Researchers sampled 178 young women who recently participated in a STEM program. Of the 178 STEM participants, 110 were in urba

Answer:

Probability from Urban Area = $\frac{55}{89}$

Probability NOT from Rural Area = $\frac{83}{89}$

Step-by-step explanation:

Total 178

Urban 110

Suburban 56

Rural 12

Hence, probability of x is number of x divided by total.

So, probability that she is from an urban area = 110/178 = 55/89

And

probability NOT a rural area (means urban and suburban which is 110+56=166) = 166/178 = 83/89

Solve the equation<br> 121x ²+64=0

slava [35]

Hello there ^ _ ^

121x² + 64 = 0
121x² = 0 - 64
121x² = -64
x² = 64/121
Now take square root
x = +/-√-64/121

I hope this help!

Angle θ is in standard position and (−6,−3) is a point on the terminal side of θ. What is the exact value of csc θ in simplest f

bearhunter [10]

Answer:

$\displaystyle \csc\theta=-\frac{\sqrt{5}}{2}$

Step-by-step explanation:

Since $\displaystyle \csc\theta=\frac{1}{\sin\theta}=\frac{1}{\frac{\text{Opposite}}{\text{Hypotenuse}}}=\frac{\text{Hypotenuse}}{\text{Opposite}}$ , we need to find the hypotenuse given our corresponding opposite and adjacent lengths of -6 and -3 accounting for Quadrant III:
