A. $2.78Step-by-step explanation:You would multiply the cost per pound, $2.14, by the amount of pounds bought, 1.3. Then round to the nearest hundredth.2.14 x 1.3 = 2.7822.782 rounded to the nearest hundredth is $2.78

Step-by-step explanation:

In Total there are 43 jelly beans, which means that will be our denomintor.(sorry if i spelled that wrong)

12/43 are red      17/43 are white        14/43 are black = 43/43

27.9% of 43       +   39.5% of 43       +   32.6% are black = 100%

There is the highest chance that the jelly beans chosen will be white, with black following. 2 white & 3 black would be 5/43 which is 11.6% of the jelly beans in total. Of this chance there is about a 25% chance that white will be chose & 27-30% chance that black will be chosen.

Answer:

George = 10 + 0.5x

Carlee = 13 + 0.25x

Step-by-step explanation:

Let x be the amount they manufacture, each time they make an object, their pay will increase by the set amount meanwhile the 10 and 13 are a set amount of pay that they will receive.

Answer:

Parallel lines have the same slope, so in y = mx +b, m would have the same value for both.

In perpendicular lines, the value of the m is inversed. Because the m is over an invisible one in this case, m/1(x) becomes -1/m(x), making the equation y = 1/m(x) + b

Point-slope form is (y - y1) = m (x - x1), meaning that the first term of y subtracted from the zeroth term of y is equivalent to m multiplied by the value of the first term of x from the zeroth term of x

Kinetic Energy Formula: [tex]KE = \frac{1}{2} mv^2[/tex]

Potential Energy Formula: [tex]PE=mgh[/tex]

Explanations:

For KE:

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

For PE:

In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength (9.8 N/kg on Earth) - sometimes referred to as the acceleration of gravity.

Answer:

(x-4)^2 + (y-5)^2 = 20

Step-by-step explanation:

Rearrange the line equation of 5x - 2y + 6 = 0

So y = 5/2x +3

The y-intercept of the line equation is 3 as when x=0, y=3.

We know the Circle has the formula [tex](x-4)^2 + (y-5)^2 = ?^2[/tex] from the question but with the intercept, we can find the entire equation as the y-intercept is (0,3) so we can substitute it into the equation to find the full equations so:

[tex](0-4)^2 + (3-5)^2 = ?^2[/tex]

This simplifies to:

[tex](-4)^2 +(-2)^2[/tex] = [tex]?^2[/tex]

16 + 4 = 20 = [tex]?^2[/tex]

The answer is 20 so the equation of the circle is [tex](x-4)^2 + (y-5)^2 = 20[/tex]

The exchange rate of US dollars to Polish zloty is 1:3.1264. The correct option is b. 1:3.1264

From the question, we are to determine the exchange rate of US dollars to Polish zloty

From the given information,

Gary exchanged US dollars for Euros at a rate of 1:0.7716

That is,

1 US dollar = 0.7716 Euros

Also, he exchanged Euros for Polish zloty at a rate of 1:4.0518

That is,

1 Euro = 4.0518 Polish zloty

Now, we will find the value of 0.7716 Euros in Polish zloty

Since 1 Euro = 4.0518 Polish zloty

Then,

0.7716 Euro = 0.7716 × 4.0518 Polish zloty

∴ 0.7716 Euro = 3.1264 Polish zloty

But

1 US dollar = 0.7716 Euros

Therefore,

1 US dollar = 3.1264 Polish zloty

Hence, the exchange rate of US dollars to Polish zloty is 1:3.1264. The correct option is b. 1:3.1264

Answer:

  7.07 years

Step-by-step explanation:

The standard deviation of a population is easily calculated by a spreadsheet or calculator. Care must be taken to use the formula for population standard deviation, rather than the formula that assumes the values are a sample.

__

The attached calculator shows the standard deviation is about 7.07 years.

_____

Additional comment

The population standard deviation is the square root of the variance. The variance is the mean of the squares of the values, less the square of the mean of the values. The second attachment shows the calculation done this way.

The units of standard deviation are the same as the units of the members of the population. Here, that is "years."

If he makes his trade on the day with the least favorable exchange rate, the amount received is ins 38.35

From the complete question, we have the following parameters:

£1= 0.47 --- least favorable rate

Given that the uses a charge of 8%, the amount received when he converts  £88.65 is calculated using:

Amount = Rate * Amount * (1 - 8%)

So, we have:

Amount = 0.47 * 88.65 * (1 - 8%)

Evaluate the product

Amount = 38.33

The closest amount to 38.33 is 38.35.

Hence, the amount received is ins 38.35

Answer:

The mean expense is approximately equal to 53.714

Step-by-step explanation:

When you are trying to find the mean of a number set, you are trying to find the average of the stats. As such, use the formula Sum of the Numbers / Total Number of Values.

In this case, we are adding 54 + 61 + 42 + 63 + 42 + 56 + 58, which is equal to 376. We are then dividing this by 7, which is equal to about 53.714.

There fore the answer is  y=(-1/2)x +2

Step-by-step explanation:

Find straight line question passing through the points (-4,4) and (8,2)

Use formula (y-y1) (x2-X1) = (y2-V1) (x-x1)

(y-Y1) (x2-X1) = (y2-Y1)(x-x1)

Substitute points in formula

(y-4)(8+4) = (-2-4) (x+4)

(y-4)12=-6(x+4)

y-4=(-1/2) (x)-(2)

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

y=(-1/2)x +2

Answer:

√216 meters

Step-by-step explanation:

» Concepts

The Pythagorean theorem states that in a right triangle, the sum of the squares of the legs is equal to the length of the hypotenuse squared. It's represented as an equation of a² + b² = c², where a & b are the legs, and c is the hypotenuse

» Application

To find the length of the other leg, we have to plug in the values of b and c into the equation. B would be 15 meters, and c would 21 meters.

» Solution

Step 1: Simplify both sides of the equation.

Step 2: Subtract 225 from both sides.

Step 3: Take square root of both sides.

Therefore, the length of the other leg is √216 meters.

Answer:

EH = 120 degrees

Step-by-step explanation:

angles in a circle add up to 360 degrees

arc EF + arc FG + arc GH + arch EH = 360

95 + 90 + 55 + EH = 360

240 + EH = 360

subtract 240 from both sides to isolate EH

EH = 120 degrees

Answer:

1/3 or 1:3

Step-by-step explanation:

since there is a 10/30 chance

to simplify divide by 2

10/30 ÷ 2/2 = 5/15

then divide by 5

5/15 ÷ 5/5 = 1/3

your answer is 1/3

another simple way to simplify

since there is a zero (0) in both the ones (1s) spot on both the numerator and denominator in 10/30, you may just cross out both zeros (0s) to simplify the value

10/30 simplified/taken away 0s = 1/3
