Answer:
0.9153
Step-by-step explanation:
Computing the z-statistics
Now we must compute the area under the Normal Curve with mean 0 and standard deviation 1 between -1.5 and 2.1
P(-1.5 < x < 2.1) = 0.9153
To compute this value we could use a calculator or a spreadsheet.
<em>In Excel or OpenOffice Calc use
</em>
<em>NORMSDIST(2.1) - NORMSDIST(-1.5)
</em>

The average is 0.9
-2.5 + 5.2 + 1.7 + (-0.8) = 3.6
3.6 / 4 = 0.9
Answer:
a = 0.3 and b = - 1.1
Step-by-step explanation:
(x - 2)² = x² -4x + 4
Hence, x² - 4x + 4 = 3x - 6
x² - 7x + 10 = 0
(x - 5)(x - 2) = 0
∴ x = 5 or 2
f(5) = 25a + 5b = 2 ----- (i)
f(2) = 4a + 2b = -1 ------ (ii)
(i) X 2: 50a + 10b = 4 ----- (iii)
(ii) X 5: 20a + 10a = -5 ---- (iv)
Subtract (iv) from (iii): 30a = 9
a = 0.3
Substitute a into (ii) to obtain b
4(0.3) + 2b = -1
2b = -1 - 1.2 = -2.2
∴ b = -1.1
