Answer:
$19.50
Step-by-step explanation:
You can set up a simple equation where t-shirts are represented by t and cost by c.
$78=4t.
To solve this equation, you want to get the variable isolated. To do this divide four on both sides since the t is multiplied by 4 and to undo multiplication, you divide. So you divide 4t by four, which gets you 1t, and then you divide 78 by 4 (because whatever you do to one side you have to do it to the other) which gives you 19.5. So the remaining equation is
$19.50=1t
And since t represents t-shirts, the equation is saying that $19.50 is equal to one t-shirt.
Answer:
Independent events are those that do not depend on others. Two entities does not depend on each other. The change in one entity does not change the other.
So, independent events here are-
1. rolling a number cube twice.
2. flipping a coin 4 times.
3. choosing a meal combination.
Rest two options are dependent on each other.
it's not d because it will go over 3 so its c because 15×2/3=10
