Answer:

(a) 0.4 or 40%

(b) 0.1 or 10%

Step-by-step explanation:

(a) If you get 4 "ones" after 10 rolls of the die, the proportion of the rolls that resulted in "ones" is:

p=\frac{4}{10}\\ p=0.4

(b) If you get 2 "ones" after 20 rolls of the die, the proportion of the rolls that resulted in "ones" is:

p=\frac{2}{20}\\ p=0.1

Elanso [62]

Answer:

The measure of angle BCD is 68.5\°

Step-by-step explanation:

step 1

Find the value of x

we know that

m -----> form a straight line

substitute the values

(3x+4)\°+(6x-8)\°+(7x-20)\°=180\°

(16x-24)\°=180\°

16x=180\°+24\°

16x=204\°

x=12.75\°

Veronika [31]

Answer: $2,393.42

Step-by-step explanation:

I suppose that the salary is yearly.

So in one year, 365 days, the net pay would be $62,400.

Now, "by-weekly" refers to two weeks or 14 days.

If she gets paid $62,400 in 365 days.

Then in 14 she gets paid.

N = (14/365)*$62,400 = $2,393.42
