vladimir1956 [14]

Answer:

Lowest score needed=4.92

Step-by-step explanation:

Using the standard normal distribution table we find the value of standard normal deviate corresponding to area of 15%

For area of 15% we have Z= -1.04

Thus we have

$Z=\frac{X-\overline{X}}{\sigma }\\\\\therefore X=\sigma Z+\overline{X}\\\\$

Applying values we get

$X=-1.04\times 2+7\\\\X=4.92$

Thus lowest score needed = 4.92

when the temperature is 68 F, the speed of sound in air is approximately 343 meters per second. Approximately how many kilometer

Digiron [165]

Hello!

Since we are given that the speed of sound in the air travels about 343 meters per second, we can multiply 343 meters per second by 5, and then we convert the meters to kilometers.

343 · 5 = 1715 meters per 5 seconds.

1000 meters are equal to 1 kilometer. So, we can divide 1715 by 1000 to convert meters to kilometers.

1715 / 1000 = 1.715

Therefore, the speed of sound in air is about 1.715 kilometers per 5 seconds.

Question NEEDS ANSWERING

labwork [276]

The numeric value of the given expression is as follows:

121/900.

<h3>Numeric value of expression</h3>

The expression is defined as follows:

$\left(-\frac{1}{3} + 0.6\left(-\frac{1}{2}\right) + 1\right)^2$

The parenthesis take precedence. If there are more than one parenthesis, the inside one takes precedence.

The fraction equivalent of 0.6 is of 3/5, hence:

$\left(-\frac{1}{3} + \frac{3}{5}\left(-\frac{1}{2}\right) + 1\right)^2$

Solving the internal parenthesis, the expression is:

$\left(-\frac{1}{3} - \frac{3}{10} + 1\right)^2$

The least common multiple of 3, 10 and 1 is of 30, hence:

$\left(-\frac{1}{3} - \frac{3}{10} + 1\right)^2 = \left(\frac{-10 - 9 + 30}{30}\right)^2 = \left(\frac{11}{30}\right)^2$

To find the square of the fraction, we find the square of the numerator and the denominator, hence the numeric value of the expression is:

121/900.

<h3>Missing information</h3>

The expression is:

$\left(-\frac{1}{3} + 0.6\left(-\frac{1}{2}\right) + 1\right)^2$
