Rick wants to use multiplication to solve k=7÷1/3

Find the distance betwen the folowing points.

sveticcg [70]

Answer:

a. 5

b. 5

c. 6√2

d. √34

e. 43 (appx.)

Step-by-step explanation:

The distance between two points on the coordinate plane having coordinate (x1, y1) and (x2, y2) is given by $\sqrt{(x1-x2)^{2}+(y1-y2)^{2}}$ .... (1)

a. Hence, the distance between points A(2,3) and point B(6,6) is $\sqrt{(2-6)^{2}+(3-6)^{2}}=5$ units. {Using equation (1)}

b. Coordinates of A and B in the Cartesian coordinate plane are (2,3) and (6,6) respectively.

Hence, the distance between A and B is $\sqrt{(2-6)^{2}+(3-6)^{2}}=5$ units.

c. Coordinates of A and B in the Cartesian coordinate plane are (-1,5) and (5,11) respectively.

Hence, the distance between A and B is $\sqrt{(-1-5)^{2}+(5-11)^{2}}=6\sqrt{2}$ units.

d. Coordinates of A and B in the Cartesian coordinate plane are (1,-2) and (-2,3) respectively.

Hence, the distance between A and B is $\sqrt{(1+2)^{2}+(-2-3)^{2}}=(34)^{\frac{1}{2}}$ units.

e. Coordinates of A and B in the Cartesian coordinate plane are (12,-12) and (-23,13) respectively.

Hence, the distance between A and B is $\sqrt{(12+23)^{2}+(-12-13)^{2}}=43$ units. (Approximate) (Answer)

The distance from the center of a round table top to the edge of the table top is 4 ft. What's the area of the table top?

son4ous [18]

C would be the answer because to find the area of a circle A=pi times radius squared and you put that in a calculator and get 50.24

In a population of bats living in a certain region, 30 percent have a wingspan greater than 10 inches. In a random sample of 80

Kisachek [45]

Answer:

The correct option is (e).

Step-by-step explanation:

In this case we need to determine whether there is any difference between the proportion of bats with a wingspan greater than 10 inches living outside the region from that of the bats living in the region.

The hypothesis can be defined as follows:

H₀: There is no difference between the proportion of bats with a wingspan greater than 10 inches living outside the region and of the bats living in the region, i.e. p - p₀ = 0.

Hₐ: There is a difference between the proportion of bats with a wingspan greater than 10 inches living outside the region and of the bats living in the region, i.e. p - p₀ ≠ 0.

The information provided is:

n = 80

X = 20

p₀ = 0.30

A z-test for single proportion will be used to perform the analysis.

Compute the sample proportion of bats living outside of the region having a wingspan greater than 10 inches as follows:

$p=\frac{X}{n}=\frac{20}{80}=0.25$
