In June, you bought 14.5 gallons of gasoline for $3.18 per gallon. The following February, you bought the same amount of gasolin

Nata [24]

Answer:

14.5 × 3.18 - 14.5 x 1.88

You paid $18.85 more in june than in February

Step-by-step explanation:

In order to find the answer to this question you will need to find how much you paid in June and how much you paid in February.

ex.14.5 x 3.18 - 14.5 x 1.88

To solve this you need to find the product of 14.5 x 3.18 and 14.5 x 1.88 and then subtract them from eachother.

ex.14.5 x 3.18 =46.11

14.5 x 1.88=27.26

46.11-27.26=18.85

Suppose that 8% of the general population has a disease and that the test for the diesease is accurate 70% of the time. What is

balu736 [363]

Answer:

P = 0.332

Step-by-step explanation:

The probability of having the disease is 0.08

The probability that the test predicts with accuracy is 0.7.

We need to find the probability that the test positive for the disease.

Several cases may occur.

Case 1.

You have the disease and the test predicts it accurately

$P_1 = 0.08(0.7) = 0.056$

Case 2

You do not have the disease and the test predicts that you have it

$P_2 = 0.92(0.3) = 0.276$

Then the probability that the test predicts that you have the disease is the union of both probabilities P1 and P2

$P = P_1 + P_2\\\\P = 0.056 + 0.276\\\\P = 0.332$

10 points. Please help me with numbers 9-13. Numbers 9-13 is the picture.

Answer:

x = 18

y = 15

Step-by-step explanation:

Remark

Step One

The main step is to realize that if the lower left hand angle is 90 degrees, then the upper left hand angle is also 90. That is because the interior angles of parallel lines are supplementary. If one of the angle is 90 degrees, so is the other.

Conclusion from the Remark

5x = 90

x = 90/5

x = 18 degrees

Step Two

Find y

y is just a bit harder to find . The safest way is to add all four interior angles together. For any trap*zoid (you cannot spell this word properly. The editor has a fit), the interior angles add up to 360 degrees.

So just add the 4 angles together and equate to 360

5(y + 11) + 4y - 10 + 90 + 90 = 360 Combine like terms

5(y + 11) + 4y - 10 + 180 = 360 Combine again

5(y + 11) + 4y + 170 = 360 Subtract 170 from both sides

5(y + 11) + 4y = 360 - 170 Combine like terms

5(y + 11) + 4y = 190 Remove the brackets

5y + 55 + y4 = 190 Combine like terms

9y + 55 = 190 Subtract 55 from both sides.

9y = 190 - 55

9y = 135 Divide by 9

y = 135 / 9

y = 15

lilavasa [31]

Answer:

<h2>Irrational </h2>

Step-by-step explanation:

Firstly, 

According to rational and irrational,

$\sqrt{15} \: is \: irrational$

Since,

Natural numbers, Whole Numbers and Integers all come under Rational number.

Hence,

 $\sqrt{15}$ 

Is an irrational number.
