The specific gravity of Hg is 13.6. So to translate the -10 mm Hg to water, we multiply -10mm by the specific of Hg to get -10mm*13.6= -136mm water.
if ur reading this ur hella dumb useless person
Second line in example should read: 8(other numerator) * 6 (this denominator) = 48
Another way is to cross multiply. Multiply one numerator by the denominator of the other. Repeat for the other numerator. If the products are equal, they're in proportion. Example: 4/6 : 8/12 4(numerator) * 12 (other denominator) = 48 8(other numerator) *
Comparing families 1 and 2 allows us to make a hypothesis that it is a case of dominant/recessive, which can be confirmed with families three and four. Feel free to propose a scenario for discussion.
The meninges consists of three layers, dura mata, arachnoid mater and pia mater (innermost). Together, the layers fulfull all four functions of protecting the nervous system from traumas by filling the space with cerebrospinal fluids. Blood vessels and
The spinal accessory has long been considered cranial #11 (out of 12). Lately there have been debates on this though.
Regarding : "but didn't feel like typing that much work." I consider a proper answer related to Punnett squares should indicate the genotypes and interpret them in terms of phenotypes, whether asked for explicitly or not. Again, I consider that as a part
To Nameless: In case you have not yet verified, the fourth one should read y = -(x-3)^2 + 5 in order to have the vertex at (3,5). Suggest you post your attempt for the fifth.
I guess it is part of the exercise to test knowledge of the well-known sex-linked traits.
continued: (where Xx is the carrier mother, xy is the normal father) Outcomes (each 25%) Xx = daughter is a carrier xx = daughter is free from hemophilia Xy = son had hemophelia xy = son is free from hemophelia
To answre this question, we need to know a few facts about hemophilia. It is an X-linked recessive defect, which means that it is present only on the x-chromosome, and in females, which has 2 x-chromosomes, will require both copies to be defective to have
Please describe what you see in the figure, because we don't.

See response to previous question.
Since it is a monopolistic product, it will be assumed everything made will be sold, and at the predicted price. p = selling price Quantity sold=quantity manufactured = q(p) =60-p/2 Cost, C = 60 at all sales volumes Profit in terms of price, p P(p)=
Assuming the worst case of the point estimate of 50% (i.e. 50% participation), and n=size of sample Margin of error = z1-α * standard error of worst case point estimate = z95% * sqrt(0.5(1-0.5)/n) =1.96 * 0.5/sqrt(n) Equate to given margin of error of
Using the definition of logarithms y=loga(x) .......(1a) ≡ ay = x .............(1b) Put x=11 in (1a), log(x) is understood to be base 10, so a=10, y=1.0414 [1a] 1.0414 = log10(11) By the definition of logarithms, (1a) is equivalent to (1b), so
Assuming you mean: Given that loga(7) = 0.845, and loga(2) = 0.301, find loga(343). Using the rule of logarithm: loga(xn) = n*loga(x) .............(1) From 7^3=343, we substitute in (1) x=7, n=3, so loga(343) =loga(73) = 3*loga(7) = 3*0.845 = ?
Is the question actually (note punctuation and parentheses) the following? if n varies inversely as kv/(k+v), and n is equal to 16 when k=4 v=8, find the relationship between k v and n.
One of the rules of logarithm is log(a)+log(b) = log(ab)........................(1) This means that the logarithm of a product is the sum of the logarithms of the multiplicant and multiplier. Since 4x is a product of 4 * x Which do you think is the right
10% gives $889 after one year. 15% gives $8890*0.15=$1333.5 after one year. So the annual interest is a minimum of $889. If only $560 was earned after one year, someone got short-changed, sorry to say.
Given equation: (x+1/x)² - 14(x+1/x) = 72 ...............(1) Use the substitution u=x+1/x .............................................................................(1a) then (1) becomes u² - 14u -72 = 0 .....................................(2) Factor
In human diploid cells, there are 23 homologous sets of two chromosomes (=46). Each chromosome is composed of one DNA molecule. In the replication stage, each chomosome is duplicated into two chromatids (two DNA molecules), but are still attached by the
Given: purchase price = 320,000 down payment = 8% mortgage bought down (to 6%) with 3 points (3%). Term, n= 30 years rate, i=6% per annum = 6%/12 = 0.005 compounding frequency = monthly (ASSUMED). Solution: Down payment = 8% * 320,000 = 25,600 Loan, P =

We don't need the website. translation 3 units right and 2 units down follows the following rule: (x,y)->(x+3,y-2) So we will need to take the coordinates of A, B and C, and transform each point according to the rule given above. For example, if P(2,5),
1) After giving $5 to Greg, David has $25. Greg now has 1/5 as much as Davis does. How much did Greg start with? Now David has $25 Greg now has 1/5 of David, or 1/5 of 25, or 5. So before he got $5 from David, Greg had 5-5=0, or nothing. 2) if
p+pq = 4(p-pq) p(1+q) = 4p(1-q) Since pq ≠ 0, then we can cancel out p on both sides. => 1+q=4(1-q) Expand and solve for q 1+q=4-4q 5q=4-1=3 q=3/5 Check: (1+q)=1+3/5=8/5 4(1-q)=4(1-3/5)=4(2/5)=8/5 Therefore the value of q is correct and unique.

Here's an example of what the question is asking for: If Molly removed 2 orange marbles, the probability of drawing an orange marble from the remaining batch is P(Orange) = (2-2)/(4+3+3+0) = 0/10 = 0 and that does not equal 1/5, so she did not remove 2
Twenty members of a group contributed sh 80000 each means contribution from members = 20 members * 80000 =sh 1600000 They already had sh 120000 in a bank out of which sh 20000 was to remain means from bank reserve = 120000 - 20000 = sh 100000 Price of land
Well, I do not know how you got the range as ± 3 to ± 11.1. The interpretation of your answer is -11.1 (excluding) to -3 (including) together with 3 (including) to 11.1 (excluding). This means that (-3,3) is excluded from the range. Confirm that this
The man has Widow's peak (Ww or WW) and attached earlobes (dd), and the woman without widow's peak (ww) and detached earlobes (Dd, the d is inherited from her father). So yes, Man: Wwdd or WWdd (could be either one) Woman: wwDd. Case 1: If man has Wwdd
The fact that fur colour can be tortoise means that both phenotypes are expressed, as a result of codominance of the genotypes black and orange. Since we are given that fur colour is controlled by X-linked alleles, it means that tortoise can only be
