Answer:
The solution is (-10,-7)
Step-by-step explanation:
y=2/5x-3 and x=-10
We know x = -10
Substitute the second equation into the first equation to find y
y = 2/5 (-10) -3
y = -4 -3
y = -7
The solution is (-10,-7)
Answer:
The probability that an Audi A8 car with 2.4L engine is selected given that the car failed emissions test taken within four years of purchase is 0.3589.
Step-by-step explanation:
Let's denote event as follows:
<em>A</em> = an Audi A8 car has a 2.0L engine.
<em>B</em> = an Audi A8 car has a 2.4L engine.
<em>C</em> = an Audi A8 car has a 2.8L engine.
<em>X</em> = an Audi A8 car failed emissions test taken within four years of purchase.
The information provided is:

The probability that an Audi A8 car with 2.4L engine is selected given that the car failed emissions test taken within four years of purchase is:

Compute the probability of an Audi A*8 car failed emissions test taken within four years of purchase as follows:

Compute the value of P (B|X) as follows:

Thus, the probability that an Audi A8 car with 2.4L engine is selected given that the car failed emissions test taken within four years of purchase is 0.3589.
$0.81+$9.00=$9.81
Answer: $9.81
We know t<span>o find the total price, first find the amount of sales tax paid by multiplying the sales tax by the original price of the basket of watermelons.
</span><span>9%×$9=<span>?
</span></span>Percent means "out of one hundred," so <span><span><span><span>9% </span></span></span></span> is equivalent to <span>9/100 </span><span>which is also equal to 9 divided by 100.
9 divided by 100 is 0.09
</span>To find the amount of sales tax that must be paid, multiply <span><span>0.09 </span></span><span>by the original price.
So it would be 0.09*$9=$0.81
</span>
<span>To find the final price Tiffany paid, add the sales tax you just found to the original price.
$0.81+$9.00=$9.81
</span>To find the final price Tiffany paid, add the sales tax you just found to the original price.
(100+6.8=106.8%)
106.8\100 x 44000=$46992
Answer:
years 1–4: 62.4 bass per year
years 5–8: 67.6 bass per year
Step-by-step explanation:
If the population in year n is ...
p(n) = 3000·1.02^n
then the average rate of change from year 1 to year 4 is ...
(p(4) -p(1))/(4 -1) = 3000(1.02^4 -1.02^1)/3 = 1020·(1.02^3 -1) ≈ 62.4
The average rate of change for years 1–4 is 62.4 bass per year.
For years 5–8, the rate of change is similarly computed:
(p(8) -p(5))/(8 -5) = 3000(1.02^8 -1.02^5)/3 = 1000·1.02^5·(1.02^3 -1) ≈ 67.6
The average rate of change for years 5–8 is 67.6 bass per year.
