(Please answer ASAP) A bag contains three red marbles, five green marbles, and two blue marbles.
a. What is the probability of getting a red marble?
b. What is the probability of NOT getting a red marble?
Answers
Answer:
a. 3/10
b. 7/10
Step-by-step explanation:
a. Total number of marbles = 10
Number of red marbles = 3
Probability = Number of outcomes/ Total number of outcomes
= 3/10
b. Total number of marbles = 10
Number of red marbles = 3
Number of marbles excluding the red marbles
= 10 - 3 = 7
Probability = Number of outcomes/ Total number of outcomes
= 7/10
n the rhombus m ∠ 1 = 160 ° . What are m ∠ 2 and m ∠ 3 ? The diagram is not drawn to scale
Answers
Answer:
∠ 2 = 160° , ∠ 3 = 10°
Step-by-step explanation:
The opposite angles of a rhombus are congruent , then
∠ 2 = ∠ 1 = 160°
The triangle has 2 congruent sides and is isosceles with base angles being congruent , then
∠ 3 = [tex]\frac{180-160}{2}[/tex] = [tex]\frac{20}{2}[/tex] = 10°
Answer:
m∠3 = 10° || m∠2 = 160°
Step-by-step explanation:
if m∠1 = 160°
then m∠2 = 160°
The triangle is isosceles.
therefore
m∠3 + m∠3 + 160° = 180°
2 m∠3 = 180° - 160°
2 m∠3 = 20°
m∠3 = 10°
Using derivatives+optimization, find the dimensions of the rectangle of largest area that can be inscribed in an equilateral triangle of side 12.
Answers
Check the picture below atop.
we know is an equilateral triangle, meaning that all its interior angles are 60°, and thus if we run a line from the top vertex as you see there, we end up with a 30-60-90 triangle, either way there's an equation to get its height, and anyhow the altitude of it is 6√3.
As the rectangle moves up and down the triangle, with the rectangle having a width of "w" and a length of "L", the triangle that it forms above itself is a triangle, always with a base of "L" and a height of 6√3 - w.
BTW we laid the rectangle as you see on the bottom side, but laying it anywhere else it'd have ended up in the same arrangement.
well, with the bottom of the rectangle beign parallel to that of the side of the circumscribing triangle, the small upper triangle is similar to the containing triangle by AAA, and since we have similar triangles, we can say that.
[tex]\cfrac{6\sqrt{3}}{12}=\cfrac{6\sqrt{3}-w}{L}\implies \cfrac{\sqrt{3}}{2}=\cfrac{6\sqrt{3}-w}{L}\implies L\sqrt{3}=12\sqrt{3}-2w \\\\\\ L=\cfrac{12\sqrt{3}-2w}{\sqrt{3}}\implies L=12-\cfrac{2w}{\sqrt{3}}\implies L=2\left(6-\cfrac{w}{\sqrt{3}} \right) \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{Area of the rectangle}}{A=wL\implies A(w)=w\cdot 2\left(6-\cfrac{w}{\sqrt{3}} \right)}\implies A(w)=2\left(6w-\cfrac{w^2}{\sqrt{3}} \right)[/tex]
[tex]\cfrac{dA}{dw}=2\left(6-\cfrac{2w}{\sqrt{3}} \right)\implies \cfrac{dA}{dw}=4\left(3-\cfrac{w}{\sqrt{3}} \right) \\\\[-0.35em] ~\dotfill\\\\ 0=4\left(3-\cfrac{w}{\sqrt{3}} \right)\implies \boxed{w=3\sqrt{3}}[/tex]
hmmm the way I usually run a 1st derivative test is, by using the critical point and slicing from it just a tiny bit, like say 3√3 - 0.000000001 to check the region on the left and then 3√3 + 0.000000001 to check the region on the right.
Check the picture at the bottom, the 1st derivative test more or less gives us those values, positive on the left-side and negative on the right-side, meaning as you can see in the arrows, is a maximum at that point.
[tex]\stackrel{\textit{we know that}}{L=2\left(6-\cfrac{w}{\sqrt{3}} \right)}\implies L=2\left(6-\cfrac{3\sqrt{3}}{\sqrt{3}} \right)\implies \boxed{L=6}[/tex]

Answers
Answer:
The workout ratio of the online sales to shop sales is 1:3.Graph 0.04x+0.02y=0.08.
Answers
Answer:
see below
Step-by-step explanation:
let's convert it into slope intercept form first as it will get rid of the decimals. so we must get it to follow the form of y = mx + b.
so we must isolate the y variable:
- subtract 0.04x from both sides
- now we have 0.02y = 0.08 - 0.04x, and to follow the form this can also be 0.02y = -0.04x + 0.08
- divide both sides by 0.02
- now we have y = -2x + 4, so we know the slope is -2
now lets find the intercepts:
y intercept => set x=0
y = -2(0) + 4
y = 4
so we have (0,4)
x intercept => set y=0
0 = -2x + 4
-4 = -2x
x= 2
now we have (2,0)
graph it:
with two points (the intercepts) and the slope we can find a graph that looks like this

x ≈ 229.8
Step-by-step explanation:
using the cosine ratio in the right triangle
cos72° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{LM}{KM}[/tex] = [tex]\frac{71}{x}[/tex] ( multiply both sides by x )
x × cos72° = 71 ( divide both sides by cos72° )

Put the following equation of a line into slope-intercept form, simplifying all fractions.
12x-20y= 60
Answers
Answer:
[tex]y=\frac{3}{5} x-3[/tex]
Step-by-step explanation:
Slope-intercept form: y = mx+ b
m = slope
b = y-intercept
Rearrange the equation:
[tex]-20y=-12x+60[/tex]
Divide each side by -20:
[tex]\frac{-20y}{-20} =\frac{-12x}{-20} +\frac{60}{-20}[/tex]
[tex]y=\frac{3}{5} x-3[/tex]
[tex]y=\frac{3}{5} x-3[/tex] is your simplified, slope-intercept form equation.

Write an exponential function to represent a person consuming a bag of candy in which the initial value in an is 175 pieces and the rate of decay is 20%.
Answers
We will see that the exponential decay function is:
f(x) = 175*(0.8)^x
How to find the exponential decay?
The general exponential decay is:
f(x) = A*(1- r)^x
Where:
A is the initial value.r is the rate of decay in decimal form.x is the variable, in this case is the time.Here we know that the initial value is 175, and the rate of decay is 20%. To get this in decimal form, we just divide it by 100%.
20%/100% = 0.2
Replacing that in the exponential function, we get:
f(x) = 175*(1 - 0.2)^x
f(x) = 175*(0.8)^x
