Answer:
t = 0, t = - 2
Step-by-step explanation:
Given
- t² - 2t = 0 ← factor out t from each term
t(- t - 2) = 0 ← in standard form
Equate each factor to zero and solve for t
t = 0
- t - 2 = 0 ( add 2 to both sides )
- t = 2 ( multiply both sides by - 1 )
t = - 2, thus
solutions are t= 0, t = - 2
Answer:
The sample size is not appropriate.
The population isn’t given to be approximately normal. And for the following question, "A convenience sample of forty people is taken from a population. Which of the following is a reason why you can not make a statistical inference on the population?" The answer is The wrong sampling method was used.
Miley travel from home to school to work and back home again in 60 different ways
<em><u>Solution:</u></em>
<em><u>Miley walks to school by 1 of 3 routes in the morning</u></em>
So she chooses 1 route from 3 routes
Number of ways = 1 x 3 = 3 ways
<em><u>After school she chooses from 4 different routes to get to work</u></em>
So she has 4 different routes and she picks up 1
Number of ways = 1 x 4 = 4 ways
<em><u>When work is done she travels home by 1 of 5 different ways</u></em>
So she has 5 different routes and she picks up 1
Number of ways = 1 x 5 = 5 ways
<em><u>How many different routes can Miley travel from home to school to work and back home again?</u></em>
Total number of different ways = 3 ways x 4 ways x 5 ways
Total number of different ways = 3 x 4 x 5 = 60 ways
Thus Miley travel from home to school to work and back home again in 60 ways
"the original price of a skateboard was reduced by $15. the new price is $49."
B. p-15=49
Answer:
answer maybe x^2 + 3x - 28
explanation
first of all this is how any number of such a kind shud be written
ax^2 + bx + c
so that rearrange it
7x^2 + 3x -4
but I personally would go further to put it like this
x^2 + 3x - 28
both answers are the same so but maybe one is more considered since ur qn requires standard form
in case of any misunderstanding plizzz reach out for further explanation
hope this helps
