A bicycle factory installs about 400 tires per day. Tires are installed Monday through Friday for 8 hours per day. The manager o

f the factory estimates the number of properly installed tires per week using the process below.
In the first hour of work on Monday, 49 out of 50 tires were properly installed.

So, there were about 8(49) = 392 properly installed tires on Monday.

Considering 5 working days per week, 5(392) = 1,960 is the number of tires properly installed in one week.

Which best explains the validity of the results?

Answer:

The results are likely invalid because it is unlikely that the tires installed in one hour on Monday will represent the entire population of tires.

Step-by-step explanation:

Out of 8 hours, do you really think one hour will represent it all?

This is why the resutls are likely invalid ( also I took the quiz )

Answer: The results are likely invalid because it is unlikely that the tires installed in one hour on Monday will represent the entire population of tires.

What is the volume of the composite figure?
m_a_m_a [10]
We are asked to solve for the volume of the composite figures and the answer is the summation of the two volumes such as the volume of a triangular prism and volume of a rectangular prism. In order to solve this, we need to recall the following formulas:
the volume of triangular prism = 1/2* b*h*l  and solving the volume, we have it:
the volume of triangular prism = 1/2 * 15* 16*20 = 3600 units³
the volume of rectangular prism = l*w*h  and solving the volume, we have it:
the volume of rectangular prism = 20*15*12 = 2400 units³

The total volume of the composite figure is the summation of the two volumes such as:
total volume = 3600 + 2400
total volume = 6000 units²

The answer is 6,000 units².

kobusy [5.1K]

"Then I will need an average quality score of <u>3.28</u>  to meet 85.28 goal."

<u>Step-by-step explanation</u>:

  • current average quality score = 82
  • improvement on average quality score = 4% of 82

⇒ (4/100)\times82

⇒ 82/25

⇒ 3.28

The improved average quality score = 82+3.28 = 85.28

The employee needs an average quality score of 3.28 to meet the goal of 85.28

Use a calculator to find the values of the inverse trigonometric functions. Round to the nearest degree. sin–1 = __° tan–1(4) =_
elena-s [515]

Solution:

As 360°= 2 π Radian

1 Radian =\frac{180 degree}{\pi }  

1. Sin(-1)= Sin (\frac{-180 degree}{\pi } )

 = Sin (-57°16'22")=-0.84147

2.Tan^{-1}4=Tan(\frac{720}{\pi }})

=Tan^{-1} (229°54'32")

=75.963757 Degrees

3. Cos^{-1}(0.1)=Cos^{-1}(\frac{18}{\pi})=Cos^{-1}(\frac{63}{11})=

= Cos^{-1}(5°43'38")

= 84.26083 Degrees

alisha [4.7K]

Answer:

y = 0

Step-by-step explanation:

Since there is no indication of a shift in the graph of f(x) = 3cos(-0.25x), then the midline must be the normal midline for a cosine or sine function which is: y = 0.
