Answer:
\(\frac{3}{4}\)
Step-by-step explanation:
y = mx + b , "m" is slope and "b" is y-intercept
~~~~~~~~~~~~~
3x - 4y = 7
- 4y = - 3x + 7
y = \(\frac{3}{4}\) x - \(\frac{7}{4}\) ⇒ m = \(\frac{3}{4}\)
recall that on the act math section, the scores are graded to follow the normal model with a mean of about 18.5 and a standard deviation of about 5.75. based on this model, what is the cutoff score to be in the bottom 6% of all act math scores?
The cutoff score to be in the bottom 6% of all ACT math scores is about 27.71. To find the cutoff score to be in the bottom 6% of all ACT math scores, we need to use the normal distribution table.
First, we need to convert the score to a z-score using the formula: z = (x - μ) / σ, where x is the score, μ is the mean, and σ is the standard deviation.
For the bottom 6% of scores, we need to find the z-score that corresponds to a cumulative probability of 0.06. Looking at the normal distribution table, we find that the closest value is 1.55.
So, we can solve for the score by rearranging the formula as x = z * σ + μ. Plugging in the values, we get:
x = 1.55 * 5.75 + 18.5 = 27.7125
It's important to note that this calculation is based on the assumption that the distribution of ACT math scores follows the normal model with a mean of about 18.5 and a standard deviation of about 5.75. In reality, the distribution may not be exactly normal, and the mean and standard deviation may vary depending on the sample of test takers.

A Sack contains 80 balls of which 25 and 40 are red and green respectively. The remaining balls are black. If a ball is selected at random, what is the probability that the ball is: (a) green (b) black (c) red (d) neither green nor black
Probability of choosing green balls = 1/22. Probability of choosing black balls = 3/163. Probability of choosing red balls = 5/164. Probability of choosing neither green nor black balls = 5/16.
The given data shows that the sack has 80 balls out of which 25 are red and 40 are green. The remaining balls will be black.Therefore, the number of black balls will be= Total number of balls - (Red balls + Green balls)= 80 - (25 + 40) = 15Part (a)If a ball is chosen randomly from the sack, then the probability that the ball chosen is green is given by:Probability of choosing green balls = Number of green balls/Total number of balls= 40/80= 1/2Part (b)If a ball is chosen randomly from the sack, then the probability that the ball chosen is black is given by:Probability of choosing black balls = Number of black balls/Total number of balls= 15/80= 3/16Part (c)If a ball is chosen randomly from the sack, then the probability that the ball chosen is red is given by:Probability of choosing red balls = Number of red balls/Total number of balls= 25/80= 5/16Part (d)Neither green nor black balls are red balls. Hence, the probability of choosing neither green nor black balls is the probability of choosing red balls. Therefore, the probability of choosing neither green nor black balls is 5/16.The probability of the following events are:1. Probability of choosing green balls = 1/22. Probability of choosing black balls = 3/163. Probability of choosing red balls = 5/164. Probability of choosing neither green nor black balls = 5/16.

Find the slope and the y-intercept of the equation below:
1. 4x-3y=12
2. 2y=6x-12
if you can put the step please do so. Tysm.
Answer + Explanation:
1. you want to rearrange the equation ( don't change the actual value ) to put it in the form y = mx + b. in this form, m represents the slope and b represents the y-intercept.
this is how you would do that:
4x - 3y = 12
subtract 4x from both sides
-3y = -4x + 12
divide both sides by -3
y = 4/3x - 4
this means the slope is 4/3 and the y-intercept is -4
2. do the same thing, rearranging into y = mx + b form
2y = 6x - 12
divide both sides by 2
y = 3x - 6
this means the slope is 3 and the y-intercept is -6
Determine if each statement is true or false. Justify your answer.
log₂4+log₂8=5
The statement \(log_{2} 4 + log_{2} 8 = 5\) is true.
We have been given two logarithm terms that is the first term is \(log_{2} 4\) and second term is \(log_{2} 8\).
The properties of logarithm that we are going to use are
\(log a^{m} = m *log a\) and \(log_{a} a = 1\)
First we will find the value of the two terms by operating the above mentioned properties of logarithm to obtained the values of the logarithm.
Thus,
\(log_{2} 4 = log_{2} 2^{2} \\ = 2* log_{2} 2\\ = 2*1\\ = 2\)
Similarly,
\(log_{2} 8 = log_{2} 2^{3} \\ = 3* log_{2} 2\\ = 3*1\\ = 3\)
Now adding both the terms by substituting its respective values which we have calculated above, we get
\(log_{2} 4 + log_{2} 8 = 2+3 = 5\)
Thus, we have proved that R.H.S = L.H.S
Hence the statement is \(log_{2} 4 + log_{2} 8 = 5\) is true.

Answer:
Equation: y = 3/4(x) + 1
Slope: 3/4

Step-by-step explanation:
1. How do we solve this problem?
To find the slope and y-intercept, we should first isolate the variable, y, on one side to make it easier to find.Step 1: Simplify both sides of the equation.
\((2x + x) = (4)(y) + (4)(-1)\) \(3x = 4y - 4\)Step 2: Flip the equation.
\(4y - 4 = 3x\)Step 3: Add 4 to both sides.
\(4y - 4 + 4 = 3x + 4\) \(4y = 3x + 4\)Step 4: Divide both sides by 4.
\(\frac{4y}{4} = \frac{3x+4}{4}\) \(y = \frac{3}{4}x + 1\)2. Now, the y-intercept form of an equation goes like this: y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept. In the place of m, the slope is 3/4. In the place of b, the y-intercept is 1.

5x+3y=-9 in slope intercept
The slope-intercept form of the equation 5x + 3y = -9 is y = (-5/3)x - 3.
To rewrite the equation 5x + 3y = -9 in slope-intercept form, which is in the form y = mx + b, where m represents the slope and b represents the y-intercept, we need to solve for y.
Let's start by isolating y:
5x + 3y = -9
Subtract 5x from both sides:
3y = -5x - 9
Divide both sides by 3 to isolate y:
y = (-5/3)x - 3
Now, we have the equation in slope-intercept form. The slope of the line is -5/3, which means that for every unit increase in x, y decreases by 5/3 units. The y-intercept is -3, which means that the line intersects the y-axis at the point (0, -3).
Therefore, the slope-intercept form of the equation 5x + 3y = -9 is y = (-5/3)x - 3.

i offer you a gamble in which you win $1200 if a card randomly drawn from a standard 52-card deck is red and you lose $1200 if the card is black. what is the expected value of the gamble?
The expected value of a gamble can be calculated by multiplying the probability of winning by the amount you could win and subtracting the probability of losing multiplied by the amount you could lose.
In this case, we are given that if a red card is drawn from a standard 52-card deck, you win $1200, and if a black card is drawn, you lose $1200.
First, let's determine the probability of drawing a red card from a standard 52-card deck. In a standard deck, there are 26 red cards (13 hearts and 13 diamonds) and 26 black cards (13 spades and 13 clubs). So the probability of drawing a red card is 26/52, which simplifies to 1/2 or 0.5.
Next, let's calculate the probability of losing, which is the probability of drawing a black card. Similarly, the probability of drawing a black card is also 26/52 or 1/2.
Now, we can calculate the expected value using the formula:
Expected value = (probability of winning * amount won) - (probability of losing * amount lost)
Expected value = (0.5 * $1200) - (0.5 * $1200)
Expected value = $600 - $600
Expected value = $0
Therefore, the expected value of the gamble is $0. This means that, on average, you neither win nor lose money in the long run by playing this gamble.
