Probability measures the likelihood that an event will occur. In this regard, it was right to use probability to establish if event A will occur or not. However, probability is normally quantified between 0 and 1 or between 0% and 100%. In this case, 0 (or 0%) is a measure of impossibility that an event will occur while 1 or (100%) is a measure that the event will occur.

In the current case, 1.36 violates this basic rule as it is more than 1 or the % sign may be missing. In this case, the Nizar should repeat the calculation taking into consideration any mathematical signs.

An 16 16​-oz jar of peanut butter in the shape of a right circular cylinder is 7 7 in. high and 5 5 in. in diameter and sells fo
olya-2409 [2.1K]

Answer:

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

Considering the 16 oz jar,

h = 7 inches

Diameter = 5 inches

Radius = diameter/2 = 5/2

r = 2.5 inches

Volume = 3.14 × 2.5² × 7 = 137.375 inches³

Considering the 29 oz jar,

h = 7.5 inches

Diameter = 5.25 inches

Radius = diameter/2 = 5.25/2

r = 2.625 inches

Volume = 3.14 × 2.625² × 7.5 = 162.27 inches³

1) If the cost is directly proportional to​ volume, then

If 137.375 inches³ cost $1.6

then 162.27 inches³ should cost

(162.27 × 1.6)/137.375 = $1.89

The price of the larger jar would be $1.89

2) If the cost is directly proportional to​ weight, then

If 16 oz cost $1.6, then

29 oz would cost

(29 × 1.6)/16 = $2.9

The price of the larger jar would be $2.9

PLEASE PLEASE PLEASE FIND THE UNKNOWNS WILL GIVE BRAIN TYSM!!
Wittaler [7]

Answer:

Sum of the opposite pair of a cyclic quadrilateral is 180°.

c= 180-102= 78°

c= 180-102= 78°d= 180-92= 88°

 <em><u>intercepted arc</u></em>

=>2(102°)= 140+a°

a=64°

<u>Simillarly</u>

=> 2(d°)= a°+b°

b°= 112°

so ....

<u>a=64°</u>

<u>a=64°b=112°</u>

<u>a=64°b=112°c=78°</u>

<u>a=64°b=112°c=78°d=88</u>
