Answer:

Part A) The probability is closer to 0, because is less than 50%

Part B) The probability is closer to 1, because is greater than 50%

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.

The size of the sample space is the total number of possible outcomes

The event space is the number of outcomes in the event you are interested in.

Let

x------> size of the event space

y-----> size of the sample space

$P=\frac{x}{y}$

Part A) Is the probability of hitting the black circle inside the target closer to 0 or 1?

In this problem we have

x------> is the area of the black circle

y------> is the total area of the square target

Find the area of black circle

$r=3/2=1.5\ units$

$x=(3.14)(1.5)^{2} =7.065\ units^{2}$

Find the total area of the square target

$y=9^{2}=81\ units^{2}$

Find the probability

$P=\frac{7.065}{81}=0.0872$

Convert to percentage

$0.0872*100=8.72\%$

The probability is closer to 0, because is less than 50%

Part B) Is the probability of hitting the white portion of the target closer to 0 or 1?

In this problem we have

x------> is the area of the white portion of the target

y------> is the total area of the square target

Find the area of the white portion

The area is equal to the area of the square minus the area of the circle

$x=81-7.065=73.935\ units^{2}$

Find the probability

$P=\frac{73.935}{81}=0.9128$

Convert to percentage

$0.9128*100=91.28\%$

The probability is closer to 1, because is greater than 50%

Subtracting using a number line start at 5/6 and move backwars. 4/6. Where did you stop? 5/6 - 4/6=

ziro4ka [17]

Answer:

1/6

Step-by-step explanation:

5/6 and 4/6 have the same common denominator so you dont have to mess with the bottom numbers. all you will do is subtract 5-4=1. now you have 1/6

70 POINTSS!!!!!!! ANSWER ASAP write a paragraph on what you've learned about exponents and why some people may utilize exponents

lara [203]

I learned that Exponents are important in math because they allow us to abbreviate something that would otherwise be really tedious to write. If we want to express in mathematics the product of x multiplied by itself 7 times, without exponents we'd only be able to write that as xxxxxxx, x multiplied by itself 7 times in a row. , from exponents I

Question 22 of 25

Xelga [282]

Answer:

<h3>Option D</h3>

The value of y in the parallelogram is 34°

Step-by-step explanation:

Adjacent angles of the Parallelogram are supplementary

So,

(78° + 3y°) = 180°

78° + 3y° = 180°

Subtract 78° each side we get,

78° - 78° + 3y° = 180° - 78°

3y° = 102°

Now, Divide both side by 3 we get,

3y°/3 = 102°/3

y = 34°

Thus, The value of y in the parallelogram is 34°
