The spinner shown has eight equal-sized sections. The pointer lands on an even number 135 times out of 250 spins. Which of the f
forsale [732]

Answer:

A and D

Step-by-step explanation:

Here, we shall be evaluating the validity of the statements;

A. Yes, A is true

There are four even numbers 2,4,6 and 8 and 4 odd number 1,3,5,7; The landing should be equal at 125 each

B. This is wrong

It is supposed to land half of the number of time s which is half of 250 and that is 125

C.This is wrong

The numbers greater than 4 are 5,6,7,8

Now, the probability should be 4/8 = 1/2 and that is 50%

D. This is correct

Number of times we have a landing on odd numbers is 250-135 = 115

The experimental probability of landing on an odd number is thus 115/250 = 0.46 which is 46%

The graph shows two straight lines. The equation of line A is y = 2 - x Work out the equation of line B.
d1i1m1o1n [39]

Answer:

Step-by-step explanation:

The equation of a line can be easily found from the graph.  First, find two points on the line that intersect points on the graph, then plot the changes in the two axis in this manner (change in y)/(change in x), or rise/run.  Thus, the slope of this line is 5/3.  Then, the  b in y = mx + b is simply when the line intersects the y-axis, in this case -5.  Thus, the equation of the line is

y = -5/3x - 5

Hope it helps <3
