The equation to describe the relationship between the height of the plant and the number of weeks is

y = x + 5

Given,

The height of the plant = x

The number of weeks = y

The height of plant at 6th week = 11 inches

The height of plant at 8th week = 13 inches

The height of plant at 10th week = 15 inches

We have to find the equation to describe the relationship between the height of the plant and the number of weeks.

Lets see,

x = 6 and y = 11, y – x = 11 – 6 = 5

x = 8 and y = 13, y – x = 13 – 8 = 5

x = 10 and y = 15, y – x = 15 – 10 = 5

That is,

y – x = 5.

y = x + 5

The domain of a function is the set of x values the function uses as inputs; from a graph the domain is the x-values that the graph take on the x-axis; in this case, since we have an infinite amount of x-valeus the function uses we will write the domain as an interval. The domain is:

Similarly, the range is the set of values the function takes on the y-axis, from the graph we notice that the range is:

X₁: science GPA for those who left their profession after graduation

X₂ science GPA for those who remained in their profession after graduation.

The working hypothesis is that the GPA of those who stayed is higher than those who left.

Which is the same as saying that the GPa of those who left is less than those who stayed.

μ₁ represents the population mean of the science GPA of those who left.

μ₂ represents the population mean of the science GPA of those who remained.

Part one

You can express the working hypothesis as follows:

The hypothesis does not include the equal sign, so this hypothesis can be considered as the alternative hypothesis.

The null hypothesis of this test will be the complement of the alternative hypothesis, and always carries the equal sign within. So if the alternative hypothesis states that "the mean of the leavers is less than the mean of the stayers", then the null hypothesis will be that "the mean of the leavers is greater than or equal to the mean of the stayers" you can symbolize this as:

Since the null hypothesis carries the equal sign you can also write it as:

Both options are equally valid.

So, the second answer is null hypothesis.

Part two

Considering that we are studying the population means of two normal variables and that we know the population standard deviation for both populations, the test statistic to use is the standard normal for the difference of means which is defined as follows:

Subindex 1 indicates the values corresponding to the "leavers":

X₁bar= 3.16

n₁= 103

σ₁= 0.52 → σ₁²= 0.2704

Subindex 2 indicates the values corresponding to the "stayers":

X₂bar= 3.28

n₂= 225

σ₂= 0.46 → σ₂²= 0.2116

Under the null hypothesis both population means are equal, which means that their difference is equal to zero:

If μ₁ = μ₂, then μ₁ - μ₂ = 0

Replace all values on the formula to determine the Z-value under the null hypothesis, i.e. the test statistic:

3 per thousand?

10000 ------------------------- 1000

x ------------------------ 3

x = (3 x 10000)/1000

x = 30

The answer is 30

The root mean square velocity of Neon, in m/s as required in the task content is; 18.45 m/s.

It follows from the task content that the root mean square velocity of Neon is to be determined.

Since the molar mass of Neon is; 20 while the gas constant, R = 8.314 and T = 273K.

It follows from the root mean square velocity formula that we have;

R.M.S = √(3RT/M)

R.M.S = √{(3×8.314×273)/20}

R.M.S = √340.46

R.M.S = 18.45 m/s.

Hence, the root mean square velocity of Neon, Ne under the given condition is; 18.45 m/s.

In order to solve the expression:

We operate inn such a manner that x is left alone, that is:

We have our expression 9 - 2x = 35.

In order to solve for x, we try and leave x alone, that is, we sustract 9 from both sides of the operation:

9 - 9 - 2x = 35 -9 => -2x =26

Now that we have this, we proceed to eliminate -2 from the side of x, for that we divide both sides by -2, that is:

(-2/-2)x=(26/-2) => x = -13

An equation is a collection of variables and constants. The value of p for the given equation p + 7 = −15 is p = -22 so option (A) is correct.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

The equation must be constrained with some constraints.

As per the given equation,

p + 7 = -15

Subtract both sides by 7

p + 7 - 7 = -15 - 7

p + 0 = -22

p = -22

Hence "An equation is a collection of variables and constants. The value of p for the given equation p + 7 = −15 is p = -22 so option (A) is correct".

The speed of the cyclist in miles per hour is 7.5 miles per hour. The distance covered by the cyclist in 5 hours is 30 miles.

According to the question,

We have the following information:

A cyclist rides his bike at the speed of 11 ft per second.

Now, it is given that we have to use 1 mile = 5280 ft.

So, we have:

1 ft = 1/5280 miles

We know that there 3600 seconds in 1 hour.

1 seconds = 1/3600 hour

So, we  have the speed in miles per hour:

11*(1/5280)/(1/3600)

(11*3600)/5280

7.5 miles per hour

Time taken = 5 hours

Speed = 7.5 miles per hour

Distance = speed*time

Distance = 7.5*5

Distance = 30 miles

Hence, the speed of the cyclist in miles per hour is 7.5 miles per hour. The distance covered by the cyclist in 5 hours is 30 miles.

The heighth of the cylinder if the surface area is 942 square feet is 25 feet.

From the information given, the S = 2π(25) + 2π(5h). We are to find the heighth of the cylinder if the surface area is 942 square feet.

This will be:

S = 2π(25) + 2π(5h).

2π(25) + 2π(5h) = 942

50π + 10πh = 942

(50 × 3.14) + (10 × 3.14 × h) = 942

157 + 31.4h = 942

Collect like terms

31.4h = 942 - 157

31.4h = 785

h = 785/31.4

h = 25

The height of the cylinder is 25 feet

A) Check the graph below, please. B) Horizontal translation to the left in 2 units. C) Vertical shift 4 units

1) Given that we have the function h(x) = |x+2| and g(x)= |x| + 4

A) Let's set a pair of tables, and pick 3 arbitrary values for x and then plug into each one

h(x) = |x+2|

x | y = |x+2|

-1 | 1 y =|-1 +2| = |1| = 1

0 | 2 y =|0+2| = |2| = 2

1 | 3 y =|1+2| = |1| = 1

g(x) =|x| + 4

x | y

-1 | 5

0 | 4

1 | 5

Let's plot those absolute value functions:

B) Considering the parent function f(x) =|x| we can notice that h(x) is a translation to the left, in two units. This we can see better this way:

Note that f(x) is in red, and h(x) in pink or light red.

C) Considering that f(x) = |x| we can see that g(x) = is a vertical shift 4 units up.
