A. 20
B. 15
C. 187
D. 13
Answers
Answer:
defective battery=200×1/13=15.3=15 is your answer
Number of expected defective batteries are option(B) 15
What is Probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
Given,
Probability that a battery is defective = [tex]\frac{1}{13}[/tex]
Total number of batteries = 200 batteries
Number of expected defective batteries = [tex]200(\frac{1}{13})[/tex] ≅15 batteries
Hence, the number of expected defective batteries are option (B) 15 batteries

Step-by-step explanation:
Given
General form of an Exponential distribution :
y = ab^x
a = initial amount = 3000000
b = growth factor = 2
x = period = 24 / 4 = 6
y = final amount ; after one day = 24 hours ; x = 24 /4 = 6
y = 3000000(2)^6
y = 3000000 * 64
y = 192,000,000

A shape is made of 9 right triangles of equal size and three identical rectangles.
Each rectangle measures 7 mm wide by 3 mm high. The rectangles are each
7 mm wide by 3 mm high. What is the total area, in square millimeters,
of the shape?
Answers
Answer:
The area of the figure is 157.5 square millimeters.
Step-by-step explanation:
Since a shape is made of 9 right triangles of equal size and three identical rectangles, and each rectangle measures 7 mm wide by 3 mm high, while the rectangles are each 7 mm wide by 3 mm high, to determine what is the total area, in square millimeters, of the shape, the following calculations must be performed:
Area of a rectangle: base x height
Area of a triangle: (base x height) / 2
7x3 = 21 = Rectangle area
7x3 / 2 = 10.5 = Triangle area
21 x 3 + 10.5 x 9 = 157.5
Thus, the area of the figure is 157.5 square millimeters.

Answers
Answer:
2x - y + 2 = 0 is the equation
y = 2x + 2 is the equation in slope-intercept form
Step-by-step explanation:
slope = (y₂ - y₁) / (x₂ - x₁)
slope = (6 - 8) / (2 - 3)
slope = -2 / -1
slope (m) = 2
equation through the points (3,8) and (2,6):
(y - y₁) / (y₂ - y₁) = (x - x₁) / (x₂ - x₁)
(y - 8) / (6 - 8) = (x - 3) / (2 - 3)
(y - 8) / -2 = (x - 3) / -1
-y + 8 = -2x + 6
2x - y + 2 = 0
slope-intercept form,
y = mx + c
y = 2x + 2

Find an

Note: the first term should be a(1).
Answers
Answer:
Step-by-step explanation:
a₁ = 37
a₂ = 74
Common difference d = a₂ - a₁ = 37
nth term = a₁ + (n-1)d
= 37 + (n-1)37
= 37n
Answer:
Below in bold.
Step-by-step explanation:
The common difference is 74-37 = 37.
nth term a(n) = a1 + (n - 1)d
= 37 + 37(n - 1)
= 37n.
