The sample mean is μ=105, and sample standard deviation is σₓ=.
The Z-score is .
Refer to standard normal distribution table.
The required probability is
Answer:
A
Step-by-step explanation:
Answer:
-3 < x
Step-by-step explanation:
3(x + 2) > X.
Distribute
3x+6 >x
Subtract 3x from each side
3x-3x +6 >x-3x
6> -2x
Divide each side by -2, remembering to flip the inequality
6/-2 < -2x/-2
-3 < x
Absolute or modulus always gives a positive number.
For example, when I take absolute value of 4, I get
|4| = 4 and when I take absolute value of -4, I get |-4| = -(-4) = 4.
Therefore, no matter what the sign of quantity is, absolute or modulus will always make it positive.
Therefore,
<span>|10 blocks| + |3 blocks| + |-8 blocks| + |2 blocks| + |-7 blocks| + |4 blocks| + |-4 blocks| = 10 + 3 -(-8) + 2 -(-7) + 4 -(-4) = 10+3+8+2+7+4+4 = 38</span>
Answer:
1. a certificate of deposit
2. multiply the principal by the interest rate and time
Step-by-step explanation:
1. A CD is a savings vehicle called a "Certificate of Deposit." It generally specifies a certain rate of interest for a given period of time. It usually carries an interest penalty for early withdrawal.
__
2. The interest on a CD is calculated the way it is calculated for any other investment. The amount of interest in a given time is the product of the principal, the interest rate, and the time period. Interest on a CD with a period of more than 1 year is generally compounded. (The compounding interval will be part of the terms of the CD agreement.)
