Answer:

3

Step-by-step explanation:

Answer:

Angle M and N is 45 degrees, and the length of NP is approximately 6 cm

Step-by-step explanation:

With angle P being 90 degrees. The angles of M and N, must add up to 90 degrees as well.

 *triangles add up to a total of a 180 degrees, (180 - 90 = 90)

   9 ÷ 2 = 45

   So: ∠M = 45° and ∠N = 45°

To find the length of NP, use the pythagorean theorem.

a² + b² = c²

a = MP = 5

b = NP = x

c = MN = 7.8

(5)² = 25

(7.8)² = 60.48

25 + x² = 60.48

x² = 60.48 - 25

x² = 35.84

x = √35.84

x = 5.986 = 5.99

NP = 5.99 = 6

Answer:

The test statistic is z = -2.11.

Step-by-step explanation:

Before finding the test statistic, we need to understand the central limit theorem and subtraction of normal variables.

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Subtraction between normal variables:

When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.

Group 1: Sample of 35, mean of 1276, standard deviation of 347.

This means that:

[tex]\mu_1 = 1276, s_1 = \frac{347}{\sqrt{35}} = 58.6537[/tex]

Group 2: Sample of 35, mean of 1439, standard deviation of 298.

This means that:

[tex]\mu_2 = 1439, s_2 = \frac{298}{\sqrt{35}} = 50.3712[/tex]

Test if there is a difference in productivity level.

At the null hypothesis, we test that there is no difference, that is, the subtraction is 0. So

[tex]H_0: \mu_1 - \mu_2 = 0[/tex]

At the alternate hypothesis, we test that there is difference, that is, the subtraction is different of 0. So

[tex]H_1: \mu_1 - \mu_2 \neq 0[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{s}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis and s is the standard error.

0 is tested at the null hypothesis:

This means that [tex]\mu = 0[/tex]

From the two samples:

[tex]X = \mu_1 - \mu_2 = 1276 - 1439 = -163[/tex]

[tex]s = \sqrt{s_1^2+s_2^2} = \sqrt{58.6537^2+50.3712^2} = 77.3144[/tex]

Test statistic:

[tex]z = \frac{X - \mu}{s}[/tex]

[tex]z = \frac{-163 - 0}{77.3144}[/tex]

[tex]z = -2.11[/tex]

The test statistic is z = -2.11.

Answer:

335 mm²

Step-by-step explanation:

This will be so easy, that you can do it in the future by yourself!

Okay let's start by splitting this figure, the easiest way seems to be by cutting off that little part, you know what just let me show a picture.

Okay you shuold be able to see the picture, so the small square has an area of 20, since 5 times 4 is 20 mm! The larger square has an area of 315!

How did I find this? Take that small 10mm in the side and add it to 5mm, that would be 15. 15 times the bottom the width, it would be 15 * 21. 15 times 21 is equal to 315.

Now, we add both those areas together, to get ourselves a nice little 335 mm²

I hope that helped, have a great day!!

Answer:

C

Step-by-step explanation:

It is determined that no subscriber had been selected in the sample more than once the sample had to have been selected without replacement.

A sample is a subset of data drawn from a larger population by a researcher using a predetermined selection process. These components are referred to as sample points, sampling units, or observations.

If it is determined that no subscriber had been selected in the sample more than once, this means that each subscriber was only included once in the sample. This can only occur if the sample was selected without replacement, meaning that each subscriber was selected once and only once from the population frame.

Therefore, the correct answer is C. the sample had to have been selected without replacement.

Answer:

  5.04 seconds

Step-by-step explanation:

Assuming the ball is in the air until f(x) = 0, we want to find x such that ...

  0 = -5x² +25x +1

  0 = x² -5x -1/5 . . . . . divide by -5

  1/5 = x² -5x . . . . . . . add 1/5

  1/5 +25/4 = (x² -5x +25/4) . . . . complete the square

  129/20 = (x -5/2)² . . . . . . . . . . write as a square

  x = 5/2 +√(129/20) ≈ 5.039685 . . . . square root, add 5/2

The ball stays in the air about 5.04 seconds.

Answer:

16(6g + 5f)

Step-by-step explanation:

To factor the equation:

96g + 80f

16(6g + 5f)

=======================================================

Work Shown:

A = P*(1+r/n)^(n*t)

1000 = 500*(1+0.029/4)^(4*t)

1000 = 500*(1.00725)^(4*t)

1000/500 = (1.00725)^(4*t)

2 = (1.00725)^(4*t)

log(2) = log( 1.00725^(4*t) )

log(2) = 4*t*log( 1.00725 )

4*t*log( 1.00725 ) = log(2)

t = log(2)/( 4*log( 1.00725 ) )

t = 23.9881659971072 The value is approximate

t = 24 when rounding to the nearest full year

Answer:

А . Marcos made an incorrect conversion from centimeters to inches. The correct price is $23.03.

Step-by-step explanation:

Given that,

Length of fabric = 1.3 meters

We know that,

1 m = 100 cm

⇒1.3 m = (1.3)×100 = 130 cm

⇒1.3 m = 130 cm

Now,

We know that

1 inch = 2.54 cm

and

1 cm = 0.3937 inches

⇒130 cm = (130)×(0.3937) inches

               = 51.181 inches

⇒130 cm = 51.181 inches

Now,

Given that,

Cost of 1 inch = $0.45

⇒Cost of 51.181 inches = $(51.181)×(0.45)

                                     = $ 23.03

∴ we get

The cost of fabric = $23.03

and

The correct option is - А . Marcos made an incorrect conversion from centimeters to inches. The correct price is $23.03.
