Answer:

it is less than zx for set b.

Step-by-step explanation:

The z-score of a data value is the number of standard deviations it is away from the mean.

The mean of both set a and set b is the same.

The standard deviation of set a is larger than that of set b. This means that for any given data point in set a, it will be fewer standard deviations away from the mean than it would be in set b. This makes the second choice true.

AngleDFG and angleJKL are complementary angles. M angleDFG =x+5, and m angleJKL=x-9. Find the measure of each angle

kicyunya [14]

$Measures\ of\ complementary\ angles\ make\ sum\ equal\ to\ 90^{\circ}.\\\\
\angle DFG+\angle JKL=90^{\circ}\\\\
x+5+x-9=90\\\\
2x=90-5+9\\\\
2x=94\ \ \ |:2\\\\x=47^{\circ}\\\\
\angle DFG=x+5=47+5=52^{\circ}\\ \angle JKL=x-9=47-9=38^{\circ}$
