Alex

Answer:

14.35 grams

Step-by-step explanation:

Amount left, in grams = (970 grams)(1.000 - 0.277)^m, where m is the number of minutes.  This is exponential decay.

Amout left = (970 grams)(0.723)^13 = (970 grams)(0.01475), or 14.35 grams

The data represent the age of world leaders on their day of inauguration. Find the​ five-number summary, and construct a boxplot
Mumz [18]

Answer:

Minimum value = 43, Q_1=52, Q_2=Median=61, Q_3=67, Maximum value = 69.

Distribution is negative skewed.

Step-by-step explanation:

The given data set is

44, 43, 67, 68, 57, 65, 52, 62, 69, 54, 53, 61, 67, 48, 65​

Arrange the data in ascending order

43, 44, 48, 52, 53, 54, 57, 61, 62, 65, 65, 67, 67, 68, 69

Divide the data in 4 equal parts.

(43, 44, 48), 52, (53, 54, 57), 61, (62, 65, 65), 67, (67, 68, 69)

Minimum value = 43

Q_1=52

Q_2=Median=61

Q_3=67

Maximum value = 69

Starting and end point of box plot represent the minimum and maximum value respectively. Box starts from the first quartile to the third quartile. A vertical line goes through the box at the median.

The shape of the distribution.

Normally distributed: If Q_3-Q_2=Q_2-Q_1

Positive skew: If Q_3-Q_2>Q_2-Q_1

Negative skew: If Q_3-Q_2

For the given data set

Q_3-Q_2=67-61=6

Q_2-Q_1=61-52=9

Since Q_3-Q_2, therefore the given distribution is negative skewed.

The midpoint AB is M (-1,1). If the coordinates of A are (-6,-3), what are the coordinates of B
Ratling [72]

Answer:

coordinates of B is ( 4,5)

Step-by-step explanation:

If there two points (x1,y1) and (x2,y2) on a plane then coordinates of mid point is given by

m = (x1+x2)/2  , (y1+y2)/2

Given

m = (-1,1)

A= (-6, -3)

we have to point b

let point b be (x,y)

Then m (-1,1) is given by (-6+x)/2 , (-3+y)/2

(-6+x)/2 = -1

-6 + x = 2*-1 = -2

x = -2+6 = 4

also

(-3+y)/2 = 1

=> -3 + y = 2

=> y = 2 + 3 = 5

Thus , coordinates of B is ( 4,5) answer
