The bacteria in a culture double every day. Which function can be used to find the number of bacteria n after d days if there are initially 75 bacteria?
On=2(75)
O n = 75(g)
On = 75(2)
On= (75)"
Answers
Answer:
n = 75(2)^d
Step-by-step explanation:
Mathematically, we have the general form of an exponential equation as follows;
y = I(1 + r)^x
where I is the initial value
r is the rate percentage
x is the number of time
From the question, the bacteria population doubles
This mean it increases by 100%
100% = 1
add this to the initial 1, and we have 2
Replace I with the number 75
And d represents the days
so we have;
n = 75(2)^d

(5 points) Part B: What is the probability the next driver using their turn signal that the police officer pulls over if the fifth driver? (5 points) (10 points)
Step-by-step explanation:
p = 0.78
1 - p = 0.22
P(x = 3)
Using the binomial distribution formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 3) = 5C3 * 0.78^3 * 0.22^2
P(x = 3) = 10 * 0.78^3 * 0.22^2
P(x = 3) = 0.2297

Rob is saving to buy a new MP3 player. For every $12 he earns babysitting, he saves $9. On Saturday, Rob earned $36 babysitting. How much money did he save?
Answers
Answer:
$27
Step-by-step explanation:
Set up a proportion where x is the amount of money he saved:
[tex]\frac{12}{9}[/tex] = [tex]\frac{36}{x}[/tex]
Cross multiply and solve for x:
12x = 324
x = 27
So, he saved $27
Which one should I pick?
Answers
Answer:
x = 7, y = 16
Step-by-step explanation:
From the diagram shown;
2x+5 = x+12
collect the like terms
2x-x = 12 - 5
x = 7
Similarly, y - 4 = x+5
y-4 = 7+5
y - 4 = 12
y - 12+4
y = 16
hence x = 7, y = 16

Calculate the area of triangles using two different methods. figures are now drawn to scale.
Answers
Answer:
the formula is base times hight divided by two so use the formula to sovle the problem
Step-by-step explanation:
The area of the triangles given are 52.5 feet² and 369 inches² respectively.
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
The basic formula to calculate the area of a triangle is,
Area = [tex]\frac{1}{2}[/tex] × base × height
1. Base = 12 + 3 = 15 feet
Altitude/height = 7 feet
Area = [tex]\frac{1}{2}[/tex] × 15 × 7 = 52.5 feet²
2. Calculating the area of two separate triangles and then adding it,
Area = ([tex]\frac{1}{2}[/tex] × 32 × 18) + ([tex]\frac{1}{2}[/tex] × 9 × 18)
= 288 + 81
= 369 inches²
Hence the area of the two figures is 52.5 feet² and 369 inches² respectively.
