Answer:
a. 28π m²
b. 44π m²
Step-by-step explanation:
a. Lateral surface of the cone = πrl
Where,
r = 4 m
l = 7 m
Lateral surface area = π*4*7 = 28π m²
b. Surface area of cone = πr(l + r)
r = 4 m
l = 7 m
Surface area = π*4(7 + 4)
= 4π(11)
= 44π m²
Lloyd's Cereal company packages cereal in 1 pound boxes (16 ounces). A sample of 49 boxes is selected at random from the production line every hour, and if the average weight is less than 15 ounces, the machine is adjusted to increase the amount of cereal dispensed. If the mean for 1 hour is 1 pound and the standard deviation is 0.2 pound, what is the probability that the amount dispensed per box will have to be increased
Answer:
0.0143 = 1.43% probability that the amount dispensed per box will have to be increased
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean for 1 hour is 1 pound and the standard deviation is 0.2 pound
This means that [tex]\mu = 1, \sigma = 0.2[/tex]
Sample of 49:
This means that [tex]n = 49, s = \frac{0.2}{\sqrt{49}} = 0.0286[/tex]
What is the probability that the amount dispensed per box will have to be increased?
This is the probability of the sample mean being less than 15 pounds = 15/16 = 0.9375 ounces, which is the pvalue of Z when X = 0.9375.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.9375 - 1}{0.0286}[/tex]
[tex]Z = -2.19[/tex]
[tex]Z = -2.19[/tex] has a pvalue of 0.0143
0.0143 = 1.43% probability that the amount dispensed per box will have to be increased

What is the conditional relative frequency of a state's popular vote being won by the Democrat in 2012, given that it was won by the Democrat in 1976?
The frequency data table is missing, so i have attached it.
Answer:
0.5
Step-by-step explanation:
We want to find conditional relative frequency and conditional relative frequency is used to compare the frequency count to the marginal total that represents the particular condition we are dealing with.
In this case, the condition is the popular vote of the state being won by the Democrat in 2012, given that the same popular vote was won by the Democrat in 1976.
In the frequency data table attached, we see that the joint frequency count for Democrat winning in 1976 and 2012 is given as 12.
While the corresponding marginal frequency total is given as 24.
Thus;
Conditional relative frequency = joint frequency count/marginal frequency total = 12/24 = 0.5
The conditional relative frequency of a state's popular vote being won by the Democrat in 2012, given that it was won by the Democrat in 1976:
We need to discover conditional relative recurrence and conditional relative recurrence is utilized to compare the recurrence number to the minimal add up to that speaks to the specific condition we are managing with. In this case, the condition is the prevalent vote of the state being won by the Democrat in 2012, given that the same prevalent vote was won by the Democrat in 1976. In the recurrence information table joined, we see that the joint recurrence check for Democrat winning in 1976 and 2012 is given as 12.
Thus;
Conditional relative frequency = joint frequency count/marginal frequency total = 12/24 = 0.5
The conditional relative frequency of a state's popular vote being won by the Democrat in 2012, given that it was won by the Democrat in 1976 is 0.5.

Find the Mean Absolute Deviation: (MAD)
10, 9, 3, 8, 10.
Answer: Hey there !! The answer is 2.
Step-by-step explanation:
The mean absolute deviation of a dataset is the average distance between each data point and the mean.
The absolute mean deviation is 2.
What is mean absolute deviation?The mean absolute deviation of a dataset is the average distance between each data point and the mean.
We have,
10, 9, 3, 8, 10
We first find the mean of 10, 9, 3, 8, 10
Mean = (10 + 9 + 3 + 8 + 10) / 5
Mean = 40 /5 = 8
Data sets
10 | 10 - 8 | 2
9 | 9 - 8 | 1
3 | 3 - 8 | 5
8 | 8 - 8 | 0
10 | 10 - 8 | 2
Mean absolute deviation
= (2 + 1 + 5 + 0 + 2) / 5
= 10 / 5
= 2
Thus the absolute mean deviation is 2.

Step-by-step explanation:
help please ! order the side lengths GH , HI , IG from least to greatest
Answer:
IH < IG < HG
Step-by-step explanation:
To solve this equation remember that angle measurements correspond with sides. So, the largest angle will be opposite of the longest side and the smallest angle will be opposite of the shortest side.
First, you need to find m<I; do this by subtracting 52 and 45 from 180. This means that m<I=83, making it the largest angle. Therefore, the angles, in order of least to greatest, are <G, <H, <I. So, to find the final answer, find the sides opposite of each of the angles. This means the answer is IH < IG < HG.

In order for a relationship to be proportional it must follow these requirements:
It must have a constant rate of changeIt must go through the origin (0,0)The equation is put in y = kx form (where k = slope)Knowing this let us now look at each relationship
The first one indeed has a constant rate of change
However it has a y intercept of (1,0) so it doesn't go through the origin therefore it is not a proportional relationship
For B:
B is not a proportional relationship because it does not have a constant rate nor can we tell if it goes through he origin
The y value first adds by 7 then by 9 then by 6. (while the x value goes up 1)
in a constant rate of change relationship the slope is constant and goes up by a certain amount each time therefore relation b is not proportional
For C:
Like relation A it has a constant rate of change but its not put in y = kx form and has a y intercept. Because of this it is not considered a proportional relationship
For D:
Relation D happens to have a constant rate of change (as it has a vertical straight line). It also happens to pass through the origin (0,0)
The relation fulfills each requirement therefore D is your answer

11 in
11 in
Answer:
576.4 in²
Step-by-step explanation:
Surface area of square pyramid = Base Area + ½(perimeter of base)(slant height)
Base area = s² = 11² = 121 in.²
Perimeter of base = 4(11) = 44 in.
Slant height = 20.7 in.
Plug in the values
Surface area = 121 + ½(44)(20.7)
= 576.4 in²
