The probability that all marbles are yellow is
(7/20) (7/20) (7/20) = 343/8000
We are given
x = 2 and 3
u = 2.5
s = 0.5
Getting the z score
z = (2 - 2.5) / 0.5 and (3 - 2.5)/ 0.5
z = -1 and 1
The percentage is
1 - 0.1557 = 81.5%
Answer:
Solved for n, <em>n = 2p</em>
Step-by-step explanation:
14n + 6p - 8n = 18p
6n + 6p = 18p
6n = 12p
n = 2p
Answer:
65°
Step-by-step explanation:
From the figure we can see a circle.
It is given that, measure of arc AD = 80° therefore m<ACD = 80/2 = 40°
Also m<D = 75°
<u>To find the measure of <DCQ</u>
We know that, an angle made by a tangent and chord is equal to the angle made by the angle made by the chord on other side of the circle.
Here m<DCQ = m<CAD
By using angle sum property,
m<CAD + m<ACD + m<D = 180
m<CAD + 40 + 75 = 180
m<CAD + 115 = 180
m<CAD = 180 - 115 = 65°
Therefore m<DCQ = m< CAD = 65°
The correct answer is third option.
We can round numbers to estimate.
337 is approximately 340.
103 is approximately 100.
340 - 100 = 240
John needs to save around $240 more in order to be able to afford the bike.
Hope this helps!
So it's asking you to create an expression on how much you spent.
So you have already spent $30 on a DVD and $20 for a CD. And we don't know how much the videos are so that is x.
Your equation is going to be something like 30+20+5x but since it says it wants it in simplest form it's going to be 50+5x or 5x+50 either way that will be your equation answer. The reason it's that equation is because we know how much you spent already which is 50 and since you bought 5 videos of an unknown number that's how you get 5x.
50+5x
