Q1. 2 headbands are solid, 3 are patterned, and 5 are miscellaneous
so Ms. jones has a probability of 3/10 or 30% chance of picking a patterned headband and because she replaced it she has a 80% chance of not picking a solid headband. 
Q2. 114 because the cumulative frequency or in other words the sum of the frequency up to that point is 138 so you would take that and subtract 24 because thats how many students did not log in more than six times. This give you your answer which is that 114 students logged in more than six times.

5 1/3 + x = 2 1/2. Use least common denominator or easiest common denominator. Please work out
julia-pushkina [17]

Answer:

The answer is x = -17/6.

Step-by-step explanation:

Given:

5 1/3 + x = 2 1/2 . Using least common denominator.

Now, to solve the equation:

5\frac{1}{3}+x=2\frac{1}{2}

=\frac{16}{3} +x=\frac{5}{2}

Subtracting both sides from 16/3 we get:

x=\frac{5}{2}- \frac{16}{3}

Now, the least common denominator of 2 and 3 is 6.

So, we using this we calculate:

x=\frac{5\times 3-16\times 2}{6}

x=\frac{15-32}{6}

x=\frac{-17}{6}

Therefore, the answer is x = -17/6.

Answer:

  (a) Micah's solution is wrong.

Step-by-step explanation:

After adding 5/2x to both sides, Micah should have obtained ...

  5/6 = 8

This would indicate there are no values of x that make the statement true.

Need help..thanks......

Answer: D) Flat area with a large number of plants

The roots of the plants hold in the soil, which prevents/reduces erosion.

The steeper slope means gravity pulls down the soil material faster, since there is less ground in the way to hold it up, so to speak. So flatter areas are less prone to erosion compared to steeper areas.

So that's why overall, flatter areas with lots of plants would have the least erosion.
