Answer: C 30 it was correct on my test
The estimated probability that at least two of the puppies will be female is 60%.
What is probability?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%.

An integer is 15 more than 2 times another. If the product of the two integers is -25, then whats the integers.
Answer:
15 + 2 x X = -25
Step-by-step explanation:
subtract 15 from both sides
2 x X = -40
divide two from both sides
X = -20

I need helppp!! This is confusing !
Answer:
9
Step-by-step explanation:
So the little arrows on the lines means they are equal to each other so if you look, A to D and B to C have only one arrow meaning those two lines are the same lines
and A to B and D to C have two arrows meaning those two lines are the same
so that means if A to B is 9 and it's equal to the line D to C, then D to C is also 9
Hopefully this wasn't too confusing
Answer:
mCD = 9
Step-by-step explanation:
Because this polygon has opposite parallel sides, meaning each side across from each other are parallel, we know that this is a parallelogram. So:
AB ║ DC
BC ║ AD
Because this is a parallelogram, we know that, from the properties parallelograms, opposite sides of a parallelogram are congruent. This means that AB ≅ DC.
This also means that because AB = 9 and AB = DC, DC = 9.
Here's a mini two-column proof:
Statements → Reasons
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
mAB = 9 → Given
AB ║ DC, BC ║ AD → Given
ABCD is a parallelogram → Definition of a Parallelogram
AB ≅ DC → Opposite sides of a parallelogram are congruent.
mAB = mDC → Definition of Congruent Segments
9 = mDC → Substitution Property of Equality
mCD = mDC → Reflexive Property of Equality
mCD = 9 → Substitution Property of Equality

Answer:
part A: D Marina
part B: A Anna
Step-by-step explanation:
If you're not that familiar with these fractions and their equivalents, you can always compare them using their least common denominator: 24.
Joseph: 1/3 = 8/24
Anna: 1/6 = 4/24
Elvin: 3/12 = 6/24
Theo: 1/4 = 6/24
Marina: 5/8 = 15/24
Then the ordering from least-to-greatest is ...
Anna, {Elvin, Theo}, Joseph, Marina
Part A
Marina reached the greatest fraction of the goal.
Part B
Anna reached the least fraction of the goal.

Step-by-step explanation:
A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore. Suppose that a storm is in progress with a severe storm class rating. Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. The next 10 waves have an average wave height is 16 feet with a SD of .6 ft. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis
Answer:
The alternate hypothesis is:
[tex]H_{a} < 16[/tex]
Step-by-step explanation:
There are two types of hypothesis. The null hypothesis and the alternate hypothesis. The null hypothesis is that the mean found is equal to the expected value. The alternate hypothesis is a question about this expected value(different, more, less)
A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore.
This means that the null hypothesis is [tex]H_{0} = 16.4[/tex]
Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis
Dying down means lower average peak, that is, lower than the average of 16.4. This means that the alternate hypothesis is:
[tex]H_{a} < 16[/tex]

Answer: 5/12
Step-by-step explanation:
Answer:
5/12
Step-by-step explanation:
We are going to change both number so they have the same denominators.
1/4x3/3= 3/12
2/3x4/4=8/12
Once we changed the number we are going to subtract the numbers.
8/12-3/12=5/12
We can't simplify 5/12 so the answer is 5/12.

Answer:
f(x) - g(x) = 7x^4+2x^2-3x-10
Step-by-step explanation:
f(x) = 10x^4 + 2x^2 +1
g(x) = 3x^4 +3x +11
f(x) - g(x) = 10x^4 + 2x^2 +1 - ( 3x^4 +3x +11)
Distribute the minus sign
f(x) - g(x) = 10x^4 + 2x^2 +1 - 3x^4 -3x -11
Combine like terms
f(x) - g(x) = 7x^4+2x^2-3x-10

a number increased by 9 is 13
Answer:
4
Step-by-step explanation:
To find the number you have to reverse the equation
Let us call the number "x"
x + 9 = 13
So to find x we flip the equation
13 - 9 = x
Solve it
4 = x
So the missing number is 4
10÷ 5/8 I need help to answer this
Answer:
16
Step-by-step explanation:
10÷5/8=16
Answer:
16
Step-by-step explanation:
To solve problems where a fraction is being divided, we use a reciprocal of the fraction, which means that you flip the fraction upside down and multiply by the other number. So for this problem, the opposite of 5/8 is 8/5, so we need to multiply that by 10.
10*8/5
80/5

solve following values for x and y
Answer:
value of x
(8x+7)°=(9x-4)°
vertically opposite angles are equal
8x°-9x°=-4°-7°
-x°=-11°
divide both sides by -1° don't counsel negative
x=11
value of Y
5y°=(7y-34)°
vertically opposite angles are equal
5y°-7y°=34°
-2y°=34°
divide both sides by-2° don't counsel negative
y=17
