Answer:

5.76 cm^2

Step-by-step explanation:

<em>Hey there!</em>

<em />

Well if the side length is 2.4 cm then the area would be,

A = l•l

A = 2.4 • 2.4

A = 5.76cm^2

<em>Hope this helps :)</em>

If you need $3,000 four years from now, how much would you need to deposit into an account that earns 5% interest, compounded an

Aleks04 [339]

Answer:

2468.11 dollars

Step-by-step explanation:

Amount that should be available after four years =3000 $

Interest rate = 5%

No of years =4

Let P be the principal invested

Then $3000=P(1+0.05)^4\\P=3000(1.05)^{-4} \\=2468.11$

Hence 2468.11 dollars should be deposited to get 3000 dollars after 4 years at 5% interest.

kogti [31]

Answer:

Step-by-step explanation:

<h3>Given</h3>

a4 = 13
a2 = 3
d = ?

<h3>Solution</h3>

<u>Formula for the terms of AP:</u>

a4 = a + 3d
a2 = a + d

<u>The difference of terms:</u>

a + 3d - (a - d) = 13 - 3
2d = 10
d = 5

What does the ordered pair (6, 204) represent in this situation?

maxonik [38]

An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension. The numeric values in an ordered pair can be integers or fractions.

0.0314 = 3.14% probability that it takes at most 1 hour of machining time to produce a randomly selected component

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Sum of normal variables:

When normal variables are added, the mean is the sum of the means while the standard deviation is the square root of the sum of the variances.

The mean values are 20, 15, and 30 min, respectively:

This means that $\mu = 20 + 15 + 30 = 65$
