### Learn more about Ratios here:

There are 420 students divided into 7 parts due to the ratio of girls to boys being 4:3. With one part totaling 60 students, there are 240 girls and 180 boys. Thus, there are** 60 **more girls than boys.

To solve this problem, you need to understand the concept of ratios. In this case, the ratio of girls to boys is 4:3. This means that for every 4 girls, there are 3 boys. If we add the two parts of the ratio together, we get 7 parts. This means that the total number of students, which is **420**, is to be divided into 7 parts.

So, one part of this ratio is equal to 420 divided by 7, which equals 60 students. Since the ratio claims there are 4 parts of girls and 3 parts of boys, to find out the numbers of girls and boys, we multiply each part of the ratio by 60. Hence, the total number of **girls** is 4 multiplied by 60, which equals 240 and the number of boys is 3 multiplied by 60, which equals 180.

Therefore, the difference in number between girls and boys is 240 minus 180, which equals 60. So there are 60 more girls than boys.

A pharmaceutical manufacturer is concerned that the impurity concentration in pills should not exceed 3%. It is known that from a particular production run impurity concentrations follow a normal distribution with a standard deviation of 0.4%. A random sample of 64 pills from a production run was checked, and the sample mean impurity concentration was found to be 3.07%. Testing at the 5% level the null hypothesis that the population mean impurity concentration is 3% against the alternative that it is more than 3%.a. Calculate the p-value for this test.b. Find the p-value for this test and draw your conclusion.c. Suppose that the alternative hypothesis in part b had been two-sided rather than one-sided. Conduct your test using either the critical value or the p-value approach.

It is believed that the average amount of money spent per U.S. household per week on food is about $98, with standard deviation $11. A random sample of 36 households in a certain affluent community yields a mean weekly food budget of $100. We want to test the hypothesis that the mean weekly food budget for all households in this community is higher than the national average. State the null and alternative hypotheses for this test, the test statistic and determine if the results significant at the 5% level.

Considering it's y-intercept and vertex, the **equation **of the **parabola **is given by:

The equation of a quadratic function, of **vertex (h,k)**, is given by:

In which **a **is the leading coefficient.

In this problem, the vertex is **(1,0),** hence **h = 1, k = 0** and:

The** y-intercept is of 1**, hence, when x = 0, y = 1, so:

Hence, the **equation **is:

More can be learned about the **equation **of a **parabola **at brainly.com/question/24737967

**Answer:**

A

**Step-by-step explanation:**

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (1, 0) , thus

y = a(x - 1)² + 0

To find a substitute the coordinates of the y- intercept (0, 1) into the equation

1 = a(- 1)² = a , thus

a = 1

y = (x - 1)² → A

B) 1 ≤ ƒ(x) ≤ 6

C) –2 ≤ x ≤ 2

D) –2 ≤ ƒ(x) ≤ 2

**Answer:**

**Option (C)**

**Step-by-step explanation:**

Domain of a function is represented by the 'x' values on the graph.

Similarly, y-values of a function represents the range.

Therefore, options (B) and (D) will not be the answer as they are representing the function values or y-values.

Given segments starts form x = -2 and ends at x = 2 (Including these points).

Therefore, Domain of the segment will be [-2, 2] Or -2 ≤ x ≤2

**Option (C) will be the correct option.**

**Answer:**

B) 1 ≤ ƒ(x) ≤ 6

**Answer:**

x = -26

**Step-by-step explanation:**

x/2 + 5 = -8

First let's combine like terms.

Subtract 5 from both sides.

x/2 = -13

Multiply both sides by 2 to isolate x.

x = -26

Plug this back into the original equation to check your answer.

-26/2 + 5 = -8

-13 + 5 = -8

-8 = -8

Your answer is correct.

Hope this helps!

**Answer:**

x=-26

**Step-by-step explanation:**

x/2 + 5 = -8

x/2 + 5 - 5 = -8 - 5

x/2 = -13

x = -26

this is all of the work I did to solve what x is! I hope it helped! There are many other way to solve this problem. This is the way which a lot of ppl do.
