irina [24]3 years ago

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 gift box in the shape of a rectangular prism measures 8 inches by 8 inches by 10 inches what is the least amount of wrapping p
Phantasy [73]
The first thing we must do for this case is to find the surface area of the rectangular prism.
 We have then:
 A = 2 * (l * h) + 2 * (h * w) + 2 * (w * l)
 Where,
 w: width
 l: long
 h: height
 Substituting values we have:
 A = 2 * (10 * 8) + 2 * (8 * 8) + 2 * (8 * 10)
 A = 448 in ^ 2
 Answer:
 
the least amount of wrapping paper needed to wrap the gift box answer is:
 
A = 448 in ^ 2

10 POINTS! PLEASE HELP!! The illustration shows a compact disc tray that holds five CDs. The radius of each compact disc is 9 cm
MariettaO [177]

We can see that there are 5 CDs, each of radius 9 cm

<u>Area occupied by 1 disc:</u>

Area of a circle = πr²

Area of disc = π(9)²

Area of disc = 3.14 * 81 = 254 cm²

<u>Area occupied by 5 discs:</u>

Area occupied by 5 discs = Area occupied by 1 disc * 5

Area occupied by 5 discs = 254 * 5

Area occupied by 5 discs = 1270 cm²

This one is a tough one. If you can explain it to me that’ll me great.
Crazy boy [7]

Answer:

C. 73 if I have read the given angle measurements correctly.

The angle measurements I see are:

219^\circ

(x-50)^\circ

(x+45)^\circ.

Step-by-step explanation:

Those angles together form a full rotation. A full rotation is equal to 360 degrees.

So we have the following equation to solve:

219+(x-50)+(x+45)=360

Combine like terms:

(x+x)+(219-50+45)=360

Simplify:

2x+(219-5)=360

2x+214=360

Divide both sides be 2:

x+107=180

Subtract 107 on both sides:

x=180-107

x=73
