A jar contains 26 fluid ouncesbof spaghetti sauce. How many cups of spaghetti sauce do 4 jars contain

JulijaS [17]

____________________________________________________

Answer:

Your answer would be 13 cups of spaghetti sauce.

____________________________________________________

Explanation:

Lets break down this question to make the answer easier:

8 ounces = 1 cup

We are going to use the above to help us solve this question.

In your question, you have 26 ounces, and you would have four cups. You would need to calculate how many ounces are in the 4 cups

To do this, you would multiply 26 by 4:

26 × 4 = 104

The four cups have a total of 104 for ounces. But, you are not done solving yet. You need to found how many cups there are. We would be going to use the 8 ounces, since we know that is the amount of one cup, and use that to divide 104, since we need to distribute the amount of ounces to the cups.

You would divide 104 by 8

104 ÷ 8 = 13

There would be 13 cups of spaghetti sauce in 4 jars of spaghetti sauce that has 26 ounches in it.

Your FINAL answer would be 13.

A population of 100 tigers has 30 with horizontal stripes. Using pedigrees, you ascertain that horizontal striping is caused by

bixtya [17]

Assuming that this population is in Hardy-Weinberg equilibrium, we can sayt that the probability that, given enough time, all tigers in the population will have horizontal stripes is 30% = 0.3.

--------------------------

Available data:

Population size, N = 100 tigers
Number of Tigers with horizontal stripes = 30
Horizontal stripes is caused by an autosomal recessive mutation.

We need to know the probability that all tigers in the population will have horizontal stripes, which is the recessive phenotype.

We assume that the population is in Hardy-Weinberg equilibrium, so there should be no evolution.

Since the population is in H-W equilibrium, the allelic, genotypic and phenotypic frequencies will remain the same generation after generation.

Now, we will calculate the allelic and genotypic frequencies of horizontal striped individuals in the population.

There are 100 individuals, and only 30 have horizontal stripes.

So, the phenotypic frequency, F(HS) is 30/100 = 0.3 = 30%

Since this is a recessive phenotype, this value equals the genotypic frequency, F(hh) = 30%

Finally, we can get the allelic frequency by taking the square root of this value.

F(hh) = q² = 0.3

f(h) = q = √0.3 = 0.55 = 55%

According to these calcs, the probability for the fixation of the recessive allele is 55%, and the probability that all individuals express the recessive horizontal stripes phenotype is 30%.
