Joan and Ernie are earning money for summer camp. Joan receives a $7 weekly allowance plus $6 for each hour she helps her father

paint. Ernie writes the equation LaTeX: y\:=\:5x\:+7y = 5 x + 7 to represent the relationship between the number of hours he helps his father with yard work and his weekly allowance.
Which person has the greater rate of change?
Which person has the greater y – intercept?
Which has more money at 10 weeks?

Choose all that apply

Joan has more money in 10 weeks

Joan has the greatest rate of change

Joan has the greatest y-intercept

They have the same amount of money in 10 weeks

Their rate of change is the same

Ernie has the greatest rate of change

Ernie has more money in 10 weeks

Ernie has the greatest y-intercept

Their y-intercepts are the same

Calculate the (modeled) probability P(E) using the given information, assuming that all outcomes are equally likely.
Luba_88 [7]

The probability P(E) is 13/15.

According to the statement

we have given that the S = {1, 3, 5, 7, 9}, E = {1, 5, 7}

And we have to find the probability P(E).

So, For this purpose

Recall the formula for the probability of an event E in case when all outcomes are equally likely:

P(E)= n(E) /n(S)

in which S is the sample space.

But we have the S = {1, 3, 5, 7, 9},

so, n(S) = Sum of all outcomes / number of outcomes

n(S) = 1+3+5+7+9 /5

n(S) = 25 /5

n(S) = 5 and

For n(E) = Sum of all outcomes / number of outcomes

n(E) = 1+5+7 /3

n(E) = 13 /3

n(E) = 13 /3

Substitute these values in the above written formula then

P(E)= n(E) /n(S)

P(E)=  (13/3)/ 5

P(E)= 13 /15

So, The probability P(E) is 13/15.

What is the difference between infinite solutions and all real numbers?
igomit [66]

Answer:

Real numbers are like pi, 4, -3, 1/3, 1.25, -3468374, ......

Infinite solutions are like when you solve a problem and it doesn't work out.

like 2+2 = 3 + 2

4 = 5

It doesn't make sense at all

Hope it helps :)

Find the coordinates of the point (x,y,z)(x,y,z) on the plane z=2x+3y+3z=2x+3y+3 which is closest to the origin.
Ainat [17]
The vector equation of the line through the origin perpendicular to the plane is
.. (x, y, z) = t(2, 3, -1)
so the point of interest will satisfy
.. 2(2t) +3(3t) -(-t) = -3
.. 14t = -3
.. t = -3/14
and its coordinates are (x, y, z) = (-3/7, -9/14, 3/14)
