A factory robot recently examined some bulbs, of which 4 were flawed and 26 were not. Considering this data, how many flawed bulbs would the robot be expected to find in a batch of 15 bulbs?
Answer:
2
Step-by-step explanation:
Given that:
Flawed bulbs = 4
Not flawed = 26
Total examined = (flawed + not flawed)
Total examined = (4 + 26) = 30
P(flawed) = flawed / total
P(flawed) = 4 / 30 = 0.1333333
If 15 is examined :
Expected number of flawed bulbs :
(4/30) * 15 = 2

There are GCF of two numbers is three and the LCM is 180. If one of the numbers is 45,what is the other number ?
Answer:
The other number is 12
Step-by-step explanation:
There are GCF of two numbers is three and the LCM is 180. If one of the numbers is 45,what is the other number ?
Let us represent the other number as x
There are GCF of two numbers is three and the LCM is 180.
Therefore:
45 × x = 3 × 180
45x = 3 × 180
x = 3 × 180/45
x = 12
Therefore, the other number is 12

Step-by-step explanation:
Carlos and Lily want to know the combined amount of money they made last week. They both made $12 per hour, but Carlos also made a $35 bonus. Carlos says the combined amount is 12C + 35 + 120 where Cis the number of hours he worked, and L is the number of hours Lily worked. Lily says the combined amount is 12(C+ L) + 35. Who is right? Explain.
Answer:
Lily is rightStep-by-step explanation:
Carlos made:
12C + 35Lily made:
12LTogether they made:
12C + 35 + 12L = 12(C + L) + 35Lily is right. We don't know what 120 means in Carlos's equation, he should put 12L for Lily.

Graph the image of the figure using the transformation given.
(its multiple choice!)
The original image undergoes reflection across x=-3.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
In the given graph DEFG is the original image.
D'E'F'G' is the new image after the transformations applied.
A reflection is defined by the axis of symmetry or mirror line. In the above diagram, the mirror line is x = -3.
Under reflection, the shape and size of an image is exactly the same as the original figure.
This type of transformation is called isometric transformation.
Hence, the original image undergoes reflection across x=-3.

A class of 25 children is having a pizza party. Each child will eat 3/8 of a pizza. How many pizzas do they need to order?
A. 8 pizza pies at 10 pc. per pie = 80 available pieces
B. Let X be the number of children. Number of pieces eaten = 5 per child = 5X.
c. 22 pieces are left over.
D. Combine line A and line C. Total number of pieces eaten = 80 original minus 22 left over. Result 58 pieces were eaten by X children: 58 = 5X.
E. Solve the equation 58 = 5X by dividing both sides by 5.
WHOOPS! Is this a trick question? Solving the above results in the answer that there are 11.6 children at the party. Hmmm. That 0.6 child is a question mark for me.
Looks like someone miscounted the pizza slices. Or omitted some pertinent information. But, I’m sure there is a logical answer.
Answer:
10 pizzas
Step-by-step explanation:
To find the answer for this question you need to multiply 3/8 by 25.
3/8 * 25 = 9.375
You can't buy .375 of a pizza so you round it up and get 10.

Alguien que me ayude a calcular la medida de un angulo central interno y externo de un heptagono { interno y externo]
Responder:
suma de ángulos interiores = 900 °
Suma de ángulos exteriores = 360 °
Explicación paso a paso:
Un heptágono es un polígono de 7 lados:
Para cualquier polígono con n lados:
El ángulo exterior del polígono suma 360 °
Por lo tanto, la medida de cada ángulo central de un heptágono es:
Suma de ángulos exteriores / número de lados
360 ° ÷ 7
= 51,43 °
El ángulo interior de un polígono se obtiene mediante la relación:
(n - 2) 180 °
Heptágono tiene 7 lados:
(7 - 2) 180 °
5 (180 °)
= 900 °
Por tanto, suma de ángulos interiores = 900 °
Suma de ángulos exteriores = 360 °

$420 is divided between A, B and C. B receives $20 less than A, and C receives half as much as A and B together. how much does each receive?
Also could you explain the answer?
Answer:
A = $150
B = $130
C = $140
Step-by-step explanation:
Let the amount received by a be $x
b receives $20 less than a;
we have that;
b = x - 20
c receives half of Sum A and B
c = (x + x-20)/2
c = (2x-20)/2
c = x - 10
Add all and it gives 420
x - 10 + x -20 + x = 420
3x -30 = 420
3x = 420 + 30
3x = 450
x = 450/3
x =$150
a = 150
b = x - 20; 150 - 20 = 130
c = x-10
c = 150-10
c = $140
