Answer:

1:3

Step-by-step explanation:

circles:total

2:4+2

=2:6

=1:3

Reason

There are 2 circles and 4+2 = 6 shapes total.

The ratio of circles to total shapes is 2:6 which reduces to 1:3

The order is important since 3:1 is different from 1:3.

The total number of lefties present in the class are 125.

For the given question;

The total students in the class are 50.

There are 10 out of 50 on an average students be left-handed.

Let the percentage of left handed be 'x'.

Then, x% of 50 = 10

x = 10×100 / 50

x = 20%.

Now the average number of left-handed students are 25.

The total students will be.

Let 'y' be the total number of students.

Then, 25 is the 20% of y.

20% of y = 25.

y = 25 ×100 / 20

y = 125

Thus, the total number of lefties present in the class are 125.

The mathematical question that can be asked in a situation when Dina goes to a carnival and some rides have a height requirement is how many extra centimeters of height Diana has? The information required to solve this question is the required height for the ride and the height of Diana.

According to the question,

We need to ask a mathematical question. Let's solve a mathematical question in the given situation by taking one example.

If the required height to ride is 150 cm and the height of Diana is 165 cm, how many extra centimeters of height Diana has than the required height?

Solution:

Required height = 150 cm

Dian's height = 165 cm

Extra height = Diana's height - required height of the ride

Extra height = 165 cm - 150 cm

Extra height = 15 cm

Hence, in this supposed situation, Diana's height is 15 cm extra than the required height of the ride.

An equation of the parabola that has the same shape as the graph of f(x) = 4x², but with the point (10,4) as the vertex is y = 4x² - 80x + 404.

             y = a(x - h)² + k  where (h, k) is the vertex.

Given:

f(x) = 4x²

Vertex =  (10,4)

a = 4

The value of a in the vertex form of the equation is taken to be 4 since the coefficients of x² must match for the parabola to have the same shape as the given parabola.

The equation can be written as,

y = a(x - h)² + k  where (h, k) is the vertex.

Replacing the value of the vertex, we get

y = 4(x - 10)² + 4

y = 4(x² - 20x + 100) + 4

y = 4x² - 80x + 400 + 4

y = 4x² - 80x + 404

The probability that, in a random sample of 50 customers at Anita's, exactly 3 order their food to go is 0.3240

Probability:

The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes.

The value of the probability of an event to happen can lie between 0 and 1 because the favorable number of outcomes can never cross the total number of outcomes.

Given,

Anita's, a fast-food chain specializing in hot dogs and garlic fries, keeps track of the proportion of its customers who decide to eat in the restaurant (as opposed to ordering the food "to go"), so it can make decisions regarding the possible construction of in-store play areas, the attendance of its mascot Sammy at the franchise locations, and so on. Anita reports that 48% of its customers order their food to go.

Consider that the slope-intercept of a line is given by,

Here, 'm' is the slope and 'c' is the y-intercept of the line.

The equation of the given line is,

Comparing the coefficients, it can be observed that the slope of the given line is -2,

It is asked to determine the equation of line perpendicular line to this given line.

Let the slope of this perpendicular line be 'k'. Then, the equation of this perpendicular line will take the form,

Theorem: The product of slopes of perpendicular lines is -1.

Now, the equation becomes,

Consider that any point lying on the line must satisfy the equation of that line.

So the point (6,2) must also satisfy the equation of the perpendicular line,

Substitute the values of 'k' and c' in the equation,

Thus, the required equation of the line is obtained as,

The last digits of multiplying 5s and 2s with at least one of each will be zero (0)

From the question, we are to determine what the last digit of the product could be

From the given information,

We are multiplying as many 5s and 2s as we want but we must have at least one of each

Since we must have at least one of each of 5 and 2, we will always have a 5 × 2

But, 5 × 2 = 10

NOTE: 10 multiplied by any number will always result in a number with a last digit of zero (0)

Example

2 × 5 × 2 × 2 × 2 × 2 = 160

5 × 2 × 5 × 5 × 5 × 5 = 6250

The equation of the parabola having focus (1,1) and directix y = -1 is

y = x²/4 - x/2 + 1/4

The focus of the parabola (h , k + p) = (1,1)

The directrix of the parabola is y = -1

From, the focus

           k + p = 1

           k = 1 - p

The formula of directrix is

              y = k - p                                                    (1)

Substituting the value of directrix and k

              -1 = 1 -p -p

              -1-1 = -2p

               -2 = -2p

               p = 1

Substituting the value p in equation (1)

                k = 0

Now, we have got the vertex of the parabola (h ,k) is (1,0)

The equation of the parabola is

    (x-h)² = 4p (y - k)

     (x - 1)² = 4 (1) (y - 0)

Create a ratio of pounds of beef to cups of broccoli, where x is the number of cups of broccoli to one pound of beef:

[tex]\implies \dfrac{3}{4}: \dfrac{9}{8}=1:x[/tex]

[tex]\implies \dfrac{\frac{3}{4}}{\frac{9}{8}}=\dfrac{1}{x}[/tex]

Cross multiply:

[tex]\implies x=\dfrac{9}{8} \div \dfrac{3}{4}[/tex]

To divide fractions, flip the second fraction (make the numerator the denominator, and the denominator the numerator) then multiply it by the first fraction:

[tex]\implies x=\dfrac{9}{8} \times \dfrac{4}{3}[/tex]

[tex]\implies x=\dfrac{9 \times 4}{8 \times 3}[/tex]

[tex]\implies x=\dfrac{36}{24}[/tex]

The slope of the linear equation that passes through the points (9,1) and (10,−1) is -2.

For a linear equation that goes through two points (x₁, y₁) and (x₂, y₂), the slope is given by the formula:

slope = (y₂ - y₁)/(x₂ - x₁)

In this case, we know that our line goes through the points (9,1) and (10, −1), so we can use these two values in the equation for the line, we will get:

slope = (-1 - 1)/(10 - 9) = -2/1 = -2
