Using the **normal distribution**, the **area **underneath the shaded region between the two z-scores is given by:

**C. **0.6766.

Normal Probability Distribution

The **z-score** of a** measure X** of a normally distributed variable with **mean **[tex]\mu[/tex] and **standard deviation** [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score **measures **how many standard deviations the measure is above or below the mean. Looking at the z-score table, the **p-value** associated with this z-score is found, which is the **percentile **of X.

Hence, for this problem, the **area **is the p-value of z = 0.75 subtracted by the p-value of z = -1.3.

Looking at the** z-table,** the **p-values** are given as follows:

z = 0.75: 0.7734.z = -1.3: 0.0968.

Then:

0.7734 - 0.0968 = 0.6766.

Plug these values into the equation.

b)

Evaluate h(t) at the time of maximum height. The time of maximum height is the value found in previous part.

c)

Set h(t) equal to 3 and solve for t.

3 = -16t2 + 30.4t + 5

You are asked to draw a colored marble out of a box. The are 5 red marbles, 11 blue

marbles, and 4 green marbles in the box. What is the probability of drawing a red marble

and then a green marble without replacing the first marble? Round to 3 decimal places.

### Answers

As per the question-mentioned condition, the **probability** of drawing a red marble and then a green marble without replacing the first marble, rounded to 3 decimal places will be 0.053.

As mentioned in the question statement, the box contains 5 red marbles, 11 blue marbles, and 4 green marbles and we have asked to draw two marbles out of the box, one after another.

Here, total number of marbles in the box initially before starting to draw was [tex](5+11+4)=20\\[/tex] marbles.

Therefore, **probability** of drawing a red marble in the first draw will be [tex]\frac{5}{20}=\frac{1}{4}=0.25\\[/tex].

Now, after the first draw, since it is conditioned in the question-statement that the first marble will not be replaced, then the number of remaining marbles in the box will be [tex][(5-1)+11+4)=19[/tex] marbles, 4 red, 11 blue and 4 green.

Now, the probability of drawing out a green marble will be [tex]\frac{4}{19}=0.21052=0.211[/tex].

Hence, the probability of drawing a red marble and then, a green marble without replacing the first one will be [tex](0.25*0.211)=0.05275=0.053[/tex].

Ones digit of 2 to the power of 2029?

### Answers

**Answer: 8**

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

Explanation:

Let's list out a few numbers of the form 2^n where n is some positive integer.

2^1 = 22^2 = 42^3 = 82^4 = 162^5 = 322^6 = 642^7 = 1282^8 = 2562^9 = 512

Then focus solely on the units digit of each result:

**2, 4, 8, 6**, 2, 4, 8, 6, 2, ...

We see the pattern is "**2,4,8,6**" and that pattern repeats forever. The reason why is because once we reach 6, we get back to 2 and it restarts the cycle. The pattern repeats itself every 4 values.

------------------

So we'll divide the exponent by 4 and look at the remainder (see note at the end)

2019/4 = 504 remainder 3

The remainder 3 tells us to look at the 3rd slot of the list {2,4,8,6}

**That third item is 8**

**Therefore units digit of 2^2019 is 8.**

------------------

Side note: if you get a remainder of 0, then look at slot 4. This works because 4/4 = 1 remainder 0.

In other words, think of "remainder 0" as "remainder 4".

This is given by the value of

[tex]2^{2029} \pmod{10}[/tex]

which is an integer [tex]n[/tex] between 0 and 9 such that

[tex]2^{2029} = 10m + n[/tex]

where [tex]m[/tex] is any integer.

Any power of 2 ends in an even digit, so [tex]n[/tex] must even. Write [tex]n=2n'[/tex] for integer [tex]n'[/tex]. Then

[tex]2^{2029} = 10m + 2n' \implies 2^{2028} = 5m + n'[/tex]

so now we want to find

[tex]2^{2028} \pmod 5[/tex]

We have [tex]\phi(5) = 3[/tex], where [tex]\phi(n)[/tex] is Euler's totient function, the number of primes less than or equal to [tex]n[/tex]. Then

[tex]2^{2028} \equiv 2^{3\cdot676} \equiv \left(2^{676}\right)^3 \equiv 1 \pmod 5[/tex]

by Euler's theorem, and

[tex]n'=1\implies n=2 \implies 2^{2029} = 10m + 2 \iff 2^{2029} \equiv \boxed{2} \pmod{10}[/tex]

You bike at a constant speed of 10 miles per hour. You plan to bike 30 miles, plus or minus 5 miles. Write and solve an equation to find the minimum and maximum numbers of hours you bike. Use t as your variable.

Equation:

Minimum: t =

Maximum: t =

### Answers

The **equation** for the **bike** is s = 10 · t and the **minimum** and **maximum t** are 2.5 hours and 3.5 hours, respectively.

What are the minimum and maximum biking times for a case at constant speed?

As the **bike** travels at constant **speed** (v), in miles per hour, the **traveled distance** (s), in miles, is directly proportional to the **biking time** (t), in hours. The situation can be modeled as follows:

s ± Δs = v · (t ± Δt)

**Minimum t:**

s - Δ s = v · (t - Δt)

30 - 5 = 10 · (t - Δt)

t - Δt = 25 / 10

t - Δt = 2.5

**Maximum t:**

s + Δ s = v · (t + Δt)

30 + 5 = 10 · (t + Δt)

t + Δt = 35 / 10

t + Δt = 3.5

The solution of the **inequality **x – 2x + 5 < 7 is x > -4

The equation given to us is an **inequality **equation. Basically inequality means a mathematical equation in which the sides are not equal to each other.

We will solve this equation step by step

Equation given to us is,

x – 2x + 5 < 7

On left hand side we will subtract the **coefficient **of x variable we get,

-x + 5 < 7

Then to isolate the **variable **x we will **subtract **both side by 5 and then **divide **by -1 on both the side,

That is, -x + 5 – 5 < 7 – 5

-x < 4

-x/-1 < 4/-1

x > -4 when we divide both side by minus sign the inequality sign is reversed

Hence x > -4 is the required solution of the inequality.

On a number line, the coordinates of X, Y, Z, and W are - 6, -2, 4, and 8, respectively. Find the lengths of the two segments below. Then tell whether they are congruent

XY and ZW

### Answers

If the coordinates of X, Y, Z, and W on a **number line** are - 6, -2, 4, and 8, respectively, then the lengths of the segment XY is 4 and that of the segment ZW is also 4, and hence, these two segments (XY and YZ) are indeed **Congruent** in nature.

To increase the understandability of this question, we will go ahead a visual representation of the **number line** based on the condition mentioned in the question statement, attached hereby as "Number Line (-10 to 10)".

As per the figure, we can clearly see that the line segment XY begins at (-6) on the number line and ends at (-2), i.e., Length of XY is:

[(-2) - (-6)] = 4.

Similarly, we can also see that the line segment ZW begins at (4) on the number line and ends at (8), i.e., Length of ZW is:

(8 - 4) = 4.

Also, since the lengths of both XY and ZW are same, i.e., 4 Units, they are **congruent **in nature.

**Number Line**: In elementary mathematics, a number line is a picture of a graduated straight line, with real numbers, (generally integers, both positive and negative) at equal intervals on it.**Congruent Lines:** Two line segments of equal lengths are known to be congruent.
