A confidence interval is the mean of the estimate plus and minus the variation in that estimate.

From the excel, Confidence.T(0.10,1.45,15)

Margin of error = 0.659414066

Lower limit will be;

= mean-0.659414066

= 5.3 - 0.659414066

= 4.640585934

Upper limit will be:

= mean+0.659414066

= 5.3+0.659414066

= 5.959414066

Answer:

x= 2, y= -3

Step-by-step explanation:

Given two equations, we can solve them by either substitution or elimination method. Let's solve by substitution!

x -y= 5

Rewrite this equation such that one of the variable is the subject of formula, so that we can substitute this equation into the second.

x= y +5 -----(1)

3x +y= 3 -----(2)

Substitute (1) into (2):

3(y +5) +y= 3

Expand:

3y +15 +y= 3

4y= 3 -15

4y= -12

y= -12 ÷4

y= -3

Substitute y= -3 into (1):

x= -3 +5

x= 2

The -5⁻³ matches with -1/125, (-5⁻³)⁻¹ matches with -125, and (-5⁻³)⁰ matches with 1.

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

5⁻³ = 1/5³ = 1/125

-5⁻³ = -1/5³ = -1/125

(-5⁻³)⁻¹ = (-1/5³)⁻¹ = (-1/125)⁻¹ = -125

(-5⁻³)⁰ = 1   [tex]\rm (a^0 = 1)[/tex]

Thus, the -5⁻³ matches with -1/125, (-5⁻³)⁻¹ matches with -125, and (-5⁻³)⁰ matches with 1.

The measure of the angle B is 30 degree after applying the sin law of triangle.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

We have a triangle shown in the picture:

We can apply the sin law of the triangle to find the angle B

[tex]\rm \dfrac{28}{sin91} =\dfrac{14}{sinB}[/tex]

SinB = 0.499

The linear equation that represent the pair of points (0, -1) and (4, 11) is y = 3x - 1

An equation is an expression that shows the relationship between two or more numbers and variables.

From the table, using the point (0, -1) and (4, 11), hence:

y - (-1) = [(11 - (-1))/(4 - 0)](x - 0)

y = 3x - 1

The linear function that represents the line y - 2 = 4(x - 3), in slope-intercept form, is expressed as: D. f(x)y = 4x - 10.

A linear function equation is expressed as, y = mx + b, in slope-intercept form.

Given the point-slope equation of the function, y - 2 = 4(x - 3), rewrite in slope-intercept form:

y - 2 = 4(x - 3)

y - 2 = 4x - 12

y = 4x - 12 + 2

y = 4x - 10

A strategy which would produce a new confidence interval with an increased margin of error is to: A. use a 98% confidence level.

A confidence interval simply refers to a range of estimated values which defines the probability that a population parameter will lie within it.

Mathematically, a margin of error is calculated by using this formula:

[tex]MOE_{\gamma}=Z_{\gamma} \times \sqrt{\frac{\sigma^2}{n} }[/tex]

From the above formula, we can deduce that the margin of error is directly proportional to the critical value and inversely proportional to the square root of sample size.

This ultimately implies that, increasing the confidence level from 95% to 98% would increase the critical value and by extension the margin of error and vice-versa.
