Answer:

Q4 = 4 || Q5 = 6 2/3 || Q6 = 4 4/7 || Q7 = 10 || Q8 = 3 1/3 || Q9 = 4 1/2

Step-by-step explanation:

In order to divide fractions, you just have to turn it into multiplying!
Flip the second fraction in the number sentence and then multiply!

Example: 5 divided by 6/7

Keep 5 as it is. Flip 6/7 to 7/6. 5 x 7/6 = 35/6

Now, simplify it! Simplifying is very simple. You just have to divide until they can't be divided anymore.

35/6 simplified = 5 5/6.

Reason:

How many 6's are in 35? 5 R: 5

So, then it would be 5 5/6.

Hope this helped and this was correct! If you have any more questions, I'll be here to answer them!

Suppose a class of 50 students has 20 males and 30 females. The insturctor will pick 1 (different) student to compete in 3 diffe
Pie

Answer:

Step-by-step explanation:

Total = 50

Males = 20

Females = 30

a) P(exactly 1 female) = P(1 female , 2 male)

(30C1 * 20C2) / (50C3) = 30*190/19,600 = 0.2908

b) P(at least 2 males) = 1 - (P(0 males) + P(1 males))

= 1 - 30C3 * 20C0/50C3 - 30C2 * 20C1/50C3

= 1 - 4060*1/19,600 - 435*20/19,600 = 6840/19600 = 0.3489

The coordinates of A and B are (3k, 8) and (k, -3) respectively. Given that the gradient of the line segment AB is 3, find the v
Vladimir [108]

Step-by-step explanation:

gradient = slope or several other words.

it describes how strongly a line (or tangent to a bent curve) is going up or down or ... if it is changing at all.

it is represented by the ratio

(y coordinate change / x coordinate change)

when going from one point on the line to another.

in our case, when going from A to B we have

x changes by -2k (from 3k to k).

y changes by -11 (from 8 to -3).

so, the gradient or slope is

-11/-2k = 3

11/2k = 3

11 = 3×2k = 6k

k = 11/6

A = (33/6, 8) = (11/2, 8)

B = (11/6, -3)
