Answer:

6758

Step-by-step explanation:

Number of steps in Monday = 8565 steps

Number of steps in Tuesday = 14707 steps

Number of steps in Wednesday = 15323 steps

Number of steps in Thursday = 9788 steps

Number of steps in Friday = 12482 steps

Formula for range = Highest value – Lowest value

Here, highest value = 15323 and lowest value = 8565

Range of the number of steps = 15323 – 8565 = 6758

Hence, range of the number of steps is 6758 steps.

Suppose the sediment density (g/cm3 ) of a randomly selected specimen from a certain region is known to have a mean of 2.80 and

Irina18 [472]

Answer:

0.918 is the probability that the sample average sediment density is at most 3.00

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 2.80

Standard Deviation, σ = 0.85

Sample size,n = 35

We are given that the distribution of sediment density is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

Standard error due to sampling:

$=\dfrac{\sigma}{\sqrt{n}} = \dfrac{0.85}{\sqrt{35}} = 0.1437$

P(sample average sediment density is at most 3.00)

$P( x \leq 3.00) = P( z \leq \displaystyle\frac{3.00 - 2.80}{0.1437}) = P(z \leq 1.3917)$

Calculation the value from standard normal z table, we have,

$P(x \leq 3.00) = 0.918$

0.918 is the probability that the sample average sediment density is at most 3.00

Ben writes the number 74,443. The value of the digit 4 in the hundreds place is 10 times the value of the digit 4 is what place

Minchanka [31]

Place Value Going to Left of Decimal:

Decimal
Ones
Tens
Hundreds
Thousands
Ten-Thousands

The middle 4 in 74,443 is in the hundreds place. The 4 next to the 3 is in the tens place.

The 4 in the tens place is worth 40. 40 * 10 would equal the 400 in the hundreds place.

ANSWER: tens place

Hope this helps! :)
