Answer: 310
Step-by-step explanation:
You would think it’s 380 because 345 + 35 but since it says the diver is BELOW, that means it’s -35 so, -35 + 345, and the 345 stays as a positive number because they’re above the sea level. 345 + -35, hope this helped.

Use a 0.05 significance level to test the claim that such polygraph results are correct less than % of the time. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use the normal distribution as an approximation of the binomial distribution.

Step-by-step explanation:
Two numbers r and s sum up to \frac{1}{2} exactly when the average of the two numbers is \frac{1}{2}*\frac{1}{2} = \frac{1}{4}. You can also see that the midpoint of r and s corresponds to the axis of symmetry of the parabola represented by the quadratic equation y=x^2+Bx+C.
The equation for the line shown in the graph below is y= 2x + b in slope intercept form.
What is the value of b?
Answer:
-3
The y-intercept is where the line touches the y-axis
On the graph the line touches the y-axis at y=-3
Therefore the y-intercept is y=-3

Grace needs $45 to go to Six Flags. She has $13. She earns $8 an hour walking dogs. Which
equation represents how many hours Grace will have to walk dogs to earn enough money to go
to Six Flags? *
Answer: C. 13 + 8x = 45
Step-by-step explanation:
She already has 13 dollars. This would be the b-value in the equation, thus eliminating options A and B because those two feature 13 as the m value.
She earns $8 per hour. Let x = number of hours walking dogs.
Since 8 is the slope, it would be attached to x, thus either C or D would be the correct response
Since Grace is adding 8 dollars per hour, not subtracting, D is incorrect, leaving C to be the correct answer.

I need help with math homework
Answer:
A. (0, 1) and (2, -2)
B. Slope (m) = -³/2
C. y + 2 = -³/2(x - 2)
D. [tex] y = -\frac{3}{2}x + 1 [/tex]
E. [tex] \frac{3}{2}x + y = 1 [/tex]
Step-by-step explanation:
A. Two points on the line from the graph are: (0, 1) and (2, -2)
B. The slope can be calculated using two points, (0, 1) and (2, -2):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 - 1}{2 - 0} = \frac{-3}{2} = -\frac{3}{2} [/tex]
Slope (m) = -³/2
C. Equation in point-slope form is represented as y - b = m(x - a). Where,
(a, b) = any point on the graph.
m = slope.
Substitute (a, b) = (2, -2), and m = -³/2 into the point-slope equation, y - b = m(x - a).
Thus:
y - (-2) = -³/2(x - 2)
y + 2 = -³/2(x - 2)
D. Equation in slope-intercept form, can be written as y = mx + b.
Thus, using the equation in (C), rewrite to get the equation in slope-intercept form.
y + 2 = -³/2(x - 2)
2(y + 2) = -3(x - 2)
2y + 4 = -3x + 6
2y = -3x + 6 - 4
2y = -3x + 2
y = -3x/2 + 2/2
[tex] y = -\frac{3}{2}x + 1 [/tex]
E. Convert the equation in (D) to standard form:
[tex] y = -\frac{3}{2}x + 1 [/tex]
[tex] \frac{3}{2}x + y = 1 [/tex]
