Answer:

Affects the width of a confidence interval, as the margin of error is a function of the sample standard deviation.

Step-by-step explanation:

When we have the standard deviation for the sample, the t-distribution is used to solve the question.

It does not affect the center of the interval, which is a function only of the sample mean.

Width of a confidence interval:

The width of a confidence interval is a function of the margin of error, which is:

[tex]M = t\frac{s}{\sqrt{n}}[/tex]

In which s is related to the sample standard deviation. Thus, since s and M are directly proportional, a higher standard deviation makes the interval wider, lower standard deviation makes the interval narrower, and thus, the sample standard deviation affects the the width of a confidence interval.

Answer:

  314 square inches

Step-by-step explanation:

The radius is half the diameter. If the diameter is 20 inches, the radius is 20/2 = 10 inches. The area is given by the formula ...

  A = πr²

Filling in the given values, we get ...

  A = 3.14×(10 in)² = 314 in² . . . . area of the circle

Answer:

n > -6 and n < 8! Heart it if it was helpful :D

Step-by-step explanation:

Okay! So n has to be bigger than -6, but smaller than 8. So the inequalities are n > -6 and n < 8!

Answer:

n > -6 and n < 8

bcoz the number n has to be in between -6 and 8,

it must be greater than -6 and less than 8

Answer:

I believe the correct answer is 8, if i'm incorrect tell me

Answer:

y = 27

Step-by-step explanation:

y/3 + 2 = 11

First subtract 2 from each side

y/3 + 2-2 = 11-2

y/3  = 9

Then multiply each side by 3

y/3 *3 = 9*3

y = 27

Answer:

Answer is below :)

Step-by-step explanation:

y/3 + 2 = 11 is the Expression

Only two steps:  

step 1 = subtract 2 from both the sides

y/3 = 9

Step 2 = multiply 3 from both sides

y = 27

I hope this solved your question.

Answer:

17150 ft²

Step-by-step explanation:

similar rectangles means that the scaling factor from one rectangle to the other is the same for every side. and so the relative ratio of length and width stays the same.

in our case now the 2 widths are 175 feet and 40 feet.

the scaling factor f from small to large is therefore 175/40 = 35/8.

width large = width small × f

length large = length small × f

the area of a rectangle is length × width.

we know the area of the small rectangle (896 ft²).

Asmall = 896 = length small × width small

now the area A of the large rectangle is

A = length large × width large =

= length small × f × width small × f =

= length small × width small × f² = Asmall × f² =

= 896 × (35/8)² = 17150 ft²

Answer:

The h and v represent the center of the circle at point (h, v), and r names the radius. Specifically, h represents the horizontal displacement — how far to the left or to the right the center of the circle falls from the y-axis.

Answer:

x = 3

y = 6

Step-by-step explanation:

Apply the angle bisector theorem to find both variables.

Based on the theorem, we would have the following:

✔️x/2 = 6/4

Cross multiply

x*4 = 6*2

4x = 12

4x/4 = 12/4

x = 3

✔️9/y = 3/(8 - y)

Cross multiply

9(8 - y) = 3*y

72 - 9y = 3y

72 = 3y + 9y

72 = 12y

72/12 = 12y/12

6 = y

y = 6

Answer:

I think C is correct answers im not sure though

The only given function that is an exponential decay function is;

C:  f(x) = ³/₂(⁸/₇)⁻ˣ

Now, the general formula for exponential decay function is;

f(x) = abˣ

where b is the decay factor.

Now, the decay factor which we will call the base of the exponent must be greater than 1 .

Also, the exponent x must be negative to be called an exponential decay function.

Looking at the given options, only Option C meets the criteria for an exponential decay function.

The given options are;

A) f(x) = ³/₄(⁷/₄)ˣ

B) f(x) = ²/₃(⁴/₅)⁻ˣ

C) f(x) = ³/₂(⁸/₇)⁻ˣ

D) f(x) = ¹/₃(-⁹/₂)ˣ

Answer:

112 yards

Step-by-step explanation:

Applying Pythagoras theorem,

Pythagoras theorem states that, in a right angle triangle, the square of the hypotenuse is equal to the sum of the square of the two other sides.

Mathematically, it is expressed as

a² = b²+c²................. Equation 1

Where a = Length of the diagonal, b and c = lenght of the two other sides

From the question,

Given: b = 50 yards, c = 100  yards.

Substitute these values into equation 1

a² = 50²+100²

a² = 2500+10000

a² = 12500

a = √12500

a = 111.8

a = 112 yards

Probability [Number of product more than 12] = 5 / 9

Step-by-step explanation:

Given:

Total number of products = 9

Number of product more than 12 = 5

Find;

Probability = Number of favourable outcomes / Number of total outcomes

Probability [Number of product more than 12] = Number of product more than 12 / Total number of products

Probability [Number of product more than 12] = 5 / 9

Answer:

  arc AC = 63°

Step-by-step explanation:

Arc BC is twice the measure of inscribed angle BAC, so is ...

  arc AC = 2×89° = 178°

The remaining arc of the circle is the difference between 360° and the sum of the other two.

  arc AC = 360° -119° -178°

  arc AC = 63°

Answer:

y  =  [tex]\frac{-8}{3}[/tex]x + [tex]\frac{62}{3}[/tex]

Step-by-step explanation:

Use slope formula.

then substitute slope for m in y = mx + b

pick a set of coordinates and substitute them in for x and y.

Solve for b

Answer:

[tex]y=-\frac{8}{3}x+\frac{62}{3}[/tex]

Step-by-step explanation:

Hi there!

Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x is 0)

1) Determine the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the points (7,2) and (10,-6)

[tex]m=\frac{2-(-6)}{7-10}\\m=\frac{2+6}{7-10}\\m=\frac{8}{-3}[/tex]

Therefore, the slope of the line is [tex]-\frac{8}{3}[/tex]. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-\frac{8}{3}x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=-\frac{8}{3}x+b[/tex]

Plug in one of the given points and solve for b

[tex]2=-\frac{8}{3}(7)+b\\2=-\frac{56}{3}+b[/tex]

Add [tex]\frac{56}{3}[/tex] to both sides to isolate b

[tex]2+\frac{56}{3}=-\frac{56}{3}+b+\frac{56}{3}\\\frac{62}{3}=b[/tex]

Therefore, the y-intercept is [tex]\frac{62}{3}[/tex]. Plug this back into [tex]y=-\frac{8}{3}x+b[/tex]:

[tex]y=-\frac{8}{3}x+\frac{62}{3}[/tex]

The measure of angle D and A must be equal.

Step-by-step explanation:

    ASA means angle-side-angle.  So you must have two angles and the side between them be congruent to the other triangle.  We already know Angle C and F are congruent and Side lengths AC and FD are congruent.  So we just need the angles on the other side of the side lengths.

Step-by-step explanation:

The graph shows a vertical line at x = -1, with points at y=-4 and y=5. The distance between the points is the difference of their y-coordinates:

You can count the grid squares between the points, if you like.

The distance between the points is 9 units.
