Step-by-step explanation:
Out of a class of 150 students, two-fifths opted for German classes and one-third opted for Italian classes. The remaining opted for French. What fraction opted for French?
Fraction of students that opted for French = [tex]\frac{4}{15}[/tex]
The total number of students = 150
Fraction of students that opted for German = [tex]\frac{2}{5}[/tex]
Fraction of students that opted for Italian = [tex]\frac{1}{3}[/tex]
Fraction of students that opted for French = 1 - Fraction of students that opted for German - Fraction of students that opted for Italian
Fraction of students that opted for French = [tex]1-\frac{2}{5} - \frac{1}{3}[/tex]
Fraction of students that opted for French = [tex]\frac{15-6-5}{15}[/tex]
Fraction of students that opted for French = [tex]\frac{4}{15}[/tex]

Use the graph to determine the domain and range. Then state whether the relation is a function.
What is the domain of the function?
Answer:
[-2, 4]
Step-by-step explanation:
The domain of a function is the set of all x-values a relation could possibly take on to have an output. This is represented by in the graph by having the line correspond to the x-value. From the graph shown we can see that x-values from -2 to 4 have a line corresponding to them, and the dots are closed meaning it is inclusive. This would be written as: [-2, 4]
An inverted conical water tank with a height of 12 ft and a radius of 3 ft is drained through a hole in the vertex. If the water level drops at a rate of 1 ft/min, at what rate is water (in ft3/min) draining from the tank when the water depth is 8 ft
Answer:
dhdt≃0.283ft3s
Step-by-step explanation:
dhdt≃0.283ft3s
The draining from the tank when the water depth is 8 ft will be negative 1/π feet per minute.
What is differentiation?The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.
An inverted conical water tank with a height of 12 ft and a radius of 3 ft is drained through a hole in the vertex. If the water level drops at a rate of 1 ft/min.
[tex]\rm \dfrac{dV}{dt} = -1 \ ft/min[/tex]
The volume of the cone is given as,
V = (1/3) πr²h
The relation between r and h is given as,
r / h = 3 / 12
r = h / 4
Then the volume is written as,
V = (1/3) π (h/4)² × h
V = (π / 48) h³
Differentiate the volume with respect to time. Then we have
(dV)/(dt) = (π/48) x 3h² x (dh / dt)
- 1 = (π/48) x 3(4)² (dh / dt)
- 1/π = dh / dt
The draining from the tank when the water depth is 8 ft will be negative 1/π feet per minute.

What is the slope of the line passing through the points A and B, as shown on the graph below?
A)-3
B) -1/3
C) 1/3
D) 3
Answer:
-1/3
Step-by-step explanation:
We can start by finding the coordinates of 2 points, A and B. A is (-3, 8) and B is (3, 6). Now, we can use [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] to find the slope, and if you plug in those points you get (8 - 6)/(-3 - 3) = 2/(-6) = -1/3.

a trader bought a stock of cabbage for 1200 rupees. after removing the spoiled stock, he had a loss of 8%. what is the amount he got by selling the cabbage
An item that originally cost $100 is decreased by 8%. The reduced price is then increased by 8%.
The resulting price is_
between $92 and $100
$92
$100
more than $100
Answer:
$99.36
Step-by-step explanation:
Hii!
So first, you need to find 8% of $100. You can do that by 100 x 0.08 which is $8. This means that the cost is reduced by $8 so 100 - 8 = $92
The reduced price is $92.
Then if we increase the reduced price by 8%, we will find the resulting price. Agani we find 8% of $92 which is 0.08 x 92 = 7.36. This means we have to increase the cost of $92 by this amount. $92 + 7.36 = $99.36
Hope this helps :)
Answer: 99.36
Step-by-step explanation:
because when you add 430 to 0 it makes 492/5 x 40 then x goes into m 4302 times there for its 99.36 USD.

Answer:
18 cm²
Step-by-step explanation:
All sides of a rhombus are the same length (as shown by the markings), so one side is 1/4 of the perimeter:
(24 cm)/4 = 6 cm . . . . side length
As with all parallelograms, the area is the product of the side length and the height perpendicular to that side:
A = (6 cm)(3 cm) = 18 cm²
It has an area of 18 cm².
You and a group of friends are going to a five-day outdoor music festival during spring break. You hope it does not rain during
the festival, but the weather forecast says there is a 50% chance of rain on the first day, a 25% chance of rain on the second day, a
20% chance of rain on the third day, 5% chance of rain on the fourth day, and a 10% chance of rain on the fifth day.
Assume these probabilities are independent of whether it rained on the previous day or not.
What is the probability that it does not rain during the entire festival?
%
(Round to 2 decimal places)
Answer:
Below in bold
Step-by-step explanation:
The probability that it doesn't rain is 1 - probability it does ( Prob written as a fraction). So for the first day Probability of not raining = 1 - 0.50 = 0.50.
So the probability of it not raining the entire festival
= 0.5 * 0.75 * 0.80 * 0.95 * 0.90
= 0.2565
or 25.65%

Use an equation to find the value of k
so that the line passing through (−4,k)
and (6,−7)
has a slope of −15
Answer: k=143
Step-by-step explanation:
Let's start with the standard form of a linear equation: y = mx + b, where m ios the slope and b is trhe y-intercept (the value of y when x=0). We know the slope, so:
y = -15x + b
We can find the y-intercept, b, by using the one given point (6,-7) in the equation and solve for b:
y = -15x + b
-7 = -15(6) + b
-7 = -90+b
b = 83
The equation is y = -15x + 83
Use the x value of (-4,k) to find y, which will be k.
y = -15x + 83
y = -15(-4) + 83
y = 60 + 93
y = 143
k is 143
how can i answer 6x-3y=-6
Answer:
Step-by-step explanation:
Rewrite in slope-intercept form.
The slope-intercept form is
y = m x + b , where m is the slope and b is the y-intercept. y = m x + b
Reorder 2 and 2 x . y = 2 x + 2
Use the slope-intercept form to find the slope and y-intercept.
Slope:
2
y-intercept:
2
