Answer:

The expected value of the proposition is -$0.76.

Step-by-step explanation:

It is provided that a basketball player has made 291 out of 389 free throws.

Then rate of him making a free throw is,

[tex]P(\text{free throw})=\frac{291}{389}=0.7481[/tex]

The probability that he makes the next 2 free throws is:

[tex]P(\text{Next 2 free throws})=(0.7481)^{2}=0.5596[/tex]

The payout rules are:

Compute the expected value of the proposition as follows:

Expected value = $38 × P (Makes both) + (-$50) × P (Misses both)

                          [tex]=($38\times 0.5596)+(-$50\times (1-0.5596))\\=21.2648-22.02\\=-0.7552\\\approx -$0.76[/tex]

Thus, the expected value of the proposition is -$0.76.

Step-by-step explanation:

7d+4d-3d=40

8d=40

40/8=x

x=5

if it was addition

Answer:

The fractions are not equivalent. If you cross multiply 65 x 2 = 130 and 4 x 13 = 52. 130 > 52. Set them as a proportion. [tex]\frac{65}{4} = \frac{13}{2}[/tex]

They are not equal.

For 65/4 you cannot divide it by 2 and then get 13/2. You would get 32.5/2.

32.5/2 is not equal to 13/2

It is better to use the metric system, rather than the English system, in scientific measurement because,

The metric system uses one unit for each category of measurement.

A system of measurements is called the metric system. It is employed in calculations and research across the globe.

Measurements for length include millimeters (mm), decimeters (dm), centimeters (cm), meters (m), and kilometers (km).

A foot equals 30.48 cm, however, a popular 30 cm rule measures every 1 cm, therefore the metric system also provides more exact measurements.

The English system is in fact based on the metric system because they look for reference materials to get the measurements.

Answer:

its 3.05

Step-by-step explanation:

The coordinates of A will be at (-10, -5) when the transformation (x,y) → (x + 10, y + 5) is  performed on point A.

Given the coordinate of the resulting image after the transformation is A'(0, 0). We need to get the coordinate of the original image A.

Since the transformation (x,y) → (x + 10, y + 5) is performed on A.

A = (0 - 10, 0 - 5)

If we are going from the pre-image to the image, we will translate to the left and downwards

A = (-10, -5)

Hence the coordinates of A will be at (-10, -5)

Step-by-step explanation:

the integer that represents the total charge of 7 electrons is -1.The total charge of electrons is given by the formula:

total charge = number of electrons x charge of each electron

what are electrons ?

Electrons are subatomic particles that carry a negative electric charge. They are one of the fundamental particles that make up atoms, along with protons and neutrons. Electrons are found in shells or energy levels that surround the atomic nucleus

In the given question,

The total charge of electrons is given by the formula:

total charge = number of electrons x charge of each electron

The charge of an electron is a fundamental constant, which is equal to -1.602 x 10⁻¹⁹ Coulombs. Therefore, the total charge of 7 electrons can be calculated as:

total charge = 7 x (-1.602 x 10⁻¹⁹) C

total charge = -1.1214 x 10⁻¹⁸ C

Note that the charge of an electron is negative because it has an opposite charge to the positively charged protons in an atom. Therefore, the total charge of 7 electrons is also negative. To express this charge as an integer, we need to convert it to scientific notation and round to the nearest whole number. Rounding to the nearest whole number gives:

total charge = -1 x 10⁻¹⁸ C

Therefore, the integer that represents the total charge of 7 electrons is -1.

Answer:

8 parties

Step-by-step explanation:

First, find how much of her paycheck was from working 30 hours:

7.50(30)

= 225

Then, subtract this from 265, to find how much money was from bonuses:

265 - 225

= 40

To find how many parties she scheduled, divide 40 by 5, since each party she schedules gives her a $5 bonus:

40/5

= 8

So, she scheduled 8 parties

Answer:

m=10

Step-by-step explanation:

Answer:

m=10

Step-by-step explanation:

9(m+5)−3(m−2)=8m+31

Step 1: Simplify both sides of the equation.

9(m+5)−3(m−2)=8m+31

9m+45+−3m+6=8m+31

(9m+−3m)+(45+6)=8m+31(Combine Like Terms)

6m+51=8m+31

Step 2: Subtract 8m from both sides.

6m+51−8m=8m+31−8m

−2m+51=31

Step 3: Subtract 51 from both sides.

−2m+51−51=31−51

−2m=−20

Step 4: Divide both sides by -2.

m=10

2/3x = 6

Multiply each side by 3/2

2/3x*3/2 = 6*3/2

x = 9

Answer:

You add one to both sides, multiply 3 to both sides (to further isolate x), and then divide by 2 on both sides. When you substitute back in, both sides of the equation are equal to each other.

Answer:

The smallest number is 114921 and the cube root of the result is 339

Step-by-step explanation:

The number 339 can be factored as:

339 = 3 * 113

Both factors are prime, thus to produce a perfect cube, we must multiply by each factor to the power of 2, that is:

3^2*113^2=114921

When we multiply 339 by 114921 we get 38958219, a perfect cube which cube root is 339.

Thus, the smallest number is 114921 and the cube root of the result is 339
