Answer: To make 7 servings of the recipe, you will need:

Sauce: 7 servings * 15 cups/5 servings = <<7*15/5=21>>21 cups

Oregano: 7 servings * (2.5 tsp/5 servings) = <<7*(2.5/5)=1.75>>1.75 tsp

So, you will need 21 cups of sauce and 1.75 tsp of oregano to make 7 servings of the recipe.

Step-by-step explanation:

They will need 21 cups of sauce and 1.75 tsp of oregano to make 7 servings of the recipe.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Now, To make 7 servings of the recipe, you will need:

Sauce:

⇒ 7 × 15 /5

⇒ 21 cups

Oregano: \

⇒ 7 × (2.5 /5 )

⇒ 1.75 tsp

So, you will need 21 cups of sauce and 1.75 tsp of oregano to make 7 servings of the recipe.

Answer:

To solve the equation |2x - 5| = 7, you can set up two equations, one for the positive solution and one for the negative solution.

For the positive solution, you can start by isolating the absolute value expression on the left-hand side of the equation: |2x - 5| = 7 can be rewritten as 2x - 5 = 7. Then, you can solve this equation by adding 5 to both sides to get 2x = 12, and then dividing both sides by 2 to get x = 6.

For the negative solution, you can start by noting that the absolute value of a number is equal to its opposite if it is negative, so |2x - 5| = 7 can be rewritten as -(2x - 5) = 7. This equation can be solved by multiplying both sides by -1 to get 2x - 5 = -7, and then adding 5 to both sides to get 2x = -2. Then, dividing both sides by 2 to get x = -1.

Therefore, the two equations to solve the equation |2x - 5| = 7 are 2x - 5 = 7 and 2x - 5 = -7.

Answer:

C

Step-by-step explanation:

To solve the equation |2x - 5| = 7, we need to set up two equations, one for the case where the absolute value is equal to the positive value of the expression inside the absolute value bars, and one for the case where the absolute value is equal to the negative value of the expression inside the absolute value bars.

The first equation we need to set up is 2x - 5 = 7. In this case, the absolute value is equal to the positive value of 2x - 5, so we can simply set the expression inside the absolute value bars equal to the given value of 7. This equation can be written as follows:

2x - 5 = 7

The second equation we need to set up is -(2x - 5) = 7. In this case, the absolute value is equal to the negative value of 2x - 5, so we need to set the negative of the expression inside the absolute value bars equal to the given value of 7. This equation can be written as follows:

-2x+5 = 7

We can use these two equations to solve for the value of x. To solve the first equation, we can simply add 5 to both sides to get 2x = 12, and then divide both sides by 2 to get x = 6. To solve the second equation, we can first distribute the negative sign to get -2x + 5 = 7, and then add 5 to both sides to get -2x = 2. Finally, we can divide both sides by -2 to get x = -1.

Therefore, the two solutions to the equation |2x - 5| = 7 are x = 6 and x = -1.

Alternative:

2x-5 = 7

2x-5 = -7

Answer:

f(-4)=16

Step-by-step explanation:

since f(x)=8-2x and we are asked to find f(-4),

we plug -4 in for x and we get

[tex]f(-4)=8-2(-4)[/tex]

[tex]2*-4=-8[/tex]

[tex]8-(-8)=8+8[/tex]

[tex]8+8=16[/tex]

[tex]f(-4)=16[/tex]

We have to make sure that we are taking square roots of non-negative values to stay within the real number system.

You have to make sure x^2-16 ≥ 0 for the inner square root to stay in the real numbers.

You also have to make sure sqrt(x^2-16)-3 ≥ 0 for the outer square root to stay in the real numbers.

Solving x^2-16 ≥ 0 we have that x^2 ≥ 16, so either x≥4 or x≤-4.

Solving sqrt(x^2-16)-3 ≥ 0, we have

     sqrt(x^2-16) ≥ 3

              x^2-16 ≥ 9

                   x^2 ≥ 25

    either x ≥ 5 or x ≤ -5.

Since that second condition is more restrictive that x ≥ 4 or x ≤ -4, we can default to just using

   { x | x ≥ 5 or x ≤ -5 }

   (-infty, -5) U (5, infty)

The solution set of the compound inequality is written as:

(-∞, -4] U (6,  ∞)

First, we need to simplify the two given inequalities, the first one is:

7x + 6 > 4x + 24

Grouping like terms we will get:

7x - 4x > 24 - 6

3x > 18

x > 18/3

x > 6

The other inequality gives:

2*(-13x - 1) - 8 ≥ -10x + 54

-26x - 2 - 8 ≥ -10x + 54

-26x - 10  ≥ -10x + 54

-10 - 54 ≥ -10x + 26x

-64 ≥ 16x

-64/16 ≥ x

-4 ≥ x

So the compound inequality is:

-4 ≥ x

x > 6

Answer:

Infinite number of integers that satisfy the inequality |x|<4.

Step-by-step explanation:

The absolute value of a number indicates its distance from 0 on the number line. Therefore, the inequality |x|<4 indicates that x is less than 4 units away from 0 on the number line. Because there are an infinite number of integers on the number line, there are an infinite number of integers that satisfy the inequality |x|<4.

The statement that best reflects the grade is "The variances of anxiety scores were roughly the same in the different groups of musicians."

The term variances refers the mean squared difference between each data point and the center of the distribution measured by the mean

Here we have given that a music teacher had noticed that some students went to pieces during exams and he wanted to test whether this performance anxiety was different for people playing different instruments. While he took groups of guitarists. drummers and pianists (variable = 'Instru') and measured their anxiety (variable = 'Anxiety') during the exam. Here he also noted the type of exam they were performing (in the UK, musical instrument exams are known as 'grades' and range from 1 to 8 ).

Now, we need to find the statements best reflects what the effect of GRADE in the table tells us.

While we looking into he given question we have identified that this performance anxiety was different for people playing different instruments.

So, based on this concept the correct statement id option (c).

On analyzing the data given in question we get to know that the sensitivity is negative.

Our function is 40 + 24 x 2.4 /1 + 4x  to the point.

For the time being, our first task is to determine the sensitivity, which is the derivative of our discovery. The quotient rule, whose derivative we shall be utilizing, says that the derivative of F org equals G f prime minus f g prime all over g squared.

The bottom function is one plus four times the top function's derivative, or 40.4 times. 40 has a derivative of zero.

When a light source is x cm away from a light probe, the light's intensity is measured as y microwatts per square cm. The outcomes are displayed as ordered pairs( x , y).

So we just need to multiply 24 x240.4.

Using the power rule, we can reduce the 0.4 point to 9.6 x to the minus 0.6.

We subtract one from the initial exponents minus the top function 40 + 24 x to the point for times the bottom function's derivative 10 So we have the derivative of four additional 40.4 by the power rule,

we bring down the 0.4 multiplied by four against 1.6 next to the minus 0.6, and we divide all of that by one plus four x to the 40.4 squared.

There is sufficient warrant to rejection of the claim that 64% of the readers of the publisher own a personal computer at a = 0.01 level of significance.

What is the null hypothesis?

Two alternatives being the same is the null hypothesis. The underlying assumption is that the observed difference is just the result of chance. It is feasible to determine the probability that the null hypothesis is correct using statistical testing.

Here, we have

P = population proportion of readers, who own personal computers.

The claim of the publisher: 64% of their readers own a personal computer.

Since the claim indicates a specific value about P, it should be treated as the null hypothesis and thus the required null and alternative hypothesis would be -

H₀ : p = 0.64

H₁  : p ≠ 0.64

Now, at a = 0.01, it is decided to reject the null hypothesis.

The continuous function f is defined on the closed interval −6 ≤ x ≤ 5. The figure above shows a portion of the graph of f, consisting of two line segments and a quarter of a circle centered at the point (5, 3). It is known that the point (3, 3 −√5 ) is on the graph of f. 4.

In mathematics, a continuous function is a function such that a continuous variation (that is a change without jump) of the argument induces a continuous variation of the value of the function. This means that there are no abrupt changes in value, known as discontinuities. More precisely, a function is continuous if arbitrarily small changes in its value can be assured by restricting to sufficiently small changes of its argument. A discontinuous function is a function that is not continuous. Up until the 19th century, mathematicians largely relied on intuitive notions of continuity, and considered only continuous functions. The epsilon–delta definition of a limit was introduced to formalize the definition of continuity.
