She fell the appropriate number of times each day for the 5 days. She fell 9 times the first day, like the equation has in parenthesis. She did it for 5 days. 5x9 is pretty much given to you. Hope this helps. :)
is equivalent to
The given expression is :.
We collect LCM in both the numerator and the denominator to obtain:
Change to the normal division sign;
Multiply by the reciprocal of the second fraction:
Cancel out the common factors
Therefore is equivalent to
C - AC equals AD times AB over AE
C and E are correct
We have to calculate mean , median and mode for both groups first:
For the group that studied:
Mean = 92.61
Mode = 100
For the group that didn't studied:
Mean = 76
Median = 79.5
Mode = No Mode
For statement A:
the difference between means is: 92.61-76=16.61
So the statement is incorrect.
B: There is no mode of the group that studied.
This is not true as the group has a mode of 100
C.The median of the group that did not study is less than 80.
This is true as the median of the group that didn't study is 79.5.
D. The median of the group that studied is over 95
False as the median is less than 95.
E. In general, those students that studied scored much higher than those students that did not study.
As the mean of the group that studied is much more than the group that didn't study so the statement is true ..
The correct answer is first option
(7x + 4)(7x − 4)
Points to remember
(a + b)(a - b) = a² - b²
It is given an expression,
49x² - 16
To factorize the expression 49x² - 16
We know that 7² = 49 and 4² = 16
Therefore we can write the given expression as,
49x² - 16 = (7x)² - 4²
It is in the form of the above identity,
(7x)² - 4² = (7x + 4)(7x - 4)
Idk what the 6^3 x 2^6/2^3 means but 2^6 x 3^8 = 419904 and none of the other choices match this sorry.
Where's the picture?
Simplify then factor The correct answer is B.
Please provide the answer
