The number of children studying in different schools of kanpur is 6,45,55,587 . If the number of boys is 4,55,25,400, find the number of girls.

Answers

Answer:

19030187 girls

Step-by-step explanation:

Total number of children = 6,45,55,587

number of boys =4,55,25,400

Number of girls= (Total number of children ) - (number of boys )

= (6,45,55,587)-(4,55,25,400)

= 19030187 girls

The number of girls. Is 19030187

A parachutist's speed during a free fall reaches 50 meters per second. What is this speed in feet per second? At this speed, how many feet will the parachutist
fall during 5 seconds of free fall? In your computations, assume that 1 meter is equal to 3.3 feet. Do not round your answers.

Answers

Answer:

speed of parachutists will be 50×3.3= 165 feet per second.

Step-by-step explanation:

hence distance traveled = speed × time taken

=165×5

=825 feet

Using the tables as experimental data, determine whether it is more likely for a new food establishment to succeed and earn up to $25,000, or whether it is more likely for a new financial establishment to succeed and earn profits in either the $25,000-50,000 range or the $50,000-75,000 range, and how much more likely the one situation is than the other. Express all probabilities as percentages to two decimal places, and express differences by number of percentage points (for example, 23% is 5 percentage points greater than 18%). a. The situation involving the financial establishment has a probability 11.14 percentage points higher than the situation involving the food establishment. b. The situation involving the financial establishment has a probability 12.03 percentage points higher than the situation involving the food establishment. c. The situation involving the food establishment has a probability 2.08 percentage points higher than the situation involving the financial establishment. d. The situation involving the food establishment has a probability 2.36 percentage points higher than the situation involving the financial establishment.

Answers

More info? i don’t understand more information

The situation involving the food establishment has a probability of "2.08 % " points higher than the situation involving the financial establishment

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The question is incomplete, as the required table which is not given.

we have the following parameters:

The probability that the establishment earns up to $25k = 10.59%

The probability that the establishment earns between $25k - $50k or $50k - $75k = 8.56%

Using the above values, the difference in the probabilities are;

d = 10.59% - 8.56

d = 2.03%

Hence, the true statement about the probability is option (d)

Answers

Answer:

y = 1x - 5

Step-by-step explanation:

We will use the slope equation for this: y = mx + b

y is our output/answer

m is our slope, or the rate of change

x is our x coordinate. For example, in (3,2) x would be 3.

b is our y intercept, or where the line passes through the y axis.

Knowing this, we can fill out the blanks.

when we look at one point on the grid, and then find the next closest number from the point we chose, we can see that the slope is 1 so we now have: y = 1x + b

to find b, we find where the line passes over the y axis which on our grid is -5. Normally we would write: y = 1x + 5 Since we have a negative 5 or -5, we will change the + to a -

This means we write y = 1x -5.

Answer:

x =5

Step-by-step explanation:

2x+x-5 =x+5

Combine like terms

3x - 5 = x+5

Subtract x from each side

3x-x-5 = x+5-x

2x -5 =5

Add 5 to each side

2x-5+5 = 5+5

2x = 10

Divide by 2

2x/2 = 10/2

x =5

Answer:

x = 5

Step-by-step explanation:

2x + x - 5 = x + 5

combine like term

3 x - 5 = x + 5

subtract x from 3x

3x - x - 5 = 5

2x - 5 = 5

add 5 to 5 , we get

2x = 5 + 5

2x = 10

divide ➗ 10 by 2

x = 10/ 2

x = 5

Answers

Answer:

B., E.

Step-by-step explanation:

what was the difficulty ? this is just to understand the movement of a thrown rock.

what happens, when you throw a rock through the air ? it will first move up a little bit, reaches a maximum height, and then drops down again.

that is what the graphic shows.

so, can A. be correct ? no. as we move from 0 seconds to the right (time passes) the height of the rock increases first (before decreasing again later on).

can C. be correct ? no, it would mean that the function would look the same on both sides of the x-axis. this is clearly impossible.

can D. be correct ? no, nowhere in the graph is the height (= the functional value, the y to the x) negative.

can F. be correct ? no, we clearly see the maximum height at 1.5 seconds. at 3 seconds the height is actually at its minimum.
