1 answer:

7 0

Radian: is the standard unit of angular measure, used in many areas of mathmatics.
degree: is a measuement of plane angle, defined by representing a full rotation as 360 degrees.

Both are two units for measuring angles. There are at least four such units, but degrees and radians are most likely to encounter high school and college.

2x + 5 = 4 (5/4 - 1/2 x)

ruslelena [56]

Answer:

x=0

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x+5=−2x+5

Step 2: Add 2x to both sides.

2x+5+2x=−2x+5+2x

Step 3: Subtract 5 from both sides.

4x+5−5=5−5

4x=0

Step 4: Divide both sides by 4.

4x/4=0/4

X=0

Why are quartiles generally more reliable for judging outliers than mean and standard deviation?

lesya [120]

<span>Quartiles are generally more reliable for judging outliers than mean and standard deviations for 2 reasons. The mean is simply the average of all of the numbers, meaning that an outlier can easily be obscured by the masses. Standard deviation is a better method, however only going over by one standard deviation in either direction would also mask an outlier. A strong outlier however will pull a quartile farther in that direction than would normally be expected.</span>

Dairy farmers are aware there is often a linear relationship between the age, in years, of a dairy cow and the amount of milk pr

Jobisdone [24]

Answer:

B. A cow of 5 years is predicted to produce 5.5 more gallons per week.

Step-by-step explanation:

Let $M(a) = 40.8-1.1\cdot a$ , where $a$ is the age of the dairy cow, measured in years, and $M(a)$ is the predicted milk production, measured in gallons per week.

Besides, we consider $a_{1}$ and $a_{2}$ , such that $a_{1}\ne a_{2}$ , we define the difference between predicted milk productions ( $\Delta M$ ) below:
