<span>You have to calculate z-scores for each of these values and then compare them with what is needed for the 80%tile on a Normal curve.
 
z = (value - mean)/(standard deviation) = (value-60.0)/0.5.
z= 1 has 84% of the values smaller.</span>

The sum of three numbers is 123. The third number is 4 times the first. The second number is 9 more than the first. What are the
Romashka-Z-Leto [24]

Answer:

Step-by-step explanation:

Let the first number = x

Let the second number = x + 9

Let the third number = 4x

Together they make 123

x + x + 9 + 4x = 123              combine the left

6x + 9 = 123                         Subtract 9 from both sides

6x = 123 - 9

6x = 114                                 Divide by 6

x = 114/6

x = 19

=================

First number = 19

Second number = 19 + 9 = 28

Third number = 4*19 = 76

For the Parabolay = (x – 7)2 – 3. the equation for the Line Of Symmetry is
devlian [24]

Answer:

x = 7

Step-by-step explanation:

y = (x – 7)^2 – 3

This equation is in vertex form

y = a(x-h)^2 +k

where (h,k) is the vertex

For a vertical parabola, the line of symmetry is x=h

x = 7
