Answer:
she can buy 3 T-shirts
Step-by-step explanation:
200.00-87.96=112.04
112.04-30-30-30=22.04
Answer: 0.6827
Step-by-step explanation:
Given : The resistance of a strain gauge is normally distributed .
Population mean : 
Standard deviation : 
Let x be the random variable that represents the resistance of a strain gauge is normally distributed .
z-score : 
To meet the specification, the resistance must be within the range 100±0.7 ohms i.e. (99.3,100.7).
For x = 100.7

For x = 99.3

By using the standard normal distribution table, The proportion of gauges is acceptable is given by:-

Hence, the proportion of gauges is acceptable=0.6827
Answer:
-8xy
Step-by-step explanation:
The answer is interval or ratio. In interval level of measurement, the
distances between have attributes does have a meaning. The best example to be
used here is temperature. The
distance from 40-50 is like the distance from 70-80. While in <span>ratio level of </span>measurement,
there is constantly an absolute zero that is significant. Meaning, that you can
build a meaningful fraction (or ratio) with a ratio variable.
The <em><u>correct answer</u></em> is:
Box 2
Explanation:
In these expressions, x represents the width of the box. We are asked about widths greater than 1; let's us 1.1 as an example:
Box 1:
3(1.1⁵) = 4.83153
Box 2:
4(1.1⁵)-(1.1⁴) = 6.44204 - 1.4641 = 4.97794
With a difference as small as a tenth, the volume of box 2 is larger. The larger the difference in width, the larger the difference in volume, and the volume of box 2 will be larger every time.
