Answer:
b. If there is a linear relationship between the amount of mercury in a lake and the surface area of the lake, the probability of observing a test statistic of 2.086 is 0.05.
( the null is rejected and alternate is accepted)
Step-by-step explanation:
Here the critical value is t≥ t∝/2(n-2) = ± 2.086
The significance level is ∝= 0.05 and the p- value is also 0.05
Which indicates that there is no correlation between the dependent and the independent variable.
If the p - value is less than 0.05 the null hypothesis is rejected.
There is a 5% chance that the hypothesis is true.
So the null hypothesis should be rejected.
Given these options
a) if------as 2.086 or more extreme is 0.05
2.086 or 0.05 is the same in this case one cannot be more extreme.
c) of 2.086 or greater is 0.05.
b). If there is a linear relationship ------.
This is the alternate hypothesis.
0.05 is not greater than 2.086 in the given question
d) If there is not a linear relationship between the amount of mercury in-----.
This is the claim which is formulated as null hypothesis.
e) if---- 2.086 or more extreme is 0.05.
0.05 is the same as 2.086
At p- value 0.05 we reject the null hypothesis and accept the alternate hypothesis

Find the slope of the line passing through the points (6,6) and (6, -7).
slope: 1
Answer:
The line is a vertical line, which does not have a slope.
Step-by-step explanation:
Slope of a line:
Suppose we are given two points in the format (x,y) of a line. The slope is given by the change in y divided by the change in x.
(6,6) and (6, -7).
Change in y: -7 - 6 = -13
Change in x: 6 - 6 = 0
Slope is a division by 0, which means that the line is a vertical line, which does not have a slope.

81 people passed and 27 failed their Functional Skills Level 2 exams.
Write this as a ratio in its simplest form.
Answer:
The ratio of approved and disapproved people in its simplest form is 3:1.
Step-by-step explanation:
Since 81 people passed and 27 failed their Functional Skills Level 2 exams, to write this as a ratio in its simplest form, the common greatest divisor of both numbers must be obtained:
27 is divisible by 1, 3, 9 and 27
81 is divisible by 1, 3, 9, 27 and 81
Therefore, the common greatest divisor of both numbers is 27. So, since 27/27 is equal to 1, and 81/27 is equal to 3, the ratio of approved and disapproved people in its simplest form is 3 :1.
The ratio in its simplest form is 1 : 3.
Definition of ratioRatio expresses the relationship between two numbers. It is the frequency with which a number is contained in another number. The sign used to represent ratio is ':'.
Expressing in the simplest formIn order to express the given number of people that passed and failed the exam, we have to divide both numbers by the highest common factor until both numbers cannot be divided further to yield a whole number.
Common factor of 27 and 81 = 1, 3, 9, 27
Highest common factor = 27
Expressing in the simplest form = 1 : 3

A quality-conscious disk manufacturer wishes to know the fraction of disks his company makes which are defective. Step 2 of 2 : Suppose a sample of 884 floppy disks is drawn. Of these disks, 831 were not defective. Using the data, construct the 98% confidence interval for the population proportion of disks which are defective. Round your answers to three decimal places.
Answer:
CI = ( 0, 042 ; 0,079 )
Step-by-step explanation:
If from 884 , 831 disks were OK then 884 - 831 = 53 were defective
x = 53
p = 53/884 p = 0,0599 or p = 5,99 % p ≈ 6 %
and q = 1 - 0,06 q = 0,94
p*n and q*n are big enough
For CI 98 % significance level is α = 2 % α/2 = 0,01
z(score) for α/2 = 0,01 is
z(c) ≈ 2,324
CI = p ± z(c) *√p*q/n
√p*q/n = √ ( 0,94*0,06)/884
√p*q/n = √ 0,0564/884
√p*q/n = 0,00799
CI = ( 0,06 ± 2,324*0,00799)
CI = ( 0,06 - 0,0185 ; 0,06 + 0,0185 )
CI = ( 0, 042 ; 0,079 )

B. (0, -3) and (0, -6)
c. (0,3) and (0,6)
D. (3, 0) and (6.0)
Answer:
The answer correct (D).
The x-intercepts for the parabola defined by the equation y= x²-9x+ 18 are (3, 0) and (6.0)
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax2+bx+c=0. with a ≠ 0 .
We have to find the x-intercepts for the parabola y= x²-9x+ 18
We have to make y as zero to find the x intercepts
x²-9x+ 18 = 0
This equation is in the form of quadratic equation
x² -6x-3x+18=0
x(x-6)-3(x-6)=0
(x-3)(x-6)=0
x=3 or x=6
Hence, the x-intercepts for the parabola defined by the equation y= x²-9x+ 18 are (3, 0) and (6.0)

Please help me with these, find the missing side. Thank yu only if you know
Answer:
7.48m (3s.f.)
Step-by-step explanation:
Let the missing side be x m.
Applying Pythagoras' Theorem,
x² +5²= 9²
x² +25= 81
x²= 81 -25 (-25 on both sides)
x²= 56
[tex]x = \sqrt{56} [/tex]

x= 7.48 (3 s.f.)
∴ The missing side is 7.48 m (3s.f.)

what force would be required to accelerate a 1,100 kg car to 0.5m/s?
Answer:
550 N
Step-by-step explanation:
We can solve the problem by using Newton's second law:
[tex]F=ma[/tex]
F is the force required to accelerate the car
m is the mass of the car
a is the acceleration of the car
In this problem, the mass is m=1100 kg, while the acceleration is a=0.5 m/s^2, therefore the force required to accelerate the car is
[tex]F=ma=(1100kg)(0.5m/s^{2} )=550N[/tex]
