Answer: A. only II

Step-by-step explanation:

Mathematics calculus differentiates things into discrete and continuous. Discrete things have indivisible units, the example will be how many dogs in a village. There is no half dog, it's either one, two, etc. But the distance covered by train can be written as half miles, it's the divisible unit.

The number of books and bracelets also discrete, thus the answer is A.

How can you make your answer (41-13i)/(25) into a+bi form?

KengaRu [80]

Hello, do you know that for any a, b and c real numbers with c different from 0 the following is correct?

$\dfrac{a+b}{c}=\dfrac{a}{c}+\dfrac{b}{c}$

Then,

$\dfrac{41-13i}{25}=\dfrac{41}{25}-\dfrac{13}{25}i$

So,

$a=\dfrac{41}{25}\\\\b=\dfrac{-13}{25}$

Thank you.

I really need help with this pls help and show work

ohaa [14]

okay so first we need to multiply 160 on both sides

{18/32(160)=n/160*160 (160 cancels out)}

so once we finish our calculations on the left side we get n equals 90

{n=90}

O A box contains 40 oranges, 12 of which are

konstantin123 [22]

Step-by-step explanation:

Nø of sample space, n(s) = 40

nø of unripe oranges, n (u) = 12

no of ripe oranges, n (r) = 40 - 12 = 28

Now

The probability that it is ripe is, P(E)

= n(r) / n(s)

= 28 / 40

= 7 / 10

Also the probability that it is unripe is, P(E)

= n(u) / n(s)

= 12 / 40

= 3 / 10

Hope it will help :)❤
