A bag contains two coins, one for which the probability of heads is equal to 1 and one for which the probability of heads is equal to p. A coin is selected at random, and three independent tosses of this coin result in three heads. What is the probability that a further independent toss of this coin will produce a head?a. p4/1 + p3.b. p3 - p2/1 + p3.c. p3/1 - p.d. 1/1 + p3.e. 1 + p4/1 + p3.
Answer: Option E is the correct answer; (1 + p⁴) / (1 + p³)
Step-by-step explanation:
P (3 head) = P(first and 3 heads) + P(second coin and 3 heads)
= (1/2)×1³ + (1/2)× p³ = (1/2) × (1 + p³)
therefore P(first coin given 3 heads) = (1/2)×1³/ ((1/2)×(1 + p³))
= 1 / (1 + p³)
Also P( second coin given 3 heads) = p³ /(1 + p³)
therefore P(4th toss in heads given first 3 are heads) will be;
= P(first and 4th toss heads) + P(second and 4th toss heads)
=(1/( 1 + p³ )) × 1 + p³ / (1+p³) × p
= (1 + p⁴) / (1 + p³)
Therefore Option E is the correct answer

The range of a set of scores is 27, and the lowest score is 39. Write and
solve an equation to find the highest score. (Hint: In data sets, the range is
the difference between the highest and the lowest values.) *
Answer: The highest score is 66
Step-by-step explanation: First we need to set the problem up.
x - 39 = 27
Next solve the problem.
Get x by itself by getting rid of the negative 39
x - 39 + 39 = 27 + 39
Add/Subtract
x = 66
You don’t need to simplify anymore so leave the problem alone since you already have the answer.

Element X decays radioactively with a half life of 9 minutes. If there are 610grams of
Element X, how long, to the nearest tenth of a minute, would it take the element to
decay to 124 grams?
y = a(.5) t/h
A half-life of 9 minutes corresponds to a decay factor k such that
[tex]\dfrac12=e^{9k}\implies k=-\dfrac19\ln\left(\dfrac12\right)[/tex]
Then the time it takes for the substance to decay from 610 g to 124 g is time t such that
[tex]124\,\mathrm g=(610\,\mathrm g)e^{kt}[/tex]
Solve for t :
[tex]\dfrac{62}{305}=e^{kt}[/tex]
[tex]\ln\left(\dfrac{62}{305}\right)=kt[/tex]
[tex]t=\dfrac1k\ln\left(\dfrac{62}{305}\right)\approx20.686[/tex]
so it takes about 20.7 min for the 610 g sample to decay down to 124 g.

which expression is equivalent to 40x^2 square root x^12 ÷ 10^2 square root 29x^8, if x does not equal 0?
The expression that is equivalent to the given expression is 10(2x)².
Equivalent expressionThe equivalent expression is obtained by simplifying the given expression as shown below;
40x², where, x ≠ 0
expand the expression as follows;
40x² = (10 x 4)x²
= (10 x 2²)x²
= 10(2²x²)
= 10(2x)²
Thus, the expression that is equivalent to the given expression is 10(2x)².

Solve the system by substitution.
y = -5x + 40
y = 3x
Answer:
X=5 y=15
Step-by-step explanation:
you got to solve the first variable in the first equation, then substitute the result in to the other.
Solution for the system of equations y = -5x + 40 and y = 3x are:
x = 5 , y = 15 .
What is substitution method?The substitution method is the algebraic method to solve simultaneous linear equations. As the word says, in this method, the value of one variable from one equation is substituted in the other equation.
Given equations
y = -5x + 40 ------(a)
y = 3x -------(b)
Substituting value of y from equation (b) to equation(a)
3x = -5x + 40
⇒ 3x + 5x = 40
⇒ 8x = 40
⇒ x = 40/8
⇒ x = 5
Substituting value of x in equation (b)
y = 3 × 5
⇒ y = 15
Hence, x = 5 and y = 15 are the solutions
for the system of equations
y = -5x + 40 and y = 3x

A(5, 8) and B(-1,-4)
Find the coordinates of the midpoint
Answer:
[tex]m = (2,6)[/tex]
Step-by-step explanation:
Given
A(5, 8) and B(-1,-4)
Required
Determine the midpoint
Represent the midpoint with m
m is calculated as thus:
[tex]m = (\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})[/tex]
Where:
[tex](x_1,y_1) = (5,8)[/tex] ---- A
[tex](x_2,y_2) = (-1,4)[/tex] ------ B
So, the expression:
[tex]m = (\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})[/tex]
becomes
[tex]m = (\frac{5 -1}{2},\frac{8 + 4}{2})[/tex]
[tex]m = (\frac{4}{2},\frac{12}{2})[/tex]
[tex]m = (2,6)[/tex]
Hence, the coordinates of the midpoint is: (2,6)

b) 15 cm + 5 cm + 7 cm
c) 15 cm x 5 cm + 7 cm
d) 15 cm + 5 cm x 7 cm
Responder:
a) 15 cm x 5 cm x 7 cm Explicación paso a paso:
Nota: no se adjuntó ninguna imagen a esta pregunta, sin embargo, podemos proceder a una solución a este problema.
Paso uno: Datos dados Podemos deducir de las opciones que los parámetros de la caja son los siguientes
Largo L = 15cm
Ancho W = 5cm
Altura H = 7 cm
Segundo paso: El espacio que ocupa la caja en el armario es equivalente al volumen de la caja. Por tanto, el volumen de la caja se expresa como
Volumen = L * W * H
Volumen = 15 cm * 5 cm * 7 cm
Por tanto, la opción A es correcta
Sandy has around $245 in her pocket but she thinks she could have up to $25 more or $25 less. Write and solve an absolute value equation that can show the maximum and minimum amount of money that Sandy has in her pocket.
Answer:
The absolute value equation is |x - 245| = 25The maximum amount of money in Sandy's pocket is $270The minimum amount of money in Sandy's pocket is $215Step-by-step explanation:
The absolute value equation for the amount of money in Sandy's pocket is given as;
|x - 245| = 25
The equation for the maximum amount of money in Sandy's pocket is given as;
x - 245 = 25
x = 25 + 245
x = $270
The equation for the minimum amount of money in Sandy's pocket is given as;
x - 245 = -25
x = -25 + 245
x = $215

What is a pentahedron?A Square Pyramid is a pyramid with the base as a square. It is also known as pentahedron. It has 5 faces out of which 4 are triangles while 1 is a square.
The volume of the square pyramid is one-third of the product of the area of the square and the height of the pyramid. Thus, the volume of the square pyramid with a side length of 142 m and a height of 93 m can be written as,
[tex]\rm \text{Volume of square pyramid} = \dfrac13 \times \text{(Area of square)} \times Height[/tex]
[tex]= \dfrac13 \times (142)^2 \times 93\\\\= 625,084\rm\ m^3[/tex]
Hence, the volume of the ancient stone pyramids in Egypt with a side of 142 m and a height of 93 m is 652,084 m³.
