note: f=fruit
y=yoghurt
2:3
f : y
f/y=2/3
=> 3*f=2*y
f=(2*y)/3
we know that f+y=185g
(2*y)/3+y=185g
(2*y+3*y)/3=185g
5*y/3=185
y=(185*3)/5
y=111g
=>the mass of the yoghurt is 111 g
Answer:
the equation of the least-squares line for the data is: 
Step-by-step explanation:
In a simple linear regression model, such as, 
, the coefficients bo and b1 are estimated through the method of least squares by the use of the equations:
For the data provided you have to:
, thus:
the equation of the least-squares line for the data is:
Answer
The first one is equal and the second one is the first choice.
Answer:
angle 2= 52.7° (same as angle 4)
angle 1 and angle 3 = 127.3°
Answer:
0.242
Step-by-step explanation:
p = 0.08, q = 1 − p = 0.92, and n = 1000.
The mean and standard deviation are:
μ = p = 0.08
σ = √(pq/n) = 0.00858
The z score is:
z = (x − μ) / σ = -0.70
Using a calculator or z score table, the probability is:
P(Z < -0.70) = 0.242
