Answer:

Option A and Option C

Step-by-step explanation:

Option A: 32y^{10}-24 = 8(4y^{10}-3) This is completely factored as 8 is the Highest Common Monomial factor

Option B: 18y^{3}-6y = 3y(6y^{2}-2) This is not completely factored as 2 is still a common factor of 6y2 and -2.

Option C: 16y^{5}+12y^{3}=4y^{3}(4y^{2}+3) This is completely factored as 4y2 is the Highest Common Monomial factor

Option D: 20y^{7}+10y^{2} = 5y(4y^{6}+2y) This is not completely factored as 2y is still a common factor of 4y6 and 2y.

So the options that are completely factored are Option A and Option C

The weight of items produced by a machine is normally distributed with a mean of 8 ounces and a standard deviation of 2 ounces.
Wittaler [7]

<span>First we calculate z using the formula:

z = (x - μ)/σ</span>

Where:

x = our variable, 10

μ = mean, 8

σ = standard dev, 2

Substituting known values:<span>
z = (10 - 8)/2
z = 2/2
z = 1

Using the tables of the normal distribution to find the p-value with z = 1

p = 0.8413

Since we want "greater than 10”, we need to subtract the probability from 1 therefore

p* = 1 - 0.8413 = <span>0.1587</span></span>

seropon [69]

Answer: Interval

Step-by-step explanation:

When there is a fixed unit of measure that means arithmetic operations like addition and subtraction can be done on it. So it is interval scale of measurement.

Evaluate: 8 - 9+(-2)
Kobotan [32]
Evaluate : 8 - 9 + (-2)



8-9= -1 (because if you take away 9 from 8, you will end up with a negative number since there isn’t enough to take away.)

-1 + -2 = -3 (this is because when you are adding two negative numbers together, you will basically just add -1 and -2 as you would normally, then you would transfer the negative sign as well to make it -3)

Finally, your answer to this question is -3.

Write the following equation in slope-intercept form. . . 3x - 2y = 5 . . . . y = -3/2 x - 5/2 . y = 3/2 x - 5/2. y = -3/2x + 5/
SVEN [57.7K]
Writing any equation in slope-intercept form means keeping the "y" along in one side of the equation. The equation given in the question is 
3x - 2y = 5
Subtracting 3x from both sides of the equation, we get
- 2y = 5 - 3x
Now, dividing both sides by - 2 we get
y = (-5/2) + (3/2)x
   = 3/2 x - 5/2
The correct option is the second option that is given in the question.
