Evaluate the expression. [(8 x 7) – 2): 9​

Mathematics
1 answer:
frozen [14]2 years ago
6 0

Answer:

☑ Answer is 6

Step-by-step explanation:

{ \tt{ \{(8 \times 7) - 2 \} : 9}} \\  = { \tt{(56 - 2) :9 }} \\  = { \tt{54 :9 }}

» But this is a ratio, so it can be expressed in terms of fractions:

= { \tt{ \frac{54}{9} }} \\

» Divide both the denominator and numerator by 9:

{ \tt{ =  \frac{54 \div 9}{9 \div 9} }} \\  \\  = { \tt{ \frac{6}{1} }} \\  \\  = 6

Ganezh [65]

Answer : option A

To find the range of scores that represents the middle 50 % of the student who took the test , we find inter quartile

Inter quartile range is the middle 50% of the given range of scores.

The difference between the upper quartile and lower quartile is the inter quartile that is middle 50%

From the diagram , we can see that

Upper quartile = 89

lower quartile = 65

So range is 65%  to 89%

Here, Alicia is wrong because on evaluating 3 ^{1.4} we get 4.65554 which is of course less than 6. Zara's calculation could be;

3 ^{1.4}  \\  \\ 3 ^{ \frac{7}{5} }  \\  \\  \sqrt[5]{3 ^{7} }   \\  \\ 3 \sqrt[5]{3 ^{2} }  \\  \\ 3 \sqrt[5]{9}  \\  \\  = 4.6554
