Answer: Her measuring cup has 8.25 mL of medicine.
Step-by-step explanation:
As per given,
In 11 mL of medicine, there are 20 drops.
That means quantity in 1 drop = mL
Now , the quantity in 15 drops = 15 x quantity in 1 drop
=
= 8.25 mL
Hence, her measuring cup has 8.25 mL of medicine.
Answer:
The approximate probability that a randomly selected aspen tree in this park in 1975 would have a diameter less than 5.5 inches = 0.15866
Step-by-step explanation:
The complete question is presented in the attached image to this answer.
It is stated that the distribution of tree diameters is approximately normal, hence, this is a normal distribution problem with
Mean diameter = μ = 8 inches
Standard deviation = σ = 2.5 inches
The approximate probability that a randomly selected aspen tree in this park in 1975 would have a diameter less than 5.5 inches = P(x < 5.5)
To solve this, we first normalize or standardize 5.5 inches
The standardized score for 45mg/L is the value minus the mean then divided by the standard deviation.
z = (x - μ)/σ = (5.5 - 8)/2.5 = - 1.00
The required probability
P(x < 5.5) = P(z < -1.00)
We'll use data from the normal probability table for these probabilities
P(x < 5.5) = P(z < -1.00) = 0.15866
Hope this Helps!!!
The function is 
.
The domain can only contain those values of x for which the denominator is not zero, that is all real numbers except 1,
AND for which 2-x i greater or equal to 0 (because if 2-x is negative, the square root of it cannot be calculated).
The last inequation,
, is solved as follows:
adding -2 to both sides we have
.
Multiplying by -1 (and not forgetting to swap the sign), we have
.
So x must be smaller or equal than 2, but also x cannot be 1, from the first condition. This means that the answer is <span>( - ∞ , 1 ) U ( 1 , 2].
