Answer:
The value of the unit rate is 8
Step-by-step explanation:
we know that
To calculate the unit rate simply divide the first number by the second number
so

Convert mixed number to an improper fraction

substitute in the expression above

Answer:
AB = PQ
Step-by-step explanation:
ABC = PQR
The angles are equal and the segments are equal
for the angles
A = P
B = Q
C = R
For the segments
AB = PQ
BC = QR
AC = PR
Answer:
d. 0.133
Step-by-step explanation:
-Standard error is calculated using the formula:

#We substitute the given values in the formula to solve for E:

Hence, the standard error is 0.133 and the correct option is d
Answer:
Step-by-step explanation:
we have

This is the equation of a vertical parabola open downward
The vertex represent a maximum
Convert the quadratic equation into vertex form
step 1
Factor -2

step 2
Complete the square


step 3
Rewrite as perfect squares
----> equation in vertex form
The vertex is the point (1,5)
X = arctan(32/19)
x = 59.30 degrees.
You don't say if the answer needs to be rounded, so round it as needed.
