The lengths of two sides of a triangle are 7.8 cm and 5.6 cm. Between what two measures should the length of the third side fall

zloy xaker [14]

Hello! To draw a triangle, first, we have to follow a condition of existence.

This rule is:

• one of the sides must be ,bigger, ,than the absolute value, of the ,difference between the other two, sides

• the unknown side must be ,smaller ,than the ,sum of the other, two sides.

Let's write these rules using a, b, and c for the sides:

Considering a = 7.8 and b = 5.6:

[tex]\begin{gathered} |a-b|So, the third side must be smaller than 13.4 and bigger than 2.2.

Suppose two 1-6 number cubes are rolled. find the probability of each outcome. P(1 or 5)

stich3 [128]

Answer:

The probability of each outcome rolling two numbered cubes is 1/36 or 2.8% (Rounding to the next tenth)

Step-by-step explanation:

Probability of each outcome with one cube = Number of favorable events for each outcome/Total number of possible events

Replacing with the real values, we have:

Probability of each outcome with one cube = 1/6

Probability of each outcome with two cubes = 1/6 * 1/6 = 1/36

The probability of each outcome rolling two numbered cubes is 1/36 or 2.8% (Rounding to the next tenth)

The formula for area of a triangle is:

1/2(b*h)

Therfore;

b=4, h=3

So,

1/2(4*3)

1/2(12)

=1/2 * 12

A doctor can prescribe one of two drugs to treat a certain disease. Drug A will cure 75% of the cases but has unwanted side effe

Phoenix [80]

The total number of patients experienced unwanted side effects is 48

Explanation

60 patients are given drug A and drug A has unwanted side effects in 40% of the cases.

So, the number of patients experienced side effects for drug A = 40% of 60 $=(0.40*60)= 24$

Now 80 patients are given drug B and it has side effects in 30% of the cases.

So, the number of patients experienced side effects for drug B = 30% of 80 $=(0.30*80)= 24$

So, the total number of patients experienced unwanted side effects $= 24+24 =48$
