How do I round 3.047 to the nearest hundred and show the math

1 answer:

3 0

The second place to the right after the decimal is the hundredth, so basically, to round, you cut off the rest of the decimal places afterwards. If the number after the hundredth is at or above 5, you should make the hundredth 1 higher, but if it is 4 or below, you will just leave it as is. In this case, 3.047 rounds to 3.05. There really is not any math work to show, but just the explanation.<span />

Answer:

The mean = 17.54

Step-by-step explanation:

Form a table as below;

<u>Interval Frequency{f} Midpoint of frequency{x} fx </u>

1-7 19 4 76

8-10 14 9 126

11-15 15 13 195

16-20 20 18 360

21-35 10 28 280

36-50 13 43 559

Sum 91 1596

The mean of grouped data = Sum of { Interval Midpoint * Frequency } /Sum of frequency

The mean= 1596 / 91

The mean = 17.54

Write an equivalent expression for 7¹² × 7⁴

ira [324]

Answer:

$\huge\boxed{7^{16}}$

Step-by-step explanation:

We can use exponent rules to try and simplify this expression down.

Exponent rules tell us that $x^a + x^b = x^{a+b}$ .

This means that since we have the same base on both terms (7 and 7), we can add the exponents to get a simplified expression.

$12 + 4 = 16$

So our simplified expression is $7^{16}$ .

Hope this helped!
