Answer: a is 4 mm, c is 8 mm
Step-by-step explanation:
the 30-60-90 triangle rule: in a right triangle with 30, 60 and 90 degree angles, the adjacent side is [tex]\sqrt{3}[/tex] the opposite side, while the hypotenuse is 2 times the opposite.
the adjacent side in this case would be 4[tex]\sqrt{3}[/tex], a is opposite, and c is the hypotenuse
divide the adjacent side by [tex]\sqrt{3}[/tex] and we have the opposite side: 4
the hypotenuse is twice the opposite side, which has a value of 4. 4 times 2 is 8, which means the value of the hypotenuse is 8 mm

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.

6>w/-2 solve the inequalities
Answers
Answer:
w>-12
Step-by-step explanation:
6>w/-2 (Given)
6>-w/2 (Rewrite)
12>-w (Multiply both sides by 2)
-12<w (Remember to flip the sign when dividing or mulitplying by a negative)
w>-12 (Rewrite with w in front)
Therefore, w>-12 is the solution to the inequality.
Answer:
w>-12
Step-by-step explanation:
First, you you need to get rid of the -2 in w/-2 by multiplying -2 by both sides like this.
(-2)6>w/-2(-2)
Then you simplify it like this:
-12>w
However, since you multiplied/divided with a negative, you switch the inequality sign like this:
w>-12
And that's the answer!

Answers
Answer:
[tex]a_n=2n[/tex]
Step-by-step explanation:
The given sequence is 2, 4, 6, ....
We need to write an explicit formula for [tex]a_n[/tex]. The firts term is 2, second term is 4 and third term is 6 and so on.
Each term is 2 greater than the term before it. Thus we can write it as follows :
[tex]a_n=2n[/tex]
Where
n = 1,2,3....
Hence, the explicit formula is [tex]a_n=2n[/tex].

The equation of the line for the given data set of scatter plots will be y =- x. Since their Mean(M) is equal.
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.
so

0 2
5 1

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.

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
