Answer:
I think it is - 11.
Step-by-step explanation:
6x - 25 = 12x + 27 + 14
6x - 12x = 25 + 27 + 14
- 6x = 52 + 14
- 6x = 66
x = - 11
Answer:
H0: μ ≤ 34
H1: μ > 34
The z-test statistic is ≈ 1.8
The critical z-score is 1.28
we fail to reject the null hypothesis H0: μ ≤ 34
Step-by-step explanation:
H0: μ ≤ 34
H1: μ > 34
The z-test statistic is calculated using the formula:
z=
where
- X is the average class size found in the sample (35.6)
- M is the mean according to the null hypothesis (34)
- s is the standard deviation for class size (9)
then z= 
≈ 0.18
The critical z-score is 1.28 for α=0.10 (one tailed)
Because the test statistic is less than the critical value, do not reject the null hypothesis.
The modified r squared tells us more about the relationship among sales, price, as well as advertising by explaining approximately 60% of a variance in sales.
<h3>Define the term adjusted r squared?</h3>
R-squared (R2) would be a statistical measure that quantifies the proportion of the variation explained from an independent variable other variables within a regression model for a dependent variable.
- R-squared describes how much the variance with one variable describes the variance of the other.
- So, if a model's R2 is 0.50, the model's inputs can explain roughly half of a observed variation.
- A score of 70 to 100 shows that a specific portfolio closely reflects the underlying stock index, whereas a score of 0 to 40 indicates a relatively poor correlation the with index.
- Higher R-squared scores also suggest that beta measurements are more reliable. The volatility of either a security or portfolio is measured by beta.
Thus, the modified r squared tells us more about the relationship among sales, price, as well as advertising by explaining approximately 60% of a variance in sales.

Answer:
Option (1). 85°
Step-by-step explanation:
From the figure attached,
'l' and 'm' are the parallel lines and line 'n' is a transverse.
Since, m∠9 ≅ m∠13 [These angles are the corresponding angles]
Therefore, m∠13 = 95°
Since, m∠13 + m∠14 = 180° [Supplementary angles]
Therefore, 95° + m∠14 = 180°
m∠14 = 180° - 95°
m∠14 = 85°
Therefore, 85° will be the measure of angle 14.
Option (1) will be the answer.
