Jorge is making 6 large salads and 4 small salads how many cherry tomatoes does he need.

Answer:

0.25

Step-by-step explanation:

Probability is the chance you get a certain thing when you pick randomly. In this case, it's asking the probablility of picking someone from a whole student survey that does music or drama.

Looking at the two way table is easy! Out of all grades, 65 are in sports, 25 have music or drama, and 10 has work. Add them all up and get 100.

However, we only found the people in the survey. We need to find the probability of someone in music and drama. So we divide the number of people in all grades who take that class and divide it by the total amount- 25/100, this turns out for the probability to be 0.25.

I'm always happy to help :)

The probability should be [tex]1\div 36[/tex].

Since You roll a fair six-sided die twice. The first roll shows a five and the second roll shows a six.

So here the probability should be

Answer:

[tex]\frac{8 cupcakes}{1 box}[/tex]

Step-by-step explanation:

All we have to do for this problem is divide.

48 / 6 = 8

There are 8 cupcakes per box.

Answer: 8 cupcakes per box

Step-by-step explanation: "Per box" means in 1 box, so we can rewrite the given statement using fractions as

48 cupcakes/6 boxes = __ cupcakes/1 box.

To find out what goes in the blank, notice that we

have a 1 in the denominator of our second fraction.

So we want to find a fraction that is equivalent

to 48/6 that has a 1 in the denominator.

If we divide the numerator and denominator of 48/6 by 6,

we get the equivalent fraction 8/1 or 8 cupcakes/1 box.

So now we have 8 cupcakes/1 box = __cupcakes/1 box.

So an 8 must go in the blank which means that the unit rate

for 48 cupcakes in 6 boxes is 8 cupcakes per box.

Answer:

3/2 Per wall

Step-by-step explanation:

There are four walls in a room.

6/4 = 3/2

To check your work, you can do 3/2 *4

3/2*4 = 6

Hope this helps!! :)

The number of rolls that each wall requires is 1.5.

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.

Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

Given:

There are four walls in a room.

He is able to cover of the walls in the room using 6 rolls of wallpaper.

let x as the number of rolls that each wall requires.

So, 4x =6 rolls

x=6/4

[tex]\large \boxed{(-1,-6),(-1,10)}[/tex]

Step-by-step explanation:

Point A must be on a circle with centre at (5,2) and radius 10.

The centre-radius form for the  equation of a circle is  

(x – h)² + (y – k)² = r², where

(h,k) = the coordinates of the centre and

     r = the radius

Thus, the equation for this circle is

(x - 5)² + ( y - 2)² = 10²

Substitute the value for x and solve for  y:

[tex]\begin{array}{rcl}\\(x - 5)^{2} +( y - 2)^{2} &=& 10^{2}\\(-1 - 5)^{2} +( y - 2)^{2} &=& 100\\(-6)^{2} +( y - 2)^{2} &=& 100\\36 +( y - 2)^{2} &=& 100\\( y - 2)^{2} &=& 64\\y - 2 = -8 & \qquad & y - 2 = 8\\y = \mathbf{-6} & \qquad & y = \mathbf{10}\\\end{array}\\\text{The possible coordinates of A are $\large \boxed{\mathbf{(-1,-6),(-1,10)}}$}[/tex]

Answer:

C.I = 0.108 ± 0.022

Step-by-step explanation:

In this case, we are given a symmetric confidence interval, and the sample proportion p', is derived by finding the average of the two values.

Therefore, the sample proportion will be:

[tex] p' = \frac{0.086 + 0.130}{2} [/tex]

[tex] = \frac{0.216}{2} [/tex]

= 0.108

p' = 0.108

To find the margin of error, we have:

M.E = ½ * length of confidence interval

Where length of confidence interval = 0.130 - 0.086

= 0.044

Therefore,

[tex] M.E = \frac{1}{2} * 0.044 = 0.022 [/tex]

Margin of error = 0.022

The confidence interval is expressed as:

p' ± M.E

= 0.108 ± 0.022

Answer: 1/125,000

Step-by-step explanation:

If the lenght of the building is L, the height is H, and the width is W, the volume of the building is V = L*H*W

Then for the model we will have that each measure is 1/50 times the original, this is:

lenght = L/50

height = H/50

widht= W/50

The volume of the scale model is:

V' = (L/50)*(H/50)*(W/50) = L*H*W/50^3

So we have the volume of the actual building divided 50^3

This means that the volume of the scale is 1/50^3 = 1/125,000 times the volume of the actual building.

Circle Equation: ( x - 3.8 )^2 + ( y - 7.8 )^2 = 25/36

Step-by-step explanation:

* Knowing a circle equation is in the format (x – h)^2 + (y – k)^2 = r^2, with the center being at the point (h, k) and the radius being "r" *

Let us substitute values into this equation; provided ( 3.8, 7.8 ) is the center:

( x - 3.8 )^2 + ( y - 7.8 )^2 = r^2,

Now substitute value of r, or rather the radius 5/6:

( x - 3.8 )^2 + ( y - 7.8 )^2 = ( 5/6 )^2 ⇒

Circle Equation: ( x - 3.8 )^2 + ( y - 7.8 )^2 = 25/36

Do you have a question to ask ?

Answer:

The answer is -3.1, or 3 1/10.Since diving a negative and a positive equals a negative, your quotient will be negative. You can start by removing the 0.5, and divide 15 by 5 which is 3. Then with the 0.5 from -15.5, divide it by 5 and you get 0.1. 3 plus 0.1 is 3.1, and since it has to be negative, it's -3.1.

Answer:

13 packages

Step-by-step explanation:

We need to first find the area of the composite figure. We can draw a horizontal line through the figure so that it is broken up into two rectangles.

The top rectangle has dimensions of 9 ft by 2 ft, while the bottom rectangle has dimensions of 3 ft by 7 ft. The area of a rectangle is denoted by: A = lw, where l is the length and w is the width.

Here, the top rectangle has width 9 and length 2, so the area is A = 9 * 2 = 18 square feet. The bottom rectangle has width 7 and length 3, so the area is A = 7 * 3 = 21 square feet. Add these up:

18 + 21 = 39 square feet

We know that each package of tile will cover 3 square feet, so divide 39 by 3 to get the number of packages needed:

39 / 3 = 13

The answer is 13 packages.
