Answer:

305

Step-by-step explanation:

If she is at day 19, that means you have to multiply 15 (phones repaired each day) times 19 (19th day) in order to get how many phones she has counted which is 285. To find how much she has left, you have to subtract 285 from 590 which gets you 305.

Christine has always been weak in mathematics. Based on her performance prior to the final exam in Calculus, there is a 40% chan

Answer:

There are a 25% probability that Christine fails the course.

Step-by-step explanation:

We have these following probabilities:

A 50% probability that Christine finds a tutor.

With a tutor, she has a 10% probability of failling.

A 50% probability that Christine does not find a tutor.

Without a tutor, she has a 40% probability of failing.

Probability that she fails:

10% of 50%(fail with a tutor) plus 40% of 50%(fail without a tutor). So

$P = 0.1*0.5 + 0.4*0.5 = 0.25$

There are a 25% probability that Christine fails the course.

How do I solve this equation quick with an easy method?

Pani-rosa [81]

Answer:

4/(3(x-2))

Step-by-step explanation:

3x^2-21x+30=3(x^2-7x+10)=3(x-5)(x-2)

3x-15=3(x-5)

----------------------------

So the common denominator must be 3(x-5)(x-2)

2(x-2)=2x-4

Add the numerators,

(2x-16)+(2x-4)=4x-16-4=4x-20

-----------------

(4x-20)/[3(x-5)(x-2)]

simplify 4x-20 into 4(x-5)

cancel out the (x-5)'s for both the denominator and the numerator

4/[3(x-2)]
