The amount of bacteria cells that would be in the petri dish after 30 minutes is 73.3
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let y represent the number of cells after x minutes, hence:
y = 4.2(1.1)ˣ
After 30 minutes:
y = 4.2(1.1)³⁰ = 73.3
The amount of bacteria cells that would be in the petri dish after 30 minutes is 73.3

Answer:
D: 7p - 4
Step-by-step explanation:
If we have 7 pizzas and each one is worth p 7p would equal the cost of all seven. Then subtract 4 from the total.
Let the number be a ...
i.e ,70% of a =126 ..
=> 70/100 X a =126
=>7/10 a =126
=>7 a = 126 X 10
=>7 a= 1260
=>a = 1260/7
a = 180 ..
Hope it helps !!!
In order the numbers are 20, 29, 32, 37, 42.
So that means the median is 32. In order for the median to stay the same one of the three data values must be 32 as well as adding a number to each side of the ends. One 32 or less another 32or more.
The mean right now is: 20+29+32+37+42=160 and there are 5 values.
Mean: 160/5=32
For it to increase by 10 it has to be 42.
extra 3 numbers I used were 31, 32, & 113 (those are your answer)
A correlation coefficient of -1 shows a perfect negative correlation
