Solve the inverse steps needed to isolate the variable 24=-12(x+5)
Answer:
X=7
Step-by-step explanation:
24=-12x-60
84=12x
x=7
Answer:
24 = -12x - 60
84= -12x
-7 = x
Find the length of the third side. If necessary, round to the nearest tenth.
12
=========================================================
Work Shown:
a = 9, b = 12 are the two legs of the right triangle
c = unknown is the hypotenuse
Apply the pythagorean theorem to find c
a^2 + b^2 = c^2
9^2 + 12^2 = c^2
81 + 144 = c^2
225 = c^2
c^2 = 225
c = sqrt(225)
c = 15
Answer:
15
Step-by-step explanation:
Since this is a right angled triangle we can use pythagoras theorem to work out the length of the hypotenuse, or the the longest side.
pythagoras theorem says that a²+b²=c² with c² being the hypotenuse, or missing side here.
12²+9²=225
Because 225 is equal to C², or C squared, we must take the square root in order to find the actual length.
√225 = 15

15
Answer:
x ≈ 62°
Step-by-step explanation:
By applying tangent rule in the given right angled triangle,
tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(x) = [tex]\frac{15}{8}[/tex]
tan(x) = 1.875
x = [tex]\text{tan}^{-1}(1.875)[/tex]

Question
The lengths, in inches, of adult corn snakes have an unknown distribution with mean 51 and standard deviation 9 inches. A
sample, with size n = 43, is randomly drawn from the population and the mean is taken. What is the probability that the
mean is less than 50.2 inches?
Answer:
0.281 = 28.1% probability that the mean is less than 50.2 inches.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean 51 and standard deviation 9 inches.
This means that [tex]\mu = 51, \sigma = 9[/tex]
A sample, with size n = 43
By the Central Limit Theorem, [tex]s = \frac{9}{\sqrt{43}} = 1.3725[/tex]
What is the probability that the mean is less than 50.2 inches?
This is the pvalue of Z when X = 50.2. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{50.2 - 51}{1.3725}[/tex]
[tex]Z = -0.58[/tex]
[tex]Z = -0.58[/tex] has a pvalue of 0.281
0.281 = 28.1% probability that the mean is less than 50.2 inches.

Answer:
65 pi, the closest one is 204.1 in^2
Step-by-step explanation:
This question is asking a surface area for a cylindrical bowl with top is empty, so you need to find one circle base and one rectangular side, as the hight is 4in, and wide is 10 inch, use the wide to find the circumference of the rectangular side, which is C = pi*d = 10 pi. Then the area for the rectangular side is A = 40 pi, and the area for the circle is A = pi*r^2 = (10/2)^2 * pi = 25 pi. Then add them together get Total area = 40 pi + 25pi = 65 pi or 65 * 3.14 = 204.1 in^2

Step-by-step explanation:

Answer:
6.32
Step-by-step explanation:
I counted up from G to H and I got 6. Since the line is a diagonal it makes it odd as in a weird number like a decimal most times. It can't be 6 because the line wouldn't make it to H it would be just short. 5.83 is already too short. 8 is to long for the line to be as it is now as a diagonal. 8, you would have to count up 6 and 2 to the right perfect but the line doesn't do that.
Sylvie needs $110 for a concert ticket. She already has $16 and she can earn the rest by working 10 hours at her job. If h represents her hourly earnings, which of the following equations can be solved to find Sylvie’s hourly earnings? Select all that apply.
A. 110 – 16 = 10h
B. 110 = 16h + 10
C. 16 = 110 – h
D. 110 = 16 + 10h
E. 110 + 16 = 10h
Answer:
A and D
Step-by-step explanation:
110 = 16 + 10h
Isolate the variable by subtracting 16 from both sides
110 - 16 = 10h
94 = 10h
Divide it by 10 to get the amount for 1 h
9.4 = h
Then plug that in to each equation to check to see which ones are true.

Answer:
[tex]y = 6\\\\x = 6\sqrt{2}\\x=8.485[/tex]
Step-by-step explanation:
The base-angles converse theorem states that in a triangle where two angles are congruent, the sides opposite the congruent angles are congruent. One can apply this theorem to the given triangle, and thus, y = 6, because of the base angles converse theorem.
It is also given that the given triangle is a right triangle, therefore, the isosceles triangle with a right angle theorem is applicable. This theorem states that in a right triangle (a triangle with a right angle), that is isosceles (two sides are congruent), the third side (non-congruent side) is equal to the length of the two congruent sides times the square root of (2). Hence, x = [tex]6\sqrt{2}[/tex], in the decimal form that is 8.485.

However, the cooperation rate (probability of someone at the contacted household agreeing to be interviewed) was 43% in 1997 and dropped to 14% in 2012. (a) What is the probability (in 2012) of obtaining an interview with the next household on the sample list
Answer:
14% probability of obtaining an interview with the next household on the sample list
Step-by-step explanation:
Cooperation rate of 14%
This means that the probability of someone at the contacted household agreeing to be interviewed is 14%, and the probability of a person agreeing to be interviewed in a household is independent of what happened in other households, that is, for each household, there is a 14% probability of obtaining an interview.
14% probability of obtaining an interview with the next household on the sample list
