The approximate angle between the vectors named U and V with their magnitudes and dot product is gotten as; 91°
What is the angle between the vectors?We are given;
Magnitude of Vector U; |U| = 34
Magnitude of vector V; |V| = 20
Dot Product of u and v; U.V = -10
Formula for angle between vectors is;
θ = cos⁻¹[(U.V)/|U| * |V|]
θ = cos⁻¹(-10/(34 * 20))
θ = cos⁻¹-0.0135
θ ≈ 91°

The pythagorean theorem is used to calculate the lengths of a right triangle
The hypotenuse of the triangle is 6.5 cm
How to determine the hypotenuse of the triangle?From the complete question, we have the following side lengths
Opposite = 5.7 cmAdjacent = 3.2 cmThe hypotenuse of the triangle is then calculated as:
Hypotenuse^2 = Opposite^2 + Adjacent^2
This gives
Hypotenuse^2 = 3.2^2 + 5.7^2
Evaluate the sum
Hypotenuse^2 = 42.73
Take the square root of both sides
Hypotenuse = 6.5
Hence, the hypotenuse of the triangle is 6.5 cm

Calculate the number of moles contained in 550. ml of carbon dioxide at stp.
Considering the definition of STP conditions, 0.02455 moles are contained in 550 mL of carbon dioxide at STP.
Definition of STP conditionThe STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.
Amount of moles contained in 550 mLIn this case, you can apply the following rule of three: if by definition of STP conditions 22.4 liters are occupied by 1 mole of helium, 0.550 L (0.550 L= 550 mL, being 1 L= 1000 mL) are occupied by how many moles?
[tex]amount of moles=\frac{0.550 Lx 1 mole}{22.4 L}[/tex]
amount of moles= 0.02455 moles
Finally, 0.02455 moles are contained in 550 mL of carbon dioxide at STP.

Intensive care units (icus) generally treat the sickest patients in a hospital. icus are often the most expensive department in a hospital because of the specialized equipment and extensive training required to be an icu doctor or nurse. therefore, it is important to use icus as efficiently as possible in a hospital. according to a large-scale study of elderly icu patients, the average length of stay in the icu is days (critical care medicine journal article). assume that this length of stay in the icu has an exponential distribution. do not round intermediate calculations.
a. Probability that the length of stay in the ICU is one day or less is:0.2614.
b. Probability that the length of stay in the ICU is between two and three days is:0.1426
c. Probability that the length of stay in the ICU is more than five days is:0.2198.
Probability
a. Probabilty of one day or less.
Using this formula
P(X≤1)=1-e^-ux
Since mean is 3.3 the decay parameter is:
u=1/3.3
Hence:
P(X≤1)=1-e^-1/3.3
P(X≤1)=1-e^-0.3030
P(X≤1)=1-0.7385991
P(X≤1)=0.2614
b. Probability of two and three days.
P(X≤2)=1-e^-ux
P(X≤2)=1-e^-2/3.3
P(X≤2)=1-e^-0.60606
P(X≤2)=1-0.54549589
P(X≤2)=0.45450
P(X≤3)=1-e^-ux
P(X≤3)=1-e^-3/3.3
P(X≤3)=1-e^-0.909091
P(X≤3)=1-0.402890
P(X≤3)=0.59711
Hence:
P(2≤X≤3)=0.59711-0.45450
P(2≤X≤3)=0.1426
c. Probability of more than 5 days.
P(X≤5)=e^-ux
P(X≤5)=e^-5/3.3
P(X≤5)=e^-1.515152
P(X≤5)=0.219775
P(X≤5)=0.2198 (Approximately)
