Help me plz:( <br><br> It’s just 22-24

Marrrta [24]

Answer:

1) 5.9

2) 8.1

3) 54

Step-by-step explanation:

A is opposite, so we have sine 36=a/10

sine 36(10)=a

a=5.9

B is adjacent, so we have cosine 36=b/10

cosine 36(20)=b

b=8.1

Angles of a triangle add to 180

we have a angle of 36 and a right angle which is 90

36+90=126

180-126=54

Three boxes contain red and green balls. Box 1 has 5 red balls* and 5 green balls*, Box 2 has 7 red balls* and 3 green balls* an

SSSSS [86.1K]

Answer: 0.375

Step-by-step explanation:

Let G be the event that the chosen marble is green. Let $B_i$ be the event that we choose Box i.

The probabilities of choosing a box are :

$P(B_1)=\dfrac{1}{40}=0.25\\\\P(B_2)=\dfrac{1}{2}=0.5\\\\P(B_3)=\dfrac{1}{4}=0.25$

Now, $P(G|B_1)=\dfrac{5}{10}=0.5$

$P(G|B_2)=\dfrac{3}{10}=0.3$

$P(G|B_1)=\dfrac{4}{10}=0.4$

By using the law of total probability, we have

$P(G)=P(G|B_1)P(B_1)+P(G|B_2)P(B_2)+P(G|B_3)P(B_3)\\\\\Rightarrow\ P(G)=0.25\cdot0.5+0.5\cdot0.3+0.25\cdot0.4=0.375$
