Answer:

19 = 9+10

Step-by-step explanation:

Or its 21 if that is the vine joke

9+10=?

9 = 3x3

10= 5x2

3 (from 3x3) x 5 (from 5x2) = 15

3 (from 3x3) x 2 (from 5x2) = 6

15+6=21

Therefore 9+10=21

ANSWER

1 bell shape

2 to find probability when sampling

EXPLANATION

1 In a normal distribution, the mode,mean and median are equal.

As a result, the distribution is neither skewed to the right or left.

The shape of the normal distribution looks like a bell.

That is why it is also called the bell curve.

2. The area under the normal curve is 1.

The line of symmetry of the bell shaped distribution divides it into two halves with area 0.5 each.

The normal curve is therefore used to find the probabilities of a sample distributions.

Write the standard equation of the circle with the given center and passes through the given point. Center (7,-2); Point= (1,-6)
vodomira [7]

Answer:

(x - 7)² + (y + 2)² = (2√13)²

Step-by-step explanation:

We already know that the center is at (7, -2), but must find the radius.  The radius is the distance between the points (7, -2) and (1, -6):

r = √ [6² + 4²] ) = √(36 + 16) = √52 = √4√13 = 2√13.

Then the desired equation is (x - 7)² + (y + 2)² = (2√13)²

Megan made a paper chain that was 4m long. Mason’s chain was 479 cm long. Who’s was the longest? By how much?
Mekhanik [1.2K]

Answer:

Look below

Step-by-step explanation:

Let's start by converting 4 m into cm:

4m * \frac{10^{2}cm}{1m}= 4*10^{2}cm=400cm

Since Megan's chain is only 400 cm long, Mason's chain is longer by 79 cm.
