We have 20 equally probable events in the table. So, each box has probability equal to 1/20.
With this in mind, we must find the numbers 3 and 4 in each box. Then, we can see that there are 12 boxes containing these numbers. Therefore, the probability to catch a bass is
[tex]\begin{gathered} P(\text{bass)}=12\cdot(\frac{1}{20}) \\ P(\text{bass)}=\frac{12}{20} \\ P(\text{bass)}=\frac{3}{5} \end{gathered}[/tex]By converting these result in percentage, we have
[tex]\frac{3}{5}\cdot100=60[/tex]that is, 60% could be bass fish.

Sam has $4.30 in quarters and nickels. He has 26 coins in all. The following system of equations can be used to represent this situation. 0.25q +0.05n = 4.30 q+n=26 What does the solution to the system (q, n) represent? (4 pts.) A.There is not enough information to determine. B.The value of the quarters and nickels Sam has C.The number of quarters and the number of nickels Sam has. D.The total amount of money Sam has.
ANSWER
C.The number of quarters and the number of nickels Sam has.
EXPLANATION
We have that the system of equations representing the situation is:
0.25q + 0.05n = 4.30
q + n = 26
The solution to the system of equations (q, n) will represent the number of quarters and nickels that Sam has.
This is because the sum of q and n is 26 and we are told that Sam has 26 coins.
Therefore, we can conclude that (q, n) represents the number of quarters and nickels that Sam has.

Find the quotient. If possible, rename the quotient as a mixed number or a whole number. Write your answer in simplest form, using only the blanks needed.
The quotient is 11/40.
What is a mixed number?It is formed by combining three parts a whole number, a numerator and a denominator. Here, the numerator and denominator are a part of the proper fraction that makes the mixed number. These are also known as mixed fractions. It contains both an integer or a whole number. A mixed fraction or number is therefore a product of a whole number and a proper fraction.
2 3/4= 11/4
11/4 is divided by 10 then,
It becomes 11/40
So, the quotient is 11/40

Given 8 x = 2 y - z, solve for y if x 2 and z = 2.
Answer
y = 9
Explanation
The question wants usto solve for y, given that
8x = 2y - z
if x = 2 and z = 2
To solve this, we just substitute the given values for x and z into the given expression to get y.
8x = 2y - z
8(2) = 2y - 2
16 = 2y - 2
We can rewrite this and have
2y - 2 = 16
Add 2 to both sides
2y - 2 + 2 = 16 + 2
2y = 18
Divide both sides by 2
(2y/2) = (18/2)
y = 9

emily bought a pair of headphones on sale, if they usually cost 36.80, and emily purchased them at 40% how much did she pay? PLEASE GIVE ME A STEP BY STEP EXPLANATION PLEASE
Emily will pay $22.08 to buy the headphones after the discount of 40%.
Define percentage discountWhen a product is offered at a discount, the seller is reducing the product's price from what it was originally listed for. The percentage discount on the product is determined by the discount amount stated as a percentage of the original price.
Given data -
Cost of headphones - $36.80
Total price of product is considered as a 100%.
As Emily purchased them at 40%, she should be paying 60% of the amount.
Therefore, the amount she is paying to buy the headphones
= 60% of $36.80
= [tex]\frac{60}{100}[/tex] * $36.80
= 0.6 * $36.80
= $ 22.08
Emily will pay $22.08 to buy the headphones.

kareem correctly answered 85% of the questions on his math test. He missed 6 questions. How many questions were on his test
Answer:
40 questions
Explanation:
The total number of questions on his test represents 100%.
So, If he correctly answered 85% of the questions, then he missed 15% of the questions because:
100% - 85% = 15%
Therefore, 15% of the questions are equivalent to 6 questions, then we need to find the number equivalent to 100%. So 100% is equivalent to:
[tex]100\text{ \% }\times\frac{6}{15\text{ \%}}=40[/tex]Then, there were 40 questions on his test.

construct the perpendicular bisectors of each side of the triangle. Extend the bisectors until they intersect each other.
Solution:
Given:
To draw the perpendicular bisector of each side, place the compass at the two ends of the line.
Using the line WX, expand the compass to beyond half of the line and place the compass at the first point (point W), to draw an arc above and below.
Then place the compass at the other point of the line (point X), and draw an arc to intersect the initially drawn arcs.
Join the two points of intersection to get the perpendicular bisector of the line.
Repeat the same for the other two sides to get the perpendicular bisectors.

A certain paint mixture weighing 300 lb contains 20% solids suspended in water. How many pounds of water must be allowed to evaporate to raise the concentration of solids to 22%?
27.27 lb of water must be allowed to evaporate
Explanations:Weight of the paint mixture = 300 lb
The paint mixture contains 20% solids suspended in water
Weight of solids suspended in water = (20/100) x 300
Weight of solids suspended in water = 60 lb
Let the weight of the mixture after evaporation be w
[tex]\begin{gathered} \frac{22}{100}\times w\text{ = 60} \\ 0.22w\text{ = 60} \\ w\text{ = }\frac{60}{0.22} \\ w\text{ = }272.73\text{ lb} \end{gathered}[/tex]The weight of the mixture after evaporation = 272.73lb
The weight of water that will be allowed to evaporate = 300 lb - 272.73 lb
The weight of water that will be allowed to evaporate = 27.27 lb
Therefore, 27.27 lb of water must be allowed to evaporate

What is the acceleration of a 50 kg object pushed with a force of 500 newtons?10 m/s225,500 m/s2490 m/s225 m/s2
Let's use Newton's second law of motion:
F = m*a
Where:
F= Force = 500
m = mass = 50
a = acceleration
So:
500 = 50*a
Solve for a:
Divide both sides by 50:
500/50 = 50a/50
10 = a
a = 10m/s²

[tex](-\frac{2}{3},\frac{75}{9})[/tex]is it possible for a rhombus to have a angle of 120 degrees and a angle of 30 degrees ? homework question
Solution:
From the properties of a Rhombus;
Opposite angles of a rhombus are equal.
The adjacent angles of a rhombus are supplementary, i.e. adds up to 180°
If one of the angles of a rhombus 120°, and the sum of the adjacent angles is 180°, then, the adjacent angle will be 60° (180° - 120° = 60°)
If one of the angles of a rhombus is 30°, then, the adjacent angle will be 150° (180° - 30° = 150°)
Thus, the sum of 120° and 30° is not supplementary and definitely can not be adjacent, since they do not sum up to 180°.
Hence, it is not possible
