PLZ HELP ASAP LAST SIMMILAR AND CONGRUENT TRIANGLES

JulsSmile [24]

Since Y is the right angle of the triangle LNT, LT is the hypotenuse of that triangle. We are going to use the Pythagorean equation to find the measure of LT:
$LT= \sqrt{LY^2+TY^2}$
$LT= \sqrt{5.2^2+3.9^2}$
$LT=6.5$

We can infer from our picture that triangles LNT and YNT are similar. And remember that in similar triangles the corresponding sides are proportional, so we can establish a proportion between sides LT and NT, and between sides LY and TY:
 $\frac{LT}{NT} = \frac{LY}{TY}$
$\frac{6.5}{NT} = \frac{5.2}{3.9}$
Solving for NT:
 $NT= \frac{(6.5)(3.9)}{(5.2)}$
$NT=4.88$

Now the perimeter of our rectangle LINT will be 2LT + 2NT.
 $2(LT)+2(NT)=2(6.5)+2(4.88)=22.76$ 

We can conclude that the perimeter of the rectangle LINT is 22.76 units

Assume a random variable x is normally distributed with mean = 90 and standard deviation = 5. Find the indicated probability.

nikklg [1K]

Answer:

16%

Step-by-step explanation:

The indicated probability is actually the area under the standard normal curve to the left of the mean. I used the function normalcdf( on my TI-83 Plus calculator to find this quantity:

normalcdf(-1000,85,90,5) = 0.1587.

Note #1: This quantity (area / probability) is the area to the left of 85.

Note #2: by the Empirical Rule, 68% of data lies within 1 s. d. of the mean, so the area between the mean (90) and the score (85) is half of 68%, or 34%. Subtracting this from 50% (the area to the left of the mean), we get 16%, which is roughly equivalent to the 0.1587 we got earlier.

How does starting with a different number change the diagram

frozen [14]

Starting with a different number changes the diagram because if you started with any other number, you would get different results.

Probability and Statistics

Rainbow [258]

Answer:

Step-by-step explanation: if you want to obtain the probability that x $\leq$ -3 , then you need to add the probability for the cases x=-3 and x=-5.

p=0.13+0.17= 0.3

answer=0.3

What is the value of one raised to any exponent

blondinia [14]

The value of 1 raised to any exponent would be 1 because no matter how many times you multiply 1 and 1, it will still be one. So 1 to the power of 200 would be one because you are multiplying 1 two-hundred times.

Final Answer: The answer would be one
