Answer:
6
Step-by-step explanation:
f(x)=x^2-5x+6
To find the y intercept, set x=0
f(0) = 0^2 -5(0) +6
f(0) = 6
The y intercept =6
Answer:
0.6836
Step-by-step explanation:
(weight - mean weight) = 48
Variance, s² = 204,304
Sample size, n = 89
We need to obtain the Zscore :
Zscore = (X - mean) / standard Error
Zscore = (weight - mean weight ) / (s/√n)
s = √204304 = 452
The difference from the meanncoukdnbe either to the right or left :
Zscore = - 48 / (452/√89) OR 48 / (452/√89)
Zscore = - 48 / 47.911904 OR - 48 / 47.911904
Zscore = - 1.002 or 1.002
P(Z < - 1.002) = 0.1582 (using Z table)
P(Z < 1.002) = 0.8418
P(Z < 1.002) - P(Z < - 1.002)
0.8418 - 0.1582
= 0.6836
2.86
= 28 tenths + six hundreths.
(The number directly after the decimal point is an hundreth)
Since there is a 2.0 (twenty tenths), the answer is:
20+8 = 28 tenths.
