Answer:
6.25 times 100 will equal to 625. When you multiply by 100, you can move the decimal two spaces to the right since there are two zeros, and you get 625.

Answer:
=4m^2−11m+6
Step-by-step explanation:
Given algebraic expression:
(m-2)(m•2+2m-3)
To:
Simplify
Solution:
(m−2)(m(2)+2m−3)
=(m)(m(2))+(m)(2m)+(m)(−3)+(−2)(m(2))+(−2)(2m)+(−2(−3)
=2m^2+2m^2−3m−4m−4m+6
=4m^2−11m+6
Answer:
t = 1.068 s
Step-by-step explanation:
given,
a(t) =- k v(t)
speed of the object decreases from 800 ft/s to 700 ft/s
distance = 1400 ft
time for deceleration = ?
a(t) =- k v(t)
integrating both side
..........(1)
since,
from equation 1
putting value of k in equation (1)
t = 1.068 s
Answer:
e=14
Step-by-step explanation:
15/21 =10/e
by cross multiplying,
e×15=21×10
15e=210
e=210/15
e=14
Answer:
C.The mean of the sampling distribution is always
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , a large sample size, of at least 30, can be approximated to a normal distribution with mean and standard deviation .
So
A is wrong, because it is
B is wrong, you need a sample size of at least 30.
So the correct answer is:
C.The mean of the sampling distribution is always
