Answer:

10a. No

10b. No

10c. Yes

10d. Yes

Step-by-step explanation:

10a. This equation does not because 3/4 x 8 = 6 and not 9.

10b. This equation doesn’t because 3x8 does not equal 28.

10c. This equation does because 5 x 8 = 40 which means y = 8.

10d. This equation does because 8/2 = 4. Fractions are just division problems and 8 divided by 2 equals 4, meaning y = 8 was n this equation.

Find the 44th percentile, P44, from the following data! pls help

irina [24]

Answer:

$P_{44} = 29.9$

Step-by-step Explanation:

The 44th percentile, $P_{44}$ , of the given data can be calculated using the kth formula for percentile given as:

$i = \frac{k}{100}(n + 1)$

where,

i = the ranking or the position of the percentile = ?

k = the percentile = 44

n = total number of the given data values = 23

Plug in the values into the formula to find "i"

$i = \frac{44}{100}(23 + 1)$

$i = \frac{44}{100}(24)$

$i = \frac{1,056}{100}$

$i = 10.56$

Since "I", 10.56, is not an integer, round the number down, and round it up to the nearest integer, then look for the position each occupy in the ordered data set, and find their average.

Thus,

$i_{down} = 10.56 = 10$

$i_{up} = 10.56 = 11$

The data occupying the 10th position on the data set = 28.7

11th = 31.1

$P_{44} = \frac{28.7 + 31.1}{2} = \frac{59.8}{2}$

$P_{44} = 29.9$

A dance floor is shaped like a square with an area of 196 square feet. Find the length of one side of the dance floor.

GenaCL600 [577]

Since it's a square, the sides are all the same. This is going to be the equation.
S²=196
14×14=196
The length of one side is 14.

What's two thirds of a straight line?

Komok [63]

Well if the straight line is equal to 1 then your answer is 2/3 but if the straight line is not equal to 1 you need to know what it is equal to or you could use the equation y = (2/3)x
"x" would be the length of the straight line and "y" would be two-thirds of it

Help with #7 and #8?

arsen [322]

Answer:

M(6,5) and G(2,9)

Step-by-step explanation:

$m = ( \frac{x1 + x2}{2}, \frac{y1 + y2}{2} )$

B(3,6)

C(9,4)

m = [(3+9)/2 , (6+4)/2]

= (6,5)

M(5,9)

H(8,9)

G(x,y)

[(x+8)/2 , (y+9)/2]=(5,9)

(x+8)/2 = 5

x+8 = 10

x = 2

(y+9)/2 = 9

y+9 = 18

y = 9

G(2,9)
