The estimated probability that at least two of the puppies will be female is 60%.

Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.

For the given situation,

Let heads (H) be the female puppy

Let tails (T) be the male puppy.

The simulation results are the sample spaces.

[tex](THTT, TTTH, TTHH, HTTT, TTTT, HHHH, HTHT, HHHT, THTH, THTH)[/tex]

⇒ [tex]n(s)=10[/tex]

The event is the probability that at least two of the puppies will be

female.

[tex]e=(TTHH, HHHH, HTHT, HHHT, THTH, THTH )\\[/tex]

⇒ [tex]n(e)=6[/tex]

The estimated probability that at least two of the puppies will be

female, [tex]P(e)=\frac{n(e)}{n(s)}[/tex]

⇒ [tex]P(e)=\frac{6}{10}[/tex]

⇒ [tex]P(e)=0.6[/tex]

Thus the percentage of the female puppies = [tex](0.6)(100)[/tex]

⇒ [tex]60\%[/tex]

Hence we can conclude that the estimated probability that at least two of the puppies will be female is 60%.

Answer:

1. 3x-7y and -7y+3x

Step-by-step explanation:

1. 3x -7y and -7y +3x

This is correct because the terms remain unchanged. The -7y stays a -7y and the positive 3x stays a positive 3x.

2. 3x -7y and 7y -3x

This is not correct because the signs of the 3x and 7y switch. For the expressions to be equivalent, the signs must remain unchanged.

3. 3x -7y and 3y -7x

This is not correct because the variables of the 3 and 7 switched. The variables need to stay the same, for the expressions to be equivalent.

4. 3x-7 and -3y+7x

This is not correct because both the variables and the signs of the expressions changed. Both the signs and variables would need to stay the same in order to be equivalent.

Answer:

B) 60.21 ft²

Step-by-step explanation:

Area of a triangle = 1/2bh

You can‘t used mixed measurements (feet and inches), so you have to convert each length to inches

8’6”=102’

14’2”=170’

Now find the area

1/2 x 102 x 170 = 8670 in²

This is one of the answers, but the quetion asks how many quart feet you need.

So, convert it back to feet.

8670 x 0.06944444444 = 60.2083333

(You could also have converted the two lengths to feet. 8’6” = 8.5 ft.  14’2” = 14.16666666.  This way would probably have been faster.

1/2 x 8.5 x 14.166666 = 60.20833333)

Answer:

The Answer Is 6

Step-by-step explanation:

The number of students 6th graders who will need to join the club will be 18.

The utilization of two or more additional numbers that compares is known as the ratio.

The chart below displays the number of students in each grade that are members of Lone Star Middle School's spirit club.

If ten additional eighth-grade students join the group. If the ratio of eighth students to sixth graders remains constant.

Let 'x' be the number of students who join the club in 6th grade. Then the equation is given as,

x / (2 × 10 + 10) = 6 / 10

Simplify the equation, then we have

x / (2 × 10 + 10) = 6 / 10

x / 30 = 3 / 5

x = 30 (3/5)

x = 18

The number of students 6th graders who will need to join the club will be 18.

Answer: y=-4x+6

Step-by-step explanation:

M is the slope in slope intercept form.

y=mx+b

And b is the Y intercept because when you plug in zero for x you get y=b.

So we know

y=-4x+b

Because m is the slope

And y is 6 because it is shown in the parentheses

So we know the answer is y=-4x+6

Step-by-step explanation:

Howdy, did you do a, b, and c by yourself? Because there are some slight issues, so I'll do my best to explain.

a. 3x+5x

We know that x=2, so we can substitute 2 in for x right now, or we can combine like terms.

3x and 5x both have the variable x so we can add them easily to get 8x. If you substitute in 2, you're just multiplying 8×2, which is 16.

b. 5z+4z+z

Again, since

we know that z=-3, we can substitute in now, or we can combine like terms first. 5z, 4z, and z all have the variable x, we addition is easy. 5+4+1=10, so you'll have 10z. Substitute in -3 for z, and you're just multiplying 10×-3=-30

c. 3x+6+5x

This is trickier since 6 doesn't have the variable x. So to combine like terms means to only add 3x and 5x. So the equation will turn out looming like 8x+6. now substitute in 2 for x and you get

8(2)+6

16+6

22

d. 8y+8-4y

Combine like terms

4y+8

substitute in 5 for y

4(5)+8

20+8

e. 5z-4z+z

combine like terms

z+z

2z

substitute -3 for z

2(-3)

f. 3x+6+5x-2

(so that's 3x+5x and 6-2)

8x+4

substitute in 2 for x

8(2)+4

16+4

Answer:

Part A)

Ashley will be on the sixth page.

Part B)

[tex]\displaystyle p=\frac{1}{3}m+5[/tex]

Part C)

Six minutes.

Step-by-step explanation:

Ashley is on the first page and she can read one page per minute.

Emma is on the fifth page and she can read one page every three minutes.

Part A)

We can write an equation for Ashley. Let m represent the amount of minutes that has passed.

Since she is already one the first page, our initial value is 1.

She reads one page every minute. So, after m minutes, she would have read m pages.

Therefore, our equation is:

[tex]p=m+1[/tex]

Where p is the total pages read after m minutes.

Then after five minutes, Ashley will be on the:

[tex]p=(5)+1=6[/tex]

Ashley will be on the sixth page after five minutes.

Part B)

Since Emma reads one page every three minutes, we can say that she reads 1/3 of a page every minute.

Since she started on page five, her equation is:

[tex]\displaystyle p=\frac{1}{3}m+5[/tex]

Part C)

So, both of their pages read must be equivalent. Therefore:

[tex]\displaystyle m+1=\frac{1}{3}m+5[/tex]

Solve for m. Subtract 1/3m from both sides:

[tex]\displaystyle \frac{2}{3}m+1=5[/tex]

Subtract 1 from both sides:

[tex]\displaystyle \frac{2}{3}m=4[/tex]

Finally, multiply both sides by 3/2:

[tex]\displaystyle m=4\Big(\frac{3}{2}\Big)=6[/tex]

So, it will take six minutes before Ashley and Emma have read the same number of pages.
