Answer:
p = 0.0116
Step-by-step explanation:
We are given;
Population mean; μ = 200 mg
Sample mean; x¯ = 194.3 mg
Standard deviation; σ = 21 mg
Sample size; n = 70
Formula for z-score is;
z = (x¯ - μ)/(σ/(√n))
z = (194.3 - 200)/(21/√70)
z = -5.7/2.51
z = -2.27
From the z-score table attached, the p-value at z = -2.27 is p = 0.0116
4.4 inches because once you add 2 and 2 you 50 then add ten and you get 60
Answer:
y = 2/5x - 3
Step-by-step explanation:
Rearrange the equation to get y by itself.
5y = 2x + 5
y = 2/5x + 1
Using y = mx + b and knowing that parallel lines have the same slope plug in the coordinate points given.
-1 = 2/5(5) + b
-1 = 2 + b
b = -3
y = 2/5x - 3
Answer:
Parrot fish = 56
Tigerfish = 224
Step-by-step explanation:
4p + p = 280
5p = 280
p = 56
t = 4 (56) = 224
