Answer:

Answer A: 16/25

Answer B: 2/24

Step-by-step explanation:

There are 16 dark chocolates, so the probability of choosing one is 16/25. the total number of candies is 25, so when one  is eaten, the number changes to 24. There are 2 caramels, so the number is 2/24.

Answer:

21

Step-by-step explanation:

2³ = 8

8/2

= 4

3.4(5)

= 17

4 + 17

= 21

Answer:

Your answer is going to be: 21.

Step-by-step explanation:

In this problem, we're going to be using PEMDAS.

[tex]\frac{1}{2} x^{3} +3.4y[/tex]

Now, we have to fill the blanks:

[tex]\frac{1}{2} 2^{3} +3.45[/tex] [tex](5)\\[/tex]

There's no parenthesis (3.45(5) is just another way of multiplying so that doesn't count). So, we move to the exponent part.

[tex]\frac{1}{2} 8+3.4(5)[/tex]

Everything else is just multiplication.

[tex]\frac{8}{2} + 17[/tex] = 4+ 17

Add it all together and your answer is going to be:

21.

P.S. Good luck with the rest of your assignment!!

Step-by-step explanation:

You can check it before choosing the answer.

I think 85% correct.

Answer:

B(5,2)

Step-by-step explanation:

Answer:

d = 5

Step-by-step explanation:

The common difference d is the difference between consecutive terms in the sequence

- 29 - (- 34) = - 29 + 34 = 5

- 24 - (- 29) = - 24 + 29 = 5

- 19 - (- 24) = - 19 + 24 = 4

Thus the common difference is d = 5

The common difference between consecutive terms in the given sequence is 5.

The given sequence is {-34, -29, -24, -19, ...}

To find the common difference, we need to look for a pattern between consecutive terms. So, let's observe the differences between consecutive terms:

-29 - (-34) = 5

-24 - (-29) = 5

-19 - (-24) = 5

As we can see, the common difference between consecutive terms is 5.

In a square, all four sides are the same length. Imagine a square that has been cut by a diagonal. We have two triangles, each with the same length hypotenuse (diagonal length) and two equal side lengths. To find the length of each side, we can use the Pythagorean theorem.

I used x in place of a and b, as both side lengths are equal.

x^2 + x^2 = (28 [tex]\sqrt{2}[/tex])^2

2x^2 = 1568

x^2 = 784

x = 28

The length of each side is 28 units.

Hope this helps!! :)

Answer:

Once it is a square, the lengths are the same. Considering that

a square's diagonal is [tex]s\sqrt{2}[/tex], thus, each length measures 28.

You may use the pythagorean theorem:

[tex](28\sqrt{2} )^2=s^2+s^2\\28\sqrt{2} =\sqrt{s^2+s^2} \\28\sqrt{2} =s\sqrt{2} \\[/tex]

Answer:

The projected cost of a gallon of oil by next june is $19.60.

Step-by-step explanation:

Given:

Oil prices are projected to increase by 100% by next june.

A quart of oil currently costs $2.45.

Now, to find the cost of a gallon of oil next june.

So, to get the projected cost of a quart of oil by next june:

Cost of one quart of oil currently = $2.45.

Rate of oil prices projected to increase by = 100%.

[tex]100\%\ of\ \$2.45+\$2.45\\\\=\frac{100}{100}\times 2.45+2.45\\\\=2.45+2.45\\\\=\$4.90.[/tex]

Now, to get the projected cost of a gallon of oil by next june we use conversion factor:

4 quart = 1 gallon.

If, 1 quart oil price = $4.90.

Then, 4 quarts oil price = [tex]\$4.90\times 4[/tex] = [tex]\$19.60.[/tex]

Thus, 1 gallon oil price = $19.60.

Therefore, the projected cost of a gallon of oil by next june is $19.60.

The mathematics question involves proving two triangles congruent in geometry, likely using congruence criteria such as SSS, SAS, or ASA, with the given information that line QR is parallel to PT.

The subject of this question is Mathematics, specifically it involves geometry and the proof of congruent triangles. The statement 'QR I PT' suggests that line QR is parallel to line PT. To prove triangles APQR and ATSR are congruent, one would need to demonstrate that they satisfy the criteria for congruence such as side-side-side (SSS), side-angle-side (SAS), or angle-side-angle (ASA). The angles mentioned, such as ∠QPR and ∠QRP, are likely parts of the required congruence criteria. However, additional information and a specific criteria of congruence need to be applied in a step-by-step explanation.

common factor= adding by 2

2n+3

find the 30th term

2×30+3=63

answer= 63

The 30th term of the linear sequence −5, −7, −9, −11, −13, . . . is -63. This is found using the formula for the nth term of a linear sequence, which is expressed as nth term = first term + (n - 1)*common difference.

The 30th term of a linear sequence can be found using the formula: nth term = first term + (n - 1)*common difference. In this sequence, the first term is -5 and the common difference (distance between each term) is -2 (since -7 minus -5 equals -2).

By substituting the appropriate values into the formula, we get: 30th term = -5 + (30 - 1)*(-2) = -5 - 58 = -63. Therefore, the 30th term of the sequence is -63.

- 5x - 1 = 19 ( add 1 to both sides )

- 5x = 20 ( divide both sides by - 5 )

Answer:

∠ b = 132°

Step-by-step explanation:

Since v and w are parallel.

The angle vertically opposite 48° is congruent , thus = 48°

b and 48° are same- side interior angles and supplementary, thus

b = 180° - 48° = 132°

Answer:

93.76%

Step-by-step explanation:

93.76% should be your new grade

I'm not 100% sure but what I did is that I divided each percent you have by it's worth. So for example, 96% x 20% = 0.192

I did this with all the possible percents and then I made them into whole number. So the 0.192 became 192. Here I divided it by 5. I should've divided by 4 but since the project is a 0% I didn't have to add it, just use it to divide.

So here I had 117.2 then I multiplied it by 80% because that's the total percent all those grades equaled and got 93.76%

Answer:

8π units²

Step-by-step explanation:

Area of the circle can be defined as pi 'π' times  the radius squared 'r²'

A= πr²

radius given is 4 (see attachment for the figure)

r=4

A = π4²

A= 16π

Now, if you look at the figure, you can see that the shaded area of the circle is 'half' of the whole circle.

We will half the Area which we have found it above in order to determine the area of shaded sector

Therefore,

area of the shaded sector =  16π/2 => 8π units²

Answer:

No

Step-by-step explanation:

No, the given list does not represent a complete probability model because the sum of the probabilities is not equal to 1.

The sum of probabilities should always equal to 1 in a complete probability model. In this case, the sum of probabilities is 16 + 13 + 112 + 12 = 153, which is not equal to 1. Therefore, it is not a complete probability model.

Final answer:

The provided list does not form a complete probability model because the probabilities do not sum up to 1, and some values exceed 1, which is not possible for probabilities.

Explanation:

The list provided does not represent a complete probability model because the probabilities of all possible outcomes of a probability model must sum up to 1. However, the sum of the probabilities listed (P(red) = 16, P(yellow) = 13, P(blue) = 1/12, and P(green) = 1/2) does not equal 1. The values for P(red) and P(yellow) seem to be mistakes or typos, as probabilities cannot be greater than 1. If these values were supposed to represent fractions and perhaps there are typos, they may need correcting to ensure the probabilities would sum up to 1. An example of a complete probability model can be seen in the jelly bean question mentioned, where the probabilities of selecting each color are fractions that sum up to 1.

Answer: OPTION 1

Step-by-step explanation:

For this exercise you need to remember that, by definition, the Arc length can be calculated with the following formula:

[tex]arc\ length=rC[/tex]

where "C" is the central angle of the arc in radians and "r" is the radius.

Since you need to find the Central  angle, you have to solve for "C" from that formula, as following:

[tex]C=\frac{arc\ length}{r}[/tex]

According to the information given in the exercise, you can identify that:

[tex]arc\ length=100\ m\\\\r=60\ m[/tex]

Therefore, the final step is to substitute these values into the formula and evaluate, in order to find the value of "C":

[tex]C=\frac{100\ m}{60\ m} \\\\C=\frac{5}{3}\ rad[/tex]
