How should the decimal point in 34.05 be moved to determine the product 34.05 × 10 to the power of 6?

Ray Of Light [21]

Answer:

The decimal point should be moved Six places to the right side because there are Six zeros in 10 to the power of 6.

Step-by-step explanation:

As we have to represent the number in the form of $10^{6}$ we need to move the decimal Six places towards left because there are Six zeros in $10^{6}$ i.e. 1000000. For this purpose we will add four zeros to the left of the number.

So the number in the format mentioned in question will look like -

0.00003405 × $10^{6}$ .

An operations analyst counted the number of arrivals per minute at an ATM in each of 30 randomly chosen minutes. The results wer

liraira [26]

Step-by-step explanation:

since Poisson distribution parameter is not given so we have to estimate it from the sample data. The average number of of arrivals per minute at an ATM is

$\hat{\lambda}=\bar{x}=\frac{\sum x}{n}=\frac{30}{30}=1$

So probabaility for $\mathrm{X}=1$ is

$P(X=1)=\frac{e^{-\lambda} \lambda^{x}}{x !}=\frac{e^{-1} \cdot 1^{1}}{1 !}=0.3679$

So expected frequency for $X=1$ is $0.3679^{*} 30=11.037$ (or $\left.11.04\right)$ .

Can someone help me on 64 67 68 and if you do you will get a lot of points

andre [41]

Answer: #64, A. #67, A. #68, C

Step-by-step explanation:

#64

0.96/6= 0.16

2.4/16= 0.15

32= 0.18

16 oz is the least

#67

100/20=5

3*5=15

SO, it's 15%.

#68

Divide

$430/43= $10

$594/54= $11

Andrew= $8

So, Darren makes the most.

siniylev [52]

If each ticket is $9.75, then you multiply $9.75 by how many tickets he's buying. In this case he's buying 3, so it's 9.75x3. The total for that is $29.25. You subtract $28.25 from $43 and that leaves him with $13.75
