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.
Answers
Answer:
All of the batches of the new blend of concrete made at their plant in a particular week.
Step-by-step explanation:
The population refers to all the subjects or data which which meets the condition or requirement of a certain experiment or research. This means that all the set of similar items or subjects which is of interest in a certain study is the population. In the scenario above, the population will be the set of all the new blend concrete which are made in the plant within a certain week. Thereafter, if a sample is required it will be drawn from these set of data or observation.

Answer:
m = 6[tex]\sqrt{3}[/tex] , n = 6
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and exact values
cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] , sin30° = [tex]\frac{1}{2}[/tex] , then
cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{m}{12}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
2m = 12[tex]\sqrt{3}[/tex] ( divide both sides by 2 )
m = 6[tex]\sqrt{3}[/tex]
and
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{n}{12}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2n = 12 ( divide both sides by 2 )
n = 6
if the mean of 12,16,22,X 28 is 19.6 find X
Answers
Answer:
20
Step-by-step explanation:
A data is given and the mean of data is 19.6 .The data is ,
12 , 16 , 22 , x , 28 .
We know that the mean is sum of observations divided by Total number of observations . So that ,
⇒ 12 + 16 + 22 + x + 28/ 5 = 19.6
⇒ 78+x/5 = 19.6
⇒ 19.6 × 5 = 78 + x
⇒ 78 + x = 98
⇒ x = 98 - 78
⇒ x = 20
Hence the value of x is 20 .the quality rating of 8 movies showing at a movie theater near you is 5.6, 7.9, 7.0, 5.9, 7.8, 6.2, 6.4, and 5.2. What do the ninth movies need to be for the theater to average a movie rating of 6.4?
Answers
Answer:
5.6
Step-by-step explanation:
Given :
Quality rating for 8 movies :
5.6, 7.9, 7.0, 5.9, 7.8, 6.2, 6.4, 5.2
Let rating for the 9th movie = x
Average quality rating olfor the 9 movies = 6.4
To find x :
Sum of all ratings / number of ratings = 6.4
(5.6 + 7.9 + 7.0 + 5.9 + 7.8 + 6.2 + 6.4 + 5.2 + x) / 9 = 6.4
(52 + x) / 9 = 6.4
52 + x = 57.6
x = 57.6 - 52
x = 5.6

Two of the angles in a triangle measure 57° and 73°. What is the measure of the third angle?
Answers
Answer:
The third angle is 50°
Step-by-step explanation:
In a triangle, all the angles must add up to 180° such that:
[tex]180= a+b+c[/tex] where a , b, and c are all angles
Since we know that two of the angles are 57° and 73°, we can subtract them from 180° to find the third angle.
Using the above equation, we can rearrange it to solve for the missing value:
180°= a + b + c
180°=57°+ 73° +c Substitute the angles in for any 2 variables
180°- 57°-73°= c Rearrange the equation to solve for last variable
50°= c
The third angle is 50°

Answer:
(x - 3)² + (y - 2)² = 16
Step-by-step explanation:
The center of the circle is (3, 2).
The radius of the circle is 4.
(x - 3)² + (y - 2)² = 4²
Answer: (x - 3)² + (y - 2)² = 16
The complete equation of this circle with center (3, 2) and radius 4 units is
(x - 3)² + (y - 2)² = 4²
Used the concept of the equation of the circle which stated that,
The standard form of the equation of a circle is,
(x - h)² + (y - k)² = r²
Where, (h, k) is the center of the circle and 'r' is the radius of the circle.
Given that,
The center of the circle is (3, 2).
And, The radius of the circle is 4.
Here, (h, k) = (3, 2)
And, r = 4
Substitute all the values in the standard form of the equation of a circle,
(x - 3)² + (y - 2)² = 4²
Therefore, the equation of a circle,
(x - 3)² + (y - 2)² = 16
