<span>0.4332
The problem is asking what proportion of a normal distribution is within 1.50 standard deviations on the positive half of the curve. So let's take a look. First thing is to figure out what would be a reasonable answer. Looking at the standard deviation, there will be 34.1% within 0 to +1 standard deviations. And there will be 47.7% within 2 standard deviations. So the correct answer will be something between 0.341 and 0.477. So let's look at the possible answers.
​0.4332 - This answer falls within the desired range. It's a candidate.
​0.8664 - This answer is way too large. Well over 50%, so it can't work.
​0.0668 - This answer is way too small. So once again, it can't work
​0.9332 - If the 0.8664 above was too large, imagine how unreasonable this answer is. Also wrong.
So of the 4 available choices, only 0.4332 is possible. So that's the correct answer.</span>
Answer:
The probability of spinning and even number on the spinner is 0.4.
Step-by-step explanation:

Period of sin wave = 1/2
Period of parent sine function is 2π.
This means the x value of sine function (sin(x)) has to be divided by 4π to get a period of 1/2 because 2π/4π = 1/2
Thus, our function will be of the form:
Maximum Value = 10
Minimum Value = -4
Amplitude of the function = (Maximum Value - Minimum Value)/2
So, amplitude of the function is 7
Thus, the function will be of the form:
The function has a y-intercept other than zero, this means the function will be of the form:
The y-intercept is 3. This means for x=0, y=3. Using the values, we get:
Thus the equation of the sinusoidal function becomes:
Answer:
You have to add the perimeter of + 4 and 5 + 1.
Step-by-step explanation:
Remember when it says "area" that means multiply but "perimeter" means addition.
