The probability of rolling a 6 on the 1st roll is
, since there is only 1 out of 6 sides of the dice that has six pips.
The probability of rolling an odd number is
, since there are 3 out of 6 sides of the dice that has an odd number of pips.
Then the probablity of both events happening one after another is
. You have to multiply both probabilities of the events:
Algebra gets much more complicated than that simple equation. This leaves many students WONDERing when, if ever, they’ll use algebra in real life. Does it have any use? If not, why do you have to learn it?
For starters, algebra is foundational for other classes. That means you’ll apply what you learn in algebra throughout school. Learning algebra helps to develop your critical thinking skills. That includes problem solving, logic, patterns, and reasoning. You need to know algebra for many professions, especially those in science and math. Not planning to go into those fields? You’ll probably still use algebra without even realizing it!
Consider these examples: It’s time to fill up your car’s gas tank. The price of gas per gallon is $3 and you only have $25 to spend. How much gas can you purchase? This can be answered by the algebraic equation, “3x = 25.” You must divide each side of the equation by 3 in order to isolate x. In this equation, x is equal to 25 divided by 3, which is 8.33 gallons of gas. If you need 10 gallons of gas, how much money do you need? When you solve that equation, you have algebra to thank!
There are many other examples of real-world uses of algebra, from comparing prices on similar products in a grocery store to figuring out what time you need to leave your house in order to meet a friend across town on time. If you ever WONDER why you need to learn something like algebra, don’t be afraid to ask your teacher or parent (or Wonderopolis!). Odds are, there’s a good reason!
Answer:
Step-by-step explanation:
Slope intercept form: y =mx +c
5x - 2y = 10
-2y = -5x + 10
Answer:
y(x)=12*(5)^x
Step-by-step explanation:
y=ab^x, y(0)=12. 12=a.
y=12*b^x, y(2)=300. 12*b^2=300. b^2=25. b=5
Answer:
y = 4 x - 7
The slope is the number multiplied by x, 4
