Let X, denote the weight of a randomly selected prepackaged one-pound bag of carrots. Of course, one pound bags of carrots won't weigh exactly one pound. In fact, history suggests that Xi is normally distributed with a mean of 1.18 pounds and a standard deviation of 0.07 pound. Now, let W denote the weight of randomly selected prepackaged three-pound bag of carrots. Three pound bags of carrots won't weigh exactly three pounds either. In fact, history suggests that Wis normally distributed with a mean of 3.22 pounds and a standard deviation of 0.09 pound. Selecting bags at random, what is the probability that the sum of three one-pound bags exceeds the weight of one three-pound bag?
Answer:
0.9830 = 98.30% probability that the sum of three one-pound bags exceeds the weight of one three-pound bag
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Three one pound bags:
3 one pound mags, which have mean 1.18 and standard deviation of 0.07. The mean is 1.18 multiplied by 3, and the standard deviation will be 0.07 multiplied by the square root of 3. So
[tex]\mu_{1} = 3*1.18 = 3.54[/tex]
[tex]\sigma_{1} = 0.07\sqrt{3} = 0.1212[/tex]
Three pound bags:
Mean 3.22, standard deviation 0.09. So
[tex]\mu_{2} = 3.22, \sigma_{2} = 0.09[/tex]
What is the probability that the sum of three one-pound bags exceeds the weight of one three-pound bag?
Here, we work with the subtraction of the normal variables. The mean is the subtraction of the means, and the standard deviation is the square root of the sum of the variances. So
[tex]\mu = \mu_{1} - \mu_{2} = 3.54 - 3.22 = 0.32[/tex]
[tex]\sigma = \sqrt{\sigma_{1}^2 + \sigma_{2}^2} = \sqrt{0.1212^2+0.09^2} = 0.151[/tex]
This is the probability of the subtraction being positive, that is, 1 subtracted by the pvalue of Z when X = 0. Then
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{0 - 0.32}{0.151}[/tex]
[tex]Z = -2.12[/tex]
[tex]Z = -2.12[/tex] has a pvalue of 0.0170
1 - 0.0170 = 0.9830
0.9830 = 98.30% probability that the sum of three one-pound bags exceeds the weight of one three-pound bag

A community drama centre sells tickets to a play, they sell 216 tickets. Adult tickets cost $10.25 and student tickets cost $8.00. The total ticket sales came to $2117.25. How many student tickets were sold? How many adult tickets were sold?
Answer: They sold 173 adult tickets and 43 student tickets.
Step-by-step explanation:
Equations:
10.25x + 8y = 2117.25x + y = 216X = adult tickets.Y = student tickets.Solving:
10.25x + 8(216 - x) = 2117.25 (y = 216 - x, substitute in for y)10.25x + 1728 - 8x = 2117.25 (distribute)2.25x = 389.25 (combine like terms)x = 173173 + y = 216 (solve for y)y = 43The graph below shows the number of paintballs a machine launches, y, in x seconds

Mariam is going to see a movie and is taking her 3 kids. Each movie ticket costs $12
and there are an assortment of snacks available to purchase for $3 each. How much
total money would Mariam have to pay for her family if she were to buy 6 snacks for
everybody to share? How much would Mariam have to pay if she bought x snacks for
everybody to share?
Answer:
a) $66
b) $48 + $3x
Step-by-step explanation:
4(12)=48
3(6)=18
48+18=66
---------------
4(12)=48
Each snack is $3, so is the bought x snacks, it would be $3x
She would pay $48 on movie tickets and $18 on snacks which would be a grand total of $66. If she bought x amount of snacks the equation would be 3x+48

Answer:
4.44444444444 or 40/9
Step-by-step explanation:
i searched it up
8 divided by 1 4/5 in fraction form will be 40 / 9. Then the faction number 40 / 9 in the decimal form will be 4.4444.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.
The mixed fraction number is converted into a faction number.
⇒ 1 4/5
⇒ 1 + 4/5
⇒ (5 + 4) / 5
⇒ 9/5
Then the quotient of the numbers 8 and 9/5 will be given as,
⇒ 8 / (9/5)
⇒ 8 x 5 / 9
⇒ 40 / 9
The faction number 40 / 9 in the decimal form will be 4.4444.

Full question isDaniel's age is 15% of Sara's. Luke's age is 75% of Sara's and Rachel's is 300% of Daniel's. When they added their ages, the total was 141. How old is Rachel? SolutionDaniel = d, Sara = s, Luke = l, Rachel = r
We get below relations:
d = 0.15sl = 0.75sr = 3d ⇒ r = 3*0.15s ⇒ r = 0.45sSum of ages:
d + s + l + r = 141Substitute and solve for s:
0.15s + s + 0.75s + 0.45s = 1412.35s = 141s = 141/2.35s = 60Rachel's age is:

2) y = –2x – 1
y = 3x – 16
Answer:
[tex]\left \{ {{x=3} \atop {y=-7}} \right.[/tex]
Step-by-step explanation:
We can directly substitute y of the first equation to the second equation.
-2x - 1 = 3x - 16
5x = 15
x = 3
Substituting back to any of the two equations, we get y = -2(3)-1 = -7. If you check with the second equation, y = 3(3)-16 = -7 as well.
Therefore [tex]\left \{ {{x=3} \atop {y=-7}} \right.[/tex].

What is obtuse triangle?"It is a triangle whose one of the angles measure greater than 90° and other two acute angles."
What is law of sines?"The ratio of the length of a side of a triangle to the sine of the angle opposite to that side is the same for all sides and angles in a given triangle."
For given question,
We have been given an obtuse triangle ABC.
Here, ∠B = 32°
∠C = 125°
We know that the sum of all angles of a triangle is 180°
⇒ ∠A + ∠B + ∠C = 180°
⇒ ∠A + 32° + 125° =180°
⇒ ∠A = 23°
Using the law of sines to triangle ABC,
[tex]\Rightarrow \frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC} \\\\\Rightarrow \frac{7}{sin23^{\circ}} =\frac{b}{sin32^{\circ}} =\frac{c}{sin125^{\circ}}[/tex]
Consider,
[tex]\Rightarrow \frac{7}{sin23^{\circ}} =\frac{b}{sin32^{\circ}} \\\\\Rightarrow \frac{7}{0.39} =\frac{b}{0.53} \\\\\Rightarrow 7\times 0.53=b\times 0.39\\\\\Rightarrow b = 9.5[/tex]
Now we find the length of the side AB.
[tex]\Rightarrow \frac{7}{sin23^{\circ}} =\frac{c}{sin125^{\circ}} \\\\\Rightarrow \frac{7}{0.39} =\frac{c}{0.82} \\\\\Rightarrow 7\times 0.82=c\times 0.39\\\\\Rightarrow c = 14.72[/tex]
Therefore, the missing values are:
A = 23°
b = 9.5
c = 14.72
