Two triangles are said to be similar if they have all their angles equal and corresponding sides are in the same ratio.

Given the figure above, it can be seen that △JKL is a right triangle with the right angle at K.
Also, △KML is a right triangle with the right angle at M.
Obviously, angle K = angle M given that they are both right angles.
Also angle L = angle L by the reflexive property.

Therefore, △JKL ~ △KML by the AA similarlity


Similarly, it can be seen that △JMK is a right triangle with the right angle at M.
Also, △JKL is a right triangle with the right angle at K.
Obviously, angle M = angle K given that they are both right angles.
Also angle J = angle J by the reflexive property.

Therefore, △JMK ~ △JKL by the AA similarlity

Therefore, the similarlity statements that are true are △JKL ~ △KML and △JMK ~ △JKL

This lesson asked you to investigate what it means for data to fall within 1, 2, and 3 standard deviations from the mean in a va

s2008m [1.1K]

Answer:

The data in statistics is generally supposed to deviate or vary from the mean. Standard deviations of 1, 2, and 3 are commonly used to calculate variability according to the empirical norm. In a normal distribution, we estimate 68 percent, 95 percent, and 98 percent of the data to be within 1, 2, and 3 standard deviations of the mean, respectively. This implies that the given percentage of data will lie within an interval of less than or greater than the standard deviation. If the values within a given standard deviation from the mean are standardized, the z value will always be equal to or less than the given standard deviation.

We should look at a program that aims to help people get out of poverty by using the standard deviation principle. The aim of the program is to provide free seeds to poor people who have been suffering from low yields due to the use of local seeds. If we use the definition of one standard deviation of the mean, or 2 and 3, we will favor the majority of people, but we will leave the poorest people in society behind.

Find X such that f(x)=0 for f(x)= -2x^2-x

Leokris [45]

Answer:

$x=\{-\frac{1}{2} ,\:0\}$

Step-by-step explanation:

$f(x) =-2x^2 -x\\plug \: f(x) =0\\0= -2x^2 -x\\2x^2 + x = 0\\x(2x+1) = 0\\\therefore x =0 \: or \: 2x+1 = 0\\\therefore x =0 \: or \: 2x = -1\\\\\therefore x =0 \: or \: x = -\frac{1}{2} \\\\x=\{-\frac{1}{2} ,\:0\}$

Which equations could you use the division property of equality to solve?

julia-pushkina [17]

The equations are:

1. 2.35y = 4.70

2. k/3 = 17

3. 4 = 10w

4. 55x = 111

5. 8 = a/5

Answer:

the equations that apply are:

1. 2.35y = 4.70

3. 4 = 10w

4. 55x = 111

Step-by-step explanation:

We want to determine which if the equation we can use the division property of equality to solve.

1. 2.35y = 4.70

We can divide both sides by 2.35, so that

2.35y/2.35 = 4.70/2.35

y = 4.70/2.35

THIS WORKS

2. k/3 = 17

THIA DOESN'T WORK

3. 4 = 10w

dividing both sides by 10

4/10 = 10w/10

w = 4/10

THIS WORKS

4. 55x = 111

Divide both sides by 55

55x/55 = 111/55

x = 111/55

THIS WORKS

5. 8 = a/5

THIS DOESNT WORK
