Answer:

Step-by-step explanation:

let the radius be r and the slant height be L

then first of all: L^2 = r^2 + 9^2

= r^2 + 81

Surface area = πrL = n

volume = (1/3)πr^2 (9) = 3πr^2 = n

then 3πr^2 = πrL

3r = L , then in L^2 = r^2 + 81

9r^2 = r^2 + 81

8r^2 = 81

r = 9/√8

L^2 = 81/8 + 81 = 729/8

L = √1458/4

cos(baseangle) = (9/√8) / (√1458/4)

= 1/3

angle of base = appr 70.5°

Line AE is NOT parallel to line BD. This is because the intercepts made by the lines and the transversals are not proportional

In the given diagram,

If

[tex]\frac{|AB|}{|ED|} =\frac{|AC|}{|EC|}[/tex]

Then,

Line AE is parallel to line BD

From the given information,

|AB| = x = 9

|ED| = 5

|AC| = 9 + 11 = 20

|EC| =5 + 7 = 12

Thus,

[tex]\frac{9}{20}=\frac{5}{12}[/tex]

20 × 5 = 9 × 12

100 ≠ 108

B. The standard deviation is he square root of variance. The larger the standard deviation the more variation

Answer:

this is quite an easy problem.

Step-by-step explanation:

The problem appears to be asking for the class with the greatest variability of test 1, which merely means that you are looking for the graph that has the most distributed test scores. The graph that shows the largest difference in each test score will be your answer.

Answer:

w x 6

Because W is a variable and we don't know what W so it the equation is gonna be a open sentance

The true statement ae:
Both have the same number of data points.

Both means are between 3 and 4.

Westwood has less variability than Middleton.

A dot plot is made up of dots which represents the frequency of the values in the data set and a numberline.

The total number of data points for both dot plots is 20.

The range of Middleton is : 9 -1 = 8

The range of Westwood is: 6 - 2 = 4

Middleton has more variability than Westwood.

Mean sum of numbers / total numbers

Middleton = (1+ 2+  2 + 2 + 2 +  3 + 3 + 3 + 3 + 3 + 4 + 4 + 4 + 4 +  5 + 5 + 5, 5 + 6 + 9) / 20 = 3.75

Westwood = ( 2 + 2 + 2 + 2 + 3 + 3 + 3 + 3 + 3 + 4 + 4 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 6 + 6) / 20 = 3.85

Answer:

x = -4, 1

Step-by-step explanation:

Since we have a absolute value function here, we can tell there is goning to be multiple values.

First we will find x with the original function since we know |5| = 5.

Given f(x) = 5 = -2x-3,

[tex]2x-3 = 5 \\

-2x-3+3 = 5 + 3 \\

-2x = 8 \\

x = \frac{8}{ - 2} \\ = - 4[/tex]

Now we also know that |-5| = 5 as well (absolute value)

Given |-2x-3| = |-5|,

[tex] - 2x - 3 = - 5 \\ - 2x - 3 + 3 = - 5 + 3\\ - 2x = - 2 \\ x = \frac{ - 2}{ - 2} \\ = 1[/tex]

You can verifiy these 2 values by substituting them into the equation.

f(-4) = |-2(-4)-3|

= |8-3|

= |5|

= 5

f(1) = |-2(1)-3|

= |-2-3|

= |-5|

= 5

A modulus function is defined as a function that gives positive value for either a negative or positive argument. The values of x for given condition are -4 and 1.

A function in the form of f(x) = |x| is known as a modulus function. The graph of a modulus function is symmetric about y-axis.

The function is given as,

f(x) = |-2x-3|

which implies that f(x) = -2x - 3 for x > 0 and  f(x) = -(-2x - 3 )for x < 0

As per the question ,

Substitute the value of f(x) = 5, for both the cases to get the value of x as,

-2x - 3 = 5  and -(-2x - 3 ) = 5

=> x = -4 and x = 1.

Hence, the values of x obtained for the given condition are x =-4 and x = 1.

Using the Poisson distribution, it is found that:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

The parameters are:

The average rate is of 3 no-hitters per season, hence:

[tex]\mu = 3[/tex].

The probability that an entire season elapses with a single no-hitter is P(X = 0), hence:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-3}3^{0}}{(0)!} = 0.0498[/tex]

There is a 0.0498 = 4.98% probability that an entire season elapses with a single no-hitter.

Seasons are independent, hence:

If an entire season elapses without any no-hitters, there is a 0.0498 = 4.98% probability that there are no no-hitters in the following season.

The probability that there are more than 3 no-hitters in a single season is P(X > 3) given as follows:

[tex]P(X > 3) = 1 - P(X \leq 3)[/tex]

In which:

[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)[/tex]

Then:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-3}3^{0}}{(0)!} = 0.0498[/tex]

[tex]P(X = 1) = \frac{e^{-3}3^{1}}{(1)!} = 0.1494[/tex]

[tex]P(X = 2) = \frac{e^{-3}3^{2}}{(2)!} = 0.2240[/tex]

[tex]P(X = 3) = \frac{e^{-3}3^{3}}{(3)!} = 0.2240[/tex]

Then:

[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.0498 + 0.1494 + 0.2240 + 0.2240 = 0.6472[/tex]

[tex]P(X > 3) = 1 - P(X \leq 3) = 1 - 0.6472 = 0.3528[/tex]

There is a 0.3528 = 35.28% probability that there are more than 3 no-hitters in a single season.

Using the normal distribution, we have that:

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation of men's heights are given as follows:

[tex]\mu = 69.3, \sigma = 3.9[/tex].

The proportion of men who meet the height requirement is is the p-value of Z when X = 62 subtracted by the p-value of Z when X = 55, hence:

X = 62:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{62 - 69.3}{3.9}[/tex]

Z = -1.87

Z = -1.87 has a p-value of 0.0307.

X = 55:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{55 - 69.3}{3.9}[/tex]

Z = -3.67

Z = -3.67 has a p-value of 0.0001.

0.0307 - 0.0001 = 0.0306 = 3.06%.

Answer:  Either [tex]w(w-4)[/tex] or [tex]w^2 - 4w[/tex]

==================================================

Explanation:

w = width

w-4 = length since it is 4 less than the width

Multiply the length and width to get the area of the rectangle.

area = length*width

area = [tex](w-4)w[/tex]

area = [tex]w(w-4)[/tex]

area = [tex]w^2-4w[/tex]

In the last step, I used the distributive property.

Either expression mentioned above is valid for the area. If you had to pick only one, I'd go for [tex]w^2-4w[/tex]
