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%

Use foil method (8a - 8)(4a + 1)

Answers

The answer is:  " 32a² − 24a − 8 " .
__________________________________________________
Given:
__________________________________________________
(8a − 8)(4a + 1) ;  Let us expand this expression using the:  "FOIL" method.
___________________________________________________
"FOIL" stands for "First terms, Outer terms,  Inner Terms, Last Terms" ;
           in that order.
___________________________________________________
Basically:
_______________________________________________________
(a + b)(c + d) = ac + ad + bc + bd ;

in which the:

First term is:    "ac" ;
Outer term is:  "ad" ;
I nner term is:   "bc" ;
Last term is:    "bd " .
__________________________________
So; we have (given):

(8a − 8)(4a + 1) ;
__________________________________________________
Let's take the "First, Outer,  Inner, and Last terms" ; as follows:
__________________________________________________
F:  (8a)*(4a) = 32a² ;
__________________________________________________
O:  (8a)*(1) = 8a ;
__________________________________________________
I :   (-8)*(4a) = -32a ;
__________________________________________________
L:  (-8)*(1) = -8
__________________________________________________
Now, let us write out these terms:
__________________________________________________
  32a² + 8a − 32a - 8 ;
__________________________________________________
Now, combine the "like terms" in this expression; to simplify:

       + 8a − 32a = -24a ;
__________________________________________________
and rewrite the simplified expression ; which is:
__________________________________________________
        32a² − 24a − 8 .

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

Hi there!

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 parallel sides are congruent, or equal in length, so

6-2 = x+x
4 = 2x
2x = 4
x = 2

If x = 2, then 
BC = 6-x = 6-2 = 4
AD = x+2 = 2+2 = 4
meaning that the top and bottom parallel sides are each 4 units long

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

Similarly, the opposite angles are congruent as well

Angle A = Angle C
100-y = 12+y
100-12 = y+y
88 = 2y
2y = 88
y = 44

If y = 44, then 
angle A = 100-y = 100-44 = 56
angle C = 12+y = 12+44 = 56

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

Let the side of the square = x

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.

Which of the following numbers is irrational? a fraction with numerator negative 9 and denominator 5, a fraction with numerator square root of 5, a fraction with numerator 7 and denominator 3, square root of 9

Answers

A fraction with numerator -9 and denominator root 5.

With the other scenarios, every number is rational. All whole numbers/integers are rational. The root of 9 is 3, which is whole and rational. Negative numbers are also rational so long as they are whole/an integer. This allows for you to be able to write a fraction using only integers (or with decimals that have a finite end).

However the root of 5 goes on infinitely.

Answer:

The answer is square root of 5.

Step-by-step explanation:

Irrational numbers are those that cannot be expressed as a ratio of two integers.

And when we express these in decimal form, they have an infinite and nonrecurring expansion like the number π and the square root of 2.

The answer is square root of 5. This is because the square root of 5 will never result in a number that will be exact.

b)AB//CD, and AB bisects CD
c)AB//CD, but AB does not bisect CD
d)AB is neither parallel nor perpendicular to CD

Answers

Answer:

The correct answer is option a.

Step-by-step explanation:

If a line passing through two points, then the slope of a line is defined as

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The coordinates of the endpoints of are A(3, 6), B(8, 7), C(3, 3), and D(8, 4).

[tex]m_{AB}=\frac{7-6}{8-3}=\frac{1}{5}[/tex]

[tex]m_{CD}=\frac{4-3}{8-3}=\frac{1}{5}[/tex]

Since slope of AB and CD are same, therefore the line AB is parallel to CD because the slope of parallel lines are equal.

Two parallel lines never intersect each other, therefore AB does not intersect CD. Only option a is correct.

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

ratio of students selected on the team / the number of students trying out...

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.
Calculation for Girls
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

y = 8
x = 5
y = −11

Answers

The equation of a horizontal line passing through the point (−3, 8) is y= 8

How to determine the equation of a horizontal line passing through the point (−3, 8)

From the question, we have the following parameters that can be used in our computation:

The point (−3, 8)

The equation of a horizontal line is of the form

y = c, where

c is a constant.

Since the line is horizontal, the value of y is constant for all points on the line.

In this case, the line passes through the point  (−3,8), so the equation of the horizontal line is  y = 8.

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

The break-even point is the point in which a business makes no gain and no loss.

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.
