everybody to share?
Total cost with 3 snacks: ?
Total cost with 2 snacks: ?
Answers
Answer:
Total cost with 3 snacks: 15
Total cost with 2 snacks: 10
Step-by-step explanation:
5x3=15
5x2=10
Total Cost with 3 snacks = $75
Total Cost with 2 snacks = $70
What is total cost?"Total cost, in economics, the sum of all costs incurred by a firm in producing a certain level of output. It is typically expressed as the combination of all fixed costs."
Amelia's family have 3kids and Amelia herself= 4 people
We have,
Each movie ticket=$13
Each snack item = $5
∴ Amount of Tickets = \(4\)×\(15\) = $60
Total Cost with 3 snacks = Amount of Tickets + cost of snacks
Total Cost with 3 snacks = Amount of Tickets + \(3\)×\(5\)
=$60+$15
=$75
Total Cost with 2 snacks = Amount of Tickets + cost of snacks
Total Cost with 2 snacks= Amount of Tickets + \(2\)×\(5\)
=$60+$10
=$70
Hence, Total Cost with 3 snacks = $75
Total Cost with 2 snacks = $70

Find the indicated quantity, given u = (−5, − 8), v = (3, −2). Step
2 of 4: Find 5u * v.
Answers
The value of 5u * v is 5.
Given vectors: u = (-5, -8) and v = (3, -2).
5u = 5(-5, -8) = (-25, -40)
Now, we will find the dot product of 5u and v:
5u . v = (-25, -40) . (3, -2)
Multiplying the corresponding components and adding, we get:
5u . v = (-25 × 3) + (-40 × -2)5u . v = -75 + 80
Therefore,5u . v = 5

(b) Yes, the experiment has a control group.
(c) The treatments can be randomly assigned to the experimental units by randomly selecting 20 containers and assigning each of the four treatments to 5 containers.
a) Treatments: Four different concentrations of fungus mixtures (0 ml/L, 1.25 ml/L, 2.5 ml/L, and 3.75 ml/L).
Experimental units: 20 individual containers with a group of insects.
Response variable: Number of insects that are still alive in each container one week after spraying.
(b) A control group is used to compare the results of the treatment group to a group that is not exposed to the treatment.
In this experiment, the control group can be the group of insects that are not exposed to any of the fungus mixtures.
c) The treatments can be randomly assigned to the experimental units by randomly selecting 20 containers and assigning each of the four treatments to 5 containers.
This way, each treatment has the same number of units and the assignment of treatments to units is random, which reduces the risk of bias in the experiment.

express
the speed
10m
per second as
km per hour
Answers
10 m/s can be expressed as 36km/h.
Here, we are given an expression for speed, that is: 10 meter per second.
Now, as per the rules of mathematics,
1 kilometer = 1000 meters
⇒ 1 meter = 1/1000 kilometers
or 1 meter = 0.001 kilometers
and also, 1 hour = 60 mins
and 1 min = 60 seconds
⇒ 60 mins = 60 × 60 seconds
= 3600 seconds
Thus, 1 hour = 60 mins = 3600 seconds
⇒ 1 second = 1/3600 hours
Now, we need to convert meter per second into kilometer per hour,
1 meter/ 1 second = \(\frac{0.001}{\frac{1}{3600} }\)
= (0.001 × 3600)/ 1
= 3.6
This 1 meter per second = 3.6 kilometer per hour
⇒ 10 meter per second = 3.6 × 10 = 36 kilometers per hour
Thus, 10 m/s is 36km/h.

standard labor-hours per unit of output 8.5 hours standard labor rate $12.30 per hour the following data pertain to operations concerning the product for the last month: actual hours worked 6,300 hours actual total labor cost $74,970 actual output 800 units
Answers
Direct labor efficiency variance = $6,100 F.
Given that
Standard labor-hours per unit of output 8.5 hours
Standard labor rate $12.30 per hour
Standard labor hours allowed 6,800 hours (800 units * 8.5 hours allowed)
The following data pertain to operations concerning the product for the last month:
Actual hours worked 6,300 hours
Actual total labor cost $74,970
Actual output 800 units
We can determine the labor efficiency variance using the following equation:
1. Direct labor efficiency variance = (Standard hours allowed - Actual labor hours) * Standard rate
2. Direct labor efficiency variance = (6,800 hours - 6,300 hours) * $12.20
3. Direct labor efficiency variance = $6,100 F
The variance is favorable as the actual labor hours used are less than the standard hours allowed.
Hence the answer is Direct labor efficiency variance = $6,100 F.

The scores for the Algebra 2 CFE are normally distributed with a mean score of 43 and
a standard deviation of 3.8. If you scored 47 on the test, what percentage of test takers
scored lower than you? Do not round your answer. [percent]
Answers
Answer:
85.375%
Step-by-step explanation:
We would be using the z-score formula which is
z = (x-μ)/σ, where
x is the raw score,
μ is the population mean, and
σ is the population standard deviation.
In the question, we are given:
x is the raw score = 47
μ is the population mean = Mean score = 43
σ is the population standard deviation = 3.8
z = (x-μ)/σ
z = (47- 43)/ 3.8
z = 4/3.8
z = 1.0526315789
The z score = 1.0526315789
Checking my z score on my normal distribution table,
The percentage of test takers that scored lower than you =
[1 - P(x>Z)] × 100
= ( 1 - 0.14625) × 100
= 0.85375 × 100
= 85.375%
Therefore, the percentage of test takers that scored lower than you is 85.375%

Answers
The median represents the middle value of the data 5.8 feet will be the middle value.
What is the median?The median represents the middle value in a dataset. The median is important because it gives us an idea of where the center value is located in a dataset. The median tends to be more useful to calculate than the mean when a distribution is skewed and/or has outliers.
Given that apod of dolphins contains 800 dolphins of different ages and lengthens. The median length of dolphins in this pod is 5.8 feet.
From the definition, we can see that of the 800 dolphins the length of the middle dolphin is 5.8 feet because it is a median and the upper values will be greater than 5.8 feet and below it all the dolphins will have smaller lengths.

True. It is possible for a small treatment effect to still be statistically significant if the sample size is large enough.
We have,
Statistical significance is determined by the p-value, which measures the probability of obtaining the observed results if the null hypothesis (no difference between groups) is true.
A small treatment effect may still produce a low p-value if the sample size is large enough to detect even small differences.

Linear equations in one variable
The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
For example, 2x+3=8 is a linear equation having a single variable in it.
Let x should be subtracted from the sum of ( 5/6 + -2/3 ) to get 3/4
Therefore
[ 5/6 + (-2/3 ] - x = 3/4
⇒ ( 5/6 - 2/3) - x = 3/4
⇒ ( 5/6 - 4/6) - x = 3/4
⇒ 1/6 - x = 3/4
⇒ x = 1/6 - 3/4
⇒ x = 4/24 - 18/24
⇒ x = -14/24

Answer:
If it is asking for the angle then it is 68 degrees
Step-by-step explanation:
Since lines AR and AC are the same that means angle A and C are the same, in which you make the equation 3x+23=5x+1 and solve that resulting in x = 11. From there you plug in 11 to get angle A and C equaling 56, so 56+56=112. Then from there you subtract 180-112 to get 68 degrees.
Yes.
The given triangle ️ ARC is an isosceles triangle (it's given that the sides AR = RC). If 2 opposite sides are equal then the 2 opposite angles will also be equal.
So,
A = C
=》3x + 23 = 5x + 1
Using this,
3x + 23 = 5x + 1
3x - 5x = 1 - 23
-2x = -22
x = -22/-2
x = 11
Measure of A = 3x + 23
= 3(11) + 23
= 33 + 23
= 56°
Measure of C = Measure of A = 56°
Now,
R = ?
R = 180 - (A + R) [Angle Sum Property]
R = 180 - (56 + 56)
R = 180 - 112
R = 68°
