Flura [38]

Answer:

She will earn $85 in 10 hours.

In the number 15.2201 how does the value of 2 in the tenths place compare to the value of the 2 in the hundredths place
lakkis [162]

Answer:

The 2 in the hundreths is 10% of the 2 in the tenths

Step-by-step explanation:

We are given the number 15.2201

#The value of 2 in the tenths:

0.2

#The value of 2 in the hundredths:

0.02

The difference of the 2 in the tenths and in the hundredths is:

=2_t-2_h\\\\=0.2-0.02\\\\=0.18\\\\\#2_h \ as \ a \ \% \ of \ 2_t\\=\frac{2_h}{2_t}\times 100\%\\\\=\frac{0.02}{0.2}\times100\%\\\\2_h=10\% \ of\  2_t

Hence, the difference between the 2 in the tenths  minus 2 in the hundreths is 0.18, 2 in the hundreths is 10% the 2 in the tenths.

suppose the mean 40 yard dash time of a perfessional football player is 4.41 seconds with a standard deviation of 0.15 seconds.
I am Lyosha [343]
The percent of runners between these two times is 47.72.

We find the z-scores associated with each end of this interval using the formula
z=(X-μ)/σ

For the lower end,
z=(4.11-4.41)/0.15 = -0.3/0.15 = -2

Using a z-table (http://www.z-table.com) we see that the area to the left of, less than, this score is 0.0228.

For the upper end:
z=(4.41-4.41)/0.15 = 0/0.15 = 0

Using a z-table we see that the area to the left of, less than, this score is 0.5000.

We want the area between these times, so we subtract:
0.5000-0.0228 = 0.4772

This corresponds with 47.72%.
