Jon eats more than 1 apple; Jon eats 3 apples.


Jon eats 4 apples; Jon eats 1 apple.


Jon eats 2 apples; Jon eats more than 2 apples.


Jon eats 2 apples; Jon eats 4 apples.

Answers

Answer:

Jon eats 2 apples; Jon eats more than 2 apples.

Step-by-step explanation:

Mutually exclusive events are events which have no common element between them.  They are completely disjoint and the intersection would be a null set

Hence probability for the intersection of mutually exclusive events =0

Here we are given 4 options to select.

Jon eats more than 1 apple; Jon eats 3 apples.

These two are not mutually exclusive as eating 3 apples includes eating 1 apple.

Jon eats 4 apples; Jon eats 1 apple.

These two are not mutually exclusive as eating 4 apples includes eating 1 apple.

Jon eats 2 apples; Jon eats more than 2 apples.

These two are mutually exclusive since he cannot eat 2 applies exactly and also more than 2 apples

Jon eats 2 apples; Jon eats 4 apples.

These  two are not mutually exclusive as eating 4 apples includes eating 2 apple.

Hence correct answer is

Jon eats 2 apples; Jon eats more than 2 apples.

The lowest common denominator for the fractions 8/64 and 8/32 is ?

Answers

Final answer:

The lowest common denominator for the fractions 8/64 and 8/32 is 32. This is found by identifying 32 as the least common multiple of the denominators 64 and 32, allowing both fractions to be expressed with the same denominator.

Explanation:

Finding the Lowest Common Denominator

To find the lowest common denominator (LCD) for the fractions 8/64 and 8/32, you must identify the smallest number that both denominators can divide into without leaving a remainder. Both 64 and 32 can be divided by 32, so the LCD for these fractions is 32. It's important to understand that finding an LCD involves looking for the least common multiple (LCM) of the denominators. In this case, since 32 is a multiple of 64 (32x2=64), it serves as the LCM of 32 and 64, and consequently, the LCD of the fractions.

To further clarify, each fraction can be expressed with a denominator of 32. For 8/64, when we divide both the numerator and denominator by 8, we get 1/8. This fraction can then be converted to have a denominator of 32 through multiplication by 4 (1/8 * 4/4 = 4/32). Similarly, the fraction 8/32 is already expressed with the desired denominator.

By finding the LCD, it is easier to perform addition, subtraction, or comparison of fractions, as they will share the same denominator.

The lowest common denominator for the fractions [tex]\( \frac{8}{64} \) and \( \frac{8}{32} \) is \( \boxed{64} \).[/tex]

To find the lowest common denominator (LCD) for the fractions [tex]\( \frac{8}{64} \) and \( \frac{8}{32} \)[/tex], we need to determine the least common multiple (LCM) of the denominators 64 and 32.

Step 1: Find the prime factorization of each denominator:

[tex]- \( 64 = 2^6 \)[/tex]

[tex]- \( 32 = 2^5 \)[/tex]

Step 2: Determine the LCM by taking the highest power of each prime that appears in any factorization:

[tex]\[ \text{LCM} = 2^{\max(6, 5)} = 2^6 = 64 \][/tex]

Therefore, the LCD of the fractions [tex]\( \frac{8}{64} \) and \( \frac{8}{32} \) is \( 64 \).[/tex]

Step 3: Verify that ( 64 ) is indeed the LCD:

[tex]- \( \frac{8}{64} = \frac{1}{8} \)[/tex]

[tex]- \( \frac{8}{32} = \frac{1}{4} \)[/tex]

Both fractions can be rewritten with a denominator of ( 64 ):

[tex]- \( \frac{1}{8} = \frac{8}{64} \)[/tex]

[tex]- \( \frac{1}{4} = \frac{16}{64} \)[/tex]

Therefore, ( 64 ) is the lowest common denominator for[tex]\( \frac{8}{64} \) and \( \frac{8}{32} \).[/tex]

Thus, the lowest common denominator for the fractions [tex]\( \frac{8}{64} \) and \( \frac{8}{32} \) is \( \boxed{64} \).[/tex]

PLEASE explain this, I'm so lost. 25 points! What is the area of the base of the pyramid? Enter your answer in the box. Express your answer in radical form.

Answers

To find the area of the triangle shown we have to find the length of a and the base.

a can be found using the sine function. Recall sin = (opp)/(hyp)

Here [tex]sin 60 = \frac{a}{8} [/tex]
[tex] \frac{ \sqrt{3} }{2}= \frac{a}{8} [/tex]
[tex]2a=8 \sqrt{3} [/tex]
[tex]a=4 \sqrt{3} [/tex]

The base can be found using the sin of 30 degrees as this is a 30-60-90 right triangle.
[tex]sin30= \frac{b}{8} [/tex]
[tex]\ \frac{1}{2} = \frac{b}{8} [/tex]
[tex]b=4[/tex]

The area of the triangle in the picture is given by [tex]A=( \frac{1}{2} )bh= (\frac{1}{2})(4)( \frac{ \sqrt{3} }{2} )= \sqrt{3} [/tex].

The base of the pyramid is a hexagon which can be divided into 6 triangles each of which is double the area of the one we just found. So the area of the base = 2(area of the triangle we found)(6) = [tex]12 \sqrt{3} [/tex]

The answer is:

area of base =  [tex]12\sqrt{3}[/tex]

The area of a room is 396 square feet. The length is x+3, and the width is x+7 feet. Find the dimensions of the room

Answers

This is an odd problem. The length and width look like they should be interchanged. Anyway I'll solve it and we'll talk about the results.
(x +7) (x + 3) = 396
x^2 + 7x + 3x + 21 = 396
x^2 + 10x + 21 = 396 Subtract 21 from both sides.
x^2 + 10x = 396 - 21
x^2 + 10x = 375
x^2 + 10x - 375 = 0 This probably factors.
(x + 25)(x - 15)
x + 25 = 0
x = - 25 which makes no sense. Negatives do not describe room dimensions.
x - 15= 0
x = 15. this is fine.

x+3 = 15 + 3 = 18
x + 7 = 15 + 7= 22

Check
=====
Area = L * W = 18 * 22 = 496. It does check.
22 should be the length

18 should be the width.

Using the definitions of odd and even functions , explain why y=sin x+1 is neither odd or even

Answers

This is neither because none of these:
[tex]f(-x) = f(x)[/tex]
[tex]f(-x) = -f(x)[/tex]

I'm going to plug in π/2 to check if the odd and even function definition work for this problem or not. Let's do that:
[tex]f(-x) = f(x)[/tex]
[tex]f(- \frac{ \pi }{2} ) = 1 + sin(- \frac{ \pi }{2} ) = 1-1 = 0[/tex]
[tex]f(-x) = -f(x)[/tex]
[tex]f( \frac{ \pi }{2}) = 1+sin( \frac{ \pi }{2}) = 1+1 = 2 [/tex]

As we can see, 0 ≠ 2. Hence, the function is neither odd nor even.

Final answer:

The function y = sin x + 1 is neither even nor odd because it does not satisfy the conditions f(x) = f(-x) for even functions and f(-x) = -f(x) for odd functions after substitution and simplification.

Explanation:

An even function is defined as a function that satisfies the condition f(x) = f(-x), showing symmetry about the y-axis. An odd function, on the other hand, satisfies the condition f(-x) = -f(x), indicating symmetry about the origin. To determine if y = sin x + 1 is an odd or even function, we must check these conditions.

Applying the even function definition, we would expect sin(-x) + 1 = sin(x) + 1 which is not true because sin(-x) = -sin(x) and thus does not satisfy the required symmetry. When we apply the odd function test, we expect -(sin x + 1) = sin(-x) + 1, which also doesn't hold because -sin(x) - 1 does not equal sin(-x) + 1. Therefore, y = sin x + 1 is neither odd nor even.

A. SSS ​Similarity Theorem ​

B. ASA ​Similarity Theorem ​

C. AA ​Similarity Postulate ​

D. SAS ​Similarity Theorem

Answers

D) or SAS theorom hope this helps!

Answer:

The correct option is D.

Step-by-step explanation:

In triangle △JKL,

[tex]\frac{JK}{KL}=\frac{30}{50}=\frac{3}{5}[/tex]

In triangle △MKN,

[tex]\frac{MK}{KN}=\frac{15}{25}=\frac{3}{5}[/tex]

In triangle △JKL and △MKN

[tex]\frac{JK}{KL}=\frac{MK}{KN}[/tex]

[tex]\angle JKL=\angle MKN[/tex]                       (Vertically opposite angles)

Since two sides are proportional and an inclined angle is congruent, so by SAS theorem of similarity we get

[tex]\triangle JKL=\triangle MKN[/tex]

Therefore option D is correct.

In the United States, the mean average height of adult women is approximately 65.5 inches, with a standard deviation of 2.5 inches. If height is normally distributed,what percent of the women in this country are between 63 and 70.5 inches tall?

Answers

z = (x - mean) / SD
The z-score for x = 63 is: z = (63 - 65.5) / 2.5 = -1
The z-score for x = 70.5 is: z = (70.5 - 65.5) / 2.5 = 2
Therefore we need the probability that -1 < z < 2. This is equivalent to the probability that z < -1, subtracted from the probability that z < 2. From z-tables, we find that this is equal to 0.9772 - 0.1587 = 0.8185. This means that 81.85% of women's heights fall within this range.

Step 2: Write a meaningful mathematical equation using the sentence given

Step 3: Solve the equation by Performing reverse operation by Undoing whatever is done to the variable. Solving means find the value of the variable which will make the equation TRUE.

Applying the concept:

The probability that a randomly selected game from the season was played by the wolves given that it was a loss is 1/5.

What is probability?

It is the chance of an event to occur from a total number of outcomes.
