Answer:
A) P(x> 2575) = 14.92%
B) P(2575 < X<3300) = 14.32%
C) ( P X < 1225) = 4.55%
Step-by-step explanation:
Given data:
a) P(x> 2575)
1 - P(X<2575)
1 - P( Z< 1.04)
1 - 0.8508
0.1492
14.92%
B) P(2575 < X<3300)
P (1.04 < z< 2.51)
P(z <2.51) - P(Z<1.04)
0.994 - 0.8508 = 0.1432 = 14.32%
C) ( P X < 1225)
P ( Z< -1.69)
= 0.0455 = 4.55%
Answer:
Y=2x+7
Step-by-step explanation:
To find the gradient of the line u have to subtract the y intercepts and the x intercepts
11--9/2--8=20/10=2
Y-11/x-2=2
Y-11=2(x-2)
Y-11=2x-4
Y=2x-4+11
Y=2x+7
Answer:
24 cm
Step-by-step explanation:
The circumference would be 75.4
75.4 divided by 3.14 () is 24.0127.....
I believe this would be 24 as your answer then
(f+g)(x) is equivalent to f(x) + g(x)
So that would be (7x-3) + (x²-4x) = x² + 7x - 4x - 3 = x² + 3x - 3
Hope this helps.
