Cole has 8 pieces of string that are 5 yards each. He uses 4 pieces that are each 5 feet long.

1 answer:

4 0

100 feet
To find the total length of the entire string you multiply 8 times 5 and get 40.
To convert into feet multiply by 3 and get 120 feet.
To find the total amount of string he uses, multiply 4 times 5 and get 20. It is already in feet.
Next you subtract 120 - 20 and get 100 feet, the total amount of string he has left.

What is the equation of the following line written in slope-intercept form?

nasty-shy [4]

SOLUTION:

To begin with, let's establish that the formula of this line is in slope-intercept form as follows:

y = mx

The formula for this line isn't:

y = mx + b

This is as this line doesn't have a y-intercept ( b ) as it passes through the origin instead. This means that ( b ) would be rendered useless in this formula as it would just bring us back to the y = mx formula as displayed below:

y = mx + b
y = mx + 0
y = mx

Moving on, for ( m ), we need to find the gradient of the line as displayed below:

m = gradient
m = rise / run
m = 10 / 2
m = 5

Now, we must simply substitue ( m ) into the formula in order to obtain the equation for this line as displayed below:

y = mx
y = 5x

Therefore, the answer is:

A. y = 5x

Can someone help me?

Amanda [17]

Answer:

y = 250x + 1000

Step-by-step explanation:

we know, it is a linear function.

so, y = ax + c

we have multiple data points all on the line.

(4,2000)

2000 = a×4 + c, => c = 2000 - a×4

(7,2750)

2750 = a×7 + c

=> 2750 = a×7 + 2000 - a×4 = a×3 + 2000

=> 750 = a×3

=> a = 250

=> c = 2000 - 250×4 = 2000-1000 = 1000

In a homicide case 33 different witnesses picked the same man from a line up. the line up contained 5 men. if the identification

polet [3.4K]

the correct question in the attached figure

we know that

the probability
that a witness picks a particular person by chance-----> P=1/5

the probability
that all 7 witnesses would pick the same person-----> P=1/5^7=0.0000128

the answer is the option B 0.0000128

There are a variety of problems in which the number of witnesses change, for example
....find the probability that all 9 witnesses would pick the same person

in this case, the probability would be-------> P=1/5^9=0.000000512

2) 2/7 divided 1/3 = 6/7

3) 4/9 times 3/8 = 1/6

4) 5/8 times 2/15 = 1/12

5) 1 divided 3/4 = 1 1/3

6) 1/8 times 8 =1/64

7) 2 1/4 times 1/6 = 3/8

8) 5/8 times 2 2/3 = 1 2/3

9) 1 1/8 times 4 = 4 1/2

10) 2 1/5 divided 11 = 1/5

11) 4 1/2 times 1 1/3 =6

12) 2 1/7 divided 3 3/7

13) 2 2/9 times 7 = 16
