Answer:
His loading speed would be 3 trucks in 1 hour
Answer:
2.2 seconds.
Step-by-step explanation:
We have been given that an astronaut on the moon drops a tool from the door of the landing ship. The quadratic function 
models the height of the tool, in meters, after x seconds.
To find the time, it will take for the tool to hit the surface of moon, we will set 
and solve for x as:
Divide both sides by negative 2:
Now, we will take square root of both sides:
Since time cannot be negative therefore, it will take 2.2 seconds for the tool to hit the surface of the moon.
Answer:
C+11/c+9
Step-by-step explanation:
3c+33/3c+18 = c+11 / c+6
C^2+17c +66 = (c+6)(c+11)
C^2 +20c+99 = (c+11)(c+9)
So the given question becomes
{C+11/c+6} {(c+6)(c+11)/(c+11)(c+9)}
= c+11 /c+9
Answer:
Correct option is (B) descriptive statistical method
Step-by-step explanation:
Descriptive statistics branch in statistics deals with the representation of the data using distinct brief coefficients. These coefficients are used as either the representative of the sample or the population.
The descriptive statistics branch is divided into two sub branches:
- Measure of central tendency
- Measure of dispersion.
The three measures of central tendency are:
- Mean (or Average)
- Median
- Mode.
The measures of dispersion are:
- Variance
- Standard deviation
- Range
- Kurtosis
- Skewness
The education researcher computes the average number of hours student study at various local colleges.
The average of a data is the mean value which is the measure of central tendency.
Thus, the researcher is using descriptive statistical method to summarize the data.
Answer:
$156
Step-by-step explanation:
To find how many pounds of potatos an amount is, it's valuable to find how much *one* pound is
With just dividing both sides by 30, we can get that one pount of potatos costs $12
Since we want how much 13 pounds we cost, simply multiple 12 by 13 which gives us an amount of $156
