1 answer:
Nonamiya [84]3 years ago

Answer:

c = 4

Step-by-step explanation:

For this triangle we have to

A=63\\C=49\°\\c=3\°

Now we use the sine theorem to find the length of a:

\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}

Then:

\frac{sin(A)}{a}=\frac{sin(C)}{c}\\\\a=\frac{sin(A)}{\frac{sin(C)}{c}}\\\\a=c*\frac{sin(A)}{sin(C)}\\\\a=(3)\frac{sin(63)}{sin(49)}\\\\c=4

About 7​% of the population of a large country is math phobic. If two people are randomly​ selected, what is the probability bot
ss7ja [257]

Answer:

What is the probability both are math phobic​? 0.49%

What is the probability at least one is math phobic​? 9.31%

Step-by-step explanation:

In order to both be math phobic, both individuals has to be inside of the probability of 7%, that means 0.07*0.07 = 0.0049 = 0.49%

In order to at least one be math phobic there's some cases which satisfies the sentence:

Individual A is math phobic and B as well = 0.07*0.07 = 0.0049 = 0.49%

Individual A is math phobic, but B is not = 0.07*0.63 = 0.0441 = 4.41%

Individual A is not, but B is math phobic = 0.63*0.07 = 0.0441 = 4.41%

Suming the 3 possibles cases, the probability at least one is math phobic​

= 9.31%

vodomira [7]

Answer:

40%

Step-by-step explanation: 3 + 5 = 8 boys total   4 + 8 = 12 girls total   8 + 12 = 20 kids total. To find out the probability of randomly choosing a boy you have to do the number of boys over the total amount of kids (8/20) which will equal 40%.
