Out of the 2500 seventh graders surveyed, 1000 of them do not eat breakfast, based on the proportion of 2 out of 5.
To find out how many seventh graders surveyed do not eat breakfast, we can use the proportion of students who do not eat breakfast from the survey results.
Given:
- Total number of seventh graders surveyed: 2500
- Proportion of seventh graders who do not eat breakfast: [tex]\( \frac{2}{5} \)[/tex]
To find the number of seventh graders who do not eat breakfast, we multiply the total number of seventh graders surveyed by the proportion who do not eat breakfast:
[tex]\[ \text{Number of students not eating breakfast} = \frac{2}{5} \times 2500 \]\[ \text{Number of students not eating breakfast} = \frac{2 \times 2500}{5} \]\[ \text{Number of students not eating breakfast} = \frac{5000}{5} \]\[ \text{Number of students not eating breakfast} = 1000 \][/tex]
Therefore, out of the 2500 seventh graders surveyed, 1000 of them do not eat breakfast.
Which formula can be used to describe the sequence? , −4, −24, −144,...
Answer:
[tex]An= -4(6)^{n-1}[/tex]
Step-by-step explanation:
−4, −24, −144,...
There is no common difference
-24/-4= 6
-144/ -24= 6
common ratio = 6
when there is a common ratio then it is an Geometric sequence
[tex]An= a1(r)^{n-1}[/tex]
a1 is the first term = -4
r is the common ratio = 6
Formula becomes
[tex]An= -4(6)^{n-1}[/tex]

Using the two functions listed below, insert numbers in place of the letters a, b, c, and d so that f(x) and g(x) are inverses.
f(x)= x+a
------
b
g(x)=cx−d
Answer:
[tex]a = 2; \ d = 2; \ c=1; \ b=1[/tex]
Step-by-step explanation:
Two functions are inverse where their composition results in a variable only:
[tex]f(g(x))=x[/tex]
So, we have to insert the right numbers in place of letters a, b, c and d, to fulfil this definition. Those value would be: [tex]a = 2; \ d = 2; \ c=1; \ b=1[/tex]
Replacing these values, we have:
[tex]f(x)=x+2[/tex]
[tex]g(x)=1x-2=x-2[/tex]
Applying the composition [tex]f(g(x))[/tex]:
[tex]f(g(x))=\frac{cx-d+a}{b}[/tex]
We observe that with this values, these functions are inverse, because it composition results x.
[tex]f(g(x))=\frac{1x-2+2}{1}=x[/tex]
Therefore, the values are [tex]a = 2; \ d = 2; \ c=1; \ b=1[/tex]

Five hundred fifty students attended the assembly. If the ratio of boys to girls in the assembly was 5 to 6, how many girls attended the assembly
Final answer:
To find the number of girls attending an assembly given a boys-to-girls ratio, divide the total students by the total parts of the ratio and then multiply by the girls' part of the ratio. 300 girls attended the assembly.
Explanation:
Ratios provide us with comparative information. In this case, the ratio of boys to girls is 5 to 6. To find the number of girls, we need to divide the total students by the total parts of the ratio (5 + 6) and then multiply by the girls' part of the ratio:
Calculate total parts of the ratio: 5 (boys) + 6 (girls) = 11.
Divide total students by total parts of the ratio: 550 / 11 = 50.
Multiply by the girls' part of the ratio: 50 (students per part) * 6 (girls) = 300 girls attended the assembly.

Bryce has two small buckets each containing numbered tiles. The tiles in bucket A are the odd numbers from 1 to 31, one tile per number. The tiles in bucket B are the even numbers from 2 to 32, one tile per number. Bryce draws one tile from bucket A. On the number line below "Bucket A," select the point that represents the probability of drawing a tile that is a prime number from bucket A. He then draws one tile from bucket B. On the number line below "Bucket B," select the point that represents the probability of drawing a tile that is evenly divisible by 6 from bucket B.
total number of prime numbers in bucket A = 10( 3 5 7 11 13 17 19 23 29 31)
Probability = favorable outcomes/ total outcomes = 10/31
total number of numbers evenly divisible by 6 in bucket B = 5(6 12 18 24 30)
probability = 5/31

If the height is 4.41 inches and the volume is 0.734, what will the side length of the pyramid’s base be? Is the number rational or irrational? Why?
The side length of the pyramid's base is approximately 0.7071 inches, and it is an irrational number.
To find the side length of the pyramid's base, we need to use the formula for the volume of a pyramid, which is given by:
[tex]\[ V = \frac{1}{3}Bh \][/tex]
where V is the volume, B is the area of the base, and h is the height of the pyramid.
Given that the volume V is 0.734 cubic inches and the height h is 4.41 inches, we can rearrange the formula to solve for the area of the base B :
[tex]\[ B = \frac{3V}{h} \][/tex]
Substituting the given values:
[tex]\[ B = \frac{3 \times 0.734}{4.41} \] \[ B = \frac{2.202}{4.41} \] \[ B \approx 0.5 \text{ square inches} \][/tex]
Now, assuming the base is a square (since we are looking for the side length), the area of the base B is also equal to the side length squared:
[tex]\[ B = s^2 \][/tex]
where \( s \) is the side length of the base. Therefore:
[tex]\[ s^2 = 0.5 \][/tex]
Taking the square root of both sides:
[tex]\[ s = \sqrt{0.5} \] \[ s \approx 0.7071 \text{ inches} \][/tex]
The side length of the pyramid's base is approximately 0.7071 inches.
To determine if this number is rational or irrational, we consider the definition of rational numbers. A rational number is one that can be expressed as the quotient of two integers. The square root of 0.5 can be rewritten as:
[tex]\[ s = \sqrt{0.5} = \sqrt{\frac{1}{2}} = \frac{\sqrt{1}}{\sqrt{2}} = \frac{1}{\sqrt{2}} \][/tex]
To rationalize the denominator, we multiply the numerator and the denominator by [tex]\( \sqrt{2} \)[/tex]:
[tex]\[ s = \frac{1}{\sqrt{2}} \times \frac{\sqrt{2}}{\sqrt{2}} = \frac{\sqrt{2}}{2} \][/tex]
Since [tex]\( \sqrt{2} \)[/tex] is an irrational number, the side length s is also irrational because it cannot be expressed as the quotient of two integers.
