Hello! based on this problem, 68 is component of a whole. To solve it, we have the right to write and also solve a proportion. Set it up like this:
68/x = 85/100
Cross main point the sections. 68 * 100 is 6,800 and also 85 * x is 85x. Therefore you acquire 6,800 = 85x. Now, division each side by 85 to isolate the x. 85x/85 cancels out. 6,800/85 is 80. Us can check this sdrta.net by multiply 80 by 85%. 80 * 85% (0.85) is 68. There"s our sdrta.net. 68 is 85% the 80.
You are watching: 68 is 85 of what number
what is the equation of the line the is parallel come the line y=-1/3x+4 and passes with the point(6,5)
Lines that room parallel have the exact same slope. Thus the heat of the equation the you room finding has the slope = -1/3 and an unknown value we can call b to produce the equation y=-1/3x +b.
Using the point which the line must pass (6,5), we have the right to plug x and y into the unknown equation to resolve for b, the y-intercept.
Dbecause girlfriend can’t add or subtract unequal terms for A and B an interpretation the equations wouldn’t change for C it would be 10x-15y no -3y D) x+y+x+y=2x+2y 2(x+y)= 2x+2y

Using formula for z-score ,
The z-value at x= 0.12 will certainly be
The z-value at x= 0.14 will certainly be
The p-value :
Hence, the probability the a randomly selected wire from firm A’s production will accomplish the specifications = 0.9544996
b) Sample dimension : n= 4
Using formula because that z-score ,
The z-value in ~ x= 0.12 will certainly be
The z-value in ~ x= 0.14 will be
The p-value :
The probability that all 4 in a randomly selected mechanism will meet the specifications = 0.9999366
