Hey! can someone give me the y=mx + b for:

guajiro [1.7K]

y=-2x+14

Step-by-step explanation:

use point slope

y-y1=m(x-x1)

and m= y2-y1

x2-x1

m= 4-2

5-6

m=2/-1

then use the 1st formula to plug everything in

y-2=-2(x-6)

then distribute the 2 on the right side

y-2=-2x-2×-6

-2×-6 is 12 since a negative times a negative is positive

y-2=-2x+12

then to get y alone we have to get everything on the right side of the = sign, so the opposite of subtraction is addition, lets add 2 to the right

y-2=-2x+12

+2. +2

y=-2x+14

The diameter of a spindle in a small motor is supposed to be 4.1 millimeters (mm) with a standard deviation of 0.1 mm. If the sp

adoni [48]

Answer:

The null hypothesis is $H_0: \mu = 4.1$

The alternate hypothesis is $H_a: \mu \neq 4.1$

Step-by-step explanation:

The diameter of a spindle in a small motor is supposed to be 4.1 millimeters

This means that the null hypothesis is that the diameter has the supposed value, that is, $H_0: \mu = 4.1$

If the spindle is either too small or too large, the motor will not work properly. The manufacturer measures the diameter in a sample of 41 spindles to determine whether the mean diameter has moved away from the required measurement.

Tests if it has moved away, that is, if the mean is different from the specified value of 4.1. So the alternate hypothesis is $H_a: \mu \neq 4.1$
