Answer:

The graph of a linear equation can either run uphill or downhill. The slope is positive when the line is uphill, while the downhill line represents a negative slope. To find the slope, find two coordinates along the line.

Solve for x<br> 1/4x^3 = -27/5

Licemer1 [7]

Answer:

x = ∛(-21/6)

Step-by-step explanation:

Multiply both sides by 20 to remove the fractional coefficients:

5x^3 = -108

Divide both sides by 5:

x^3 = -21/6

Then x = ∛(-21/6)

A set of data has a normal distribution with a mean of 50and a standard deviation of 8. What percent of the data should be less

meriva

50% of data will be less than 50

Step-by-step explanation:

A normal distribution has the shape of the graph like a bell.

Given

$Mean=50\\SD = 8$

we have to find how much data will be less than 50.

So we have to calculate z-score for 50.

$z-score=\frac{x-Mean}{SD}\\=\frac{50-50}{8}=0$

The z-score is zero. As we have to find the number of values less than 50 we will find the area to the left of curve

$P(z$

In order to convert the probability into percentage

=0.50*100

=50%

Hence,

50% of data will be less than 50

Keywords: Probability, Area under the curve

Pablo bought a new laptop for $864. He is paying it off over

maks197457 [2]

Answer:

$72

Step-by-step explanation:

He bought the computer for $864 & will be paying it off over 12 months. So to get the cost per month you divide 12 from 864 and get 72. So your equation is 864/12 which gives you an answer of 72.
