Answer:
16.35
Step-by-step explanation:
Using an inverse normal distribution, we can calculate the z score given the percentile, which can then be used to find our value.
First, we can use an inverse normal distribution calculator to figure out that the z score given the 75th percentile is 0.674.
Next, we know that the z score is (observed value - mean) / standard deviation. We can plug our values in to get
Rounding, we get x = 16.35 as our answer
QS =25
Step-by-step explanation:
QR + RS = QS
18 + (x-11) =2x-11
7 +x =2x -11
18=x
Plug in x
2(18) -11
36-11
QS=25
18 + (18-11) = 2(18)- 11
18+ 7 = 36 -11
25= 25
True
Answer:
QS + QR > RS
QR + RS > QS
RS + QS > QR

Answer:
20, 22, 28, 50
Step-by-step explanation:
The length and width could be:
1, 1, 24, 24
2, 2, 12, 12
3, 3, 8, 8
4, 4, 6, 6
1+1+24+24= 50
2+2+12+12= 28
3+3+8+8= 22
4+4+6+6= 20
factoring:-
f = 4x^2 + 19x - 5 = (4x - 1)(x + 5)
g = 4x^2 - x = x(4x - 1)
(4x - 1) is common, so:-
f/g (x) = (x + 5) / x which is the second choice.
