Answer:
The first pair shows equivalent expressions.
Step-by-step explanation:
3(x+2), you would have to distribute 3 among x and 2, also known as expanding the expression. So you'd do 3*x + 3*2, which equals 3x+6
The first equation is 3(x+2)=3x+6
Therefore, the first pair shows equivalent expressions.
Answer:
The approximate volume of the sphere= 4187 cubic units
Step-by-step explanation:
<u>Points to remember</u>
Volume of sphere = (4/3)πr³
Where 'r' radius of sphere
<u>To find the volume of sphere</u>
It is given that the radius of the sphere is 10 units. ,
Here radius r = 10 units
Volume = (4/3)πr³
= (4/3) * 3.14 * 10³
= (4/3) * 3140
= 4186.666 ≈ 4187 cubic units
Question 5 (1 point) What is the mean of this set of data: 78, 79, 80, 80, 89, 89, 92, 93, 94, 95, 95, 95 Round your answer to t
Len [333]
88.3
add all the numbers, you get 1,059 and divide that by how many numbers there are which is 12 and you get 88.3
Answer:
x=4,-2/3
Step-by-step explanation:
To solve for x, we first subtract 8 from both sides.
So 3x^2-10x-8=0
Using the quadratic formula, we get
X=(10+sqrt(100+96))/6 or x = (10-sqrt(100+96))/6
So x=(10+14)/6 or x=(10-14)/6
So x=4 or x=-2/3.
Answer:
Step-by-step explanation:
GIVEN: There is a 
chance of rain on Saturday and a 
chance of rain on Sunday. Assume that the event that it rains on Saturday is independent of the event that it rains on Sunday.
TO FIND: What is the probability that it rains on exactly one day over the weekend.
SOLUTION:
Probability of rain on Saturday 
Probability of not raining on Saturday 
Probability of rain on Sunday 
Probability of not raining on Saturday 
Probability of raining exactly one day over the weekend
Hence probability of raining exactly only one day over the weekend is
