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:
Step-by-step explanation:
Answer:
The correct option is A.
Step-by-step explanation:
The given graph sh a shows scatter plot and linear model of Joanna's height, in inches, for various ages.
From the given graph it is noticed that the linear line passing through the points (0,30) and (2,35).
The slope of the linear model is
The slope of linear model is 2.5, it means the Joanna can expect her height to increase about 2.5 inches every year.
Therefore option A is correct.
Answer:
104 in²
Step-by-step explanation:
If OR = 8 then 8 x 2 = 16
PM= (42-16)/2=13
Therefore area = 8 x 13 = 104 in²
To check the perimeter is right:
2(8+13) = 42
The answer should be 0.5x^4+12.5
