katen-ka-za [31]
<h2>Answer:</h2>

<em><u>Driver experiences 17.68 G's on an average.</u></em>

<h2>Step-by-step explanation:</h2>

In the question,

We know that in a car crash the speed of the car goes from the <u>speed of 26 m/s to 0 m/s</u> in <u>0.15 seconds</u>.

So,

The final speed, v = 0 m/s

Initial speed, u = 26 m/s

Also,

Time in seconds, t = 0.15 s

So,

Using the equation of law of the motion, we get,

v = u + at

0 = 26 + a(0.15)

a = -26/0.15

<u>a = -173.33 m/s²</u>

As, there is deceleration of the car is taking place the acceleration is in negative.

Now,

To convert it into the force in the <u>G's</u> we need to divide the <u>deceleration</u> by the <u>acceleration (gravity), g.</u>

So,

<u>G's experienced by the driver on an average</u> is given by,

\frac{173.33}{9.8}=17.68

<em><u>Therefore, on an average the driver experiences 17.68 G's.</u></em>

A bag contains an unknown number of marbles. You know that P(red) = 1 and P(green) = 1. What can you conclude about how many mar
Nataly [62]

The number of marbles in the bag illustrates probability

The conclusion about the number of marbles in the bag is that the bag can only contain one type of marble

<h3>The number of marbles in the bag?</h3>

The probabilities are given as:

P(Red) = 1

P(Green) = 1

For a distribution, the sum of all probabilities must equal to 1.

This means that:

P(Red) + P(Green) = 1

So, we have:

1 + 1 = 1

This gives

2 = 1

The above equation is false because 2 does not equal to 1.

So, the conclusion about the number of marbles in the bag is that the bag can only contain one type of marble i.e. either red marbles are in the bag or blue marbles are in the bag

Mafalda has a save percentage of 0.7380.7380, point, 738 so far this hockey season. Last season, her save percentage was 0.5850.
Snowcat [4.5K]

Answer:

0.153

Step-by-step explanation:

We have been given that Mafalda has a save percentage of 0.738 so far this hockey season. Last season, her save percentage was 0.585.

To find improvement in Mafalda's save percentage we will subtract last season's save percentage from this season's save percentage.

0.738-0.585=0.153

Therefore, Mafalda's save percentage improved by 0.153.

I want to put $580 until I saving account for one year. The rate of interest On the account was 6 1/2%. How much was the interes
Vanyuwa [196]

Answer:

The amount of interest earned for the year is $37.7

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents principal or amount invested.

T represents the time

R represents the interest rate

I represents the interest

From the information given,

You want to put $580 into a saving account for 1 year. This means that

P = $580 and

T = 1 year

R = 6 1/2 = 6.5%

I = (580× 6.5×1)/100 = $37.7
