Answer:
6
Step-by-step explanation:
Mr. Kramer has pencils for his class = 30
Students in his class = 22
Pencils he would like to give each student = 2
How many more pencils does Mr. Kramer need to buy so that each student will receive 2 pencils = ?
Total pencils Mr. Kramer need to buy so that each student will receive 2 pencils = 22 × 2
= 44
= 44 - 30
= 6
Mr. Kramer need to buy 6 more pencils so that each student will receive 2 pencils
Standard error (SE)

Or

Therefore, SE of the mean = (8)/(2) =4
Number of plants = 5
Amount of soil present for 5 plants = 3/4 gallons
Now here we have to find how much soil will each plant get.
So we have to apply unitary method here to find how much would each plant get the share of soil.
Soil required by 5 plants = 3/4 gallons
Soil required by 1 plant = 3/4 divided by 5 = 3/20 gallons
Answer: Each plant will get 3/20 gallons of soil.
Answer: 10x+16
Step-by-step explanation:
Use the distributive property a(b+c)= ab+ac
so
-2(-5x-8) = (-2 * -5x) - (-2* -8)
=
10x-(-16)
=10x+16
Hope this helped!
