What is the probability of rolling a 1 ora 4 on a number cube labeled 1 through 6?
Answer:
For each number, there is a 1/6 probability of rolling it (so 1/6 for the 1 and also 1/6 for the 4).
This means that the probability of rolling either a 1 or a 4 on a given roll is
1 /6 + 1 /6 = 2/6 = 1/3

Shannon is planning a surprise birthday party. She has to rent tables and chairs, and each table costs $35.00 and each chair costs $6.00. The other costs of the party are $315.00. Which of the following expressions represent the total cost of the party?
Answer:
A. 35t + 6c +315
Step-by-step explanation:
The correct expression to represent the total cost of the party is,
⇒ 35t + 6c + 315
Where, 't' is number of table and 'c' is number of chairs.
Option A is correct.
What is an expression?
Expression in math is defined as the collection of the numbers, variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that;
Shannon has to rent tables and chairs for party.
Price of each table = $35.00
Price of each chair = $6.00
The other cost of the party = $315.00
Now,
Let total number of table = t
Then, Total cost of the table= $35t
Let total number of chairs = c
Then, Total cost of chairs = $6c
And, The other cost of the party = $315.00
So, Total cost of the party = 35t + 6c + 315
Thus, The correct expression to represent the total cost of the party is,
⇒ 35t + 6c + 315
Where, 't' is number of table and 'c' is number of chairs.

Step-by-step explanation:
13). (x³ - x² + 4) - (3x³ - 2x² + 3)
= x³ - x² + 4 - 3x³ + 2x² - 3
= x³ - 3x³ - x² + 2x² - 3 + 4
= -2x³ + x² + 1
14). (3x + 4y - 3z) - (2x - 6y + 7z)

Step-by-step explanation:
Got it right on the practice :)
Based on the data presented , the answer is that Yes, it show repeated and periodic behavior. and thus the data indicate that a sine regression is appropriate in this case.
What leads to a new moon phase?This occurs as our Moon is said to orbits around Earth. the side of the moon that is facing the Sun is said to be illuminated due to the sun's brightness, just like when the Earth's daylight side is also said to be illuminated by the Sun.
We tend to have a “new Moon” only when our Moon is said to orbit around the Earth and thus moves it between Earth and the Sun.
See options below
Using the information above, plot the data points. Does this data indicate that a sine regression may be appropriate in this case?
a. Yes, it shows repeated and periodic behavior.
b. Yes, it shows a curve increasing from left to right.

What is the area and perimeter of the following figure
Answer:
AREA: 3000 sq. un. PERIMETER: 232 un.
Step-by-step explanation:
The area of the parallelogram + the two added triangles is 3360. The area of each added triangle is 180. So, 3360 - 2(180) is 3000. That's the area.
To find the perimeter, use the pythagorean theorem. 1600 + 81 = c^2. 41 = c. So after all this, you can finally do 75 + 75 + 41 + 41 = 232

Find the normal approximation to the chance that the face with six spots appears between 9, 10, or 11 times.
The exact chance that the face with six spots appears 9, 10, or 11 times?
my solution; in one roll of the die P(6 spots)=16 In 60 rolls of the die the expected number of times the face with 6 spots appears is given by E(X)=Mean=606=10 times.
SE(6spots)=SD=SQR(606⋅56)=2.8868
Applying the normal approximation to the chance that the face with six spots appears 10 times, I obtain the following: mean = 10
Standard deviation=2.8868
Using the continuity correction of 0.5 the following z-scores are found: z1=(9.5−10)/2.8868=−0.1732 and z2=(10.5−10)/2.8868=0.1732 Subtracting the cumulative probabilities for the two z-scores gives 0.5688−0.4312=0.1376 which is the approximate chance that the face with six spots appears 10 times. find the six spots appears between 9,10, or 11?
The exact chance that the face with six spots appears 10 times is found from
60C10(16)10×(56)50=0.137 find six spots appears 9, 10 or 11 times
Nadia needs 2/5 cup of orange juice for a punch recipe. She will double the recipe to make punch for a party. Which statement is true?
Answer:
Step-by-step explanation:
There's not a lot to go on with the details provided in the question, but based on all you said, if there isn't more to the question, then the true statement is the fact that Nadia needs 2/5 cup of orange juice for punch recipe.
Twice that amount is 4/5, and logically, that can't suffice in a party, except it's a party of 3, maybe 5 people. I'm assuming the people in the party would be much more than that. Makes the fraction impossible

Find the area of the following composite figure: A circle with a area of 50 inches, a rectangle with an area of 75 inches, and a square with an area of 20 inches. ***HINT: since we have the areas, all we have to do is add the areas of each shape to find the composite area.
Answer:
145 inches
Step-by-step explanation:
Area of the circle = 50 inches
Area of the rectangle = 75 inches
Area of the square = 20 inches
Composite area = Area of the circle + Area of the rectangle + Area of the square
= 50 inches + 75 inches + 20 inches
= 145 inches
Composite area = 145 inches

= 1
Answer: x=-1,1
Step-by-step explanation:
16x^2+9=25 first we subtract 9 from the right and left sides.
16x^2=16
Divide both sides by 16 to isolate x
x^2=1
Take the square roots of both sides to isolate x completely.
x=1,-1

I SHALL REWARD THEE WITH BRAINLIEST Change -2Y - 2X = -6 to the slope intercept form of the equation of a line (I NEED EXPLANATIONS FOR FURTHER QUESTIONS I GET STUCK ON) :3 ty and hawwo
Answer:
y = -x + 3
Step-by-step explanation:
First of all, you need to memorize several forms of the equation of a straight line. Here you have -2y - 2x = -6 in "standard form" and want the equivalent equation in "slope intercept form," y = mx + b.
To get this, solve the first equation for y by dividing all three terms by -2:
y + x = 3.
Then solve this result for y:
y = -x + 3
This is the desired equation in slope-intercept form.
The conditional relative frequency table below was generated by column using frequency table data comparing the number of calories in a meal to whether the meal was prepared at home or at a restaurant.
A 4-column table with 3 rows titled number of calories and location of meal preparation. The first column has no label with entries greater than or equal to 500 calories, less than 500 calories, total. The second column is labeled home with entries 0.15, 0.85,1.0. The third column is labeled restaurant with entries 0.55, 0.45, 1.0. The fourth column is labeled total with entries 0.28, 0.72, 1.0.
A nutritionist attempts to determine an association between where food is prepared and the number of calories the food contains. Which is most likely true?
An association cannot be determined because the value 0.55 is similar to the value 0.45.
There is an association because the value 0.15 is not similar to the value 0.55.
There is an association because the sum of each column is 1.0.
An association cannot be determined because the sum of the rows going across is not 1.0.
There is an association because the value 0.15 is not similar to the value 0.55
For the nutritionist to determine whether there is an association between where food is prepared and the number of calories the food contains, there must be an association between two categorical variables.
The conditions that satisfy whether there exists an association between conditional relative frequencies are:
1. When there is a bigger difference in the conditional relative frequencies, the stronger the association between the variables.
2. When the conditional relative frequencies are nearly equal for all categories, there may be no association between the variables.
For the given conditional relative frequency, we can see that there exists a significant difference between the columns of the table in the picture because 0.15 is significantly different from 0.55 and 0.85 is significantly different from 0.45
We can conclude that there is an association because the value 0.15 is not similar to the value 0.55
