Answer:
Follows are the solution to the given points:
Step-by-step explanation:
Given values:
[tex]P(\frac{D}{A})=0.02 \\\\P(\frac{D}{B})=0.01\\\\P(A)=\frac{10,000}{10,000+2000} =\frac{10}{12} =\frac{5}{6} \\\\P(B)=\frac{1}{6}\\\\[/tex]
For point a:
[tex]P(D) =p(D\cap A) +P(D \cap B)\\\\[/tex]
[tex]=P(\frac{D}{A}) \times P(A) + P(\frac{D}{B}) \times P(B)\\\\=0.02 \times \frac{5}{6} + 0.01 \times \frac{1}{6}\\\\=\frac{0.1}{6} + \frac{0.01}{6}\\\\=\frac{0.1+0.01}{6} \\\\=\frac{0.11}{6} \\\\=\frac{11}{600} \\\\=0.0183[/tex]
For point b:
[tex]P(\frac{A}{D})= \frac{P(\frac{D}{A}) \times P(A)}{P(D)}\\\\[/tex]
[tex]= \frac{0.02 \times \frac{5}{6}}{\frac{11}{600}}\\\\= \frac{0.02 \times \frac{5}{6}}{0.0183333333}\\\\= \frac{0.02 \times 0.833333333}{0.0183333333}\\\\= \frac{0.0166666667}{0.018}\\\\=0.9090 \approx 0.0991[/tex]
For point c:
[tex]P(\frac{A}{D^C})=\frac{P(\frac{D^c}{A}) \times P(A)}{P(D^c)}\\\\[/tex]
[tex]= \frac{1-0.02 \times \frac{5}{6}}{1- \frac{11}{600}}\\\\= \frac{0.98 \times \frac{5}{6}}{0.98}\\\\=\frac{5}{6}\\\\=0.833[/tex]

Hence, It make a proportion.
(B) 5/15 and 4/12
5 / 15 = 1 / 3
4 /12 = 1 / 3
Hence, It make a proportion.
(C) 4/12 and 6/24
4/12 = 1/3
6/24 = 1/4
Hence, It don't make a proportion.

6x - 5 + 7x = 34 find variable
Answers
Answer:
x = 3
Step-by-step explanation:
6x - 5 + 7x = 34
Find x
______________
To solve this, we need to isolate x :
First add like terms :
6x + 7x
13x
13x - 5 = 34
Add 5 to both sides :
13x = 39
Divide 13 from both sides to get x alone :
x = 3
Answer:
x=3
Step-by-step explanation:
Start by moving the 5 over creating 6x+7x=34+5. Then add them together 13x=39. And now simplify x=3

Which statement is true about mixing red and yellow paint?
A. using 1 can of red paint and 2 cans of yellow paint would make the same shade of
orange as Rico's mix.
B. Using 6 cans of red paint and 9 cans of yellow paint would make a shade of orange
more red than Rico's mix.
C. Using 4 cans of red paint and 5 cans of yellow paint would make a shade of orange
more yellow than Rico's mix.
D. Using 6 cans of red paint and 8 cans of yellow paint would make a shade or orange
more red than Rico's mix.
Answers
Answer:
D would be the correct answer
Step-by-step explanation:
Rico's orange is 2/3
A's orange is 1/2, which is not the same color.
B's orange is 6/9, which simplifies to 2/3. This would be the same as Rico's, not a shade redder.
C's orange is 4/5. When comparing them equally, C's orange is 12/15, and Rico's is 10/15. C's orange would be redder than Rico's, not yellower.
D is correct because when comparing the two, 6/9, Rico's orange, has more yellow paint than 6/8. Therefore D's orange would have more red than Rico's orange.

Answers
Required table is attached below :
Answer:
0.56
Step-by-step explanation:
Since they both have :
SAT score is the same ; quality of letter is the same ;
High school GPA is 1.5 points higher ;
Therefore, to determine how much Mary's GPA will be higher than Karen's :
Multiply the number of points by the Coefficient of high school GPA Given in the regression table attached below :
High school GPA Coefficient = 0.37635
Number of points = 1.5
= 1.5 * 0.37635
= 0.564525
= 0.56
