<em>1 yard = 3 feet </em>. That's a definition of a yard.
You need to know it, in order to answer this question.
2 yards = 6 feet
3 yards = 9 feet
4 yards = 12 feet
<em>5 yards = 15 feet</em>
6 yards = 18 feet
.
.
etc.
Let the variable of the equation be x.
I'm gonna go backwards of the factorization process.
Given,
x = 11 or 3
(x - 11)(x - 3) = 0
x² -3x -11x + 33 = 0
x² -14x + 33 = 0
Hence, f(x) = x² - 14x + 33.
3/4 of the way is:
540 miles* (3/4)= 405 miles.
405 miles* (1 hour/ 45 miles)= 9 hours.
(Note that the unit cancels out so you get the answer)
The final answer is 9 hours~
Answer:
Neither the normal distribution nor the t distribution applies.
Step-by-step explanation:
Hello!
The histogram attached shows the salary (in dollars) of 63 football players.
As you can see most of the values of this distribution are around 0 and the distribution is extremely asymmetrical (right skewed).
To apply a t-test to study the population average the population has to have a normal distribution.
The same goes for the standard normal distribution, but in this case, considering that the sample is large enough (n≥30) you can apply the Central Limit Theorem and approximate the distribution of the sample mean to normal X[bar]≈N(μ;δ²/n), but since the population variance is unknown, this is also not applicable.
The correct choice is the last one, since the conditions to apply the t test and the standard normal are not met.
I hope this helps!
The width is 10 and the length is 40
40*2 + 10*2 = 100
And 10*4= 40
