Given the equation 10x + 20y + 40 = 0, Find it’s gradient and intercept

Mathematics

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange the given equation into this form

10x + 20y + 40 = 0 ( divide all terms by 10 to simplify )

x + 2y + 4 = 0 ( subtract x + 4 from both sides )

2y = - x - 4 ( divide all terms by 2 )

y = - \frac{1}{2} x - 2 ← in slope- intercept form

with slope m = - \frac{1}{2} and y- intercept c = - 2

What is the decimal equivalent of an 11% increase
valentinak56 [21]

Answer:

0.11

Step-by-step explanation:

You would convert the percentage to a fraction. Since the % symbol means 'out of 100', you would put 11 over 100: 11/100.

Then you would convert the fraction to a decimal: 0.11.

An easier way could also be to take the percentage and move it two decimal places to the right.

Ex: 43% moved two decimal places to the right would be 0.43.

I hope this helps!

The z-score is -1.5.

The formula to calculate a z-score is:
z=\frac{X-\mu}{\sigma}

where X is the value we're calculating the z-score for, μ is the mean and σ is the standard deviation.

Using our information we have:
z=\frac{13-16}{2}=\frac{-3}{2}=-1.5
