Step-by-step explanation:
When you translate, you add or subtract the value you are moving to each coordinate
(6,7) left 5 would be -5 to the x coordinate and 3 up would be +3 to the y coordinate.
6-5=1
7+3=10
new point is (1,10)
moving left 5 units is subtracting 5 from the x value:
6-5 = 1
Moving up 3 units is adding 3 to the y value:
7 + 3 = 10
The answer is (1,10)

Find the area of the figure
Answers
Answer:
89 m²
Step-by-step explanation:
It should be no surprise that the area can be found as the difference between the area of the enclosing rectangle and the area of the triangular cutout.
The rectangle area is given by ...
A = LW
A = (13 m)(8 m) = 104 m²
The base width of the triangular cutout is 13 m - 4 m - 4 m = 5 m. The area of that cutout is given by ...
A = 1/2bh
A = 1/2(5 m)(6 m) = 15 m²
Then the area of the shaded figure is ...
104 m² -15 m² = 89 m²

Find the surface area of the prism.
Answers
Answer:
326m²
Step-by-step explanation:
Find the area of each side and find the total sum from each individual area:

So the surface area of the prism is 326m²
A set of data is normally distributed with a mean of 455 and a standard deviation of 25. What percent of the data is in the interval 405–455?
a.
47.5%
c.
68.3%
b.
49.85%
d.
34.15%
Answers
Answer:
a. 47.5%
Step-by-step explanation:
1. Find the z-score for 405: 405-455/25 = -2
2. Find the z-score for 455: 455-455/25 = 0
3. Using technology or a chart, find the percentage that corresponds with the z-scores: -2 = 0.0228 or 2.28%, AND 0 = 0.5000 or 50%
4. Find the difference between the percentages by subtracting them: 50% - 2.28% = 47.72%
5. Most of the time, the answers aren't exact, so since 47.72% is closest to 47.5%, I would say that's the answer.

What is the Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Given a data set of the number of text messages sent (x) and text messages received (y) by 10 students in a half hour.

Where M of x = 11.9
also the M of y = 11.9
Sum of X = 119
Sum of Y = 119
Mean X = 11.9
Mean Y = 11.9
The sum of squares (SSX) = 504.9
The sum of products (SP) = 504.9
Regression Equation = ŷ = bX + a
b = SP/SSX = 504.9/504.9 = 1
a = MY - bMX = 11.9 - (1*11.9) = 0
ŷ = 1X - 0
Thus the equation of line best fit will be y = x.
