Answer:

7.8cos23 feet

Step-by-step explanation:

Which expression can be used to find AC

From the given diagram;

Hypotenuse = AB = 7.8ft

Adjacent to <A = AC

Using the SOH CAH TOA identity;

cos theta = adjacent/hypotenuse

cos 23 = AC/AB

cos 23 = AC/7.8

AC = 7.8cos23

AC = 7.8(0.9205)

Hence the measure of AC is 7.8cos23 feet

The point(3,7) is reflected in the y axis what are the coordinates now
lapo4ka [179]
When a point P(a, b) is reflected about the y-axis, the coordinates of the reflected point are P'(-a, b).

Thus, the reflection of point (3, 7) is (-3, 7), as shown in the picture.

The owners of an industrial plant want to determine which of two types of fuel (gas or electricity) will produce more useful ene
madreJ [45]

Answer:

d. H0: (\mu_e - \mu_g) = 0 vs. Ha: (\mu_e - \mu_g) \neq 0

Step-by-step explanation:

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".  

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".  

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".  

On this case the Management try to determine if there is a difference in the average investment/quad between using electricity and using gas. So this needs to be on the alternative hypothesis. And the complement of the alternative hypothesis would be on the null hypothesis.  

Null hypothesis :\mu_e = \mu_g

Alternative hypothesis: \mu_e \neq \mu_g

Or equivalently:

Null hypothesis :\mu_e - \mu_g = 0

Alternative hypothesis: \mu_e - \mu_g \neq 0

Other important thing is that on the alternative hypothesis we never can have the symbol equal.  

So on this case the best options is:

d. H0: (\mu_e - \mu_g) = 0 vs. Ha: (\mu_e - \mu_g) \neq 0
