8 weeks?
Step-by-step explanation:
25x8=200
or 200/25=8
Answer:
AB=12 BC=9
Step-by-step explanation:
Any side of a triangle must be shorter than the other two sides added together.
AB and A'B' must measure LESS than the other 2 sides
15 is 3/4 of 20
12 is 3/4 0f 9
20/15 12/9 = 1.3333333........
Answer:
x = - 3 or x = 7
Step-by-step explanation:
Given
f(x) = x² - 4x + 6
If f(x) = 27, then equating gives
x² - 4x + 6 = 27 ( subtract 27 from both sides )
x² - 4x - 21 = 0 ← in standard form
Consider the factors of the constant term ( - 21) which sum to give the coefficient of the x- term ( - 4)
The factors are - 7 and + 3, since
- 7 × 3 = - 21 and - 7 + 3 = - 4, hence
(x - 7)(x + 3) = 0
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 7 = 0 ⇒ x = 7
Step-by-step explanation:
The given data is :
195, 194, 191, 190, 238, and 192
Mean = (sum of observations)/(total no. of observations)
So, the mean is the best measure. Also, w can find median as follows.
arranging in order : 190,191,192, 194, 195,238
Here, n = 6
Hence, this is the required solution
