Answer:

Step-by-step explanation:

i^{11}+i^{16}+i^{21}+i^{26}+i^{31}

=(i^{2} )^5i+(i^{2} )^8 +(i^{2} )^{10} i+(i^{2} )^{13}+(i^{2} )^{15} i\\=(-1)^5 i+(-1)^8+(-1)^{10} i+(-1)^{13} +(-1)^{15} i\\=- i+1+i-1-i\\=0- i

I got number 7 wrong can someone help me with the answer and the work
Amiraneli [1.4K]
To figure out this problem break it down into steps.

We know that there are 1 - 25 or 25 cards in total, one card is taken out and not replaced so now there are only 24 cards.

25 - 1 = 24.

Find the probability of getting one number greater than 10, this would be all numbers from 10 - 25, which are 25 - 10 = 15 options to choose that will give you a value greater than 10.

Probability = 15/24 = 5/8.

For 2 cards simply multiply the probability by itself to get 2 cards where the number is greater than 10.

5/8 • 5/8 = 25/64.

The probability of getting 2 cards that are greater than 10, are 25/64.

This is the solution.

Answer:

$87.50

Step-by-step explanation:

first minus the number of minutes he doesn't have to pay

400 - 150 = 250

then times the number of leftover minutes by how much it costs a minute ($.35 because 35¢ is equal to $.35)

250 × $.35 = $87.50

that's how much.
