Answer: 5.5%
Step-by-step explanation:
Since the money invested has grown to $8300 and the principal was $600, this means the interest is:
= $8300 - $6500
= $1800
Simple interest = (Principal × Rate × Time)/100
1800 = (6500 × Rate × 5)/100
Cross multiply
1800 × 100 = 32500 × Rate
Rate = 180000/32500
Rate = 5.5%
Answer:
x = 5
Step-by-step explanation:
If x + 5 = 10, then x would have to be 5 because 5 + 5 = 10.
The way you would solve this would be:
x + 5 = 10
subtract 5 from both sides of the equation
x + 5 - 5 = 10 - 5
simplify:
x = 5

Answer:
And we can find the probability with this difference:
And using the normal standard table or excel we got:
And the best answer would be:
0.3811
Step-by-step explanation:
Let X the random variable that represent the ratings of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
Using the z score we got:
And we can find the probability with this difference:
And using the normal standard table or excel we got:
And the best answer would be:
0.3811
Answer:
D) 1000
Step-by-step explanation:
<u><em>The options of the question are</em></u>
A) -1000 B) -7 C) 7 D) 1000
we know that
The sea level is the reference value to represent elevation, and it is considered as zero level.
Above sea level is considered positive and below the sea level is considered negative
we have
New Orleans is 7 feet below sea level
so
New Orleans elevation is -7 ft
Oklahoma is 1000 feet above the sea level
so
Oklahoma elevation is +1000 ft
therefore
Oklahoma City's elevation is represented by 1000
