So lets do it like this:
z = (X-Mean)/SD
<span>z1 = (8-12)/2 = - 2 </span>
<span>z2 = (16-12)/2 = + 2 </span>
<span>According to the Empirical Rule 68-95-99.7 </span>
<span>Mean more or less 2SD covers 95% of the values </span>
So t<span>he percentage of data points falling between 8 and 16 = 95%
</span>I hope this can help
Answer: a = 1 b = 7
Step-by-step explanation:
x^2(y^3)^4/x.y^5 = x^a.y^b
x^2(y^12) = x^a.y^b
(x^2).(y^12)/x^y^5 = x.y^7
x.y^7= x^a . y^b -> <u>x^1.y^7</u>
Answer:
the Swiss Chalet had higher occupancy than its competitive set in 2019
Step-by-step explanation:
You can break the equation into two groups:
6a² + 5a - 6
(9a - 6) + (6a² - 4a)
Simplify:
(9a - 6)
3(9a - 6)
(3a - 2)
--------------------------
(6a² - 4a)
2a(6a² - 4a)
(3a - 2)
--------------------------
(3a - 2)(2a+3)
You can't simplify any further, so that will be your answer.
Answer:
(2a + 3)(3a - 2)
