Answer:
57.62% of players weigh between 180 and 220 pounds
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
What percent of players weigh between 180 and 220 pounds
We have to find the pvalue of Z when X = 220 subtracted by the pvalue of Z when X = 180.
X = 220
has a pvalue of 0.7881
X = 180
has a pvalue of 0.2119
0.7881 - 0.2119 = 0.5762
57.62% of players weigh between 180 and 220 pounds
It could be 1:1 or 2:1 if you dont give them more than 1 apple and save some
Step-by-step explanation:
15+18+16=49 This is your total number of balls.
You have 15/49 green balls. Plug this fraction into a calculator: 15÷49. You get 0.306 To make this a percentage, multiply it by 100. You get 30.6 which rounds up to 31%. The probability of taking out a green ball is 31%. You can find the probability of the other colors by repeating the process. Message me if you have more questions.
Answer:
y = -1/8x + 35/8
Step-by-step explanation:
First, find the slope by subtracting 5 by 4 and -5 by 3. 5-4=1 and -5-3 equals -8. So, the slope is 1/-8. This is your current equation: y = -1/8x + b. Plug in one of your points to the equation, it doesn't matter which one. I'm going to use the second point, so it should look like this: 4 = -1/8(3) + b. -1/8 times 3 equals -3/8. So, this is what you should have: 4 = -3/8 + b. Add 3/8 to both sides of the equation to get 35/8 = b. Go back to your original equation and plug 35/8 in for b. This is your final equation: y = -1/8x + 35/8. Hope this helped!
Answer:
-1/2
Step-by-step explanation:
12x-36=-6
12x=36-6
x=30/12 = 5/2
For X-3 :
5/2 - 3 = -1/2
