James places 1 counter in the first box.he placed 2 counters in the second box,4 counters in the third box ,8 counters in the fourth box ,and continues the pattern until he gets to the tenth box how many counters did James place in the tenth box?
Answers
He placed 512 counters in the tenth box
Because... If you do a (number pattern aka a list of numbers that follow a certain sequence or pattern) your pattern will be 1,2,4,8,16,32,64,128,256,512, So in the tenth box it will be 512 because I did the pattern and reached the tenth number, which is 512 so me and Avajcantu are correct.

The probability that none of the chosen cards were spades is 27/64.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
A student draws three cards from a standard deck of cards. If the student replaces the card after each draw.
Number of spades card = 13
The number of non-spade cards would be 39
The probability that none of the chosen cards were spades = Number of favorable outcomes / total number of outcomes
= 27/64.

Two friends shop for fresh fruit. Jackson buys a watermelon for $8.85 and 3 pounds of cherries. Tim buys a pineapple for $3.35 and 2 pounds of cherries. Use the variable p to represent the price, in dollars, per pound of cherries. Write and simplify an expression to represent how much more Jackson spent.
Answers
Answer + Step-by-step explanation:
Jackson spent $8.85 on watermelon and p*3 dollars on cherries, which simplifies to 8.85 + 3p dollars.
Tim spent $3.35 on pineapple and p*2 dollars on cherries, which simplifies to 3.35 + 2p dollars.
To find how much more Jackson spent than Tim, we can subtract Tim's total cost from Jackson's total cost, giving:
(8.85 + 3p) - (3.35 + 2p) = 5.50 + p
So Jackson spent $5.50 + p more than Tim.
15 POINTSSS ANSWER ASAP PLEASE!!!!! What is the equation, in point-slope form, of the line that is
parallel to the given line and passes through the point (4, 1)?
y-1=-2(x - 4)
y-1=-{(x-4)
oy-1= (x-4)
y-1 = 2(x - 4)
Answers
Answer:
The Answer is : D
Step-by-step explanation:
First find the slope of the line that the equation should be parallel to. In this case it is 2/1 which simplified is 2.
Next insert the X (4) of the point (4,1) and solve to see if you get the Y(1).
y-1 = 2 (4-4)
y-1= 2 (0)
y-1= 0
y= 1
In this case D is correct.
TIP*
If you see the question ask you about a parallel formula, look at the slopes of them to see if they match up. Parallel formulas have the same slope, just a tip because you can see in the answer choices none of the equations have the same slope as the line on the graph except for D.

Answers
Answer: Volume of sample is 4.004 cm³
Step-by-step explanation:
Given: Density of pure silver is 10.49 g/cm³
Mass of silver = 42 grams
To find: The volume of sample
As we know
[tex]\text{ Density }= \dfrac{\text {Mass }}{\text {Volume }}[/tex]
As given in question we have
[tex]10.49 \text { g/}cm^3 = \dfrac{42 g }{\text {Volume}} \\\\\Rightarrow \text {Volume}= \dfrac{42g}{10.49\text { g/}cm^3 } \approx 4.0038 \approx 4.004 cm^3[/tex]
Hence 4. is the right option
Volume of sample is 4.004 cm³

Ok
so mean u = 79, and standard dev = s = 7
We want P(X >= 86)
Standardize:
P ( (X - u)/s >= (86 - 79)/7 ) = P (Z >= 1) = 0.1587 from the Z-scores table

Step-by-step explanation:
Given the 3 sides of a triangle, we can use Hero's formula to calculate the area (A)
A = [tex]\sqrt{s(s-a)(s-b(s-c)}[/tex]
where s s the semi perimeter and a, b , c the sides of the triangle
let a = 5, b = 9 and c = 10
s = [tex]\frac{a+b+c}{2}[/tex] = [tex]\frac{5+9+10}{2}[/tex] = [tex]\frac{24}{2}[/tex] = 12
A = [tex]\sqrt{12(12-5)(12-9)(12-10)}[/tex]

Answer:
Step-by-step explanation:
a = 5 units ; b = 9units ; c = 10 units
Semi perimeter = (a+b+c)/2 = (5+9+10)/2 = 24/2 = 12 units
s-a = 12 -5 = 7 units
s -b = 12 - 9 = 3 units
s-c = 12- 10 =2 units
[tex]Area=\sqrt{s*(s-a)(s-b)(s-c)}\\\\=\sqrt{12*7*3*2}\\\\=\sqrt{2*2*3*7*3*2}\\\\=2*3\sqrt{2*7}\\\\=6\sqrt{14}\\[/tex]

1) Flipping head, rolling a 5, and rolling a 2
2) Flipping tails, rolling an odd number, and rolling a 4
3) Flipping head, not rolling a 2, and rolling an even number
Answers
Answer:
1) 1.4%
2) 8.3%
3) 20.8%
Step-by-step explanation:
Alrighty! You are looking at some compound probability problems.
The trick with these is to figure out the probability of each piece of an event, and then multiply those together to get the overall probability.
Quick note about notation: p(event A) is short hand for saying "The probability of event A is....."
1) Flipping head, rolling a 5, and rolling a 2
P(flipping heads) = 1/2
p(rolling a 5) = 1/6
p(rolling a 2) = 1/6
so: (1/2) x (1/6) x (1/6) = 1/72 or about 1.4%
2) Flipping tails, rolling an odd number, and rolling a 4
p(flipping tails) = 1/2
p(rolling an odd number) = 3/6
p(rolling a 4) = 1/6
so: (1/2) x (3/6) x (1/6) = 3/72 or about 8.3%
3) Flipping head, not rolling a 2, and rolling an even number
p(flipping heads) = 1/2
p(not rolling a 2) = 5/6
p(rolling and even number) = 3/6
so: (1/2) x (5/6) x (3/6) = 15/72 or about 20.8%

Which matrix represents the system of equations shown below? 3x-5y=12 4x-2y=15
Answers
Answer:
[tex]\left[\begin{array}{ccc}3&-5 &|12\\4&-2 &|15\\\end{array}\right][/tex]
Step-by-step explanation:
When making a matrix of two equations with the variables x and y, the result will be a matrix with three columns:
a column for the values of x in each equationa column for the values of y in each equationa column for the independent values of each equationsince our system of equations is:
[tex]3x-5y=12\\ 4x-2y=15[/tex]
we can see that the value for x in the first equation is 3 and in the second equation is 4, thus the first column will have the numbers 3 and 4:
[tex]\left[\begin{array}{ccc}3&&\\4&&\\\end{array}\right][/tex]
Now for the values of y we hvae -5 in the first equation and -2 in the second equation, we update the matrix with another column with the values of -5 and -2:
[tex]\left[\begin{array}{ccc}3&-5&\\4&-2&\\\end{array}\right][/tex]
Finally, the last column is the independent values of each equation (or the results) in the first equation that number is 12 and in the second equation is 15, thus the matrix is:
[tex]\left[\begin{array}{ccc}3&-5&12\\4&-2&15\\\end{array}\right][/tex]
usually there is a line separating the columns for the values of x and y, and the independent values:
[tex]\left[\begin{array}{ccc}3&-5 &|12\\4&-2 &|15\\\end{array}\right][/tex]
this is the matrix of the system of equations

What number multiplied by 8 will give a product of 9.6?
Answers
Answer:
1.2
Step-by-step explanation:
Write out the equation and let mbe the missing number:
8 × m = 9.6
Divide 8 to both sides:
[tex]\frac{8}{8}[/tex] × m = [tex]\frac{9.6}{8}[/tex]
Simplify for M
m = 1.2
The number that needs to be multiplied by 8 to yield the product of 9.6 is 1.2. This is calculated by dividing 9.6 by 8.
Explanation:The student is asking to solve for a number that when multiplied by 8 results in the product of 9.6. This can be solved by a straightforward division operation. When we say, 'a number multiplied by 8 equals 9.6', we're actually writing an equation for multiplication. To get that number, we'll need to divide 9.6 by 8 because division is the inverse operation of multiplication.
Here's how you do it, step-by-step:
Write down the division operation of 9.6 ÷ 8. Perform the division.
The solution to 9.6 ÷ 8 is 1.2. So, the number multiplied by 8 to get 9.6 is 1.2.

The volume of a cylinder is 63.6 cubic inches,
and its height is 9 inches. Find the diameter of
the base of the cylinder.
Answers
Final answer:
To find the diameter of the base of the cylinder, use the formula for the volume to solve for the radius, then double the radius to find the diameter.
Explanation:
To find the diameter of the base of the cylinder, we need to first find the radius. We can use the formula for the volume of a cylinder, V = πr²h, where V is the volume, r is the radius, and h is the height. Rearranging the formula to solve for the radius, we have r = √(V/πh).
Plugging in the given values: V = 63.6 cubic inches and h = 9 inches, we can find the radius: r = √(63.6/3.142 x 9).
Calculating the values: r ≈ √(20.2649) ≈ 4.5055 inches. The diameter is twice the radius, so the diameter ≈ 2 x 4.5055 ≈ 9.011 inches.
Solve (x +9)2 = 25.
1. Apply the square root property of equality:

[tex] \sqrt{(x + 9) {}^{2} } = \sqrt{25} [/tex]
[tex]x + 9 = \: 15[/tex]
[tex]x + 9 = 5 \: or \: x + 9 = - 5[/tex]
