Answer:

135 degrees.

Step-by-step explanation:

Assuming that it is a regular octagon, you can use the formula (n-2) (180) divided by n. n = sides. Therefore, (8-2) (180) divided by 8, which is 135.

13 is x

144+25=169

169 is 13 squared

Answer:

Step-by-step explanation:

The two triangles are similar dues to the ASA therom, so we can relate the sides to one another. That means that

13x=11x-4

2x=-4

x=-0.5

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:

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

Answer:

Step-by-step explanation:

I’m assuming you meant to write

T = ⅛x + 9

T = ⅛(20) + 9 = 11.5

The required estimate of tuition for one year at the college in 2020 is $11500

Given,
The tuition T for one year at a college can be approximated by the equation.
                   T = 1/8x + 9  - - - - - - (1)
where x is the year since 2000, and T is tuition in thousands of dollars.
Tuition fee in the year 2020 to be calcuate.

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

The expression is given, since 2000
so the change in years
x = 2020 - 2000
x = 20
Put this x in equation 1
T = 20/8 + 9
T = 2.5 + 9
T = 11.5
SInce t is in thousand so Tuition fee = $11,500.

Thus, the required estimate of tuition for one year at the college in 2020 is $11500

Answer:

45 inches

Step-by-step explanation:

Answer: 45 in

Step-by-step explanation:

1 ft = 12 in

3 ft = 12 * 3 = 36 in

3/4 ft = 9 in

36 + 9 = 45 in

Answer:

$12

Step-by-step explanation:

37.50 / 25 = 1.5

1.5 x 8 = $12

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]

x = 61.93

x ≈ 62°

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.

Answer:

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

Answer:

[tex]Probability = 0.00002619[/tex]

Step-by-step explanation:

Given

Let d represents the event that a radar detects an aircraft.

So:

[tex]P(d) = 0.03[/tex]

Required: Determine the probability that a radar detects three before it fails to detect 1.

This event is represented as: d d d d'

And the probability is calculated as thus:

[tex]Probability = P(d) * P(d) * P(d) * P(d')[/tex]

Using complement rule:

[tex]Probability = P(d) * P(d) * P(d) * (1 - P(d))[/tex]

So, we have:

[tex]Probability = 0.03 * 0.03 * 0.03 * (1 - 0.03)[/tex]

[tex]Probability = 0.03 * 0.03 * 0.03 * 0.97[/tex]

[tex]Probability = 0.00002619[/tex]
