Which of the following is a biconditional statement?
Question 17 options:

A)

If x ≠ 5 then x2 ≠ 25

B)

If x2 = 25, then x = 5 or x = –5

C)

x = 5 if x2 = 25

D)

x = 5 if and only if x + 5 = 10

Answers

It is D

I just took the test and got it right

The biconditional statement is x = 5 if and only if x + 5 = 10.

Option D is the correct answer.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Biconditional statement.

This means,

The statement and its converse are both true.

Now,

x = 5 if and only if x + 5 = 10

This shows that both the statement and its converse are true.


Thus,

x = 5 if and only if x + 5 = 10 is a biconditional statement.

From the graph, [tex]y=mx+b[/tex] and m < 0 (The slope right here is less than 0.)

That means cut ( b ) and ( d ) choice, they both are wrong.

Now look at ( a ) and ( c ).

For ( a ) It's just f(x) = -2x but the graph that's shown here intercepts y-axis at (0,2).   f(x) = -2x is just slope and intercepts y-axis at (0,0)

So the answer is ( c )

Consider random samples of size 900 from a population with proportion 0.65 . Find the standard error of the distribution of sample proportions.

Answers

Answer:

The value is [tex]\sigma_{p} = 0.022[/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  n  =  900

    The population proportion is  [tex]p = 0.65[/tex]

Generally the standard error of the distribution of sample proportion is mathematically represented as

       [tex]\sigma_{p} = \sqrt{\frac{ p(1 - p)}{ n} }[/tex]

=>     [tex]\sigma_{p} = \sqrt{\frac{ 0.65 (1 - 0.65 )}{ 900} }[/tex]

=>     [tex]\sigma_{p} = 0.022[/tex]

A spinner is divided into eight equal-sized sections, numbered from 1 to 8, inclusive. What is true about spinning the spinner one time? Select three options. S = {1, 2, 3, 4, 5, 6, 7, 8} If A is a subset of S, A could be {1, 2, 3}. If A is a subset of S, A could be {7, 8, 9}. If a subset A represents spinning a number less than 4,then A = {1, 2, 3, 4}. If a subset A represents the complement of spinning an odd number, then A = {2, 4, 6, 8}.

Answers

Answer: A, B, and E

Step-by-step explanation:

The true statements are (A) A could be {1, 2, 3} and (B) A could be {1, 2, 3, 4}, where A  is a subset of S

How to determine the true statements?

The sample space is given as:

S = {1, 2, 3, 4, 5, 6, 7, 8}

The possible subsets of S are as follows:

Even numbers = {2,4,6,8}Odd numbers = {1,3,5,7}Any number or group from 1 to 8, inclusive

Using the above highlights, the possible set of A are:

A could be {1, 2, 3}. A = {1, 2, 3, 4}.

Hence, the true statements are (A) and (B)

A (1,-3)

Step-by-step explanation:

it is asking where on the graph is each point. it even gives you where it is located.

The coordinates of the triangle A"B"C" are A"(3, 2), B"(-1, 4) and C"(2, 0).

From the given graph, the coordinates of triangle ABC are A(1, -3), B(5, -1) and C(2, -5).

1) We know that, the reflection of point (x, y) across the y-axis is (-x, y).

Here,

A(1, -3)→A'(-1, -3)

B(5, -1)→B'(-5, -1)

C(2, -5)→C'(-2, -5)

2) The transformation with <4, 5> are

A'(-1, -3)→A"(-1+4, -3+5)

= A"(3, 2)

B'(-5, -1)→B"(-5+4, -1+5)

= B"(-1, 4)

C'(-2, -5)→C"(-2+4, -5+5)

= C"(2, 0)

Therefore, the coordinates of the triangle A"B"C" are A"(3, 2), B"(-1, 4) and C"(2, 0).

How are rates ratios and proportions used in careers in the medical field 4th Grade - RI.4.530 Seconds of Fuel - by Theresa BakerIn July 1969, three astronauts blasted off for the Moon. Their goal was not only to land on the Moon but also to walk on its surface. The journey from Earth to Moon was quiet, and the astronauts were patient and calm during the trip. The landing, however, would be quite exciting. After getting near the Moon, the landing ship, named Eagle, separated from the command ship. The command ship then remained in orbit around the Moon. During the landing ships descent to the Moon, the astronaut flying the ship made an announcement. Astronaut Neil Armstrong said, The Eagle has wings. He meant that the landing ship was flying well and doing its job. As the Eagle began its final approach, alarms sounded. By now, fuel was running low. Looking out the window, Armstrong realized the terrain was not good for landing. The problem was that it was rocky and dangerous. The landing site was supposed to be smooth. There was less than a minute of fuel left for a landing. If they ran out, the Eagle would be forced to cancel its flight and go back to the command ship. Armstrong had to decide how to meet this challenge. Should he call off the landing? Or should he look for another landing spot? He quickly chose to fly the ship to another area. Just seconds later, the ship landed in an area of the Moon called the Sea of Tranquility. There were only about 30 seconds of fuel left. Armstrong announced, The Eagle has landed."This questions has two parts. Answer part A, then answer Part B. Part AIn paragraphs 1 and 2, the author describes events in time order.
