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:

y = 3/2x + 3/2

Step-by-step explanation:

perpendicular to: y = -2/3x + 5

so slope of new line must be 3/2

y = mx + b

3 = 1(3/2) + b

6/2 = 3/2 + b

b = 3/2

you would cross multiply meaning 6(2x+2)=11(x-4) Then you distribute 6 so it would be 12x+12=11x-44 then you have to move the constant and the variable so 12x-11x= -44-12 so then the answer would be x = -56

Divisors of 78 1,2,3,6,13,26,39,78

Step-by-step explanation:

x²-9/x²-3x

x²-9 simplifies to (x+3)(x-3)

x²-3x simplifies to x(x-3)

cancel out the common term of (x-3) from the numerator and denominator to obtain

x+3/x

Answer:

Option B

Step-by-step explanation:

The figure that can be formed from the net must definitely be the figure that has a square base with its side measuring 4 cm each and a slant height of 6 cm.

This, the figure in option B can be formed form the net because it has the same base measurement of 4 cm and slant height of 6 cm as with the net.

2 numbers are 10 units from 0

Step-by-step explanation:

2 numbers are 10 units from 0.  If you start from zero and count 10 units  to the right, you should be at a positive number.  But, you can also move 10 units to the left. If you do this, you should be at a negative number that  is ALSO 10 units away from 0, just in a different direction than positive number. both are 10 units from 0.   There always 2 numbers, one 10 units to the right of zero, and one 10 units to the left of zero. Hope this helped!  Tell me if I'm wrong or right.

Answer: 2 numbers

Step-by-step explanation:

I'm assuming you are talking about a normal number line and if so, you can count 10 units up and down.

When you do that, you find -10 and 10 which are two numbers so the answer would be 2 numbers

This is assuming that you are talking about a normal number line

Please tell me if I'm right or wrong and I hope this helps someone!

Answer:

Because a MAD is the average of distances, which can never be negative, the MAD is always zero or a positive number.

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.

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

Table of g(x)

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

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.
