(40 POINTS!!!!) find FD
Answer:
FD = 25.94
Step-by-step explanation:
13x - 16 = 4x + 11 (Tangents drawn from an external point are equal)
13x - 4x = 11 + 16
9x = 27
x = 3
substituting x in 4x + 11,
4(3) + 11
12 + 11

ΔFED is a right triangle,
FD² = FE² + DE²
FD² = 12² + 23²
FD² = 144 + 529
FD² = 673
FD = 25.94
Answer:
FD= +-25.94
Step-by-step explanation:
EF=CF=r(radius)=12
we know,
FD^2=EF^2+ED^2 ......(1)
and
FD^2=CF^2+CD^2 ......(2)
We Know,
area of triangle, a= 1/2xbasexHeight
a=1/2xEFxED .......(3)
and
a=1/2xCFxCD .....(4)
from equation 3 and 4
1/2xEFxED=1/2xCFxCD
=> 1/2x12xED=1/2x12xCD
=>ED=CD
=>13x-16=4x+11
13x-4x=16+11
9x=27
x=3
so
FD^2=EF^2+(ED)^2
FD^2=(12)^2+(4x3+11)^2
=>FD^2=144+529
=>FD^2=673
FD=+-25.94

I'm very bad in geometry. Sorry mom I failed geometry .
Solve the equation square root of the quantity x plus 3 plus 4 equals 5 for the variable. Show each step of your solution process
Answer:
x=-2
Step-by-step explanation:
[tex]\sqrt{x+3}+4=5[/tex]
subtract 4 from each side
[tex]\sqrt{x+3} +4-4=5-4[/tex]
square both sides
[tex]\sqrt{x+3}^2=1^2[/tex]
so we have
[tex]x+3=1[/tex]
subtract 3 from each side
[tex]x+3-3=1-3[/tex]
so our answer is [tex]x=-2[/tex]
thirty percent of all seventh graders own a bracelet. explain whether the sample closely estimates the percentage of seventh graders who own a bracelet.
30 seventh graders, 3 own a bracelet
The sample of 3 seventh graders who own a bracelet out of 30 seventh graders does not closely estimate the thirty percent of all seventh graders owning bracelets.
What is a percentage?Percentages are fractions where the denominator is 100.
We have,
Number of seven grade students = 30
Number of students who own a bracelet = 3
The percentage of seven grade student who owns a bracelet:
= (3 / 30) x 100
= (1/10) x 100
= 10 %
This means that 10% of seven grade student owns a bracelet.
Thus, the sample does not closely estimate the percentage of seventh graders who owns bracelets.

Quadrilateral ABCD is a parallelogram with < BCA= 50 , < DCA=60, find value of
Answer:
[tex]ADC = 70[/tex]
Step-by-step explanation:
Given
[tex]BCA = 50[/tex]
[tex]DCA = 60[/tex]
See attachment for parallelogram and complete question
Required
Find ADC
From the attachment:
[tex]BCD = BCA + DCA[/tex]
[tex]BCD = 50+60[/tex]
[tex]BCD = 110[/tex]
Adjacent angles add up to 180.
So:
[tex]ADC + BCD = 180[/tex]
[tex]ADC = 180-BCD[/tex]
[tex]ADC = 180-110[/tex]
[tex]ADC = 70[/tex]

A small liberal arts college in the Northeast has 350freshmen. One hundred five of the freshmen are female. Suppose sixty freshmen are randomly selected (without replacement).Step 2 of 2:Find the standard deviation of the number of females in the sample. Round your answer to two decimal places, if necessary.
Answer:
The standard deviation of the number of females in the sample is 3.21.
Step-by-step explanation:
For each freshmen, there are only two possible outcomes. Either it is a female, or it is not. Sixty freshmen are randomly selected (without replacement). This means that the hypergeometric distribution is used to solve this question.
Standard deviation of the hypergeometric distribution:
We have that:
N is the population size.
n is the sample size.
s is the number of successes in the sample.
The standard deviation is given by:
[tex]\sigma = \sqrt{n(\frac{s}{N})(1 - \frac{s}{N})(\frac{N - n}{N-1})}[/tex]
A small liberal arts college in the Northeast has 350freshmen.
This means that [tex]N = 350[/tex]
One hundred five of the freshmen are female.
This means that [tex]s = 105[/tex]
Suppose sixty freshmen are randomly selected
This means that [tex]n = 60[/tex]
Find the standard deviation of the number of females in the sample.
[tex]\sigma = \sqrt{60(\frac{105}{350})(1 - \frac{105}{350})(\frac{350 - 60}{350 -1})} = 3.21[/tex]
The standard deviation of the number of females in the sample is 3.21.

(11+x)/2-(9x-3)/4 x=3
Answer:
(11+X)/2-(9x-3)/4 x=3
subsititute 3 into all x
(11+3)/2-(9*3)-3)/4
first solve the first diviision
2-(9 times 3)-3/4
=2-(27-3)/4
=2-(24)/4
since the "2-" is there, you have to subtract it from 24 before you dividewhich would then be
22/4=5.5(in decimal form)
DON'T forget you have another bracket waiting for you since you were given 3 brackets. bring the first bracket down
2-(9x-3)/4 was solved and we got 5.5, so basically we are "substituting 5.5 into that part of the question)
11+x/5.5
11+3/5.5
14/5.5
=2.54 which is your final answer
Sorry if I went overboard lol.
Step-by-step explanation:
yes, the answer is 2.54 I believe.
