Incomplete question:
A fair die is rolled one. What is P(roll less than 4)? If necessary, round your answer to 2 decimal places.
Answer:
P(roll less than 4) = 0.50
Step-by-step explanation:
First, we need to list the sample space.
[tex]S = \{1,2,3,4,5,6\}[/tex]
From the above, we have that:
[tex]n(S) = 6[/tex] i.e. total rolls
Represent Rolls less than 4 with L4; So,
[tex]L4 = \{1,2,3\}[/tex]
[tex]n(L4) = 3[/tex] i.e. number of rolls less than 4
The required probability is calculated as:
[tex]Probability = \frac{n(LA)}{n(S)}[/tex]
[tex]Probability = \frac{3}{6}[/tex]
[tex]Probability = 0.50[/tex]
Answer: 0.50

|2h+7|=4. Solve for h
Answer:
h=-3/2 and h=-11/2
Step-by-step explanation:
There are two solutions for h it is:
2h+7=4 and 2h+7=-4
Lets do 2h+7=4
2h=-3 (Move the 7 to the other side)
h=-3/2 (Answer)
Lets do 2h+7=-4
2h=-11 (Move the 7 to the other side)
h=-11/2 (Answer)
Answer:
h=-3/2, -11/2
Step-by-step explanation:
There are two solutions for h
2h+7=4 and 2h+7=-4
2h+7=4:
Move the 7 to the other side to eliminate the 7 on the left side: 2h=-3
divide: h=-3/2
h=-3/2
2h+7=-4:
Move the 7 to the other side to eliminate the 7 on the left side: 2h=-11
divide: h=-11/2
h=-11/2

"The electric bill reflected a monthly fee of $42.00 as well as a kilowatt per hour charge of $0.0953 for electricity used. Which function determines the amount of electricity used based on the total bill cost? Group of answer choices"
Given data
monthly fee= $42
kilowatt per hour charge=$0.0953
let the number of hours be =x
let the expression be patterned after the model\
y=mx
here y=42
m=0.0953
We want to find x, the amount of electricity used
42=0.0953x
divide both sides by 0.0953 we have
42/0.0953=x
x=440.71

Find the points at which the tangent line is horizontal for the given interval. F(x)=cosx-sinx [0,2pi]
Answer:
[tex]x=\{\frac{3\pi}{4}, \frac{7\pi}{4}\}[/tex]
Step-by-step explanation:
For the tangent line to be horizontal, the derivative of the function at that point must be 0.
Thus, let’s first take the derivative of our function:
[tex]f ^\prime(x)=\frac{d}{dx}[\cos(x)-\sin(x)][/tex]
Differentiate:
[tex]f^\prime(x)=-\sin(x)-\cos(x)[/tex]
Now, let’s set our derivative equal to 0:
[tex]0=-\sin(x)-\cos(x)[/tex]
Let’s multiply everything by a negative:
[tex]0=\sin(x)+\cos(x)[/tex]
To solve for x, we can subtract sin(x) from both sides. This gives us:
[tex]\cos(x)=-\sin(x)[/tex]
Now, we can refer to the unit circle. First, remember that the only points for which cosine is equal to sine is at the π/4 points. That is, π/4, 3π/4, 5π/4 or 7π/4.
However, cosine is equal to negative sine. The only two quadrants for which cosine and sine are the same but also have opposite signs is QII and QIV.
Therefore, our answers are 3π/4 and 7π/4.
A business orders 215 flowers for their employees on Valentine's Day. Roses cost $3.00 each, carnations cost $1.00 each, and lilies cost $2.00 each. There are 15 more lilies than roses. The total of the order came to $410.00. How many of each type of flower were ordered?
Let, number of roses, carnations and lilies are x, y and z respectively.
So,
x + y + z = 215 ....1 )
It is given that total cost is $410.00 :
3x + y + 2z = 410 ....2 )
Also, there are 15 more lilies than roses.
z = x + 15 ....3 )
Putting value of z in eq 1 and 2 , we get :
x + y + x + 15 = 215
2x + y = 200 ....4 )
3x + y + 2( x + 15 ) = 410
5x + y = 380 ....5 )
Solving equation 4 and 5, we get :
3x = 180
x = 60
z = 60 + 15 = 75
y = 215 - 60 - 75 = 80
Therefore, number of roses, carnations and lilies are 60, 80 and 75 respectively.
Hence, this is the required solution.
Thereisalinewhoseslopeis0andwhose y -intercept is –6 . What isitsequationin slope -intercept form? Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
The equation of a line with slope 0 and y-intercept -6 in slope-intercept form is [tex]y = -6[/tex].
Step-by-step explanation:
From Analytical Geometry we know that equation of the line in slope-intercept form is represented by:
[tex]y = m\cdot x + b[/tex] (Eq. 1)
Where:
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
[tex]m[/tex] - Slope, dimensionless.
[tex]b[/tex] - y-Intercept, dimensionless.
If we know that [tex]m = 0[/tex] and [tex]b = -6[/tex], then the equation of the line is:
[tex]y = 0\cdot x +(-6)[/tex]
[tex]y = -6[/tex]
The equation of a line with slope 0 and y-intercept -6 in slope-intercept form is [tex]y = -6[/tex].

Put the following equation of a line into slope-intercept form, simplifying all fractions. 20x-12y= 20x−12y= \,\,-108 −108
Answer:
well shiet
Step-by-step explanation:
y=5/3x+9 is the slope intercept form of the equation of line 20x-12y=-108
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The given equation is 20x-12y=-108
We need to write this equation in the form of slope intercept form.
To do this we have to isolate the y term
-12y=-108-20x
Now divide both sides by 12 and multiply with minus.
y=9+20/12x
y=9+5/3x
y=5/3x+9 is the required equation.
Hence, y=5/3x+9 is the slope intercept form of the equation of line 20x-12y=-108
