The population of an Asian country is growing at the rate of 0.7% annually. If there were 3,942.000 residents in the city in 199

Anettt [7]

Answer:

b) 4,000,000

Step-by-step explanation:

Let the population is measured since 1995,

Given,

The initial population, P = 3,942,000,

Annual rate of growing, r = 0.7% = 0.007,

If y represents the population after t years

So, the population after t years would be,

$y=Pe^{rt}$

$y=3942000(2.7)^{0.007x}$

Therefore, the population after 5 years,

$y=3942000(2.7)^{0.007\times 5}=3942000(2.7)^{0.035}=4081448.78924\approx 4000000$

Hence, the population in 2000 would be approximately 40,00,000.

Option 'b' is correct.

Find the area?????????

If we slice this down the middle and fit it together like a puzzle we'll get a rectangle base 9.6/2 and height 4.8+9 so area (9.6/2)(4.8+9) = 66.24 square units.

The correlation analysis assumes that the measurements have a bivariate normal distribution in the population. Select all of the

RoseWind [281]

Answer:

A. True

B. True

C. False

D. False

E. False

F. False

G. True

Step-by-step explanation:

Select all of the features that define a bivariate normal distribution.

(this means that we select only those that are properties of the bivariate normal distribution)

A. Bell-shaped probability distribution in two dimensions rather than one

TRUE because any combination of the two is still normal Z(x,y)=aX+bY

B. A relationship between X and Y that is not linear

TRUE The contours of the distribution are ellipses.

C. The presence of outliers

FALSE possible, but not always.

D. Either X or Y has a decidedly skewed distribution

FALSE normal distributions are symmetric

E. A relationship between X and Y that is linear

FALSE see answer to B

F. A cloud of points that is funnel shaped (wider at one end than the other)

FALSE normal distributions are symmetric

G. The frequency distributions of X andY separately are normal

TRUE For example, in Z(x,y)=aX+bY, putting a or b=0 means that X and Y separately are normal.

A new sidewalk will be 5 feet wide, 100 feet long, and filled to a depth of 3 inches (0.25 foot) with concrete. How many cub

GarryVolchara [31]

Answer:

4.63 cubic yard.

Step-by-step explanation:

Given,

The length of sidewalk, l = 100 feet,

Width, w = 5 feet,

Depth, h = 3 inches = 0.25 feet,

Thus, the volume of the concrete needed for making the sidewalk,

$V=l\times w\times h$

$=100\times 5\times 0.25$

= 125 cubic feet,

∵ 1 cubic yard = 27 cubic feet,

⇒ 1 cubic feet = $\frac{1}{27}$ cubic yard,

Thus, the quantity of concrete needed = $\frac{125}{27}$ ≈ 4.63 cubic yard.
