1. Ratio of medals won by Josephine to the total number won by the team: 1/13 (A)

2. Ratio of medals won by Jacob to medals won by Antonio: 2/1 (D)

Ratio can be described as a quantitative relation that compares how many times a value is contained in another.

1. Ratio of medals won by Josephine to the total number won by the team:

Total won by the team = 26

Medals won by Josephine = 2

Ratio = 2:26 = 2/26

= 1/13 (A)

2. Ratio of medals won by Jacob to medals won by Antonio:

Jacob = 8

Antonio = 4

Ratio = 8:4 = 8/4

= 2/1 (D)

Bar chart visualization should be used if there is an association between birth and death rates during a given time interval.

A bar chart is a chart that is used to represent data using rectangular bars with heights proportional to the values that they represent. Bar charts can either be vertically or horizontally.

Bar graphs are usually used when comparing two or more different things as well as their respective changes over time.

Bar chart visualization should be used if there is an association between birth and death rates during a given time interval.

Answer:

[tex]y = 4[/tex]

Step-by-step explanation:

First, find the derivative of f:

[tex]\displaystyle \begin{aligned} f'(x) & = \frac{d}{dx}\left[ 2x^3 - 3x^2 + 5\right] \\ \\ & = 6x^2 - 6x \\ \\ & = 6x(x-1)\end{aligned}[/tex]

Find the instantaneous slope at x = 1:

[tex]\displaystyle \begin{aligned} f'(1) & = 6(1)((1)-1) \\ \\ &= 0 \end{aligned}[/tex]

From the point-slope form, find the equation of the line:
[tex]\displaystyle \begin{aligned}y - y_1 & = m(x-x_1) \\ \\ y - (4) & =(0)(x-(1)) \\ \\ y & = 4 \end{aligned}[/tex]

In conclusion, the equation of the tangent line is y = 4.

Answer:

6.75

Step-by-step explanation:

first let's simplify whatever is inside the parantheses

8(2x-10)=28

8*2(x-5)=28

16(x-5)=28

now we divide both sides by 16 to get rid 16

x-5 = 28/16

now move -5 to the right side

x = 28/16 + 5

x = 28/16 + 80/16 = 108/16 = 6.75

Answer and Step-by-step explanation:

So for this question, we need to create an equation. We will use one of the most common forms of equations of math, which would be the linear equation of y=mx+b. The only difference is, we need to change the = to a ≥ symbol, meaning greater than or equal to, because the 100 dollars needs to be more or equal to the amount spent. But we cannot solve this problem until we know where everything goes.

So, the 100 is all she can spend, so this is where the ≤ comes in handy. She can use less than or equal to the amount of 100 dollars for the food for this party. And because she started out with 19 dollars, that can be added into the problem. So far we have:

100 ≥ __x + 19.

Now we need to find what the missing part of the equation is. But first let's change the x to p in this equation so that it is easier to understand. The p stands for the amount of pizzas purchased. Each pizza costs 7 dollars, so the equation should look like this:

100 ≥ 7p + 19. Now we solve for p.

-19           - 19 Subtract 19 from both sides to cancel out the positive 19 (+ 19).

81 ≥ 7p           Divide 7 into 81 to single out p.

7      7            So p = 81/7. But we can't have 81/7 of a pizza, so we convert this to a decimal then round. So: 11.57142857… is the decimal form.

Now we need to round, because that is way too big. So, we round to the nearest whole number. So we look at the placement behind it (The tenths placement in this situation). Because the placement behind it (5) is on the 5 - 9 scale, the placement before it gets rounded up.

So, Ava can buy 12 pizzas.

I hope that this helps.

[tex]x=\frac{-24-5(-4)}{2}[/tex]

[tex]x=-2, y=-4[/tex]

Answer:

[tex]{x,y} = {-2,-4}[/tex]

Step-by-step explanation:

[tex]2x + 5y = -24 \\ 2x + y = -8[/tex] <---------- Linear equations given

Graphic Representation of the Equations : PICTURE

[tex]5y + 2x = -24 \\ y + 2x = -8[/tex]

Solve by Substitution :

// Solve equation [2] for the variable  y

[tex][2] y = -2x - 8[/tex]

// Plug this in for variable  y  in equation [1]

[tex][1] 2x + 5*(-2x-8) = -24\\ [1] -8x = 16[/tex]

/ Solve equation [1] for the variable  x

[tex][1] 8x = - 16 [1] x = - 2[/tex]

// By now we know this much :

[tex]x = -2 \\ y = -2x-8[/tex]

// Use the  x  value to solve for  y

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

Solution :

[tex]{x,y} = {-2,-4}[/tex]

Answer:
