Answer:
x = 8.8 or x = 44/5
Step-by-step explanation:
1) Multiply both sides of the equation by 4, and cancel out the 4 on the bottom of 3/4, this turns the equation into: 8x - 4 = 3x + 40
2) Move the x to the lefthand side and change the side, do the same for the constant (4), this turns the equation into: 8x - 3x = 40 + 4
3) Combine like terms, subtract 8x from 3x and add 40 to 4: 5x = 44
4) Divide both sides by 5, and your answer is 44/5 (or 8.8 when converted to a decimal)
Answer:
I'm adding weight recently
Answer: (0.465, 5.535)
Step-by-step explanation:
Formula to calculate the confidence interval (<em>when population standard deviation is unknown</em>) is given by :-
, where = sample mean.
s= sample standard deviation.
n= Sample size.
= critical value
By considering the given information , we have
s=0.75
n= 9
Significance level = [1-0.90=0.1]
By using students' t distribution -table , the critical value for 95% confidence level :
[Note: degree of freedom = n-1]
Now, the 90% confidence interval for the true mean weight of these Southern California avocados will be :
Hence, the required confidence interval =(0.465, 5.535)
Answer:
not a geometric series 103 can't be term of this geometric series.
From first 3 terms 90,30,10, 10/3.......................
a₁ = 90, r= 1/3
so, Sum = a₁/(1-r)
S = 90/(2/3)
S= 270/2 = 135
Note:
Your function is a little ambiguous. I think you may have tried to write your function such as:
<em>f(x) = 4x + 3</em>
I am assuming your function as:
f(x) = 4x + 3
Answer:
The value of f(3) = 15
Step-by-step explanation:
Given
Assuming the function is
f(x) = 4x + 3
To determine
The value of f(3)
The value of f(3) can be determined by substituting x = 3 in the function
f(x) = 4x + 3
substitue x = 3 in the function
f(3) = 4(3) + 3
f(3) = 12 + 3
f(3) = 15
Therefore, the value of f(3) = 15
