Answer:

$\frac{5}{12}$

Step-by-step explanation:

There are three months whose name starts with the letter 'j': January, June, July

There are two months whose name starts with the letter 'm': March, May

So altogether, there are 5 months whose name starts with the letter 'j' or 'm'. So the possible outcome is 5 and total number of sample space is 12.

Therefore the required probability is:

$\frac{5}{12}$

If Colorado spring, Colorado, has 1.2 times as many days of sunshine as Boston, Massachusetts, how many days of sunshine does ea

Crank

C= Colorado B= Boston
C + B = 464
C = 1.2B
Substitute the known value of C from the second equation into the first
C + B = 464
(1.2B) + B = 464
2.2B = 464
Divide each side by 2.2
B = 210.9, rounded to 211 (it's asking for days, not partial days, so round)
If Boston has 211 days of sunshine , then Colorado Springs has 1.2 times that amount. 211 * 1.2 = 253.2 (rounded to 253)
Verification
211 + 253 = 464

Answer:

didn't give clear instructions on what to do. I just assumed you add them. answer is down below. :)

Step-by-step explanation:

if ur supposed to add them then

1. 1/8 + 8/8 + 3/8 = 12/8 = 1 1/2

2. 1/4 + 2/4 + 1/4 = 4/4 = 1

3. 1/8 + 8/8 + 4/8 = 1 5/8

4. 1/4 + 1/4 + 2/4 = 4/4 = 1

5. 1/4 + 1/4 + 1/4 + 1/4 = 1

When making a guess and retesting this information, a theory or ___________ may be formed which explains why something has occur

podryga [215]

Model 

When making a guess and retesting this information, a theory or model may be formed which explains why something has occurred or what it may look like. Models are a representation of a certain situations that has occurred. These models can provide and amplify a clearer perception and comprehension of how and what processes are involved in an occurred phenomenon. And by that said, it can change and be modified depending on which factor catalyzed the alterations.
