In a room at a museum, we want to tile the floor. If the floor measures 15 feet by 55 feet, what is the largest-size square tile that we can use to tile the floor without having to cut tiles?
A) 11 ft by 11 ft
B) 5 ft by 11 ft
C) 5 ft by 3 ft
D) 3 ft by 3 ft
E) 11 ft by 3 ft
F) 5 ft by 5 ft
Answers
Answer:
B. 5 foot by 11 foot
the numbers have to be divisible in both directions.
11x11 doesn't work, because at 15 feet wide one tile isn't wide enough, and 2 is too wide.
5x11 works- 3x5= 15 and 11x5=55. you'd use 15 tiles.
the rest are all smaller.

Suppose you're hiring a new worker for your business. You'd like someone reliable. Suppose you use administer a test to job-seekers many other employers use to determine if applicants have this trait. The test is 90% senstitive and 95% specific. If 60 unreliable people apply and 20 reliable people apply, how many positive results will you have
Answers
Answer:
You will have 21 positive results.
Step-by-step explanation:
Sensitivity of test:
Is the true positive rate, that is, the proportion of positive results that give positive tests.
Specificity of test:
True negative rate, that is, the proportion of negative results that give negative tests.
90% sensitive, 20 reliable people apply
0.9*20 = 18
95% specific, 60 unreliable people apply
1 - 0.95 = 0.05 of positive results.
0.05*60 = 3
How many positive results will you have?
18 + 3 = 21
You will have 21 positive results.

if 9% of the air leaks out of brian bicycle tire everyday, what percent of the air will be left after 3 days. after a week. round your percent to 2 decimal places
Answers
Answer:
3 days = 75.36%1 week = 51.68%Step-by-step explanation:
You can use the future value formula to calculate this:
Future value = Amount * (1 + rate)^ no. of periods
As there is no given amount, simply calculate using (1 + rate)^ no. of periods.
After 3 days:
= (1 + (-9%))³
= 0.753571
= 75.36%
After a week:
Week = 7 days
= ( 1 + (-9%))⁷
= 0.51676

Measure of DEFACTS TO KNOW BEFORE SOLVING :-
The midsegment of a triangle is a line constructed by connecting the midpoints of any two sides of the triangle.The Triangle Midsegment Theorem tells us that a midsegment is one-half the length of the third side (the base), and it is also parallel to the base.PROCEDURE :-
According to Triangle Midsegment Theorem ,
[tex]DE = \frac{AC}{2}[/tex]
[tex]=> 4x + 4 = \frac{x + 36}{2}[/tex]
Multiplying 2 on both the sides ,
[tex]=> 2(4x + 4) = x + 36[/tex]
[tex]=> 8x + 8 = x + 36[/tex]
[tex]=> 8x - x = 36 - 8[/tex]
[tex]=> 7x = 28[/tex]
[tex]=> x = \frac{28}{7} = 4[/tex]
∴ DE = 4×4 + 4 = 20 units

Step-by-step explanation:
Name the vertex of each angle the same as the angle letter. Name the intersection of the "horizontal" and "vertical lines" point Q.
Angle ZXQ is vertical to ∠x, so is the same measure.
Angle YQX is the value that makes the sum of angles in triangle XYQ be 180°. That is ...
∠YQX = 180° -51° -57° = 72°
This is also the measure of its vertical angle in the other triangle. Angle z is the sum of that vertical angle and 60°, so we have ...

20. Find the mean, median, and mode for the following
data set:
83 98 22 89 99 98
Answers
Answer:
a. Mean = 81.5
b. Median = 93.5
c. Mode = 98
Step-by-step explanation:
Given the following data;
x = 83, 98, 22, 89, 99, 98
F(x) = 83 + 98 + 22 + 89 + 99 + 98
F(x) = 489
Number of items, n = 6
a. To find the mean;
Mean = F(x)/n
Mean = 489/6
Mean = 81.5
b. To find the median;
Median refers to the middle number of a sorted data. Thus, we would arrange the number in an ascending order and choose the middle number.
x = 22, 83, 89, 98, 98, 99
Middle numbers = 89 and 98
Median = (89 + 98)/2
Median = 187/2
Median = 93.5
c. To find the mode;
Mode is the number which appeared the most in the series.
Mode = 98
The Mean, median, and mode for the following data set are as follows:
Mean is 81.5Median is 93.5Mode is 98.What are the measures of central tendency?The measures of central tendency include the mode, the median, and the mean.
Statistically, a central tendency is a typical value for a probability distribution.
The mode's value appears most often in a set of data values. The median is the middle value of a dataset. The mean represents the average.
Data and Calculations:Data set (in ascending order)
22 + 83 + 89 + 98 + 98 + 99 = 489
Mean = 81.5 (489/6)
Median = 93.5 (89 + 98)
Mode = 98 (occurred twice more than other values)
