Suppose you select a card at random from a standard deck of cards 60 times, and 12 of those selections are hearts. How does the experimental probability compare to the theoretical probability? Include the difference between both types in your explanation.
A standard deck is composed of 52 cards, and contains 13 cards per suit. So, the theoretical probability of picking a card of any suit (and thus, in particular, a heart) is given by
[tex]P(\text{hearts}) = \dfrac{\text{\# of hearts in the deck}}{\text{\# of cards in the deck}} = \dfrac{13}{52} = \dfrac{1}{4}[/tex]
On the other hand, the experimental probability is (as the name suggests) the probability that we can deduce from our experiment: we picked 60 cards, and 12 of these were hearts. This means that it would seem to us that
[tex]P(\text{hearts}) = \dfrac{\text{\# of hearts we picked}}{\text{\# of cards we picked}} = \dfrac{12}{60} = \dfrac{1}{5}[/tex]

The ratio of Sam’s height to joe’s height is 5:6. Sam is 57”tall, how tall is joe
Joe is 68.4” tall. Set the ratio of 5/6=57/x, solve using the butterfly method (multiply 57 and 6, set equal to 5x) 57•6 is 342, so at this point it would be 342=5x. 342/5 is 68.4

Find the shaded region?
trapezoid: (25+19)/2 *20 (see formula for area of a trapezoid)
and the smaller parallelogram: (10*17) (see formula for parallelogram)
and subtract the parallelogram from the trapezoid and you're done!
so we have a trapezoid with a parallelogram inside.
now, if we just get the area of the trapezoid, which includes the parallelogram, and then get the area of the parallelogram and subtract it from that of the trapezoid, what's leftover is the shaded region, because we'd be in effect making a "hole" in the trapezoid and the area leftover is the shaded part.

Factor the trinomial 6x^2+5x- 25
Answer:
x = 5/3 or x = -5/2
(3x-5) or (2x+5)
Step-by-step explanation:
Given in the question an equation
6x²+5x- 25
here a = 6
b = 5
c = -25
To solve the polynomial equation we will use quadratic equation
x = -b ±√(b²-4ac) / 2a
Plug values in the equation
-5±√(5²-4(6)(-25)) / 2(6)
-5±√(25 + 600) / 2(6)
-5±√(625) / 2(6)
-5± 25 / 2(6)
-5 + 25 / 2(6) or -5 - 25 / 2(6)
x = 5/3 or x = -5/2

Business services ordered a chair that cost $220.59. Upon arrival they received an invoice for $261.47. If the California sales tax rate is 7.9% what is the cost of shipping and handling
Answer:
Cost of shipping and handling = $23.453
Step-by-step explanation:
Given
Price of Chair=$220.59
Tax=7.9%
Invoice Price=$261.47
In order to find the cost of shipping and handling, we have to subtract the cost of chair and the tax from the invoice price of chair.
To find the tax,
Tax amount=220.59*0.079
=$17.42661
Now,
Cost of shipping and handling=$261.47-$220.59-$17.42661
=$23.453 ..
Answer:
The cost of shipping and handling is $23.45 .
Step-by-step explanation:
As given
Business services ordered a chair that cost $220.59.
if the California sales tax rate is 7.9%
7.9% is written in the decimal form
[tex]= \frac{7.9}{100}[/tex]
= 0.079
Thus
Sales tax price = 0.079 × Cost of the chair
= 0.079 × $220.59
= $ 17.43 (Approx)
Thus
Cost of the ordered chair with sales tax price = Cost of the chair + Sales tax price .
= $ 220.59 + $17.43
= $ 238.02
As given
Upon arrival they received an invoice for $261.47.
Thus
Cost of shipping and handling = Cost mentioned in invoice - Cost of the ordered chair with sales tax price.
Put all the values in the above
Cost of shipping and handling = $261.47 - $238.02
= $ 23.45
Therefore the cost of shipping and handling is $23.45 .

Convert the angle 0=133π/72 radians to degrees
The result is 332.5 degrees.
To convert an angle from radians to degrees, we use the conversion factor that 1 radian = 180/π degrees. In this case, the angle is 133π/72 radians.
So, to convert 133π/72 radians to degrees, we multiply by the conversion factor:
(133π/72) * (180/π) degrees.
Solving this gives us the angle in degrees:
133 * 180 / 72 = 332.5 degrees.

A circle is centered at the point (-7, -1) and passes through the point (8, 7).
The radius of the circle is_____ units. The point (-15, ___) lies on this circle.
Answer:
1. r=17
2. (-15,14) or (-15,-16)
Step-by-step explanation:
The radius of the circle is the distance from the center to the point on the circle, thus
[tex]r=\sqrt{(8-(-7))^2+(7-(-1))^2}=\sqrt{15^2+8^2}=\sqrt{225+64}=\sqrt{289}=17.[/tex]
The equation of the circle is
[tex](x-(-7))^2+(y-(-1))^2=r^2\\ \\(x+7)^2+(y+1)^2=289.[/tex]
If point lies on this circle, then its coordinates satisfy the circle's equation:
[tex](-15+7)^2+(y+1)^2=289\\ \\64+(y+1)^2=289\\ \\(y+1)^2=225\\ \\y+1=15\text{ or }y+1=-15\\ \\y=14\text{ or }y=-16[/tex]
the radius of the circle is 17 units.
the two possible points on the circle are (-15, 14) and (-15, -16).
The question requires calculating the radius of a circle given two points: the center of the circle and a point on the circumference. To find the radius, we will use the distance formula, which is derived from the Pythagorean theorem. The distance formula to find the distance between two points (x1, y1) and (x2, y2) is \\(
√{(x2 - x1)^2 + (y2 - y1)^2}\\).
Applying the distance formula with the center at (-7, -1) and a point on the circle being (8, 7), we get: \\(
√{(8 - (-7))^2 + (7 - (-1))^2}) = (√{(15)^2 + (8)^2}) = (√{225 + 64}) = (√{289}) = 17. Thus, the radius of the circle is 17 units.
To find the missing y-coordinate of the point (-15, ___) that lies on this circle, we use the circle's equation with its center at (-7, -1): ((x + 7)^2 + (y + 1)^2 = 17^2). Substituting x = -15, we solve for y.
((-15 + 7)^2 + (y + 1)^2 = 17^2)
((-8)^2 + (y + 1)^2 = 289)
64 + (y + 1)^2 = 289
(y + 1)^2 = 225
y + 1 = (√{225}) or y + 1 = -(√{225})
y = 14 or y = -16
Therefore, the two possible points on the circle are (-15, 14) and (-15, -16).

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 the probability of testing positive for the disease
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
[tex]P_1 = 0.08(0.7) = 0.056[/tex]
Case 2
You do not have the disease and the test predicts that you have it
[tex]P_2 = 0.92(0.3) = 0.276[/tex]
Then the probability that the test predicts that you have the disease is the union of both probabilities P1 and P2
[tex]P = P_1 + P_2\\\\P = 0.056 + 0.276\\\\P = 0.332[/tex]
