Answer: B
Step-by-step explanation:
An outlier/anomaly is basically a point that doesn't follow the general trend. In this question there is clearly only one point that looks out of place. Therefore there is one outlier
Answer:
light takes 3×10^5 second s
so total seconds taken by the light =780×10^6/3×10^5
1 min=60sec
no. of min=2600/60
=43333min
Answer:
<u><em> 4 • (2a + 3b) • (2a - 3b)</em></u>
Step-by-step explanation:
Step 1 :
Equation at the end of step 1 :
(16 • (a2)) - (22•32b2)
Step 2 :
Equation at the end of step 2 :
24a2 - (22•32b2)
Step 3 :
Step 4 :
Pulling out like terms :
4.1 Pull out like factors :
16a2 - 36b2 = 4 • (4a2 - 9b2)
Trying to factor as a Difference of Squares :
4.2 Factoring: 4a2 - 9b2
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 4 is the square of 2
Check : 9 is the square of 3
Check : a2 is the square of a1
Check : b2 is the square of b1
Factorization is : (2a + 3b) • (2a - 3b)
Final result :
4 • (2a + 3b) • (2a - 3b)
B is the correct answer. you can not multiply the first ratio be anything to make it equal the 2nd.
Answer:
66 centimeters
Step-by-step explanation:
1 meter is 100 centimeters
so if harold is 2 meters tall then hes 200 centimeters tall
henery is 1.34 meters tall so he's 134 centimeters
200-134= 66
