The slope is -2:) hope this helped!!
Answer:
see explanation
Step-by-step explanation:
On each median the distance from the vertex to the centroid is twice the distance from the centroid to the midpoint, or
the distance from the centroid to the midpoint is one third of the median

LF = 2 × HL = 2 × 30 = 60
HF = HL + LF = 30 + 60 = 90

KL = KE = × 15 = 5
LE = 2 × KL = 2 × 5 = 10

LJ = DL = × 24 = 12
DJ = DL + LJ = 24 + 12 = 36

Step-by-step explanation:
Answer:
68%
Step-by-step explanation:
Given that:
Mean speed (m) = 46
Standard deviation (s) = 13
Approximately what percentage of vehicle speeds were between 33 and 59 mph
Obtain the Zscore for P(Z < x) for both values and subtract :
For x = 33
Zscore :
Z = (x - m) / s
Z = (33 - 46) / 13 = - 1
p(Z < - 1) = 0.15866 ( Z probability calculator)
For x = 59
Zscore :
Z = (x - m) / s
Z = (59 - 46) / 13 = 1
p(Z < 1) = 0.84134 ( Z probability calculator)
Hence, 0.84134 - 0.15866 = 0.68268 = 0.68
0.68 * 100% = 68%
Answer:
They can seat <u>520</u> students.
Step-by-step explanation:
Given:
The night school auditorium is able to seat 8 elementary school groups of 65 students each.
Now, use the distributive property to determine the number of students they can seat.
Total number of elementary school groups = 8.
Number of students in each group = 65.
So, using the distributive property to get the number of students they can seat:
Therefore, they can seat 520 students.
