Law of sines: 2.2 units 2.4 units 3.0 units 3.3 units

Arada [10]

Answer:

$RS=2.4\ units$

Step-by-step explanation:

The complete question is

What is the length of line segment RS? Use the law of sines to find the answer. Round to the nearest tenth.

see the attached figure to better understand the problem

step 1

Find the measure of angle S

Applying the law of sines

$\frac{QS}{sin(R)}=\frac{QR}{sin(S)}$

substitute the given values

$\frac{3.1}{sin(80^o)}=\frac{2.4}{sin(S)}$

Solve for sin(S)

$sin(S)=\frac{sin(80^o)}{3.1}(2.4)$

$S=sin^{-1}[sin(80^o)}{3.1}(2.4)]$

$S=49.68^o$

step 2

Find the measure of angle Q

Remember that the sum of the interior angles in any triangle mut b equal to 180 degrees

$m\angle Q+m\angle R+m\angle S=180^o$

substitute the given values

$m\angle Q+80^o+49.68^o=180^o$

$m\angle Q+129.68^o=180^o$

$m\angle Q=180^o-129.68^o$

$m\angle Q=50.32^o$

step 3

Find the length of segment RS

Applying the law of sines

$\frac{QS}{sin(R)}=\frac{RS}{sin(Q)}$

substitute the given values

$\frac{3.1}{sin(80^o)}=\frac{RS}{sin(50.32^o)}$

$RS=\frac{3.1}{sin(80^o)}{sin(50.32^o)}$

$RS=2.4\ units$

For math: Add: (there both fractions) 2/5+1/2

liubo4ka [24]

1. Find the Least Common Denominator (LCD) of $\frac{2}{5} , \frac{1}{2}$
Method 1: By Listing MultiplesList out all multiples of each denominator, and find the first common one.

5: 5,10
2: 2, 4, 6, 8,10

Method 2: By Prime FactorsList all prime factors of each denominator, and find the union of these primes.

5 : 5
2 : 2
Therefore, the LCD is 2 x 5 = 10
2. Make the denominators the same as the LCD

$\frac{2 * 2}{5 * 2} + \frac{1 * 5}{2 * 5}$

3. Simplify. Denominators are now the same

$\frac{4}{10} + \frac{5}{10}$

4. Join the denominators

$\frac{4+5}{10}$

5. Simplify

 $\frac{9}{10}$

Done (Fact: Decimal Form 0.9)

What is not true about unit rates?

nydimaria [60]

Answer:

One thing that is not true would be:

There isn't a 1 in a unit rate

Step-by-step explanation:

There is actually a 1 (specifically in the denominator) because the word unit means 1

Hope this helps :)

How will a high outlier in a data set affect the mean and median?

RUDIKE [14]

Answer:

B. distribution skewed to the right, mean pulled to the right, median not effected

Step-by-step explanation:

When a distribution is skewed to the right, it means that the data is positively skewed or has more positive numbers than negative numbers.

An outlier can affect the mean of a distribution since a high value outlier will make the mean be much higher than the median. In this case, since the distribution is positively skewed, a high outlier will pull the mean to the right (to higher positive values).
