Answer:
R = 20
Step-by-step explanation:
mean age = sum of ages/no. of men
sum of ages of the men that left = 55 + 63 = 188
remaining sum = 50R - 118
remaining no. of men = R - 2
now mean age = 50 - 1 = 49 years
49 = 50R-118/R-2
49(R - 2) = 50R - 118
49R - 50R = -188 - 98
-R = -20
R = 20
Answer: -6.1
Step-by-step explanation:
Answer:
Step-by-step explanation:
∠y=142°
∠x=180-142=38°
Answer:
Part a)
We need to find the equation of the line with a slope of -5 and a y-intercept of (0,3)
Part b)
The information that we have; we know the value of he slope, -5, and the y-intercept (0,3).
Part c)
strategies to use;
we can use the standard form of the equation of a straight line in slope -intercept form;
y=mx+c
Step-by-step explanation:
We have been given the slope is -5, thus the value of m is -5. moreover, the y-intercept is given as, (0,3) thus c is 3.
Final answer to the problem is;
y=-5x+3
