Answer:

For number 1 the answer should be independent.

For number 2 the answer should be independent

And number 3 should also be independent

Step-by-step explanation:

My explanation is that they are all independent because you aren't depending on someone to help you do these things, therefore, independent.

Answer:

x = 7

Step-by-step explanation:

Let

x = the unknown number

double it :

2x

add 11:

2x + 11

I get 25:

The equation is

2x + 11 = 25

2x = 25 - 12

2x = 14

Divide both sides by 2

x = 14/2

x = 7

Answer: 8

Step-by-step explanation:

Pythagorean theorem - a^2+b^2=c^2

a^2+15^2=17^2

a^2+225=289

(subtract 225 from both sides)

a^2=64

(sq root both sides)

a=8

Answer:

D = 3J and D + 20 = 2(J + 20) - 2

Step-by-step explanation:

the first part is obvious. Dad is 3 times as old as his son = D=3J

the second part you're adding 20 years to both Dad and Jim = D + 20 and J+20. now Dad is 2 less than twice Jim's age -> D+20 = 2(J+20)-2

Multiplying both numerator and denominator with same number

Answer:

b

Step-by-step explanation:

The tangent- tangent angle x is half the difference of its intercepted arcs.

Th sum of the arcs in a circle = 360°

major arc = 360° - 90° = 270° , then

x = [tex]\frac{1}{2}[/tex] (270 - 90)° = [tex]\frac{1}{2}[/tex] × 180° = 90° → b

[tex]24 + - 4 \sqrt{2} + 6 \sqrt{2} - 2[/tex]

[tex]22 + 2 \sqrt{2} [/tex]

so 22+2=24

that means the b=22

and c=2

Answer:

See answers below

Step-by-step explanation:

1) The typr of triangle in a semicircle is a right angle. Hence the measure of  m<ABC  is 90degrees

2) m<DEF = 1/2(144)

m<DEF = 144/2

m<DEF = 72degrees

3) From the trinagle

4x+3 + x+7 +90 ==180

5x + 100 = 180

5x = 180-100

5x = 80

x = 80/5

x = 16

<QRD =  x+7

m<QRD = 16 + 7

m<QRD = 23degrees

4)  Angle in the same segment are equal

5x-37= 3x+1

5x - 3x = 1+37

2x = 38

x = 38/2

x =19

arc NM = 2m<P

arc NM = 2(3x+1)

arc NM = 2(3(19)+1)

arc NM = 2(58)

arcNM = 116degrees

Answer:

D

Step-by-step explanation:

since this feels like a sequence, a1 should be the first Expression to the arimethic sequence and the rest should be the (n - 1)d so I think it should be 1/2 + 4(an - 1)

note: arimethic sequence formula is a + (n - 1)d

Answer:

140.6 ft³

Step-by-step explanation:

The volume remaining is calculated as

V = volume of block - volume of cylinder

   = s³ - πr²h ( s is side of block, r is radius, h is height )

Here s = 6, r = 4 ÷ 2 = 2, h = 6 , then

V = 6³ - (π × 2² × 6)

   = 216 - (π × 4 × 6)

   = 216 - 24π

   ≈ 140.6 ft² ( to the nearest tenth )

Answer: 40%

48 cars

Step-by-step explanation:

120 divided b7 15 = 8, 8 times 5 = 48

48/120 is 40%

40% percent of the cars were previously damaged in a accident out of 120 in the lot. Do 120 ÷ 15 then divide that by 6 to get your answer of 40%

The best estimate of the percent of the used-car lot's vehicles that have previously been in an accident is 40%

A Percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100.

It is given that

A used car lot has 120 vehicles for sale. A sample of 15 of these vehicles finds that 6 of them have previously been in an accident.

if in 15 cars 6 of them have been in an accident

then in 120 vehicles = 120*6/15

48 cars have been in an accident

Now the best estimate of the percent of the used-car lot's vehicles that have previously been in an accident.

(48/120 ) *100

= 40%

Therefore the percent of the used-car lot's vehicles that have previously been in an accident is 40% .
