A line passes through the point (1, 5) and has a slope of -9.

vladimir1956 [14]

Answer:

y= -9x+14

Step-by-step explanation:

the equation of a straight line is y=mx+c

m is the slope

And we are given a y and x term

So we substitute these into the equation:

5= -9(1) + c

rearragne to find c

14= c

so the full equation is:

y= -9x+14

A certain chalkboard manufacturer determines that their largest blackboard model has a mean length of 5.00 m and a standard devi

Igoryamba

Answer:

23 chalkboards

Step-by-step explanation:

Given:

Mean length = 5 m

Standard deviation = 0.01

Number of units ordered = 1000

Now,

The z factor = $\frac{\textup{x - Mean}}{\textup{standard deviation}}$

The z factor = $\frac{\textup{4.98 - 5}}{\textup{0.01}}$

Z = - 2

Now, the Probability P( length < 4.98 )

Also, From z table the p-value = 0.0228

therefore,

P( length < 4.98 ) = 0.0228

Hence, out of 1000 chalkboard ordered (0.0228 × 1000) = 23 chalkboard are likely to have lengths of under 4.98 m.
