6 minutes longer than Laura.
Ken sang 6 minutes longer than Laura.
Answers
The phrase “6 minutes longer than Laura” is an expression,
What is an expression?Expression in mathematics is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We are given that;
6 minutes longer than Laura and Ken sang 6 minutes longer than Laura.
Now,
Because it does not have an equal sign. It can be written as L + 6, where L is the number of minutes that Laura sang.
The sentence “Ken sang 6 minutes longer than Laura” is a situation that can be modeled by an equation, because it involves a relationship between two quantities. It can be written as K = L + 6, where K is the number of minutes that Ken sang and L is the number of minutes that Laura sang.
Therefore, by the given statement answer will be expression.

Question 10 of 10
If a sample mean is 37, which of the following is most likely the range of
possible values that best describes an estimate for the population mean?
O A. (28,36)
B. (32, 42)
C. (34, 42)
D. (30,38)
Answers
If a sample mean is 37, (32, 42) is most likely the range of possible values that best describes an estimate for the population mean. The correct option is C.
What is mean?In math, a mean is the average of a data set, which is calculated by adding all of the numbers together and then dividing the sum of the numbers by the number of numbers.
Assuming a moderate sample size (e.g., n = 30) and a typical population standard deviation (e.g., σ = 10), the SEM can be estimated to be approximately 2.
Using this estimate, the range of possible values for the population mean can be calculated as:
37 - x = 33
37 + 2 * 2 = 41
Therefore, the most likely range of possible values for the population mean is option C.

A fireman leaned a 28 foot ladder against a building. If he placed the ladder 14 feet from the base of the building, what angle is formed between the ladder and the ground
Answers
Answer:
The ladder makes an angle of 60 degree from the ground.
Step-by-step explanation:
Length of the ladder, L = 28 feet
distance of ladder, d = 14 feet
Let the angle formed with the ground is A.
According to the trigonometry
[tex]\cos A =\frac{d}{L}[/tex]
[tex]\cos A =\frac{14}{28}[/tex]
cos A = 0.5
A = 60 degree
What is the perimeter,in centimeters of triangle QRS?
Answers
Answer: 60
Step-by-step explanation:
You have to use Pythagorean Theorem because the other side is not listed of the triangle
Pythagorean Theorem: a² + b² = c²
a² + 20² = 25²
a² + 400 = 625
625-400 = a²
a² = 225
Find the square root of 225 to find the missing length
[tex]\sqrt{225}[/tex] = 15 (this is the missing length for QS
To find the perimeter, add all the sides...
15 + 20 +25 = 60

c. x=[tex]\frac{13}{8}[/tex]
d. x=[tex]\frac{25}{16}[/tex]
Answers
Answer:
C
Step-by-step explanation:
I think
The solution to the equation above using three iterations of successive approximation is x = 25/16
What is an equation?An equation is an expression that is represented by the equality or equal to sign i.e "="
The equation is given as:
[tex]5^{-x} + 7 =2x + 4[/tex]
Equate to 0
[tex]5^{-x} + 7 -2x - 4 = 0[/tex]
Express as a function
[tex]f(x) = 5^{-x} + 7 -2x - 4[/tex]
The equation has a solution when f(x) = 0.
From the graph, we have:
x = 1.5
So, we have:
[tex]f(1.5) = 5^{-1.5} + 7 -2*1.5 - 4[/tex]
Evaluate
f(1.5) = 0.089
Set x to 1.52 to determine a closer value of f(x) to 0.
[tex]f(1.52) = 5^{-1.52} + 7 -2*1.52 - 4[/tex]
Evaluate
f(1.52) = 0.047
Set x to 1.54 to determine a closer value of f(x) to 0.
[tex]f(1.54) = 5^{-1.54} + 7 -2*1.54 - 4[/tex]
Evaluate
f(1.54) = 0.004
Notice that 0.004 is closer to 0 than 0.047 and 0.089
From the list of options, the closest value to 1.54 is 25/16
Hence, the solution to the equation above using three iterations of successive approximation is x = 25/16

Step-by-step explanation:
To solve this problem, use the trigonometric ratios. The trigonometric ratios for a right triangle (a triangle with a right angle are the following).
[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}[/tex]
In this case, one is given the hypotenuse (the side opposite the right angle) and one is asked to find the side adjacent to the given angle. Therefore, it would make the most sense to use the trigonometric ratio of cosine ([tex]cos[/tex]).
[tex]cos(\theta)=\frac{adjacent}{hypotenuse}[/tex]
Substitute,
[tex]cos(47)=\frac{x}{3}[/tex]

Eight friends want to play enough games of chess to be sure everyone plays everyone else. How many games will they have to play?
Answers
The number of games, the friends have to play is an illustration of combination.
They have to play 28 games to ensure that they all play
Given
[tex]n = 8[/tex] --- number of friends
[tex]r = 2[/tex] --- only two friends can play at a time
For everyone else to play, we will make use of the following combination formula;
[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]
So, we have:
[tex]^8C_2 = \frac{8!}{(8 - 2)!2!}[/tex]
[tex]^8C_2 = \frac{8!}{6!2!}[/tex]
Expand
[tex]^8C_2 = \frac{8 \times 7 \times 6!}{6! \times 2 \times 1}[/tex]
[tex]^8C_2 = \frac{8 \times 7}{2 \times 1}[/tex]
[tex]^8C_2 = 4 \times 7[/tex]
[tex]^8C_2 = 28[/tex]
Hence, the 8 friends have to play 28 games to ensure that everyone else plays
