Answer:
-15/2 or -7.5 or -7½
Negative StartFraction 15 Over 2 EndFraction
Step-by-step explanation:
Slope or gradient of a line is the ratio of change in y co-ordinates to the change in x co-ordinates.
Therefore;
M=∆y÷∆x
The change in y co-ordinates is given by
∆y=y2-y1
Similarly, change in x co-ordinates is given by
∆x=x2-x1
Given the two points as (5, 80) and (7, 65)
X1=5 Y1=80
X2=7 Y2=65
∆y=65-80=-15
∆x=7-5=2
Hence ∆y÷∆x will be -15÷2=-7.5 or -7½
Negative StartFraction 15 Over 2 EndFraction
Answer:
"a quotient of a number and 6" refers to n6 or n÷6 .
Step-by-step explanation:
r. Let's let n be the "number". Therefore, "a quotient of a number and 6" refers to n6 or n÷6 .
Answer: The four integers are: 6,8,11 and 14
Step-by-step explanation:
The attachments below contains step-by-step explanations of the guessing and checking approach that would be used to arrive at the answer.
The calculations on the attachments is from left to right.
For this case we have different effectiveness using two conditions the first one with to students who chose the professor as the chair of their doctoral committe and the second is associated to all students and we see a different effectiveness
This is a clear example of an error in the A)Data Gathering Phase
And the reason is because they introduce bias in the study just selecting students who select the professor as the chair of their doctoral committee, and it's very evident when they select all the students the real results change
Find area of circle
A=pir^2
A=pi5^2
A=25pi
then find how much the central angle is
whole circle is 2pi radians
(3pi/2)/2pi=3pi/4pi=3/4
it is 3/4 of whole area
area=25pi units^2
3/4 times 25pi=75/4pi units^2=
18 and 3/4 pi square units=
18.75ip square units
