Answer:
a) The set of natural numbers greater than or equal to 3 and less than or equal to 6.
b) {3,4,5,6}
Step-by-step explanation:
a) The Roster form is given as {6,8,10,12,...}
The descriptive form is a phrase that describes the given set.
The descriptive form is: <em>The set of even natural numbers greater than or equal to 6.</em>
b) The descriptive form is : The set of natural numbers greater than or equal to 3 and less than or equal to 6.
The Roster form is obtained by listing the numbers between 3 and 6 inclusive in curly brackets.
The Roster form is : {3,4,5,6}
Answer:
6
Step-by-step explanation:
72 multiplied by 6 equals 432
Tricky question. This isn't a ratio question even though it seems like one.
First divide 7 by 4.
With more men, the hours taken to repair a road will be even shorter.
So next divide 6 by 1.75.
Answer : It'll take 3.43 hours to do the job if they work at the same rate.

Answer:
15 3/4t^2 + 5 1/4
Explanation:
h(t)=-16t^2+400
We can add 400 then - 64 and show as 8^2
= h(t)=-16t^2+400 - 8^2
But we also need to change 16t^2;
We divide 64 into 16 = 16/64 =0.25
and show 16t^2 changes by 0.25 = 1/4
15 3/4t^2 + 400-64
Can now look like
15 3/4t^2 + 5 1/4
As 5 1/4 = 64 x 5 1/4 = 336
Answer:
2/10 * 2/10 = 1/25
Step-by-step explanation:
Suppose you have 10 marbles in a bag.
5 black , 2 pink and 3 blue
As if two pink marbles are selected then
for one pink marble
probability = event occurred / total outcomes
= 2/10
Similar probability for an other pink marbles
Probability for the drawing two pink marbles is
P = 2/10 * 2/10
= 1/25
