Answer:
#1At the start the total number is 10, male fish = 6
P(m) = 6/10 = 3/5At the second time the total number is 9, male fish = 5
P(m) = 5/9Probability of two male fish is:
P(m and m) = 3/5*5/9 = 1/3#2a) The events are independentb) P(4 and A) = 1/6*1/4 = 1/24c) P(an even number and C) = 1/3*1/4 = 1/12d) P(2 or 5 and B or D) = (1/6 + 1/6)*(1/4 + 1/4) = 1/3*1/2 = 1/6#3P(both goals) = 0.8*0.8 = 0.64

Give the coordinates of point A.
Answer: -2,-5
Step-by-step explanation:
The red point is located in the 3rd quadrant in the graph. So that means both the y and the x are negative. So first you go by the x value, the point is located on the 2 space left (-) from the origin (center) of the graph and then you have to go 5 spaced down (-). So point A is located at (-2,-5).

A- Jon paid $235.50 for yard work. He paid $25.00 to have some
bushes trimmed and $35.50 each time he had his grass mowed. What is
x, the number of times Jon had his yard mowed? | The equation is 25x + 35.50 = 235.50 . That means this answer is probably wrong.
·
C- Jon paid $235.50 for yard work. He paid $35.50 to have some
bushes trimmed and $25.00 each time he had his grass mowed. What is
x, the number of bushes Jon had trimmed? | Once again, the equation is 25x + 35.50 = 235.50 . That means this answer is probably wrong too.
·
D- Jon and his neighbor paid $235.50 for yard work. Jon paid $35.50 to have some bushes trimmed and his neighbor had some bushes trimmed for $25.00 each. What is x, the amount of money Jon paid to have his bushes trimmed? | It says that Jon paid $35 to have his bushes trimmed in the sentence.
~~~~~~~~~~~~~~~~~~~~
B- Jon paid $235.50 for yard work. He paid $35.50 to have some
bushes trimmed and $25.00 each time he had his grass mowed. What is
x, the number of times Jon had his yard mowed?
The equation is 25x + 35.50 = 235.50 || We would put the x after 25 because it's asking "What is x, the number of times Jon had his yard mowed?" This seems correct.
Therefore, the answer would be B

a cashier at the supermarket has $685 in 4 different denomination bills in her register at the end of the day. the number of $5 bills was 10 more than 4 times the amount of $10 bills. the register contained as many $1 bills as $5 bills and $10 bills combined, and two $50 bills. how many bills of each kind did the register contain?
9514 1404 393
Answer:
85 ones70 fives15 tens2 fiftiesStep-by-step explanation:
Let a, b, c, d represent the numbers of $1, $5, $10, and $50 bills, respectively. The problem statement tells us ...
a +5b +10c +50d = 685 . . . . . total amount of cash
b = 10 +4c . . . . . . . . . . . . the number of fives is 10 more than 4 times tens
a = b+c . . . . . . . . . . . as many ones as fives and tens combined
d = 2 . . . . . . . . . . the register contained 2 fifty-dollar bills
__
Substituting for 'a', then for 'b', we have ...
(b+c) +5b +10c +50d = 685
6(10 +4c) +11c +50d = 685
60 +35c +50d = 685
Substituting d=2 and subtracting 160 gives ...
35c = 525
c = 15
b = 10 +4c = 10 +4(15) = 70
a = b+c = 70 +15 = 85
The register contained ...

Answer:
for what
Step-by-step explanation:
Line A passes through the points (-3,2) and (-23,54). Line B is parallel to line A and passes through the point (-8,0). Consider
the equation of line B in the form y= a (x + b), where a and b are rational numbers.
Answer:
Line A passes through (-3, 2) and (-23, 54)
slope of line A will be
[tex]m_{A} =\frac{y_{2}-yx_{1} }{x_{2}- x_{1} } = \frac{54-2}{-23+3} = \frac{52}{20}= \frac{13}{5}[/tex]
Equation of line A will be
[tex](y - y_{1}) = m_{A}(x-x_{1} )\\\\(y - 2) = \frac{13}{5}(x -(-3))\\\\(y - 2) = \frac{13}{5}(x +3))\\ \\\\5((y - 2) = 13(x +3))\\\\5y -10 = 13x + 39\\\\5y = 13x + 49[/tex]
Given line B is parallel to line A, So slope of A and B
[tex]m_{A} \cdot m_{B} = 1[/tex]
slope of line B will be
[tex]\frac{13}{5}\cdot m_{B} = 1\\\\m_{B} = \frac{5}{13}[/tex]
Also given line B passes (-8, 0), therefore the equation of line B
[tex](y-y_{B}) = m_{B}(x-x_{B} )\\\\(y - 0) = \frac{5}{13}(x + 8)\\\\y = \frac{5}{13}(x+8)\\\\[/tex]
Therefore,
[tex]a = \frac{5}{13} \ \ and \ b = 8[/tex]
