A professional baseball team will play 1 game Saturday and 1 game Sunday. A sportswriter estimates the team has a 60% chance of winning on Saturday but only a 35% chance of winning on Sunday. Using the sportswriter's estimates, what is the probability that the team will lose both games?
A) 14%
B) 21%
C) 25%
D) 26%
E) 39%
Answers
Final answer:
To find the probability of losing both games, multiply the probabilities of losing each game together. The probability is 26%.
Explanation:
To find the probability that the team will lose both games, we can multiply the probabilities of losing each game together.
The probability of losing on Saturday is 1 - 60%, or 40%. The probability of losing on Sunday is 1 - 35%, or 65%. Multiplying these probabilities gives us 40% × 65% = 26%.
Therefore, the correct answer is (D) 26%
Of the 30 girls who tried out for lacrosse team at euclid middle school ,12 were selected .of the 40 boys who tried out 16 were selected .and the ratio of the number of studets on the team to the number of students trying out the same for both boys and girls ? how do you know
Answers
boys :
on the team -- 16
trying out -- 40
ratio is : 16/40 which reduces to 2/5
girls :
on the team -- 12
trying out -- 30
ratio is : 12/30 which reduces to 2/5
so yes, the ratios are the same because in both boys and girls, the number of players selected was 2/5 of the total who tried out.
30 ÷6= 5
12 ÷6 =2
∴For Girls 2:5
Calculation for Boys
40 ÷ 4 = 10
16 ÷ 4 = 4
∴ For Boys 4:10---- which = 2:5
If u divided both 4 and 10 by 2
∴Both have the same ratio of 2:5

A dependent variable is a. directly changed by the experimenter. b. manipulated by changes to the independent variable. c. a variable that is kept constant. d. a variable that is used as a control.
Answers
A dependent variable is one that is changed, when the independent variable changes.
For example, if we wanted to calculate how many dollars we've earned in a given amount of time, time would be the independant variable, because it is a constant and is not affected by how much many we earn. The amount of money we earned is directly affected by the independent variable, time.
Your answer is b.
Hope I helped!
Be sure to leave a "Brainliest" if I was helpful. Or not lol. I really don't care tbh XD
Answer:- Option b. is the right answer. A dependent variable is manipulated by changes to the independent variable.
Explanation:-
In mathematical modelling or scientific research a variable is defined as a term that has a quantity that varies. There are two kinds of variables:- 1) dependent variables 2) independent variables.
A independent variable can be change by the experimenter to check the effects on dependent variables which is observed by the him in a scientific experiment.
Thus, A dependent variable is manipulated by changes to the independent variable.
the table shows the annual profits (in thousands of dollars) of a county fair from 2008 to 2012. What must the 2012 profit be (in hundreds of dollars) to break even over the five-year period?
Answers
Let the 2012 profit be x, then
2.5 + 1.75 + (-3.3) + (-1.4) + x = 0
4.25 - 3.3 - 1.4 + x = 0
-0.45 + x = 0
x = 0.45
Therefore, the 2012 profit must be 0.45 thousand dollars = 4.5 hundred dollars to break even over the five-year period.
The 2012 profit must be 0.45 thousand dollars is equal to 4.5 hundred dollars to break even over the five-year period.

Nonstandard dice can produce interesting distributions of outcomes. you have two balanced, six-sided dice. one is a standard die, with faces having 1, 2, 3, 4, 5, and 6 spots. the other die has three faces with 0 spots and three faces with 6 spots. what are the possible values for the total number of spots y on the up-faces when you roll these two dice?
Answers
One die can show the values 1-6, while the other die can only show 0 or 6. So the possible totals are 1 through 6 plus 0 and 1 through 6 plus 6. Written out, one-by-one, this gives: 1+0 = 1 2+0 = 2 3+0 = 3 4+0 = 4 5+0 = 5 6+0 = 6 1+6 = 7 2+6 = 8 3+6 = 9 4+6 = 10 5+6 = 11 6+6 = 12
When rolling a standard die and another die with faces having either 0 or 6 spots, the possible total values y range from 1 to 12, excluding the numbers 5 and 6 twice due to the unique nature of the second die.
Explanation:The question asks about the possible values for the total number of spots y on the up-faces when you roll two nonstandard dice: a standard six-sided die with faces having 1, 2, 3, 4, 5, and 6 spots, and another die with three faces having 0 spots and three faces having 6 spots. To find y, we need to consider all the possible outcomes of rolling these two dice and summing the numbers of spots on the up-faces.
If the standard die shows a 1, y can be 1+0=1 or 1+6=7.If it shows a 2, y can be 2+0=2 or 2+6=8.If it shows a 3, y can be 3+0=3 or 3+6=9.If it shows a 4, y can be 4+0=4 or 4+6=10.If it shows a 5, y can be 5+0=5 or 5+6=11.If it shows a 6, y can be 6+0=6 or 6+6=12.Therefore, the possible values for y are 1, 2, 3, 4, 5, 5, 7, 8, 9, 10, 11, and 12.
The area of a square is 18 sq in less than twice the area of a triangle. the base of the triangle is 3 in longer and the altitude is the same length as the side of the square
Answers
So, the altitude of the triangle = x
and it's base = x+3
2 (area of triangle) - 18 = area of the square
area of the triangle = (1/2)height× base
and
area of the square = side^2
{ (2)(1/2)(x)(x+3)} -18 = x^2
x^2 + 3 x -18 = x^2
3x -18 =0
3x = 18
x = 6
so, the length of one side of the square = 6 units = altitude of the triangle
and the base of the triangle = 6+ 3 = 9cm.

Did I do number 2 right?
Answers
y = a*(x-p)*(x-q)
2 = a*(x-0)*(x-1)
2 = a*(2-0)*(2-1)
2 = a*(2)*(1)
2 = 2a
2a = 2
2a/2 = 2/2
a = 1
So the equation
y = a(x-0)(x-1)
updates to
y = 1(x-0)(x-1)
and that simplifies to
y = x(x-1)
The next step is to distribute the x through to get this final answer
y = x^2-x
