Choice D is the correct answer.
For translations, moving to the right 5 units means you add 5 to x, and moving down 2 units means you subtract 2 from y. D is the only choice that accurately represents this.

Answer:
b) 95%
Step-by-step explanation:
We have been given that scores on an approximately bell shaped distribution with a mean of 76.4 and a standard deviation of 6.1 points. We are asked to find the percentage of the data that is between 64.2 points and 88.6 points.
First of all, we will find z-scores of each data point as:




Let us find z-score corresponding to normal score 88.6.



To find the percentage of the data is between 64.2 points and 88.6 points, we need to find area under a normal distribution curve that lie within two standard deviation of mean.
The empirical rule of normal distribution states that approximately 95% of data points fall within two standard deviation of mean, therefore, option 'b' is the correct choice.
By dividing the area of the polygon with the circles area.
We first should find how 7 relates to the 21 girls.
To do this we can divide.
The 21 girls by the 7 ratio
21 divided by 7 is 3
So 1 out of 7 in the ratio is 3 girls
We can now move this over to the boys.
If 1 means 3, and their are a ratio of 5 boys
We do 5 x 3,
Which equal 15.
Their are 15 boys in 7th grade.
