Answer:
9.80
Step-by-step explanation:
Given that a survey of sports fan was conducted counting no of persons whose favourite was football, baseball, basketball and hockey.
Given that 49 like football, 35 baseball, 11 basket ball and 5 hockey
We have to find ratio of football fans to hockey fans.
We find that hockey fans are 5 and football fans are 49
Ratio of football fans to hockey fans =49/5
=9.80
The ratio means if 9.80 football favourite persons are there there would be only one person whose favourite is hockey.
Answer:
4th quadrant
Step-by-step explanation:
Answer:
Step-by-step explanation:
A line goes through the points (-2, 4) and (8, 9). We see that x increases by 10 and y increases by 5.
Thus, the slope of this line is m = rise / run = 5/10 = 1/2 (the slope)
Starting with the point slope equation y - k = m(x - h) and substituting 9 for y, 8 for x and 1/2 for m, we get:
y - 9 = (1/2)(x - 8) (point-slope form)
y = (1/2)x + 5 (slope-intercept form)
For 9, the answer would be -4
And for 10, the answer should be 47°
Answer:
Number of year = 11.725 year (Approx.)
Step-by-step explanation:
Given:
Amount invested = $200
Interest rate = 6% (compounded semi annually)
Future value = 2 x Amount invested
Find:
Number of year
Commutation:
Future value = 2 x Amount invested
Future value = 2 x 200
Future value = $400
Number of year (Semi-annual) = 2n
Interest rate (Semi-annual) = 6% / 2 = 3%
So.
A = P[1+r]ⁿ
400 = 200[1+3%]²ⁿ
2 = [1.03]²ⁿ
n = 11.725 year
Number of year = 11.725 year (Approx.)
