Maths question pls answer

alukav5142 [94]

Answer:

answer should be 52.4 mins

Step-by-step explanation:

find the midpoint for each time:

1. 15mins = 7students

2. 45mins = 27 students

3. 75mins = 12 students

4. 100 = 4students

Then, do the normal mean calculation by adding up all the values and dividing it by 50.

7*15 + 27*45 + 12*75 + 100*4 = 2620

2620/50 = 52.4mins

Evaluate (−23)×(−23)3 by using the Laws of Exponents

Nikolay [14]

Given:

$\left(-\dfrac{2}{3}\right)\times \left(-\dfrac{2}{3}\right)^3$

To find:

The value of given expression by using the Laws of Exponents.

Solution:

We have,

$\left(-\dfrac{2}{3}\right)\times \left(-\dfrac{2}{3}\right)^3$

Using the Laws of Exponents, we get

$=\left(-\dfrac{2}{3}\right)^{1+3}$ $[\because a^ma^n=a^{m+n}]$

$=\left(\dfrac{-2}{3}\right)^{4}$

$=\dfrac{(-2)^4}{(3)^4}$ $[\because \left(\dfrac{a}{b}\right)^n=\dfrac{a^n}{b^n}]$

$=\dfrac{(-2)\times (-2)\times (-2)\times (-2)}{(3)\times (3)\times (3)\times (3)}$

$=\dfrac{16}{81}$

Therefore, the value of given expression is $\dfrac{16}{81}$ .
