Answer:

-9 is your answer for b.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Also note the rule that if you have a positive sign & a negative sign next to each other, the resulting sign would be negative:

b + (-17) = -26

b - 17 = -26

Isolate the variable (b). Add 17 to both sides:

b - 17 (+17) = -26 (+17)

b = -26 + 17

Simplify:

b = -26 + 17

b = -9

-9 is your answer for b.

------------------------------------------------------------------------------------------------------

Remember the rules:

Addition sign + Positive number = Add (Ex: 7 + 7 = 14)

Addition sign + Negative number = Subtract (Ex: 7 + (-7) = 7 - 7 = 0)

Subtraction sign + Positive number = Subtract (Ex: -3 + 4 = 4 - 3 = 1)

Subtraction sign + Subtraction sign = Add (Ex: 5 - (-5) = 5 + 5 = 10)

B=-9 because (-26)-(-17)=-9

You and your friend each collect rocks and fessis your friend collects three times as many roots and half as many fossils as you

n200080 [17]

Answer:

Number of rocks and fossils collected by you is 1 and 24 respectively

Number of rocks and fossils collected by your friend is 3 and 12 respectively

Step-by-step explanation:

Let the number of Rocks you collect be x

Let the number of Fossils you collect be y

Then the total number pf objects you collected will be

x + y = 25

x = 25 - y------------------------------(1)

Your friend collects three times as many rocks and half as many fossils as you.

This can be written as

3x + y (1/2) = 15

3x + (y/2) = 15-------------------(2)

Substituting (1) in (2)

3(25 - y) + (y/2) = 15

75 - 3y + (y/2) = 15

Grouping the like terms we get,

75 - 15 = 3y = (y/2)

60 = ( 6y - y /2)

60 x 2 = 6y -y

120 = 5y

y = 120/5

y = 24

Substituting y value in equation(1) we get

x = 25 - 24

x= 1

y= 24

Friends collects 3 times rock

so collects 3x =3(1) = 3rocks

Also he collects half as many fossils

That is

y/2 = 24/2 = 12 fossils

Hope this help you! :)

Kazeer [188]

Answer:

Step-by-step explanation:

The complete question is given thus:

Suppose that computer literacy among people ages 40 and older is being studied and that the accompanying tables describes the probability distribution for four randomly selected people, where x is the number that are computer literate. Is it unusual to find four computer literates among four randomly selected people?

x P(x)

0 0.16

1 0.25

2 0.36

3 0.15

4 0.08

ANSWER:

The odds that this will occur according to the chart are 0.08, or 8%, so although this is unlikely, it's not terribly unusual.

⇒ NO

So from the following we can say it is not unusual to find four (4) computer literates among four randomly selected people.

ok, so P(1) + P(2) + P(3) + P(4) + P(0) = 0.16+0.25+0.36+0.15+0.08 = 1

Whereas the chance of finding four (4) out of four (4) computer iteration is low when compared to other factors.

cheers i hope this helped !!
