We already know that the speed of light is 299,792 km/s.

225,000,000 km* (1 s/ 299,792 km) ≈ 751 s.
(Note that the unit cancels out so you get the answer)

It takes light about 751 seconds from the Sun to reach Mars~

SAT scores probability 1​
fredd [130]

Answer:

  a.  81.5%

Step-by-step explanation:

The z-score for 400 is ...

  Z = (X -μ)/σ = (400 -500)/100 = -1

The z-score for 700 is ...

  Z = (700 -500)/100 = 2

The empirical rule tells you that 68% of the distribution is within ±1σ of the mean, and 95% is within ±2σ of the mean. Half of that first number is in the range Z = -1 to 0, and half that second number is in the range Z = 0 to +2. So, the probability you want is ...

  (1/2)(68%) + (1/2)(95%) = 81.5% . . . . matches choice A

please help me A portion of Taquan's check register is shown. Before Taquan made his utility payment on March 24, the balance of
Natalka [10]

The check register is used to show the total amount Taquan spent

Using the assumed values, Taquan's initial balance is $1336.26

<h3>How to determine the amount before making the utility payment?</h3>

The question is incomplete, as the check register is not shown.

So, I will give a general explanation

Assume that the utility bill is $241.46

From the question, the new balance on March 24 is $1094.80

This means that the initial balance is:

Initial balance = New balance + Utility bill

This gives

Initial balance = $1094.80 + $241.46

Evaluate the sum

Initial balance = $1336.26

Using the assumed values, Taquan's initial balance is $1336.26
