Answer:
p = 10 7/15
Step-by-step explanation:
p - 3 1/5 = 7 1/3
add -3.20 to both sides
p = 10 7/15
Answer:
The value of the expression is - 5.
Step-by-step explanation:
(-2x +10) - (-6x + 5y + 12) + (x +8y - 16)=
-2x+10+6x-5y-12+x+8y-16=
(-2x+6x+x)+(-5y+8y)+(10-12-16)=
5x+3y-18
if x=5 and y=-4 then
5*5+3*(-4)-18=25-12-18=25-30=-5
draw a perpendicular line from the directrix passing through the focus, this will be the line of symmetry.
The vertex(h, k) will be located on the line half way between the focus and directrix.
The distance from the focus to the vertex is called the focal length, call it a. The then equation is
(x - h)^2 = 4a(y - k)
the equation can be manipulated to
y = 1/4a(x - h)^2 + k

Answer:
Step-by-step explanation:
The hypothesis being tested is:
H0: ρ = 0
Ha: ρ ≠ 0
Pearson's r is -0.140.
The critical r-value is 0.404.
Since 0.140 < 0.404, we cannot reject the null hypothesis.
Therefore, we cannot conclude that notebook computer use and grades are related.
Pearson's r is -0.140. It means that there is a weak negative relationship between notebook computer use and grades.
The coefficient of determination is 0.020. 2% of the variation in the model is explained.
The relationship is not significant.
