Q1
————
16
π
Explanation:
To find the circumference of a circle, you need the radius.
Remember that the area of a circle is
A
=
π
r
2
Since we know the area, we can plug it in for
A
64
π
=
π
r
2

64
π
=
π
r
2

64
=
r
2
Take the square root of both sides to find the radius:
r
=
8
Now, use the circumference formula of
2
π
r
C
=
2
π
(
8
)
This simplifies to the circumference equalling
16
π

There are two bags containing only green and black marbles. Bag A has 8 black marbles and 8 green marbles. Bag B has 9 black mar

Troyanec [42]

Answer:

Event 4: 0/16 (no blue marbles in any of the bags) Event 2: 9/20 (black only) Event 3: 1/2 (for both) Event 1: 20/20 (black or green)

Step-by-step explanation:

2 bags have green and black.

A has 16 in total.

8 of each.

B has 20 in total.

9 black. 11 green.

%~LEAST LIKELY~%

Event 1: Absolute

It's talking about both marbles, so it doesn't matter which one you get, as long as you pick one of the two from the bag.

Event 2: Less likely

9/20 for only black versus 11/20 for only green.

Event 3: As likely as not

Both have the probability of 8/16 which simplifies to 1/2.

Event 4: Never

No blue marbles.

Gaps have no data in them. So the range 1-2 is a gap.

Clusters are groups of data that are right next to each other.

So the range 3-6 on your dot plot is a cluster, because there is a group of data there with no gaps.

Peaks are the greatest amount of data in the dot plot. 0 and 5 are the peaks because they both have the most data, 4.

Answer:

20 minutes

Step-by-step explanation:

The trains are separating at the rate of 80 +70 = 150 km/hour. The time required to be 50 km apart is then ...

time = distance/speed = (50 km)/(150 km/h) = 1/3 h = 20 minutes

The route that Verlonda takes from her house to a store is represented on the grid below. Which ordered pair represents a point

Vadim26 [7]

Answer:

(3.8)

Step-by-step explanation:

Given

See attachment for grid

Required

Which point is on Veronica's path

On the attached grid, I plotted each of the coordinate pair (i.e the given options, A to D) on the grid.

By observation. we can see that:

A is on the vertical line (y intercept)

B is on the second quadrant

C is just few points to the left of the given path

D represents Verlonda's house

<em>Hence, the required coordinate pair is: (3.8)</em>
