Answer:
a) 2.0702
b) 2.07
Step-by-step explanation:
Given:
Sample, n = 840
standard deviation, σ = 60
a) The standard deviation of the sampling distribution, will be:
= 2.0702
Standard deviation of the sampling distribution is 2.0702
b) According to the 68 part of the 68-95-99.7 rule, 68% of all values of x fall within 1 standard deviation on either side of the unknown mean μ.
Therefore, missing number will be:
![1 * [\frac{\sigma}{\sqrt{n}}]](https://tex.z-dn.net/?f=%201%20%2A%20%5B%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%5D%20)
= 1 * 2.0702
= 2.0702 ≈ 2.07
Answer:
200G
Step-by-step explanation:
Answer:
<em>5</em><em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>/</em><em>4</em>
<em>X </em><em>=</em><em> </em><em>2</em><em>0</em><em> </em>
<em>hope</em><em> </em><em>it</em><em> </em><em>helps</em><em> </em><em>u</em><em> </em><em>if </em><em>yes</em><em> </em><em>then</em><em> </em><em>foll</em><em>ow</em><em> me</em>
X = 50 (Is parallel to the y-axis so there is no intersection point)
Y= 40 (Is parallel to the x-axis so there is no intersection point)
Both no intercept with the other
The y intercept is the y value determined when x = 0
y = -0 - 5
y = - 5
The y intercept is (0,-5)
The x intercept is where y = 0
0 = -x - 5
5= -x
x = - 5
The x intercept is (- 5, 0)
