If you get this right i’ll give the brainliest answer

horsena [70]

Answer:

$c=108.17$

Step-by-step explanation:

Use Pythagoras theorem to find the hypotenuse:

$c^{2} =a^{2} +b^{2}$

In this question, take "b" as 90' and "a" as 60'

$c^{2} =60^{2} +90^{2}$

$c^{2} =3600+8100$

$c^{2} =11700$

$c=\sqrt{11700}$

$c=108.1665383$

$c=108.17$

Suppose 1% of cotton fabric rolls and 4% of nylon fabric rolls contain flaws. Of the rolls used by a manufacturer, 70% are cotto

Amanda [17]

Answer:

0.019 or 1.9%

Step-by-step explanation:

The probability that a randomly selected roll used by the manufacturer contains flaws is determined by the probability of a flawed cotton roll occurring (1% x 70%) added to the probability of a flawed nylon roll occurring (4% x 30%) .

$P(F) = P(C)*P(F_C)+P(N)*P(F_N)\\P(F) = 0.7*0.01+0.3*0.04\\P(F) = 0.019 = 1.9\%$

The probability that a randomly selected roll contains flaws is 0.019 or 1.9%
