Area= (20x13)x2+(10x12x1/2)x2+10x20

=520+120+200

=840

Area=Two area of the triangle [13x20] + Two area of the rectangle + Under area (rectangle)- [10x20]

An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 6.5 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 26 engines and the mean pressure was 6.6 pounds/square inch with a standard deviation of 1.0. A level of significance of 0.01 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.

Answers

Answer:

The calculated value t = 0.510 < 2.7874 at 0.01 level of significance

The null hypothesis is accepted at 0.01 level of significance

The engineer designed the valve such that it would produce a mean pressure of 6.5 pounds/square inch

Step-by-step explanation:

Step:-1

Given that mean of the population (μ) = 6.5 pounds/ square inch

Given that the sample size 'n' = 26

Given that mean of the sample ( x⁻) = 6.6  pounds/ square inch

Given that the standard deviation of the sample (σ) = 1.0

t₀.₀₁ = 2.7874

Step:-2

Null hypothesis:H₀:  μ = 6.5

Alternative Hypothesis:H₁: μ ≠6.5

Test statistic

         [tex]t = \frac{x^{-}-mean }{\frac{S}{\sqrt{n} } }[/tex]

        [tex]t = \frac{6.6-6.5}{\frac{1.0}{\sqrt{26} } }[/tex]

       t =  0.510

 The calculated value t = 0.510 < 2.7874 at 0.01 level of significance

Final answer:-

The calculated value t = 0.510 < 2.7874 at 0.01 level of significance

The null hypothesis is accepted at 0.01 level of significance

The engineer designed the valve such that it would produce a mean pressure of 6.5 pounds/square inch

Answer:

base = 3 units

height = 5 units

area = 1/2 x 3 x 5 = 7.5 square units

Answer:

[tex]b[/tex] = 3 units

[tex]h[/tex] = 5 units

[tex]a[/tex] = 7.5 units

Step-by-step explanation:

We can find the base of the figure by counting the number of units from the left to the right of the triangle. So, we can find that the base is 3 units.

The height of the figure can be found by counting how many units the figure measures from the tip to the bottom. The height, then, is 5 units.

The easiest way to find the area of a right triangle is to imagine it as a rectangle, with the same [tex]l[/tex] (length) and [tex]w[/tex] (width) dimensions, and then divide the area of the rectangle by two.

So, to find the area of this rectangle, multiply the length and width, 3 and 5, together.

3 · 5 = 15

Then, we can divide this product by two.

[tex]\frac{15}{2}[/tex] = 7.5

The area is 7.5 units².

Hope this helped :] Good luck!

A bowl is in the shape of a hemisphere. The radius of the bowl is 10 centimeters. How many liters of water can the bowl hold?
(1,000 cm = 1 liter)

Answers

Answer:

The bowl can hold 2.094 L.

Step-by-step explanation:

We want to find the volume of the hemisphere to calculate how many liters the bowl can hold. To find the volume of a hemisphere, we use this equation:

V = (2/3)•(π)•(r)³

Let's plug in what we know.

V = (2/3)(π)(10)³

Evaluate the exponent.

V = (2/3)(π)(1000)

Multiply.

V = 666.667π

V = 2094.395 cm³

Remember that 1000 cm = 1 liter, and we want to know how many liters the bowl can hold.

= 2094.395/1000

= 2.094 L

The bowl can hold 2.094 L.

Hope this helps!

Answers

The functions f and g have the same axis of symmetry, and the y-intercept of f is less than the y-intercept of g.

How to interpret the functions f(x) and g(x)

Using the attached figure as a guide, we have the following summary

Graph of f(x)

The y-intercept: y = 5Axis of symmetry: x = 2The x-intercept: x = -1 and x = 5

Table of g(x)

The y-intercept: y = 8Axis of symmetry: x = 2The x-intercept cannot be determined

From the above summary, we can see that the functions have the same axis of symmetry but different y-intercepts
