Answer:
4.1
Step-by-step explanation:
X+ 7.8 = 11.9
X= 11.9 - 7.8
X= 4.1
Answer:
x = 4.1
Step-by-step explanation:
To solve for x, subtract 7.8 from both sides of x + 7.8 = 11.9:
x + 7.8 - 7.8 = 11.9 - 7.8, or
x = 4.1

The dot plot shows the number of hours Stan worked each week for the last 3 months.
What fraction of the total number of weeks did Stan work 15 or more hours? Express in simplest form.
A. 5/7
B. 1/6
C. 1/5
D. 5/12
The image with the dot plot is attached.
Answer:
D. 5/12
Step-by-step explanation:
The dot plot shows the number of hours Stan worked and in order to know the number of weeks that he worked 15 hours or more, you have to count the dots that are between 15 and 18 hours. So, you have 3 dots in 15 hours, 1 dot in 16 hours and 1 dot in 18 hours. If you add this numbers (3+1+1=5), this means that he worked 5 weeks 15 or more hours. This number would be the numerator in your fraction. Then, the denominator would be the total amount of weeks and to find that you can count all the dots. The total number of dots is 12.
So, the fraction that represents the total number of weeks that Stan worked 15 or more hours is: 5/12. This is the simplest form because this numbers don't have any common factors other than 1.

2) Given: lines a and b are parallel
Prove: m<1 = m<8
Explanation:
* Demonstrate that the related angles are the same.
* Demonstrate that different interior angles are equivalent.
* Demonstrate the adjacent interior angles are supplementary.
* Demonstrate the adjacent external angles are not mutually exclusive.
* Show that the lines in a plane are perpendicular to the same axis.
<1 and <8 are the same because they are alternate exterior angles that means that they are
Opposite sides of the transversal.
And that they are on the exterior side of the parallel lines.
Now because of that they have the same measures no matter what so would

Answer:
H was (Hx,Hy) goes to (Hy,-Hx)
G was (Gx,Gy) goes to (Gy,-Gx)
I was (Ix,Iy) goes to (Iy,-Ix)
Step-by-step explanation:
Rotating about the (0,0), the distance from any point to the origin (the hypotenuse of the triangle formed) never changes. A 90 clockwise rotation moves the point to the next quadrant, so side a and side b must flip to maintain the distance. You just need to flip the coordinates and change the sign of the new Y. If you plot a few random points and use a compass to rotate them 90 I think you will find this works.
Evaluate the six trigonometric ratios for ø.
I need sin, cos, tan, csc, sec, and cot please.
Trigonometry.
Answer:
See below
Step-by-step explanation:
First off, the missing side is c=√(17²-8²)=15
sinø=opposite/hypotenuse=15/17
cosø=adjacent/hypotenuse=8/17
tanø=opposite/adjacent=15/8
cscø=hypotenuse/opposite=1/sinø=1/(15/17)=17/15
secø=hypotenuse/adjacent=1/cosø=1/(8/17)=17/8
cotø=adjacent/opposite=1/tanø=1/tanø=1/(15/8)=8/15
What is the result of subtracting (22 - 4x +1) from (3x2 + 5x - 2) ?
Answer:
−9x+19
Step-by-step explanation:
Answer: −9x+25−3x^2
Step-by-step explanation:
1) Simplify 22-4x+122−4x+1 to -4x+23−4x+23.
−4x+23−(3x 2+5x−2)
2) Remove parentheses.
−4x+23−3x^2−5x+2
3) Collect like terms.
(−4x−5x)+(23+2)−3x^2
4) Simplify
Given the following probabilities, determine whether
the events A and B are independent or dependent.
P(a) x p(b) = 2/5 x 1/4 = 2/20 = 1/10
1/10 does not equal 1/9 so the event is dependent
The answer is B ( the second choice)
Which bacteria sample (A or B) had a smaller initial population? What was that value?
Answer:
B has a smaller initial population of 500
Step-by-step explanation:
Given
See attachment for complete question
Required
The bacteria with the smaller initial population
The initial population is at x = 0
For bacteria A;
[tex]A(x) = 600[/tex] when [tex]x = 0[/tex]
For bacteria B, we have:
[tex]B(x) = 500(2)^x[/tex]
Substitute 0 for x
[tex]B(x) = 500(2)^0[/tex]
[tex]B(x) = 500*1[/tex]
[tex]B(x) = 500[/tex]
So; when x = 0
[tex]A(x) = 600[/tex] and [tex]B(x) = 500[/tex]
Because; 500 < 600
We can conclude that B has a smaller initial population of 500
