7 0

Answer:

a_{50}=16

Step-by-step explanation:

Given that,

An airthmetic sequence,

261,256,251

We need to find the 50th term.

We have,

first term, a = 261

common difference = 256-261 = -5

The nth term of the AP is given by :

a_n=a+(n-1)d\\\\a_{50}=a+49d\\\\a_{50}=261+49(-5)\\\\a_{50}=16

So, the 50th term of the sequence is 16.

5/2.35 = x/12<br> what does x=
postnew [5]

Answer:

x = \frac{60}{2.35} or x = 25.531...

Step-by-step explanation:

<u>Step 1:  Cross Multiply</u>

<u />\frac{5}{2.35} = \frac{x}{12}

5(12) = 2.35(x)

60 = 2.35x

<u>Step 2:  Divide both sides by 2.35</u>

<u />60 / 2.35 = 2.35x / 2.35

x = \frac{60}{2.35} or x = 25.531...

Answer:  x = \frac{60}{2.35} or x = 25.531...

Write 0.624 as a percent and as a simplified fraction.
Doss [256]
Okay to find the percent version of 0.624 you multiply by 100. 0.624×100=62.4%. Now as a fraction the last number behind the decimal is in the thousandths place so put 624 over 1000. 624/1000 simplified it would be 78/125

Erin has 5 cans of juice and drinks 1/3 of a can daily. in how many days will she empty all the cans she has? I think it's 1/15
In-s [12.5K]
The correct answer to your question is 15 days because if she drinks 1/3 of a can a day it will take 3 days to drink one can. Now multiple the 3 days for one can by the 5 cans and you get 15 days to finish all of the cans.

If each value of the data of the poplation function is doubled which of the following is not correct?
Anna35 [415]

Answer:

The variance is doubled; C

Step-by-step explanation:

Here, we want to select what will be wrong if every number in the dataset is doubled

A. This is correct

The mean is the average of the numbers which is calculated by dividing the sum of the numbers by the count of the numbers

By doubling the numbers, we have simply doubled the sum while the count is same

So what we have as the result of the division will be 2 times what we had initially making the mean doubled

B. The mode is doubled

Yes, this is correct

The mode is the highest in frequency

Doubling all numbers will not double their frequencies but their values. So the number that was the mode in the previous case will be the same but now doubled

D. The median is doubled

This is correct

The median deals with the middle number.

Since all numbers are doubled in the present case, the median to is also doubled along side as the numbers are now twice what they were evenly

C. This is wrong

The variance has to do with the spread of data

We are actually subtracting values

Since we are doubling across board, the difference between the numbers is the same as this, the variance cannot change

We can look at this from the angle that all others are measures of central tendency looking at having a central figure while the variance is a measure of spread.
