Answer:
4=4x
Step-by-step explanation:
the formula y=mx+b
corresponds to y=slope+y intercept
all proportional relationships start on the origin so the y-intercept is always 0
the fact that the equation y = 4x doesn't have an intercept shows its proportional this can go with any similar equation like y = 4.5x
Answer:
The answer to your question is the letter D. (step 2)
Step-by-step explanation:
Data
P (7, 4) slope = 6
Process
1.- Write the equation of the line
y - y1 = m(x - x1)
x1 = 7 y1 = 4
2.- Substitution
y - 4 = 6(x - 7)
- Simplification
y - 4 = 6x - 42
- Solve for y
y = 6x - 42 + 4
y = 6x - 38 This is the equation in the point-slope form
3.- According to the choices the answer is letter D.
Certain inequalities define the possible side lengths of triangles. For example, a side cannot be greater than the sum of the other two. ...

Answer:
Step-by-step explanation:
Hello!
You have to estimate the mean length of 4000 b.c. human skulls trough a 95% confidence interval.
You know that
n= 6 human skulls
= 94.2mm
S= 4.9
Assuming that the variable X: length of a 4000b.c. human skull (mm) has a normal distribution, to construct the interval you have to use the t statistic:
[ ± 
]
[94.2 ± 2.571 * 
]
[89.06; 99.34]mm
With a 95% confidence level you'd expect the interval [89.06; 99.34]mm to contain the value for the average skull length for humans 4000 b.c.
I hope this helps!
