The US stock market collapsed in 1929.

The collapsing of the US stock market was a significant symptom of the US going into the Great Depression, which was a downturn in economics that lasted for 10 years. Many people were unemployed, and many of the stock market values crumbled to the ground.

Elena is trying to figure out how many movies she can download to her hard drive. The hard drive is supposed to hold 500 gigabyt

soldi70 [24.7K]

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Maximum capacity of hard drive = 500 GB

Space used up = 58 GB

Size per movie = 8GB

Number of movies = x

[(Number of movies * size per movie) + used up space] should be less than or equal to the maximum capacity to f the drive.

From Elena's inequality, the total space taken up by movies + used up space is greater than total capacity of hard drive.

That is ;

[(8x + 58 ≤ 500

8x ≤ 500 - 58

8x ≤ 442

x ≤ 442 / 8

x ≤ 55.25

The maximum number of movies Elena can download is 55

Im sruggling with this one!?

kompoz [17]

Ok, so the 4pi is indicating toward the arc length. Since the radius of the circle is 18, the circumference of the circle is 36pi. If you find the ratio of the arc length to the circumference, you can find the ratio of the indicated angle to the total number of degrees in a circle.

4pi/36pi = 1/9

(indicated angle)/360 = 1/9
(indicated angle = 40

The answer is the 4th choice, or 40 degrees.

Determine whether the value is a discrete random variable, continuous random variable, or not a random variable. a. The number

AveGali [126]

Answer:

a) it is a discrete random variable

b) It is a continuous random variable

c) It is not a random variable

d) It is a discrete random variable

e) It is a discrete random variable

f) It is a continuous random variable

Step-by-step explanation:

Explanation,

Continuous Random Variable

A continuous variable is one that can take on an uncountable set of values.

It may take any values within an interval.

It can take infinite values within an interval.

They are obtained by measuring rather than counting.

Discrete Random Variable

These can only take a discrete value and cannot be expressed in the form of decimals.

They are obtained by counting rather than measuring.

a). it is a discrete random variable ⇒ as a number of people is a discrete count, which takes values such as 0 or 1 or 2.

b). The exact time it takes to evaluate 27+72 ⇒ Since, Time is measured and thus it is a continuous random variable.

c). The gender of college students ⇒ Gender is categorical data. It is neither continuous nor discrete.

d). The number of hits to a website in a day ⇒ Since the number of people cannot be expressed as decimals, thus it is a discrete random variable

e). The number of bald eagles in a country ⇒ Since the number of people cannot be expressed as decimals, thus it is a discrete random variable

f). The distance a baseball travels in the air after being hit ⇒ Distance is measured and thus it is a continuous random variable.

Hey can you please help me posted picture of question :)

lyudmila [28]

Answer:
The roots are: √11 + 2 and -√11 + 2

Explanation:
First, we would put the equation in the standard form which is as follows:
ax² + bx + c = 0

This can be done as follows:
x² - 4x + 4 - 11 = 0
x² - 4x - 7 = 0

By comparison:
a = 1
b = -4
c = -7

Now, to get the roots, we would use the quadratic equation shown in the attached image.

By substitution, we would find that:
either x = √11 + 2
or x = -√11 + 2

Hope this helps :)
