Answer:

Step-by-step explanation:

From the given information:

The null hypothesis is:

[tex]H_o: \mu = 8[/tex]

The alternative hypothesis is:

[tex]H_1 : \mu \ne 8[/tex]

The sample size n = 35

Sample mean = 7.91

variance = 0.03

Standard deviation = [tex]\sqrt{0.03} = 0.173[/tex]

The t-test statistics is computed as:

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

[tex]t = \dfrac{7.91 -8}{\dfrac{0.1732}{\sqrt{35}}}[/tex]

[tex]t = \dfrac{-0.09}{\dfrac{0.1732}{5.916}}[/tex]

t = - 3.0741

Degree of freedom:

df = n - 1

df = 35 - 1

df = 34

Level of significance = 1 - C.I

= 1 - 0.99

= 0.01

The t_{critical} value for the two-tailed test at 0.01 is within the rejection region:

[tex]t_{critical} = -2.728 \ and \ 2.728[/tex]

Decision rule: To reject [tex]H_o[/tex] if  [tex]t< -2.728 \ or \ t > 2.728[/tex]

As [tex]t_{statistics}[/tex] fails the rejection region, we reject [tex]H_o[/tex]

Conclusion: There is sufficient evidence to believe that the machine will not dispense 8 ounces & and it must be stopped for repairs.

You can use hypothesis testing with t test to know if there is enough evidence that he machine should be stopped and production wait for repairs.

There is enough evidence that the machine should be stopped and production wait for repairs.

Let the population mean be denoted by [tex]\mu[/tex]

Null hypothesis: [tex]\mu = 8[/tex] (that is, machine needs no repair and working fine)

Alternate hypothesis: [tex]\mu \neq 8[/tex] (that is, machine is not dispensing right amount and need repairs)

Using t test:

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

[tex]t = \dfrac{7.91- 8}{\dfrac{0.1732}{\sqrt{35}}} = -0.30821[/tex]

Degree of freedom = sample size - 1 = 34

Level of significance = [tex]\alpha = 1 -0.99 = 0.01[/tex]

From t tables we have:

[tex]t_{critical} = t_{0.01} = \pm 0.278[/tex] (two tailed test) (at 34 degree of freedom)

Since obtained value of t -0.30821 is less than the minimum value of range [tex](-0.278, 0.278)[/tex], thus lying outside the range and thus, we cannot accept the null hypothesis and end up accepting the alternate hypothesis.

Thus, there is enough evidence that the machine should be stopped and production wait for repairs.

Hey there!

Usually when you come across the word “of” in mathematical problems , it simply means that you’re multiplying

So we can simply multiply 28.2% from 92

28.2% = 28.2/100 = 0.282

New equation

0.282 * 92 = the answer

0.282 * 92 = 25.944

Good luck on your assignment and enjoy your day!

Step-by-step explanation:

The parent function of the graph is y = √x

The given graph is a graph of a square root function, that is translated upward by 3 units and right by 1 unit

This means that the equation of the graph is:

y = 3 + √(x - 1)

Remove the translated points

y = √x

Hence, the parent function of the graph is y = √x

each class gets 3 and 1/16 pounds

Answer:

let the wages of men and boys be x and y respectively

then

5x+6y = 114

7x + 8y = 157

multiplying equation first by  4 and second by three and subtracting equations

20x + 24y = 456

21x + 24y =471

-x = -15

x= 15 men wages

substituting value of x in equation

5x + 6y = 114

5*15 + 6y = 114

6y = 114 -75

6y = 39

y = 6.5 each boys wages

Hope this helps!

Answer:

Not necessarily. There are many ways to write a basic equation with a negative answer. For example, -3-4 = -7. Here 4 is a positive number but because you subtract 4 to 3 or take away 4 from 3 being a negative number and so you get a negative answer. Another example is 6+(-9). There are a couple of ways you can resolve this. My method is to subtract 9 from 6 which gives you 3 and simply add a negative sign.

Let me know if you'd  like more examples. Hope this helps!! Sorry if it is confusing I can explain you in a more simpler way if you'd like.

Step-by-step explanation:

The sum of two integers is negative, here both integers are negative.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Given that the sum of two integers is negative.

And both integers are negative

Let a < 0, b < 0

Using a model  a + b < 0

Substitute the values a = -1, b = -2, and c = -3 in the inequality of model

⇒ (-1) + (-2)  < 0

⇒ -1 - 2 < 0

⇒ -3 < 0

So, the sum of two integers is negative.

Hence, the sum of two integers is negative, here both integers are negative.
