Hi there! The answers are 12, 18 and 30.
When we split up 60 in a ratio of 2:3:5, we must realise that we have 2 + 3 + 5 = 10 parts in total.
One part equals 60 / 10 = 6
2 parts equals (60 / 10) * 2 = 12
3 parts equals (60 / 10) * 3 = 18
5 parts equals (60 / 10) * 5 = 30
Therefore, 60 split up in a ratio of 2:3:5 is 12:18:30. The answers are 12, 18 and 30.
~ Hope this helps you!
Answer:
0.98046
Step-by-step explanation:
Given:
Here we are required to find
P(5.48 <X<5.82) and between 5.48 and 5.82 we each z-score given by
<em>z = (x - μ) / σ</em>
So 5.48 we have z = -2.714 and 5.82 we have z = 2.143
Therefore we have the area of interest on the normal distribution chart given by
:
P( -2,714 < z < 2.143)
= 1 - P(Z<-2.714) + P(Z > 2.143)
= 1 - P(Z<-2.714) + (1 - P(Z < 2.143))
= 1 - 0.00336 + 1 - 0.98382
= 1 - 0.01954 = 0.98046

Yes

They both equal 50%
Answer: D
A good trick to have up your sleeve is to just memorize that the equation of a like is (y - y1) = m * (x - x1).
This equation describes a point that passes through (x1, y1) with a slope m. This point (x1, y1) does not have to be on the y-axis. Also, since the question told us they want m = slope = -1/4, all we have to do is plug stuff in.
(y - y1) = m * (x - x1) => (y - 4) = -1/4 * (x - 4), or answer D. Also note that the normal ‘x’ and ‘y’ here are variables. We can solve this equation for ‘y’ to give a more traditional format: y = -1/4x + 5.
