Answer:

N=+24,-24

Step-by-step explanation:

Well this is a quadratic equation and we can make further deductions using it's discriminant

b²-4ac=0

N²-4(1×144)=0

N²-576=0

N²=576

N=√576

N=+24,-24

Answer:

d) $x=5$

Go to station 10

Step-by-step explanation:

$-\left(1+7x\right)-6\left(-7-x\right)=36$

Expand:

$-1-7x+42+6x=36$

$-x+41=36$

Subtract 41 from both sides:

$-x+41-41=36-41$

$-x=-5$

Divide both sides by -1:

$\frac{-x}{-1}=\frac{-5}{-1}$

$x=5$

Answer:

469.42 ft²

Step-by-step explanation:

Law of sines;

w/sin27 = 38/sin40

w = sin27*38/sin40

w = 26.84 ft

Angle x;

∡X = 180 - 27- 40 = 113º

Area;

A = 0.5*(26.84)*(38)*sin(113)

A = 469.42 ft²

Step-by-step explanation:

The experimental probability is the probability based on previous outcomes, that is, the number of desired outcomes divided by the number of total outcomes.

While bowling with friends, Brandy rolls a strike in 57 out of 72 frames. What is the experimental probability that brandy will roll a strike the first frame of the next game?

Desired outcomes:

57 strikes

Total outcomes:

72 frames

Probability:

p = 57/72 = 0.7917

79.17% probability that brandy will roll a strike the first frame of the next game
