Answer:
( 24 / 3 ) + x
Step-by-step explanation:
the expression would be ( 24 / 3 ) + x
Answer:
Step-by-step explanation:
In point-slope form, our equation would be y - 9 = 2(x - 1). Expanding, we get y - 9 = 2x - 2. Solving for y, we obtain the form of the equation as shown in the problem: y = 2x + 7.
So, the numbers that would go in the blanks would be 2 and 7, respectively.
Answer: b=13, t=29
Step-by-step explanation:
Substituting the first equation into the second,

Answer: 2.3
Step-by-step explanation:
9.2 is divided by 4 is 2.3 so the last quarter is 2.3
Answer:
a) P=0.03
b) α=0.05
c) 0.72
d) 100
e) 0.72
Step-by-step explanation:
a) The P-value is the probability of the sample result. In this case the P-value is 0.03.
b) The level of significance is the threshold of probabilty for the null hypothesis to be reejcted or not. It is contrasted with the P-value to know if the effect is significant. In this case, the level of significance is 0.05.
NOTE: if it is a two-side test, the level of significance is 0.1 (two times 0.05).
c) The sample proportion is the one that results from the sample data. In this case, the sample proportion is 0.72.

d) The sample size is the amount of consumers reported. In this case is 100 customers.
e) The null value is 0.72 (equal to the sample proportion), because it is tested if there is no difference between the population proportion and the sample proportion.
