Step-by-step explanation:

Hey there!!

It 's so simple.

You remember common property of triangle. (i.e sum of interior angle of a triangle is 180°)

So,

77° + 31° + x = 180°

x + 108° = 180°

x = 180° - 108°

Therefore the measure of angle x is 72°.

Hope it helps....

One car traveled 248 and drove 5 mph slower than a second car which drove 268m / (les) . the cars were traveling for the same ,

Katyanochek1 [597]

Answer:

The first car is traveling at a speed of

s1=62 mi/hr.

The second car is traveling at a speed of s2=67 mi/hr.

Step-by-step explanation:

Let t be the amount of time the cars are traveling

s1=248/t and s2=268/t

We are told:

s1=s2-5

That is

248/t=268/t-5

⇒248=268- 5t

⇒5t=20

⇒t=4

s1=248/4=62

s2=268/4=67

In the last chapter, we looked at three outliers arising from a plot of Average Wind Speed by Month in the Hopkins Forest. Each

Aloiza [94]

Answer:

Step-by-step explanation:

Hello!

We have the information of the average wind speed for three months:

February:

Mean: 2.324

SD: 1.577

Otlier: 6.73 mph

June:

Mean: 0.857

SD: 0.795

Otlier: 3.93 mph

August

Mean: 0.63

SD: 0.597

Outlier: 2.53mph

Z= X - μ ~N(0;1)

$Z_{February}= \frac{6.73 - 2.324}{1.577}$

$Z_{Februar}= 2.793$ ≅2.79

$Z_{June}= \frac{3.93 - 0.857 }{0.795}$

$Z_{June}= 3.87$

$Z_{August}= \frac{2.53 - 0.63}{0.597}$

$Z_{Augus}= 3.182$ ≅ 3.18

Comparing the three Z-scores you can say that the strongest wind event was in June. The number obtained means that is the furthest one in relation to the mean.

If the first step in the solution of the equation 2x - 8 = 5x + 3 is "subtract 2x," then in the form of a paragraph, explain in

monitta

$x = \frac{-11}{3}$

Step-by-step explanation:

Here we have , If the first step in the solution of the equation 2x - 8 = 5x + 3 is "subtract 2x," then in the form of a paragraph, explain in complete sentences the next steps necessary to completely solve the equation for x. Let's solve this :

2x - 8 = 5x + 3

⇒ $2x - 8 = 5x + 3$

⇒ $(2x - 8)-2x = (5x + 3)-2x$ { subtract 2x from both side }

⇒ $0 - 8 = 5x-2x + 3$

⇒ $- 8 = 3x + 3$

⇒ $- 8 -3= 3x + 3-3$ { subtract 3 from both sides }

⇒ $- 11 = 3x + 0$

⇒ $- 11 = 3x$

⇒ $\frac{-11}{3} = \frac{3}{3} x$ { divide 3 from both sides }

⇒ $x = \frac{-11}{3}$
