There are 30 chocolates in a box, all identically shaped. There are 11 filled with nuts, 10 with caramel and 9 are solid chocolate. You randomly select one piece, eat it and then select a second piece. What is the probability of selecting two solid chocolates in a row?
Answer:
I think the answer is 4 1/2 out of 30 chance.
Step-by-step explanation:
The probability of selecting two solid chocolates in a row is 4/145.
Explanation:To calculate the probability of selecting two solid chocolates in a row, we need to consider the probability of selecting a solid chocolate on the first draw and the probability of selecting a solid chocolate on the second draw, given that a solid chocolate was selected on the first draw.
There are a total of 30 chocolates, with 9 solid chocolates. Therefore, the probability of selecting a solid chocolate on the first draw is 9/30.
After eating the first chocolate, there are now 29 chocolates left in the box, with 8 solid chocolates remaining. So the probability of selecting a second solid chocolate is 8/29.
Since the two events are independent, we can multiply the probabilities of each event to find the probability of both events occurring:
Probability of selecting two solid chocolates = (9/30) * (8/29) = 4/145.

Answer:
1229 km
Step-by-step explanation:
The missing angle is ...
180° -60° -75° = 45°
Knowing that, the Law of Sines can be used to find the side opposite the 75° angle.
?/sin(75°) = 900 km/sin(45°)
? = (900 km)sin(75°)/sin(45°) ≈ 1229.423 km
The UFO is about 1229 km from KA-12.
Trinity takes a sample of 50 songs and finds that 20 are by a female artist. Based on this problem, which of the following is a 99% confidence interval for the proportion of songs on her phone by a female artist?
Answer: (0.2215, 0.5785)
Step-by-step explanation:
Given, Trinity takes a sample of 50 songs and finds that 20 are by a female artist.
Let p be the proportion of songs on her phone by a female artist.
Then , the 99% confidence interval for p would be :-
[tex]\hat{p}\pm z\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex] ...(i)
As per given , Sample size : n= 50
Sample proportion of songs on her phone by a female artist. [tex]\hat{p}=\dfrac{20}{50}=0.4[/tex]
For 99% confidence level , critical z-value =2.576
Substituting values in (i), we get
[tex]0.4\pm 2.576(\sqrt{\dfrac{0.4(1-0.4)}{50}})\\\\=0.4\pm 2.576\sqrt{0.0048}\\\\\approx0.4\pm0.1785\\\\=(0.4-0.1785,\ 0.4+0.1785)\\\\=(0.2215,\ 0.5785)[/tex]
Hence, a 99% confidence interval for the proportion of songs on her phone by a female artist : (0.2215, 0.5785)
What is the value of x?
Answer:
x = 6
Step-by-step explanation:
8^2 + x^2 = 10^2
64 + x^2 = 100
x^2 = 36
x = 6 (-6 can't be a length)
Answer:
The Answer Is 6
Step-by-step explanation:
By Pythagoras Theorem
(AC)^2 = (AB)^2 + (BC)^2
(AB)^2 = (AC)^2 - (BC)^2
(AB)^2 = (10)^2 - (8)^2
(AB)^2 = 100 - 64
(AB)^2 = 36
(AB) = 6
AB = X = 6
identify the solution to the system of equations
Answer:
(-2, -1).

When trying to find the solution to a system of equations graphically, all you need to do is find the point of intersection between the two equations.
In the graph pictured, we can see that the two equations intersect at (-2,-1).
Write an inequality, in slope-intercept form, for the graph below. If necessary,
use "=" for < or ">=' . will give brainliest for the correct answer
Answer:
[tex]\displaystyle y > \frac{1}{4} x+1[/tex]
Step-by-step explanation:
To find the inequality of the shaded area which passes through points (-4, 0) and (4, 2), first we need to find the equation of the line.
To find the equation that passes through (x₁, y₁) and (x₂, y₂), we use this formula:
[tex]\boxed{\frac{y-y_1}{y_2-y_1}=\frac{x-x_1}{x_2-x_1} }[/tex]
Given:
[tex](x_1,y_1)=(-4,0)[/tex][tex](x_2,y_2)=(4,2)[/tex]Then:
[tex]\begin{aligned}\frac{y-y_1}{y_2-y_1}&=\frac{x-x_1}{x_2-x_1}\\\\\frac{y-0}{2-0}&=\frac{x-(-4)}{4-(-4)}\\\\\frac{y}{2}&=\frac{x+4}{8}\\\\y&=\frac{1}{4}x+1 \end{aligned}[/tex]
Now, we look at the line in the graph. Since the line is a dotted line, which means that the line is excluded from the shaded area. Then we can only use < or > for the inequality (instead of ≤ or ≥).
Finally, we look at the shaded area. Since the area is above the line, which means the y-value of the area is larger than the y-value of the equation (line), then we will use the larger than sign (>) and the answer will be:
[tex]\displaystyle y > \frac{1}{4} x+1[/tex]
a) 7.7 ft
b) 13.4 ft
c) 10.3 ft
d) 12.3 ft
Answer:
D. 12.3 ft
Step-by-step explanation:
This problem requires the use of trigonometric ratios. This one specifically uses the cosine ratio as it provides the hypotenuse and is asking for the side that is adjacent to the angle.
cos(40°)=a/16
cos(40°)×16=a/16×16
cos(40°)×16=a
a=12.256 ft
The length of side a is D. 12.3 ft.

How do I solve for e?
9e+4=-5e+14+13e
Answer: e = 10
Step-by-step explanation: 9e + 4 = -5e + 14 + 13 e
Now lets bring the variables and numbers on a different side
Remember that when the numbers go to the other side the sign changes
so 4 - 14 = -9e + 13e -5e
-10 = -e
10 = e
if plug in both equations on a graph then you will see that when e = 10 the lines meet at 94.
Answer:
[tex]e=10[/tex]
Step-by-step explanation:
[tex]9e+4=-5e+14+13e[/tex]
Simplify both sides by combining [tex]-5e+13e[/tex] :
[tex]9e+4=8e+14[/tex]
Isolate the variable e. Subtract 8e from both sides:
[tex]9e-8e+4=8e-8e+14\\\\e+4=14[/tex]
Subtract 4 from both sides:
[tex]e+4-4=14-4\\\\e=10[/tex]

If you flip a coin and roll a 666-sided die, what is the probability that you will flip a heads and roll a 555?
Answer:
Assuming that the die has sides that are equal and that the sides are numbered 1 to 666 (since there are 666 sides), then the probability of rolling a 555 and flip a heads is 1/1,332.
Step-by-step explanation:
Probability of flipping a heads: 1/2
Probability of rolling a 555: 1/666
Multiply the two probabilities to get your probability for rolling both.
1/2 times 1/665 is 1/1,332.

O 10 units
complete question:
The volume of the sphere is 500/3 π cubic units. What is the value of x?
x = radius
Answer:
x = 5 units
Step-by-step explanation:
The volume for a sphere can be represented as follows
volume = 4/3πr³
volume = 500/3 π
x = radius
volume = 4/3πx³
500/3 π = 4/3 × π × x³
multiply both sides by 3/4
500/3 × π × 3/4 = π × x³
125π = πx³
divide both sides by π
x³ = 125π/π
x³ = 125
cube root both sides
x³ = ∛125
x = 5 units

6/3=2 peanut butter cups
3/3=1 chocolate
then add them together to get 6
Answer: 6 pieces of candy
Step-by-step explanation:
Assuming lollipops, peanut butter cups, and chocolate are wanted in 3 bags, we would add all the candy together.
9+6+3=18
We have a total of 18 candies. Since we have to split the candy into 3 bags, you would divide 18 by 3.
18/3=6
There will be 6 pieces of candy in each bag.

They're same side interior angles because since it's a parallelogram, the lines are parallel, and in this case, AB and CD are the parallel lines, AD is the transversal, and therefore, x and 115 are same side interior.
Same side interior angles are supplementary so x + 115 = 180
x = 180 - 115 = 65

Answer:
A line passing through (1, 3) and (5, 11)
Rate of change = 2
Step-by-step explanation:
Rate of change = change in y / change in xr = Δy/ΔxLet's get the rate of change for each line:
A line passing through (-1, 4) and (1, 7).
r = (7 - 4) / (1 -(-1)) = 3/2A line passing through (1, 3) and (5, 11).
r = (11 - 3) / (5 - 1) = 8/4 = 2A line passing through (1, 1) and (4, -3).
r = (- 3 - 1) / (4 - 1) = -4/3A line passing through (0, 6) and (12, 9)
r = (9 - 6) / (12 - 0) = 3/12 = 1/4Comparing the values of r, we can see the greatest one is 2 for the line passing through (1, 3) and (5, 11)

Answer:
y = sin(x+90)
Step-by-step explanation:
The shape of the graph shown is a y = cos x graph
Since that is not an option, we know that it must be translated somewhat
Sin x and cos x graphs are the exact same in shape, but differ by 90°
Y = sin (x+90) is the same as a Y = cos x graph, so Y = sin(x+90) is our answer

A parallelogram has an area of x2+ 9x− 36.
a.What are expressions for the length and width of the parallelogram?
b.If x is an integer, what is the least possible value of x for a parallelogram to exist? Explain.
Answer:
a) Length [tex]x + 12[/tex], Width [tex]x - 3[/tex], b) [tex]x = 3[/tex]
Step-by-step explanation:
a) The expressions for the length and width of the parallelogram can be determined by factorizing the polynomial:
[tex]A = x^{2} + 9\cdot x - 36[/tex]
[tex]A = (x+12)\cdot (x-3)[/tex]
Length
[tex]x + 12[/tex]
Width
[tex]x - 3[/tex]
b) Since area is a positive variable, the set of solutions encompass all values of x such that area is zero o greater. Then, there are two interval where A is positive:
- When both binomials are negative.
[tex]x \leq 3[/tex] and [tex]x \leq -12[/tex]
[tex]x \leq -12[/tex]
- When both binomials are positive.
[tex]x \geq 3[/tex] and [tex]x \geq -12[/tex]
[tex]x \geq 3[/tex]
Since x is an integer, x must be positive and therefore the least possible value of x is:
[tex]x = 3[/tex]
