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%

If f(x)=7x-3 and g(x)=x²,
(g•f)(1)= g(f(1))
bit : f(1) =7(1)-3 = 4
(g•f)(1)= g(f(1)) = g(4) = 1² = 16

If f(x) = 3x + 2 and g(x) = x2 + 1, which expression is equivalent to (f*g) (x)?

Answers

(f*g) (x) = (3x + 2) (x^2 + 1)
(f*g) (x) = 3x^3 + 3x + 2x^2 + 2
(f*g) (x) = 3x^3 + 2x^2 + 3x + 2

Answer: The required expression is [tex]3x^3+2x^2+3x+2.[/tex]

Step-by-step explanation: We are given the following two functions :

[tex]f(x)=3x+2\\\\g(x)=x^2+1.[/tex]

We are to find the expression equivalent to [tex](f*g)(x).[/tex]

We know that

for any two functions p(x) and q(x), we have

[tex](p*q)(x)=p(x)\times q(x).[/tex]

Therefore, we get

[tex](f*g)(x)\\\\=f(x)\times g(x)\\\\=(3x+2)(x^2+1)\\\\=x^2(3x+2)+1(3x+2)\\\\=3x^3+2x^2+3x+2.[/tex]

Thus, the required expression is [tex]3x^3+2x^2+3x+2.[/tex]

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.

What is the equation of a horizontal line passing through the point (−3, 8)?
x = −3
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.

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

Did I do number 2 right?

Answers

You should have
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

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 ;

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

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

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12

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

Final answer:

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.

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.

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.
