Answer: 50% i think (probs wrong)
Step-by-step explanation:
if half the balls are even then presumably another will be
1. so just subsitute numbers if we subsitute 5 for x then we get 0 if it's height is 6 then the time will be 16
2. so you want to factor the equation and get f(x)=x^2-4x-5=(x-5)(x+1) then set this equation = to 0 so (x-5)(x+1)=0
x-5 or x+1 must equal 0 so
x-5=0
x=5
x+1=0
x=-1
discard this because you cannot yield a negative ammount
so when the bank yields 5 in a day, the income is 0
Answer:
y =65
Step-by-step explanation:
We will call the unknown angle in the triangle x
Angle x plus 130 form a straight line
x+130 = 180
Subtract 130 from each side
x+130-130 = 180-130
x = 50
The three angles in the triangle add together to make 180 degrees
x+y+y = 180
We know angle x = 50
50 + 2y = 180
Subtract 50 from each side
50+2y-50 = 180-50
2y = 130
Divide each side by 2
2y/2 = 130/2
y = 65
Answer:
The 95% confidence interval is
Step-by-step explanation:
From the question we are told that
The sample mean for fat-blocking
The sample size for fat-blocking
The standard deviation for fat-blocking is
The sample mean for control group is
The sample size for control group is
The standard deviation for control group is
Given that the confidence level is 95% then the level of significance can me mathematically evaluated as
Generally the degree of freedom is mathematically represented as
substituting values
Next we obtain the critical value of at a degree of freedom of 22 form the students t-distribution , the value is
Generally the margin of error is mathematically represented as
substituting values
the 95% confidence interval for the differences of the means is mathematically represented as
substituting values
