-5^2 + (-15) ÷ (-3) + 20 Solve using PEMDAS showing work

Mathematics

oee [108]3 years ago
5 0
In PEMDAS, there is no parentheses in this equation, so we move on to exponents.

-5^2 is 25
Now, we divide -15/-3 then we get 5
Next, we do -3+20=17
25+5+17 would be 47

Your answer should be 47!
Hope this helps (:

the probability of picking rotten apple in a box is 1/100 .if there are 6 boxes containing 1200 apples each how many rotten appl
bulgar [2K]
<h3>Answer:</h3>

\huge{\boxed{72}}

<h3>Explanation:</h3>

First, find the total number of apples.  6*1200=7200

Now, multiply this by the probability of picking a rotten apple, which is \frac{1}{100}.  This is also the same as dividing by 100, or moving the decimal point two places to the left.  7200*\frac{1}{100}=72

This means that based on the probability given, 72 rotten apples will be picked.

6, 3, 4, 7, 3, 7, 8, 5, 7 i. Find the median ii. Find the mean iii. Find the modal mark
4vir4ik [10]

Answer:

i. 6

ii. 5\frac{5}{9}

iii. 7

Step-by-step explanation:

First organize the data from least to greatest.  3,3,4,5,6,7,7,7,8

To find the median, remove the extremes from the data over and over.

3,4,5,6,7,7,7

4,5,6,7,7

5,6,7

6

To find the mean, add all of the numbers and divide by 9

3+3+4+5+6+7+7+7+8=50

50/9=5\frac{5}{9}

To find the modal mark, simply find the number present most in the data set: 7(occurs 3 times)

Hope it helps <3
