A math teacher gave her students two tests. On the first test, 80% of the class passed the test, but only 30% of the class passe

zimovet [89]

Answer:

0.375 is answer

Step-by-step explanation:

Given that the math teacher gave her students two tests. On the first test, 80% of the class passed the test. But only 30% of the class passed both tests.

Let A - the students pass I test

B = students pass second test

Then P(A) = 80%=0.8 and P(AB) = 30% =0.30

Required probability =probability that a student passes the second test, given that they passed the first one

= P(B/A) = P(AB)/P(A)

= 0.30/0.80

=3/8

=0.375

Right answer is 0.375

Answer:

Yes, these triangles are congruent

∠E≅∠M

Step-by-step explanation:

Yes, these triangles are similar.

Proof:

Each side in LNM is $1\frac{2}{3}$ times longer than the sides in GFE

$30/18 = 1\frac{2}{3}$

$25/15=1\frac{2}{3}$

$20/12 = 1\frac{2}{3}$

According CPCTC (corresponding parts of congruent triangles are congruent), angle E is similar to angle M.

Hope this helps :)

Have a good day!

Peter’s dog eats 0.3 kilograms of dog food each day. How much dog food will Peter’s dog eat in 8 days?

melisa1 [442]

Peter dog ate 2.4 kilograms of dog food in 8 days

Solution:

Given that peters dog eats 0.3 kilograms of dog food each day

To find: amount of dog food eaten by peter dog in 8 days

From given question,

one day = 0.3 kilograms of food

Let "x" be the amount of dog food eaten by peter dog in 8 days

Then for 8 days:

amount of dog food eaten in 8 days = amount of dog food eaten in 1 day x 8

$x = 0.3 \times 8$

On multiplying we get,

x = 2.4

Thus peter dog ate 2.4 kilograms of dog food in 8 days
