Answer:
-4
Step-by-step explanation:
Answer: 0.26
Step-by-step explanation:
As per given , we have
P(green tail) = 0.36
P(red fins) = 0.59
P(both a green tail and red fins ) = 0.21
Now, P(Neither red fin nor green tail )= 1 - P(either red fin or green tail )
<em>[P(neither A nor B)= 1- P(either A or B)]</em>
= 1-(P(green tail) +P(red fins)+P(both a green tail and red fins ))
<em>[P(A or B)= P(A)+P(B)-P(A and B)]</em>
= 1- (0.36+0.59-0.21)
= 1-(0.74)
= 0.26
Hence, the probability that the selected fish will not have a red fin or a green tail = 0.26
5sin(x)=-3cos(x)
sin(x)=-3/5 cos(x)
tan(x)=-3/5
x = arctan(-3/5)
A) 1.05 and 9/10
B) 3/5 and 0.7

<em><u>≡ We know that:</u></em>
↔ y = 4x + 6
⇔ 3x + y = 41
↔ y = 41 - 3x
<u><em>≡ Solution:</em></u>
<em>⇔ First, find the value of x:</em>
⇒ y = y
⇒ 4x + 6 = 41 - 3x
⇒ 4x + 3x = 41 - 6
⇒ 7x = 35
<u>⇒ x = 5</u>
<em>⇔ Then, find the value of y:</em>
⇒ y = 4x + 6
⇒ y = 4(5) + 6
⇒ y = 20 + 6
<u>⇒ y = 26</u>
<em>∴ So, the solution of that equation is (5, 26)</em>
