Answer:
1) P(none are red) = 51.2%
2) P(third one is the first one that is yellow) = 12.8%
Step-by-step explanation:
We are given;
P(Yellow) = 20% = 0.2
P(red) = 20% = 0.2
P(Orange) = 10% = 0.1
P(Blue) = 10% = 0.1
P(green) = 10% = 0.1
P(brown) = 30% = 0.3
1) Probability that one is not red is;
P(one not red) = 1 - P(red)
P(one not red) = 1 - 0.2
P(one not red) = 0.8
Since 3 are selected, we will apply multiplication rule for independent events to get;
P(none are red) = 0.8 × 0.8 × 0.8
P(none are red) = 0.512
P(none are red) = 51.2%
2) To find the probability, that the third one is the first one that is yellow, we will use multiplication rule for independent events to get;
P(third one is the first one that is yellow)
= (1 - P(Yellow)) × (1 - P(Yellow)) × P(Yellow)
P(third one is the first one that is yellow) = (1 - 0.2) × (1 - 0.2) × 0.2
P(third one is the first one that is yellow) = 0.128
P(third one is the first one that is yellow) = 12.8%
Some students were asked to pick their favourite Action Hero.
3/5 chose Batman, 20% chose Hulk and the rest chose Iron Man.
.
Write the ratio of Batman: Hulk: Iron Man in Simplest form.
Select one:
a. 6:2:2
b. 60: 20:20
c. 3:1:1
Answer:
a
Step-by-step explanation:
First convert 3/5 to a percentage.
3/5 is 60% and 20% of the students chose Hulk. That leaves 20% who chose Iron Man. The simplest form of 60:20:20 is 6:2:2.

y=x/4+1/2 find the x and y Pls help asap
Answer:
y = 1/4x + 1/2 and x = -2 +4y
Step-by-step explanation:
Solving it in a way that x/4 is a fraction and not division so you would make that 1/4x. y = x/4 +1/2 x/4 is 1/4x so then you subtract 1/2 from both sides to get y - 1/2 = 1/4x. You can then divide 1/4 on both sides. -1/2 divided by 1/4 is -2 and 1/4y. This will get your answer of x = 1/4y -2 for x. Y is just 1/4x + 1/2

Answer:
[tex]d=10[/tex]
Step-by-step explanation:
Pythagorean theorem:
[tex]d^2+d^2=10\sqrt{2}^2,\\2d^2=200,\\d^2=100,\\d=\boxed{10}[/tex]
Alternative:
[tex]\cos 45^{\circ}=\frac{d}{10\sqrt{2}},\\\frac{\sqrt{2}}{2}=\frac{d}{10\sqrt{2}},\\2d=10\sqrt{2}\cdot \sqrt{2},\\2d=20,\\d=\boxed{10}[/tex]
Alternative (derived from the Pythagorean theorem):
All 45-45-90 triangles have side lengths [tex]x-x-x\sqrt{2}[/tex], where [tex]x\sqrt{2}[/tex] is the hypotenuse. Since this triangle's hypotenuse is [tex]10\sqrt{2}[/tex], its sides are [tex]10-10-10\sqrt{2}[/tex].
Translate the expression: 3 times the difference between 7 and
g is 90
Answer:
3(7-g)=90
You multiply the expression by 3. The difference means to subtract two values. The whole equation equals 90.

Step-by-step explanation:
i think this is correct, I'm not 100% sure that it is because the question was a little confusing.
ANSWER:
It would be 6x^3.
PRIOR NOTE:
For this question, it's slightly unclear regarding the formatting with it, but in here I'm going to assume that you've asked what is:
-2x * 3x * -x
when simplified. If it was something else, then the final answer would be different.
BACKGROUND:
To start, when multiplying two terms together, the variable will become squared or to the second power. For example:
2x * 2x = 4x^2
PROCESS:
With this question, it is asking for -2x * 3x * -x, though lets just start with the -2x * 3x part:
-2x * 3x = -6x^2
Now, finishing it off with the * -x part.
-6x^2 * -x = 6x^3
It goes to the third power, because now you have multiplied 3 x's together. The answer is also now positive since a negative * a negative = a positive.
With this, the final answer is 6x^3.

A capacitor holds a 8.89 x 10-7 C
charge when 32.0 V are applied to
it. What is its capacitance?
Answer:2.77*10^-8
Step-by-step explanation:
8.89*10^-7/32.0
The capacitance of the capacitor is approximately 2.78 x 10⁻⁹ Farads (F).
The capacitance of a capacitor can be calculated using the formula:
C = Q / V
Where C represents the capacitance, Q represents the charge stored in the capacitor, and V represents the voltage applied to the capacitor.
In this case, we are given that the charge stored in the capacitor is 8.89 x 10⁻⁷ C and the voltage applied is 32.0 V. Plugging these values into the formula, we get:
C = (8.89 x 10⁻⁷ C) / (32.0 V)
Simplifying the expression, we find:
C ≈ 2.78 x 10⁻⁹ F
The Farad is the SI unit of capacitance, representing the ability of a capacitor to store charge per unit voltage.

What’s this answer ?
Answer:
12
Step-by-step explanation:
The average rate of change for f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ 1, 3 ] , then
f(b) = f(3) = 27 ← value of y from table for x = 3
f(a) = f(1) = 3 ← value of y from table for x = 1
average rate of change = [tex]\frac{27-3}{3-1}[/tex] = [tex]\frac{24}{2}[/tex] = 12

Identify the solution(s) of t2+15t=−36.
Answer:
i solved for t and got
t= -3, -12
Step-by-step explanation:
Answer:
t = - 12, t = - 3
Step-by-step explanation:
Given
t² + 15t = - 36 ( add 36 to both sides )
t² + 15t + 36 = 0 ← in standard form
(t + 12)(t + 3) = 0 ← in factored form
Equate each factor to zero and solve for t
t + 12 = 0 ⇒ t = - 12
t + 3 = 0 ⇒ t = - 3

On Monday, a dental hygienist cleans teeth of 5 patients by the time she takes her lunch break at noon. On average, she is able to clean the teeth of 9 patients in 4 hours
Write a function to represent the number of patients she sees, y, and the number of hours, 2. the hygienist works after lunch on Monday.
Enter your answer in the box
PLEASE HELP!
The function that represents the number of patients she sees is; y = 9/4x + 5 and number of patients after 2 hours is 9 patients
How to write Functions?We are given;
Number of patients the dental hygeinist cleans before lunch = 5
Average number that she cleans after lunch = 9 patients in 4 hours
Thus, number of patients per hour is 9/4
The formula for slope intercept form is;
y = mx + c
Thus, equation to represent the situation in the question is;
y = 9/4x + 5
At 2 hours after lunch, number of patients is;
y = 9/4(2) + 5
y = 9.5
