The letters in the word JANUARY were put in a bag and drawn randomly. What is the probability of picking an a?
Answer: 2/7
Step-by-step explanation:
There are 7 letters in January, and 2 "a"s in order to find the probability, simply take 2/7. You can either leave it in the fraction form, or use the calculator, showing you have a 0.2857% chance of picking an "a"
2/7
there are 7 letters in jAnuAry and as you can see there are 2 A's so there is a 2/7 chance which is higher of a chance than the rest of the letters which are 1/7 each so it is most likely you would draw A although I can't fully say that because there is a 5/7 chance of drawing the other letters. Another way to say it is there is a 0.28571428571% chance of drawing A but there is a 0.71428571428% chance of drawing any other letter.
Hope this helps :3

Alex rents a car for one day the charge is $28 plus $0.50 per mile Alex wants to spend exactly $30 how many miles can he drive
Answer:
4 milesStep-by-step explanation:
Let the miles is x:
28 + 0.5x = 300.5x = 30 - 280.5x = 2x = 2/0.5x = 4It seems incorrect but Alex can drive 4 miles
AKS 19 -- Dan is driving with an average speed of s. He is driving a total distance of d. What formula represents the total time of his trip? Question 2 options: t=ds t = d s t=ds t=d-s t=sd
Answer:
[tex]t=\dfrac{d}{s}[/tex]
Step-by-step explanation:
Dan is driving with an average speed of s. He is driving a total distance of d.
The average speed of an object is given by :
Average speed = total distance/total time
Let b the time of his trip
So,
[tex]s=\dfrac{d}{t}\\\\or\\\\t=\dfrac{d}{s}[/tex]
So, the formula for the total time of his trip is [tex]\dfrac{d}{s}[/tex].
Jim gives the cashier a $20 bill at the pharmacy.
Write an equation that relates the change c he gets back in dollars to the cost b, in dollars, of his purchases. Which variable represents the independent variable? How much change does he get back if his purchases total $12.83?
Answer:
b= 12.83
c= 7.17
Variable "c" is independent because it does not change. Jim receives $7.17 back.

Answer:
We have the value as;
8x/5
Step-by-step explanation:
Here, we want to get the breakdown of the given expression
We have (x^2 - 9) as (x-3)(x + 3)
So we have;
2x/(x + 3) * (x-3)(x+3)/5 * 4/(x-3)
= 2x * 4/5= 8x/5
Given the function h(x)=-x^2+4x+12, determine the average rate of change of the function over the interval −2≤x≤4.
Answer:
2
Step-by-step explanation:
The average rate of change of h(x) in the closed interval [ a, b ] is
[tex]\frac{f(b) - f(a)}{b-a}[/tex]
Here [ a, b ] = [ - 2, 4 ] , then
f(b) = f(4) = - (4)² + 4(4) + 12 = - 16 + 16 + 12 = 12
f(a) = f(- 2) = - (- 2)² + 4(- 2) + 12 = - 4 - 8 + 12 = 0
Then
average rate of change = [tex]\frac{12-0}{4-(-2)}[/tex] = [tex]\frac{12}{6}[/tex] = 2

The center of a circle is (0, -8). The radius is 9. What is the equation of the circle? Select all that apply.
A. x2 + (y + 8)2 = 3
B. x2 + (y + 8)2 = 9
C. x2 + (y + 8)2 = 81
D. x2 + y2 + 16y = 17
E. x2 + y2 + 16y = -55
Answer:
x² + (y + 8)² = 81
Step-by-step explanation:
Centre (h,k) = (0,-8)
radius (r) = 9
(x - h)² + (y - k)² = r²
(x - 0)² + (y + 8)² = 9²
x² + (y + 8)² = 81
2a + 3c = 5
a +2c=1
There is an ordered pair that is the solution of the system of equations shown. The value of one of the variables in the solution of the system can be obtained by using which of the following substitutions?
A) 2 (2c - 1) + 3c = 5, because a = 2c - 1.
B) 2 (1 - 2c) + 3c = 5, because a = 1 - 2c.
C) 2a + 3 (a - 1) = 5, because c = a - 1.
D) 2a +3(1 - a) = 5, because c = 1-a
Answer:
A
Step-by-step explanation:
The required system that can be obtained by substituting is
2 (1 - 2c) + 3c = 5, because a = 1 - 2c.
Given the system of equation;
2a + 3c = 5
a +2c=1
This system can be solved using the substitution method.
From equation 2:
a = 1 - 2c ...................... 3Substitute equation 3 into 1 will give:
2a + 3c = 52 (1- 2c) + 3c = 5Hence the required system that can be obtained by substituting is
2 (1 - 2c) + 3c = 5, because a = 1 - 2c.

10 points PLEASE HELP
Answer:
170
Step-by-step explanation:
If you look at the other angle it says 20 and a whole circle would be 360 so subtract 360-130 then after that since the angle takes 2 part or however you may say that means u subtract 60 (20+20+20 thee open angle) this means you get 170 (i think im unsure but you can try)

PLZ HELP To multiply (7x+3)(7x−3),
you can use the pattern:
(a+b)(a−b)=a2−b2.
What are the values of a and b?
Enter your answers in the boxes below.

Answers:
a = 7xb = 3==========================================================
Explanation:
Match up (7x+3)(7x-3) with (a+b)(a-b)
We have
(7x+3) pair up with (a+b)(7x-3) pair up with (a-b)We can see that a = 7x and b = 3
Furthermore, we can say,
(a+b)(a-b) = a^2 - b^2
(7x+3)(7x-3) = (7x)^2 - (3)^2
(7x+3)(7x-3) = 49x^2 - 9
The values of a and b are 7x and 3 respectively
(7x+3) (7x−3)
Using the format
Factorisation(a + b)(a − b) = a² − b²
Therefore,
a = 7x
b = 3
Therefore,
From (a + b)(a − b) = a² − b²
(7x+3) (7x−3) = (7x)² - 3²
(7x+3) (7x−3) = 49x² - 9
