Step-by-step explanation:
Answer:
q = -4
q = -5/9
Step-by-step explanation:
Hi!
To solve this question, we can use the zero product property.
<h2>What is the Zero-Product property?</h2>
The zero product property states that if one factor is equal to 0, then the whol equation is equal to 0.
We have (q+4)(9q +5) = 0
That means either q + 4 = 0, or 9q + 5 = 0.
Solve:
- 9q + 5 = 0
- 9q = -5
- q = -5/9
We can check both cases:
(-4 + 4)(-36 + 5) = 0
0(-31) = 0
0 = 0
(-9/5 + 4)(9(-5/9) + 5) = 0
(2.2)(-5 + 5) = 0
(2.2)0 = 0
0 = 0
Answer:
The 95% confidence interval for the proportion of adolescents who tried smoking for the first time because of exposure to smoking in the movies is (0.37, 0.40).
Step-by-step explanation:
A confidence interval is an interval estimate of the population parameter. The confidence interval has a certain probability of consisting the true value of the parameter.
The (1 - <em>α</em>) % confidence interval for the population proportion (<em>p</em>) is given by:
The information provided is:
*Use a <em>z</em>-table for the critical value.
Construct the 95% confidence interval for the proportion of adolescents who tried smoking for the first time because of exposure to smoking in the movies as follows:
Thus, the 95% confidence interval for the proportion of adolescents who tried smoking for the first time because of exposure to smoking in the movies is (0.37, 0.40).
Answer:
X=1 9/10
Step-by-step explanation:
6X multiply 2 - 2X=19
Calculate the product
12X-2X=19
Collect the like terms
10X=19
Divide both sides of the equation by 10
X=19/10
Simplify the improper fraction
X=1 9/10
