3y + 4x = 12

To find the y intercept, set x =0 and solve for y

3y = 4*0 =12

3y = 12

Divide by 3

3y/3 = 12/3

y =4

Answer:

4

Step-by-step explanation:

3y + 4x = 12

3y = -4x + 12

y = -[tex]\frac{4}{3}[/tex]x + 4

Answer:

1 + 4x - 3 = 6x + 8

4x - 6x = 8 - 1 + 3

Step-by-step explanation:

The requried interval that represents the middle 95% of Shaquana's commute times is (16, 28) minutes

The empirical rule, also known as the three-sigma rule, is a statistical concept that provides a quick estimate of the spread of a normal distribution.

Since Shaquana's commute times are normally distributed with a mean of 22 minutes and a standard deviation of 3 minutes, we can use this information to find the interval that represents the middle 95% of her commute times.

To do this, we need to find the range of values that is two standard deviations away from the mean in either direction.

Lower limit = Mean - 2SD = 22 - 23 = 16 minutes

Upper limit = Mean + 2SD = 22 + 23 = 28 minutes

Therefore, the interval that represents the middle 95% of Shaquana's commute times is (16, 28) minutes. This means that we expect Shaquana's commute time to be between 16 and 28 minutes, with 95% confidence.

Answer:

here we have:

x = 5*t + 3

y = 2*t - 6

both for -2 ≤ t ≤ 3

First, we can rewrite:

x = a*y + b

let's try to find the values of a and b.

5*t + 3 = a*(2*t - 6) + b

5*t + 3 = a*2*t + (b - 6*a)

Here we have two equations:

5 = a*2

3 = (b - 6*a)

from the first one, we can solve:

5/2 = a

replacing this into the second, we et:

3 = b - 6*(5/2)

3 = b - 15

3 + 15 = b = 18

Then:

x = (5/2)*y + 18

y =  2*t - 6

So, y is a linear equation that depends on the variable t

x is a linear equation that only depends on x (from this we already know that the graph will be a line)

and we know that  −2 ≤ t ≤ 3

Then the minimum value of y is:

y = 2*(-2) - 6 = -10

and the largest value of y is:

y = 2*3 - 6 = 0

So y-varies in the range between -10 and 0

And because x =  (5/2)*y + 18

The minimum value of x is:

x = (5/2)*-10 + 18 = -25 + 18 = -7

and the maximum value of x is:

x = (5/2)*0 + 18 = 18

Then we know that this line starts in the point (-10, -7) and ends in the point (0, 18)

  s = √(75 ft²) = √(25·3 ft²) = √(3·(5 ft)²)

  s = 5√3 ft ≈ 8.7 ft . . . . . . side length of garden

Step-by-step explanation:

When a number is in front of the parethese, it is multiplying all the terms inside of it.

Looking at the first answer, the 2 multiplies 2/5x and 2, getting 4/5x + 4. This is not equivllent to 2 2/5x +1.

In the next one 2 is multiplying the same values, and results in 4/5x + 4. This is indeed equivelent to 4/5x + 4.

So this is your answer.

Answer:

0.0808 = 8.08% probability that the mean battery life would be greater than 526.4 minutes

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

The design engineer claims they have a variance of 2916 with a mean life of 518 minutes.

This means that [tex]\sigma = \sqrt{2916} = 54, \mu = 518[/tex]

Sample of 81 batteries

This means that [tex]n = 81, s = \frac{54}{\sqrt{81}} = 6[/tex]

What is the probability that the mean battery life would be greater than 526.4 minutes?

1 subtracted by the p-value of Z when X = 526.4. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{526.4 - 518}{6}[/tex]

[tex]Z = 1.4[/tex]

[tex]Z = 1.4[/tex] has a p-value of 0.9192

1 - 0.9192 = 0.0808

0.0808 = 8.08% probability that the mean battery life would be greater than 526.4 minutes
