Answer:
1/4
Step-by-step explanation:
Given
amount of salamanders, = 5
amount of crayfish = 3
amount of minnows = 12
Total fish = Total outcome = 5+3+12
Total outcome = 20
Since we are looking for the probability of selecting salamanders, our expected outcome will be 5.
Probability = expected outcome/total outcome
Pr( salamanders,) = 5/20
Pr( salamanders) = 1/4
Hence the probability of selecting salamanders, is 1/4
Hope this helps and best of luck!!

What is a point-slope equation of the line with slope -12 that goes through the point (5,3)?
Answer:
D. y - 3 = - 12 ( x - 5)
Step-by-step explanation:
Given
Slope (m) = - 12
Point = ( 5 , 3 ) = ( x1 , y1)
Now
Writing in point-slope equation we get
y - y1 = m( x - x1)
y - 3 = - 12 ( x - 5 )

2) Does the mapping diagram show a function?*
Answer:
No
Step-by-step explanation:
In order for it to be a function, every input (x values on the left) needs to be paired with only 1 output (y values on the right). Notice that 1 is paired with both 2 and 4. This means it is not a function, but it is paired with two different values.

Wyatt makes and sells rope doormats. He uses 200 feet of rope for each doormat. He wants to make 25 doormats. Which expression shows a correct way to find how many yards of rope he needs?
Answer: See explanation
Step-by-step explanation:
First and foremost, we should not that:
1 yard = 3 feet
We are informed that Wyatt uses 200 feet of rope for each doormat and that he wants to make 25 doormats.
The expression that shows a correct way to find how many yards of rope he needs will be:
= (200 × 25) / 3
= 5000/3
= 1666.67 yards

Answer:
∠10 + 12(3) = 46°
∠15(3) + 1 = 46°
Step-by-step explanation:
the angles are equal because they are corresponding angles
(10+12x) = (15x+1)
reduce:
3x = 9
x = 3
10 + 12(3) = 46°
15(3) + 1 = 46°

What is the value of s?
S=
Answer:
s = 1
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5 , then
sum = 180° × 3 = 540°
sum the interior angles and equate to 540
39s + 129 + 79 + 145 + 148 = 540 , that is
39s + 501 = 540 ( subtract 501 from both sides )
39s = 39 ( divide both sides by 39 )
s = 1

75=(4x-25)
What is the value of x?
Answer:
x = 25
Step-by-step explanation:
75 = (4x - 25)
Since there are no numbers outside of the parentheses, we can remove them.
75 = 4x - 25
Now we can see that we can add 25 to both sides.
100 = 4x
Divide both sides by 4 to isolate x.
25 = x
Check by plugging in the value into the original equation.
75 = 4(25) - 25
75 = 100 - 25
75 = 75
Your answer is correct.
Hope this helps!
Solve. 20/n+10 = 10/n+20 n = -10 n = -20 n = 30 n = -30
Answer:
20/n+10 = 10/n+20 n
multiply both side n,
n (20/n+10) = n(10/n+20 n)
20+10n = 10+20n^2
20+10n -20 = 10+20n^2 -20
10n = 20n^2 -10
10n - 10n = 20n^2 -10 -10n
0 = = 20n^2 -10 -10n
20n^2 -10 -10n = 0
n = 1 or n = -0.5

Jerry built a 2 inch cube to hold his marble collection. He wants to build a cube with a volume 8 times larger. How much will each edge measure?
Answer:
4 inches
Step-by-step explanation:
Jerry built a 2 inch cube to hold his marble collection.
Volume of this cube = 2³ = 8 cubic inches
He wants to build a cube with a volume 8 times larger.
Hence: 8 × 8 in³ = 64 in³
The measurement of each edge is calculated as:
√64 in³ = 4 inches

The equation y=21.2x represents Austin's earnings in dollars and cents, y,
for working x hours. Find the rate of change.
Given:
The equation is
[tex]y=21.2x[/tex]
Where, y is earnings for working in dollars and cents and x is the number of working hours.
To find:
The rate of change.
Solution:
The slope intercept form of a linear function is
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope and b is the y-intercept.
We have,
[tex]y=21.2x[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=21.2[/tex]
Therefore, the rate of change is 21.2 dollar and cents per hour.

Does anyone know how to solve this?
Answer:
The correct option is c.
Step-by-step explanation:
Given that,
u = 7i+4j and v = 2i-3j
We need to find the product of u and v. The dot product of two vectors is given by :
[tex]u{\cdot}v=(7i+4j){\cdot} (2i-3j)\\\\=(7i)(2i)+(4j)(-3j)\\\\=14-12\\\\=2[/tex]
So, the dot product of u and v is equal to 2.
