Where the population standard deviation is known, the test statistic is determined to be -2.5. What is the p-value for this test?

Answers

Answer 1

Answer:

[tex]P(Z<-2.5) =0.0062097[/tex]

Step-by-step explanation:

From the question we are told that:

Test statistic t =-2.5

Generally the equation for Test for statistics is mathematically given by

 [tex]t=\frac{\=x-\mu}{\frac{s}{\sqrt{n} } }[/tex]

 [tex]t=-2.5[/tex]

Therefore

P-value from Z table is

For left tailed test

 [tex]P(Z<-2.5) =0.0062097[/tex]

therefore the P-value for the test is

 [tex]P(Z<-2.5) =0.0062097[/tex]

Answers

First you start solving each mixed fraction:
17/10 - 3/2
Now we have improper fractions; fractions that have a numerator larger than the denominator
Next we will find the common denominator using LCM but what I personally do is I multiply both sides by the opposite fraction’s denominator, like this:
17 x 2 _ 3 x 10 —-> 34 - 30
10 x 2 2 x 10 20 - 20

Now we have 34/20 - 30/20 and with the help of collecting the common denominator, all we have to do now is subtract 30 from 34, and our answer will be 4/20
**when we have the same number as our denominator we only add or subtract the numerator, depending on what question your teacher asks you to answer
*** sum = addition/adding
difference = subtraction/subtracting/taking away
The correct answer is 1/5
At first when you subtract you will get 4/20 however answers should always be in reduce /simplified do answer is
1/5

Answer: 80°

Step-by-step explanation:

Since, If two secants intersect outside the circle, then the measure of the angle formed is one half of the difference  of the measures of the intercepted arcs.

In the given diagram,

Chord VS and chord UT are intersecting externally,

Also, ∠SPT is the angle formed by the intersection of these chords.

Thus, by the above property,

Answers

Answer:

B; 1

Step-by-step explanation:

Firstly, we need to find the inverse of the given function

Let us have f(x) as y

To find the inverse, we set out to make x the formula subject

Thus;

y = √(3x + 6)

square both sides

y^2 = 3x + 6

3x = y^2 - 6

x = (y^2 - 6)/3

To write the inverse, replace y by x

So we have the inverse of the function as ;

(x^2 - 6)/3

So what we have to do here is to substitute 3 for x in the inverse

We have this as;

(3^2 -6)/3

(9-6)/3

= 3/3 = 1

Answer:

1 ( option B )

Step-by-step explanation:

The given equation is ,

[tex]\implies f(x) =\sqrt{ 3x + 6 }[/tex]

Now substituting y = f(x) , we have ,

[tex]\implies y=\sqrt{ 3x + 6 }[/tex]

For finding the inverse , Interchange x and y , we have ,

[tex]\implies x =\sqrt{ 3y + 6 }[/tex]

Now solve for y , we have ,

[tex]\implies x ^2=3y + 6 \\\\\implies 3y = x^2-6 \\\\\implies y =\dfrac{x^2-6}{3} [/tex]

Now replace y with f-¹(x) , we have ,

[tex]\implies f^{-1}(x) =\dfrac{x^2-6}{3} [/tex]

Now put x = 3 , we have ,

[tex]\implies f^{-1}(3) =\dfrac{3^2-6}{3}\\\\\implies f^{-1}(3) = \dfrac{9-6}{3}\\\\\implies \underline{\underline{ f^{-1}(3) = 1 }} [/tex]

The volume can be found by adding the volumes of a cylinder (the upper part of the figure) and a cone (the lower part of the figure).

Volume of Cylinder:  [tex]V=\pi r^2 h=\pi(3^2)(3)=27\pi\approx 84.823 \text{ cubic feet}[/tex]

Volume of Cone:  The height of the cone is 3 feet (the whole figure is 6 feet tall and the cylinder uses up 3 feet of that -- 6 - 3 = 3).

[tex]V=\frac{1}{3}\pi r^2 h=\frac{1}{3}\pi(3^2)(3)=9\pi\approx 28.274[/tex]

The total volume is 84.823 + 28.274, about 113.1 cubic feet

so red would be the most oftenblue would be second most oftengreen and white are tied for third

lets say it landed on red 16 timesif we do the math of 16/2 we get 8it landed on blue 8 timeshalve that again which is 4it landed on green 4 times and blue 4 timeswhich means out of 32 rolls we got red 16 times, blue 8 times, and green 4 times ad white 4 times
