Find the value of x.

The probability that you pull a card from a standard deck of 52 and then pull a second card without replacing the first card is 2%

The given parameters are:

Cards = 52

Face card = 12

Ace = 4

The probability of selecting a face card is:

P(Face card) = 12/52

Now, there are 51 cards.

The probability of selecting an ace is:

P(Ace) = 4/51

The required probability is:

P = 12/52 * 4/51

Evaluate

P = 0.0181

Express as percentage

P = 1.81%

Approximate

P = 2%

Hence, the probability is 2%

Step-by-step explanation:

Erika is working on solving the exponential equation 50^x = 17; The solution is x = 0.7242.

When you raise a number with an exponent, there comes a result.

Let's say you get

a^b = c

Then, you can write 'b' in terms of 'a' and 'c' using a logarithm as follows

[tex]b = \log_a(c)[/tex]

'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'

Erika is working on solving the exponential equation 50^x = 17;

however, she is not quite sure where to start.

The equation is

[tex]50^x = 17\\[/tex]

By taking the log both sides

[tex]log_a b = x\\\\a_x = b[/tex]

By using the base formula

[tex]log_0 y = \dfrac{logy}{log b}[/tex]

So, [tex]log_{50} 17= x\\\\[/tex]

[tex]x = \dfrac{log17}{log 50}[/tex]

x = 0.7242

Answer:

-4

Step-by-step explanation:

if you graph it, we can find out two points are 0,17 and 1,13

we can find the slope from rise/run

-4 is the  slope of the line represented by the equation y + 3 = -4(x-5)

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The equation of the line is y + 3 = -4(x-5)

We have to find slope

Let us simplify the equation to slope intercept form to find slope

y+3=-4x+20

y=-4x+17

Hence, -4 is the  slope of the line represented by the equation y + 3 = -4(x-5)

Division problem 6/0 as a multiplication problem = 6×1/0

Simplified solution of the problem = ∞

The division is the process of repetitive subtraction. It is the inverse of the multiplication operation.

Given division problem,

6/0

Division is inverse of the multiplication

∴ 6/0 = 6×1/0

Now, simplifying

6 × 1/0 = 6 × ∞ = ∞

Hence, ∞ is the solution of the division problem 6/0 after converting it into multiplication problem 6 × 1/0.

Step-by-step explanation:

The sequence which shows arithmetic sequence is -3, -10, -17, -24, -31, ....... so the correct option is Option D.

An arithmetic progression (AP) is a sequence where the differences between every two consecutive terms are the same.

Here, out of the given option option D follows the definition.

Difference between two consecutive term is equal.

-10 - (-3) = -10 + 3 = -7

-17 - (-10) = -17 + 10 = -7

-24 - (-17) = -24 + 17 = -7

-31 - (-24) = -31 + 24 = -7

Thus, the sequence which shows arithmetic sequence is -3, -10, -17, -24, -31, ....... so the correct option is Option D.

Answer:

A) 266.39

Step-by-step explanation:

Answer:

a) 266.39 unit^2.

Step-by-step explanation:

Area of the base = 8^2 = 64 .

There are 4 triangular sides.

To find the area of 1 side we need to know the slant height s of the triangle, This can be found using the Pythagoras Theorem

s^2 = 4^2 + 12^2 = 160

s = √160

So the area of 1 side = 1/2 * base * s

= 1/2 * 8 * √160

and

area of 4 sides

=  4 * 1/2 * 8 * √160

= 202.386

So the Surface area of the pyramid

= 64 + 202.386

= 266.386

Step-by-step explanation:

The purchase of the hydroponic system by Ingrid Nilsen for $4,000 with a 20% down payment at 10% APR for 36 months, and the related calculations, are as follows:

a) down payment = $800.00 ($4,000 x 20%)

b) amount financed = $3,200 ($4,000 - $800)

c) monthly payment = $103.25

d) total amount repaid = $4,517

e) finance charge = $517

The amount of the periodic payment, finance charge, and total repayment can be computed using an online finance calculator as follows:

Auto Price = $4,000

Loan Term = 36 months

Interest Rate = 10%

Down Payment = $800 ($4,000 x 20%)

Monthly Payment  = $103.25

Total Loan Amount $3,200.00

Upfront Payment = $800.00 ($4,000 x 20%)

Total of 36 Loan Payments = $3,717. ($103.25 x 36)

Total Loan Interest = $517

Total Cost (price, interest, tax, fees) = $4,517

Thus, Ingrid Nilsen repaid a total of $4,517 with $517 in interest (finance charge).
