Nice twist of similar questions.
There are 7*6*5=210 possible 3-digit numbers formed by digits 1-7 without repetition.
For numbers greater than 700, the first digit must be 7.
Of the 30, the last digit must be a 2,4, or 6 to be an even number, that leaves 3 possibilities for the last digit.
The middle digit can be any number of the remaining 5 digits.
So the number of qualifying candidates would be
1*5*3=15 (1 for the first digit, 5 choices for the second, and 3 choices for the last digit).
Probability of randomly choosing a qualifying candidate (>700 & even) is therefore 15/210=1/14
Answer:
For every table served, Bradley's pay increases by an average of 4
Step-by-step explanation:
The line of best fit for the graph is y = 4x + 25 ; where, y = total pay and x = tables served
Using the slope intercept relation : y = mx + c ; where, m = slope
y = 4x + 25 ; the slope of the graph is 4
This means the rate of change of x with respect to y is 4 ;
This means for every unit change in x ; y increases by 4
For every table served, total pay increases by 4
Answer:
Step-by-step explanation:
Slope of the trail is expressed as;
Slope = vertical distance/horizontal distance
Given
Vertical distance = 60metres
Horizontal distance= 300metres
Substitute
Slope = 60/300
Slope = 6×10/30×10
Slope = 6/30
Slope = 6×1/6×5
Slope = 1/5
Hence the slope of the trail in reduced fraction is 1/5
160, I think. SA=2(lw+lh+wh).
