When we carry out a Measurement of a population, we take into account different patterns when estimating both the final prediction - to which the projected survey is projected - as well as the quality of said measurement. When such measurement is made, the estimated range of data belonging to an unknown population and which in turn will be included in said measurement must be taken into account. This range is what we know as the Confidence Interval, whose value has generally been standardized at 95%.
The meaning of this Interval is no more than 95% reliability against repeated samples that could alter the final result. The value of the parameter allows you to 'immunize' against these problems. Instead of providing a timely estimate of the parameter of interest, the confidence interval provides an estimate of the parameter interval.
In the event that a specific value is sought in the result or from the sample, and we would like to obtain a range of those parameter values, it is when the Confidence Interval tool is of vital importance, as it will give the required result.
Answer:
5x^2 - 4x - 3 = 0
Step-by-step explanation:
For the equation
ax^2 + bx + c = 0
the roots are [-b +/- √(b^2 - 4ac)] / 2a
So comparing the terms to the values in the question:
a = 5
b = -4
c = -3
Answer:
1/36
Step-by-step explanation:
The probability of rolling a number less than 6 or 6 itself on one die is 1/6. A pair of dice would be the combined probability 1/6*1/6 which is 1/36. So there's a 1/36 chance of having both dice roll numbers less than 6 or 6 itself.
The equation according to the given verbal sentence is
(after solving this
).
<u>Step-by-step explanation:</u>
Rewrite the given verbal sentence and so it will be easier to translate.
Given: The quotient of the sum of 2 t and 2 and twice the cube of s
sum of 2 t and 2 can be written as
2 t + 2
twice the cube of s

Now, combine the above according to the given verbal. The quotient of the sum of 2 t and 2 and twice the cube of s means,
2 t + 2 divided by 
Now, the equation would be 
When solving this equation, we get

The ordered pair (-3 ,
) is on g(x) ⇒ 1st answer
Step-by-step explanation:
Let us revise the reflection across the axes
- If the function f(x) reflected across the x-axis, then its image is g(x) = - f(x) (change the sign of y)
- If the function f(x) reflected across the y-axis, then its image is g(x) = f(-x) (change the sign of x)
∵ 
∵ f(x) is reflected across the y-axis to create the function g(x)
- Change the sign of x
∴ 
To find the point that lies on g(x) substitute x in g(x) by the x-coordinate of the point if the answer equal to the y-coordinate of the point, then the point lies on it if not then the point does not lie on it
∵ The coordinates of the point are (-3 ,
)
∴ x = -3 and y = 
- Substitute x by -3 in g(x)
∵ 
∴ 
∴ 
∵ 
∴ 
∴ 
- Divide up and down by 2
∴ 
∵ The value of g(x) equal to the y-coordinate of the point
∴ The point (-3 ,
) lies on g(x)
The ordered pair (-3 ,
) is on g(x)
