Answer:
18/28, or percentage wise, approximately 64.2%
Step-by-step explanation:
Take the seniors and divide it by the total # of students, and you got your probability!
Answer:
1/4
Step-by-step explanation:
y2-y1/x2-x1
6-5/ 0 - -4.... since it's two subtract signs facing each other you turn it into a +..... 1 /4
Answer:
slope = 1
y-intercept = (0 , -4)
x - intercept = (4 , 0)
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
Note that there is no number besides the x. When this happens, the slope is to be assumed as 1.
The number (and sign) that replaces the b is the y-intercept. In this case, it is (0 , -4).
The x-intercept is the point in which you intercept the y-line at 0. Plug in 0 for y, and solve for x:
0 = 1(x) - 4
0 = x - 4
0 (+4) = x - 4 (+4)
x = 4
x-intercept = (4 , 0)

answer
D ∩ (E ∩ F) = 4
Answer:
x = 5
Step-by-step explanation:
2² x 2³ = 2^x
Laws of indices states that when the base is same the powers can be added when two terms are multiplied,
2^(2+3) = 2^x
2⁵ = 2^x
x = 5
