Answer 1
Answer:

Answer:

Definition of congruence

Step-by-step explanation:

According to this

If two sides are equal then they are ought to be congruent.

Here

CD is equal to EF

  • It means both have same lengths

Hence they are congruent
Answer 2
Answer:

Final answer:

Based on the Definition of Congruence in mathematics, if two line segments are of equal lengths, then they are said to be congruent. So if CD = EF, then CD is congruent to EF (CD ≅ EF).

Explanation:

In this context, if CD = EF, then CD is indeed congruent to EF, written as CD ≅ EF.

This is based on the Definition of Congruence in mathematics, specifically geometry, which states that two objects (in this case, line segments) are congruent if they have the exact same size and shape, or, for line segments, the same length. So, if the lengths of two line segments are equal (CD = EF), then they are congruent (CD ≅ EF).

Answers

Answer:

B

Step-by-step explanation:

Answer:

The answer is B, 11-6=5

Step-by-step explanation.

Since the range of both quartiles is 11 and 6. You would subtract both of these to get the answer. Which in this case, is 5.

What is a function?

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.

Given,

f(x)=2x-3

f(7) so put x = 7

f(7) = 2(7) - 3

f(7) = 11

Now,

f(-2) so put x = -2

f(-2) = -2×7-3

f(-2) = -17

Now,

f(-4) so put x = -4

f(-4)= -4×7-3

f(-4) = -31

Hence,The value of f(7) ,f(-2) and f(-4) will be 11 , -17 and -31 respectively.

Step-by-step explanation:

f(x)=2x-3

now,

f(7)=2× 7-3

=14-3

=11

f(-2)='-2×7-3

= -14-3

b= -17

f(-4)= -4×7-3

= -28-3

= -31

Suppose that a medical test has a 92% chance of detecting a disease if the person has it (i.e., 92% sensi- tivity) and a 94% chance of correctly indicating that the disease is absent if the person really does not have the disease (i.e., 94% specificity). Suppose 10% of the popu- lation has the disease. (a) What is the probability that a randomly chosen per- son will test positive

Answers

Answer:

14.6% probability that a randomly chosen person will test positive

Step-by-step explanation:

We have these following probabilities:

10% probability that a randomly selected person has the disease.

If a person has the disease, 92% probability of testing positive.

100-10 = 90% probability that a person does not have the disease.

If a person does not have the disease, 100-94 = 6% probability of testing positive.

What is the probability that a randomly chosen person will test positive

92% of 10% or 6% of 90%.

Then

p = 0.92*0.1 + 0.06*0.9 = 0.146

14.6% probability that a randomly chosen person will test positive
