Step-by-step explanation:
In a certain company a salesman is paid a fixed salary for $3140 per month plus an annual commision of 2% on the TOTAL value of cars sold for the year. If the salesman sold cars valued at $720000 in 2009 calculate:
(i) his fixed salary for the year
(ii) the amount he recieved in commision for the year
(iii) his TOTAL income for the year
Answers
Step-by-step explanation:
(i) 12 months × fixed salary
= 12 × 3140
= 37680 $
(ii) commission = total × 2%
= 720000 × 0.02
= 14400 $
(iii) fixed salary + commission
= 37680 + 14400 = 52080 $
Given that lines P & R are parallel, find the values of x and y.
Answers
Answer: Y = 17 and X = 43
Step-by-step explanation:
p and r are parallel meaning both angles are the same.
So
3y = 51
divide them by 3
y = 17
Now we take 51 from 180 and we get 129
129 divided by 3x is
x = 43

Algorithms are the steps that would be converted into a program that a computer could use to process information, changing it from output to input.
Answers
Explanation: algorithms are steps that is used for data processing. It’s better to think of this as a flow chart. The input (usually from the user) goes in, the algorithm processes the information (this is where the input changes to an output), and spits out the output. This is the best answer out of all the options.
-x + 2y = 21

Answers
Answer:
(-5, 8)
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations using substitution/eliminationSolving systems of equation by graphingStep-by-step explanation:
Step 1: Define systems
-x + 2y = 21
5x + 6y = 23
Step 2: Rewrite systems
-x + 2y = 21
Subtract 2y on both sides: -x = 21 - 2yDivide -1 on both sides: x = -21 + 2yRearrange: x = 2y - 21Step 3: Redefine systems
x = 2y - 21
5x + 6y = 23
Step 4: Solve for y
Substitution
Substitute in x: 5(2y - 21) + 6y = 23Distribute 5: 10y - 105 + 6y = 23Combine like terms: 16y - 105 = 23Add 105 on both sides: 16y = 128Divide 16 on both sides: y = 8Step 5: Solve for x
Define original equation: 5x + 6y = 23Substitute in y: 5x + 6(8) = 23Multiply: 5x + 48 = 23Subtract 48 on both sides: 5x = -25Divide 5 on both sides: x = -5Step 6: Graph systems

A biologist estimates that 40% of the deer in a region carry a certain type of tick. For a sample of 300 deer selected at random, what is the probability that fewer than 124 deer have this tick?
Answers
Answer:
0.703
Step-by-step explanation:
By inspection this is a binomial probability distribution problem.
We are given;
Probability that the deer in a region carries a certain type of tick; p = 40% = 0.4
Sample size; n = 300
Now we want to find the probability that fewer than 124 deer have this tick.
Thus is at P(x ≤ 124)
Formula for binomial distribution problem is;
P(X = x) = C(n, x) × p^(x) × (1 - p)^(n - x)
But now in this question,
P(x ≤ 124) = P(0) + P(1) + P(2) +.... P(124)
Getting all the Probabilities from P(0) to P(124) is too long we will make use of an online binomial probability distribution calculator with the result attached as an image.
In the calculator we input n = 300; p = 0.4; and P(X ≤ x)
We have a value of 0.703

x = 10.4 (1dp)
Step-by-step explanation:
Using Pythagoras' theorem, a^2 = b^2 + c^2 where a is the hypotinues; b and c is the two sides
a^2 = b^2 + c^2
12^2 = 6^2 + x^2
144 = 36 + x^2
x^2 = 144 - 36
x^2 = 108
x = _/108

A DJ charges a setup fee plus an hourly fee to provide music for a dance party.
We know that the amount per hour is generally one-fourth of the number of setup feet. Let 'x' be the number of hours and 'y' be the total amount. Then the equation is given as,
y = 25x + 100
The equation best represents the amount spent will be y = 25x + 100. Then the right choice is C.
