The answer is <span>C.) 2
The general form of formula is
y = a </span><span>• r^x
y - the total number of bacteria after x period of time
a - the initial number of bacteria
r - growth rate
x - period of time
Let's compare:
</span>y = a • r^x
<span>y = 280 • 2^x
Since r = 2, the growth rate is C.) 2</span>
Quotient means division, which is obvious by all the division answers.
It says "Quotient of 4 AND ..." which means that four will be on top and everything else will be on the bottom.
So now you have:
four over something unknown.
Reading the rest of the question, "the sum of a number and three"
Sum means addition, again obvious by the answer choices.
"a number" is an unknown, so we can set that to x
and this x is being added to by three, so therefore
x+3 would be in your denominator.
You final equation should look like this:;
OR answer choice
A
Answer:
a) probability that neither is Tay-Sachs carrier is 0.9298
b) the probability that both are carriers is 0.001276
Step-by-step explanation:
Given that;
1 in 28 people of Ashkenazi jewish descent are Tay-Sachs carrier.
so P(Carrier) = 1/28 =
also P( Not a carrier) = 1 - 1/28 = 0.9643
Now After Sampling 1 man and 1 woman from the population;
a)
the probability neither is Tay-Sachs carrier
P( Neither is a Carrier) = 27/28 × 27/28 = 0.9298
Therefore probability that neither is Tay-Sachs carrier is 0.9298
b)
the probability both are carriers
P( Both are Carriers) = 1/28 × 1/28 = 0.001276
Therefore the probability that both are carriers is 0.001276
Answer:
33%
Step-by-step explanation:
total number of thimbles are 30 and only 10 of those are pink, so divide 10 by 30
