Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
Number of flights from New York to California = 6
Number of flights from California to New York = 7
Since if the flights are to be made on separate days,
So, they are independent events.
So, the number of different flight arrangements that can be made offer from New York to Hawaii would be
Hence, Option 'a' is correct.
The solutions for the given equation are x = -1 and x = 3/4. Using the quadratic formula, the solutions for the given equation are calculated.
The formula which is used to calculate the roots(solutions) of the quadratic equation in the form is
x = [- b ± ]/2a
The given equation is
In comparison with the standard form of quadratic equation ,
we get, a = 4, b = 1 and c = -3
So, solving the given equation using the quadratic formula,
x = [- b ± ]/2a
= [- 1 ± ]/2(4)
= [-1 ± ]/8
= (-1 ± 7)/8
Thus, x = (-1 + 7)/8 = 3/4 and x = (-1-7)/8 = -8/8 = -1
Therefore, the solutions of the given equation are x = -1 and x = 3/4.

Answer
Length measured using Ruler A= 1.17 dm
Length measured using Ruler B=1.18 dm
Step by Step Explanation:
I have added the missing photograph which shows the length of pencil being measured with two rulers.
Ruler A has marking separated by 1 dm
Ruler B has marking separated by 0.1 dm
Length measured using Ruler A= 1.17 dm
(As we can see I have added the middle markers, we can see the tip of pencil is somewhere between 1 and 1.25, it is more than 1.125 but lesser than 1.25, it is somewhere around 1.2 and 1.125 dm, approximately equal to one half of 1.25 which is 1.125 with addition of one of the three halves of half of 1.125 which is 1.125+0.045 dm hence 1.17dm)
Length measured using Ruler B=1.18 dm
(we can see the tip of pencil is just before 1.2 dm, it is clear that the value is precisely 1.18 and not 1.19 dm)
<u><em>Tip:Always measure one more decimal than given by the ruler when unsure about the exact value</em></u>
