Answer:
(a) y = −50x + 250
Step-by-step explanation:
In case you don't realize that the graph starts at 250 and decreases by 50 for each increase of 1 in x, you can see if any of the equations match the given points. The only one that does is the first one:
y = -50x +250
The confidence interval for a <span>(1−α)%</span> confidence level is given by
<span>
(<span>θ0</span>−<span>Z<span>α/2 </span></span><span>σ/√n</span>, <span>θ0</span>+<span>Z<span>α/2 </span></span><span>σ/√n</span>)
</span><span>θ0</span> is the measured statistic, <span>Z<span>α/2</span></span> is the cutoff/critical value, and <span>σ/<span>√n</span></span> is the standard error. σ is the population standard deviation (if known) or can be estimated by a sample standard deviation. n is the sample size.
The cutoff value depends on the test you wish to use, and <span>θ0</span><span> depends on the statistic you wish to estimate.</span>
It's answer is option A.
As the area of circle is given which is 58 square feet, we are to find circumference of the circle.
We know that area = π r^2
Where π = 3.14 and r is radius of the circle
So it will become
3.14 x r^2 = 58
r^2 = 58/3.14
r^2 = 18.4713375796
If we take square root of both sides, we get
r = 4.297829403268585 feet
By using this value of r we can find circumference of the circle,
As,
Circumference = 2 π r
It will become
2 x 3.14 x 4.297829403268585
26.99036
Which is very close to the option A.
<u>Answer:</u>
x = -8
<u>Step-by-step explanation:</u>
We are given the following expression which we are to solve for :
For this expression, we will make the bases same on both sides of the equation and then equate the exponents equal to each other.
Multiplying the exponents and equating them to get:
x = -8
