The margin of error is 3.38.

Option B is the correct answer.

We have,

The margin of error can be calculated using the formula:

Margin of error = z x (s/√n)

where z is the z-score corresponding to the given confidence level.

For a 95% confidence level,

z = 1.96.

Substituting the given values, we get:

Margin of error

= 1.96 x (5.9/√12)

= 3.38

(rounded to two decimal places)

Therefore,

The margin of error is 3.38.

Answer: $6.50

Step-by-step explanation:

First you do 4.55/7 and you get 0.65, then you multiply that by 10 which will get you $6.50.

it's 6.50 because when you divide 4.55/7 it's 0.65 multiplied by 10 it's 6.50

Answer:

[tex]2x^{2}[/tex]

Step-by-step explanation:

Find the GCF of the numbers 48, 6 and 26.  

The largest number each can be divided by is 2, which is the GCF.

Find the GCF of [tex]x^{2}, x^{3}, x^{6}[/tex]

The GCF is always the smallest exponent, so [tex]x^{2}[/tex] is the GCF

Combine the two GCF for the answer

Step-by-step explanation:

To obtain a solution for [tex]cos^{-1}[/tex] (x) , then

- 1 ≤ x ≤ 1

That is the value of x cannot be greater than 1 or less than - 1

here x = [tex]\frac{5}{4}[/tex] = 1.25 which is greater than 1 , thus calculator will return ' error'

Answer:

66.2 miles

Step-by-step explanation:

I used addition, since it says 40 less than Jake I added what he ran with how much less he ran.

40 + 26.2 = 66.2

The graph of the quadratic function [tex]y=ax^2+bx+c[/tex]

does not intersect the x-axis, when [tex]D=b^2-4ac < 0\\[/tex]

touches the x-axis at one point, when [tex]D=b^2-4ac =0[/tex]

intersects x-axis at two points, when [tex]D=b^2-4ac > 0\\[/tex]

For the function[tex]y=4x^2+20x+25[/tex]  the discriminant D is,

This means that the graph of the function touches the x-axis at one point.

[tex]D=20^2-4(4)(25)=200-200=0[/tex]

Since [tex]y=4x^2+20x+25=(2x+5)^2[/tex]then the tangent point has x-coordinate at x=-2.5  (value at which y=0).

Therefore the correct choice is B.

The graph of the function f(x) = 4x² + 20x + 25 passes through the  x-axis at  –2.5.

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The function is given as

f(x) = 4x² + 20x + 25

On factorization, we have

f(x) = 0

Then

           4x² + 20x + 25 = 0

   4x² + 10x + 10x + 25 = 0

2x (2x + 5) + 5 (2x + 5) = 0

           (2x + 5)(2x + 5) = 0

                      (2x + 5)² = 0

Then the graph of the function passes through the x-axis at –2.5.

The graph is shown below.

Answer:

A negative number.

Step-by-step explanation:

For example, -5+-3 is -8. This is because as you add negative numbers, you go further down the number line, therefore it becomes smaller and a small negative number has a bigger number in front of the minus sign.

Answer:The correct statement comparing modes to ranges is ''The modes differ by 40 and the range differs by 40'' is true.

Step-by-step explanation:The table below shows the number of pages in each book he read last summer and the number of pages in each book he read this summer.

Number of Pages   Elias Read during the Summer,

Last summer: 140 220 190 180 190

This summer: 150 170 150 190 180

We have to determine,

Which statement comparing the modes to the ranges is true.

According to the question,

The mode of a data set is the value that occurs most often.

The data from last summer,

The value 190 is in the list twice, while all other values are only in once.  This means 190 is the mode.

The data from this summer,

The value 150 is in the list twice, while all other values are only in once.  This means 150 is the mode.

The difference in modes is 190 - 150 = 40.

The range is the difference between the maximum and minimum values in a data set.

The maximum value is 220 and the minimum value is 140,

Then,

Range = 220 - 140 = 80

The range for this summer's data,

The maximum is 190 and the minimum is 150;

Then,

Range = 190 - 150 = 40 for the range.

Therefore,

The difference in ranges is 80 - 40 = 40.

Hence, The modes differ by 40 and the range differs by 40
