Answer:
13
Step-by-step explanation:
The number is 1 more than the least common multiple of 3 and 4. That multiple is 12, so the number of stairs is 12+1 = 13.
Martha's school staircase has 13 steps, minimum.
_____
Additional comment
The real minimum is 1, not 13. We assume that we're interested in the non-trivial solution. (In a public building, staircases between floors often have 14 steps. 13 steps might attract the attention of those who are superstitious.)

the probability that a particular song is played is 76%. What is the probability that this song will be played on exactly 2 days out of 6 days? Round your answer to the near
Answer:
0.0287
Step-by-step explanation:
Using the binomial probability relation :
p = 0.76
q = 1 - p = 1 - 0.76 = 0.24
P(x = x) = nCx * p^x * q^(n-x)
P(x = 2) = 6C2 * 0.76^2 * 0.24^4
P(x = 2) = 15 * 0.76^2 * 0.24^4
P(x = 2) = 0.02874507264
P(x = 2) = 0.0287
Solve for x

Answer:
x=25
Let's solve your equation step-by-step.
3x+18=93
Step 1: Subtract 18 from both sides.
3x+18−18=93−18
3x=75
Step 2: Divide both sides by 3.
3x/ 3 = 75/ 3
x=25

Consider function f and its graph.
f(x) = 1/2sin(2x)
what is the amplitude of this function? a. 1 b. pi/2 c. pi/4 d. 1/2
Answer:
1/2
Step-by-step explanation:
The amplitude is 1/2.
The amplitude of the sin function is 1/2.
We have given the function
f(x) = 1/2sin(2x)
What is the general equation of the sin wave?y(x,t)=Asin(kx−ωt+ϕ)
A is the amplitude of the wave.
ω is the wave's angular frequency.
k is the wavenumber
ϕ is the phase of the sine wave
Compare the given equation with the general formula of the sin wave.
Therefore we get,
y(x,t)=f(x)
A=1/2
Therefore the amplitude of the sin function is 1/2.

A random sample of 10 employees of a company was selected to estimate the mean one-way commute time for all employees at the company. The mean and standard deviation of the sample were 38 minutes and 6 minutes, respectively. Assuming all conditions for inference are met.
Required:
What is the margin of error, in minutes, for a 95 percent confidence interval for the population mean one-way commute time?
Answer:
The margin of error is of 4.22 minutes.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 10 - 1 = 9
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 9 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.2622
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}}[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
We have that [tex]s = 6, n = 10[/tex]. So
[tex]M = T\frac{s}{\sqrt{n}} = 2.2622\frac{6}{\sqrt{10}} = 4.22[/tex]
The margin of error is of 4.22 minutes.

Find the measure of each numbered angle or are.
Answer:
<2 = 133degrees
<1 = 135degrees
Step-by-step explanation:
From the diagram, the angle <2 and 47 are supplementary, hence;
<2 + 47 = 180
<2 = 180 - 47
<2 = 133degrees
To get <1;
47 = 1/2(<1 - 41)
47 * 2 = (<1 - 41)
94 = <1 - 41
<1 = 94 + 41
<1 = 135degrees

Answer:
-0.75
Step-by-step explanation:
If the difference is common, it is the difference of any pair of adjacent y-values (for sequential x-values).

2 * 5/2 = 5 * 2/8
5x = 5/4
x = 1/4
Which statement describes whether the function is continuous at x = –2?
The function is continuous at x = –2 because f(–2) exists.
The function is continuous at x = –2 because Limit as x approaches negative 2 plus f(x) = f(–2).
The function is not continuous at x = –2 because Limit as x approaches negative 2 f(x) ≠ f(–2).
The function is not continuous at x = –2 because Limit as x approaches negative 2 f(x) does not exist.
Answer: D. The function is not continuous at x = –2 because Limit as x approaches negative 2 f(x) does not exist.

determine the roots of the quadratic below
Hi there! In the quadratic function, there are three types of solutions.
two real rootsone real rootno real roots (complex roots)To find the solution by graph, what we have to do is to see if a graph intersects a x-axis plane or not. If it doesn't, that means a graph clearly doesn't have solutions.
As we see in the picture, the graph of function doesn't intersect x-axis and thus there are no real roots.
Answer
No rootsWe need to tell the roots of the equation of graph plotted above . The condition of roots for a quadratic equation is ,
On real root if the graph touches the X axis at one point .Two real distinct roots , if the graph cuts x axis at two points. Complex roots / Imaginary roots if it don't intersect X axis.Here we can see that the graph doesn't cuts x axis. So , the equation don't have any roots.
