Answer:
40 units
Step-by-step explanation:
The slanted side is the hypotenuse of a triangle that is 8 units high and 6 units wide. Its length can be found from the Pythagorean theorem:
d² = 6² + 8² = 100
d = √100 = 10
The perimeter is the sum of side lengths. Those lengths can be found by counting grid squares. Clockwise from the upper left corner, the sum of side lengths is ...
P = 8 + 10 + 14 + 8
P = 40 . . . units

Dr. Nunez wants to estimate the average lung capacity of adults in her state. She plans on taking a sample
of n adults to construct a 99% confidence interval for the mean lung capacity. She wants the margin of
error to be no more than 100 mL. She's willing to use o = 300 mL as an estimate for the population
standard deviation.
Which of these is the smallest approximate sample size required to obtain the desired margin of error?

The solution is :
0.8152 ≤ p ≤ 0.8608
579 sample size is needed to be 95% confident that the error in estimating the true value of p is less than 0.03.
What is the confidence interval?A confidence interval is a range of values, derived from a sample of data, that is likely to contain an unknown population parameter with a certain level of confidence.
here, we have,
Given the following :
Samples size n = 1000
Deaths within 10 years, p = 838
α = 95%
Construction a two way confidence interval:
p ± Zα/2 * √p(1-p) / n
point estimate p = 838/n = 838/1000 = 0.838
Z0.05/2 = Z0.025 = 1.96
0.838 - 1.96√0.838(1-0.838) / 1000
0.838 - 1.96*0.0116514 = 0.8152
0.838 + 1.96√0.838(1-0.838) / 1000
0.838 + 1.96*0.0116514 = 0.8608
0.8152 ≤ p ≤ 0.8608
b) Using the point estimate of p obtained from the preliminary sample, what sample size is needed to be 95% confident that the error in estimating the true value of p is less than 0.03
Error (E) = 0.03
To find the samome size, use the relation:
n = (Zα/2 / E)² * p(1-p)
n = (1.96/0.03)² * 0.838(1-0.838)
n = (1.96/0.03)² * 0.838 * 0.162
n = 4268.4444 * 0.838 * 0.162
n = 579.46
n = 579
Hence, The solution is :
0.8152 ≤ p ≤ 0.8608
579 sample size is needed to be 95% confident that the error in estimating the true value of p is less than 0.03.

I don't know if you meant to say hundredth but in this case you said hundred and I can't just make assumptions.
The answer is
- - - - -
0
Like literally, I am not stealing your points but you said to the nearest hundred. So in this case, it'd be 0.
21.25!
The hundredths place is the second number to the right of the decimal, you will look at the thousandths place (3rd number to the right) and if it is less than 5 you will keep the hundredths the same, if it is above 5 you will round the number up.
In this case, your thousandths spot is less then 5, therefore the answer is 21.25 !!!

Two sides of a triangle have measures 3 ft. and 6 ft. Also, these sides form a vertex whose angle measures 60 degrees. Calculate the missing attributes of the triangle. Statements: x² + 3² = 6², where x is the 3rd side of the triangle. x² = 3² +6² + 2⋅3⋅6⋅cos 60°, where x is the 3rd side of the triangle. x² = 3² + 6² − 2⋅3⋅6⋅cos60°, where x is the 3rd side of the triangle. (sin 60°)/3 = (sinθ)/6, where θ is an unknown angle.
Answers
Answer:
c² = 3² +6² - 2⋅3⋅6⋅cos 60
c = 27ft
Step-by-step explanation:
Since the angle is located in between the sides of the sides, we will use the cosine rule to get the unknown sides
Let c be the missing sides
According to the cosine rule;
c² = a²+ b² - 2abcosC
c² = 3² +6² - 2⋅3⋅6⋅cos 60
c² = 9 + 36 - 36cos60
c² = 45 - 36cos60
c² = 45 - 36(0.5)
c² = 45 - 18
c² = 27ft
Hence the missing attribute is 27ft and the required expression is c² = 3² +6² - 2⋅3⋅6⋅cos 60

Answers
Answer:
1) Statistic
2) Parameter
3) Statistic
4) Parameter.
Step-by-step explanation:
Parameter: is a number that describes the whole population.
Statistic: is a number that describes a sample.
The difference is:
50% of the cats are nice (parameter, because talks about all the cats)
out of 100 cats surveyed, 39 are nice (statistic, because talks about a sample of 100 cats)
Then:
1) 85% of those surveyed were in favor of bike lanes.
This only refers to the surveyed people, so this only refers to a sample (and not the population that this sample represents) then this is a statistic statement.
2) Each member of the soccer team has an average of 2 jerseys.
In this case, we are talking about the whole population (the soccer team) then this is a parameter
3) Of the 100 swim teams surveyed across America, 23 practice 10 hours a week.
Here the information is about the sample (only 100 swim teams). So here the correct option is statistic.
4) The golf team's average score is 79
Here the information is about the average score for the entire golf team, so this information is about all the population in the golf team, then in this case the correct option is parameter.

the sum of two numbers is 52. If one number is 76 times the second number, then find the largest number out of the two.
Answers
Answer:
The larger number is 51.3. (to 3 s.f.)
Step-by-step explanation:
Let the smaller number be x and the larger number be y.
Given that the sum of the 2 numbers is 52,
x +y= 52 -----(1)
One number is 76 times the second number. Since we have made y to be the larger number,
y= 76x -----(2)
Substitute equation (2) into (1):
x +76x= 52
Simplify:
77x= 52
Divide both sides by 77:
x= 52 ÷77
[tex]x = \frac{52}{77} [/tex]
x= 0.675 (3 s.f.)
Substitute the value of x into (2):
[tex]y = 76( \frac{52}{77} )[/tex]
[tex]y = 51 \frac{25}{77} [/tex]
y= 51.3 (3 s.f.)
