Answer:
decrease
Step-by-step explanation:
Given that the sample statistics gathered would not change very much for the new sample
When it is decided to take a larger sample, we find that automatically the margin of error decreases and hence confidence interval will become narrower.
When confidence level decreases then critical value decreases and hence margin of error decreases thus resulting in to decrease the confidence level,
Hence width would decrease.
i) Because of a larger sample size
ii) BEcause of decrease in confidence level.
Y^3 * y^5 = y^8. you add the exponents
Answer:
They are -1, 4 and 7.
Step-by-step explanation:
x^3 - 10x^2 + 17x + 28 = 0
Observation of this equation shows that there is an x -intercept at x = -1 because
-1^3 - 10^(-1)^2 - 17(1) + 28 = -28 + 28
= 0.
So x + 1 must be a factor so we can do the division:
x + 1 ) x^3 - 10x^2 + 17x + 28 ( x^2 - 11x + 28
x^3 + x^2
-11x^2 + 17x
-11x^2 - 11x
28x^2 + 28
x^2 - 11x + 28 = ( x - 4)(x - 7)
x = 4, 7.
Answer:
slope = 11/2
Step-by-step explanation:
If you are given two points, you can find the slope using the point-slope equation. The equation looks like this:
y₁ - y₂ = m(x₁ - x₂)
In this form, "m" represents the slope, "x₁" and "y₁" represent the values from one point, and "x₂" and "y₂" represent the values from the other point. You can plug the values from the points into the equation and simplify to find the slope.
Point 1: (-4, 7) Point 2: (-6, -4)
x₁ = -4 x₂ = -6
y₁ = 7 y₂ = -4
y₁ - y₂ = m(x₁ - x₂) <----- Point-slope form
7 - (-4) = m(-4 - (-6)) <----- Insert values
11 = m(2) <----- Simplify
11/2 = m <----- Divide both sides by 2
