Answer:
9/40= 0.225 (experimental probability for white)
(b) because the spinner has 10 sections but there has only been 3 outcomes. If the spinner has 3 sections the changes of white would be 0.333.
2. Is correct, the more times you spin the closer you’ll get to the theoretical probability.
Step-by-step explanation:

A tank that is 40% full contains 650 gallons of water. On a side sheet of paper, use a double number line to find the maximum capacity of the water tank.
What did you get?
gallons
Answer: max capacity is 1625 gallons.
Diagram is shown below.
=========================================================
Explanation:
We'll draw two horizontal number lines to help make a comparison or connection between percentages and tank capacity.
For the top number line, make 5 sections with the labels: 0%, 20%, 40%, 60%, 100%. The reason I'm picking 5 is because 40% = 40/100 = 2/5. So having 40% capacity means we're 2/5 full. That denominator 5 tells us how to subdivide each number line.
The bottom number line will also have 5 sections. We only know one label for this bottom portion right now. That label is 650. Place this directly under the "40%". This visually is one way to represent that 650 gallons is 40% filled. See the diagram below.
Cut the 650 in half to get 325. This corresponds to 40% cut in half to get 20%. Therefore, 325 will go under the 20%. Being 20% full means we have 325 gallons of water.
To figure out the 60% portion, we will multiply 325 by 3. This is because 3*20% = 60%, so 3*325 = 975. We'll write "975 gallons" under the "60%"
Then we have 1300 gallons under the 80% since 4*325 = 1300. Note how 4*20% = 80%, so that's where the '4' multiplier comes from.
Finally, we multiply 325 by 5 to get 1625 and that represents the full tank's capacity. Technically we could have just jumped to this directly without having to find the 60% or 80% capacity values, but it's good practice I think.
Again the diagram is shown below. The answer we're after is at the very bottom right corner. It's under the 100% to indicate the tank is completely full, or has reached max capacity.
-----------------------
Here's a way to find the answer without a double number line. This method involves setting up a proportion.
(40% full)/(650 gallons) = (100% full)/(x gallons)
40/650 = 100/x
40x = 650*100
40x = 65000
x = 65000/40
x = 1625
We confirm that the tank's max capacity is 1625 gallons.
You roll a number cube two times in a row. What is the probability of rolling a 3 the first time and an even number the second time?
The probability of rolling a 3 the first time is 1/6.
The probability of rolling an even number is 1/2.

Hector's parents started saving money for his college education when Hector was six. If they save $400 per month at a credit union account, paying 2.5% interest compounded daily, how much will Hector have for college expenses 12 years later?
Answer:
$539.94
Step-by-step explanation:
The formula for calculating future value:
FV = P (1 + r/m)^mn
FV = Future value
P = Present value = $400
R = interest rate = 2.5/ 365
N = number of years = 12 x 365
$400 x ( 1 + 0.025/365)^4380 = $539.94

Twice the difference of a number and 2 is 7.
Answer:
9
Step-by-step explanation:
-Twice means muliply by 2
-The difference of a number and 7 means subtract a number/variable and 7.
-Is equal to 9 means =9
2(X - 7) = 9
An equation to model the number is: n - 7 x 2 = 2
To find the equation, break apart the question.
twice the difference of a number and 7 equals 2. - "Twice" means we are multiplying by 2, or x 2
twice the difference of a number and 7 equals 2. "The difference of a number and 7" means we are subtracting n - 7, and this is being multiplied by 2 so we have n - 7 x 2 so far.
twice the difference of a number and 7 equals 2. "Equals two" means the equation is equal to 2, or = 2, so our equation is n - 7 x 2 = 2.

Complete question :
Jelena has a piece of fabric in the shape of a parallelogram the height is 10 feet and its base is 16 feet because the fabric into four equal parallelograms by current base and the height in half what is the area of each new parallelogram?
Answer:
40 ft²
Step-by-step explanation:
Given that:
Height = 10 feets
Base = 16 feets
Area of parallelogram = height * base
Area of parallelogram = 10 * 16 = 160 ft²
Area of each new parallelogram :
Area of parallelogram / number of divisions
= 160ft² / 4
= 40 ft²

Answer:
x = 11
Step-by-step explanation:
33 divided by 3 is 11, and 11 times 3 is 33.
answer:
11
step-by-step explanation:
the easiest way to explain this is just to divide
33/3
which gets you the answer of 11
but here is another way to explain this
3x = 33
since the 3 and the x are times/multiplying each other and we need to get x by its self, all we do is move the 3 to the other side ( where 33 is ) but instead of multiplying them, we have the change the sign to dividing
3x = 33
/3 ----|>
( dont forgot to rewrite the equation!! )
x = 33/3
now all we need to do is divide 33 by 3 which gives us the answer of
11
hope this helps you! and if you ever need anymore help of problems like theses, just ask me :)

What does the Elimination method look like? what is the strategy?
Answer:
the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.
Which equation is true?
f(x) - 5 = g(x)
f(x) = g(x) - 5
Of(x) = g(x - 5)
Of(x - 5) = g(x)
PLZZZ HELPPP
Answer:
f(x)-5 = g(x)
Step-by-step explanation:
We translate the function g(x) down 5 units from the function f(x)
g(x) = f(x) -5
Rewriting
f(x)-5 = g(x)
Answer:
Option A
Step-by-step explanation:
f(x)-5=g(x)f(x) and g(x) are exponential functions
We can see that f(x) is shifted 5 units down
So change in y
hence 5 is to be subtracted

Find an equation of the line passing through the pair of points (4,5) and (6,9) . Write the equation in the form Ax+By=C .
Answer:
-2x + y = -3
Step-by-step explanation:
Find the slope:
9 - 5 / 6 - 4 = 4/2 = 2
Put it in point-slope form:
y - 5 = 2(x - 4)
rearrange:
y - 5 = 2x - 8
y - 2x = -3
-2x + y = -3

Can someone please help me? thank you.
Answer:
Step-by-step explanation:
c(f) = [tex]\frac{5}{9}(f-32)[/tex]
[tex]-21 = \frac{5}{9}(f-32)[/tex]
Multiply both sides by 9
-21*9 = 5(f - 32)
-189 = 5*f - 5*32
-189 = 5f - 160
Add 160 to both sides
-189 + 160 = 5f
-29 = 5f
Divide both sides by 5
-29/5 = f
f = -5.8
f = -6 °C
Help please and thank you.

Mandy spent $287 on 7 pairs of shoes. She purchased some pairs of boots that cost $65 per pair and some pairs of workout shoes that cost
S23 per pair
Use a system of equations to help you identify how many pairs of boots (b) and workout shoes (w) Mandy bought
Enter the number of pairs of boots and workout shoes Mandy bought
Answer: Boots = 3
workout shoes = 4
Step-by-step explanation:
boots cost $65 so 65 x 3 = 195
and workout shoes cost $23 so 23 + 4 = 92 then 195 + 92 = 287
