Answer:

Equation 2: x - 2y = 1

Step-by-step explanation:

The equations easiest to use substitution are the ones that have the variable multiplied by one, as in the case of Eq. 2 where x is 1x, so if you substitute a zero for x, we know that y has to be -1/2 for the equation to be true.  Furthermore, if you substitute a 0 for y you automatically know that x = 1.

If you try to substitute anything for x in equation 1, let's say x = 1, you still have to multipy by 3, then the rest of the problem would be more steps.

Answer:

4(9a-4)

Step-by-step explanation:

36a - 16

We can factor 4 from each expression.

4*9a - 4*4

4(9a-4)

Answer:

First what you want to do is find what fraction is equal to 1/4 and has a denominator of 20.

The way you can find this is by taking 1/4 and seeing how many times the denominator or 4 will go into 20.

4 * 5 = 20

Since 4 times 5 is 20, we will multiply 5 to the numerator of the fraction to.

1 * 5 = 5

So 5/20 is = to 1/4

x = 5

Now the question says, " x less thsn the denominator" so we just need to find how much less is 5 compared to 20.

20 - 5 = 15

The numerator has a value, "15 less than the denominator."

The rejection region is not given in the question, so we cannot determine the type of error that can occur when the true survival rate is 50%.

However, we can calculate the probability of making a Type I error (rejecting the null hypothesis when it is actually true) and a Type II error (failing to reject the null hypothesis when it is actually false) for a given rejection region.

Assuming a significance level of 0.05, the rejection region for a one-tailed test of whether the true survival rate is greater than 40% is  with 19 degrees of freedom.

If the true survival rate is actually 50%, the probability of making a Type I error (rejecting the null hypothesis that the true survival rate is 40%) is 0.05, which is the significance level.

The probability of making a Type II error (failing to reject the null hypothesis that the true survival rate is 40% when it is actually 50%) depends on the true survival rate and the sample size. A larger sample size would decrease the probability of making a Type II error.

Since the product of the slope is -1, hence the lines are perpendicular

Two lines are known to be parallel if they have the same slope while if two lines are perpendicular if the product of the slope is -1

Given the coordinates of line 1 passing through (0, 6) and (6, 4), the slope is given as;

Slope = 4-6/6-0
Slope = -2/6
Slope = -1/3

Similarly for the coordinate points (-1, -7) and (1, -1).

Slope = -1+7/1+1
Slope of line 2 = 6/2

Slope = 3

Take the product of the slopes

Slope = -1/3 * 3
slope = -1

Answer:

a) La regla general de sucesión de esta lista es: \(a_{i} = -2\cdot i\), \(i\in \mathbb{N}_{O}\).

b) La regla general de sucesión de esta lista es: \(a_{i} = -2\cdot i +1\), \(i\in \mathbb{N}_{O}\).

Step-by-step explanation:

Debemos recordar que toda sucesión natural es un conjunto discreto al estar conformado por números enteros no negativos, cuyos elementos observan una función de la forma:

\(a_{i} = a\cdot i + b\), \(i\in \mathbb{N}_{o}\) (Eq. 1)

Donde:

\(a_{i}\) - i-ésimo elemento de la sucesión, adimensional.

\(a\) - Tasa de incremento entre dos elementos consecutivos, adimensional.

\(b\) - Valor del elemento inicial de la sucesión (i = 0), adimensional.

Para la tasa de incremento se cumple que:

\(a = a_{i+1}-a_{i}\), \(i \in \mathbb{N}_{O}\) (Eq. 2)

Ahora, procedemos a deducir la regla general de sucesión de cada lista:

a) 0, -2, -4, -6, -8,...

El valor del elemento inicial de la sucesión es:

\(b = 0\)

La tasa de incremento es:

\(a = -2 - 0\)

\(a = -2\)

La regla general de sucesión de esta lista es: \(a_{i} = -2\cdot i\), \(i\in \mathbb{N}_{O}\).

b) +1, -1, -3,-5, -7,...

El valor del elemento inicial de la sucesión es:

\(b = 1\)

La tasa de incremento es:

\(a = -1-1\)

\(a = -2\)

La regla general de sucesión de esta lista es: \(a_{i} = -2\cdot i +1\), \(i\in \mathbb{N}_{O}\).

Answer:

A) 3.996 inches

B) 0.01

C) option B

Step-by-step explanation:

Note: The diameter of the lid is between : 3.95 and  4.05

A) calculate the supplier set mean diameter

std = 0.02 inch

P( x < 3.95 ) = 1% = 0.01

= P ( Z < \((\frac{3.95 - u }{0.02})\) ) = P ( Z < -2.3263 ) = 0.01

therefore :

\((\frac{3.95 - u }{0.02})\)  = -2.3263

hence : u = 3.996 inches ( mean diameter )

B) At mean diameter = 3.98 calculate the value of std

P ( X < 3.95 ) = 0.01

= P ( Z < \(( \frac{3.95-3.98 }{std } )\) )  = P ( Z < -2.3263 ) = 0.01

therefore

\(( \frac{3.95-3.98 }{std } )\) = -2.3263

hence std = 0.01 inch

C) option B is preferable because its mean diameter is smaller and  the percent of lids too large to fit is considered more carefully using option B

172 cm is approximately 5 feet and 7.72 inches.

To convert from cm to feet and inches, you can use the conversion factor 1 cm = 0.393701 inches. To convert 172 cm to inches, you would multiply 172 by 0.393701, which gives you 67.716566 inches.

Then, you can divide the total number of inches by 12 to get the number of feet, which in this case is 5.6430472 feet. Finally, you can subtract the number of feet from the total number of inches to get the remaining inches, which in this case is 7.716566 inches.

Therefore, 172 cm is equivalent to 5 feet and 7.72 inches.

Step-by-step explanation:

The given data is,

→ the ratio of cups of water to cups of milk in a recipe is 1 to 5

Now we have to,

→ find three ratios equivalent to the ratio

Then the ratios will be,

→ 1 (×2) : 5 (×2)

= 2 : 10

→ 1 (×3) : 5 (×3)

= 3 : 15

→ 1 (×4) : 5 (×4)

= 4 : 20

Thus, 2 : 10, 3 : 15 & 4 : 20 are the ratios.

The estimated total number of heartbeats in an average lifetime of 68.4 years is 2.9 billion heartbeats. The maximum number of 91 kg people that can safely occupy an elevator is 10 people.  The diameter of human hair is 0.000056 meters.

(a) To estimate the total number of heartbeats in a lifetime, we multiply the heart rate (69.2 beats/minute) by the number of minutes in a year (60 minutes/hour * 24 hours/day * 365.25 days/year) and then multiply by the number of years in a lifetime (68.4 years). The calculation is: 69.2 beats/minute * 60 minutes/hour * 24 hours/day * 365.25 days/year * 68.4 years ≈ 2,886,699,648 beats. Therefore, the estimated total number of heartbeats in an average lifetime is approximately 2.9 billion heartbeats.

(b) To determine the maximum number of 91 kg people that can occupy the elevator, we divide the maximum mass the elevator can hold (1 metric ton or 1000 kg) by the mass of each person (91 kg). The calculation is: 1000 kg / 91 kg ≈ 10.98. Since we can only have whole numbers of people, the maximum number of people that can safely occupy the elevator is 10.

(c) To express the diameter of a human hair in meters, we convert the given diameter of 56 μm to meters by dividing by 1 million (since 1 μm = 1/1,000,000 meters). Therefore, the diameter of human hair is approximately 0.000056 meters.

(d) To convert 74 miles per hour to meters per second, we multiply the given value by the conversion factor 1609 meters/mile and divide by 3600 seconds/hour. The calculation is 74 miles/hour * 1609 meters/mile / 3600 seconds/hour ≈ 33.12 meters/second. Therefore, 74 miles per hour is approximately equal to 33.12 meters per second.
