The Foley Products Company has designed a new blend of concrete they believe will be twice as strong as their current high quality concrete. This new blend of concrete is believed to produce batches with a population mean strength of 15,000 psi and a population standard deviation of 2,000 psi. To validate this belief, they collect a random sample of 49 concrete batches out of all the batches produced at their plant in a particular week. The mean strength of the random sample of 49 concrete batches is measured to be 14,731 psi. Select the correct description of the population in this study.

Answer:

  m = 8 yd

Step-by-step explanation:

The triangles are similar, so ...

  EG/EF = DH/DF

  EG = m = EF(DH/DF) = (10 yd)(12/15)

  m = 8 yd

Answer:

195 sq. in.

Step-by-step explanation:

area = length * width

Answer:

12.4 ft  

Step-by-step explanation:

Use the Pythagorean Theorem to find the length of the diagonal of the rectangle:

(4 ft)² + x² = (13 ft)², or 16 + x² = 169 ft²

Then x² = (169 - 16) ft², and x = +√(153 ft²) = 12.4 ft

(This matches Answer C)

Answer:

D) 6^5 · 3^5

Step-by-step explanation:

(6 · 3)^5 = 1889568

A) WRONG

(5 · (6 · 3)) = 90

B) WRONG

9^5 = 59049

C) WRONG

6 · 3^5 = 1458

D) CORRECT

6^5 · 3^5 = 1889568

The equation to find the total surface area of the cylinder is S = 2π(9)(h) + 2π(9)².

As per the question, the diameter of the cylinder is given as 18 inches, so we can calculate the radius (r) by dividing the diameter by 2:

r = 18 inches / 2 = 9 inches

The height of the cylinder is given as 4 inches.

To find the total surface area of a cylinder, we can use the following equation:

Total Surface Area = 2πrh + 2πr²

Now we can substitute the values into the equation to find the total surface area:

S = 2π(9)(h) + 2π(9)²

Therefore, the required equation is S = 2π(9)(h) + 2π(9)².

Answer:

Area = 42 in^2

Step-by-step explanation:

here's your solution

=> divide above picture in two parts

=> rectangle and traingle

=> area of rectangle = length* width

=> area of rectangle = (5*6)in.

=> area of rectangle = 30 in^2

=> now, area of traingle = 1/2*base *height

=> area of traingle = 1/2*4*6

=> area of traingle = 12 in^2

=> area of figure = 30 in^2 + 12 in^2

=> Area = 42 in^2

hope it helps

Answer:

42 in.²

Step-by-step explanation:

We need to find the area of the rectangle and then the triangle and then add them up. For the rectangle its 6 x 5 = 30 and for the triangle its 6 x 4 = 24/2 = 12 *we have to divide by 2 because we are finding the area of a triangle*. So we add 30 + 12 = 42 so your answer is 42 in.²

Answer:

D

Step-by-step explanation:

A translation 4 units to the right and 6 units down means that all of the x values increase by 4 and all of the y values decrease by 6.

Adding 4 to all of the x values and subtracting 6 from all of the y values gives us the coordinates:

A' (-3, 0), B' (8, 3), C' (2, -9)

Answer:

9.55 in

Step-by-step explanation:

First of all we have to find the base area

base area = radius^2 x 3.14 = 10^2 x 3,14 = 100 x 3,14 =314 in^2

the volume of a cylinder is

V = base area x height

so the height is

V/base area

3000 : 314 = 9.55 in

Answer:2520 pounds can be eaten by a herd of 18 elk in one week.

Step-by-step explanation:

Given: A elk an eat 20 pounds of plants in one day .

Now , Quantity of plants eaten by a herd of elk  = (Quantity of plants eaten per day) x (Number of elks ) x (Number of days)

So, the quantity of plants a herd of 18 elk can eat in one week = 20 x 18 x 7   [1 week = 7 days]

= 2520 pounds

Hence, 2520 pounds can be eaten by a herd of 18 elk in one week.
