Andres works 20 hours per week at a part-time job. His original pay rate was $10.00 per hour, but he recently received a pay raise of x dollars per hour. His new total weekly pay, y, is represented by the equation y=20(10+x).
If Andres earned $210 last week, what was the amount of Andres' raise per hour?
Answer:
50 cents / hour.
Step-by-step explanation:
y=20(10+x)
210 = 20(10 + x)
210 = 200 + 20x
20x = 10
x = 0.5.
Answer: $0.5
Step-by-step explanation:
Pay for week = 20h × $10
$200
Raise = x
New weekly pay = y = 20 (10+x)
Last week = $210
$210 = 20 (10+x)
$210 ÷ 20 = 10+ x
10.5-10 = x
$0.5 = x

What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that a toy store manager received a large order of Mr. Slinkums just in time for the holidays. The manager places 20% of them on the shelves, leaving the other 120 Mr. Slinkums in storage.
The number of the Mr. Slinkums in the order will be calculated as,
Number = ( 120 x 100 ) / 80 - 120
Number = 150 - 120
Number = 30
Hence, the number of the order will be 30.

find the slope of the line containing the points (-2,5) and (-2,0)
Step-by-step explanation:
Hey there!
x1= -2 and y1=5
x2=-2 and y2=0
The slope of a line having two lines are;
[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]
Put all values.
[tex]m = \frac{0 - 5}{ - 2 + 2} [/tex]
Simplify it.
[tex]m = \frac{ - 5}{0} [/tex]
= undefined. [ Because something divided by 0 is undefined].
Therefore, the slope is undefined.

What is the difference between an estimator and an estimate? A. An estimator is a function of a sample of data to be drawn randomly from a population whereas an estimate is the numerical value of the estimator when it is actually computed using data from a specific sample. B. Both an estimator and an estimate are functions of a sample of data to be drawn randomly from a population. C. Both an estimator and an estimate are numerical values computed using data from a specific sample. D. An estimate is a function of a sample of data to be drawn randomly from a population whereas an estimator is the numerical value of the estimator when it is actually computed using data from a specific sample. Determine whether the following are examples of estimators, estimates or neither. A. . estimator estimator estimate neither B. . estimate estimate neither estimator C. . neither neither estimator estimate D. . estimate neither estimate estimator E. . estimate estimate neither estimator
Answer: A. An estimator is a function of a sample of data to be drawn randomly from a population whereas an estimate is the numerical value of the estimator when it is actually computed using data from a specific sample.
Step-by-step explanation: The estimator is simply used to on obtaining an estimate from a sample of data. Thus, the estimator may be described as a function built according to a set of defined rules and statistical component which is used to infer a numerical value of an estimate from a given sample of observed data. Hence, the estimator may be regarded as the function or rules adopted in our quest to obtain an estimate for a given population from a sample of data. The value obtained for the mean of a sample of data is called an estimate of the population, the rules for Deriving the estimated value is called the estimator.

Solve 3^x−5 = 9. please
Assuming the -5 is with the x
You have 3^(x-5) =9
Convert the 9 to base 3: 3^2 = 9
Now you have:
3 ^(x-5) = 3^2
Now solve for exponents:
X-5= 2
Add 5 to both sides:
X = 7
Add five on both sides. Divide both sides by three
Answer: x = 4.66666666667

One of the Same side angles of two parallel lines is 60° greater than the other. Find the two angles.
Answer:
60,120
Step-by-step explanation:
We know that angles on the same side of the transversal always add up to 180 ( are supplementary)
Hence, taking one of the angles as x we get,
x+(60+x)=180
2x+60=180
2x=120
x=60
Hence, one angle is 60 degrees while the other 120 degrees

2.111 (4 points) An art dealer receives a shipment of five old paintings from abroad, and, on the basis of past experience, she feels that the probabilities are, respectively, 0.76, 0.09, 0.02, 0.01, 0.02, and 0.10 that 0, 1, 2, 3, 4, or all 5 of them are forgeries. Since the cost of authentication is fairly high, she decides to select one of the five paintings – 2– MATH-4751/6751, Fall-2020 Homework #3 at random and send it away for authentication. If it turns out that this painting is a forgery, what probability should she now assign to the possibility that all the other paintings are also forgeries?
Answer:
0.675675675 = 67.57%
Step-by-step explanation:
P(P₀) = 0.76
P(P₁) = 0.09
P(P₂) = 0.02
P(P₃) = 0.01
P(P₄) = 0.02
P(P₅) = 0.1
P(F) is the probability that the first painting is a forgery
P(F | P₀) = 0
P(F | P₁) = 0.2
P(F | P₂) = 0.4
P(F | P₃) = 0.6
P(F | P₄) = 0.8
P(F | P₅) = 1
P(P₅ | F) = [P(F | P₅) x P(P₅)] / {[P(F | P₁) x P(P₁)] + [P(F | P₂) x P(P₂)] + [P(F | P₃) x P(P₃)] + [P(F | P₄) x P(P₄)] + [P(F | P₅) x P(P₅)]}
P(P₅ | F) = (1 x 0.1) / [(0.2 x 0.09) + (0.4 x 0.02) + (0.6 x 0.01) + (0.8 x 0.02) + (1 x 0.1)] = 0.1 / (0.018 + 0.008 + 0.006 + 0.016 + 0.1) = 0.1 / 0.148 = 0.675675675 = 67.57%
