Answer:
4/16 = 2/8 = 1/4= 0.25
Step-by-step explanation:
Answer:
So the value of the test statistic is -0.85.
Step-by-step explanation:
We know that a sample of 1800 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 54% of the chips do not fail in the first 1000 hours of their use.
We get that:

We calculate the standar deviation:

We calculate the value of the test statistic:

So the value of the test statistic is -0.85.
Answer:
B is 4 because there is no other one digit number that is a common multiple of 4
Step-by-step explanation:
Let the time taken by computer for virus scan be, 'x' days
We are given that Computer A runs a virus scan in every 2.75 days and Computer B runs a virus scan in every 3.5 days.
<h3>Amount of work done by computer A⤵️</h3>
Amount of work done in one day = 
Amount of work done in x days = 
<h3>Amount of work done by Computer B⤵️</h3>
Amount of work done in one day = 
Amount of work done in x days = 
Since, They are doing the same work the amount of work done is 1.

Solve for x ~






➪ <em>Thus, the time taken when both computers run a virus scan at the same time again is, 1.54 days</em>
You are given the length of a rectangular prism of 3x^2, width of 2x and height of x^2 + 3x +5. You are required to find the volume of a rectangular prism. Using the equation V = l x w x h, we multiply the three dimensions.
V = l x w x h
V = (3x^2)(2x)( x^2 + 3x +5)
V = 2x (3x^4 + 9x^3 + 15x^2)
V = 6x^5 + 18x^4 + 30x^3
The volume of the rectangular prism is 6x^5 + 18x^4 + 30x^3.
