The complete table of values of the equation y = 3x + 5 is

x = -2, -1, 0, 1 2

y = -1  2  5   8  11

The complete question is added at the end of this solution

From the question, we have the following equation that can be used in our computation:

y = 3x + 5

From the table of values added at the end of this question, we have the following x values

x = -2, -1, 0, 1 and 2

Substitute x = -2, -1, 0, 1 and 2 in y = 3x + 5

So, we have the following representation

y = 3(-2) + 5 = -1

y = 3(-1) + 5 = 2

y = 3(0) + 5 = 5

y = 3(1) + 5 = 8

y = 3(2) + 5 = 11

So, the complete table of values is

x = -2, -1, 0, 1 2

y = -1  2  5   8  11

The value of n in the given equation is 1.

Define Algebraic Expression

In mathematics, an expression that includes variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.)

Given equation,

-1/2 (2n + 4) + 6 = -9 + 4(2n + 1)

Now, solve for n

first, solve the brackets

-1/2 * 2n + (-1/2) * 4 + 6 = -9 + 4*2n + 4 * 1

-n - 2 + 6 = -9 + 8n + 4

Solve the constants on both the sides,

-n + 4 = 8n - 5

Now, take out n value one side and constant terms other side

-n - 8n = -5 - 4

-9n = -9

Cancel out -9 from both the sides,

n = 1

Hence, the value of n in the given equation is 1.

The number of Canadian dollars your 212 US dollars became is 264.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, you have saved $212 to take for spending money in vacation.

Here, 25 Canadian dollars is equivalent to $20.08 US dollars

Now, number of US dollars = 212/20.08

= 10.56

So, 25 Canadian dollars = 25× The number of US dollars

= 25×10.56

= 264 Canadian dollars

Step-by-step explanation:

the total angle of a triangle always adds up to 180

z=34

Answer:

6x-3=15

Step-by-step explanation:

The equivalent linear equation to the line 3x + 4y = 15 is the one in the first option:

y = (15 - 3x)/4

Here we have the following linear equation:

3x + 4y = 15

And we want to find an equivalent linear equation where y is isolated in the left side of the equation. So let's isolate the variable.

If we subtract 3x in both sides of the linear equation we will get:

3x + 4y - 3x = 15 - 3x

4y = 15 - 3x

Now we can divide both sides by 4, so we will get:

4y/4 = (15 - 3x)/4

y = (15 - 3x)/4

This is the equation in option 1, so we conclude that the correct option is the first one.

4x is 25 percent of 16x.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Let the percentage be P.

Now,

P% of 16x = 4x

P/100 x 16x = 4x

P/100 = 4x/16x

P/100 = 1/4

P = 100/4

P = 25

This means,

25% of 16x is 4x.

We can cross-check.

= 25% of 16x

= 1/4 x 16x

= 4x

Thus,

25 percent of 16x is 4x.

Answer: Range

Step-by-step explanation:

Approximately 95% of men must duck when walking through a door that is 72 inches high. Approximately 5% of women must duck when walking through the door. The door height that would allow at least 95% of men to walk through the door without ducking is 74 inches.

The mean height of men is 69.0 inches and the standard deviation is 2.8 inches, while the mean height of women is 63.6 inches and the standard deviation is 2.5 inches.

(a) To find the percentage of men who must duck when walking through a door that is 72 inches high, we first need to find the percentage of men whose height is less than 72 inches.

The height of the door is 72 inches, which is 3 inches above the mean height of men.

Since the standard deviation is 2.8 inches, this means that approximately 95% of men are within 2.8 * 2 = 5.6 inches of the mean height.

Therefore, approximately 95% of men are between 69.0 - 5.6 = 63.4 inches and 69.0 + 5.6 = 74.6 inches tall.

If the height of the door is 72 inches, approximately 95% of men must duck when walking through the door.

(b) To find the percentage of women who must duck when walking through a door that is 70 inches high, we first need to find the percentage of women whose height is less than 70 inches.

The height of the door is 70 inches, which is 6.4 inches above the mean height of women.

Since the standard deviation is 2.5 inches, this means that approximately 95% of women are within 2.5 * 2 = 5 inches of the mean height. Therefore, approximately 95% of women are between 63.6 - 5 = 58.6 inches and 63.6 + 5 = 68.6 inches tall.

If the height of the door is 70 inches, approximately 5% of women must duck when walking through the door.

(c) To find the door height that would allow at least 95% of men to walk through the door without ducking, we need to find the height that is within 2 standard deviations of the mean height of men.

Since the standard deviation is 2.8 inches, this means that approximately 95% of men are within 2.8 * 2 = 5.6 inches of the mean height.

Therefore, the door height that would allow at least 95% of men to walk through the door without ducking is 69.0 + 5.6 = 74

The z score that has 70.54% of the distribution area is 9.92

The z-score is a numerical measurement used in statistics to refer to how much a given value differs from the standard deviation.

For the random variable x, the z-score is;

z = (x - 11)/2

therefore, 70.54% of the area under the curve lies to the right of x,

then the area to the left of x is;

100 - 70.54 = 29.46%

From the standard table, a z-score of -0.54 will yield an area of 29.46% to the left of x.

Therefore, we get;

(x - 11)/2 = -0.54

x - 11 = -0.54(2)

The length of the side a is 112.1664 cm.

The ratios of a triangle's side lengths to each of its opposite angles are related by the law of sines. There is no change in this ratio for the three sides or the opposing angles.

The Law of sines;

Sin A / a = Sin B / b = Sin C/ c

Here, we have two angles 35° and 25° and a side b = 5 ft

Now, sin35°/5 = sin25°/a

a = (0.42) x 5 / (0.57)

a = 3.68
