5t=9y + 22 solve for y

inna [77]

Solve for y:
5 t = 9 y + 22
5 t = 9 y + 22 is equivalent to 9 y + 22 = 5 t:
9 y + 22 = 5 t
Subtract 22 from both sides:
9 y = 5 t - 22
Divide both sides by 9:
Answer: y = (5 t)/9 - 22/9

Answer:

The 99% confidence interval for p in this case is (0.3317, 0.5883).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

Randomly selects 100 students from the school and asks the President to name each one. The President is able to correctly name 46 of the students.

This means that:

$n = 100, \pi = \frac{46}{100} = 0.46$
