You can prove these triangles congruent by their corresponding angles, <b=<a, <2=<1, and <c=<c. You can also prove that these triangles are congruent because they have sides of the same length.

It is proved by SAS postulate. (Side angle side)
They give you information on the angle, <1=<2.
If you see that two corresponding sides on the triangles are congruent as well, then you have your two sides and the angle to prove it congruent.

You can also prove it by ASA. which is the opposite (angle side angle) You prove that two corresponding angles are congruent, such as <b=<a and <1=<2, then you prove that one corresponding side is congruent on the triangles.

In basketball, Nicole makes 4 baskets for every 10 shots. If she takes 3 shots, what is the probability that exactly 2 of them w

melomori [17]

Answer:

0.288

Step-by-step explanation:

Calculation for what is the probability that exactly 2 of them will be baskets

In order for us to find the probability that exactly 2 of them will be baskets we would have to make use of binomial distribution using Microsoft Excel

P =4 baskets/10 shots=0.4,

x = 2

n = 3 shots

P(2)=BINOMIAL DISTRIBUTION(2,3,0.4,FALSE)

P(2)=0.288

Therefore the probability that exactly 2 of them will be baskets is 0.288

The formula T= 2pi sqrt(L/32) relates the time, T, in seconds for a pendulum with the length, L, in feet, to make one full swing

tester [92]

The length of pendulum is 2.485 feet

<h3>Solution:</h3>

Given that,

The formula T= 2pi sqrt(L/32) relates the time, T, in seconds for a pendulum with the length, L, in feet, to make one full swing back and forth

Therefore, the given formula is:

$T=2\pi \sqrt{\frac{L}{32} }$

We have to find the length of pendulum that makes one full swing in 1.75 seconds

So the modify the given equation to find "L"

$T=2\pi \sqrt{\frac{L}{32} }\\\\ \sqrt{\frac{L}{32} }=\frac{T}{2 \pi}\\\\\text{Taking square root on both sides }\\\\\frac{L}{32} = \frac{T^2}{4 \pi^2}\\\\L = \frac{T^2}{4 \pi^2} \times 32\\\\L = \frac{T^2}{\pi^2 } \times 8$

Substitute T = 1.75 seconds and $\pi = 3.14$

$L = \frac{1.75^2}{3.14 \times 3.14} \times 8\\\\L = \frac{3.0625}{9.8596} \times 8\\\\L = 2.485$

Thus length of pendulum is 2.485 feet approximately
