Irene knows her blood type is A, but William does not know his blood type. However, William knows that his mother and father bot

Lostsunrise [7]

Based on this information, William's blood type could be either B or O.

What is Segregation of alleles?

Allele pairs (several features of the same gene) are segregated during meiosis so that they can be transferred selectively to different gametes.
During meiosis, maternal and paternal alleles separate.

What is genotype vs phenotype ?

Genotype: An organism's genetic makeup.
Phenotype. physical characteristic that arises within an organism as a result of its genotype. Probability law.
Genotype - the set of alleles that make up an organism.

How does genotype influence phenotype ?

The alleles you have for a specific gene or collection of genes are referred to as your genotype.

The physical attribute itself, or phenotype, can be affected by both genotype and environmental variables.

Transform the equation 3x + y = 5 into slope-intercept form.

marin [14]

Answer: y=-3x+5

Step-by-step explanation:

Slope-intercept form is y=mx+b. So to make your equation into slope-intercept form, simply subtract 3x from both sides, which results in y=-3x+5

What's the slope and y-intercept of the equation 3x + 4y = 8?

Anna71 [15]

Answer:

Slope = -3/4

y-intercept = 2

Step-by-step explanation:

$3x+4y = 8\\\therefore 4y = -3x +8\\\therefore y = \frac{-3}{4}x+ \frac{8}{4}\\\therefore y = \frac{-3}{4}x+2\\Equating \: it \: with\: \\y=mx+b\\Slope\:(m) = \frac{-3}{4}\\y-intercept\:(b) = 2$

Based on historical data, your manager believes that 37% of the company's orders come from first-time customers. A random sample

Answer:

0.6214 = 62.14% probability that the sample proportion is between 0.26 and 0.38

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 $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

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 estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

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

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$
