Enter the correct answer in the boxes,
Answers
Using it's concept, it is found that there is a 0.04 = 4% experimental probability of rolling a 5 on the red number cube, NCI, and a 2 on the blue number cube, NC2.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In an experimental probability, these number of outcomes is taken from previous trials.
Researching this problem on the internet, it is found that out of the 250 rolls, 10 resulted in a 5 on NC1 and 2 on NC2, hence:
p = 10/250 = 1/25 = 0.04.
0.04 = 4% experimental probability of rolling a 5 on the red number cube, NCI, and a 2 on the blue number cube, NC2.

Triangles J K L and X Y Z are shown. Angles K J L and Y X Z are right angles. The length of Y X is 10. The length of hypotenuse K L is 10.
Could ΔJKL be congruent to ΔXYZ? Explain.
Yes, if JL ≅ XZ.
Yes, if XZ = 10.
No, because the hypotenuse of one triangle is equal in length to the leg of the other triangle.
No, because the leg of one triangle is equal in length to the leg of the other triangle.
Answers
ΔJKL and ΔXYZ CANNOT be congruent triangles because: the hypotenuse of one triangle is equal in length to the leg of the other triangle.
What are Congruent Triangles?Congruent triangles are triangles whose corresponding sides are congruent to each other.
The hypotenuse of triangle JKL(KL = 10) is congruent to a leg of triangle XYZ (YX = 10). This implies that they cannot be congruent triangles.
Therefore, ΔJKL and ΔXYZ CANNOT be congruent triangles because: the hypotenuse of one triangle is equal in length to the leg of the other triangle.

Answers
Answer:
1/6
Step-by-step explanation:
This is conditional probability.
If heads is tossed, then and only then does he have the option to draw either green or red and have the full 'Head, Green/Red' combination.
So, the probability of the first event - getting heads, is 1/2, since either heads or tails can be flipped with 50/50 chance.
The probability of the second event - picking either green or red, is 1/3, since there are 6 colour options - blue, red, yellow, green, orange and purple - of which 2 can be chosen. Thus, 2/6, which simplifies to 1/3
Now since these are both independent events, we must multiply their probabilities.
1/3 * 1/2 = 1/6

Step 2 = 10 dots
Step 3 = 13 dots
For pattern A, we have the following rule

Hope this helps :)
Answer:
5/5
Step-by-step explanation:
if you want to divide 1 whole into a fraction then the top number would have to be the same as the bottom number, for example 5/5. The top number is 5 which is the same as the numerator which will equal to 1 whole.
While 1/5 and 3/5 is less than 1 whole
And 5/1 is more than 1 whole but its way past the numerator

Answer:
x ≈ 44°
Step-by-step explanation:
We will use a trigonometry function to solve for x. We can see that we have values for the adjacent side and hypotenuse. This means we will be using cosine. Cosine is [tex]\frac{adjacent }{hypotenuse}[/tex]
cos(x) = [tex]\frac{adjacent }{hypotenuse}[/tex] [Given]
cos(x) = [tex]\frac{4.9}{6.8}[/tex] [Plug-in the values we have]
x ≈ 43.8969 [Find the inverse cosine function of both sides]
x ≈ 44° [Rounding to nearest degree]
Jess is having a private party at the bowling alley. The party costs $99 plus $3 per person who attends. Which expression can Jess use to figure out the total amount of money she owes at the end of the party?
EXPLAIN YOUR ANSWER
33x
33+x
99+3x
99x+3
Answers
Answer:
Total cost= 99 + 2.97x
Step-by-step explanation:
Giving the following information:
Fixed cost= $99
Variable cost= 3% per person
First, we need to calculate the 3% of 99:
Unitary variable cost= 99*0.03= $2.97
Now, we establish the total cost structure:
Total cost= 99 + 2.97x
x= number of people in attendance
Finally, suppose 200 people attend the party:
Total cost= 99 + 2.97*200
Total cost= $693
Answer:
99+3x
Step-by-step explanation:
Given;
Party cost $99
$3 per person who attends
To Find;
Which expression can Jess use to figure out the total amount of money she owes at the end of the party?
Solve;
Since, we don't know the total amount of money she owes at the end of the party. Total amount of money she owes at the end of the party = x
Thus, Party Costs ($99) plus per person who attends($3) and Total amount of money she owes at end of party (x)
As well as,
[A] 33x, [B] 33 + x, and [D] 99x+3 didn't clearly or completely shows the party's situation. Hence, the Best Answer is [C] 99+3x
