Answer:
I and III Only
Step-by-step explanation:
The second condition only applies in a sample, but we are looking at an experiment, so it is irrelevant. The first and third conditions apply to all two-sample z-intervals, so these are correct.

Whats the slope of (-3,4) (0, 0)
Answer:
slope = [tex]-\frac{4}{3}[/tex]
Step-by-step explanation:
Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], to find the slope. [tex]m[/tex] represents the slope. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point. So, substitute the x and y values of the points (-3, 4) and (0, 0) into the formula appropriately and solve:
[tex]m= \frac{(0)-(4)}{(0)-(-3)} \\m = \frac{0-4}{0+3} \\m = \frac{-4}{3}[/tex]
Thus, the slope is [tex]-\frac{4}{3}[/tex].
Write in the slope-intercept form an equation of the line that passes through the given points.

I need an answer ASAP
I will give the brainiest!
Answer:
y=17/3x-26
Step-by-step explanation:
So what you need to do is find the slope and y-intercept. Then, you write it in y=mx+b form. m=slope, b=y-intercept. So in this case, 17/3 is the slope, and -26 is the y-intercept. Hope this helps :)

The triangle that it formed is given in the figure,
Now first we have to find angle A,
sin(A) =perp/hyp = 1.3/5 = 0.26
now we get ,
Angle A = 15 degree
now using ,
tan(15) = perp/base = 1.3/distance
distance = 1.3/tan(15)
distance =1.3/0.27
distance = 4.8 m

(a) Which is larger, f(1) or g(1)?
f(1) is larger
g(1) is larger
Answer:
g(1) is larger
Step-by-step explanation:
Given
See attachment for graph
Required
Determine which is larger; f(1) or g(1)
From the attachment, the red curve represents f(x) while the blue curve represents g(x)
Next, we determine the values of f(1) and g(1).
f(1) is the point where x = 1 on the y-axis (for the red curve)
So: [tex]f(1) = 1[/tex]
g(1) is the point where x = 1 on the y-axis (for the blue curve)
So: [tex]g(1) = 2.8[/tex]
By comparison:
[tex]2.8 > 1[/tex]
So, g(1) is larger

Which value of m makes this equation true? m - 8 = -1
m = 9
m=7
m= -9
m = -7
Answer:
The answer is 7 because if we write 7 - 8 = -1, then we could see that the answer would be -1 since 7 is 1 value lower than 8, and 8 - 8 = 0, so if 7 is lower than 8 by 1, then you would go one value lower from 0, which is -1. You can also figure this out by looking at a number line and starting from 7 and then going backwards 8 times and whatever number you land on after going back 8 times is your answer.

The number factor of a variable term is called the
a) variable
b) constant
c) algebraic expression
d) numerical coefficient
The number factor of a variable term is called the numerical coefficient.
Algebraic expression are made of terms . Terms might be a signed numbers, a variable, or a constant multiplied by a variable or variables.
Examples of an algebraic expression is as follows:
4x + 7When a constant is multiplied by a variable or variables , that constant is called the coefficient.
In our example the variable is x . The number factor of the variable term x is called the numerical coefficient .
Therefore, the numerical coefficient in our case is 4.
