Step-by-step explanation:

Important vocab:

<em><u>Irrational number:</u></em> In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers.

<u><em>Rational number:</em></u> In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.

<u><em>Integer:</em></u> An integer is colloquially defined as a number that can be written without a fractional component.

<u><em>Whole number:</em></u> Any of the numbers {0, 1, 2, 3, ...} etc.

<u><em>Real number:</em></u> Any of the numbers {0, 1, 2, 3, ...} etc.

---------------------------------

The square root of 25 is 5. From the definitions we can conclude that 5 is rational, an integer, a whole number, and a Real number.

What is -0.8 as a fraction?
stira [4]

Answer:

-\frac{4}{5}

Step-by-step explanation:

There is not much that can be done to figure out how to write 0.8 as a fraction, except to literally use what the decimal portion of your number, the .8, means.

Since there are 1 digits in 8, the very last digit is the "10th" decimal place.

So we can just say that .8 is the same as 8/10.

The fraction is not reduced to lowest terms. We can reduce this fraction to lowest  terms by dividing both the numerator and denominator by 2.

Why divide by 2? 2 is the Greatest Common Divisor (GCD)  or Greatest Common Factor (GCF) of the numbers 8 and 10.

So, this fraction reduced to lowest terms is  4/5

So your final answer is: 0.8 can be written as the fraction 8/10 simplified to 4/5

A pendulum is raised to a certain height and released from point A, as shown in the image below. At its release, the pendulum is
sweet-ann [11.9K]

The maximum height that the pendulum can reach will be 45 meters.

<h3>How to calculate the height?</h3>

It should be noted that the total energy at A should be equal to the total energy at B.

Therefore, this will be calculated thus:

1/2(14)² + 10(35) = 1/2(0)² + mgH

98 + 350 = 10H

448 = 10H

H = 448/10

H = 44.8 meters

H = 45 meters approximately

At a certain hospital, the probability of a child being born female is 0.51. If 80 babies are born on the a certain day, the pro
Ber [7]

Answer :

0.53

Step-by-step explanation:

Given the following :

Probability of female = probability of success on a single trial = 0.51

Number of babies = 80

Probability that more than half of the babies are female : p(X >80/2) = P(X > 40)

The problem can be solved using the binomial probability function :

P(X > 40) = [ p(X= 41) + p(X= 42) +.... +p(X= 80)]

In other to save computation time, we can use the binomial probability calculator

Hence ; P(X > 40) = 0.527 = 0.53
