At her archery lessons, Tess has a 90% chance of getting a bull's eye. Unfortunately, there is only a 40% chance that her

zepelin [54]

Answer:

Step-by-step explanation

2. you gave that there is a 40% chance that her instructor will be watching, which means that there is a 60% chance he will not be watching (100% - 40%).

3. you gave that there is a 90% chance of making a bull's eye, and 40% chance the instructor will be watching

since those two events are independent of each other, the chance of both of them happening is the product of the two chances, namely 0.9 x 0.4 = 0.36, or 36%

While John is traveling along a straight interstate highway, he notices that the mile marker reads 243 km. John travels until he

loris [4]

Answer:

The displacement is: - 80 i

Step-by-step explanation:

In order to answer the question, you have to apply the displacement formula, which is:

ΔX= Xf-Xi

Where ΔX is the displacement, Xf is the final position and Xi is the initial position. The formula represents the change in the position of an object from the origin.

Let the origin be in 0 km,with the x-axis positive to te right.

Notice that the displacement is a vector. The positions are:

Xf=163 km (i)

Xi= 243 km (i)

Because John starts in 243 km and finishes in 163 km.

Where i is the unit vector in the x direction.

Therefore:

ΔX= 163 i - 243 i

Solving:

ΔX= -80 i

Notice that for calculating the displacement you just need the initial and final position. It doesn't depend on the distance traveled.

You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed

shusha [124]

Answer:

We inject 60.9628 milliliters of dosage.

Step-by-step explanation:

Given : You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed as 500 ug/ml. The patient's chart Hosts weight as 168 pounds.

To find : How many milliliters (= cc) are you to inject?

Solution :

We know that,

1 pound = 0.453592 kg,

Patient's weight = 168 pounds

Patient's weight in kg = $168\times 0.453592=76.203456$ kg

The dosage is 0.4 mg per kilogram of bod.

So, dosage of patient weight = $0.4 \times 76.2035\ mg = 30.4814\ mg$

We know, 1 micro gram = 0.001 mg

Concentration of drug is given by,

$500\ \text{micro grams/ml}= 500\times 0.001\ \text{mg/ml} = 0.5\ \text{mg/ml}$

Now we are supposed to find milliliters inject,

So, milliliters of dosage required to inject is

$d= \frac{30.4814}{0.5} = 60.9628$

Therefore, We inject 60.9628 milliliters of dosage.

A rectangular prism has a length of 1 1/4 centimeters, a width of 4 centimeters, and a height of 3 1/4 centimeters. What is the

Brut [27]

We know that

[volume of a prism]=length*width*height
length=1 1/4 cm-------> (1*4+1)/4-------> 5/4 cm
width = 4 cm
height=3 1/4 cm---------> (3*4+1)/4------> 13/4 cm
[volume of a prism]=(5/4)*4*13/4-----------> 65/4--------> 16.25 cm³

the answer is
the volume is 16.25 cm³ (16 1/4 cm³)
