If a parabola had a y-intercept of (0,5) and an axis of symmetry at x = 4, what other point must be on the graph? (hint: draw)
Serga [27]

Answer:

(8, 5)

Step-by-step explanation:

Let's take a look at the y-intercept, (0, 5).  If the axis of symmetry is x = 4, then the distance from (0, 5) is 4 units.  If we reflect this point (0, 5) about the axis of symmetry x = 4, the resulting point is (8, 5).  In other words, the distance from the y-intercept to the axis of symmetry is 4 units, and so the distance from the y-intercept must be 4 units plus 4 units, or 8 units.

The only answer choice that matches this is the second one:  (8, 5).

Ants have 6 legs. Katie and Lukas write equations showing the proportional relationship between the number of ants, a, and the n
krek1111 [17]

Answer:

A

Step-by-step explanation:

I agree with Katie because number is legs is directly proportional to the number of ants.

1 ant has 6 legs.

So, 2 ants have 6 *2 = 12

3 ants have 6*3 = 18

11. If you rolled a six-sided die 242 times, how many times would you expect an odd number to appear?
Ilia_Sergeevich [38]

The numbers on a six sided die are 1, 2, 3, 4, 5, 6.

Odd numbers are numbers that cannot divide 2 completely. Thus, the odd numbers here are 1, 3 and 5

Probability is expressed as

Number of favourable outcomes/total number of possible outcomes

The total number of possible outcomes is 6

The number of favourable outcomes is 3

Thus, the probability of rolling an odd number is

3/6 = 1/2

Thus, if the die is rolled 242 times, then the number of times you would expect an odd number to appear is

1/2 * 242 = 121 times
