2.) Fill in the blank.
Montano1993 [528]

Answer:

E.) 1

Step-by-step explanation:

Firstly we will solve for L.H.S.

L.H.S. =Csc^2\theta

Since we know that Csc^2\theta is the inverse of Sin^2\theta.

So we can say that;

csc^2\theta=\frac{1}{sin^2\theta}

Now For R.H.S.

Cot^2\theta+1

Since we  can rewrite cot^2\theta as \frac{cos^2\theta}{sin^2\theta}.

Now we can say that the R.H.S. is;

\frac{cos^2\theta}{sin^2\theta}+1

Now we add the fraction and get;

\frac{cos^2\theta+sin^2\theta}{sin^2\theta}

Now according to trigonometric identity;

cos^2\theta+sin^2\theta=1

So, \frac{cos^2\theta+sin^2\theta}{sin^2\theta}=\frac{1}{sin^2\theta}

Here,

csc^2\theta=\frac{1}{sin^2\theta}   and     Cot^2\theta+1 = \frac{1}{sin^2\theta}<em>  </em>

L.H.S. = R.H.S.

Hence csc^2\theta=cot^2\theta+1

zloy xaker [14]

Answer:

Mean: 169.4

Median: 171

Mode: 181

Step-by-step explanation:

I first sorted the numbers by value, least to greatest.

145 147 153 153 167 170 170 172 181 181 181 182 185 185

We can see that 181 occurs the most, 3 times, so it's the mode.

The median of this set will be the middle number(s).

When we take away 6 numbers from both sides we are left with 170 and 172, and the mean of these two numbers is 171. So the median is 171.

We can add all the numbers and divide by 14 to get the mean.

147+153+170+172+185+181+182+185+181+170+181+167+153+145=2372\\\\2372\div14\approx169.4

Hope this helped!
