C, A, and B are all in the range. That's why you can say it's D. The range is -2≤n≤4. 5 does not work.
0.81 = 0.81 / 1
Numerator = 0.81 × 10 × 10 = 81
Denominator = 1 × 10 × 10 = 100
Numerator / Denominator = 81 / 100
Simplifying our fraction
= 81/100
= 81/100
Hello!
First you have to find the total amount of kids
28 + 76 + 46 = 150
Divide this by the amount of kids per bus
150 / 50 = 3
The answer is 3 buses
Hope this helps!
Considering the given graph, the number of solutions for the system of equations is given by:
b.) one
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In a graph, the number of solutions is given by the number of times the lines intersect. Hence, in this problem, the system has one solution, and option b is correct.

Answer:
The percent of the pairs that last longer than six months—that is, 180 days is 95.637%
Step-by-step explanation:
Mean = xbar = 208 days
Standard deviation = σ = 14
The standardized score for 180 days is the value minus the mean then divided by the standard deviation.
z = (x - xbar)/σ = (180 - 208)/14 = - 1.71
To determine the percent of boots that last longer than 180 days, we need this probability, P(x > 180) = P(z > (-1.71))
We'll use data from the normal probability table for these probabilities
P(x > 180) = P(z > (-1.71)) = 1 - P(z ≤ (-1.71)) = 1 - 0.04363 = 0.95637 = 95.637%
