Need help with a few geometry questions !?!?
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

to get percent of a number just multiply the percent in decimal form by the number for example 8% --> .08
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, what is the probability that none of the 4 people get an injection-site reaction? 0.0001 0.3726 0.4400 0.6274
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.
How to find that a given condition can be modelled by binomial distribution?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.

a street sign is 104 inches tall. How tall is it in feet and inches.
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.
