Answer:
We have:
4 red panels
5 yellow panels
1 bankrupt panel
7 blue panels
2 free spin panels
for a total of:
4 + 5 +1 + 7 + 2 = 19 panels.
And we can assume that all the panels are equal, so the probability of landing on every single one is the same.
a) Probability of a spin landing on a red panel.
This will be equal to the quotient between the number of red panels (4) and the total number of panels (19)
P = 4/19 = 0.211
b) Probability of a spin landing on anything but a blue panel
There are 7 blue panels and a total of 19 panels.
then 19 - 7 = 12 panels are not blue.
The probability of not landing on a blue panel will be equal to the quotient between the number of panels that are not blue (12) and the total number of panels (19)
P = 12/19 = 0.632
c) Probability of a spin landing on a yellow or red.
There are 4 red and 5 yellow ones, so there are 4 + 5 = 9 panels that are either red or yellow.
The probability is computed in the same way as in the above cases, here we have:
P = 9/19 = 0.473
d) Probability of a spin landing on any non-color panel.
The non-color panels are:
1 bankrupt panel and 2 free spin panels, for a total of 3 non-color panels.
The probability is computed in the same way as above, so we get:
P = 3/19 = 0.158

Answer:
?
Step-by-step explanation:
michelle is 3 times as old as her sister tina. Tina is 4 years younger than michelle. How old is tina now?
Answer:
Tina's age = 2 years
Step-by-step explanation:
Tina's age = x
Michelle's age = 3 * x = 3x
Tina is 4 years younger than Michelle.
x = 3x - 4
Add 4 to both side
x +4 = 3x
Subtract x from both sides
4 = 3x - x
4 = 2x
Divide both sides by 2
4/2 = x
2 = x
Tina's age = 2 years
find f(x)•g(x)
f(x) = 3x - 1
g(x) = x^2 + 4
1. the question is asking you to multiply the two function expressions together
2. so all we do is (3x - 1)(x² + 4) which gives you 3x³ + 12x - x² - 4

What is the area? please help
Answer:
70.875 [tex]km^{2}[/tex]
Step-by-step explanation:
Using the equation of area of trapezium
[tex]\frac{1}{2} * (a+b)h[/tex]
Put the value into the equation
[tex]\frac{1}{2}(4.8+5.7)*13.5[/tex]
Simplify the equation and you will get:
[tex]2.4*13.5=70.875 km^{2}[/tex]
So, the answer is 70.875km^2

Please help I will give you Brainlyest
Answer:
A positive number.
Any negative subtracted from a positive will always be positive.
Answer:
a-b will be and will always be a POSITIVE number.
This is because a is positive, and b is negative.
However, when you subtract a negative number, you are actually just adding it.
So, a - (-b) = a+b.
This is why, it will always be positive.

What is the average rate of change for the function f(x) = –4x2 + 1 over the interval –3/2 ≤ x ≤ 0?
Answer:
6
Step-by-step explanation:
To find the average rate of change, we must calculate the slope over the interval -3/2 to 0. We can use the formula below.
f(b) - f(a) / b - a
f(0) - f(-3/2) / 0 - -3/2
1 - -8 / 3/2
9 / 3/2

The graph of a linear relation passes through the point (-2,7) and has a slope of 1/6.
Determine an equation for this linear relation in slope intercept form.
Answer:
Step-by-step explanation:
eq. of any line withslope 1/6 is
y=1/6x+c
∵ it passes through (-2,7)
so 7=1/6(-2)+c
c=7+1/3=22/3
eq. of line is
y=1/6x+22/3
Answer:
y = 1/6x + 7 1/3
Step-by-step explanation:
Slope intercept form is y=mx+b where m is the slope and b is the y intercept
y = 1/6x+b
Substitute the point into the equation
7 = 1/6(-2)+b
7 = -1/3+b
Add 1/3 to each side
7 1/3 = b
y = 1/6x + 7 1/3

find the length of one side of a regular hexagon if its perimeter is 24 x+48
A. 3x+3
B. 6x+12
C. 4x+8
D. 8x+16
Answer:
C ) 4 x + 8
Step-by-step explanation:
( 24 x + 48 ) / 6
4 x + 48
The length of a regular hexagon is:
4x ₊ 8
How many sides do a hexagon have? How do we calculate the length and parameter of it?
A regular hexagon have six sides.
The area of a regular hexagon can be calculated using the formula (33 s2)/2, where s is the side length. The lengths of all six sides of a hexagon can be added to determine its perimeter. Perimeter = 6 s, where s is the length of one side, is the formula used to determine the size of a regular hexagon.
Solution:
Given,
parameter of a hexagon = 24x ₊ 48
length of one side of a hexagon s = p ÷ 6
s = 24x ₊ 48 ÷6
s = 4x ₊ 8
Hence we get the length of one side as 4x ₊ 8

Evaluate the expression 34 ÷ (14 − 5) × 2.
I'm pretty confused can someone explain it to me? I will give branliest
Answer:
[tex]7\frac{5}{9}[/tex]
Step-by-step explanation:
Hi there!
We are given this expression:
34÷(14-5)×2
And we want to evaluate it
We'll be using the order of operations
Depending on the country you're in, the acronym can be different, but in the US, the typical acronym used for the order of operations is PEMDAS, or Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
The order of operations states that we should start with any expressions in parentheses
In this case, it's (14-5), which is equal to 9
The expression now becomes
34÷9×2
There are no exponents, so let's skip that
Now this is where it gets tricky:
Based on the acronym alone, we should be doing 9*2 next, however, we should always work left to right, even if in a case like this, we'll be doing division instead of multiplication
Divide 34 by 9
[tex]\frac{34}{9}[/tex]×2
Now multiply [tex]\frac{34}{9}[/tex] by 2
[tex]\frac{68}{9}[/tex]
(as a mixed fraction, it's 7[tex]\frac{5}{9}[/tex])
Hope this helps!
