Answer:
12 payemst of 66.66
Step-by-step explanation:
1300 - 500 = 800/ 12 = 66.66
A= (h(a+b))/2
multiply each side by 2
2A = (h(a+b))
divide each side by h
2A/h = a+b
subtract a from each side
2A/h -a = b
Answer:
84.13% probability a particular tire of this brand will last longer than 57,100 miles
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:

What is the probability a particular tire of this brand will last longer than 57,100 miles
This is 1 subtracted by the pvalue of Z when X = 57100. So



has a pvalue of 0.1587
1 - 0.1587 = 0.8413
84.13% probability a particular tire of this brand will last longer than 57,100 miles
Answer:
The time required is 15.97 second.
Step-by-step explanation:
Consider the provided information.
A skywalk is 90 feet beyond the canyon's edge and is 4080 ft above the canyon floor.
First find the distance between skywalk and canyon floor by using Pythagorean theorem.
Distance between skywalk and canyon's edge = 
Distance between skywalk and canyon's edge = 
Substitute h = 4080.99 in the provided formula.



Hence, the time required is 15.97 second.
Answer:
2 inches
Step-by-step explanation:
The scale means 1 inches on map equal 125 feet in real life
<em>We know in real life Jon lives 250 ft away from Max. 250 is twice of 125, hence in map</em>, it should be 1*2=2 inches.
On the map, it is 2 inches from Jon's home to Max's home.
