Mathematics

Answer:

D

Step-by-step explanation:

There are 4 queens out of 52 cards in a deck. Therefore, if each card has the same probability of getting chosen, you have a 4/52 = 0.077 chance of drawing a queen because there are (4 favorable outcomes/queens) / (52 total outcomes)

what are the ex and Y coordinates of point E, which partition the directed line segment from A to B into a ratio of 1:2?
Paul [167]

Answer:

Step-by-step explanation:

The formula for this is the one we use when we are given the ratio the directed line segment is separated into as opposed to the point being, say, one-third of the way from one point to another. The 2 equations we use to find the x and y coordinates of this separating point are:

x=\frac{bx_1+ax_2}{a+b}  and  y=\frac{by_1+ay_2}{a+b} where x1, x2, y1, y2 come from the coordinates of A and B, and a = 1 (from the ratio) and b = 2 (from the ratio). Filling in for x first:

x=\frac{2(2)+1(-4)}{1+2}=\frac{4-4}{3}=0 and then y:

y=\frac{2(-3)+1(9)}{1+2}=\frac{-6+9}{3}=\frac{3}{3}=1

The coordinates of point E, then, are (0, 1).

Does this graph represents a function? Why or why not?
love history [14]

Answer:

B. Yes, because it passes the vertical line test.

Step-by-step explanation:

B. Yes, because it passes the vertical line test.

A vertical line going from left to right will intersect at most one point on the graph at a time. That makes it a function.

A-3b=4;2a=6b-9 Answer by elimination. Please include how you got to the solution. Apparently there is a solution to this problem
AleksandrR [38]

Answer:

Step-by-step explanation:

a - 3b = 4 ---------------(eq1)

2a = 6b -9

or, 2a - 6b = -9 ------------(eq2)

    2a - 6b = 8 --------(eq1) X 2

   2a - 6b = -9 --------(eq2)

(-)       (+)       (+)

_________________________________

the variable part of both the equations are same. so the equation has more than one solution.
