Answer:
x=7
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
Let's solve your equation step-by-step.
58=9x−5
Step 1: Flip the equation.
9x−5=58
Step 2: Add 5 to both sides.
9x−5+5=58+5
9x=63
Step 3: Divide both sides by 9.
9x/9 = 63/9
x=7

To begin a bacteria study, a petri dish had 2300 bacteria cells. Each hour since, the number of cells has
increased by 7.2%.
Lett be the number of hours since the start of the study. Let y be the number of bacteria cells.
Write an exponential function showing the relationship between y and t.
PLEASE HELP :)
Answers
Answer: [tex]y= 2300(1.072)^t[/tex]
Step-by-step explanation:
The exponential growth equation : [tex]y=A(1+r)^t[/tex] , where A=initial value, r= rate of growth , t= time.
Given: A = 2300, r= 7.2% = 0.072
Let t be the number of hours since the start of the study. Let y be the number of bacteria cells.
then, the exponential function showing the relationship between y and t will be:
[tex]y= 2300(1+0.072)^t\\\\\Rightarrow\ y= 2300(1.072)^t[/tex]

what is 30% as a fraction in simplest form and as a decimal to the nearest hundredtgh
Answers
Answer:
fraction-3/10
decimal-.3
Answer:
Step-by-step explanation:
There are a few ways you could look at this, but this is the way that I prefer:
A percent is essentially already a fraction out of 100. 100% = 1. Therefore, 30% = [tex]\frac{30}{100}[/tex].
To simplify this, divide the top and the bottom by 10. This equals [tex]\frac{3}{10}[/tex]. Because 3 is a prime number and 10 is not divisible by 3, this is completely simplified.
To find the percent of any fraction, the easiest way is to simply divide the top by the bottom.
3/10 = 0.3
This is your final answer, as there is no number in the hundredth place or beyond to concern yourself with.

The mean is 1.95 and the standard deviation is 2.41 for the given distribution.
What is the standard deviation?A standard deviation (σ) is a measure of the distribution of the data in reference to the mean.
The given data as :
Correct question (x) Probability
0 0.05
1 0.20
2 0.50
3 0.25
In this scenario, we must calculate the mean, which is the product of the correct question and the probability. The mean will then be subtracted from the correct question. multiply the difference between the correct question and the mean by probability. This indicates the pay variance. off's The standard deviation of the distribution is given by taking the square root of the variance of the correct question.
Mean = 0 × 0.05 + 1 × 0.20 + 2 × 0.50 + 3 × 0.25
Mean = 1.95
Variance = (0 - 1.95)² + (1 - 1.95)² + (2 - 1.95)² + (3 - 1.95)²
Variance = 3.8025 + 0.9025 + 0.0025 + 1.1025
Variance = 5.81
Standard deviation = √(Variance)
Standard deviation = √(5.81)
Standard deviation = 2.41
Thus, the mean is 1.95 and the standard deviation is 2.41 for the given distribution.
