The correct interpretation of the p-value is given by:
B If the average battery life really is 5 hours, then a sample of 10 observations having a sample mean of 4.25 hours or lower would only occur about 3.8% of the line.
How to find the p-value of a test?It depends on the test statistic z, as follows:
For a left-tailed test, it is the area under the normal curve to the left of z, which is the p-value of z.For a right-tailed test, it is the area under the normal curve to the right of z, which is 1 subtracted by the p-value of z.For a two-tailed test, it is the area under the normal curve to the left of -z combined with the area to the right of z, hence it is 2 multiplied by 1 subtracted by the p-value of z, which means that the p-value for a two-tailed test is twice the p-value of a one-tailed test.In this problem, a left-tailed test is used, as we are testing if the mean is less than 5 hours.
The sample mean from the 10 times was of 4.25, and the p-value is of 0.038, which means that the area to the left of Z under the normal curve is of 0.038, that is, a sample mean of 4.25 hours or lower would only occur about 3.8% of the line, hence option B is correct.

What is the equation of the line that passes through the point (7,-3) and has an undefined slope?
Answer:
x=7
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
A line with undefined slope is a vertical line. A vertical line has the equation
x = anumber
The point you were given has an x and a y...(x,y) The first number is the x.
x = 7
That's it, thats the equation of a line with undefined slope that goes through (7, -3).
<<<Fun fact: Lines with 0 slope are horizontal lines and have the equation
y = anumber >>>

Answer:
Step-by-step explanation:
The scale factor for each side is
12/7 = 1.714
What that means is that if you multiply the side length of the small square by the scale factor, you get the side length of the large square.
7 * 1.714 = 11.998 which is not exactly 12, but it is close enough.
Which system of equations does this graph represent?
Answer:Two solution
Step-by-step explanation:
System of the equations consists of a straight line and parabola will be [tex]y = x - 4[/tex] and [tex]y = x^{2} + 4[/tex].
What is system of equation?" A system of equations is a finite set of equations for which we find the common solution."
According to the question,
Y - intercept of line = ( 0, -4)
X - intercept of line = ( 4 , 0)
Standard equation for straight line y = mx +c
m = slope
c = y - intercept
Slope of the line 'm' = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
= [tex]\frac{0-(-4)}{4-0}[/tex]
= [tex]\frac{4}{4}[/tex]
= 1
y- intercept 'c' = - 4
Substitute the value to get the equation of line we get,
Equation of the line y = x - 4
For equation of parabola,
Standard equation of parabola y = (x-h)² + k
Vertex (h, k) = ( 0,2)
Substitute the value of the vertex we get,
y = (x-0)² + 2
⇒y = x² + 2
Hence, system of the equations consists of a straight line and parabola will be [tex]y = x - 4[/tex] and [tex]y = x^{2} + 4[/tex].

The variables x and y are proportional. Use the values to find the constant of proportionality. Then write an equation that relates x and y .
When y=72 , x=3 .
Answer:
equation: y = 24x
Step-by-step explanation:
if y and x is proportional,
y = kx
72 = k * 3
k = 24
→ Here the constant if 24
so the equation that relates x and y :
y = 24x

Answer:
1) y = -1.5x - 1 || 2) y = -1.5x + 1 || 3. D ( 2 , -8 )
Step-by-step explanation:
1)
two coordinates: ( 0 , -1 ) , ( 2 , -4 )
slope = ( y2-y1 )÷(x2-x1) = (-4--1)÷(2-0) = -1.5
then find equation using: y - y1 = m ( x - x1 )
: y - - 1 = -1.5 ( x - 0 )
: y = -1.5x - 1
2)
two coordinates: ( 0 , 1 ) , ( -2 , 4 )
slope = ( 4 - 1) ÷ (-2-0) = -1.5
Find equation using y = mx +b ........where m is slope and b is y-intercept
y = -1.5x + 1
3)
y + 8 = 3(x -2 )
y = 3x -14 ..........main equation in slope intercept form.
A)
y = 3(-2)-14
y = -20 .therefore option A is incorrect
B)
y = 3(8)-14
y = 10 .therefore option B is incorrect
C)
y = 3(-8)-14
y = -38.therefore option C is incorrect
D)
y = 3(2)-14
y = 6 -14
y = -8 . therefore it matches and is correct answer.
the line crosses D( 2 , -8 )

What is the value of x
Check the picture below.
24 cm ,18cm ,c
We are looking for c
Step-by-step explanation:
we can find the value of c by Pythagoras theorem
according to Pythagoras theorem
h² = a² + b²
where
h = hypotenuse (i.e. longest side of a right angled triangle)
a = side
b = base
so, we have to find h or hypotenuse here
h² = (24)² + (18)²
h = 576 + 324 = 900
h² = √900 = 30
c = 30
therefore, value of c is 30.
