Hat is he probability of pick 1 green marble from a bag with 7 green and 8 blue marbles

Mathematics
1 answer:
disa [49]3 years ago
7 0

Answer:

7/15

Step-by-step explanation:

<em>No. of green marbles in the bag= 7</em>

<em>No. of blue marbles in the bag= 8</em>

<em>Total no. of marbles in the bag= 7+8=15</em>

As we know that,

Probability( of a random event A)= \frac{Favourable\ no.\ of\ elementary\ events}{Total\ no.\ of\ elementary\ events}

Hence in this case,

Favourable np. of elementary events (green marbles)=7

Total no. of elementary events (Total no. of marbles in the bag)= 15

Hence, Probability of picking a green marble from the bag=\frac{7}{15}

Simplify by dividing [ -3/-8] divided by 5/9 (5 points)
rewona [7]

Answer: D

Step-by-step explanation:

(3/8) / (5/9) is the same as multiplying (3/8) by (9/5) which is 27/40. I'm not sure if there's an error between C and D because those are both the same answer since dividing a negative number by a negative number gives you a positive number.

I think C was supposed to be -27/40 so D is the correct answer since it's positive.

How to show opposite sides on a parallelogram are congruent
Marta_Voda [28]

Answer:

I am attaching a image to understand my proof.

Step-by-step explanation:

PROVE:-

AB = DC

AD = BC

∠ ABD = ∠ BDC        (alternate angles are equal )

∠ DBC = ∠ ADB         (alternate angles are equal )

∴ Δ ADB ≅ Δ CBD     ( by ASA rule )

DC = BA                       ( corresponding sides of ≅ Δ )

AD = CB                        ( corresponding sides of ≅ Δ )

Hence it is proved that opposite sides of parallelogram are congruent )
