Yes because angle A is 25 degrees
Answer: 40%
Step-by-step explanation:
first you symplify your fraction:
12/30 = 2/5
then divide your numerator from your denominator:
2÷5 =0.4
then you convert your decimal into a percentage:
0.4×100=40%
Answer:
not sure what type you mean but here are options
Step-by-step explanation:
30+4=34
thirty-four
Answer:
Explained below.
Step-by-step explanation:
The regression analysis output is as follows:
Coefficients Standard Error t Stat P-value
Intercept 7.856710924 1.316226455 5.969118 0.001889
Music Video 0.094781123 0.027926367 3.393965 0.019378
Views
R-sq. = 69.73%
R-sq. (adj) = 63.68%
A
There are two variables used in this study, the independent and the dependent variable.
The independent variable is the number of online music video views and the dependent variable is the number of guitar sales.
B
The coefficient of determination R² specifies the percentage of the variation in the dependent variable (Y) that is forecasted or explained by linear regression and the forecaster variable (X, also recognized as the independent-variable).
Thus, the proportion of the variation of guitar sales that is explained by its linear relationship to music video views is 69.73%.
C
The least square regression line is:
The least square regression line implies that there is a positive relationship between the guitar sales and music video views. That is as the number of music video views increases the guitar sales increases. And vice-versa.
Thus, increased guitar sales were caused by online music video views.
Answer:
The candle has a radius of 8 centimeters and 16 centimeters and uses an amount of approximately 1206.372 square centimeters.
Step-by-step explanation:
The volume (), in cubic centimeters, and surface area (), in square centimeters, formulas for the candle are described below:
(1)
(2)
Where:
- Radius, in centimeters.
- Height, in centimeters.
By (1) we have an expression of the height in terms of the volume and the radius of the candle:
By substitution in (2) we get the following formula:
Then, we derive the formulas for the First and Second Derivative Tests:
First Derivative Test
There is just one result, since volume is a positive variable.
Second Derivative Test
If :
(which means that the critical value leads to a minimum)
If we know that , then the dimensions for the minimum amount of plastic are:
And the amount of plastic needed to cover the outside of the candle for packaging is:
The candle has a radius of 8 centimeters and 16 centimeters and uses an amount of approximately 1206.372 square centimeters.
