Answer:
One third the difference between 3/4 and 2/3 is
Step-by-step explanation:
One third the difference of A and B =
Here, as given in the question:
Now, one third of the difference is :
Hence, one third the difference between 3/4 and 2/3 is
Answer:
h = 5 units
Step-by-step explanation:
Given that,
The area of the parallelogram, A = 35 unit²
In the attached figure, we can see that the base is 7 unit.
We know that,
Area of a parallelogram, A = b × h
So,
So, the value of h is equal to 5 units.
Question 7: B
Question 8: C
Question 9: C
She took a total of 60 minutes
she answered both mulitiple choice and extended response in the total time which is 60 minutes
she took 2 minutes on rach multiple choice question and 6 minutes for the extended response
let x=number of multiple choice questions
let y=number of extended response questions
we can deduce that
total time =x*2+y*6
60=2x+6y
also we can deduce
20=x+y
since 20 ia the sum of multiple choice and extended response
for part 2 we just solve the system of equations
60=2x+6y
20=x +y
lets multiply the second equation by 2 so we can get rid of x
60=2x+6y
40=2x+2y
subtracting the two equations from each other to yields
20=0 +4y
y=5
to get x we substitute in one of the equations we derived from question 1
x+y=20
substituting y for its value we get
x+5=20
x=15
Answer:
Option B) False
Step-by-step explanation:
We define the following terms:
Range:
It is the difference between the minimum and maximum value of data.
It is effected by presence of outliers.
Interquartile range:
It is the difference between the third quartile and the first quartile of data.
Variance:
where are data points, is the mean and n is the number of observations.
It is a measure of spread of the data. It is effected by presence of outliers as they increase the variation in the data.
Thus, the given statement is false.
