Answer:
3/4 probability
probability to draw a red card = 11/26
probability to draw a diamond =1/4
probability of drawing one or other card = 35/52
# actually i am not sure
Explanation:
To determine the slope and y-intercept of the equation, let us plot the coordinates in the slope-intercept form.
Analyzing the graph, some of the points that are on the straight line is (1,0),(3,5), (9,20)
Let us consider the points (1,0),(3,5) to determine the slope.
Since, the profit is earned in thousands of dollars, m = 2.5 or m = 2500
Thus, slope = 2500
To determine the y- intercept, let us substitute any one of the coordinate from the graph.
Thus, let us substitute (1,0) in the equation to determine the y-intercept.
Simplifying, we have,
Hence, the line of best fit equation is
2A)
C is correct.
2B) If x + 13 = 28, solve.
If x = 15 and x + 13 = 28, you can solve it two ways:
1. Plug x into 4x + 26 to get a perimeter of
86, or
2. Redo the equation:
3a. Since the 6z is negative, you want an expression the has 5z - (11z). Answers A and D have that in their answer.
But since the 13 is positive, you want the answer that subtracts the smaller number from the larger. Thus,
D is your answer since it subtracts 2 from 15.
3b) You think about this question the same way; 6z is positive, so the smaller number is being subtracted from the larger, meaning that 11z - 5z is what you look for. C and D are the two that have that, so now let's look at the second term.
The 13 is negative, so you want the answer that has 2 - 15. The answer that has that is
D.
Hope this helps :D
Answer:
24.75
Step-by-step explanation:
2x-11 + 6x-7 =180
8x-18=180
8x=198 /8
x=24.75
