Answer:
1/9
Step-by-step explanation:
The possible choices 2,3,4
odd numbers: 3
P (odd number) = number of odd numbers /total
= 1/3
Then we spin again
The possible choices 2,3,4
We want a 3: 3
P (3) = number of 3's /total
= 1/3
Since the first spin did not affect the second spin
P(odd, then 3) = P(odd) *P( 3)
= 1/3* 1/3
=1/9
Answer:
38.47 sq cm
Step-by-step explanation:
still use the area formula of π·r² but then divide by 4 (since it's 1/4 of a full circle)
A = 3.14(7²) / 4
A = 38.47
Answer: Less than 25%
Step-by-step explanation:
1. Find the difference of the two numbers: 1,207 - 957 = 250
decrease = original number - new number
2. Then, divide the decrease by the original number
250/1,207 = 0.207
3. Multiply the answer by 100 to get the percentage
0.207 x 100 = 20.7%
Therefore, the number of people fell by 20.7%
Hence, the answer is less than 25%
5(2x-3)=155
10x-15=155(solve/multiply 5 by the numbers/variables in the parentheses first)
10x=170(add 15 to each side)
Divide 170 by 10x
170÷10x=17
x=17
We have an equation: 270/?= 7.5/100
Cross multiply:
7.5*?= 270*100
⇒ ?= 270*100/7.5
⇒ ?= 3600
