Answer:

Since he started with $24 in his account, on addition of $7 weekly, the first 8 numbers will be 31,38,45,52,59,66,73

Step-by-step explanation:

Opening savings balance = $24

every week he earns $15 for babysitting out of that he spends eight dollars and save the rest hence

Amount saved weekly = 7

To find the first 8 numbers in his pattern, the pattern can be shown using the arithmetic progression formula.

Tₙ = a + (n - 1)d where n is the number of term, d is the common difference and Tₙ is the nth term

In this instance, a =24, d= 7

therefore Tₙ = 24 + (n - 1)7

Tₙ = 17 + 7n

T₁ = 24

T₂ = 17 + 7(2) = 31

T₃ = 17 + 7(3) = 38

T₄ = 17 + 7(4) = 45

T₅ = 17 + 7(5) = 52

T₆ = 17 + 7(6) = 59

T₇ = 17 + 7(7) = 66

T₈ = 17 + 7(8) = 73

T₉ = 17 + 7(9) = 80

The numbers are 31,38,45,52,59,66,73

Solve the system of equations and choose the correct ordered pair. 
Ksivusya [100]
L.H.S is already equal, so just subtract 1st equation from second, 
2y = 12
y = 6

Now, substitute it in 1st equation, 
2(6) = 4x + 8
4x = 12 - 8
x = 4/4
x = 1

In short, Your Answer would be Option C) (1, 6)

Hope this helps!

Problem 2 (4 points) The Better Business Bureau conducts a survey of
Georgia [21]

The probability that all three would recommend their attorney to a friend is 18.19%, and the probability that the first would not, but the second and third would recommend their attorney to a friend is 8.56%.

<h3><u>Probabilities</u></h3>

Since the Better Business Bureau conducts a survey of 30 people who recently hired an attorney, and 17 of them say that they would recommend their attorney to a friend, while 8 say that they would not recommend their attorney to a friend, and the remaining 5 say that they are not sure, and then three people are selected from this group of 30 people at random, to determine what is the probability that A) all three would recommend their attorney to a friend, and B) the first would not, but the second and third would recommend their attorney to a friend, the following calculation must be performed:

A)

  • 17/30 x 17/30 x 17/30 = X
  • 0.5666 x 0.5666 x 0.5666 = X
  • 0.1819 = X

B)

  • 8/30 x 17/30 x 17/30 = X
  • 0.2666 x 0.5666 x 0.5666 = X
  • 0.0856 = X

Therefore, the probability that all three would recommend their attorney to a friend is 18.19%, and the probability that the first would not, but the second and third would recommend their attorney to a friend is 8.56%.

X^4=15 <br> is an exponential equation?
miskamm [114]

Answer:

No. It is not an Exponential Equation.

Step-by-step explanation:

Givenx^{4} =15

By the Definition of Exponential Equation which states.

"The equation is said to be an exponential equation when it has a variable occurred in the exponent and which have the same base."

For Example:

All given below are said to be exponential equations.

5^{x} =5^{2} \\7^{x}=49\\

which can be rewritten as

7^{x}=7^{2}

Now in the given equation x^{4}=15 it doesn't have same base neither any means the base can be made same,hence the given equation is not an exponential equation
