Find the independent and dependent variables y=x2-24x+3

Mathematics
1 answer:
Slav-nsk [51]4 years ago
4 0

Answer:

The independent variable is "x."

The dependent variable is "y."

Step-by-step explanation:

An independent variable is a variable that does not depend on an event.  It is independent of another variable.  It does not change as a result of another variable.  It remains constant as it is controlled.  It is used to measure the dependent variable.

A dependent variable varies.  It depends on the independent variable for its outcome.  It can yield various results depending on how the independent variable is changed.  "y" in our example will change its value because of the value placed on "x."  The dependent variable is the variable that is being measured or tested in an experiment.  For example, the sales revenue of goods is a dependent variable of another independent variable like price and a constant (quantity).

KATRIN_1 [288]

Answer:

The margin of error of his experiment is of 0.1074.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the z-score that has a p-value of 1 - \frac{\alpha}{2}.

The margin of error is of:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

30 M & M's from a bag, and 3 of them are green.

This means that n = 30, \pi = \frac{3}{30} = 0.1

Standard 95% confidence level

So \alpha = 0.05, z is the value of Z that has a p-value of 1 - \frac{0.05}{2} = 0.975, so Z = 1.96.

Margin of error:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

M = 1.96\sqrt{\frac{0.1*0.9}{30}}

M = 0.1074

The margin of error of his experiment is of 0.1074.

A tower casts a shadow that is 60 feet long when the angle of elevation of the sun is 65 degrees. How tall is the tower?
Margaret [11]

Answer:

128.67 feet

Step-by-step explanation:

We would be solving this question using the Trigonometric function of tan.

Tan( of the angle of elevation) = height of the tower ÷ height of the shadow.

Angle of elevation = 65°

Height of the tower = unknown, which is designated as X

Height of the shadow = 60 feet.

Therefore,

tan 65° = X/ 60 feet

We crossmultiply

X = tan 65° × 60 feet

X = 128.67041523 feet.

Approximately, X = 128.67 feet.

Therefore, the tower is 128.67 feet tall.
