Answer:
31.
Step-by-step explanation:
-93x+3y=108
Convert to slope-intercept form ( y = mx + c where m = slope):-
3y = 93x + 108
Divide through by 3:
y = 31x + 36 <------- Slope/intercept form.
So the slope = 31.
Answer:
19/3 or 6.33 continuing
Step-by-step explanation:
using pemdas, do the exponent first
6-2=4
then multiply by 4
4x4 is 16
add 3^2 to this, which = 9
so 16+9-6 is on top which equals 19, this is over 3
so 19/3
Answer:
a) 0.383
b) 0.375
Step-by-step explanation:
a) Calculate each z-score.
z = (x − μ) / σ
z₁ = (112 − 118) / 12 = -0.5
z₂ = (124 − 118) / 12 = 0.5
Use a calculator or z-score table to find the probability.
P(-0.5 < Z < 0.5) = 0.6915 − 0.3085 = 0.383
b) 0.383 × 16 ≈ 6. So the expected proportion would be 6/16 = 0.375.
