A: m ≥ -2 and m < 1
B: m ≤ -2 or m > 1
C m ≥ -4/3 and m < 5/3
D: m ≥ - 4/3 or m < 5/3
The solution to the conjunction -5 ≤ 3m + 1 < 4 is m ≥ -2 and m < 1.
To solve the conjunction -5 ≤ 3m + 1 < 4, we need to solve the two inequalities separately. Starting with the left inequality: -5 ≤ 3m + 1. We subtract 1 from both sides: -6 ≤ 3m. Dividing both sides by 3, we get: -2 ≤ m. Next, we solve the right inequality: 3m + 1 < 4. We subtract 1 from both sides: 3m < 3. Dividing both sides by 3, we get: m < 1. Therefore, the solution to the conjunction is m ≥ -2 and m < 1. This means that m is greater than or equal to -2, but less than 1.

A regression line must pass through all the points on the scatter plot.
A regression line cannot help predict future values of variables.
Scatter plots can be used to represent quantitative data.
Answer:
On the Scatter Plot, the two variables associated with each other when represented in Quantitative form that is in the form of x-values and y-values, it can be drawn in two dimensional coordinate plane, Representation being a line.
1.The Line may pass through all the points , a single point or none of the points.
2. It can also predict the future values that is for given x , we can find y and for given y , we can find x.
So, only option (4) which is,Scatter plots can be used to represent quantitative data is true.
The answer is letter D.
Answer:
$2764.8
Step-by-step explanation:
32ft * 24ft = 768ft²
1ft² = 3.6
768*3.6 = 2764.8
The correct option is b.
A quadratic equation is an equation that can be written in the form of
ax²+bx+c.
Where a is the leading coefficient, and
c is the constant.
The leading coefficient of an equation is a coefficient of the term having the highest power in the equation.
Given options:
a.)
b.)
c.)
d.)
As it is given that the leading coefficient of the equation is 3. therefore, the value of the 'a' in the general quadratic equation is 3,
3x²+bx+c,
Also, the value of the constant is -12, therefore, the value of c is -12,
3x²+bx-12
From all the given options the only feasible option is b only.
Hence, the correct option is b.
