Plz help me ;-; <br> what is 3.41 repeating as a fraction

Sholpan [36]

Remark

I'm going to assume that it is just the 0.41 that is doing the repeating. If it is not leave me a note.

Solution

The trick is to call x = 3.4141414141 ....

then multiply by 100

100 x = 341.4141414141 ............ Now write the original decimal underneath.

<u>. . . x = 3.414141414141 ......</u>...... Subtract

99 x = 338 That's all that's left. The decimal part cancels out.

x = 338 / 99 Fractional answer.

x = 3 39/99

x = 3 13/33 If this isn't one of your answers, leave me a note.

nexus9112 [7]

Answer:

C. $\frac{9}{14}$ , 9:14 , or 9 to 14

Step-by-step explanation:

With there being 9 teachers and 5 aides, the total number of adults is 14, leaving a fraction of $\frac{9}{14}$ , 9 teachers and 14 adults. Checking to simplify, there are no shared values by 9 and 14, so it is in it's simplest form.

The ages of trees in a forest are normally distributed with a mean of 25 years and a standard deviation of 4. Approximately what

harkovskaia [24]

Answer:

78.88%

Step-by-step explanation:

We have been given that

$\mu=25,\sigma=4,x_1=20,x_2=30$

The z-score formula is given by

$z-\text{score}=\frac{x-\mu}{\sigma}$

For $x_1=20$

$z_1=\frac{20-25}{4}\\\\z_1=-1.25$

For $x_2=30$

$z_2=\frac{30-25}{4}\\\\z_2=1.25$

Now, we find the corresponding probability from the standard z score table.

For the z score -1.25, we have the probability 0.1056

For the z score 1.25, we have the probability 0.8944

Therefore, the percent of the trees that are between 20 and 30 years old is given by

0.8944 - 0.1056

= 0.7888

=78.88%
