Johnny stated "All prime numbers are odd." Charlene responded, "I can demonstrate that your statement is false."Which explanation is sufficient to prove Johnny's statement is false?

Answer choices are
A)Many prime numbers have a difference of two, such as 5 and 7, 11 and 13, and 41 and 43.

B)The numbers 15, 35, 21, are all odd, but not prime numbers.

C)There could be a very large number that is even and prime.

D)The number 2 is a counterexample.

Answers

Answer 1

Answer:

Only number 2 is prime and even number.

Option D is correct.

Prime and even number :

A prime number is a whole number greater than 1 whose only factors are 1 and itself.

A factor is a whole number that can be divided evenly into another number.

The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29.

An even number is a number that can be divided into two equal groups.

An odd number is a number that cannot be divided into two equal groups.

From above definition of numbers, It is observed that 2 is prime and even number.

Thus, statement "All prime numbers are odd " is false.

Answer 2

Answer:

$\text{Hello There!}$

$\bf\text{All prime numbers are ultimately odd besides 2 because it is a factor.}$

$\text{Therefore, he would be close, but incorrect at some extent.}$

Len's recipe for blueberry muffins calls for 110.25 g of brown sugar for the muffin batter and an additional 55.45 g of brown sugar for the topping.Len wants to make 4.5 batches of muffins.

How much brown sugar will Len need?

Answers

110.25+55.45= 165.70(one muffin)
That means that we need to multiply 165.70 by (16.4)+8

Which simplified is 72x165.70= 11.930.4
which is the equivalent of 11kg 930 grams and 40 milligrams

Letitia is making a pizza that needs to cover 36 square inches. Give two possible sets of dimensions (length and width) that will give Letitia's pizza the desired area. Also give the perimeter for each set.

Answers

ok so assuming you ahve a rectangle (since you gave legnth and width)

area=legnth times width
perimiter=L+L+W+W=2L+2W=2(L+W)

area=36
some factors are
6 and 6
4 and 9
3 and 12
2 and 18
1 and 36
those are only whole numbers, but tat is for ease

so add and mutliplyby 2 (preimiter

6 and 6, P=2(6+6)=24
4 and 9, P=2(4+9)=26
3 and 12, P=2(3+12)=30
2 and 18, P=2(2+18)=40
1 and 36, P=2(1+36=74

The graph of f (x)=√x is transformed to create thegraph of g (x)= -2√x+6. Which of these describes a
transformation used to create the graph of g?

Answers

The transformation used to create the graph of g(x) from the graph of f(x) is a vertical and horizontal transformation.

The "-2" in the equation of g(x) reflects a vertical stretch by a factor of 2, which causes the graph to become narrower and steeper than f(x).

The "+6" in the equation of g(x) reflects a vertical shift upward by 6 units, which moves the entire graph of g(x) upward by 6 units.

Therefore, the transformation used to create the graph of g(x) from the graph of f(x) is a vertical and horizontal transformation.

(-4,7),(-6,-4) find slope

Answers

To find the slope, plug the two coordinate pairs into the formula
m = $(y_2 - y_1)/(x_2 - x_1)$ . M will represent the slope.

M = $(y_2 - y_1)/(x_2 - x_1)$ Substitute in the x and y values
M = $((-4) - 7)/((-6) - (-4))$ Subtract
M = $(-11)/(-2)$ Simplify
M = $(11)/(2)$

The slope is $(11)/(2)$
