Answer:
(C) The ratio of boys who preferred C is equal to the ratio of girls who preferred C
Step-by-step explanation:
A is incorrect because the ratio of girls to boys in the survey is 120/80 which is 60%
B is incorrect because the ratio of girls who prefrerred B to the ratio of boys is 10/25 not 10/35
D is incorrect because once again 20/15 does not equal 20/35
C is the correct answer and the only correct answer despite the multiple choice question because the ratio of boys that preferred c to girls is the exact same

You bike 4 miles the first day of your training, 4.2 miles the second day, 4.6 miles the third day, and 5.4 miles the fourth day. If you continue this pattern, how many miles do you bike the seventh day?
On the seventh day, following the pattern of doubling the increment from the previous day, the biker would bike 16.6 miles.
To determine how many miles will be biked on the seventh day, we need to recognize the pattern in the distances biked each day. Starting with the first day and continuing through the fourth day, we see increases of 0.2 miles, 0.4 miles, and 0.8 miles respectively. It seems that each day, the increment from the previous day doubles.
Day 1: 4 milesDay 2: 4 + 0.2 = 4.2 milesDay 3: 4.2 + 0.4 = 4.6 milesDay 4: 4.6 + 0.8 = 5.4 milesFollowing this pattern, the distances for the next three days would be:
Day 5: 5.4 + 1.6 (double of 0.8) = 7 milesDay 6: 7 + 3.2 (double of 1.6) = 10.2 milesDay 7: 10.2 + 6.4 (double of 3.2) = 16.6 milesTherefore, the biker would bike 16.6 miles on the seventh day of training following this pattern.

Divide by -2
-4= x
Final answer:
To find x when y = 5 in the equation y = -2x - 3, the solution is x = -4.
Explanation:
In the given equation y = -2x - 3, to find x when y = 5, substitute y with 5 in the equation:
5 = -2x - 3
Solve for x:
Add 3 to both sides: 5 + 3 = -2x

A) 7x x 5=$50.00
B)7x =$75.00
C)7x+ $15.00=$65.00
D)5x=$65.00-$15.00
Plse make sure ur answer has an explanation
THANK U AND ENJOY UR 25 POINTS!!
Answer:
A.) 7x x 5=$50.00
Step-by-step explanation:
You can eliminate B and C as they don't include the 5 different stores.
D is incorrect because it doesn't include the 7 items.
Therefore, A is correct because 7x is the 7 items multiplied by the average cost per item and you multiply by 5 because she does that at each of the 5 stores. It = to 50 because she started with $65 but ends up with $15 so you subtract $65 with $15 to get $50 as that's how much she spent.
Answer:
A
Why:
$65.00-$15.00=$50.00
She visited 5 stores, and she bought 7 items.
So therefore it would be A.

Find the volume of a pyramid with a square base, where the side length of the base is 8.7 cm and the height of the pyramid is 13.1 cm
Answer:
V = 330.513 cm^3
Step-by-step explanation:
Area = l x w and with a square the length and width are the same, additionally the volume of a pyramid can be found by using the formula (L)(w)(h)/3 so
8.7 x 8.7 = 75.69cm^2
75.69 x 13.1 = 991.539
991.539 ÷ 3 = 330.513 cm^3
Mark as brainliest please :)
Final answer:
The volume of a pyramid with a square base of side 8.7 cm and height 13.1 cm is calculated using the formula for volume, resulting in 330.35 cm³.
Explanation:
To find the volume of a pyramid with a square base, you can use the formula V = (1/3) × base area × height, where the base area for a square is given by side length × side length.
In this case, the side length of the base is 8.7 cm, and the height of the pyramid is 13.1 cm.
First, calculate the area of the base:
Base Area = 8.7 cm × 8.7 cm = 75.69 cm²
Then, calculate the volume of the pyramid:
Volume = (1/3) × 75.69 cm² × 13.1 cm = 330.35 cm³
Therefore, the volume of the pyramid is 330.35 cm³.

Mrs. Culland is finding the center of a circle whose equation is x2 + y2 + 6x + 4y – 3 = 0 by completing the square. Her work is shown. x2 + y2 + 6x + 4y – 3 = 0 x2 + 6x + y2 + 4y – 3 = 0 (x2 + 6x) + (y2 + 4y) = 3 (x2 + 6x + 9) + (y2 + 4y + 4) = 3 + 9 + 4 Which completes the work correctly?
We have been given that Mrs. Culland is finding the center of a circle whose equation is [tex]x^2+y^2+6x+4y-3 = 0[/tex] by completing the square. We are asked to find the final step of her work.
Let us complete the square.
We know that to complete square, we need to add the half the square of coefficient of x and y term.
[tex]x^2+y^2+6x+4y-3+3 = 0+3[/tex]
[tex]x^2+6x+y^2+4y=3[/tex]
We can see that coefficient of x is 6 and coefficient of y is 4.
[tex](\frac{6}{2})^2=3^2=9[/tex]
[tex](\frac{4}{2})^2=2^2=4[/tex]
Now we will add 9 and 4 on both sides as:
[tex]x^2+6x+9+y^2+4y+4=3+9+4[/tex]
[tex](x^2+6x+9)+(y^2+4y+4)=16[/tex]
Now we will complete the square as:
[tex](x+3)^2+(y+2)^2=4^2[/tex]
We know that standard form of equation of a circle is in form [tex](x-h)^2+(y-k)^2=r^2[/tex], where point (h,k) represents center of circle and r represents radius of circle.
We can rewrite our equation as:
[tex](x-(-3))^2+(y-(-2))^2=4^2[/tex]
Now we can see that center is at point [tex](-3,-2)[/tex].
Therefore, the equation of the circle would be [tex](x+3)^2+(y+2)^2=4^2[/tex] with a center at point [tex](-3,-2)[/tex].

A survey of 20 Middleton residents was done to determine the number of people in each household. The numerical frequencies are shown in the dot plot.
The outliers are 1, 6 and 9 while the mean is 3.5 and the range is 8
How to Interpret a Dot Plot?
1) From the given dot plot, we can say that the outliers are 1, 6 and 9. This is because these numbers are far away from the general number of people in each household.
2) The mean is;
[(1 * 1) + (2 * 4) + (5 * 3) + (4 * 4) + (5 * 4) + (1 * 9)]/20 = 3.5
3) The range is the difference between the highest number and the lowest number. Thus;
Range = 9 - 1

12 cookies are in a bag. 6 children will share a bag of cookies. The children want to know how many cookies they will each get. Which number sentence would they use to answer the question?
Answer:
12 / 6 = 2
Step-by-step explanation:
If there are a total of 12 cookies, and these cookies will be divided evenly among 12 children, to find how many cookies each children will have, we just need to divide the total number of cookies by the total number of children:
Number of cookies per children = number of cookies / number of children
Number of cookies per children = 12 / 6 = 2
So each children will get 2 cookies.

a 15 inch long windshield wiper blade swipes in arc of 120°. How many square inches of a windshield’s surface area does the blade cover in one swipe
The blade covers an area of 235.714 square inches in one swipe.
In this question, we are to calculate the area that is covered by blade cover of the windshield wiper blade in 1 swipe.
To calculate this, we shall be using the formula for the area of the sector. The sector in this case subtends an angle of 120 degrees at the centre.
Mathematically, the area covered by the blade in one swipe is
A = θ/360 * pi * r^2
where θ = 120 degrees and r = 15 inch
A = 120/360 * 22/7 * 15^2
= 1/3 * 22/7 * 225 = 22 * 75/7 = 235.714 square inches

A number cube labeled one though six is rolled and a letter is selected from
the word MUSIC. Find each probability. P(6 and consonant)
Answer:
1/10
Step-by-step explanation:
In the question above we are given two data sets
a) A number cube labelled and it rolled, 1 to 6
b) A word called Music
We are asked to find the probability of
obtaining a 6 from the rolled dice and picking a consonant.
Step 1
Probability = Number of Possible Outcomes/ Number of events
Probability of obtaining a 6 from the rolled cube = P(6) = 1/6
Step 2
Probability = Number of Possible Outcomes/ Number of events
In the Letter MUSIC, we have 5 letters,
2 Vowels and 3 consonants
The Probability of Obtaining an Consonant = Number of possible outcomes ( Number of consonants) ÷ Number of events ( Number of letters in MUSIC)
P ( Consonant) = 3/5
Step 3
This is the final step
And we are to find the Probability of P(6 and consonant)
P( 6 and Consonant ) = P (6) × P ( Consonant)
P ( 6 and Consonant) = 1/6 × 3/5
= 3/30 = 1/10
Therefore, the Probability of obtaining P(6 and consonant) = 1/10.
Final answer:
The probability of rolling a 6 on a six-sided die and selecting a consonant from the word MUSIC is 1/10.
Explanation:
The probability of rolling a 6 on a number cube and selecting a consonant from the word MUSIC is found by multiplying the probabilities of the two independent events. The probability of rolling a 6 on a six-sided die is 1/6. The word MUSIC has three consonants: M, S, and C. The probability of choosing a consonant from MUSIC is 3/5, since there are 5 letters in total and 3 of them are consonants.
Therefore, the probability of both events occurring is:
P(6 and consonant) = P(6) × P(consonant) = (1/6) × (3/5) = 1/10.

How do you solve 6x^2 +12x-48=0 by completing the square?
Answer:
x = -4 and x = 2
Through the Completing the Square process below:
Step-by-step explanation:
solve 6x^2 +12x-48=0
first divide out the 6
x^2 + 2x - 8 = 0
Then use the Diamond method:
-8 = -2*4 , and -2 + 4 = 2
so
x^2 - 2x + 4x - 8 = 0
x(x - 2) + 4*(x -2) = 0
(x + 4)(x - 2) = 0
so, solve x + 4 = 0 and (x - 2) = 0
x = -4 and x = 2

There are 30 students on the school's student council. A special homecoming dance committee is to be formed by randomly selecting 6 students from student council. How many possible committees can be formed?
To determine the number of ways to form a committee of 6 students from 30 council members, we use the combination formula C(30, 6), which yields 593,775 different combinations.
Explanation:The question asks how many possible committees of 6 students can be formed from a group of 30 students on the student council. This is a combinatorial problem and can be solved using the combination formula which is given by C(n, k) = n! / (k! * (n - k)!), where C(n, k) is the number of combinations, n is the total number of items, and k is the number of items to choose. So to answer the question, we must calculate C(30, 6).
Calculating C(30, 6), we have:
C(30, 6) = 30! / (6! * (30 - 6)!)
C(30, 6) = 30! / (6! * 24!)
C(30, 6) = (30 × 29 × 28 × 27 × 26 × 25) / (6 × 5 × 4 × 3 × 2 × 1)
C(30, 6) = 593,775
There are 593,775 different ways to form a committee of 6 students from a student council of 30 members.
