Step-by-step explanation:

The total value of the furniture that was sold by Dennis is 3,500 dollars.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Dennis made an extra $245.00 for selling furniture.

Let the cost of the furniture be x.

Let the total value of the furniture be x + 245.

The extra $245.00 was 7% of the total value of the furniture he sold.

0.07(x + 245) = 245

         x+ 245 = 3500

                   x = 3255

Then the total value of the furniture is (3,255 + 245 =) $3,500.

Step-by-step explanation:

Answer:

feet per minute

300/2 = 6750/45 = 150 ft/minute

Since submarines dive quickly, and need to be able

to respond rapidly to sudden changes in conditions,

it is more reasonable to use feet per minute.  If we work

in feet per hour at this speed we would need to convert

the data back to feet per minute in order to ensure we

don't dive too deep.

Dn = Dn-1 + 150m

where Dn is depth, Dn-1 is previous depth,

and m is number of minutes diving.

The probability that the 2 boys are seated next to each other will be P(A) = 0.16.

Given is that in a movie theater, 2 boys and 3 girls are randomly seated together in a row.

The total number of ways in which all of them can be seated are -

n{S} = (2 + 3) x (2 + 3) = 5 x 5 = 25

n{S} = 25

The total number of ways in which two boys can be seated together are -

n{A} = 4

So, the probability that the 2 boys are seated next to each other will be -

P(A) = n(A)/n(S)

P(A) = 4/25

P(A) = 0.16

Therefore, the probability that the 2 boys are seated next to each other will be P(A) = 0.16.

Answer:

1/4

Step-by-step explanation:

Answer:

1/4

Step-by-step explanation:

To find the slope of a graph, use rise/run or change of y over change of x.

Just from looking at the graph, the slope has to be positive as the line is going up!

Start from the point that intersects with the line and graph. Then find another point that also intersects with the line and graph as well.

So for this graph, I am using the two points to the left.

I start from the bottom point and go up 1. Then I go to the right 4 times until I get to the second point.

Thus, the slope is 1/4!

Hope this helps :D

Answer:

Step-by-step explanation:

(let's assume that people are either classified as man or woman)

m=man

b=buy

a

a.) we are looking for b

we are given

m'=.4

b|m'=.37

b|m=.21

b=b∩m+b∩m'

b∩m= (1-.4)(.21)

b∩m'=.4*.37

b= .274

b.) we are looking for m'|b

m'|b= m'∩b/b

m'∩b=.4*.37

b= .274

m'|b=.540145985

c.)

m|b'= m∩b'/b'

m=m∩b'+m∩b (law of total probability)

.6=m∩b'+.6*.21

m∩b'=.474

.474/(1-.274)= .652892561985

Answer:

The missing length is 37.

Step-by-step explanation:

Perimeter is basically adding up the sides.

So,

8+25+25+15+15=88

125-88= 37

Step-by-step explanation:

the most common form of line equation is

y = ax + b

a is the slope of the line. it is expressed as the ratio

y coordinate change / x coordinate change

when going from one point to the other.

b is the y-intercept (the y value when x = 0).

once we have the slope, we get b by using the coordinates of one of the given points as x and y in the equation and since for b.

for slope a :

x changes by -6 (from 4 to -2)

y changes by +36 (from -31 to 5)

so, the slope is +36/-6 = -6

and the equation looks now like this

y = -6x + b

let's use the second point

5 = -6×-2 + b = 12 + b

-7 = b

the full equation is

y = -6x - 7

Answer:

y=(x-4)^2=x^2-8x+16

So

y=(x-4)^2

Answer:

77%, yes pass, at least 16

Step-by-step explanation:

so 17/22 is 0.77, convert to percentage is 77%

77% is above 70% so you passed

if you guess and check, 15/22 is 68%. since thats just a bit lower than 70%, u need at least 16 questions to pass

yw in advance :))

Answer:

a) 77%   b) Yes   c) 16

Step-by-step explanation:

17 out of 22 questions correct is set up as

17/22= .7727

round this number down and take it from decimal form to percentage.

.77 x 100 = 77%

You scored a 77% and you did score enough to pass.

The minimum number correct to still be able to pass is 16.

16/22 = .7273 = 73%
