Answer:
17/25
Step-by-step explanation:
Convert the percentage to a fraction by placing the expression over 100
. Percentage means 'out of 100
'.
68/100
Factor 4 out of 68.
4(17)/100
Cancel the common factors.
Factor 4 out of 100
4 x 17/4 x 25
Cancel the common factor.
17/25
Answer:
2.7 and 99.6%
Step-by-step explanation:
In this question, we are asked to calculate the percentage of the population scores as a genius.
We proceed as follows;
z =( Mean - value)/standard deviation= (140 - 100)/15 = 2.6667 = 2.7
From normal probability table, given that z = 2.67, the probability is 0.9962
This means that the required percentage is 99.6%
Answer:
y = -2x + 5
slope = -2
y intercept = 5
Step-by-step explanation:
Slope intercept form of equation of line is given by y = mx + c
where m is the slope of line
c is the y intercept i.e point where given line intersect y axis.
________________________________________________
given equation 4x + 2y = 10
we have to re-write this equation in form y = mx + c
4x + 2y = 10
subtraction 4x from LHS and RHS
4x + 2y - 4x= 10 - 4x
2y = 10- 4x
we have to eliminate 2 from y for that we
divide LHS and RHS by 2 we
2y /2 = 10/2- 4x/2
y = 5 - 2x
rearranging it in y = mx+c form
y = -2x + 5
thus, m = -2 , c = 5
