Answer:

3.188

Step-by-step explanation:

Given that :

Sample data: 26.5, 28, 30.2, 29.6, 32.3, 24.7

Sample standard deviation (s) = 2.728

Mean (mu) = 25

Tstatistic formula :

(x - mu) / (s/sqrt(n))

n = sample size = 6 ; s = 2.728 ; mu = 25

Sample mean (x) = (26.5 + 28 + 30.2 + 29.6 + 32.3 + 24.7) / 6

Sample mean (x) = 171.3 / 6 = 28.55

Tstatistic = (28.55 - 25) / (2.728 / sqrt(6))

Tstatistic = 3.55 / 1.1137013

Tstatistic = 3.1875692

Answer:

95% confidence interval for the population standard deviation of the lifetimes of the batteries produced by the manufacturer.

(8.889, 11.7106)

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 23

Mean of the sample x⁻ = 10.3

Standard deviation of the sample (s) = 2.4

Level of significance = 0.05

Degrees of freedom = n-1 = 23-1 =22

Step(ii):-

95% confidence interval for the population standard deviation of the lifetimes of the batteries produced by the manufacturer.

(10.3 -  2.8188 (0.50043) , 10.3 + 2.8188(0.50043)

(10.3-1.4106 , 10.3+1.4106)

(8.889, 11.7106)

final answer:-

95% confidence interval for the population standard deviation of the lifetimes of the batteries produced by the manufacturer.

Answer:

The equation in the slope-intercept form is:

Step-by-step explanation:

Given the equation

[tex]-2(3x+5y)=10[/tex]

We know that the slope-intercept form of a line equation is

[tex]y = mx+b[/tex]

where

Writing the equation in slope-intercept form

-2(3x+5y)=10

-6x -10y = 10

Add 6x to both sides

-6x -10y + 6x = 10 +  6x

-10y = 10 + 6x

Divide both sides by -10

-10y / -10 = (10 + 6x) / -10

y = -3/5x - 1

Thus, the equation in the slope-intercept form is:

Answer:

Option (2)

Step-by-step explanation:

Formula to get the surface area of a sphere is,

Surface area = 4πr²

Here 'r' = Radius of the sphere

We have to calculate the surface area of a sphere with radius r = 9 inches.

By substituting the value of r in the formula,

S = 4π(9)²

Therefore, Option (2) will be the correct option.

Answer:

B

Step-by-step explanation:

First isolate the variable, x. To do this, use inverse operations. The inverse operation of -4 is +4. So, add 4 on both sides of the equals sign. The positive 4 cancels out the negative 4 on the left side. Add 4 to the other side, -18, for -14. You are left with 7x = -14. Now to get rid of the coefficient, 7. The inverse of x7 is ÷7. So divide 7x by 7 to completely isolate x. On the right side, -14 is divided by 7 to get -2. You are left with x = -2. Wow that was a ted talk :P Anyway, hope this was helpful ^^ lmk if I need to clarify about anything :D Good day man

Answer:

v= 6km/h - 1km/h^2 * t

Step-by-step explanation:

From the information, it seems the runner is slowing down because the speed at 1st hour is 5km/h but at 3rd hour becomes 3km/h.

If v= velocity, v0= initial speed, t= time, and the a=acceleration then the function would be:  

v= v0 + a * t

To find the acceleration you need to do this equation:

acceleration= velocity1- velocity3 / t3-t1

a = (3km/h-5km/h)/ (3 hour- 1 hour)

a = (-2km/h)/2hour= -1 km/hour^2

After that, you need to find the initial speed. Try to put the 1st-hour variable into the full equation. It would look like this

v= v0 + a * t

5km/h= v0 + (-1 km/hour^2 * 1 hour)

v0= 5km/h + 1km/h

v0= 6km/h  

Then the full function would be:

v= 6km/h - 1km/h^2 * t

The graph would look like a backslash(\) from 5 gradually go down to 1.

The number of gingerbreads that Beth can be made from 4 boxes of raisins is 8 dozens.

Proportions are mathematical statements where two or more ratios are made to be equivalent to each other.

Number of raisins Beth uses for one gingerbread man = 2 raisins for eyes and 3 raisins for buttons.

Number of raisins used for 1 gingerbread man = 2 + 3 = 5 raisins

Beth buys 4 boxes of raisins, each with 120 raisins in it.

Total number of raisins Beth bought = 4 × 120 = 480 raisins

So, 1 gingerbread can be made from 5 raisins.

Let x be the number of gingerbreads made from 480 raisins.

Using proportion,

1 : 5 = x : 480

1 / 5 = x / 480

Applying cross multiplication,

5x = 480

x = 480 / 5

x = 96

96 gingerbreads or 96/12 = 8 dozens of gingerbread can be made.

Hence 8 dozens of gingerbreads can be made from 4 boxes of raisins.

Answer:

A. (0, 1) and (2, -2)

B. Slope (m) = -³/2

C. y + 2 = -³/2(x - 2)

D. [tex] y = -\frac{3}{2}x + 1 [/tex]

E. [tex] \frac{3}{2}x + y = 1 [/tex]

Step-by-step explanation:

A. Two points on the line from the graph are: (0, 1) and (2, -2)

B. The slope can be calculated using two points, (0, 1) and (2, -2):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 - 1}{2 - 0} = \frac{-3}{2} = -\frac{3}{2} [/tex]

Slope (m) = -³/2

C. Equation in point-slope form is represented as y - b = m(x - a). Where,

(a, b) = any point on the graph.

m = slope.

Substitute (a, b) = (2, -2), and m = -³/2 into the point-slope equation, y - b = m(x - a).

Thus:

y - (-2) = -³/2(x - 2)

y + 2 = -³/2(x - 2)

D. Equation in slope-intercept form, can be written as y = mx + b.

Thus, using the equation in (C), rewrite to get the equation in slope-intercept form.

y + 2 = -³/2(x - 2)

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

2y + 4 = -3x + 6

2y = -3x + 6 - 4

2y = -3x + 2

y = -3x/2 + 2/2

[tex] y = -\frac{3}{2}x + 1 [/tex]

E. Convert the equation in (D) to standard form:

[tex] y = -\frac{3}{2}x + 1 [/tex]

[tex] \frac{3}{2}x + y = 1 [/tex]
