Step-by-step explanation:

The parallel lines are r and s.

Parallel lines are those lines that are equidistance from each other and never intersect each other.

Given that;

There are 4 lines ae shown in figure.

Now,

Since, There are 4 lines ae shown in figure.

We know that,

Parallel lines are those lines that are equidistance from each other and never intersect each other.

And, Here p and s are intersect at a point.

Lines q and r are intersect at a point.

Lines p and r are intersect at a point.

And, Lines r and s are not intersect at any point and equidistance from each other.

Thus, The lines r and s are parallel lines.

Answer: still air is 150mph. The wind speed is 30mph.

Step-by-step explanation:

X=speed of the plane, Y=speed of the wind.

360/2hours=180

360/3hours=120

2x=180+120

2x=300

X=150

The airplane in still air is 150mph

Add together

X+y=180

150+y=180

Y=180-150

Y=30mph

The wind speed is 30mph

The smallest possible whole number length for the third side is 7

Case 1

1st + 2nd > 3rd

5 + 11 > 3rd

16 > 3rd

3rd length < 16

Case 2

1st + 3rd > 2nd

5 + 3rd > 11

3rd > 11 - 5

3rd > 6

Thus, we have

6 < 3rd length < 16

Since the 3rd length is greater than 6, then the smallest possible length for the 3rd side is 7

Answer:

[tex]\displaystyle \mathbf{\frac{5}{(c+4)}}[/tex]

Step-by-step explanation:

Division of Rational Expressions

When dividing two rational expressions like f(c) / g(c), it's usually easier to multiply the numerator by the reciprocal of the denominator: f(c) * (1/g(c)). The reciprocal is just flipping the numerator and the denominator.

Let's find the following division:

[tex]\displaystyle \frac{\frac{c^2-64}{3c^2+26c+16}} {\frac{c^2-4c-32}{15c+10}}[/tex]

First, we factor the polynomials where possible.

[tex]c^2-64 = (c-8)(c+8)[/tex]

[tex]3c^2+26c+16=(3c+2)(c+8)[/tex]

[tex]c^2-4c-32=(c-8)(c+4)[/tex]

[tex]15c+10=5(3c+2)[/tex]

Substituting:

[tex]\displaystyle \frac{\frac{c^2-64}{3c^2+26c+16}} {\frac{c^2-4c-32}{15c+10}}=\frac{\frac{(c-8)(c+8)}{(3c+2)(c+8)}} {\frac{(c-8)(c+4)}{5(3c+2)}}[/tex]

Multiplying by the reciprocal of the denominator:

[tex]\displaystyle \frac{\frac{c^2-64}{3c^2+26c+16}} {\frac{c^2-4c-32}{15c+10}}=\frac{(c-8)(c+8)}{(3c+2)(c+8)}\cdot \frac{5(3c+2)}{(c-8)(c+4)}[/tex]

Simplifying by (c+8)(3c+2)(c-8):

[tex]\displaystyle \frac{\frac{c^2-64}{3c^2+26c+16}} {\frac{c^2-4c-32}{15c+10}}=\frac{5}{(c+4)}[/tex]

Answer:

Answer:

Expected mean = 23.2159

Variance = 15.89

Step-by-step explanation:

Given that :

Number of kindergarten students (X) :

21 + 24 + 17 + 28 = 90

P(X):

21/ 90 = 0.233

24/90 = 0.2667

17/90 = 0.1889

28/90 = 0.3111

X : ____ 21 ____24 _____ 17 ______ 28

P(x) : _ 0.233 _ 0.2667 __ 0.1889 __ 0.3111

E(X) = Σ[(p)*p(x)]

(21 * 0.233) + (24 * 0.2667) + (17 * 0.1889) + (28 * 0.3111) = 23.2159

Var(X) : Σ(x²*p(x)) - E(x)²

x² * p(x) = (21^2 * 0.233) + (24^2 * 0.2667) + (17^2 * 0.1889) + (28^2 * 0.3111) - 23.2159^2

554.8667 - 538.97801281

= 15.88868719

Step-by-step explanation:

Equation of the line

Lines can be expressed in several forms. The slope-intercept form of the line is:

y = mx + b

Where m is the slope of the line and m is the y-intercept.

If the line is perpendicular to the y-axis, then it's a horizontal line. Horizontal lines have slope m=0, thus, the equation is:

y = b

To find the value of b, just substitute the given point:

-5=b

The equation of the line is:

y=-5

Answer:

Altogether James walked [tex]4\frac{4}{35}[/tex] miles.

Step-by-step explanation:

The question involves mixed fractions. Mixed fractions are first converted into proper fractions and then any operation can be performed on them.

Given

Distance of first walk = [tex]3\frac{2}{5}[/tex] of a mile

Distance of second walk = 5/7

In order to find how much he walked altogether, we have to find the sum of both fractions.

[tex]Total\ distance = 3\frac{2}{5}+\frac{5}{7}\\= \frac{17}{5}+\frac{5}{7}\\=\frac{17*7}{5*7} + \frac{5*5}{7*5}\\=\frac{119}{35} + \frac{25}{35}\\=\frac{119+25}{35}\\=\frac{144}{35}\\=4\frac{4}{35}[/tex]

Hence,

Altogether James walked [tex]4\frac{4}{35}[/tex] miles.
