When the insurance company want a plan with a deductible of $4,000, they need to charge a minimum of $18000 for premiums.

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

It should be noted that a deductible simply means the amount of money that is paid out of the pocket of the policy holder.

From the information given, each accident costs $18,000 on average. Therefore, this is the minimum amount of premium.

When they want a plan with a premium of $1,000, the amount that they'll need to charge for deductibles will be:

= (4000/18000) × 1000

= $220

If a single card is drawn from a standard 52-card deck, what is the probability that it is an ace or a spade?
klasskru [66]

A 52-card deck is made up of an equal number of diamonds, hearts, spades, and clubs. Because there are 4 suits, there is a 1/4 chance to draw one of them, in our case, spades.

There are 4 aces in a 52-card deck, so the chance of drawing one is 4/52, or 1/13.

The question asks for the probability of drawing an ace or a spade. Because it uses the word "or," we add the probabilities together. This is because there is a chance of drawing either of the cards; it doesn't have to meet both requirements to satisfy the statement.

However, if the question were to say "and," we would multiply the two probabilities.

Let's add 1/4 and 1/13. First, we can find a common denominator. We can use 52 because both fractions can multiply into it (since the ratio came from a deck of 52 cards as well).

\frac{1}{4} -- > \frac{13}{52}

\frac{1}{13} -- > \frac{4}{52}

Now we can add them together.

\frac{13}{52} + \frac{4}{52} = \frac{13+4}{52} = \frac{17}{52}

This cannot be simplified further, so the probability is 17 in 52, or 33%.

hope this helps!

X+1/2(x-4)=1/2x+6(x-2)
Andrej [43]

Answer:

B) 1

Step-by-step explanation:

x+1/2(x-4)=1/2x+6(x-2)

x+1/2x-4/2=1/2x+6x-12

x+1/2x-1/2x-2=6x-12

x-2=6x-12

x-6x-2=-12

-5x-2=-12

-5x=-12+2

-5x=-10

5x=10

x=10/5

x=2

On Monday, Lou drives his ford escort with 28-inch tires, averaging x miles per hour. On Tuesday, Lou switches the tires on his
weeeeeb [17]

Answer:

\% Change = \frac{|28-32|}{32} *100 = 12.5\%

(B) Decrease by 12.5%

Step-by-step explanation:

For this case we know that the revolution is proportional to the circumference.

And we know that the average number of revolutions of 32 inch tires for Tuesday is higher than the original value of 28 inch tires for Monday.

We know that we have x mi/hr, so we can select a value fo x in order to find the average revolutions with the following formula:

Avg = \frac{x}{mi}

Let's say that we select a value for x for example x= 28*32 = 896, since this value is divisible by 32 and 28.

If we find the average revolutions per each case we got:

Tuesday:

Avg = \frac{896}{32}=28

Monday:

Avg = \frac{896}{28}=32

And then we can find the % of change like this:

\% Change= \frac{|Final-Initial|}{Initial} *100

And if we replace we got:

\% Change = \frac{|28-32|}{32} *100 = 12.5\%

Because we are assuming that the initial amount is the value for Monday and the final value for Tuesday.

So then the best answer for this case would be:

(B) Decrease by 12.5%

Ganezh [65]

Answer:

See below ~

Step-by-step explanation:

<u>Q1</u>

  • y = (x + 3i)(x - 7)
  • y = x² + 3ix - 7x - 21
  • <u>y = x² + (3i - 7)x - 21</u>

<u>Q2</u>

  • y = (x - √5)(x - i)
  • y = x² - √5x - ix + √5i
  • <u>y = x² - (√5 + i)x + √5i</u>
