The square root of 10 because
sqrt(10) ^2 * 3.14 =
10*3.14 = 31.4
The answer is 240.5 hope you get the question
For a box and whispers plot, each section represents 25% of the data. Therefore, the area from 85-99 represents 25% of the data.
25% of 24 students= 6 students
Final answer: 6 students
To solve this problem, let us break this down one by one.
There are 20 possible
horses that could win in first place. Therefore this means that for each of
these possibilities, there are now 19 horses that could come in second. So
meaning there are 20 x 19 possible combinations for the first 2 places. <span>
20 x 19 = 380. And for each of those combinations, there are also
18 possible horses that could come in the third place. So </span>
20 x 19 x 18 = 6,840 <span>
<span>There are 6,840 possible horse combinations for the first 3
places in the race. </span></span>
Answer:
see explanation
Step-by-step explanation:
Given
2x² + x - 1 = 2 ( subtract 2 from both sides )
2x² + x - 3 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × - 3 = - 6 and sum = + 1
The factors are - 2 and + 3
Use these factors to split the x- term
2x² - 2x + 3x - 3 = 0 ( factor the first/second and third/fourth terms )
2x(x - 1) + 3(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(2x + 3) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = -
