Answer:she had 11 video games on Monday.

Step-by-step explanation:

Let x represent the number of video games that Susie had initially.

On Tuesday, Susie buys three new video games from the store. This means that the total number of video games that Susie had would be x + 3

On Wednesday, she sells half of her video games in order to make extra money. This means that the number of video games that she sold is

(x + 3)/2. The number of video games left would be

x - (x + 3)/2

If she has 4 video games left after selling, it means that

x - (x + 3)/2 = 4

2x - (x + 3) = 8

2x - x - 3 = 8

x - 3 = 8

x = 8 + 3 = 11

Lin's sister has a checking account. If the account balance ever falls below zero, the bank charges her a fee of $5.95 per day.
VladimirAG [237]

Answer: No, the bank will not keep charging her the $5.95 after the deposit is made.

Step-by-step explanation:

Today, Lin's sister's balance is -$2.67

She gets charged $5.95 per day.

There are 14 days until she can charge some money in the bank account, so the bank will charge $5.92 14 times

So her balance after 14 days will be:

Balance = -$2.67 - $5.95*14 = -$85.97

When she charges the $430 in the account, her balance will be:

Balance = -$85.97 + $430 = $344.03

So now she has a positive balance, which means that the bank does not charge her anymore.

Round 314550 to 1 significant figure​
Sauron [17]
300000 all you had to do was round the number down after the 1 significant figure

you round down with
1,2,3,4

and round up with
5,6,7,8,9

so if it asked for 78453
to 2 significant figures you count the numbers and round after that
so 78|453 and since 4 is the next number and it is less that 5 we round down which means it becomes 78000 with is lower than 78453

but if we had 0.0247
and it asked for this number to 2 significant figures all you need to do is count the SIGNIFICANT figures significant means anything with value so that is 1,2,3,4,5,6,7,8,9,10.... 0 has no value therefore we ignore 0 and start counting at the first figure larger than 0
if we go back to 0.0247 that would be the 2 so 2 significant figure of 0.0247 would equal
0.024|7
7 is larger than 5 so we round up to
0.025

irina [24]

Using it's concept, it is found that the experimental probability that the first vehicle rented today will be a pickup truck is of 0.5 = 50%.

<h3>What is a probability?</h3>

A probability is given by the<u> number of desired outcomes divided by the number of total outcomes</u>. For an experimental probability, these number of outcomes are taken from previous trials.

In this problem, we have that out of 4 vehicles, 2 are pickup trucks, hence the experimental probability is given by:

p = 2/4 = 1/2 = 0.5.
