A virus reproduces by dividing into two, and after a certain growth period, it divides into two again. As the virus continues to reproduce, it will continue to divide in two. A scientist is doing experiments with a new strain of Corona virus. She starts with 5 viruses in a petri dish. How many viruses will be in the system AFTER 10 divisions? After how many division will there be 81,920 viruses?

S-7< 3 i need answering this problem someone asap answer

Polynomial that can be factored as (3x-4)(3x+4)

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
