Answer:
true
Step-by-step explanation:
because the expression shown is a monomial we simply add the degrees of each term
4 + 2 + 3 = 9
5x4y2z3 indeed has a degree of 9
Note: if the terms were being added we take the highest degree and that is the degree of the expression.
ex. 5x^4 + y^2 + z^3 would have a degree of 4
Number of matchsticks required is 2. Rule which matchstick pattern is 2 x n.

Answer:
C. 47.5%
Step-by-step explanation:
The summary of the given statistics include:
mean =150000
standard deviation: 1200
The objective is to use tributed with a mean of $150,000. Use the 68-95-99.7 rule to find the percentage of buyers who paid: between $150,000 and $152,400
The z score formula can be use to calculate the percentage of the buyer who paid.

For the sample mean x = 150000


z = 0
For the sample mean x = 152400


z = 2
From the standard normal distribution tables
P(150000 < X < 152400) = P(0 < z < 2 )
P(150000 < X < 152400) =P(z<2) -P(z<0)
P(150000 < X < 152400) =0.9772 -0.5
P(150000 < X < 152400) = 0.4772
P(150000 < X < 152400) = 47.7% which is close to 47.5% therefore option C is correct
