Circumference (rounding)

Answer:

It will take Julie 2.4 hours to make $30.34

Step-by-step explanation:

⇒ 30.34 = 12.6h + 0.1

⇒ 30.34 -0.1 = 12.6h + 0.1 -0.1

⇒ 30.24 = 12.6h

⇒ 30.24/12.6 = 12.6h/12.6

⇒ 2.4 = h

Answer:

C

Step-by-step explanation:

A= 1/2bh

2/5= 1/2(b)(6/5)

4/5= 6/5b

4=6b

4/6=b

b= 2/3

Answer:

Step-by-step explanation:

1. X/2 when x = 1/2

Putting value of x in the equation

1/2 /2 = 0.25

2. 2x2 - 8 when x = 3

2(3)2 - 8

= 2(9) - 8

= 18 - 8 = 10

3. 4(x - 7)3 + 5 when x = 9

4 (x3 - 21x2 + 147x - 343) + 5

Putting value of x

4((9)3 - 21(9)2 + 147(9) - 343) + 5

4(729 - 1701 + 1323 - 343) + 5

4(8) + 5

= 32 + 5 = 37

Answer:

1. 0.25

2. 208

3. 517

Step-by-step explanation:

Number 1.

0.5/2

= 0.25

number 2.  

2(3)^3-8

6^3 - 8

216-8

= 208

Number 3.

4(9-7)^3 +5

4(2)^3+5

8^3+5

= 517

Answer:

The only factor of 1 is 1. A prime number has exactly two factors so 1 isn't prime. A composite number has more than 2 factors, so 1 isn't composite.

Answer:A

Step-by-step explanation:

Answer:

theoretical- what is expected to happen, 1/2

experimental- what actually happened, 1/10

Step-by-step explanation:

theoretical does not always mean that it will happen, such as flipping a coin.

it will say there is a 1/2 chance to get heads or tail.

experimental is what actually happens when you test it out. say you flip a coin 10 times and only get heads 3 times. if it was the theoretical possibility then it would say 5 heads and 5 tails.

The best prediction possible for the number of times it will land on pink or green is 48 times, As the total probability is 1.

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

Given, A spinner has 4 pink parts and 2 green parts.

The probability that it would land or pink or green is P(P) + P(G).

= (4/6) + (2/6).

= (4 + 2)/6.

= 6/6.

= 1.

Now, We know The expected value, also known as the expectation, average, is a generalization of the weighted average in the field of probability theory. Informally, the anticipated value is the arithmetic mean of a significant number of outcomes of a random variable that were independently chosen.

Therefore, The best prediction possible for the number of times it will land on pink or green is,

= 48[P(P) + P(G)].

= 48(1).

= 48 times.

3,825 / 12.5 / 24 = 12.75

Answer: c = 5h

Step-by-step explanation:

C is equal to the total cost, and h is equal to the number of hats bought.

So, as a verbal equation, we have:

total cost = price x number of hats bought

We know the price ($5) and the variables, so we can substitute these:

c = 5h
