Answer:
(2x+1)(x+3)
Step-by-step explanation:
Not much explaining for that...
Part (a)
There are 7 red out of 7+3 = 10 total
<h3>Answer: 7/10</h3>
==========================================================
Part (b)
We have 3 green out of 10 total
<h3>Answer: 3/10</h3>
==========================================================
Part (c)
3/10 is the probability of getting green on any selection. This is because we put the first selection back (or it is replaced with an identical copy)
So (3/10)*(3/10) = 9/100 is the probability of getting two green in a row.
<h3>Answer: 9/100</h3>
==========================================================
Part (d)
Similar to part (c) we have 7/10 as the probability of getting red on each independent selection.
(7/10)*(7/10) = 49/100
<h3>Answer: 49/100</h3>
==========================================================
Part (e)
7/10 is the probability of getting red and 3/10 is the probability of getting green. Each selection is independent of any others.
(7/10)*(3/10) = 21/100
<h3>Answer: 21/100</h3>
==========================================================
Part (f)
We have the exact same set up as part (e). Notice how (7/10)*(3/10) is the same as (3/10)*(7/10).
<h3>Answer: 21/100</h3>
Answer:
To convert an angle measure to radians, multiply it by pi/180.
Step-by-step explanation:
310 * pi/180 = 31pi/18 = 5.41 rad
Answer:
Step-by-step explanation:
m∠2 = 52° [Alternate interior angles]
m∠1 + m∠2 = 180° [Linear pair of angles are supplementary]
m∠1 = 180° - 52°
m∠1 = 128°
m∠3 = 47° [Alternate interior angles]
m∠5 + 52° + 47° = 180° [Sum of linear angles is 180°]
m∠5 = 180° - 99°
= 81°
m∠4 + 47° = 180° [Sum of consecutive interior angles is 180°]
m∠4 = 180° - 47°
m∠4 = 137°
Start by multiplying 1.2 and 7.5 which will give you 9.Then you have 9-8/4. so then you do 8 divided by 4 which is 2. so you have 9-2 and that equals 7.
