Answer:
23
Step-by-step explanation:
Since it says f(x) that means that when we see f(-6) we are substituting x for -6.
This means that the equation will become
f(-6) = -3(-6) + 5
First multiply -3 and -6 (18)
f(-6) = 18 + 5
Next add 18 and 5 (23)
This means that f(-6) = 23
23
This problem is basically asking you to plug in -6 for x and solve using the order of operations (PEMDAS)
[tex]f( - 6) = - 3( - 6) + 5[/tex]
[tex]f( - 6) = 18 + 5[/tex]
[tex]f( - 6) = 23[/tex]
Solve F(x) for the given domain. Include all of your work in your final answer. Submit your solution. F(x) = x2 + 3x - 2
Answer:
F(a) = a² + 3a - 2
F(x-1) = x² + x -4
Step-by-step explanation:
Note:
Domain is missing, assume domain
F(a)
F(x-1)
Given:
F(x) = x² + 3x - 2
Computation:
1. F(x) = x² + 3x - 2
So,
⇒ F(a) = a² + 3a - 2
2. F(x-1) = (x-1)² + 3(x-1) - 2
F(x-1) = x² + 1 -2x + 3x - 3 - 2
F(x-1) = x² + x -4

what is 5.267 in word form
Answer:
five and two hundred sixty-seven thousandths
Step-by-step explanation:
Answer: Five and Two hundred sixty-seven thousandths.
Anything number that has a decimal you must have and.
Put a decimal in word form the word and becomes the decimal.
Any number without a decimal you do not need to put and.
So if 5.267 was actually 5,267 you'll just say five thousand two hundred sixty-seven.

1. Again we have two methods, A and B, available for teaching a certain industrial skill. There is an 80% chance of successfully learning the skill if method A is used, and a 95% chance of success if method B is used. However, method B is substantially more expensive and is therefore used only 25% of the time (method A is used the other 75% of the time).
A worker learned the skill successfully. What is the probability that he was taught by method A?
2. Again we have two methods, A and B, available for teaching a certain industrial skill.

However, method B is substantially more expensive and is therefore used only 25% of the time (method A is used the other 75% of the time).
What does a correct probability tree for this problem look like?
Answer:
The probability that a worker was taught by method A given that he learned the skill successfully is 0.72.
Step-by-step explanation:
(1)
The information provided is:
A = if method A is used
B = if method B is used
S = successfully learning the skill
P (A) = 0.75
P (B) = 0.25
P (S|A) = 0.80
P (S|B) = 0.95
Compute the probability that a worker was taught by method A given that he learned the skill successfully as follows:
[tex]P(A|S)=\frac{P(S|A)P(A)}{P(S|A)P(A)+P(S|B)P(B)}[/tex]
[tex]=\frac{0.80\times 0.75}{0.80\times 0.75+0.95\times 0.25}\\\\=\frac{0.60}{0.60+0.2375}\\\\=\frac{0.60}{0.8375}\\\\=0.716418\\\\\approx 0.72[/tex]
Thus, the probability that a worker was taught by method A given that he learned the skill successfully is 0.72.

If the mean score on a stress test is 5, the standard deviation is 2, and the distribution is normal, what would be the mean value when converted to a z distribution
Answer: 0
Step-by-step explanation:
Given that :
Mean score on test = 5
Standard deviation on test = 2
Distribution = normal
The mean value when Converted to a z - distribution :
Zscore = (x - mean) / standard deviation.
Hence z score for the mean score will be :
X = mean score
Zscore = ( 5 - 5) / 2
Zscore = 0 / 2
Zscore = 0
Mean value when Converted to a z distribution will be 0
What is the value of a for the equation below?
15 + 2a = 35
a = 10
a = 5
a = 20
a = 25
Steps to solve:
15 + 2a = 35
~Subtract 15 to both sides
2a = 20
~Divide 2 to both sides
a = 10

Joe and Susan were arguing about how
many basic operations existed in math. Joe
argued that there are only 4 operations (addition,
subtraction, multiplication, and division). Susan
disagreed and said there are only 2 operations.
She made a case that when you subtract its just
adding a negative and when you divide its
multiplying by a fraction. Do you agree with
Susan? What is your opinion on this matter?
Answer:
The correct number of basic operations that exist in mathematics is four (addition, subtraction, multiplication and division) because the definition of an operation is the carrying out of a task by the application of principles and these four operation are arithmetic operations that have precedence rules or order of operations, such that we must first multiply or divide before adding or subtracting
Division is different from simply multiplying by a fraction because in Euclidean division, the result is a quotient and a remainder, which shows that division can yield more than one result while multiplication yields a single result
For subtraction and addition, one of the differences is that subtraction cannot be simply commuted
a - b = -(b - a)
Subtraction is non-associative;
a - b - c when arranged as (a - b) - c and a - (b - c), can yield different results depending on operation order which is unlike addition
Therefore, the four basic operations in mathematics are addition, subtraction, multiplication and division

What is the greatest amount of money that rounds to $108.60 when rounded to the nearest dime? What is the least amount of money that rounds to $108.60? Explain your answers.
Answer:
$108.59Step-by-step explanation:
The dime which is worth 0.10 U.S. dollar, is a ten-cent coin, one-tenth of a United States dollar
the value is 0.1
Now in rounding up of numbers the dime is located one decimal place away i.e 0.5 in the number given in the problem statement
to round up to the nearest dime we have to consider the next number to the dime if this number is greater than 5 we will round up if it is less than five we can not perform any rounding up operation
hence the greatest amount of money is
since the number next to 5 is 9 and 9 is greater than 5 we will round up from 5 to 6
This makes 108.59 the greatest amount of money that rounds to $108.60
A cashier has a total of 30 bills , consisting of $1 bills, $5 bills and $20 bills. The total dollar amount of these bills is $351. There are nine more $20 bills than $1 bills. How many of each bill denomination are there ?
Answer:
Five= 9 One= 6 Twenty= 15
Step-by-step explanation:
A cashier has a total of 30 bills, made up of ones, fives, and twenties.
o+f+t=30,
The number of twenties is 9 more than the number of ones.
t=9+o,
The total value of the money is $351.
o+5f+20t=351
so we have
o+f+t=30, t=9+o,
o+5f+20t=351
f = 9, o = 6, t = 15

A student has 8 pints of iced tea in a pitcher. The amount of iced tea in the pitcher is a function of x, the amount of iced tea she has poured from the pitcher, y. What is the domain of this function? a \large 0\le x\le8 b \large \left\{1,2,3,4,5,6,7,8\right\} c \large 0\le y\le8 d \large \left\{0,1,2,3,4,5,6,7,8\right\}
Answer: The domain is:
0 pints ≤ x ≤ 8 pints.
Step-by-step explanation:
When we have a function:
y = f(x)
The domain is the set of the possible values of x (the possible inputs).
In this case, the value of x represents the amount of tea that she has poured from the pitcher.
Now, initialy the pitcher has 8 pints, so the smallest possible value of x is 0 pints (when she has not pured anithing) and the maximum value of x is 8 pints (when she has poured all the 8 pints).
So we have the domain:
0 pints ≤ x ≤ 8 pints

Determina si el número 2,340 es divisible por 2,3,5,9,y 10. Explica tu respuesta.
Answer: The number 2340 is divisible by 2,3,5,9 and 10
=====================================================
Here's why
2340/2 = 1170 is a whole number, so it is divisible by 2
Note how the last digit is an even number, so overall the number is even and divisible by 2
---------------
Add the digits of the given number to get 2+3+4+0 = 9, showing that it is both divisible by 3 and also divisible by 9. If the digits add to a multiple of 3, then it is divisible by 3. If the digits add to a multiple of 9, then it is divisible by 9. Basically anything divisible by 9 is automatically divisible by 3 as well.
We can see we get whole number results shown below
2340/3 = 780
2340/9 = 260
---------------
The last digit is 0, so 2340 is a multiple of 10. It is also a multiple of 5 because 10 = 5*2
And we can see that
2340/5 = 468
2340/10 = 234
Showing 2340 is a multiple of 5 and 10.
m∠XWY is twice ∠XWZ. Explain whether JJJG WZ must be the angle bisector of ∠XWZ.
The measure of the angle ∠XWZ will be half of the measure of the angle ∠XWY.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The measure of the angle ∠XWY is twice the measure of the angle ∠XWZ.
∠XWY = 2 ∠XWZ
Simplify the equation, then we have
∠XWZ = ∠XWY / 2
Then the measure of the angle ∠XWZ will be half of the measure of the angle ∠XWY.
