A scale factor is a number multiplied to a certain number to determine the magnification of the quantity if the data. This is used to relate the effect of changing one parameter to the dependent variable. For example, if the temperature is doubled, then the volume increases by a factor of 2. To know the second volume, just multiply the first volume by 2.
So, an expansion factor must be more than 1. The greater the number, the greater the extent of expansion. Otherwise, if the factor is expression in proper fractions, the number is then reduced. The negative sign actually does not matter because it might be a vector quantity that expresses only the direction of motion, for example. From the choices, there are two fractions: 2/3 or 3/2. But since 3/2 is an improper fraction and is equal to 1.5, it is expansion because the factor is more than 1. Therefore, the scale factor for reduction is 2/3.
Answer:
2.28%
Step-by-step explanation:
If X is the random variable that measures the time of incubation needed before hatching, we want
P(X>343)
This is the area under the normal curve whose mean is 336 hours and its standard deviation 3.5 hours to the right of the point 343. (See picture attached)
This can be done easily with the help of a computer and we find
P(X>343) = 0.0228 or 2.28%
Answer:
Option C
Step-by-step explanation:
Zeros of a function are also called as x-intercepts of a function, which means where the graph/function intersects the x-axis.
In the image we see the graph intersects the x-axis at three points
x=0 , x=2 , x=4 so our answer is option C
Answer:
x = we can’t find the value of x because -5x has a variable and 9 doesn’t, so we can’t do anything.
