The y-intercept would be 2. This is due to the fact that when the line cross through the y axis, it is 2.

Solve the equation for y: -2y=-x+7

vitfil [10]

To solve for a variable means to ISOLATE the variable on one side of the equation. To do so, divide both sides by the coefficient of y.

Look:

2y/2 = (-x+7)/2

Answer: y = (-x + 7)/2

The answer can also be written as

y = -(x/2) + (7/2)

Both answers mean the same thing.

erastovalidia [21]

Answer:

x=0 or x=−5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x^2+15x=0

Step 2: Factor left side of equation.

3x(x+5)=0

Step 3: Set factors equal to 0.

3x=0 or x+5=0

x=0 or x=−5

The number of blueberries in a blueberry muffin baked by EarthHarvest Bakeries can range from 20 to 40 blueberries. (a) Use the

taurus [48]

Answer:

a) Standard deviation: 3 bluberries

b) We assume, to apply this rule, that the distribution of blueberries per muffin has a bell-curve distribution, approximately normal.

Step-by-step explanation:

We know that the number of blueberries in a blueberry muffin baked by EarthHarvest Bakeries can range from 20 to 40 blueberries.

a) If we use the Empirical Rule 68-95-99.7, specifically the last term, we have that:

- 99.7% of the data will fall between 3 standard deviations from the mean.

Then, if we consider the range of 20 to 40 containing 99.7%, we can calculate the standard deviation as:

$UL-LL=2*(3\sigma)\\\\40-20=6\sigma\\\\ \sigma=20/6=3.33\approx 3$
