Answer:
No
Step-by-step explanation:
You should only use t procedures when the sample sizes are less than 30, as that is when the Central Limit Theorem kicks in.
Essentially, t procedures are good for small samples while z procedures are better for larger samples.

Step-by-step explanation:
Answer:
the interest is $975
the total amount is $5975
Step-by-step explanation:
lets use tje formula
I=PRT
where I is interest earned
P is the principal amount(original amount)
R is the rate of interest
and T is the time in years
so
the principal amount is 5000 since it is the original amount
rate is
=0.065
time is 3 years
lets plug these values into our equation:
5000*0.065*3=I
5000*0.065*3=975
the interest is $975
the next part of the question is asking for the balance or the total amount which is principal+interest
5000+975=5975
the total amount or balance is $5975
hope this helps

<u>How to find the maximum height of a projectile</u>
if α = 90°, then the formula simplifies to: hmax = h + V₀² / (2 * g) and the time of flight is the longest.
if α = 45°, then the equation may be written as:
if α = 0°, then vertical velocity is equal to 0 (Vy = 0), and that's the case of horizontal projectile motion.
Answer:
- x = 0 or 1
- x = ±i/4
- x = -5 (twice)
Step-by-step explanation:
Factoring is aided by having the equations in standard form. The first step in each case is to put the equations in that form. The zero product property tells you that a product is zero when a factor is zero. The solutions are the values of x that make the factors zero.
1. x^2 -x = 0
x(x -1) = 0 . . . . . x = 0 or 1
__
2. 16x^2 +1 = 0
This is the "difference of squares" ...
(4x)^2 - (i)^2 = 0
(4x -i)(4x +i) = 0 . . . . . x = -i/4 or i/4 (zeros are complex)
__
3. x^2 +10x +25 = 0
(x +5)(x +5) = 0 . . . . . x = -5 with multiplicity 2
