What is the surface area of the given figure?
A.2,520 cm2
B.2,792 cm2
C.4,080 cm2
D.2,280 cm2
Answers
Answer:
D. 2,280 cm²
Step-by-step explanation:
Surface area of triangular prism = bh + (S1 + S2 + S3)*L
Where,
b = 24 cm
h = 10 cm
S1 = 26 cm
S2 = 24 cm
S3 = 10 cm
L = 34 cm
Plug in the values
Surface area = 24*10 + (26 + 24 + 10)*34
= 240 + 2,040
= 2,280 cm²

For estimation purposes, the shape formed by the sectors is considered to be a parallelogram. Which statement is true?
Answers
Answer:
A
Step-by-step explanation:
Just took the test
The statement that asserts a true claim would be:
A). The height is approximately r units and the base length is approximately πr units.
What is the sector?The sector is described as an element of the circle or a part that extends to the center.
In the given figure, the height of the congruent sectors would be equivalent to r units as the radius is r units.
While the length of its base would be equivalent to πr units to denote the base length.

A ferry began its journey at 08 00 and travelled 208 km towards its destination.
The average speed of the ferry was 32 km/h. What time did the ferry reach its
destination?
please help
Answers
answer:
14 30
Step-by-step explanation:
208/32=6.5
6.5 hours is 6 hours 30 min
08 00 + 6h 30min =14 30/2.30
The ferry reached its destination at approximately 14:30 or 2:30 PM.
To determine the time the ferry reached its destination, we need to divide the distance traveled by the average speed of the ferry.
Distance traveled = 208 km
Average speed = 32 km/h
Time = Distance / Speed
Time = 208 km / 32 km/h
Calculating this, we find:
Time = 6.5 hours
Since the ferry started its journey at 08:00, we can add 6.5 hours to that time to determine the arrival time.
08:00 + 6.5 hours = 14:30
Therefore, the ferry reached its destination at approximately 14:30 or 2:30 PM.

Six measurements were made of the magnesium ion concentration (in parts per million, or ppm) in a city's municipal water supply, with the following results. It is reasonable to assume that the population is approx. normal.
DATA: 202, 164, 157, 177, 113, 213202, 164, 157, 177, 113, 213.
Based on a 98% confidence interval for the mean magnesium ion concentration, is it reasonable to believe that the mean magnesium ion concentration may be greater than 195?
Answers
Answer:
The 98% confidence interval for the mean magnesium ion concentration is between 122 ppm and 220 ppm. As the lower bound of the interval is below 195, it is not reasonable to conclude that the mean magnesium ion concentration may be greater than 195
Step-by-step explanation:
The six measurements are:
202, 164, 157, 177, 113, 213
Sample mean:
Sum of all values divided by the number of values which is 6. So
[tex]S_m = \frac{202+164+157+177+113+213}{6} = 171[/tex]
Sample standard deviation:
Square root of the difference squared between each value and the mean, and divided by 1 subtracted by the sample size. So
[tex]s = \sqrt{\frac{(202-171)^2+(164-171)^2+(157-171)^2+(177-171)^2+(113-171)^2+(213-171)^2}{5}} = 35.69[/tex]
Confidence interval
We have the standard deviation for the sample, which means that the t-distribution will be used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 6 - 1 = 5
98% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 5 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.98}{2} = 0.99[/tex]. So we have T = 3.365
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 3.365\frac{35.69}{\sqrt{6}} = 49[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 171 - 49 = 122 ppm
The upper end of the interval is the sample mean added to M. So it is 171 + 49 = 220 ppm
The 98% confidence interval for the mean magnesium ion concentration is between 122 ppm and 220 ppm. As the lower bound of the interval is below 195, it is not reasonable to conclude that the mean magnesium ion concentration may be greater than 195

Answers
Answer:
A) 0.01
B) 0.07
Step-by-step explanation:
We are given;
P(accidents last year) = 0% = 0
P(accidents this year) = 6% = 0.06
P(accidents last year | accidents this year) = 10% = 0.1
A) We want to find the percentage of the employees will experience lost-time accidents in both years.
From multiplication rule in probability, we know that;
P(A & B) = P(A) × P(B|A) = P(B) × P(A|B)
Thus;
P(accident in both years) = P(accidents this year) × P(accidents last year | accidents this year)
P(accident in both years) = 0.06 × 0.1
P(accident in both years) = 0.006
To 2 decimal places gives; 0.01
B) from the addition rule, we know that;
P(A or B) = P(A) + P(B) - P(A & B)
Thus;
P(accident last year or this year) = P(accidents last year) + P(accidents this year) - P(accident in both years)
P(accident last year or this year) = 0 + 0.06 + 0.006 = 0.066
To 2 decimal places = 0.07
