b = -0.5
4 + 2 = - 0.5 * 4 + 8
6 = -2 + 8
6 = 6
Which is true, Therefore the answer is -0.5
Answer:
1.2
Step-by-step explanation:
Given that X is Normally distributed random variable with an unknown mean μ and known standard deviation 6
Hence we can say for a sample of size 100, the sample mean will have a std deviation of = 
Since population std deviation is known we can use Z critical value for finding out the confidence interval
For 95% using (68-95-99.7 rules) we have z critical value =2
Hence margin of error =2(std error) = 1.2
Confidence interval 95%
Lower bound = Mean - margin of error = Mean -1.2
UPper bound = Mean +1.2
Hence , 95% of all of these values of x should lie within a distance of __1.2___ from μ .
Answer:500 I hope this helpful
Step-by-step explanation:
3000 divided by 48 times 8
To make the calculation easier, first multiply the numbers that result in multiples of 10
24000 divided by 48
Divide the numbers
=500
Answer:
Given - Radius of ring is 9 millimeters
To find - Circumference
Solution -
9 millimeters = 0.9 centimeters
Circumference of circle = 2 × pie × r
= 2 × 3.14 × 0.9
= 6.28 × 0.9
= 5.652

A trapezoid is a quadrilateral where at least one pair of opposite sides are parallel. Here Mr. Parker is graphing a quadrilateral, so he wants the quadrilateral to be a trapezoid. He has already graphed vertices at:

So these points have been plotted below. As you can see form the graph, points (3, 3) and (5, 3) has the same y-coordinates, so the line that passes through these two points has zero slope. The other point is (1, 1) so we can choose any point such that the slope of the the line that passes through (1, 1) and that point also has zero slope. Therefore, the 4th vertex is any point of this form:
