From the given triangle in the photo, the lengths of the sides are 3m and a, the hypotenuse is c. One angle, opposite of 3m is given to be 50 degrees C. The right equation that would solve c is,
                                         sin (50 degrees C) = 3m / c
Thus, the answer is the first choice.

Answer:

Option (a) is correct.

Step-by-step explanation:

Given a right angled triangle with given dimensions.

We have to find an equation that can be used to solve for side c,

Consider the given triangle ABC,

We know for ∠B = 50° , we have perpendicular = 3 m and hypotenuse is c,

Trigonometric ratio that defines the relation between  perpendicular and  hypotenuse is Sine.

Using trigonometric ratio,

\sin\theta=\dfrac{Perpendicular}{ hypotenuse}

\sin 50^{\circ}=\frac{AC}{AB}

\sin 50^{\circ}=\frac{3}{c}

Thus, Option (a) is correct.

A group of pennies made in 2018 are weighed. The mean is approximately 2.5 grams
Hatshy [7]

Answer:

*  The mean (a measure of central tendency) weight value is the average of the weights of all pennies in the study.

* The standard deviation (a measure of variability or dispersion) describes the lowest and highest any individual penny weight can be. Subtracting 0.02g from the mean, you get the lowest penny weight in the group.

Step-by-step explanation:

Recall that a penny is a money unit. It is created/produced, just like any other commodity. As a matter of fact, almost all types of money or currency are manufactured; with different materials ranging from paper to solid metals.

A group of pennies made in a certain year are weighed. The variable of interest here is weight of a penny.

The mean weight of all selected pennies is approximately 2.5grams.

The standard deviation of this mean value is 0.02grams.

In this context,

*  The mean (a measure of central tendency) weight value is the average of the weights of all pennies in the study.

* The standard deviation (a measure of variability or dispersion) describes the lowest and highest any individual penny weight can be. Subtracting 0.02g from the mean, you get the lowest penny weight in the group.

Likewise, adding 0.02g to the mean, you get the highest penny weight in the group.

Hence, the weight of each penny in this study, falls within

[2.48grams - 2.52grams]

Three fourths of a number p less than two is five sixths of another number r plus five solve for r
maw [93]
r = -3/4p - 18/5 
(or you could put 3.6 or 3 3/5 instead of 18/5)

2 - 3/4p = 5/6r + 5 
-5                     -5
-3 - 3/4p = 5/6r
 /(5/6)       /(5/6) 
-18/5 - 3/4p = r 
-3/4p - 18/5 = r
