Alika [10]

Answer:

C) 0.45

Step-by-step explanation:

Given that a population mean is 0.45, standard deviation is 0.001 and margin of error stands at 0.5% we have the following

0.45 + 0.001 = 0.451

Population mean with standard deviation is 0.451.

0.451 * 0.5% = 0.448745

We now reduce the number to two decimals and get the final marigin of error

0.45 as result

Further explanation:

When two triangles are congruent, then their respective sides will also be congruent or equal

As it is given that

ΔABC≅ΔDFE

Which means that

EF = BC

ED=AC

FD=AB

Now,

$EF=BC\\Putting\ the\ values\\x+15=2x+5\\x-2x=5-15\\-x=-10\\x=10\\AND\\FD=AB\\Putting\ the\ values\\4y=8y-20\\4y-8y=-20\\-4y=-20\\\frac{-4y}{-4}=\frac{-20}{-4}\\y=5\\AND\\ED=AC\\10z-5=3z+9\\10z-3z=9+5\\7z=14\\\frac{7z}{7}=\frac{14}{7}\\z=2$

Hence, the values of x, y and z are as follows:

x=10

y=5

z=2
