Answer:

4:5 or 0.8

Step-by-step explanation:

if the correspond sides are 24 (smaller figure) and 30 (larger figure), then the requred scale factor is:

24:30=4:5 (or 0,8).

Answer:

-2/3 = -4/6 = -6/9 = -8/12

= -10/15 = -12/18 = -14/21 = -16/24

= -18/27 = -20/30 = -22/33 = -24/36

= -26/39 = -28/42 = -30/45 = -32/48

= -34/51 = -36/54 = -38/57 = -40/60

= -42/63 = -44/66 = -46/69 = -48/72

= -50/75 = -52/78 = -54/81 = -56/84

= -58/87 = -60/90 = -62/93 = -64/96

= -66/99 = -68/102 = -70/105 = -72/108

= -74/111 = -76/114 = -78/117 = -80/120

= -82/123 = -84/126 = -86/129 = -88/132

= -90/135 = -92/138 = -94/141 = -96/144

= -98/147 = -100/150 = -102/153 = -104/156

= -106/159 = -108/162 = -110/165 = -112/168

= -114/171 = -116/174 = -118/177 = -120/180

= -122/183 = -124/186 = -126/189 = -128/192

= -130/195 = -132/198 = -134/201 = -136/204

= -138/207 = -140/210 = -142/213 = -144/216

= -146/219 = -148/222 = -150/225 = -152/228

= -154/231 = -156/234 = -158/237 = -160/240

= -162/243 = -164/246 = -166/249 = -168/252

= -170/255 = -172/258 = -174/261 = -176/264

= -178/267 = -180/270 = -182/273 = -184/276

= -186/279 = -188/282 = -190/285 = -192/288

= -194/291 = -196/294 = -198/297 = -200/300

Step-by-step explanation:

Answer:

1. ACB, CDB and ADC are all similar to eachother.

2. 10

3. CD=8, AD=10.666667, AC=13.33333

4. X=2.4

5. X=√10

6. X=√15

Step-by-step explanation:

1. To prove triangles are similar, prove they share at least two angles.

Triangle ACB is similar to triangle CDB because they both share a 90° angle and ∠B.

Triangle ACB is similar to triangle ADC because they both share a 90° angle and ∠A.

Since ACB is similar to both CDB and ADC respectively, CDB is similar to ADC.

2. Use similar triangles to find AB

ACB is similar to CDB

AB/CB=CB/DB

AB/10=10/6

AB=100/6=16.666667

Geometric mean: √(16.66667*6)=10

3.

Find CD using Pythagorus:

10²=6²+CD²

CD²=100-36

CD=√64=8

Use similar triangle ratios to find AD:

CDB is similar to ADC.

CD/DB=AD/DC

8/6=AD/8

AD=8(8/6)=10.6666666667

Find AC using Pythagorus:

AC²=10.66666666667²+8²

AC=√177.7777777778

AC=13.333333333

4. √(40²+30²)=50

30/50=X/40

X=2.4

5. (√35)²=X²+5²

35=X²+25

X=√10

6. √((√10)²-(√6)²=√(10-6)=2

√6/2=X/√10

6/4=X²/10

X²=10(1.5)

X=√15

Answer:

8 ft 8 in

Step-by-step explanation:

104/12 = 8.666...

This shows that there are 8 total feet because there are 12 inches in a foot

Then, multiply 8*12 to get 96 in order to get the remainder of the inches left that do not make up one whole foot.

Then subtract 96 from 104 (104-96) to get the remainder which is 8 inches.

[character limit thing]

Answer:  0.6274

Step-by-step explanation:

Given: The proportion of patients experience injection-site reactions with the current needle : p=0.11

Sample size : n= 4

Let x be a binomial random variable that represents the people get an injection-site reaction.

Binomial probability formula: [tex]P(X=x)= ^nC_x p^x(1-p)^{n-x}[/tex]

The required probability : P(x=0)

[tex]=\ ^4C_0(0.11)^0(1-0.11)^4\\\\=(1)(1)(0.89)^4\\\\=0.62742241\\\approx0.6274[/tex]

Hence, the  probability that none of the 4 people get an injection-site reaction =  0.6274

The probability that none of the 4 people get an injection-site reaction would be 0.6274.

Binomial distributions consists of n independent Bernoulli trials.

Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Suppose we have random variable X pertaining to binomial distribution with parameters n and p, then it is written as

[tex]X \sim B(n,p)[/tex]

The probability that out of n trials, there'd be x successes is given by

[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]

A medical device company knows that 11% of patients experience injection-site reactions with the current needle.

If 4 people receive injections with this type of needle.

The proportion of patients who experience injection-site reactions with the current needle

p=0.11

Sample size : n= 4

Let a binomial random variable be x that represents the people who get an injection-site reaction.

Binomial probability formula:

P(X = x) = [tex]^nC_x p^x(1-p)^{n-x}[/tex]

The required probability :

P(x=0)

[tex]=\ ^4C_0(0.11)^0(1-0.11)^4\\\\=(1)(1)(0.89)^4\\\\=0.62742241\\\\\approx0.6274[/tex]

Hence, the probability that none of the 4 people get an injection-site reaction would be 0.6274.
