Step-by-step explanation:
Given the data on the result of math exam in Ben's class
{35,42,56,68,69,72,72,77,78,78,82,85,87,88,90,93,94,96,96,99}
The 85th percentile score represents the score in which 85 percent of the students in Ben's class or below obtained in the test.
The 85th percentile score :
85%(n+ 1) term
n = number of observations = 20
0.85(20 + 1)th term
0.85(21) = 17.85 term
Take the average of the 17th and 18th terms
(94 + 96) / 2
= 190 / 2
= 95
Answer:
(18, 25 )
Step-by-step explanation:
The translation rule
(x, y ) → (x + 3, y - 7 )
means add 3 to the original x- coordinate and subtract 7 from the original y- coordinate, then
(15, 32 ) → (15 + 3, 32 - 7 ) → (18, 25 )
Answer:
El lado del cuadrado es de 20 my el área del cuadrado es de 400 metros cuadrados. Paso a paso ... El perímetro de un cuadrado es 80 m. ¿Cuál es la longitud de cada lado del cuadrado ... Para celosía & lt; L, * & gt; si a, b, ce L thena + (a e b) = a se llama.
Step-by-step explanation:
Well, Gina makes quite a bit to be a waitress...but let's focus on the math!
We can make an equation based on the information given to us...
$6.00 per hour
PLUS tips
Now, notice how <u>6.00 is a constant</u>, it never changes.
Her tips and her hours do change, however, so they must be made into variables.
We can form the equation 6(times how many hours) + (tips)
OR
<em>6x + y = z</em>
X - hours
Y - tips
Z - total money earned
Now we know what the variables mean, let's put these into action!
6(37) + 43 = Z?
Simplify: 6 * 37 = $222.00.
222 + 43 = Z
Simplify: 222 + 43 = $265.00
The total amount she earned altogether is $265.00!

First we have to find midpoint of R and S.
We can use formula such for it.
and
.
We obtained coordinates of point Q
and
Now, we can find the line equation using formula y=ax+b.
We can substitute coordinates of P and Q to this formula and solving system of equation get the answer.
After substituting we obtaind such system
From the system of equation we obtain result
Now we can put our resuts to general line equation.
