Answer:
(A) 21
Step-by-step explanation:
5x-15 needs to equal 90 since it is a right angle and 21 makes that true

the difference of 5 times the cube of x cubed and the quotient of 4 times x and 3
5*x^3 - (4x/3)
Probability is the chance of an event occuring. It is obtained by the formula number of outcomes / total number of possible outcomes.
The probability of a blue jay being the next bird papa sees is given by number of blue jays / total number of birds = 59 / (59 + 68 + 12 + 1) = 59 / 140 = 0.4214
Answer:
1020
Step-by-step explanation:
well, the first three significant figures stops at the 102, so round the 1023.4567 to a whole number which just becomes 1023
then, round the answer so you only have the 102, so you would round down since 4 or less, which 3 is less than 4, you round down, and you would get 1020
that last 0 is not a significant figure because it does not have a decimal point or any other number following after it--any 0s at the end of a number are not significant if there is no decimal point or other number after them.
i really don't understand what you are trying to say but if it was a math problem it would be -1.
