

We are given that a normal distribution has a mean of 266 and a standard deviation of  12.

Mean = \mu =266

Standard deviation =\sigma = 12

We are supposed to find P(x > 278)

So, Formula : Z=\frac{x-\mu}{\sigma}

Z=\frac{278-266}{12}

Z=1

Refer the z table for p value

p value = 0.8413

P(x<278) is 0.84

P(x>278)=1-P(x<278)=1-0.84=0.16

Option A is true

Hence P(x>278) is 0.16
