Answer:
18
Step-by-step explanation:
3/1 x 6/1 = 18/1 = 18
Divide 60 by 2/3 to find the class total.
= 60 ÷ 2/3
to divide fractions, multiply by reciprocal of 2/3
= 60 * 3/2
multiply numerators
= (60 * 3)/2
= 180/2
= 90 total students
CHECK
= 90 total * 2/3
= (90*2)/3
= 180/3
= 60 which is 2/3 of class
ANSWER: There are 90 total students
Hope this helps! :)
Answer:
Median
Step-by-step explanation:
Median divide a frequency distribution in two equal halves. Median lies at the mid point of any frequency distribution data of any values or quantities.
For example if we have any distribution as [5,7,10,15,8,6.65,12,15,2,3] here 6 will be the median of the distribution as 6 lies at the mid point of the distribution
Answer:
y = 20*4^x
Step-by-step explanation:
to find the value of the constants a and b, we just need to use the points given in the equation and solve the system of equations:
point (0,20): x = 0 and y = 20:
20 = a*b^0 = a*1 = a
a = 20
point (2,320): x = 2 and y = 320
320 = 20 * b^2
b^2 = 16
|b| = 4
b = 4 or b = -4
So we have two exponencial equations that pass through these points:
y = 20*4^x and y = 20*(-4)^x
As the questions asks for just one equation, we can answer y = 20*4^x
