inn [45]2 years ago
8 0

Answer:

If these are addition:

1) 7

2) 3

3) 1

4) -3

5) 0

6) -5

If they are subtraction:

1) 9

2) 9

3) -7

4) 7

5) -4

6) 3

Step-by-step explanation:

Difference is subtraction, but your examples (7 and -3 = 10) implies that these are addition problems. Next time please set them up in a mathematical form.

This is how the problems would be set up:

Addition:

1) 8+(-1)= 7

2)6+(-3)= 3

3)-3+4= 1

4)2+(-5)= -3

4)-2+(-2)= 0

6)-1+(-4)= -5

Subtraction:

1) 8-(-1)= 9

2)6-(-3)= 9

3)-3-4=- 7

4)2-(-5)= 7

4)-2-(-2)= -4

6)-1-(-4)= 3

MA_775_DIABLO [31]

Answer:

The objective of the problem is obtained below:

From the information, an urn consists of, 4 black, 2 orange balls and 8 white.

The person loses $1 for each white ball selected, no money is lost or gained for any orange balls picked and win $2 for each black ball selected. Let the random variable X denotes the winnings.

No winnings probability= 0.011

Probability of winning $1=0.3516

Probability of winning $2= 0.0879

Probability of winning $4= 0.0659

Choose the inverse of y = x2 - 10x.
PilotLPTM [1.2K]

=Y2-10Y

We move all terms to the left:

-(Y2-10Y)=0

We add all the numbers together, and all the variables

-(+Y^2-10Y)=0

We get rid of parentheses

-Y^2+10Y=0

We add all the numbers together, and all the variables

-1Y^2+10Y=0

a = -1; b = 10; c = 0;

Δ = b2-4ac

Δ = 102-4·(-1)·0

Δ = 100

The delta value is higher than zero, so the equation has two solutions

We use following formulas to calculate our solutions:

Y1=−b−Δ√2aY2=−b+Δ√2a

Δ‾‾√=100‾‾‾‾√=10

Y1=−b−Δ√2a=−(10)−102∗−1=−20−2=+10

Y2=−b+Δ√2a=−(10)+102∗−1=0−2=0

Addison worked 6 more hours this week than last week. In total, she worked 72 hours this week and last week. Using the equation
MArishka [77]

Answer:

h = 33 hours

Step-by-step explanation:

Given that,

Addison worked 6 more hours this week than last week. In total, she worked 72 hours this week and last week.

The equation is :

2h + 6 = 72

We need to find the number of hours

2h = 72 - 6

2h = 66

h = 33

Hence, Adison worked for 33 hours last week.
