30% of the sampled students <u>have three or more siblings</u> at home.

<u>Step-by-step explanation</u>:

<u>step 1</u> : The total number of students sampled = 20 students.

<u>step 2</u> : The students having three or more siblings = 6 students.

The question asks for what percentage of the sampled students have three or more siblings.

<u>step 3</u> : Let the unknown percentage be X%

X% of total sampled student = students having 3 or more siblings

(X/100) \times 20 = 6 students.

2x = 6\times10

x = \frac{60}{2}

x = 30 %

WILL GIVE 10 POINTS Leona was using an eyedropper to place droplets in a small container.
il63 [147K]

Answer:

A. milliliters     B. 8 fluid ounces

Step-by-step explanation:

An eyedropper is very small and can only hold a small amount.  You can eliminate 2 from the start: millimeter and meter.  These two are use for measuring distance not volume.  ex.) I walked 2 meters.  A liter is too big for an eyedropper.  ex.) 1 liter of soda.

A glass full of juice would be 8 fuild ounces because a glass is basically a cup.  A 8 gallons is too big, and a 8 tablespoons is too small.  ex.) gallon of milk and tablespoon of sugar.  8 cups is too big because a glass is about 1 cup.  8 fluid ounces = 1 cup

C. Line m is a perpendicular<br> bisector. If EG=12 and FG=5,<br> of then how long is:
strojnjashka [21]

Answer:

EF = 13

GH = 5

EH = 13

Step-by-step explanation:

Given

The attached figure

EG = 12

FG = 5

Solving (a): EF

Since m is a perpendicular bisector, then <EGF and <EGH are right-angled.

So, EF will be calculated using Pythagoras theorem which states:

EF^2 = EG^2 + FG^2

EF^2 = 12^2 + 5^2

EF^2 = 144 + 25

EF^2 = 169

Take the positive square roots of both sides

EF = \sqrt{169

EF = 13

Solving (b): GH

Since m is a perpendicular bisector, then GH = FG

FG = 5

GH = FG

GH = 5

Solving (c): EH

Since m is a perpendicular bisector, then EH = EF

EF = 13

EH = EF

EH = 13

REALLY NEED HELP TIMED TEST!!!!!
Umnica [9.8K]

Answer:

a)13x+3

b) -3x-13

c)4x^2-24

d)-3x^2 +3x

Step-by-step explanation:

a) combine like terms

5x-3+8x+6 so combine the -3 and +6 and 5x and 8x

So 13x+3

b)There is an invisible one in front of (2x-5) and an invisible -1 in front of (5x+8). Distribute these.

2x -5 - 5x -8

So -3x-13

c) Distribute the four to everything in the brackets.

4(x^2-6) becomes 4x^2-24

d) Distribute:

-3x (x-1) becomes -3x^2 +3x
