Answer:
C) 4
Step-by-step explanation:
Given equation:
The above equation represents proportional relationship.
To find the constant of proportionality.
Solution:
<em>The equation representing proportional relationship is given by:</em>
<em></em>
<em>where represents constant of proportionality.</em>
So, in order to find the value of for the given proportionality relationship, we will solve for
We have:
Solving for
Dividing both sides by 2.
∴
Thus, the constant of proportionality = 4.
Answer:
b.
It's too short. Write at least 20 characters to explain it well
When you roll two numbers you have four kinds of outcomes: EE, EO, OE, OO (where E = even, O = odd).
You get an even sum only if you sum two numbers that are both even or both odd, therefore the outcomes wanted are two: EE and OO.
Therefore:
P(sum is even) = 2 / 4 = 0.5
Hence, there is a 50% probability that, when you roll two numbers, their sum will be even.
3/4 of 120
=3/4*120
=360/4
=90
3/8 of 160
=3/8*160
=480/8
=60
EXPLANATION
The consecutive even numbers are
EXPLANATION
Let
be the first even number then, the next even number will be,
The difference of one-half the larger one and two-fifth the smaller one is 38 gives the equation,
We multiply through with an LCM of 10 to get,
This simplifies to,
We expand the brackets to get,
We group like terms to get,
This simplifies to
Therefore the next even number is is
