The 8th grade class sold snacks at lunch to earn money for a field trip. They sold 30 items this week. For each snack type, what percentage of all snacks sold were of that type? Round to the nearest hundredth if necessary.
Answer:
Step-by-step explanation:
Total number of snacks sold by 8th grade class = 30
Percentage of a particular snack sold = [tex]\frac{\text{Number of particular snack sold}}{\text{Total number of all snacks sold}} \times 100[/tex]
Percentage of cookies sols = [tex]\frac{6}{30}\times 100[/tex] = 20%
Percentage of cheese sticks sold = [tex]\frac{8}{30}\times 100[/tex]
= 26.67%
Percentage of chips sold = [tex]\frac{12}{30}\times 100[/tex]
= 40%
Percentage of water sold = [tex]\frac{4}{30}\times 100[/tex]
= 13.33%
The probability that a randomly selected 2 2-year-old male garter snake garter snake will live to be 3 3 years old is 0.98861 0.98861. (a) What is the probability that two randomly selected 2 2-year-old male garter snake garter snakes will live to be 3 3 years old? (b) What is the probability that seven seven randomly selected 2 2-year-old male garter snake garter snakes will live to be 3 3 years old? (c) What is the probability that at least one of seven seven randomly selected 2 2-year-old male garter snake garter snakes will not live to be 3 3 years old? Would it be unusual if at least one of seven seven randomly selected 2 2-year-old male garter snake garter snakes did not live to be 3 3 years old?
Answer:
a. [tex]Probability = 0.97735[/tex]
b. [tex]Probability = 0.92294[/tex]
c. [tex]P(At\ Least\ One) = 1[/tex]
No, it is not unusual if at least 1 lives up to 3.
Step-by-step explanation:
Given
Represent the probability that a 2 year old snake will live to 3 with P(Live);
[tex]P(Live) = 0.98861[/tex]
Solving (a): Probability that two selected will live to 3 years.
Both snakes have a chance of 0.98861 to live up to 3 years.
So, the required probability is:
[tex]Probability = P(Live)\ and\ P(Live)[/tex]
[tex]Probability = 0.98861 * 0.98861[/tex]
[tex]Probability = 0.9773497321[/tex]
[tex]Probability = 0.97735[/tex] --- Approximated
Solving (b): Probability that seven selected will live to 3 years.
All 7 snakes have a chance of 0.98861 to live up to 3 years.
So, the required probability is:
[tex]Probability = P(Live)^n[/tex]
Where [tex]n = 7[/tex]
[tex]Probability = 0.98861^7[/tex]
[tex]Probability = 0.92294324145[/tex]
[tex]Probability = 0.92294[/tex] --- Approximated
Solving (c): Probability that at least one of seven selected will not live to 3 years.
In probabilities, the following relationship exist:
[tex]P(At\ Least\ One) = 1 - P(None).[/tex]
So, first we need to calculate the probability that none of the 7 lived up to 3.
If the probability that one lived up to 3 years is 0.98861, then the probability than one do not live up to 3 years is 1 - 0.98861
This gives:
[tex]P(Not\ Live) = 0.01139[/tex]
The probability that none of the 7 lives up to 3 is:
[tex]P(None) = P(Not\ Live)^7[/tex]
[tex]P(None) = 0.01139^7[/tex]
Substitute this value for P(None) in
[tex]P(At\ Least\ One) = 1 - P(None).[/tex]
[tex]P(At\ Least\ One) = 1 - 0.01139^7[/tex]
[tex]P(At\ Least\ One) = 0.99999999999997513055642436060443621[/tex]
[tex]P(At\ Least\ One) = 1[/tex] ---- Approximated
No, it is not unusual if at least 1 lives up to 3.
This is so because the above results, which is 1 shows that it is very likely for at least one of the seven to live up to 3 years
(45x-7)4x=57 solve this and ill make out with you
Answer:
After solving [tex](45x-7)4x=57[/tex] we get [tex]\mathbf{x=0.645 \ or \ x = -0.490}[/tex]
Step-by-step explanation:
We need to solve the equation: [tex](45x-7)4x=57[/tex]
Solving:
[tex](45x-7)4x=57[/tex]
Multiply 4x with terms inside the bracket
[tex]180x^2-28x=57[/tex]
[tex]180x^2-28x-57=0[/tex]
We need to solve above equation to find value of x
Using quadratic formula for finding value of x: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
We have a=180, b=-28 and c=-57
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-(-28)\pm\sqrt{(-28)^2-4(180)(-57)}}{2(180)}\\x=\frac{28\pm\sqrt{784+41040}}{360}\\x=\frac{28\pm\sqrt{41824}}{360}\\x=\frac{28\pm204.51}{360}\\x=\frac{28+204.51}{360} \ or \ x=\frac{28-204.51}{360}\\x=0.645 \ or \ x = -0.490[/tex]
Values of x are [tex]\mathbf{x=0.645 \ or \ x = -0.490}[/tex]
So, After solving [tex](45x-7)4x=57[/tex] we get [tex]\mathbf{x=0.645 \ or \ x = -0.490}[/tex]
I need help please
Answer:
m<L.F.M = 50
Step-by-step explanation:
So we know that the m<F.M.L = 90 and m<F.M.P = 90 so...
3x- 1 + 2x + 6 = 90 (collect like terms)
5x + 5 = 90 (subtract 5 on both sides)
5x = 85 (divide by 5 on both sides)
x = 17
Plug in to (3x-1)
3(17) - 1 = m<L.F.M
50 = m<L.F.M

What is the constant
rate of change?
y = 5 – 17x
Answer:
-17
Step-by-step explanation:
The constant rate of change of a line is always the SLOPE. In the equation
y = mx + b, m represents the constant rate of change.
The constant rate of change from this equation is -17 because it's the slope.

What is the value of x?
Enter your answer in the box.
Answer:
35
Step-by-step explanation:
Since all the angles are the same in this triangle, all the sides should be the same too.
Hence, 3x - 5 = 4x - 30
5 + -1x = -30
-1x = -35
x = 35

Answer:
Considering the fact that this is an equilateral triangle, x would equal 25
Step-by-step explanation:
since in an equilateral triangle all sides are equal, just pick 2 and solve for x
3x-5=2x+20
3x-2x=20+5
x=25
to check work,
4(25)-30=70

Sally leaves her house and jogs along a straight road. After one hour she has gone 4 miles. Then, Sally slows to a brisk walk at a constant rate. After the first hour of walking in the same direction, Sally is 6.5 miles from her house. How many miles from her house will she be after two more hours of walking?
Answer:
I'm pretty sure its 11.5
Answer:
11.5 mi.
Step-by-step explanation:
First, you figure out how much miles Sally has gone by walking.
6.5-4=2.5 mi.
You use the distance formula: d(distance)=r(rate)xt(time)
2.5 mi.=Rx1 hr.
rate=2.5 mi/hr.
To figure out how many miles Sally will be from her house after two more hours of walking, you use the distance formula again.
d=2.5mi/hrx2 hr.
d=5.0 mi(2.5x2)
6.5mi+5.0mi=11.5 mi total

Please help 15 points available! What is the equation of the line that is perpendicular to y - 3 x = 2 and that passes through (6,1)?
y = 1/3x - 1
y = 1/3x + 3
y = -1/3x + 3
y = -1/3x - 1
Answer:
C) y = -1/3x + 3
Step-by-step explanation:
y - 3x = 2
+ 3x + 3x
y = 3x + 2
find the reciprocal of the slope (3) which is -1/3 so -1/3 will be the slope for the perpendicular line
y = (-1/3)x + b
now find the y-intercept (b)
(6,1) x = 6 y = 1
y = (-1/3)x + b
1 = (-1/3)6 + b
1 = -2 + b
+2 +2
3 = b
y = (-1/3)x + 3

If you travel 2.2 miles in 30 minutes. How many miles did you travel in 12 minutes?
Let m = miles traveled in 12 minutes.
2.2/m = 30/12
Cross-multiply here.
30m = (2.2)(12)
30m = 26.4
m = 26.4 ÷ 30
m = 0.88
In 12 minutes, 0.88 miles is traveled.

Answer:
8 over 3
Step-by-step explanation:
Use
Y2 - y1 over x2 - x1 slop formula
Answer:
the slope in fraction form is 8/3, in integer form is 8.
Step-by-step explanation:
use the x coordinates for the run and the y coordinates for the rise. To find the rise you use the y coordinates -6 and 2, and think about how many spaces away they are on the coordinate plane by adding them both like they are positive. 6 + 2 = 8. To find the run, subtract 7 from 4 which equals 3. So, there you have the rise over run = 8/3 or in integer form, 8.
