Answer:

There is a [tex]\frac{2}{21}[/tex] chance of picking caramel-filled chocolate.

Step-by-step explanation:

To set this up, you need to make it a fraction. The denominator of the fraction is how many total chocolates you can pick from. You can figure this out by adding all of the chocolate choices together:

68 hazelnut + 8 caramel + 8 orange = 84 chocolates.

The numerator is defined by the number of caramel chocolates, in this case it is 8. That means the fraction will look like:

[tex]\frac{8}{84}[/tex]

Now that can be simplified down. I divided the top and bottom both by 4 to get  [tex]\frac{2}{21}[/tex] and that is as far down as it can go. Therefore that is the probability you will get a caramel-filled chocolate.

Based on the z-score calculations, score A with a score of X = 55 should lead to the better grade.(option-a)

For score A with X = 55, the z-score can be calculated as:

z = (X - mean) / SD = (55 - 60) / 5 = -1

For score B with X = 40, the z-score can be calculated as:

z = (X - mean) / SD = (40 - 50) / 20 = -0.5

The z-score represents the number of standard deviations that a score is above or below the mean. A negative z-score means that the score is below the mean.

Since a z-score of -1 is greater than a z-score of -0.5, score A with X = 55 would be the better score. This is because score A is closer to the mean (60) than score B (50), and it has a smaller standard deviation (5) than score B (20). The lower standard deviation means that scores are more tightly clustered around the mean, making it more difficult to obtain a score that is much higher or lower than the mean.(option-a)

Answer:

m(x) = -2(x - 3)(x - 9)

One of the zeros of the function is x = 3

Step-by-step explanation:

The form that most quickly reveals the zeros (or "roots") of the function is:

m(x) = -2(x - 3)(x - 9)

To find the zeros of the function, we set m(x) equal to zero:

-2(x - 3)(x - 9) = 0

From this equation, we can see that the zeros (roots) of the function occur when either (x - 3) equals zero or (x - 9) equals zero. Solving these equations gives us the zeros:

x - 3 = 0

x = 3

x - 9 = 0

x = 9

Therefore, one of the zeros of the function is x = 3.

Hope this helps!

Answer:

See below.

Step-by-step explanation:

7x^2 = 343                     Divide both sides by 7

7x^2/7 = 343/7

x^2 = 49                         Take the square root of both sides.

sqrt(x^2) = sqrt(49)

x = +/- 7

I think the last two are kind of iffy. I'm not sure you can call them solutions, but the question probably assumes they are. If you use all four answers and get it wrong, them submit +7 and - 7.

Answer:

5/36

Step-by-step explanation:

Probability is the outcome that a  event will occur

Probability = Expected outcome/Total outcome

Since two sided dice are rolled, the total outcome will be expressed as;

Total outcome = 36

Since we are to find the probability that the sum is 8, the values that gives a sum of 8a re;

(2,6)(6,2), (5, 3), (3,5), (4, 4)

The expected outcome = 5

Probability = 5/36

Hence the probability that the sum is 8 is 5/36

Answer:

lallalalaal hiiiiii

Step-by-step explanation:

The standard form is written as y = ax ^2 + b + c

Using the given equation:

A = -5, b = 30 and c = 7

The x value of the vertex = -b/ 2/a = -30/2(-5) = -30/-10 = 3

To find the y value replace x with the x value and solve for y:

Y = -5(3)^2 + 30(3) + 7

Y = -45 + 90 + 7

Y = 52

The vertex is (3,52)

The answer is G
