Answer:

x= 6

m∠PQS= 82°

m∠SQR= 59°

Step-by-step explanation:

m∠PQR= m∠PQS +m∠SQR

Since m∠PQR= 141°,

m∠PQS +m∠SQR= 141°

(13x +4)° +(10x -1)°= 141°

13x +4 +10x -1= 141

Simplify:

23x +3= 141

Minus 3 on both sides:

23x= 141 -3

23x= 138

x= 138 ÷23

x= 6

m∠PQS

= (13x +4)°

= [13(6) +4]°

= (78 +4)°

= 82°

m∠SQR

= [10(6) -1]°

= (60 -1)°

= 59°

Alternatively,

m∠SQR

= 141° -82°

= 59°

Answer:

x=6 . m<PQS=82 m<SQR=61 :)

Step-by-step explanation:

(13x+4) + (10x-1) = 141

combine like terms

23x+3=141

subtract 3 from both sides

23x=138

divide both sides by 23

x=6

substitute x into both original equations

m<PQS=13(6)+4

m<PQS=78+4

m<PQS= 82

m<SQR=10(6)+1

m<SQR=60+1

M<SQR=61

How are rate of change and slope related for a linear relationship?

ale4655 [162]

Hello! In slope-intercept form, y=mx+b. M is the slope and b is the y-intercept. The rate of change and slope are interchangeable, therefore, they both create a line through the slope-intercept form. Feel free to rate my answer Brainliest if I helped you!

A tiny but horrible alien is standing at the top of the Eiffel Tower (which is 324324324 meters tall) and threatening to destroy

DedPeter [7]

Answer:

A tiny but horrible alien is standing at the top of the Eiffel Tower (which is 324 meters tall) and threatening to destroy the city of Paris! A Men In Black agent is standing at ground level, 54 meters across the Eiffel square, aiming his laser gun at the alien. At what angle, in degrees, should the agent shoot his laser gun? Round your final answer to the nearest tenth

The agent shoot his laser gun at 80.5 degree.

Step-by-step explanation:

Given:

Height at which the horrible alien is standing = 324 m

Distance from the (tower) where the agent is = 54 m

According to the question:

Men In Black agent is aiming his laser gun to shoot the horrible alien.

Let the angle at which the agent shoot his gun be " Ф "

As from the situated depicted we can draw a right angled triangle.

Using trigonometric ratios:

tan (Ф) = opposite/ adjacent

In triangle OPQ .

The adjacent side = 54 m

The opposite side = 324 m

⇒ Plugging the values.

⇒ $tan(\phi) = \frac{opposite}{hypotenuse}$

⇒ $tan(\phi) = \frac{324}{54}$

⇒ $(\phi) = tan^-^1(\frac{324}{54})$

⇒ $\phi=80.53$

Nearest tenth it is 80.5 degrees.

So,

Men In Black must shoot the laser gun at an angle of 80.5 degrees.

According to a recent New York Times poll, 25% of the public have responded to a telephone call-in

ArbitrLikvidat [17]

Answer:

Probability that exactly two people out of a randomly chosen group of five people have responded to a telephone call-in poll is 0.264.

Step-by-step explanation:

We are given that according to a recent New York Times poll, 25% of the public have responded to a telephone call-in poll.

Also, five people have people have been randomly selected.

The above situation can be represented through binomial distribution;

$P(X = r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r};x=0,1,2,3,.......$

where, n = number trials (samples) taken = 5 people

r = number of success = exactly two

p = probability of success which in our question is probability that

public have responded to a telephone call-in poll, i.e; p = 25%

Let X = Number of people who have responded to a telephone call-in poll

So, X ~ Binom(n = 5, p = 0.25)

Now, probability that exactly two people out of group of five people have responded to a telephone call-in poll is given by = P(X = 2)

P(X = 2) = $\binom{5}{2} \times 0.25^{2} \times (1-0.25)^{5-2}$

= $10 \times 0.25^{2} \times 0.75^{3}$

= 0.264

Therefore, the probability that exactly two people out of a randomly chosen group of five people have responded to a telephone call-in poll is 0.264.
