Answer:
Step-by-step explanation:
Given : . The manufacturer of a refrigerator system for beer kegs produces refrigerators that are supposed to maintain a true mean temperature, 48°F, ideal for a certain type of German pilsner.
To Find : The owner of the brewery does not agree with the refrigerator manufacturer, and claims he can prove that the true mean temperature is incorrect.
Solution:
We are given that refrigerators that are supposed to maintain a true mean temperature, 48°F.
Claim : The true mean temperature is incorrect.
So, null hypothesis and alternate hypothesis will be :
So, Option D is true .
Answer:
Below.
Step-by-step explanation:
Substitute x = 3 into each polynomial and see if the value of the polynomial is zero. If it is zero then x-3 is a factor.
Try number 1:
a(x) = x^3 - 2x^2 - 4x + 3
a(3) = 3^3 - 2(3)^2 - 4(3) + 3
= 27 - 2(9) - 12 + 3
= 27 - 18 - 12 + 3
= 9 - 18 - 9
= 27 - 27
= 0
So a(x) has (x-3) is a factor of a(x)
The other 3 polynomials are solved in the same way.

<u>Given:</u>
<u />
⇒ Slope-Intercept Form: y = mx + b
<u>where:</u>
- m is the slope
- b is the y-intercept (when x = 0)
Substitute the given values:

Since they are congruent, cpctc,
just set the congruent parts equal to each other.
so 2x-20=30
and
15=3y-9
Answer:
20.3cm^2
Step-by-step explanation:
Bullseye has a circular shape. So area of a bulleyse = Pi x (radius) ^2
Díameter is 2 inches = 5. 08cm
But radius = diameter /2
Radius = 5.08cm /2
Radius = 2.54cm
Hence Area of bulleyse = 3.14 x (2.54) ^2
= 3.14 x 6. 451 cm^2
= 20.256 cm^2
=20.3cm^2 (to nearest tenth)
