The answer for this problem is c bc that’s what I think
Answer:
x=6
Step-by-step explanation:
7+5(×-3)=22
expand the brackets:
7 + 5x - 15 = 22
simplify:
5x - 8 = 22
add 8 to both sides:
5x = 30
divide both sides by 5
x = 6

Answer:
To the nearest tenth place, V = 1,810.3 m^3
Step-by-step explanation:
In this question, we are tasked with calculating the volume of a cylinder given its base radius and height.
Mathematically, the Volume can be calculated using the formula
V = pi * r^2 * h
where pi = 22/7 , r = 6m and h = 16m
Plugging these values, we have
V = 22/7 * 6^2 * 16
V = 22/7 * 36 * 16
V = 1,810.286 m^3
To the nearest tenth place, V = 1,810.3 m^3
Answer:
Step-by-step explanation:
Expand parentheses:
Subtract 42 from both sides:
Divide both sides by 14:

Answer:
a) CI = ( 5,1 ; 5,7 )
b) SE = 0,1
Step-by-step explanation:
a) Sample random n = 100
Mean = μ = 5,4
Standard deviation s = 1,3
CI = 99 % α = 1 % α = 0,01 α/2 = 0,005
z(c) for 0,005 is from z-table z(c) = 2,575
z(c) = ( X - μ ) /s/√n CI = μ ± z(c) * s/√n
CI = 5,4 ± 2,575* 1,3/10
CI = 5,4 ± 0,334
CI = ( 5,1 ; 5,7 )
b) SE = Standard deviation / √n
SE = 1,3 /10 SE = 0,1
We can support that with 99 % of probability our random variable will be in the CI.
