Step-by-step explanation:
The angle of elevation from Nathan to a lighthouse is 74°.
If the lighthouse is 112 feet tall, how far is Nathan from the
base of the lighthouse?
Answer:
Nathan is 36.3910059 ft from the base of the lighthouse.
Step-by-step explanation:
So to find the base, you have to find the tan (both legs) of the right triangle that the lighthouse makes. The angle of Nathan to the lighthouse is 74° so to find the distances, you have to do the tan(72) = opp/adj
The opposite is 112, and we have to find the adjacent.
tan(72) = 112/adj
3.07768354 = 112/adj
adj = 112/3.07768354
adj = 36.3910059

The following data shows the weight, in pounds, of 5 boxes:
3, 1, 2, 2, 2
What is the value of the mean absolute deviation of the weight of the boxes, and what does it represent about the weight of a box?
(A.) 0.4 pound; on average, the weight of a box varies 0.4 pounds from the mean of 2 pounds
(B.) 0.8 pound; on average, the weight of a box varies 0.8 pounds from the mean of 2 pounds
(C.) 0.4 pound; the weight of 50% of the boxes is greater than 0.4 pound
(D.) 0.8 pound; the weight of 50% of the boxes is greater than 0.8 pound
Answer:
c is the answer
Step-by-step explanation:
Answer:
Step-by-step explanation:
First put the numbers from least to greatest: 1, 2, 2, 2, 3 2 is the mean.
Then you determine the distance each data value is from the mean.
1, 2, 2, 2, 3
1, 0, 0, 0, 1
Calculate the mean of the distances: 1 + 0 + 0 + 0 + 1 = 2
Then divide: 2 divided by 5 = 0.4
So your answer is 0.4 pound; on average, the weight of a box varies 0.4 pounds from the mean of 2 pounds

Given that £1 = $1.62
b)
a) How much is £650 in $?
b) How much is $405 in £?
Answer:
A) £650 = $1053
B) $405 = £250
Step-by-step explanation:
For a) Since £1 is equal to $1.62 you would just do £650 times 1.62 to get $1053
For b) Since £1 is equal to $1.62 you would do $405 divided by 1.62 to get £250

DLMN is a quadrilateral inscribed in a circle. If mÐD = 84° and mÐN = 74°, find mÐL.
9514 1404 393
Answer:
angle L = 106°
Step-by-step explanation:
Opposite angles in an inscribed quadrilateral are supplementary.
∠L = 180° -∠N
∠L = 180° -74° = 106°
Solve using the tangent formula(real answers only please)
9514 1404 393
Answer:
21.07
Step-by-step explanation:
The tangent ratio is ...
Tan = Opposite/Adjacent
For the given values, this is ...
tan(36°) = x/29
Solving for x, we have ...
x = 29·tan(36°)
x ≈ 21.07
A report on the nightly news broadcast stated that 10 out of 108 households with pet dogs were burglarized and 20 out of 208 without pet dogs were burglarized. Suppose that this data is used to test the claim that the proportion of households with dogs that are burglarized is the same as the proportion of households without dogs that are burglarized. What would be the test statistic for this test
Answer:
The answer is "0.9184".
Step-by-step explanation:
This problem is assisted by data analysis:
Its overview hypothesis test to two sample proportions:
[tex]p_1 :[/tex]percentage of population contributions 1
[tex]p_2:[/tex]percentage of population contributions 2
[tex]\to p_1 - p_2:[/tex] proportion difference
[tex]\to H_0 : p_1 - p_2 = 0\\\\\to H_A : p_1 - p_2 ? 0[/tex]
Calculating the Hypothesis test values:
[tex]Diff \ \ Count1 \ \ Total1 \ \ Count2 \ \ Total2 \ \ Sam. Diff. \ \ Std. Err.\ \ Z-Stat \ \ P value\\\\[/tex]
[tex]p_1 - p_2\ \ 10\ \ 108\ \ 20\ \ 208\ \ -0.0035612536\ \ 0.034766147\ \ -0.10243452 \ \ 0.9184[/tex]
So, the [tex]P - value = 0.9184[/tex]
