Answer:

w = 7m

l =9 m

Step-by-step explanation:

Let w = width

l = w+2

A = l*w

63 = (w+2) * w

63 = w^2 +2w

Subtract 63 from each side

0 = w^2 +2w - 63

Factor

What 2 numbers multiply to -63 and add to 2

9*-7 = -63

9-7 = 2

0 = (w +9) ( w-7)

Using the zero product property

w+9 =0     w-7 =0

w = -9        w = 7

Since we cannot have a negative length

w=7

l =w+2 =7+2 = 9

The data below are the ages and systolic blood pressures (measured in millimeters of mercury) of 9 randomly selected adults. Age
Ipatiy [6.2K]

Answer:

156

Step-by-step explanation:

Given the data:

Age (X) :

38

41

45

48

51

53

57

61

65

Pressure(Y) :

116

120

123

131

142

145

148

150

152

From the data, we could obtain a regression equation to mod the data Given using a linear regression calculator :

The regression equation obtained is :

y = 1.48769X + 60.46103

Using the model, the predicted blood pressure for a person aged 64 will be :

y = 1.48769(64) + 60.46103

y = 95.21216 + 60.46103

y = 155.67319

y = 156 (nearest whole number)
