Answer:

1665

Step-by-step explanation:

This is AP, where:

  • First term is: 12= 3*4
  • Last term is: 99= 3*33
  • Common difference is: 3
  • Number of terms is: 33- 3= 30 (because the 4th term is included)
  • S=1/2*30(12+99)= 1665

The sum of all two - digit natural numbers which are divisible by 3 is 1665

Suppose that 62 percent of the graduates from your high school go on to four-year colleges, 15 percent go on to two-year college
inn [45]

Answer:

b) .474

Step-by-step explanation:

If 62% go to a four-year college, that means that those who don't represent 38% of the high-school graduates.

You pick up someone who is NOT going to a four-year college (so, he's among the 38%)... what's the chance he's in the 18% of the whole high-school graduates population that found a job?

To calculate that probability, we have to divide 18% by 38%.

P = 18% / 38% = 0.4736, so 0.474

Since we are sure he doesn't go to a four-year college, there's 47.4% of chances he finds a job.

wolverine [178]

Answer:

Edible fruit amount is 4.8 ounce to 5.6 ounce  

Step-by-step explanation:

Given as

The seed and skin of avocados is about 30%-40%

And the weight of avocados is 8 ounce

So, the weight of seed and skin is about 30% of 8 to 40% of 8

i.e 2.4 ounce to 3.2 ounce

Then the edible fruit is about 60% to 70%

i.e 60% of 8 to 70% of 8

Thus edible fruit of avocados = 4.8 ounce to 5.6 ounce   Answer
