Answer:
x = 9.9 or 10
Step-by-step explanation:
to find missing angle -->
90 + 61 + z = 180
151 + z = 180 *subtract 151 from both sides*
z = 29
to find x -->
tan (29) = x/18 *put tan(29) over 1 then cross multiply*
x = 18 (tan(29))
x = 9.97 --> round up to 10

Answer:
1 3/35
Step-by-step explanation:
4/5 +2/7
To solve this you need to find the common denominator.
Basically, you want to find a number that both 5 and 7 multiply into.
In this case, it is 35.
So we wanna make both fraction's denominators (the bottom numbers) into 35.
The only way we can do this is by multiplying the left fraction 4/5 by 7/7 and the right fraction 2/7 by 5/5.
In the end you get 28/35 +10/35. Now you can add them and you get 38/35 which simplifies to 1 3/35.
- 17x2 - 30x = 40 What is b + c?
Answers
9514 1404 393
Answer:
+70 or -70, depending on how you rewrite the equation
Step-by-step explanation:
A quadratic equation in standard form can be written as ...
ax² +bx +c = 0
When this equation is written in standard form, it could be either of ...
17x² +30x +40 = 0 . . . . . . . . . . add 17x²+30x to both sides
or
-17x^2 -30x -40 = 0 . . . . . . . . . subtract 40 from both sides
__
In the first case, a = 17, b = 30, c = 40 and (b+c) = 70.
In the second case, a = -17, b = -17, c = -40 and (b+c) = -70.
_____
Additional comment
I personally prefer a positive leading coefficient, but it is less work to subtract 40 from both sides than to subtract 2 terms from both sides. Check your curriculum materials for the preferred rewrite in this case.

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.

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 !!!

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.

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
