Irene's mean score on 5 tests is 88%. What is
Anestetic [448]

Answer: The least score she can get on her next test is 455 points.

Step-by-step explanation: From the available information, her current mean score is 88%, and that was achieved from a total of 5 tests. Hence, her mean score was computed as follows;

Mean = (Summation of data)/observed data

Where the observed data is 5 and the mean is 88. Therefore the mean can now be expressed as,

88 = Summation of data/5

By cross multiplication we now have

88 x 5 = Summation of data

440 = Summation of data.

So, if she wants to raise her mean score on her next test to 91%, her least possible score would be derived as

91 = (Summation of data)/5

By cross multiplication we now have

91 x5 = Summation of data

455 = Summation of data

Therefore, on her next test, she must score at least 455 points.

Factorize the following:<br>5(3a + b)² +6 (3a +b) - 8​
zvonat [6]

Answer:

Step-by-step explanation:

Here, following formula will be used

(a+b)²= a²+b²+2ab

question

5(3a + b)² +6 (3a +b) - 8​

=> we will take out 3 as common number to make the term (3a+b) to fit formula requirement

=> 5x3 (a+b/3)²+6(3a+b)-8

=> 15(a²+b²/9+2xaxb/3)+18a+6b-8

here, we have expanded the formula

=> 15a²+15b²/9+15x2ab/3+18a+6b-8

=> 15a²+5b²/3+10ab+18a+6b-8
