1.He plotted y= -(0.4^x)+3
He did not bracket properly so this is the graph.
2.
<span>C. The graph decreases from left to right.
</span><span>D. The point (4, 1.72) is on the graph.
</span><span>E. The graph has a y-intercept only.
</span><span>D. Quadrants I and IV only
Imagine a J shape from quad 4 extend to quad 1. </span>

Calculate the sample standard deviation
First, calculate the mean
The sample standard deviation is then calculated using:
So, we have:
-- approximated
The expression for T-shirt production is 20+9T
The expression for total price of selling the T-shirts is 15T
Profit = Total cost of selling - Total cost of buying
Profit = 15T - (20+9T)
Profit = 15T - 20 - 9T
Profit = 6T - 20
To make profit ≥150
6T - 20 ≥ 150
6T ≥ 170
T ≥ 170/6
T ≥ 28.3
The minimum number of T-shirts needed is 29 T-shirts
Answer:
GCF = 12
Step-by-step explanation:
72 = 2³·3²
84 = 2²·3·7
Common prime factors are 2 and 3. The lowest power of 2 is 2; the lowest power of 3 is 1. The greatest common factor is 2²·3 = 12.
The batting average of a baseball player is classified as a numeric continuous variable.
<h3>What are categorical and numerical variables?</h3>
- Categorical variables assume labels, for example, good or bad.
- Numerical variables assume numbers, as it own name says.
A batting average is given by the <u>number of hits divided by the number of at bats</u>, hence it is a numeric value.
<h3>What are continuous and discrete variables?</h3>
- Continuous variables assume real values.
- Discrete variables assume integer values.
The batting average is a real number, hence it is also a continuous variable.
