Answer:

a = 20.79cm ( 2 decimal places)

Step-by-step explanation:

find the length of the identical sides (i name it "x") first using Pythagoras theorem

$14.8^{2}$ = $x^{2} + x^{2}$

219.04 = $2x^{2}$

$x^{2}$ = 219.04/2 = 109.52

x = $\sqrt{109.52}$

now find a,

$a^{2}$ = $(\sqrt{109.52}) ^{2}$ + $(7.5 + \sqrt{109.52}) ^{2}$

$a^{2}$ = 109.52 + 322.7477 = 432.2677

a = $\sqrt{432.2677}$ = 20.791048

Unknown g (x) = ax + b and g (g (x)) = 16x - 15. Calculate the value of a and b.

goblinko [34]

G(g(x))=16x-15
means that when you subsituted g(x) for x in g(x), you got 16x-15

a(ax+b)+b=16x-15
distribute
xa^2+ab+b=16x-15d
we look at the x terms
therefor
xa^2=16x
a^2=16
a=-4 or 4
we will find out

look a constant terms
ab+b=-15
undistribute b
b(a+1)=-15

if a is -4 then
b(-4+1)=-15
b(-3)=-15
b=5

if a=4 then
b(4+1)=-15
b(5)=-15
b=-3

so
g(x)=-4x+5 or
g(x)=4x-3

if a=-4, b=5
if a=4, b=-3

Answer:

A. .1469

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

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 problem, we have that:

$\mu = 39269, \sigma = 2550$
