In a recent survey of 655 working Americans ages 25-34, the average weekly amount spent on lunch was 43.76 with standard deviation 2.67. The weekly amounts are approximately bell-shaped. (c) Between what two values will approximately 95% of the amounts be?
Answers
Answer:
Between 38.42 and 49.1.
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 of 43.76, standard deviation of 2.67.
Between what two values will approximately 95% of the amounts be?
By the Empirical Rule, within 2 standard deviations of the mean. So
43.76 - 2*2.67 = 38.42
43.76 + 2*2.67 = 49.1
Between 38.42 and 49.1.

Answers
7.- BC = 22
8.- EF= 8
Explanation
I don’t really now how to explain this in English but I’ll try.
Since both triangles are congruent, you just have to take the similar segments. For question 7, BC and EF are similar, so you write it down as a division, then you have to equally to the adjacent segments, in this case will be AB/ DE
BC/EF = AB/DE
Then you only have to multiply them in cross, so it would be
BC*DE = EF*AB
U will have function and now u have to find x (cabin this case represents the length of the BC segment)
x*5 = 10*11
Now u clear the x, and it gonna look like
x= 10*11/5
U solve that and the answer is 22
I’ll attach some images in case u don’t understand
Answer:
7. [tex]BC=22[/tex]
8. [tex]EF=8[/tex]
Step-by-step explanation:
7.
It is given that triangle (ABC) is similar to triangle (DEF). This means that triangle (DEF) is a scaled version of the triangle (ABC). Between these two triangles, there is a ratio. This ratio referred to as the ratio of similitude, is a factor that one multiplies a side of the triangle by, to get the length of the corresponding side in the other triangle. This number can be found by dividing the corresponding sides in the triangle.
As per the given picture, side (AB) corresponds to side (DE). Therefore divide side (AB) by (DE) to find the ratio of similitude,
[tex]\frac{AB}{DE}=\frac{10}{5}=2[/tex]
Multiply side (EF) by the ratio of similitude to find the length of its corresponding side (BC).
[tex]2(EF) = 2(11) = 22[/tex]
[tex]BC=22[/tex]
8.
The triangles (ABC) and (DEF) are similar. One can use the same logic applied to the last problem to solve this problem. For further reference, read the intro written to explain the process used to solve the problem (7).
One can see that sides (AB) and (DE) are corresponding sides, divide (DE) by (AB) to find the ratio of similitude;
[tex]\frac{DE}{AB}=\frac{4}{6}=\frac{2}{3}[/tex]
Now multiply this number by side (BC) to find the length of the corresponding side (EF);
[tex](BC)*\frac{2}{3}=EF\\12*\frac{2}{3}=EF\\8=EF[/tex]

Answer:
yes, yes, no; No
Step-by-step explanation:
We have to assume you have no trouble with single-digit addition and comparison of two numbers.
3+4 > 1 ⇒ 7 > 1 . . . . yes
4+1 > 3 ⇒ 5 > 3 . . . . yes
3+1 > 4 ⇒ 4 > 4 . . . . no
These lengths will not make a triangle because the triangle inequality is not satisfied.

You will notice that we found the result of interest when we added the two smallest numbers (1 and 3) and compared the sum to the largest number (4). This is a shortcut you can use for any "will these make a triangle" question. You don't need to bother comparing larger numbers to smaller ones. You already know they are larger.

Answer:
A. 17.5 miles
Step-by-step explanation:
Your knowledge of triangles tells you the hypotenuse is longer than the long leg of the triangle, and is shorter than than the sum of the two legs. This means the difference between Michael's distance and Leah's distance will be strictly less than 25 miles.
The only answer choice in that range is 17.5 miles.
__
If you want to do the math, you can find Michael's distance to be ...
38 +25 = 63 miles.
Leah's distance will be ...
√(38² +25²) = √2069 ≈ 45.5 miles.
Then Michael's excess distance is ...
63 -45.5 = 17.5 miles

An underwriter is analyzing the heights of his clients. He categorizes 35% as tall, 40% as medium height, and 25% as short. He then randomly picks two clients (from his very large client base). What is the probability that neither is tall and at most one is medium height
Answers
Answer:
0.2625 = 26.25% probability that neither is tall and at most one is medium height.
Step-by-step explanation:
Desired outcomes:
Short - Short
Short - Medium
Medium - Short
Probability of two short:
25% are short, so:
[tex]P(A) = (0.25)^2 = 0.0625[/tex]
Probability of short medium or medium short
25% short, 40% medium. So
[tex]P(B) = 2*0.25*0.4 = 0.2[/tex]
What is the probability that neither is tall and at most one is medium height?
[tex]P = P(A) + P(B) = 0.0625 + 0.2 = 0.2625[/tex]
0.2625 = 26.25% probability that neither is tall and at most one is medium height.

No, because according to theoretically probability most of the sweet pea plants have purple flowers causing that one plant to have the probability purple flowers more than of the white flowers!
Here is teh mathematical way-
total plants = 90
purple flowers = 70
white flowers = 20
higher probability of flower = 70/90

An experiment to investigate the survival time in hours of an electronic component consists of placing the parts in a test cell and running them under elevated temperature conditions. Six samples were tested with the following resulting failure times (in hours): 34, 40, 46, 49, 61, 64. (a)Calculate the sample mean and sample standard deviation of the failure time.
Answers
Answer:
The sample mean of failure time was of 49 hours.
The standard deviation of the failure time was of 11.7 hours.
Step-by-step explanation:
Sample mean:
Sum of all values divided by the number of values. So
[tex]\overline{x} = \frac{34+40+46+49+61+64}{6} = 49[/tex]
The sample mean of failure time was of 49 hours.
Standard deviation:
Square root of the division between the sum of the differences squared betweene each value and the mean, divided by the sample size subtracted by 1. So
[tex]s = \sqrt{\frac{(34-49)^2+(40-49)^2+(46-49)^2+(49-49)^2+(61-49)^2+(64-49)^2}{5}} = 11.7[/tex]
The standard deviation of the failure time was of 11.7 hours.
