Answer:

y = 2x + 11

Step-by-step explanation:

The general equation for the slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

We know that the y-intercept occurs when x is 0 so it's already given and is (0, 11).

We can find the slope using the slope formula:

\(m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} } \\m=\frac{19-11}{4-0}\\ m=\frac{8}{4}=2\)

The possible noon temperatures are 33° F and 13° F.

Temperature is a degree of hotness or coldness the can be measured using a thermometer. It's also a measure of how fast the atoms and molecules of a substance are moving. Temperature is measured in degrees on the Fahrenheit, Celsius, and Kelvin scales.

Given that, the temperature is 23 degrees F, at sunrise. By noon, the temperature changes by 10 degrees F.

Let x° F be the temperature at noon.

Here, temperature at noon is

x= 23+10=33° F and x= 23-10=13° F

Therefore, the possible noon temperatures are 33° F and 13° F.

Answer:

\(\huge\boxed{\sf x =\frac{7}{2} , y = -3}\)

Step-by-step explanation:

2x + 4y = -4 ------------------------(1)

3x + 5y = -3 ------------------------(2)

Multiply Eq. (1) by 3

3(2x + 4y) = -4 * 3

6x + 12y = -12 ---------------------(3)

Multiply Eq. (2) by 2

2(3x + 5y) = -3 * 2

6x + 10y = -6 ---------------------(4)

Subtract Eq. (4) from (3)

6x + 12y - ( 6x + 10y ) = -12 - (-6)

6x + 12y - 6x - 10y = -12 + 6

12y - 10y = -6

2y = -6

Divide 2 to both sides

y = -6 / 2

y = -3

Put y = -3 in Eq. (1)

2x + 4(-3) = -5

2x - 12 = -5

Add 12 to both sides

2x = -5 + 12

2x = 7

Divide 2 to both sides

x = 7 / 2

So,

x = 7 / 2 , y = -3

The type of sampling described, where the researchers intentionally select a sample with 50% straight and 50% LGBTQ+ respondents, is known as "disproportionate stratified sampling."

A. Disproportionate stratified sampling involves dividing the population into different groups (strata) based on certain characteristics and then intentionally selecting a different proportion of individuals from each group. In this case, the researchers are dividing the population based on sexual orientation (straight and LGBTQ+) and selecting an equal proportion from each group.

B. Availability sampling (also known as convenience sampling) refers to selecting individuals who are readily available or convenient for the researcher. This type of sampling does not guarantee representative or unbiased results and may introduce bias into the study.

C. Snowball sampling involves starting with a small number of participants who meet certain criteria and then asking them to refer other potential participants who also meet the criteria. This sampling method is often used when the target population is difficult to reach or identify, such as in hidden or marginalized communities.

D. Simple random sampling involves randomly selecting individuals from the population without any specific stratification or deliberate imbalance. Each individual in the population has an equal chance of being selected.

Given the description provided, the sampling method of intentionally selecting 50% straight and 50% LGBTQ+ respondents represents disproportionate stratified sampling.

Answer: the neutral rho meson has a longer life span because it has 1.5x more than the other one

Step-by-step explanation:

The percentage of lids that are too small or too big can be determined by calculating the respective probabilities using z-scores.

(a) To find the percentage of large lids that are too small to fit, we need to calculate the probability that a lid has a diameter less than 3.95 inches. First, we calculate the z-score for a diameter of 3.95 inches using the formula:

z = (x - μ) / σ

where x is the given diameter, μ is the mean, and σ is the standard deviation. Plugging in the values:

z = (3.95 - 3.98) / 0.02 = -1.5

Using a standard normal distribution table or statistical software, we can find the corresponding probability, which represents the percentage of lids that are too small.

(b) Similarly, to find the percentage of large lids that are too big to fit, we calculate the probability that a lid has a diameter greater than 4.05 inches. Using the same z-score formula, we find the z-score for a diameter of 4.05 inches:

z = (4.05 - 3.98) / 0.02 = 3.5

Again, using a standard normal distribution table or statistical software, we determine the corresponding probability.

Comparing the answers from (a) and (b), we can observe whether one percentage is larger than the other. If the percentage of lids that are too small is significantly larger, it would make sense for the lid manufacturer to increase the values to prevent lids from being too small. Conversely, if the percentage of lids that are too big is significantly larger, the manufacturer should consider reducing the values to avoid lids being too large. The comparison provides insight into the adjustments the manufacturer may need to make to ensure a better fit for the lids on the large drink cups.

For completion of maze faster, time need to be decreased. therefore test is left tailed.

The significance level, also denoted as alpha or α, is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference.

These types of definitions can be hard to understand because of their technical nature. A picture makes the concepts much easier to comprehend!

The significance level determines how far out from the null hypothesis value we'll draw that line on the graph. To graph a significance level of 0.05, we need to shade the 5% of the distribution that is furthest away from the null hypothesis.

according to the sum of the exterior angles of  a polygon, we get that the exterior angles of this polygon add up to 360

so our equation is: 9x-31+7x-2+4x+33=360,

the -31-2+33 cancel out,

and combining like terms gives us: 20x=360

so x=18,

Answer:

the sale price of the flip flops after tax is $12.87.

Step-by-step explanation:

To calculate the sale price of the flip flops after tax, we need to consider both the discount and the sales tax. Here's how we can calculate it:Calculate the discounted price:

The flip flops cost $15, and there is a 20% discount. To find the discounted price, we subtract the discount amount from the original price:

Discounted price = $15 - (20% of $15)

To calculate the discount amount, we multiply the original price by the discount percentage (expressed as a decimal):

Discount amount = 20% of $15 = 0.20 * $15Discounted price = $15 - (0.20 * $15)Calculate the sale price after tax:

After applying the discount, we need to calculate the sales tax on the discounted price. To do this, we add the sales tax amount to the discounted price:

Sale price after tax = Discounted price + (7.25% of Discounted price)

To calculate the sales tax amount, we multiply the discounted price by the sales tax percentage (expressed as a decimal):

Sales tax amount = 7.25% of Discounted price = 0.0725 * Discounted priceSale price after tax = Discounted price + (0.0725 * Discounted price)Now, let's substitute the values and calculate:Discounted price = $15 - (0.20 * $15) = $15 - ($3) = $12Sale price after tax = $12 + (0.0725 * $12) = $12 + $0.87 = $12.87
