I may be the second one because the first one says 19 percent of the people who polled that are teachers prefer burgers. And the second one says 19 percent of the teachers polled prefer burgers, so I think it is the second answer.

Answer:

Step-by-step explanation:

First question:  19% of those who prefered burgers were teachers.  This is true.  We focus on the "Burgers" column and ignore the rest of the table.  

Second question:  19% of the teachers polled prefered burgers.  This is false.  If we look at the "teachers" line, we see that 6 teachers prefered pizza and 4 prefered burgers.  The percentage of teachers prefering burgers was 4 / (4+6), or 4/10, or 40%.

Third question (impossible to read):  19% of the people polled prefer ..... .

False.  That 19% does not pertain to the entire group of people polled.

Answer:

= [tex]\dfrac{1}{5^{9}}[/tex]

Step-by-step explanation:

When dividing values with exponents, we simply need to subtract the numerators exponent to the denominators exponent.

So we have:

[tex]\dfrac{5^{-6}}{5^{3} }[/tex]

= [tex]5^{-6 - 3}[/tex]

= [tex]5^{-9}[/tex]

Now since we have a negative exponent, we can get the reciprocal of the value to make it positive.

= [tex]\dfrac{1}{5^{9}}[/tex]

Answer:

The answer is 1 / 5^(9)

Step-by-step explanation:

We just need to divide both numbers and find the result

(5)^-6 / (5)^3

(5)^(-6-(3)) =

(5)^(-9) =

1 / 5^(9) = 5,120 .10^(-7)

your answer is option D

Step-by-step explanation:

Answer:

A) 0.2  

Step-by-step explanation:

From least to greatest, the data points are

6, 6, 6, 7, 7, 7, 8, 8, 8, 9

To find the mean, we find the sum of the data points and divide by the number of data points, 10.  The sum of the data points is

6+6+6+7+7+7+8+8+8+9 = 72

Dividing by 10, the mean is 72/10 = 7.2.

The median is the middle number in the set.  This is 7.

The difference between the mean and the median is

7.2-7 = 0.2.

Answer:

0.2

Among the given options, option C) 2/3 is a possible probability for event Q that is greater than 1/2. Therefore, the correct answer is C) 2/3.

If event Q is more likely to occur than event T and the probability of event T is 1/2, then a possible probability of event Q could be any value greater than 1/2.

Let's dive deeper into the concept of probability and explore why option C) 2/3 is a possible probability for event Q.

When we say that event Q is more likely to occur than event T, it means that the probability of event Q is greater than the probability of event T. In this case, we are given that the probability of event T is 1/2.

To find a possible probability for event Q, select a value greater than 1/2. Option C) 2/3 fits this criterion. It indicates that event Q has a probability of 2/3, which is greater than 1/2.

Complete question

Event Q is more likely to occur than Event T. If P(Event T) = 1/2, what is a possible probability of Event Q? A)1/4 B)1/2 C)2/3 D)It cannot be determined.

The possible probability of event q is  is  [tex]\(\frac{3}{4}\).[/tex]

Since event Q is more likely than event T, the probability of event Q must be greater than the probability of event T.

The probability of event T is [tex]\(\frac{1}{2}\),[/tex] so the probability of event Q must be greater than [tex]\(\frac{1}{2}\).[/tex]

This satisfies the condition that event Q is more likely than event T because [tex]\(\frac{3}{4}\) (or 0.75)[/tex] is greater than [tex]\(\frac{1}{2}\) (or 0.5).[/tex]

 It is important to note that there are infinitely many probabilities that are greater than [tex]\(\frac{1}{2}\)[/tex] and less than or equal to 1 (the maximum probability for any event).

However, the question asks for a possible probability, and [tex]\(\frac{3}{4}\) is[/tex] a valid example that meets the given criteria.

This question relates to the economic principle of a budget constraint. Jane can afford to purchase up to 5 pizzas with her budget, calculated via: Number of Pizzas = Total Budget / Unit Cost per Pizza.

The subject of this question is related to an economic principle of budget constraint in mathematics. Here, Jane's budget constraint is her total budget of $45, and the unit cost per pizza is $8. The budget works as a restriction that states how many pizzas Jane can afford to buy. The number of pizzas she can buy can be calculated as her total budget divided by the unit cost per pizza.

Therefore, the question is asking you to determine how many pizzas Jane can afford to buy with her budget of $45. Using the formula Number of pizzas = Total budget / Unit cost per pizza, we get: Number of pizzas = $45 / $8 = 5.625.

Since Jane can't buy a fraction of a pizza, she can purchase up to 5 pizzas with her available budget.

Step-by-step explanation:

x⁶ + x³ + 1 = 0

The only possible rational roots are ± 1.

Use synthetic division to see if either root is valid:

1 |  1     0     0     1     0     0     1

  |  ↓     1      1     1     2     2     2  

     1      1     1      2    2     2      3   ← Remainder ≠ 0 so not a factor

-1 |  1     0     0     1     0     0     1

  |  ↓    -1      1    -1     0     0     0  

     1     -1     1      0    0     0      1   ← Remainder ≠ 0 so not a factor

Since there are no real roots, all 6 roots must be imaginary (complex). You can graph the equation to confirm (see attached). None of the roots cross the x-axis so they are all imaginary.

Answer:

Option B True

Step-by-step explanation:

we know that

A function relates each element of a set  (input) with exactly one element of another set  (output)

1) "...each element..." means that every element in X (input)  is related to some element in Y (output)

2) "...exactly one..." means that a function is single valued. It will not give back 2 or more results for the same input

therefore

f(x) is a function

The equation that relates the number of cups brewed to the ounces of coffee remaining is necessary to determine the initial amount of coffee in the pack, which is not provided in the question.

The question does not provide the specific equation that describes the relationship between the number of cups brewed (x) and the ounces of coffee (y) remaining in the pack. However, the task is to determine how much ground coffee, in ounces, was in the full pack when Mr. Finch purchased it. To solve this, we would typically need to know how much coffee is used per cup and have an initial amount representing the full pack. If the equation was provided, we could use it to calculate the initial amount of the coffee. Without the equation, we cannot proceed with the calculation. Ensuring all critical information is provided in a word problem is crucial for solving it.

B) 25/100 • 64

C) .25 • 64

D) 64 divided by 25/100

E) 25 divided by 64/100

B and C i believe

The values that have the same value as 25% of 64 are Options B) 25/100 · 64 and C) .25 · 64, both yielding the correct value of 16 when calculated.

To find the same value as 25% of 64, we need to express 25% in different formats and apply it to 64. Option B) 25/100 · 64 translates the percent into a fraction, then multiplies by 64. Option C) .25 · 64 converts the percentage directly into a decimal, again multiplying by 64. Both expressions will yield the same result, which is the value of 25% of 64.

Options A), D), and E) do not give the correct value. A) is simply multiplication without considering the percentage, D) is incorrect because dividing 64 by a fraction is equivalent to multiplying by its reciprocal, and E) is an incorrect fraction division that does not represent 25% of 64.

Therefore, the correct answers are B) and C).

Answer:

The solutions of the equation are -41.8° , 0.0° , 41.8°

Step-by-step explanation:

∵ 3 sin²Ф - 2 sinФ = 0 is a quadratic function

∵ The domain of the function is -90° ≤ Ф ≤ 90°

- Lets take sinФ as a common factor

∴ sinФ (3 sinФ - 2) = 0

- Two terms multiplied by each other = 0

∴ One of them must be equal zero

∴ sinФ = 0 or 3 sinФ - 2 = 0

- If sinФ = 0 ⇒ Ф = 0.0°

- If 3 sinФ - 2 = 0 ⇒ 3 sinФ = 2 ⇒ sin Ф = 2/3

∵ sinФ 2/3

∴ Ф = 41.8° ⇒ Ф ≤ 90° (in first quadrant)

∵ -90° ≤ Ф ≤ 90°

∴ Ф = -41.8° ⇒ Ф ≥ -90° (in fourth quadrant)

∴ The solutions of the equation are -41.8° , 0.0° , 41.8°

To find the surface area of any prism, you multiply the base by the height.

10 x 5 = 50

Answer: Right (Last option)

Step-by-step explanation:

As you can see in the figure, the parallel lines AD and GJ are intersected  by two lines.

The line EL intersects the parallel lines and there are two angles that are formed by this intersections which are located on the exterior of AD and GJ, but  on opposite sides of EL, (these angles are called "Alternate exterior angles" and they are congruent), which are:

 ∠LHJ and ∠EBA

You can observe that the angle ∠EBA is indicated with a square. This means that the measure of that angle is 90° (Right angle).

Therefore, if ∠EBA=90°, then ∠LHJ =90°

Answer:

The correct answer is last option Right

Step-by-step explanation:

From the figure we can see that,

AD ║ GJ and LE is the traversal.

And also given <ABE = 90°

Fro figure we get <ABE and <GHB are corresponding angles. Corresponding angles are equal.

Therefore <GHB = 90°

To find the <LHJ

From figure we can see that <LHJ and <GHB are vertically opposite angles.

Vertically opposite angles are  equal.

Therefore <LHJ = <GHB = 90°
