He cafeteria at Midtown Middle School surveyed 575 students about their favorite food. If 8% of the students surveyed liked chicken, how many students said that chicken is their favorite food?
Answer:
46.08 students said that chicken is their favorite food.
Step-by-step explanation:
Let X denote the number of students who liked chicken.
The proportion of students who liked chicken is, p = 0.08.
About n = 576 students were surveyed about their favorite food.
Every student's answer was independent of the others.
Thus, the random variable X follows a binomial distribution with parameters n = 576 and p = 0.08.
The probability mass function of X is:
[tex]P(X=x)={576\choose x}(0.08)^{x}(1-0.08)^{576-x};\ x=0,1,2,3...576[/tex]
Then expected number of students who said that chicken is their favorite food is:
[tex]E(X)=np\\\\=576\times0.08\\\\=46.08[/tex]
Thus, 46.08 students said that chicken is their favorite food.

Answer:7.62, if not just 7.6 orr 58 read explanation lol
Step-by-step explanation:
i did the math and i doubled checked on a calculator :P,
cause you use the formula c= [tex]\sqrt{a^2+ b^2}[/tex] and in this case a^2 and b^2 is 3^2 and 7^2 and then you solve so its 9 and 49 and then add them which is 58 and then you find the square root of 58 which is 7.6 or in your case you put 58 under the square root

find the length of side BD round your answer to the nearest hundred
Answer:
The length of side BD is 4.62 units to the nearest hundredth
Step-by-step explanation:
In Δ ABC
∵ m∠ABC = 90°
∵ BD ⊥ AC
∴ AB × BC = BD × AC
∵ AB = 12 units
∵ BC = 5 units
∵ AC = 13 units
→ Substitute them in the equation above
∴ 12 × 5 = BD × 13
∴ 60 = 13 BD
→ Divide both sides by 13 to find BD
∴ 4.615384615 = BD
→ Round it to the nearest hundredth
∴ BD = 4.62 units
∴ The length of side BD is 4.62 units to the nearest hundredth

1. -2x = -8
2. -2x - 4 = -18
3. 3 (x -4) = -18
4. (X-5) = -7
5. 2 (2x-4) = -16
Answer:
1. x=4
2. x=7
3. x=-2
4. x=-2
5. x=-3
Step-by-step explanation:
1. Divide both sides by -2 to get x by itself
-2x/-2=-8/-2....
x=4
2. Add 4 to both sides and then divide by -2
-2x-4+4=-18+4
-2x/-2=-14/-2
x=7
3. Distribute, add 12 to both sides and then divide by 3
3x-12=-18
3x-12+12=-18+12
3x/3=-6/3
x=-2
4. Add 5 to both sides
x-5+5=-7+5
x=-2
5. Distribute, add 4 to both sides, divide both sides by 4
4x-4=-16
4x-4+4=-16+4
4x/4=-12/4
x=-3

divide 4 throughout:
x^2 + 5 = 0
x^2 = -5
x = ±√-5
However, you can't square root a negative number as it is a complex number / imaginary number hence you would want to conclude it as "no solution"

The equation that represents the situation is 12 - 4x = 24. Then the solution of the equation will be negative 3.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
When 12 is subtracted from 4 times a number, the result is 24.
Let the number be 'x'. Then the equation is given as,
12 - 4x = 24
Simplify the equation, then we have
12 - 4x = 24
- 4x = 24 - 12
- 4x = 12
4x = - 12
x = - 12 / 4
x = - 3
The equation that represents the situation is 12 - 4x = 24. Then the solution of the equation will be negative 3.

Step-by-step explanation:
Answer:
[tex]f(-8)=-2[/tex]
Step-by-step explanation:
We have the function:
[tex]f(x)=\frac{x}{4}[/tex]
And we want to find f(-8).
So, simply substitute -8 for x. This yields:
[tex]f(-8)=\frac{-8}{2}[/tex]
Divide:
[tex]f(-8)=-2[/tex]
Hence, our answer is -2.
