Answer:
all positive numbers
Step-by-step explanation:
You want to know the domain of the log function.
Log functionThe log function ln(x) is defined for all x > 0. A log function with any other base is similarly defined.
log function domain: all positive numbers
A parent log function has a vertical asymptote at x=0, and an x-intercept at x=1. Its vertical scaling will depend on the base of the logarithm. Like any function, it can be translated and scaled horizontally and vertically.
__
Additional comment
In the field of complex numbers, the log function is defined for any non-zero number. For example, ln(-1) = πi.
The range is all real numbers.

rolling a number cube, tossing a coin and choosing a card from cards marked A and B
a. 24
C.
18
b. 12
d. 6
HELP PLEASE
Answer:
a. 24
Step-by-step explanation:
Rolling a number cube: 6 outcomes
tossing a coin: 2 outcomes
At this point, we have 6 x 2 = 12 outcomes, because each of the 6 numbers on the cube can each have a heads or tails outcome
Choosing card A or card B gives us 2 more outcomes for each of the 12 outcomes we have so far.
12 x 2 = 24
What is the value of S unit?
Triangle ABD is a right-angled triangle. The value of s which is the hypotenuse of the triangle ABD is 17 units.
What is triangle?A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. Triangle ABC denotes a triangle with vertices A, B, and C. In Euclidean geometry, any three non-collinear points define a unique triangle and, by extension, a unique plane. Triangles are three-sided polygons with three vertices. The angles of the triangle are formed by connecting the three sides end to end at a point. The total of the triangle's three angles equals 180 degrees.
Here,
Given information:
From the given figure, the following information can be extracted:
Triangle ABD is a right-angled triangle.
Base AB is 8 units, Height BD is 15 units.
s is the hypotenuse of the triangle ABD.
Use the Pythagoras theorem to solve for the value of s or AD,
AD²=AB²+BD²
s²=8²+15²
s²=289
s=17 units
Therefore, the value of s which is the hypotenuse of the triangle ABD is 17 units.

P(graduate) = Total graduates / Total studentsP(graduate) = 2610/10730*100% = 24% (rounded)The probability that a student selected at random is a graduate student is 31%.
What is probability?The probability of an event happening is represented by a number. The ratio of favourable outcomes to all outcomes is how probability is defined.
The total number of students is 6101, out of which 1879 are graduate students. Therefore, the probability that a student selected at random is a graduate student is:
P(graduate student) = number of graduate students / total number of students
P = 1879 / 6101
P = 0.3078
Therefore, the probability that a student selected at random is a graduate student is 31%.

The total surface area of the prism below is 456 square centimeters. What is the value of the x, height of the prisim?
*see attachment for the figure
Answer:
x = 17 cm
Step-by-step explanation:
Total surface area of triangular prism = bh + L(s1 + s2 + s3)
Where,
Total surface area = 456 cm²
b = 8 cm
h = 6 cm
s1 = √(8² + 6²) = 10 cm (pythagorean theorem)
s2 = 8 cm
s3 = 6 cm
L = x
Plug in the values
465 = 8*6 + x(10 + 8 + 6)
465 = 48 + x(24)
465 - 48 = 24x
417 = 24x
417/24 = x
17.375 = x
x = 17 cm (approximated)

A recipe ue 1/3 cup of flour and 1/8 cup of ugar. How much flour and ugar doe the recipe ue altogether
Altogether, the recipe uses 1/2 cup of flour and 1/8 cup of sugar.
What is altogether?Altogether in math refers to the sum of two or more numbers or values. It is a way of combining two or more items to obtain a total. In math, the term "altogether" is used to denote the sum of all the individual items, as opposed to all of them considered as one. For example, the sum of the numbers 2, 4, and 6 is 12, which is the "altogether" in math.
To calculate this, we must convert the fractions into decimals and then add them together.
The 1/3 cup of flour can be converted to 0.33 cup, and the 1/8 cup of sugar can be converted to 0.125 cup.
When added together, they equal 0.455 cup, or 1/2 cup. Therefore, the recipe uses a total of 1/2 cup of flour and 1/8 cup of sugar.

Daija is creating a budget, and evaluating his purchases over the last month. Consider the following code segment which attempts to find the sum of all purchases made in the last month, stored in purchased List. N ← 1 sum ← 0 REPEAT UNTIL () { sum ← sum + purchase List[n] n ← n + 1 } What code can replace missing code to assign the total of all values in purchase List to sum
The missing code that can replace to assign the total of all values in purchase List to sum, is: REPEAT UNTIL (n > purchaseList.length)
What is syntax of REPEAT UNTIL?The syntax for a REPEAT UNTIL loop in most programming languages is as follows:
REPEAT {
// code to be executed
} UNTIL (condition)
or
DO {
// code to be executed
} UNTIL (condition)
What is looping?Looping is a programming construct that allows a certain block of code to be executed repeatedly. The two main types of loops are for loops and while loops.
A for loop is used to execute a block of code a specified number of times. It typically starts with a variable initialization, then a condition is checked, and if the condition is true, the code block inside the loop is executed, and then the variable is updated.
The missing code that can replace the empty parentheses in the REPEAT UNTIL statement to assign the total of all values in purchase List to sum, is:
REPEAT UNTIL (n > purchaseList.length)
This means that the loop will continue to execute until the value of n is greater than the length of the purchaseList. In each iteration, the value of purchaseList[n] is added to the sum, and then n is incremented by 1. So, this loop will iterate through all the elements in the purchaseList, adding each one to the sum, until it reaches the end of the list. This will give the total sum of all purchases made in the last month.

Answer:the pair of simultanous equations that model Andy's and Ron's ages are
3A-2R=6----Equation 1
R-A =2----Equation 2
Andy is 10 Years and Ron is 12 years
Step-by-step explanation:
Andy's age is represented as A
and Ron';s age is represented as R
Now if Andy multiplies his own age by 3. He then subtracts twice Ron's age. The answer is 6 can be expressed mathematically as
3A-2R=6
And if Ron subtracts his age from Andy's age. The answer is −2 can be expressed as
R-A =2
Therefore the pair of simultaneous equations that model Andy's and Ron's ages are
3A-2R=6----Equation 1
R-A =2----Equation 2
Solving becomes
3A-2R=6----Equation 1
R-A =2----Equation 2
Make R subject formulae in equation 2
R =2+A
Putting R =2+A in equation 1
3A-2(2+A)=6
3A -4-2A =6
A-4=6
A=6+4=10
From eqn 2,
R-A =2
R-10 =2

Answer:
3/50
Step-by-step explanation:
There are 5 + 4 + 2 + 6 + 3 = 20 marbles in the bag
P(draw a black) = 6/20 = 3/10
If the black marble is replaced, then there are 20 marbles in the bag again.
P(draw a blue) = 4/20 = 1/5
P(draw a black and blue with replacement) = (3/10)(1/5) = 3/50

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
For example, 3x – 5 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 7. There are different types of equations like linear, quadratic, cubic, etc.
Let's consider Almonds be a and Peanuts be p.
from given conditions,
a + p = 20
and 5.95 a + 2.95 p = 4(20)
5.95 a + 2.95 p = 80
take, a = 20 - p
5.95 (20 - p) + 2.95 p = 80
119 - 5.95 p + 2.95 p =80
119 - 3 p = 80
3p = 39
p = 39/3

If each score is doubled, and then 5 is subtracted from that result, then the mean and standard deviation will be 115 and 36 respectively.
What will be the mean and standard deviation?A huge group of test results has a mean of 60 and a standard deviation of 18. If each score is doubled and then 5 is deducted from the result, the mean and standard deviation are “ mean = 115; standard deviation = 36”. Mean = 2 x 60 -5 = 120 -5 = 115
2 x 18 = 36 standard deviation
The mean is the average and is calculated as the sum of all the results from the example divided by the total number of events.
The standard deviation (SD) is a statistic used to assess the degree of variation or dispersion in a set of data values.
A low standard deviation indicates that the information points slant toward being near the mean of the set, whereas an exclusive expectation deviation or a high standard deviation indicates that the information points tilt toward being near the mean of the set.
