Help out please thank you
Helga [31]

Answer:

x = 26

Step-by-step explanation:

The three angles form a straight line, so they will sum to 180

4x - 8  + 34  + 76- x = 180

Combine like terms

3x+ 102 = 180

Subtract 102 from each side

3x+102-102 = 180-102

3x= 78

Divide each side by 3

3x/3 = 78/3

x = 26

Applicants who wish to be admitted to a certain professional school in a large university are required to take a screening test
Elden [556K]

Answer:

Probability of eligible applicants who pass the exam is 0.665

probability of applicants who are ineligible but pass the exam 0.063

Step-by-step explanation:

Total percentage eligible applicants who pass the exam

\textrm {89\%  of 70\%}= \dfrac{89\times70}{100}=62.3\%

Total  ineligible applicants  who pass the exam

\textrm {14\%  of 30\%}= \dfrac{14\times30}{100}=4.2\%

All applicants who pass this exam 62.3% + 4.2% = 66.5%

Probability of applicants who pass the exam

\textrm{probability }= \dfrac{66.5}{100}=0.665

Out of 66.5% applicants who pass the exam , 4.2% applicants are ineligible

\textrm{so the probability is}\dfrac{4.2}{66.5}=0.063

Probability of applicants who pass the exam is 0.665

probability of applicants who are ineligible but pass the exam 0.063
