Answer:

Step-by-step explanation:
P, that each bulldozer will be operational for atleast 6 months = 0.6
p = 0.6 ; q = 1 - p = 1 - 0.6 = 0.4
Number of bulldozers purchased, n = 4
Probability that :
Exactly 0 bulldozer will be operational at the end of 6 months :
P(x = x) = nCx * p^x * q^(n-x)
P(x = 0) = 4C0 * 0.6^0 * 0.4^4
P(x = 0) = 1 * 1 * 0.0256
P(x = 0) = 0.0256
Probability that :
Exactly 1 bulldozer will be operational at the end of 6 months :
P(x = x) = nCx * p^x * q^(n-x)
P(x = 1) = 4C1 * 0.6^1 * 0.4^3
P(x = 1) = 4 * 0.6 * 0.064
P(x = 1) = 0.1536
Probability that :
Exactly 2 bulldozer will be operational at the end of 6 months :
P(x = x) = nCx * p^x * q^(n-x)
P(x = 2) = 4C2 * 0.6^2 * 0.4^2
P(x = 2) = 6 * 0.36 * 0.16
P(x = 2) = 0.3456
Probability that :
Exactly 3 bulldozer will be operational at the end of 6 months :
P(x = x) = nCx * p^x * q^(n-x)
P(x = 3) = 4C3 * 0.6^3 * 0.4^1
P(x = 3) = 4 * 0.216 * 0.4
P(x = 3) = 0.3456
Probability that :
Exactly 4 bulldozer will be operational at the end of 6 months :
P(x = x) = nCx * p^x * q^(n-x)
P(x = 4) = 4C4 * 0.6^4 * 0.4^0
P(x = 1) = 1 * 0.1296 * 1
P(x = 1) = 0.1296

Autumn wants to calculate the area of the regular hexagon below using rectangles and triangles. What is the minimum number of shapes she could use?
Two triangles and one rectangle
Two rectangles and one triangle
Two triangles and two rectangles
no rectangles and 6 triangles
Answer:
A. Two triangles and one rectangle.
Step-by-step explanation:
A regular hexagon has all six sides to be equal in length. The sum of its interior angle can be determined by:
sum of angles = (n - 2) x 180
So that some series of different shapes can be produced from the polygon. In the given hexagon, the minimum number of shapes that can be produce is 3 which are; 2 triangles and a rectangle.

Solve for.x.
10x-7
3x-4
Answer:
Length of side having 3x-4 is half of length having 10x-72 by property of triangle.
So
2*(3x-4) = 10x - 72
6x - 8 = 10x - 72
10x - 6x = 72 - 8
4x = 64
X = 64/4
x = 16

Imagine that Dr. Jones publishes a study that claims that drinking while pregnant is dangerous for the health of the unborn baby. He surveys 200 women and finds that of the 100 women in his study who drank when pregnant, 78 had children who experienced problems with attention. Of the 100 women in his study who did not drink when pregnant, only 29 children experienced problems with attention. Your neighbor says that Dr. Jones is wrong because she drank when pregnant and her child is perfectly healthy. Explain why Dr. Jones is NOT wrong.
Answer:
Kindly check explanation
Step-by-step explanation:
Dr. Jones conclusion was based on probability which measures the degree of likelihood of an occurrence or event. In his experiment, the result could be interpreted using point estimate to mean that ; 78/100 = 0.78 or 78% of those who drank while pregnant has problem with attention while only 29/100 = 0.29 or 29% of those who did not drink.
This conclusion means that pregnant women who drink have a higher likelihood of giving birth to a child with attention problem than pregnant women who do not drink. Hence, the fact that someone who drank gave birth to a perfectly healthy child does not discredit or annull Dr. Jones study.

Step-by-step explanation:
The solution to the equation is y=14/15.
The given equation is -3y+2/3=2y-4.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Now, transpose -3y to RHS and simplify.
That is, 2/3=5y-4
Transpose -4 to LHS and simplify.
That is, 14/3=5y
Multiply by 1/5 on both sides of the equation.
So, 14/3×1/5=5y×1/5
⇒y=14/15
Therefore, the solution to the equation is y=14/15.

Sea un cuadrado de 2 pulgadas de lado uniendo los puntos medios se obtiene otro cuadrado inscrito en el anterior si repetimos este proceso obtenemos una progresión de infinitos cuadrado comprobar que la área de los infinitos cuadrados forman una progresión geométrica y calcula la suma de todas las áreas
Answer:
1) La serie geométrica formada es
4, 2, 1,..., ∞
2) La suma al infinito de las áreas de los cuadrados es 8 in.²
Step-by-step explanation:
1) El área del primer cuadrado, a₁ = 2² = 4 pulgadas²
El área del siguiente cuadrado, a₂ = (√ (1² + 1²)) ² = (√2) ² = 2 pulg²
El área del siguiente cuadrado, a₃ = ((√ (2) / 2) ² + (√ (2) / 2) ²) = 1 pulg²
Por lo tanto, la razón común, r = a₂ / a₁ = 2/4 = a₃ / a₂ = 1/2
Las áreas de los cuadrados progresivos forman una progresión geométrica como sigue;
4, 4×(1/2), 4 ×(1/2)²,...,4×[tex](1/2)^{\infty}[/tex]
De donde obtenemos la serie geométrica formada de la siguiente manera;
4, 2, 1,..., ∞
2) La suma de 'n' términos de una progresión geométrica hasta el infinito para -1 <r <1 se da como sigue;
[tex]S_{\infty} = \dfrac{a}{1 - r}[/tex]
Por lo tanto, la suma de las áreas de los cuadrados hasta el infinito se obtiene sustituyendo los valores de 'a' y 'r' en la ecuación anterior de la siguiente manera;
[tex]La \ suma \ al \ infinito \ del \ cuadrado \ S_{\infty} = \dfrac{4 \ in.^2}{1 - \dfrac{1}{2} } = \dfrac{4 \ in.^2}{\left(\dfrac{1}{2} \right)} = 2 \times 4 \ in.^2= 8 \ in.^2[/tex]
La suma al infinito de las áreas de los cuadrados, [tex]S_{\infty}[/tex] = 8 in.²

A square garden has a diagonal of 12m. What is the perimeter of the garden? Express in simplest radical form.
Answer:
24√2
Step-by-step explanation:
Let the side of the square be x
If the diagonal is 12m (hypotenuse), then;
x^2 + x^2 = 12^2
2x^2 = 144
x^2 = 144/2
x^2 = 72
x = √72
x = √36*2
x = 6√2
Perimeter of the square garden = 4x
Perimeter of the square garden = 4(6√2)
Perimeter of the square garden = 24√2

Ismael has a set of 5 solar panels and Ben has a set of 6 smaller solar panels. Each set of panels produce the same amount of energy. 3 of Ismael's panels are on and producing energy. 4 of Ben's are on and producing more energy. Whose solar panels are producing more energy? Explain.
9514 1404 393
Answer:
Ben's
Step-by-step explanation:
If E is the amount of energy that each full set of panels produces, then ...
3 of Ismael's 5 panels produce 3/5E
4 of Ben's 6 panels produce 4/6E
We can compare these fractions when they have a common denominator.
3/5E = 18/30E . . . . energy from Ismael's panels
4/6E = 20/30E . . . energy from Ben's panels
18/30 < 20/30 . . . . so Ben's panels are producing more energy
