A box contains 16 chocolates, of which
3 are known to contain nuts.
Two chocolates are selected at random.
a. Find the probability that
a exactly one chocolate contains
nuts
b at least one chocolate contains
nuts.
Answer:
3/16??? and 1/16???
Step-by-step explanation:
im so sorry this might be wrong
The probability that a exactly one chocolate contains nuts is 3/16 and probability that at least one chocolate contains nuts is 0.339.
How to calculate probability ?Probability is calculated by dividing the number of possible outcomes by the total number of possible outcomes. Probability and odds are two distinct concepts. Odds are calculated by dividing the probability of something happening by the probability of it not happening.
When you calculate probability, you are estimating the likelihood of something occurring and representing it with a precise number.
The probability that a exactly one chocolate contains nuts
No of total chocolates = 16 chocolates
No of chocolates contain nuts = 3
The probability that a exactly one chocolate contains nuts = 3/16
Probability that at least one chocolate contains nuts is
P(at least one contains nut) = 1 – P(given contains no nuts )^n
P(at least one contains nut) = 1 – (0.8125)^2
P(at least one contains nut) = 0.339
Probability that at least one chocolate contains nuts = 0.339

what is the symbolic representation for this argument
iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
suppose f(×) = 2^×, sketch a graph of f(×) and f^-1(×)
Let f(x) = y
y = 2^x
x = 2^y
Solve for y.
ln x = ln(2^y)
ln x = y ln 2
ln x/ln 2 = y
Replace y with f^(-1) x.
f^(-1) x = ln x/ln 2
We now know f(x) and f^(-1) x.
Use your graphing calculator to graph the function and its inverse on the same xy-plane. If you don't have a graphing calculator, use DESMOS online.

Answer:
50m²
Explanation:
first, we have to find the length and width of the backyard. since 4cm represents 5m, we know that the real width of the backyard is 5m.
as for the length of the backyard, 8cm is double of 4cm so we can also double 5m to get 10m.
now, we can find the area by taking 5m × 10m = 50m².

Instructions require you to dilute a powder in 3 quarts of water. You only have a container that is marked in liters. How many liters would you use to dilute the powder?
Answer:
1 quart = .947 L
3 Q = 2.841 L
So you should use 2.841 L to dissolve the powder
One quartz is equal to 32 oz, then 2.88 liters of water are used to dilute the powder.
What is a conversion of units?The unit conversion deals with the operation to change one form of the unit to another form of unit.
Instructions require you to dilute a powder in 3 quarts of water. You only have a container that is marked in liters.
We know that
1 quartz = 32 oz
3 quartz = 96 oz
Since 30 milliliters per oz
Then
30 milliliters × 96 oz = 2880 milliliters
Since 1000 milliliters per liter, then we have
[tex]\rm \dfrac{2880}{1000}=2.88\ liters[/tex]
2.88 liters are used to dilute the powder.

The number of light bulbs produced by a company can be modeled by the expression
15x^3+16x^2–100x+51, where x is the number of years passed since 1980. The number of companies
purchasing the light bulbs is represented by 5x–3. Which is the expression representing the average number
of light bulbs purchased per company?
Answer:
Expression is 3x² + 5x - 17
Step-by-step explanation:
We are told the number of lights produced by a company is;
Number of lights = 15x^3 + 16x^2 – 100x + 51
Also, number of companies that purchased the light bulbs is 5x - 3.
Thus;
The average number of bulbs purchased per company = (15x^3 + 16x^2 – 100x + 51)/(5x - 3)
I have attached the calculation using long division method to get;
3x² + 5x - 17

if each quadrilateral below is a square, find the missing measures.
please help :(
We want to find the missing measures for the given square.
VU = 15TV = 21.2SU = 21.2SW = 10.6Working with squares.
We know that squares have the same length in all of their 4 sides, with that in mind we can see that:
TS = TU = UV = SV = 15
Then we can already complete:
VU = 15
Now we need the two diagonals, SU and TV.
The diagonal for a square of side length s is:
diagonal = (√2)s
Then the diagonals for our square are:
TV = SU = (√2)*15 = 21.2
And SW is half of the diagonal, so we have:
SW = 21.2/2 = 10.6

900 students attend Ridge wood Junior High School. 25% of students bring their lunch to school everyday. How many students brought their lunch to school on Thursday
Answer:
225 students
Step-by-step explanation:
Total number of students = 900 students
percent that bring lunch to school everyday = 25%
Number of student that bring lunch to school = 25% of 900
Number of student that bring lunch to school = 0.25 * 900
Number of student that bring lunch to school = 225
Hence 225 students bring lunch to school everyday

Answer:
x = 12
m(QS) = 52°
m(PD) = 152°
Step-by-step explanation:
Recall: Angle formed by two secants outside a circle = ½(the difference of the intercepted arcs)
Thus:
m<R = ½[m(PD) - m(QS)]
50° = ½[(12x + 8) - (4x + 4)] => substitution
Solve for x
Multiply both sides by 2
2*50 = (12x + 8) - (4x + 4)
100 = (12x + 8) - (4x + 4)
100 = 12x + 8 - 4x - 4 (distributive property)
Add like terms
100 = 8x + 4
100 - 4 = 8x
96 = 8x
96/8 = x
12 = x
x = 12
✔️m(QS) = 4x + 4 = 4(12) + 4 = 52°
✔️m(PD) = 12x + 8 = 12(12) + 8 = 152°

Solve the Linear-Quadratic System of Inequalities. Shade the solution on the graph provided.
y > x^2 - 1
-1/2x + 3 < y
Answer:
We have the system:
y > x^2 - 1
y < (-1/2)*x + 3
To find the solutions of this set we need to graph the solutions range of both sets, and see the intersection between these solution ranges.
How we do it?
Start with the first one.
First, we graph the equation:
y = x^2 - 1
Now because we are using the symbol ">" means that y is smaller than the thing at the right, then the graph of the equation will be with a dashed line (which means that the points on the line are not solutions) and we will shade all the region above the line
For the other inequality we do the same:
First we graph:
y = (-1/2)*x + 3
And because we have the symbol "<" we again use a dashed line, but this time we will shade all the region below the line.
Once we shaded both regions, the region where we have both shades will be the region of solutions for the system of inequalities.
You can see the graph below.

Step-by-step explanation:
Find the original total stories 10 + 8 + 16 + 8 = 42.
Original ratio of Mary's stories to total stories is 8/42 or 4/21.
Then form equation 4/21 = 12/x ; multiply both sides of 4/21 by 3.
4/21 = 12/63
The students need to write 63 stories to keep the ratio of Mary's stories to total stories the same.
Without graphing the equations, decide whether the system has one solution, no solution, or infinitely many solutions.
2y = x - 7
5x - 4y = 14
How many solutions does the system have?
A. Infinitely many solutions
B. One solution
C. No solution
