Find the area (probability) under the standard normal curve between z= -0.52 and z= 2.01 Show work Solution Look at a z-score table for a standard normal curve. The probabiliy of z = 2.01 is 0.4778 and 0.52 is =…
How would you graph 2x-3y<12 Solution Without the ability to draw a graph, it is a little difficult to answer this question. The inequality is bounded by the equation 2x-3y=12. This is a linear equation with positive slope (goes from…
In a normal distribution with mean 850 in standard deviation 120 find the probability that a data value picked at random is greater than 1169 show work! Solution Hi Jane I., Ah yes, there’s another of your copious questions. (At…
I need to know how many 1/4 pound hamburgers can you make from 3 1/2 pounds of ground beef. For a math problem, I am stuck on. Solution 3 1/2 = 7/2 (7/2)/(1/4) = (7/2)(4) = your answer
A rock is dropped into a pond, creating a circular ripple. The radius of the ripple increases steadily at 6 cm A toy boat is floating on the pond, 2.00 m east and 1.00 m north of the spot where…
The first term of the geometric sequence is 4, while 2 is the first term of an arithmetic sequence. And, if the common ratio of the geometric sequence equals the common difference of the arithmetic sequence and their third terms…
P(x) = 2x^4 – x^3 – 27x^2 + 16x – 80, with zeros: 4, -4 Solution The easiest way to do this is to use synthetic division to divide the factors associated with the zeros 4 and -4 into the…
What is 5 1/2 – 7 ? Adding and subtracting rationals Solution 5 1/2 – 7 = (11/2) – (14/2) = -3/2
Solution To find 8% of 45, first rewrite 8% as a decimal by moving the decimal point two places to the left to get .08. Next, the word “of” means multiply, so we have (.08)(45) which is 3.6. So 8%…
1) Define the intersection points. (Show how you get the points). 2) Shaded the region bounded. 3) Evaluate the area (show the calculations). Solution The intersection is found by equating the two curves f1(x) = f2(x) or x3+2×2=x+1 or x3+2×2-x-1…
