Answer:
a- independent x
dependant = y
An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure.
The dependent variable is the one that depends on the value of some other number. If, say, y = x+3, then the value y can have depends on what the value of x is.
b)
slope = (y2-y1) / (x2-x1)

y = 3x +b

You deposit $600 in an account that earns simple interest. The difference between the total interest earned after 8 years and the total interest earned after 5 years is $108. What is the annual interest rate?
Answers
The annual interest rate is approximately 0.06 or 6%.
To solve this problem, we can use the formula for simple interest.
Interest = Principal * Rate * Time
Let's denote the annual interest rate as "r."
After 8 years, the total interest earned is given by:
Interest after 8 years = Principal * Rate * Time
= $600 * r * 8
= $4800r
After 5 years, the total interest earned is given by:
Interest after 5 years = Principal * Rate * Time
= $600 * r * 5
= $3000r
According to the given information, the difference between the total interest earned after 8 years and the total interest earned after 5 years is $108:
Interest after 8 years - Interest after 5 years = $4800r - $3000r = $108
Simplifying the equation:
$1800r = $108
Now, we can solve for the annual interest rate "r":
r = $108 / $1800
r ≈ 0.06
The annual interest rate is approximately 0.06 or 6%.
Therefore, the annual interest rate is 6%.

Answers
In order to find the quadratic equation, let's use the vertex form below:
\(y=a(x-h)^2+k\)Where the vertex is located at (h, k).
So, if the vertex is (h, k) = (-4, 2) and using the point (x, y) = (-4, 0), we have:
\(\begin{gathered} y=a(x+4)^2+2 \\ 0=a(-4+4)^2+2 \\ 0=a\cdot0^2+2 \\ 0=2 \end{gathered}\)Since the final statement is false, it's not possible to have a quadratic function with vertex (-4, 2) and with the point (-4, 0).
If we use the point (4, 0) instead, we would have:
\(\begin{gathered} y=a(x+4)^2+2 \\ 0=a(4+4)^2+2 \\ 0=a\cdot64+2 \\ 64a=-2 \\ a=-\frac{2}{64} \\ a=-\frac{1}{32} \end{gathered}\)So the equation in this case would be:
\(y=(-\frac{1}{32})(x-(-4))^2+2\)The empty spaces would be filled with the values -1/32, -4 and 2.

Summation ^ infinity _ n = 1 n^k-1/n^k+7, k > 2 n^k-1/n^k +7 lim n rightarrow infinity = l >0 converges diverges
Answers
For the first series, we can use the Limit Comparison Test by comparing it to the series 1/n^2. Specifically, we will take the limit as n approaches infinity of the quotient of the two series:
lim_n->∞ [(n + 7)/(n^3 - 3n + 3)] / (1/n^2)
= lim_n->∞ [(n + 7)/(n^3 - 3n + 3)] * (n^2/1)
= lim_n->∞ [(n^3 + 7n^2)/(n^3 - 3n + 3)]
Since the numerator and denominator both have degree 3, we can apply L'Hopital's rule:
= lim_n->∞ [(3n^2 + 14n)/(3n^2 - 3)]
= lim_n->∞ [3 + 14/n] / [3 - 3/n^2]
= 3/3 = 1
Since the limit is positive and finite, and the series 1/n^2 is known to converge, the original series also converges.
For the second series, we can use the Limit Comparison Test by comparing it to the series 1/n^2. Specifically, we will take the limit as n approaches infinity of the quotient of the two series:
lim_n->∞ [(n^(k-1))/(n^(k+7))] / (1/n^2)
= lim_n->∞ (n^(k-1) * n^2) / (n^(k+7))
= lim_n->∞ n^(k+1) / n^(k+7)
= lim_n->∞ 1/n^6
Since the limit is positive and finite, and the series 1/n^2 is known to converge, the original series also converges.

You roll a fair ten-faced die, numbered from one to ten, then ten you draw a card from a standard deck of 52 cards.
a) What is the size of the sample space?
b) Find P(A), A is the outcome in which you roll a 10 and then draw the Ace of spades.
c) Find the chances of you rolling a number smaller than 9 and then drawing the Ace of spades.
d) Find the chances of you rolling the number 10 and then drawing a card of spades.
e) Find the chances of you rolling a number smaller than 9 and then drawing a card of spades, or rolling anything and then drawing the ace of spades.
--------
Answers
a) The size of the sample space is the total number of possible outcomes. In this case, the sample space consists of rolling a ten-faced die and drawing a card from a standard deck, resulting in a sample space of 10 * 52 = 520 outcomes.
b) The probability of event A, which is rolling a 10 and then drawing the Ace of spades, can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
c) The probability of rolling a number smaller than 9 and then drawing the Ace of spades can be determined similarly.
a) Since there are 10 possible outcomes when rolling the die and 52 possible outcomes when drawing a card, the total number of outcomes in the sample space is 10 * 52 = 520.
b) To find the probability of event A, we need to determine the number of favorable outcomes. There is only one outcome where you roll a 10 and then draw the Ace of spades. Therefore, P(A) = 1/520.
c) The probability of rolling a number smaller than 9 and then drawing the Ace of spades depends on the favorable outcomes in the sample space. There are 8 possible outcomes when rolling a number smaller than 9, and only one favorable outcome when drawing the Ace of spades. So, P(rolling <9 and drawing Ace of spades) = (8/10) * (1/52) = 2/65.
d) The probability of rolling the number 10 and then drawing a card of spades is calculated in a similar manner. There is one favorable outcome for rolling a 10 and 13 favorable outcomes for drawing a spade. Thus, P(rolling 10 and drawing spade) = (1/10) * (13/52) = 1/40.
e) The probability of rolling a number smaller than 9 and then drawing a card of spades, or rolling anything and then drawing the Ace of spades, can be found by adding the probabilities of the individual events. P(rolling <9 and drawing spade or rolling anything and drawing Ace of spades) = (8/10 * 13/52) + (10/10 * 1/52) = 53/65.

What would most likely happen if a person skipped step 3? the eggs would be undercooked. the eggs would not be blended. the eggs would not be folded. the eggs would stick to the pan.
Answers
If a person skips step 3 of blending or whisking the eggs, the eggs are likely to stick to the pan during cooking techniques .
Skipping step 3 in a cooking process can result in the eggs sticking to the pan.
When preparing eggs, step 3 typically involves blending or whisking the eggs. This step is crucial as it helps to incorporate air into the eggs, creating a light and fluffy texture. Additionally, whisking the eggs thoroughly ensures that the yolks and whites are well mixed, resulting in a uniform consistency.
By skipping step 3 and not whisking or blending the eggs, they will not be properly mixed. This can lead to the yolks and whites remaining separated, resulting in an uneven distribution of ingredients. As a consequence, when cooking the eggs, they may stick to the pan due to the clumps of not blended yolks or whites.
Whisking or blending the eggs in step 3 is essential, as it introduces air and creates a homogenous mixture. The incorporation of air adds volume to the eggs, contributing to their light and fluffy texture when cooked. It also aids in the cooking process by allowing heat to distribute more evenly throughout the eggs.
To avoid the eggs sticking to the pan, it is important to follow step 3 and whisk or blend the eggs thoroughly before cooking. This ensures that the eggs are properly mixed, resulting in a smooth consistency and even cooking.
