A license plate is to consist of 4 digits followed by 2 uppercase letters. determine the number of different license plates possible if the first and second digits must be odd, and repetition is not permitted.
There are [tex]728000[/tex] possibilities of different licence plates.
The License plate is consist of [tex]4[/tex] digits followed by [tex]2[/tex] uppercase letters, i,e,
We have [tex]6[/tex] digits so let's first check the choices of letter or digits over that.
Consider [tex]1[/tex]st Digit , according so question it should be odd so the choices we have for [tex]1[/tex]st Digits are [tex]1,3,5,7,9[/tex] i.e, [tex]5[/tex] choices we have as repitition not allowed.
Now consider [tex]2[/tex]nd Digit , according so question it should be odd so the choices we have for [tex]2[/tex]nd Digits are [tex]4[/tex] because [tex]1[/tex] odd digits has been used in [tex]1[/tex]st Digit.
[tex]3rd[/tex] digit - [tex]2[/tex] digits has been used in [tex]1[/tex]st and [tex]2[/tex]nd digits so [tex]8[/tex] choices left.
[tex]4th[/tex] digit - This is left with [tex]7[/tex] choices.
[tex]5th[/tex]- On this [tex]2[/tex] uppercase letters required so choices we have are [tex]26[/tex].
[tex]6th[/tex]- On this we have to use uppercase so [tex]25[/tex] choices are left as repitition not allowed.
So Possibility of different license [tex]5 \times 4\times\times 8\times 7\times26\times 25=728000[/tex]

A study shows that, over the course of a lifetime, the average salary of college graduates is greater than the average salary of people with only a high school diploma. The results were published claiming that graduating from college ensures you will make more money over the course of your lifetime. What is the problem with reporting results this way?

Correlation and causality
Answer:
Step-by-step explanation:
Given that a study shows that, over the course of a lifetime, the average salary of college graduates is greater than the average salary of people with only a high school diploma.
The results were published claiming that graduating from college ensures you will make more money over the course of your lifetime.
Only means should not be compared. variances of each sample should be ascertained and test for comparison of two means to be done to conclude that one mean is greater than the other.
Hence here problem is correlation and causality.

(–3, 3, –2)
(–6, –4, 5)
(6, 1, –3)
(6, 1, 2)
The point which satisfy the equation 2x + 7y + 3z = -25 will be (–6, –4, 5). The correct option is C.
What is an equation of plane?The equation of the plane is defined as the plane has three variables. Having the coordinates in all three dimensions. The general form of the equation of the plane is ax + by + cz = d.
The given equation of plane is 2x + 7y + 3z = -25.
Check the point which satisfies the equation of the plane. Take the point ( -6,-4,5).
2x + 7y + 3z = -25.
2 ( -6 ) + 7(-4) + 3(5) = -25
-12 - 28 + 15 = -25
-40 + 15 = -25
-25 = -25
Therefore, the point which satisfy the equation 2x + 7y + 3z = -25 will be (–6, –4, 5). The correct option is C.

Suppose an investment of $2,300 doubles in value every decade. The function gives the value of the investment after x decades. f(x)=2300*2^x How much is the investment worth after 2 decades?
(1 point)$2,355,200
$92,000
$46,000
$9,200
The investment is worth $9,200 after 2 decades.
Explanation:To find the value of the investment after 2 decades, we can substitute x = 2 into the function f(x) = 2300 * 2^x.
So, f(2) = 2300 * 2^2 = 2300 * 4 = 9200.
Therefore, the investment is worth $9,200 after 2 decades.

Overdraft protection means the bank will loan you the money needed to cover the check that cannot be covered by funds in the account. True or false ASAP HELP PLEASE
True. Overdraft protection is a service offered by banks to their customers. When your account does not have enough money to cover a transaction, overdraft protection allows the bank to loan you the necessary funds to complete the transaction.
If you make a purchase or withdrawal that exceeds your account balance, the bank will cover the shortfall by lending you the needed amount. This ensures the transaction goes through, but typically comes with fees or interest. While convenient, it can lead to extra costs if used frequently.
Overdraft protection may apply to debit card purchases, checks, or automatic bill payments, depending on the account settings. Some banks offer this service automatically, while others require customers to opt in. It's a useful safety net but should be used responsibly to avoid accumulating unnecessary charges.

Which ordered pair is the best estimate for the solution of the system of equations?
y=−34x−2y=x+6
(−4.25,1.5)
(−4.75,1.75)
(−4.5,1.5)
(−4.5,1.75)
The best estimate for the solution of the system of equations is (-4.5, 1.5).
Explanation:The system of equations given is:
y = -34x - 2
y = x + 6
To find the best estimate for the solution, we can substitute the x-coordinate from each ordered pair into the second equation and solve for y.
Let's check each option:
For (-4.25, 1.5):
1.5 = -4.25 + 6
1.5 = 1.75 (not equal)
This is not a solution for the system.
For (-4.75, 1.75):
1.75 = -4.75 + 6
1.75 = 1.25 (not equal)
This is not a solution for the system.
For (-4.5, 1.5):
1.5 = -4.5 + 6
1.5 = 1.5 (equal)
This is a solution for the system.
For (-4.5, 1.75):
1.75 = -4.5 + 6
1.75 = 1.5 (not equal)
This is not a solution for the system.
Therefore, the best estimate for the solution of the system of equations is (-4.5, 1.5).

Solve for z. 7-~-3z+2=4 What is the root? If there is no root, choose none.
Desmos is Function Calculator is a great tool for this, the correct answer is z= 7/3
7/3= 2.333~ and so √(3*2.333~) + 2= 2.9999999833333~
Now 7- 2.9999999833333~= 4.0000000166667~ but I don't know the true infinate sign for this so thats why my numbers look a little werid, just plug (7/3) in for z and you will get 4, trust me
The root of the given equation 7-[tex]\sqrt{3z+2}[/tex] = 4 is z = 7/3
What is an equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, an equation 7-[tex]\sqrt{3z+2}[/tex] = 4
Solving for z,
7-[tex]\sqrt{3z+2}[/tex] = 4
[tex]\sqrt{3z+2}[/tex] = 3
Squaring both sides,
3z + 2 = 9
3z = 9-2
3z = 7
z = 7/3
Hence, the root of the given equation 7-[tex]\sqrt{3z+2}[/tex] = 4 is z = 7/3
