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.

Which means that option C is correct.

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].

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]

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

Answer:

There must be a problem with the question because I keep getting 14/4

Step-by-step explanation:

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.

What is the missing information?

The right triangle is missing, which shows that:

The side adjacent to the angle of 58º is of 6 mi.The side opposite to the angle of 58º is of BC.

Hence, we can apply the relations in the right triangle given to find the length of side BC, which is the distance from point B to point C.

What are the relations in a right triangle?

The relations in a right triangle are given as follows:

The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.

Hence:

tan(58º) = 6/BC

BC = 6/tan(58º)

Step-by-step explanation:

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.
