Answer:

\frac{2}{25}

Step-by-step explanation:

Given expression,

\frac{\frac{2x-4}{30} }{\frac{15x-30}{18} }

=>\frac{\frac{2(x-2)}{30} }{\frac{15(x-2)}{18} }

We see that (x-2) is common in both numerator and denominator

hence canceling out we get:-

\frac{2*18}{30*15}=\frac{2}{25}

Answer=\frac{2}{25}

Triangle congruence and similarly (picture included) SAS, ASA, SSS, or AAS?
N76 [4]

Answer:

SAS

Step-by-step explanation:

SAS Postulate: "If two sets of corresponding sides on two triangles and there included angle are congruent, then the triangles are similar".

We see that line segments XY-ST and XZ-SR are congruent along with the included angles X and S. Therefore, we can justify that SAS fits the situation.

What is the point-slope form of a line that has a slope of 1/2 and passes through point (-7,2)
Daniel [21]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = \frac{1}{2} and (a, b) = (- 7, 2), thus

y - 2 = \frac{1}{2}(x + 7) ← in point- slope form

A state park has a normally distributed daytime temperatures in the month of June. The mean temperature is 75 Fahrenheit and the
vesna_86 [32]

Answer:

0.16

Step-by-step explanation:

This probability is the area under the standard normal curve to the right of 82.  Note that 82 is ONE standard deviation above the mean:  75 + 7 = 82.

According to the Empirical Rule, 68% of data lies within one standard deviation of the mean.  In other words, 34% lies between the mean and one standard deviation above the mean.  The remaining area under the standard normal curve is thus (100% - 68%), or 32%.  Half of that is 16%.  

The probability that the temperature is above 82, or above 1 standard deviation above the mean, is 16%, which we can also express as 0.16.

Alternatively, use a calculator with built-in statistical functions.  In this case the desired result is found by executing the following command:

normcdf(82, 10000, 75, 7).  The desired result is 0.1587, or approximately 0.16.
