james went out for a long walk . He walked 3 2/5 of the mile. then he sat down to take rest . After that he walked 5/7 of a mile. how far did he walk together

Answers

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.

a mean of 3 out 5 students request for tomato sauce with their meal in a canteen.a random sample of 8 students is selected.what is the probability that less than 4 students request for tomato sauce with their meal​

Answers

Answer:

this answer is you listen

by the Rishabh

Step-by-step explanation:

mean of 3 out of 5 students

x 3 and 5 product of means product of extreme 3 and 4 is product of means 5 and 8 is the product of extreme x and your answer is coming follow the Rishabh

The probability of less than 4 students asking for tomato sauce along with their meal would be:

0.738

Given that,

Mean of the students asking for tomato sauce = 3/5

No. of random samples collected = 8 students

Given that,

Less than 4 = 0, 1, 2, 3

Let x be the number of students who ask for tomato sauce with their meal.

So,

[tex]P(x < 4) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)[/tex]

P(x = o) = [tex]C^{0} _{8} ( 1 - 3/5)^8 = 0.0007[/tex]

P(x = 1) = [tex]C^{1} _{8} ( 3/5) (1 - 3/5)^7 = 0.0079[/tex]

P(x = 2) = [tex]C^{2} _{8} (3/5)^2 ( 1 - 3/5)^6 = 0.0413[/tex]

P(x = 3) = [tex]C^{3} _{8} (3/5)^2 ( 1 - 3/5)^5 = 0.1239[/tex]

Using binomial distribution,

[tex]P(x< 4) = 0.0007 + 0.0079 + 0.0413 + 0.1239[/tex]

[tex]= 0.738[/tex]

Thus, 0.738 is the correct answer.

Exercise 3.29. In a school there are four kindergarten classes, with 21, 24, 17 and 28 students. We choose one of the 90 kindergarten students randomly, and denote the number of students in her class by X. Find the expectation and variance of X.

Answers

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

The absolute value of a number is 16. What is this number? Select all that apply.
A. 16
B. -1/16
C. 61
D. 1/16
E. -16

Answers

Answer:

-16 and 16 so A and E

Step-by-step explanation:

The positive version of -16 is 16

the correct answers are A) 16 and E) -16. Both 16 and -16 have an absolute value of 16, as they are equidistant from zero on the number line.

To find the number whose absolute value is 16, we can consider both the positive and negative values that satisfy this condition.

The absolute value of a number represents the distance of that number from zero on the number line. Therefore, any number that is 16 units away from zero can be the answer.

In this case, the correct answers are A) 16 and E) -16. Both 16 and -16 have an absolute value of 16, as they are equidistant from zero on the number line.

Options B) -1/16, C) 61, and D) 1/16 are not correct answers as they do not have an absolute value of 16.

Find the equation of a line that passes through the point (2,-5) and is perpendicular to the y-axis. Do not put any spaces in your answer.

Answers

Answer:

y=-5

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

Write an equation for the line that passes through (- 3, 5) and is parallel to y = - 6x + 1.

Answers

Answer:

y-5 = -6(x+3) OR y = -6x-13

Step-by-step explanation:

Let's use slope-intercept form to solve this problem.

Slope intercept form is the following:

y-y1 = m(x-x1)

x1 and y1 are given by the point in the problem.

x1 = -3, y1 = 5.

m is given by the equation in the problem. Lines that are parallel have the same slope. Thus,

m = -6.

If we plug these values into the equation for slope intercept form, we get the following:

y-5 = -6(x-(-3)) which becomes y-5 = -6(x+3)

This is an acceptable answer to the problem. However, point-slope form is also a way it can be written.

y-5 = -6x-18

y = -6x-13

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

y = 4x - 9

y = x - 3

Step 2: Solve for x

Substitute in y:                              4x - 9 = x - 3Subtract x on both sides:             3x - 9 = -3Add 9 to both sides:                     3x = 6Divide 3 on both sides:                x = 2

Step 3: Solve for y

Define:                              y = x - 3Substitute in x:                 y = 2 - 3Subtract:                           y = -1

An airplane flying with the wind takes 2 hours to travel a distance of 360 miles.

The return trip takes 3 hours flying against the wind.

What is the speed of the airplane in still air and how fast is the wind blowing?

Answers

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
