Answer:
Option C is correct
P(A or B) = 0.65
Step-by-step explanation:
<u>Given:
</u>
P(A) =0.5
P(B)=0.30
P(A and B) =0.15
( The probability of the happening of both independent events will be there product) P( A and B ) =P(A).P(B)
<u>Solution:</u>
To find the probability of the Happening of event A either event B we will use the following formula
P(A or B) = P(A) + P(B)-P(A and B)
= 0.5 + 0.3 - 0.15
=0.65
2sin²(-2490)+tan 1410=2sin²(-330-6*360)+tan (330+3*360)=
=2sin²(-330)+tan (330)=2 sin²(30-1*360)+tan (-30)=
=2sin²(30)-tan (30)=2(1/2)²-√3/3=1/2-√3/3)=(3-2√3)/6
Answer: 2 sin²(-2490)+tan (1410)=(3-2√3)/6 (≈-0.07735...)
Answer: $13.95
50%+ of 9.30 is 13.95 (if you do the math)
So he has 4 hrs on his mp3 player...for which jazz makes up 1/6 of it..
so we need 1/6 of 4 hrs...." of " means multiply
1/6 * 4 = 4/6 = 2/3 of an hr <==
If the area of the old garden was 1m^2, then the side lengths were both 1
if she increases the lengths by 50%, then 1 turns into 1.5
1.5 times 1.5 is 2.25
The area of her new garden is 2.25m^2
