Answer:
It would be 30.
Step-by-step explanation:
If we make a list of all the sums that we can get, we have:
1+2, 1+3, 1+4, 1+5, 1+6, 2+3, 2+4, 2+5, 2+6, 3+4, 3+5, 3+6, 4+5, 4+6, 5+6
These 15 sums can be chosen in two ways, since order matters, and we could do 2+1 instead of 1+2.
That gets us to 15x2 which is 30.
The number of ways that we can choose the marbles such that the sum of the numbers on my marbles equals the number on his would be 30.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
I have a bag with 6 marbles numbered from 1 to 6.
Mathew has a bag with 12 marbles numbered from 1 to 12.
1+2, 1+3, 1+4, 1+5, 1+6, 2+3, 2+4, 2+5, 2+6, 3+4, 3+5, 3+6, 4+5, 4+6, 5+6
These 15 sums can be chosen in two ways,
Since order matters, and we could do 2+1 instead of 1+2.

A random number generator is used to create a list of 200 single-digit numbers. of those 200 numbers, 105 are even and ninety-five are odd. seven was generated fifteen times. what is the experimental probability of an odd number other than seven being generated? 40.0% 45.0% 47.5% 52.5%
Using it's concept, it is found that the probability of an odd number other than seven being generated is of 40.0%.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
For an experimental probability, these number of outcomes are taken from previous trials.
In this problem, 200 numbers have been generated, and 80 are odd numbers that are not seven, hence the probability is given by:

given that у=6 cm and θ=15 °, work out x rounded to 1 decimal place.
(the diagram is not drawn to scale.)
Using a trigonometric realtion, we can see that x = 23.18cm
How to find the value of x?Here we have a right triangle, we can see that y = 6cm, and the angle theta is 15°.
Notice that y is the opposite cathetus to the known angle, and we want to find the value of x, which is the hypotenuse.
Then we can use the trigonometric relation:
sin(a) = (opposite cathetus)/hypotenuse.
Reaplacing what we know, we will get:
sin(15°) = 6cm/x
Solving that for x:
x = 6cm/sin(15°9
x = 23.18cm

The attendance at a village fair depends on the weather.
The probability of a high attendance at the fair is 0.9.
This is reduced to 0.4 if it is raining.
The probability of it raining is 0.2.
What is the probability of its raining and there being a high attendance?
0.6
0.08
0.36
0.18
Answer:
B. 0.08
Step-by-step explanation:
In order to solve this problem, we must account for all possibilities. The sum of all posssiblities must sum up to 1.
1 - High Attendance/No Rain
0.9*0.8 = 0.72
2- High Attendance/ Rain
0.4*0.2 = 0.08
3 - Low Attendance/No Rain
0.1*0.8 = 0.08
4 - High Attendance/No Rain
0.6*0.2 = 0.12
Now we answer the question of rain and high attendance.
0.08/1 = 0.08

For every 36 minutes of sprinting, Scarlett earned 12 dollars for charity. To find the unit rate of this, I would first need to structure the equation. In this case, I would use division, so my equation would be 36 ÷ 12 = 3. The final answer would be, for every 3 minutes, Scarlett earns $1. is this right? i will give 15 points:)
Answer:
$1 every 3 minutes
Step-by-step explanation:
Cause every 36 minutes Scarlett earns $12 and if you divide 36 by 12 it will give 3 minutes which means she earns $1 per 3 minutes. You're right.

Find the general solution of the given differential equation. Cos(x) dy dx (sin(x))y = 1
The general solution to the differential equation is y = sinx + c cosx.
What is differential equation?It is defined as the equation which contains functions, derivative of the functions to make an expression.
We have a differential equation:
[tex]\rm cosx\left(\dfrac{dy}{dx}\right)+\left(sinx\right)y\:=\:1[/tex]
Multiply by dx:
(cosx) dy + (sinx) y dx = dx
(cosx) dy = (1 - (sinx) y) dx
After simplification and integrating, we will get:
[tex]\rm y = \dfrac{tan x}{sec x}+ \dfrac{c}{secx}[/tex]
y = sinx + c cosx
Thus, the general solution to the differential equation is y = sinx + c cosx.

30 Use the method of completing the square to determine the vertex of f(x) = x² - 14x - 15.
State the coordinates of the vertex.
Answer:
x² - 14x - 15 = (x − 7)² − 64Then the coordinates of the vertex are (7 , -64)Step-by-step explanation:
x² - 14x - 15 = x² - 14x + (49 - 49) - 15
= (x² - 14x + 49) - 49 - 15
= (x² - 14x + 7²) - 49 - 15
= (x − 7)² − (49 + 15)
= (x − 7)² − 64
x² - 14x - 15 = (x − 7)² − 64
Then the coordinates of the vertex are (7 , -64)
If x and y are complementary angles, then y is a right angle.

The equation of this sinusoidal function is either
f(x) = a sin(bx) + c
or
f(x) = a cos(bx) + c
Either way, the plot of f9x) has amplitude a, period 2π/b, and midline y = c.
If the period is π/2, then
2π/b = π/2 ⇒ b = 4
If the maximum value is 10 and the minimum value is -4, then
-4 ≤ a sin(4x) + c ≤ 10
-4 - c ≤ a sin(4x) ≤ 10 - c
-(4 + c)/a ≤ sin(4x) ≤ (10 - c)/a
Recall that sin(x) is bounded between -1 and 1. So we must have
-(4 + c)/a = -1 ⇒ a = c + 4
(10 - c)/a = 1 ⇒ a = -c + 10
Combining these equations and eliminating either variable gives
a + a = (c + 4) + (-c + 10) ⇒ 2a = 14 ⇒ a = 7
a - a = (c + 4) - (-c + 10) ⇒ 0 = 2c - 6 ⇒ c = 3
Finally, we have either
f(x) = a sin(bx) + c ⇒ f(0) = c = 3
or
f(x) = a cos(bx) + c ⇒ f(0) = a + c = 3
but the cosine case is impossible since a = 7.
So, the given function has equation
f(x) = 7 sin(4x) + 3
