Answer:
Step-by-step explanation:
Given that a large trucking company wants to estimate the proportion of its tracker truck population with refrigerated carrier capacity.
Sample size n =200
Sample proportion p = 0.30
q = 1-p =0.70
Std error =
For 90% confidence interval, Z critical = ±1.645
Hence margin of error = ±1.645(0.0324) =±0.0533
Confidence interval = 0.30±0.0533
= (0.2467, 0.3533)
X-2/3x= - 1/7 is equivalent to the equation above. Then you get 1/3x= - 1/7.
So, x = - 3/7

A solid machine part is to be manufactured as shown in the figure. The part is made by cutting a small cone off the top of a larger cone. The small cone has a base radius of 3 inches and a height of 5 inches. The larger cone has a base radius of 9 inches and had a height of 15 inches prior to being cut. What is the volume of the resulting part illustrated in the figure?
C. 390 cubic inches
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. ... Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line.
