Step-by-step explanation:

Given equation:

y = 3x – 1

what is the value of y when x equals –3?

Substitute x = -3 into the equation to find y

The probability that someone owns an iPhone is 62%. The probability that someone owns an Apple watch is 15%. The probability som

Dmitry [639]

ANSWER

The probability that someone owns an iPhone or an Apple watch is

$P(I \cup \: A) = 69\%$

or

$P(I \cup \: A) = 0.69$

EXPLANATION

We were given that, the probability that someone owns an iPhone is

$P(I)=62\%$

and the probability that someone owns Apple watch is

$P(A)=15\%$

and the probability that someone owns both is

$P(I \cap \: A) = 8\%$
Since the intersection is not zero, it means the two events are not mutually exclusive.

The probability that someone owns an iPhone or Apple phone is

$P(I \cup \: A) = P(I) + P(A) - P(I \cap \: A)$

We substitute the values to get,

$P(I \cup \: A) = 62\% + 15\% - 8\%$

$P(I \cup \: A) = 69\%$

Increase 20 by 30%<br><br> How do you find the answer??<br><br> Thank you :)

lora16 [44]

The answer is 26. You do: 20*3/10 or 20*0.3 and you get the answer 6. Since the question told u to increase 20 by 30%, you add the six on the 20. 20+6=26
