For 25, I would begin with working out the difference in price.

$450 - $360 = $90

Then, $450 is 100% of the cost, therefore we want to know how much it has decreased.

I would work out 1% of $450. [$450 / 100 = $4.50]

Now if we divide $90 (the change in cost) by $4.50, we can tell what percent of a decrease we have.

90 / 4.5 = 20

Therefore we have a 20% decrease.

Assume X is normally distributed with a mean of 5 and a standard deviation of 2. Determine the value for x that solves each of t
mihalych1998 [28]

Answer:

U = 5

S = 4

1.) P(X>x) = 0.5

Prob = 1-0.5 = 0.5

We have z = 0, that is the z score with the probability of 0.5

X = u + z(s)

= 5+0*4

= 5

2.) 1-0.95 = 0.05

Z score having this probability

Z = -1.64

X = 5-1.64*4

= 5-6.56

= -1.56

3.) P(z<1.0) - p(X<x) = 0.2

0.841345-0.2 = .641345

We find the z score given this probability

Z= 0.36

X = 5+0.36*4

= 5+1.44

= 6.44

4.) P(X<x)-P(Z<-.5)

0.95 = p(X<x)-0.308538

p(X<x) = 0.308538 + 0.95

= 1.258538

There is no x value here, given that the probability is more than 1.

5. 1-0.99/2 = 0.005

We get the z score value

= -2.58

U - 5 = 5-5 = 0

-x = 0-2.58(4)

X = 10.32

If you apply these changes to the linear parent function, f(x) = x, what is the equation of the new function?
Maru [420]

Answer:

A, g(x) = 7x + 5

Step-by-step explanation:

applying these translations to the parent function f(x) = x, we would get the following equation:

g(x) = 7x + 5

a vertical compression is written before the parent function (in this case f(x)=x), and a shift up is written next to the function. both of these are without parentheses

the answer would be A, g(x) = 7x + 5
