Is 5/8 a rational number?

2 answers:

7 0

5/8 is a rational number because 5/8 as a percentage is 62.5. As long as the number doesn't go on forever without any patterns, it will be a rational number. If it does go on forever and doesn't have a pattern then it is an irrational number.

Yes !!
rational numbers are those which can be written in the form of p/q , where q is not equal to 0 ....and p and q are real integers ...
so 5/8 is a rational number ...

Hope it helps !!!

Tresset [83]

Given:

$\to \bold{52,998 \times 67 = (1,000 - 998) \times 67}$

To find:

Proving

Solution:

$\to \bold{52,998 \times 67 = (1,000 - 998) \times 67}$

Solving L.H.S part:

$\to \bold{52,998 \times 67}\\\\\to \bold{3,550,866}\\\\$

Solving R.H.S part:

$\to \bold{(1,000 -998) \times 67}\\\\\to \bold{(2) \times 67}\\\\\to \bold{ 134 }\\\\$

Therefore $\bold{L.H.S \bold{\neq} R.H.S}$

The probability that a student pilot passes the written test for a private pilot's license is 0.7. what is the probability that

zhenek [66]

<span>Probability = 0.063 Fourth try = 0.0973 Let X be the number of failed attempts at passing the test before the student passes. This is a negative binomial or geometric variable with x â {0, 1, 2, 3, . . .}, p = P(success) = 0.7 and the number of successes to to observe r = 1. Thus the pmf is nb(x; 1, p) = (1 â’ p) xp. The probability P that the student passes on the third try means that there were x = 2 failed attempts or P = nb(2, ; 1, .7) = (.3)2 (.7) = 0.063 . The probability that the student passes before the third try is that there were two or fewer failed attmpts, so P = P(X â‰¤ 2) = nb(0, ; 1, .7) + nb(1, ; 1, .7) + nb(2, ; 1, .7) = (.3)0 (.7) + (.3)1 (.7) + (.3)2 (.7) = 0.973 .</span>

Sean and Evan are college roommates who have part-time jobs as servers in restaurants. The distribution of Sean’s weekly income

Sauron [17]

Answer:

d. 0.303

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.

Subtraction between normal variables:

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

In this question:

We want the probability of Sean having a greater income than Evan, which is the probability of the subtraction of Sean's income by Evan's income is greater than 0.

Distribution of the difference between Sean's and Evan's income:

Sean has mean 225, Evan 240. So

$\mu = 225 - 240 = -15$
