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.
The answer is ‘y=30’
i don’t really know how to explain it but multiply the first top number’-4x’ with all of the bottom numbers. Multiply the first number at the bottom ‘-10’ by all the numbers at the top.
-40x-20y=-140
-40x+28y=-100

Answer:
b=18, a=9√3
Step-by-step explanation:
30-60-90 rule
The slope of function A is 2 times the slope of function B.
<h3>Slope of a function</h3>
The slope of a function is defined as the rate of change of the function. Given the equation
F(x) = 6x - 1
The slope of the equation is 6
For the line passing through the points (4, -1) and (-1, -2) and (-2, -5) the slope is expressed as:
Slope = -5+2/-2+1
Slope =-3/-1
Slope = 3
This shows that the slope of function A is 2 times the slope of function B.
