X^3 / X^5 = X^ -2

you have to subtract the exponents when you’re dividing

32.323232 as a fraction in simplest form

Step2247 [10]

Let x = 32.323232…

Then 100x = 3232.323232…

It follows that

100x - x = 3232.323232… - 32.323232…

99x = 3200

x = 3200/99

. When the last 3 digits of a year (such as

Nataliya [291]

Answer:

A ; 23rd century

Step-by-step explanation:

Here, we want to select which of the options is next to have a descending year.

Since all are in the same century i.e 20-something, we do not have an issue with the first digit.

What we need to work on is the last three digits;

We can have 2210, we can have 2321, we can have 2432, we can also have 2543 and so on.

The most recent of all these is the year 2210, so what century does this belong?

Kindly note that, the years 2001-2100 belong to the 21st century.

The years 2101-2200 belong to the 22nd century while the years 2201-2300 belong to the 23rd century

The year we are looking to place is the year 2201 and thus belongs to between 2201-2300 which is the 23rd century

Assume that the random variable X is normally distributed, with mean ? = 50 and standard deviation ? = 7. Compute the following

sineoko [7]

Answer:

Step-by-step explanation:

Given that the random variable X is normally distributed, with

mean = 50 and standard deviation = 7.

Then we have z= $\frac{x-50}{7} is N(0,1)$

Using this and normal table we find that

a) $P(56$

b) When z=0.02

we get

$x=50+0.02(7)=50.14$

c) 90th percentile z value =1.645

90th percentile of X $=50+7(1.645)\\= 50+11.515\\=61.515$

masha68 [24]

A is the closest I got. My answer was 32.665 using thousandth place. I found the perimeter by adding up the lengths. I found all of the lengths by using pathat oran theorem.

Find the equation of the line. Use exact numbers. y=y=y, equals x+x+x, plus

Nuetrik [128]

The equation of a line that is passing through the points (0, 4) and (1, 6) will be y = 2x + 4.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A coordinate plane. The x-axis and y-axis are each scaled by one.

A graph of a line goes through the points (0, 4) and (1, 6) will be

The equation of a line that is passing through the points (0, 4) and (1, 6) will be

y - 4 = [6 - 4 / 1 - 0] (x - 0)

y - 4 = 2x

y = 2x + 4

The graph is given below.

More about the linear system link is given below.
