Answer: 0.42

Step-by-step explanation:

Max accidently mixed 56 turnip seeds and 78 cabbage seeds together because the two seeds look nearly

identical. The probability of choosing a turnips seed will be:

Turnip seed= 56

Cabbage seeds= 78

Total seeds= 56+78 = 134

Probability of choosing a turnips seed:

= 56/134

= 0.42

At a certain school, intro to economics and intro to calculus meet at the same time, so it is impossible for a student take both

zimovet [89]

Answer:

0.74

Step-by-step explanation:

P(A∪B) = P(A) + P(B) - P(A∩B) = 0.57 + 0.17 - 0

P(A∪B) = 0.74

The probability of A∩B is zero because the classes are mutually exclusive.

artcher [175]

Answer:

y=7+3x

Step-by-step explanation:

Since she already has 7 in her account and she ADDS 3 more each day you would multiply 3 by x which represents the number of days and add that to seven because she already had it. This would equal to Y which represents the total in her account

Ms.Gibson made an initial deposit of $500 when opening a bank account. After the initial deposit, she deposited the same amount

Zigmanuir [339]

Let say the number of the months is t, the total amount of depo is a and a0 is the initial amount of money deposited. You can put it like this:
a= f(t) = a0 + x*t

You can solve the equation by inserting two of any t value. If you use f(8)-f(4) it will be
a0+ x(8)= 2500
a0+ x(4)= 1500
___________-
8x- 4x= 1000
4x= 1000
x=250

Then the new equation would be:
a= a0 + 250*t
Putting f(4) value you can find a0
1500= a0+ 250*4
a0=1500-1000=500

The final equation would be
a= 1000+ 250*t
