Which number produces an irrational number when added to 0.4

erastovalidia [21]

Answer:

0.31311311131111....

Step-by-step explanation:

We need to tell a number which when adds to 0.4 makes it a Irrational Number . We know that ,

<u>Rational</u><u> number</u><u> </u><u>:</u><u>-</u> The number in the form of p/q where p and q are integers and q is not equal to zero is called a Rational number .

<u>Irrational</u><u> number</u><u> </u><u>:</u><u>-</u> Non terminating and non repeating decimals are called irrational number .

Recall the property that :-

<u>Property</u><u> </u><u>:</u><u>-</u><u> </u> Sum of a Rational Number and a Irrational number is Irrational .

So basically here we can add any Irrational number to 0.4 to make it Irrational . One Irrational number is ,

$\rm\implies Irrational\ Number = 0.31311311131111...$

So when we add this to 0.4 , the result will be Irrational . That is ,

$\rm\implies 0.4 + 0.31311311131111 ... = 0.731311311131111 ..$

A new car that is a gas- and electric-powered hybrid has recently hit the market. The distance travelled on 1 gallon of fuel is

Darya [45]

Answer:

15.87% probability that the car travels more than 53 miles per gallon.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 45, \sigma = 8$

Find the probability of the following events: A. The car travels more than 53 miles per gallon. Probability

This is the pvalue of Z when X = 53. So

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

$Z = \frac{53 - 45}{8}$

$Z = 1$

$Z = 1$ has a pvalue of 0.8413

1 - 0.8413 = 0.1587

15.87% probability that the car travels more than 53 miles per gallon.

Pedro deposited $35 then withdrew $50 show number line graph

VARVARA [1.3K]

If you <em>deposit</em> $35, you can imagine drawing a green line (representing the money gained) to the 35 on the number line, which can be seen as <em>moving </em>35 to the right<em />. Fo <em>w</em><em>ithdrawing, </em>imagine drawing a red line back 50 notches on the number line (representing money lost). The net effect that the deposit and withdrawal will have on your account balance is a $35-50=-15$ dollar <em>loss</em>, which can be represented on the number line as a line drawn to the point -15.
