Step-by-step explanation:
Area of Triangle: b*h*1/2
The isosceles triangle's height, splits the base in half.
Answer:
672
Step-by-step explanation:
Area of a triangle = [tex]\frac{bh}{2}[/tex]
where b = base length and h = height
In the triangle shown, we are only given the base length
This means that we must find the height in order to find the area.
We can do this by using the Pythagorean theorem
[tex]a^2+b^2=c^2[/tex]
where a and b = legs and c = hypotenuse
Two right triangles are formed within the isosceles triangle.
Each has a hypotenuse of 50 m, a base length of 28/2=14m ( because they are sharing the base length ) and they are both sharing the height.
So we are given the hypotenuse and a leg and we need to find the other leg
So we plug in what we are given and solve for the missing side length
[tex]50^2=a^2+14^2\\50^2=2500\\14^2=196\\2500=a^2+196[/tex]
step 1 subtract 196 from each side
2500 - 196 = 2304
196 - 196 cancels out
we now have 2304 = a²
step 2 take the square root of each side
[tex]\sqrt{a^2} =a\\\sqrt{2304} =48[/tex]
we're left with a = 48
This means that the height of the isosceles triangle is 48m
Now we can find the area.
Using the formula stated previous....
[tex]A=\frac{28*48}{2} \\28*48=1344\\\frac{1344}{2} =672[/tex]
Hence, the area is 672m²

probability that the person will not die in the next year?
A. 0.902%
B. 99.098%
C. 0.098%
D. 99.902%
Answers
Answer:
B. 99.098%
Step-by-step explanation:
The probability that the person will not die in the next year is 99.098% .
Correct option is B.
What is probability?Measure of the likelihood of an event happening is called Probability. Probability can be between 0 to 1. 0 means the event cannot happen, 1 indicates the specific event. The sum of the probabilities of all events in the sample space is 1.
Probability can be defined as the ratio between the number of favorable outcomes and the total number of outcomes of an event. For a trial with “n” number of results, the number of favorable outcomes can be denoted by x. The formula for calculating the probability of an event is as follows.
Probability (Event) = Favorable Outcome/Total Outcome = x/n
Given,
Probability of a person will die next year = 902/100000
sum of the probabilities of all events in the sample space is 1.
Then probability of the person will not die in the next year
= 1 - 902/100000
= 1 - 0.00902
= 0.99098
= 0.99098 × 100/100
= 99.098%
Hence, 99.098% is the probability that the person will not die in the next year.

Which expressions correctly represent the area of the triangle XYZ?
Answers
Answer:
Options (2) and Option (1)
Step-by-step explanation:
Area of the ΔXYZ = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(XZ)h[/tex]
= [tex]\frac{1}{2}(18)h[/tex]
By applying sine rule in the ΔYPZ,
sin(38°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(38°) = [tex]\frac{h}{14}[/tex]
h = 14[sin(38°)]
Therefore, area of the given triangle = [tex]\frac{1}{2}(18)(14)sin(38)[/tex]
By applying sine rule in ΔYPZ,
sin(58°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(58°) = [tex]\frac{h}{10}[/tex]
h = 10sin(58°)
Area of ΔXYZ = [tex]\frac{1}{2}(18)(10)sin(58)[/tex]
Therefore, Options (2) and Option (1) are the correct options.

The maintenance department at the main campus of a large state university receives daily requests to replace fluorescent light bulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 43 and a standard deviation of 11. Using the 68-95-99.7 rule, what is the approximate percentage of lightbulb replacement requests numbering between 10 and 43
Answers
Answer:
The approximate percentage of lightbulb replacement requests numbering between 10 and 43 is of 49.85%.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 43
Standard deviation = 11
The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are above the mean.
What is the approximate percentage of lightbulb replacement requests numbering between 10 and 43?
43 is the mean
10 = 43 - 3*11
So 10 is 3 standard deviations below the mean.
Of the 50% of measures below the mean, 99.7% are between 3 standard deviations below the mean(10) and the mean(43). So
0.5*0.997 = 0.4985.
0.4985*100% = 49.85%.
The approximate percentage of lightbulb replacement requests numbering between 10 and 43 is of 49.85%.
On a standardized test, the mean is 37 and the standard deviation is 2.5. Approximately what percent of the scores fall in the range 32 - 42 ?
A) 68%
B) 95%
C) 34%
D) 99%
Answers
Answer:
B) 95%
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 37, standard deviation = 2.5
Approximately what percent of the scores fall in the range 32 - 42 ?
32 = 37 - 2*2.5
So 2 standard deviations below the mean
42 = 37 + 2*2.5
So 2 standard deviations above the mean.
This question is the percentage of scores within 2 standard deviations of the mean, so, by the Empirical Rule, it is 95%, option B.
