Answer:
9^6
Step-by-step explanation:
When dividing exponents with the same base, we subtract the exponents
a^b/ a^c = a^(b-c)
9^11/9^5 = 9^(11-5)
= 9^6
Answer:
Part A: yes
Part B: 50%
Step-by-step explanation:
There are two ways we can use a normal approximation for a sample: if the population it is from is normally distributed, or if the sample is sufficiently large (n > 30). In this case, we don't know if the population is normally distributed, but we do know the sample size is larger than 30, so we can use normal approximation.
The sample proportion is normally distributed, with a mean equal to the mean of the population. So there is a 50% chance that sample proportion is less than the population proportion.
Answer:
1/2x^2 -3
Step-by-step explanation:
The first equation is 1/2x^2 + 1 and since this equation is the first one minus 4 1-4= -3 so you would get this new equation.
Answer:
h = 5.705m
Step-by-step explanation:
Volume of a cylinder
V = πr^2h
V - volume of the cylinder
π - pie
r - radius of the cylinder
h - height of the cylinder
Given :
V = 363 cubic meters
d = 9m
h = ?m
d = 2r
d - diameter
r - radius
r = d/2
r = 9/2
π- 3.142
Insert the values into the formula of volume of cylinder
V = πr^2h
363 = 3.142 * (9/2)^2 * h
363 = 3.142 * 81/4 * h
363 = 63.6255h
Divide both sides by 63.6255 to get the value of h
363/63.6255 = 63.6255h/63.6255
5.705 = h
h = 5.705m
Answer:
son: 12 daniel: 32
Step-by-step explanation:
daniel is 26 in 6 years he would be 32
son is 3x younger in 6 years so 32 divided by 3 would be 10.6 (11 if estimated)
