Answer:

The result is 8.75 x10^8

Step-by-step explanation:

When you multiply numbers in scientific notation, you do the following:  

Multiply the base numbers normally:  

2.5* 3.5 = 8.75  

The exponents with base 10 are added and the base stays the same in the result:  

10^10x10^-2= 10^(10+(-2))=10^8.  

The answer is the multiplicaton of both 8.75*10^8.

8.75^8 when you multiply you add your exponents and when you divide you subtract your exponents

1. (Sec. 6.1) In a random sample of 80 components of a certain type, 12 are found to be defective. (a) Give a point estimate for
denis-greek [22]

Answer:

(a) 0.85

(b) 0.7225

Step-by-step explanation:

(a) The point estimate for the proportion of all such components that are not defective is given by the number of non-defective units in the sample divided by the sample size:

p=\frac{80-12}{80}\\p=0.85

The proportion is 0.85.

(b) Assuming that the sample is large enough to accurately provide a point estimate for the whole population, this can be treated as a binomial model with probability of success (non-defective part) p = 0.85. Since both components must be non-defective for the system to work, the probability of two successes in two trials is:

P(x=2) = 0.85^2\\P(x=2) = 0.7225

An estimate of 0.7225 for the proportion of all such systems that will function properly.

bogdanovich [222]
The information given requires you to rework the formula as :
distance÷time=rate

so then plug in values to get
5÷2=rate

and the answer will be 2.5 as your rate
