Two interior angles of a triangle are 54 and 112. What is the measure of the third angle?

Answers

Answer: 14 degrees.

Step-by-step explanation: The sum of the measures of the interior angles of a triangle is always 180 degrees. Therefore, if we know the measures of two of the interior angles of a triangle, we can use this fact to find the measure of the third angle.

In this case, we are given that two of the interior angles of the triangle have measures of 54 and 112 degrees. We can use this information to find the measure of the third angle as follows:

180 degrees = 54 degrees + 112 degrees + x

180 degrees = 166 degrees + x

x = 180 degrees - 166 degrees

x = 14 degrees

Therefore, the measure of the third angle of the triangle is 14 degrees.

an engineer has designed a valve that will regulate water pressure on an automobile engine. the valve was tested on 170 engines and the mean pressure was 6.7 lbs/square inch. assume the standard deviation is known to be 1. if the valve was designed to produce a mean pressure of 6.6 lbs/square inch, is there sufficient evidence at the 0.05 level that the valve performs above the specifications? state the null and alternative hypotheses for the above scenario.

Answers

There is sufficient data to infer that the valve does not operate as intended at the 0.1 level.

Null hypothesis: H₀ : μ = 7.6

Alternative hypothesis: Hₐ : μ ≠ 7.6

What is the Null hypothesis?

In inferential statistics, the null hypothesis states that two possibilities are equal.

The observed difference is thought to be the sole product of chance, which is the underlying premise.

Statistical tests can be used to calculate the likelihood that the null hypothesis is true.

So,

Null hypothesis: H₀ : μ = 7.6

Alternative hypothesis: Hₐ : μ ≠ 7.6

As the population standard deviation is given when n > 30

So, we'll run the Z test.

Formula: [tex]z=\frac{x-\mu}{\frac{a}{\sqrt{n}}}[/tex]

Replace the values:

[tex]\begin{aligned}& z=\frac{7.7-7.6}{\frac{11.6}{\sqrt{160}}} \\& z=2.449\end{aligned}[/tex]

For the p-value, see the z table.

Consequently, p = 0.9927.

The two-tailed nature of the test So, p = 2(1- 0.9927) = 0.0146

α = 0.1

p value< α

Thus, we disregard the null hypothesis.

Hence, at the 0.1 level, there is enough evidence to conclude that the valve does not function as intended.

Therefore, there is sufficient data to infer that the valve does not operate as intended at the 0.1 level.

Null hypothesis: H₀ : μ = 7.6

Answers

(a) n(t)=1000[tex]e^{2.08t}[/tex] track down a function that simulates the population after t hours, n(t) = n₀ert.

(a) After 1.5 hours, the population is 22646.

(c) t=1.7 will it take for there to be 15,000 bacteria

(d) The population function's graph is in the picture.

Given that,

One thousand bacteria make up a culture at the beginning. The number of bacteria is 8000 after an hour.

We have to find

(a) Track down a function that simulates the population after t hours, n(t) = n₀ert.

(a) After 1.5 hours, locate the population.

(c) How long will it take for there to be 15,000 bacteria?

(d) Draw the population function's graph.

We know that,

(a) The initial size of the culture is 1000 bacteria.    

So,  

n₀=500

The size of the culture after one hour (for t =1) is 4000 so we extract the equation:

n(1) = 8000

1000er¹=8000

e to the power of r =8

[taking logarithms both side]    

r ln e  =  ln 8                          

r=2.080

[ln e  =  1]

So, we got  

n₀=1000 and r=2.08

The function will be,

n(t)=1000[tex]e^{2.08t}[/tex]

(b) for t = 1.5

n(1.5)=1000[tex]e^{2.08(1.5)}[/tex]

22646

(c) 15000=1000[tex]e^{2.08t}[/tex]

15=[tex]e^{2.08t}[/tex]

Taking log on both sides

ln15= 2.08(t)lne

t=3.68/2.08

t=1.7

(d) Since we have have the exponential equation therefore our graph should be curve not straight line.

Also at t=1, population of bacteria is 4000

Hence the correct graph will be in picture.

Therefore,

(a) n(t)=1000[tex]e^{2.08t}[/tex] track down a function that simulates the population after t hours, n(t) = n₀ert.

(a) After 1.5 hours, the population is 22646.

Answers

The number of ways there for the 125 pages to be assigned to the four printers = 5^125 ways.

As per the question,

A 125-page document is being printed by four printers.

Each page will be printed exactly once.

There are no restrictions on how many pages a printer can print.

One of the possible combinations is that printer A prints out pages 2-50, printer B prints out pages 1 and 51-60, printer C prints out 61-80 and 86-90 and printer D prints out pages 81-85 and 91-100.

Since, there are no restrictions in printing the pages any printer cannot print even a single page and any printer can print all 125 pages. To print 100 pages we have four printers.

⇒ Number of possible ways a single paper can be assigned to the four printers = 4 ways

⇒ Number of possible ways 125 pages can be assigned to the four printers

=  5 × 5 × 5 × 5 .................... 5 ( a total of 125 terms )

=     ways.

Therefore, In   ways we can assign 125 pages to four printers with no restrictions.

Answers

Using trigonometry identities, we know that the polar form of  -9-9√3i is (D) 18 (cos(4π/3) + isin(4π/3)).

What are trigonometric identities?

Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions.

There are numerous distinctive trigonometric identities that relate to a triangle's side length and angle.

So, we have -9 - 9√3i:

This quantity has a modulus.

|-9 - 9√3 i| = √((-9)² + (-9√3)²) = √324 = 18

And argument θ to the effect:

tan(θ) = (-9√3) / (-9) = √3

We anticipate that will be between -π and -π/2 radians since -9-9√3i lies in the third quadrant of the complex plane, so that:

θ = arctan(√3) - π = π/3 - π = -2π/3

The polar form is then:

18 (cos(-2π/3) + i sin(-2π/3))

And since -2π/3 is the same angle as 2π - 2π/3 = 4π/3, the right answer is: 18 (cos(4π/3) + i sin(4π/3))


Therefore, using trigonometry identities, we know that the polar form of  -9-9√3i is (D) 18 (cos(4π/3) + isin(4π/3)).

Answers

The box's dimensions that reduce the overall cost of the materials are as follows:

L = W = 16 cm

H = 32 cm

Given,

What is the dimensions of the rectangle?

A rectangle has two dimensions: a length and a width that are both perpendicular to it. The interior of an oval or a triangle also has two dimensions.

Here,

We've got

Volume = 512 cm3 L* W * H

Sides of the box cost = 1 cent/cm²

Top and bottom cost 2 cent/cm²

Then,

Box dimensions that reduce the overall cost of materials used

We are aware of

L× W × H = 512 cm³

Where,

L stands for length, W for width, and H for height.

So, when we reduce the cost function

C(L, W, H) = (1) 1 H + (2) 1 (L + W)

Thus insert H.

Replacing H with 512/LW yields,

C(L, W) = 512(1/L, 1/W), plus 2LW

So

When both partial derivatives are 0, there will be a minimum cost.

512/L2 - 2W = dC/dL = 0

So

512/W2 - 2L = 0 for dC/dW.

L = 256/W²

Now

The answer to the aforementioned equation is

L = W = (256)⁻³ = 16cm

And

H = 512/16 = 32

H = 32 cm

Consequently, the box's measurements that reduce the overall cost of the materials utilized are:

L = W = 16 cm

H = 32 cm
