how would you estimate the sum? just like estimate the fractions and then get your estimated answer? Q: 2 1/6 + 3 6/11

1 answer:

4 0

I think estimation is terrible. If u want to truly solve it, you just need to get a common denominator on each of the fractions. that means the bottom half of both fractions must be the same in addition or subtraction. so here, the common denominator would be 66. What times 6 = 66? 11. So 1*11/6*11 = 11/66. Then what times 11 = 66? 6. So 6*6/6*11. Your new problem is 2 11/66 + 3 36/66. Now you can just add it up, but the denominators will always stay the same, 66. Your answer would be 5 47/66

FrozenT [24]

Answer:

10:17

Step-by-step explanation:

If I am making a ratio of the tickets Cindy sold to the number of tickets sold in all it would be 40:68 but I would have to simplify and 40 divided by 2 = 20 and 68 divided by 2 = 34 then I would divide them both by two again to get our answer of 10:17! Hope this helps! Have a great day!

The air force reports that the distribution of heights of male pilots is approximately normal, with a mean of 72.6 inches and a

Anon25 [30]

Answer:

Step-by-step explanation:

Given that X - the distribution of heights of male pilots is approximately normal, with a mean of 72.6 inches and a standard deviation of 2.7 inches.

Height of male pilot = 74.2 inches

We have to find the percentile

X = 74.2

Corresponding Z score = 74.2-72.6 = 1.6

P(X<174.2) = P(Z<1.6) = 0.5-0.4452=0.0548=5.48%

i.e. only 5% are below him in height.

Thus the malepilot is in 5th percentile.

Given:

$\frac{3x}{4}$

Find: values belong to the solution

Explanation:

$\begin{gathered} \frac{3x}{4}$

and

$\begin{gathered} -\frac{x}{6}\ge-3 \\ -x\ge-18 \\ x\leq18 \end{gathered}$

so those values are solution which is x<12

i.e; x=4 and x=11
