Half of the time, the coin will land on heads and the cube will land on an even number when Patty tosses the coin and rolls the number cube 60 times.
What is binomial probabilities?The binomial probabilities is the experimental probability in which the total number of output values is 2, therefore it is known as binomial probabilities.
The number of independence variable in case of binomial experiments is fixed. Both the two output has the 1/2 chances to occur.
Patty tosses the coin and rolls the number cube 60 times.
For the coin, there are total 120 outcomes for 60 tosses, in which 60 favorable outcomes to land on heads. Thus, the probability the coin will land on heads is,
[tex]P=\dfrac{60}{120}\\P=\dfrac{1}{2}[/tex]
For the number cube, there are total 360 outcomes (6×60) for 60 rolls, in which 180 favorable outcomes (3×60) to land on even number. Thus, the probability the number cube will land on even number is,
[tex]P=\dfrac{180}{360}\\P=\dfrac{1}{2}[/tex]
Hence, half of the time, the coin will land on heads and the cube will land on an even number when Patty tosses the coin and rolls the number cube 60 times.

Find the value of x that makes m congruent to n
Answer:
x=10
Step-by-step explanation:
13x=130
because they are parallel we know that line m and n are equal angles
since 13x° and 130° aee both obtuse angles they are equal
so set them equal 13x=130
and solve for x
divide both sides by 13
(13x)/13 = 130/13

The graph of the function y = 2x^2 + bx + 8 is shown.
What is the value of b?
The value of b is 4 and the function becomes y = 2x²-12x+8 because (2, -8) lie on the function.
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
We have:
[tex]\rm y = 2x^2+bx+8[/tex]
The above function shows the equation of the parabola.
From the graph, we can see the point(2, -8) lie on the graph of the function,
So point(2, -8) will satisfy the function.
Plug y = -8 and x = 2 in the function.
[tex]\rm -8 = 2(2)^2+b(2)+8\\\\-16 = 8+2b\\-24 = 2b \\b = -12[/tex]
Thus, the value of b is 4 and the function becomes y = 2x²-12x+8 because (2, -8) lie on the function.

The sum of two complex numbers is −3 + 5i. If one of the complex numbers is 1−8i, which answer choice below is the other number?
Answer:
C
Solution
For a complex number written in the form a + bi, a is called the real part of the complex number and b is called the imaginary part. The sum of two complex numbers, a + bi and c + di, is found by adding real parts and imaginary parts, respectively, that is, (a + bi) + (c + di) = (a + c) + (b + d)i. Therefore, the sum of 2 + 3i and 4 + 8i is (2 + 4) + (3 + 8)i = 6 + 11i.
Choice A is incorrect and is the result of disregarding i and adding all parts of the two complex numbers together, 2 + 3 + 4 + 8 = 17. Choice B is incorrect and is the result of adding all parts of the two complex numbers together and multiplying the sum by i. Choice D is incorrect and is the result of multiplying the real parts and imaginary parts of the two complex numbers, (2)(4) = 8 and (3)(8) = 24, instead of adding those parts together.

D. f(x) = 1/16(x + 9)^2 - 19 =
Answer:
b
Step-by-step explanation:
on plato
The equation of the parabola opening upward with a focus at and a directrix will be f(x) = 1/32(x + 9)^2 + 19. so option B is correct.
What is the equation of the parabola?The equation can be written as
f(x) = 1/(4p)(x -h)^2 +(k-p)
where (h, k) is the focus, and p is half the distance between focus and directrix.
Here, We have the upward parabola;
(h, k) = (-9, 7) and p = (7 - (-9))/ 2 = 8.
So the equation is
f(x) = 1/32(x + 9)^2 + 19
The equation of the parabola opening upward with a focus at and a directrix will be f(x) = 1/32(x + 9)^2 + 19. so option B is correct.

The residual value is the difference in the value of the y coordinate between the real value and the expected value. The residual value will be equal to -0.86.
What is residual value?The residual value is the difference in the value of y coordinate between the real value and the expected value.
Residual Value = Real value of y - The predicted value of y
The value of y in the table is -2 when the value of x is 5. And as per the function, the value of y when the value of x is 5 can be written as,
[tex]y = -0.7x+2.36\\\\y = -0.7(5)+2.36\\\\y= -3.5+2.36\\\\y=-1.14[/tex]
Now, the residual value can be written as,
[tex]\text{Residual Value} = \text{(Value of y in the table)} - \text{(Value of y as per the function)}\\\\\text{Residual value} = -2 - (-1.14)\\\\\text{Residual value} = -2+1.14\\\\\text{Residual value} = -0.86[/tex]

The height of an object after it is released can be modeled by the function f (x) = negative 16 t squared v t s, where t is the number of seconds after the object is released, v is the upward speed in feet per second at release, and s is the starting height in feet. if a quarterback throws a ball from his hand 6 feet in the air at an upward speed of 25 feet per second, how much time does his teammate have to catch the ball?
The amount of time his teammate have to catch the ball is equal to 1.774 seconds.
Given the following function:
f(x) = -16t² + vt + s.Displacement, s = 6ft.Velocity, v = 25 ft/s.How to calculate the amount of time?In order to determine the amount of time his teammate have to catch the ball, we would evaluate the given position-time function as follows:
f(t) = -16t² + 25t + 6.
In Mathematics, the standard form of a quadratic equation is given by;
ax² + bx + c =0
Where:
a = -16.
b = 25.
c = 6.
Solving the function by using the quadratic formula, we have:
t = [-b ± √(b² - 4ac)]/2a
t = [-25 ± √[(25² - 4(-16)(6))]/2(-16)
t = [25/32 ± (-1/32)√1009]
t = 25/32 ± (-0.993)
t = 0.781 ± 0.993
t = 0.781 + 0.993
Time, t = 1.774 seconds.

PLEASE HELP If a fair coin is tossed 9 times, what is the probability, to the nearest thousandth, of getting exactly 1 heads?
The probability of getting exactly 1 head when a fair coin is tossed 9 times is approximately 0.017, to the nearest thousandth.
To find the probability of getting exactly 1 head when a fair coin is tossed 9 times, we can use the concept of binomial probability. The probability of getting a head on a single coin toss is 1/2, and the probability of getting a tail is also 1/2.
In this case, we want to calculate the probability of getting exactly 1 head out of 9 tosses. This can be represented as a binomial probability with parameters n (number of trials) and p (probability of success).
Using the binomial probability formula:
P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)
where n is the number of trials, k is the number of successful outcomes, and p is the probability of success.
In our case, n = 9, k = 1, and p = 1/2.
Plugging these values into the formula:
P(X = 1) = (9 choose 1) * (1/2)^1 * (1 - 1/2)^(9 - 1)
P(X = 1) = 9 * (1/2) * (1/2)^8
P(X = 1) = 9 * (1/2)^9
P(X = 1) = 9/2^9
P(X = 1) ≈ 0.017
Therefore, the probability of getting exactly 1 head when a fair coin is tossed 9 times is approximately 0.017, to the nearest thousandth.

The ratio of girls to boys in the school marching band is 3 to 2. If there are 24 boys in the marching, how many of the students in the marching band are girls.
A.42
B.28
C.32
D.36
Answer:
D. 36
Step-by-step explanation:
Ratios are a way to represent of how much there is one thing to another. It's a more simplistic representation.
For example, if there were 625 adults and 375 children, we don't say there are 625 adults to 375 children, we say there are 5 adults to 3 children.
All I did was divide both the number of children and adults by 125 and we have a ratio of 5:3 for adults to children respectively.
In this problem, we have a ratio of 3:2 for girls to boys. This 3:2 ratio is a simplistic representation of the number of girls to boys. We know that there are 24 boys.
Dividing 24/2 = 12
12 is the proportion which we multiply by the ratio to get the true numbers for boys and girls.
2 * 12 = 24 boys
3 * 12 = 36 girls
So there are 36 girls in the marching band.
I know this is super random but I was never shown in class how to actually do this type of problem so if you could give an explanation it would be so so helpful :)

$140 was the original price.
discount : 45%
45% ⇒ $63
1% ⇒ $(63/45)
1% ⇒ $1.4
original price is always 100%
100% ⇒ $(1.4*100)
100% ⇒ $140
Let the original price of the necklace be ,'x',

According to the question,
