Find the missing angle or side. Round to the nearest tenth.

Mathematics
1 answer:
babymother [125]3 years ago

Answer:

x = 19.4

Step-by-step explanation:

For the 72-deg angle, 6 is the adjacent leg. x is the hypotenuse. The trig ratio that relates the adjacent leg to the hypotenuse is the cosine.

\cos A = \dfrac{adj}{hyp}

\cos 72^\circ = \dfrac{6}{x}

x \cos 72^\circ = 6

x = \dfrac{6}{\cos 72^\circ}

x = 19.4

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept → (0, b)

We have the point (0, 5). Therefore b = 5.

We have: y = mx + 5

Other point (3, 2). Substitute the coordinates of the point to the equation of the line:

2=3m+5     <em>subtract 5 from both sides</em>

-3=3m      <em>divide both sides by 3</em>

-1=m\to m=-1

<h3>Answer: f(x) = -1x + 5 = -x + 5</h3>

The amounts of Cathy’s last six clothing purchases were $109, $72, $99, $15, $99, and $89. For each question, choose the mean, m
lisov135 [29]

Answer:

The mean value = $80.5

Step-by-step explanation:

The value of her last six spendings are $109, $72, $99, $15, $99, and $89.

For the mean.

Mean = Total spendings/number

Mean =483/6

Mean = $80.5

For the median.

Lets arrange it in ascending order

$15 ,$72, $89, $99, $99, $109

The middle values are two.

Median = (89+99)/2

Median = 188/2

Median = $94

For the mode

$15 ,$72, $89, $99, $99, $109

Highest occuring is $99 with two frequencies.

To convince her parents that she needs an increase in allowance she would show them the bigger spendings .

So the least value on the list it's mean value which is $80.5.
