The mean of the discrete probability distribution is of 1.28.

The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.

Then, considering the given distribution, the mean is given by:

E(X) = 0(0.13) + 1(0.61) + 2(0.15) + 3(0.07) + 4(0.04) = 1.28.

Answer: D. Trapezoid

Step-by-step explanation:

From the question, it tells us that each angle was congruent to its opposite angle, since in a rectangle all angles are 90 degrees, rectangles won’t be correct. Parallelograms is self explanatory. Rhombuses have 2 pairs of same angles, which only leads to a trapezoid with 2 different bases, leading to different angles in it’s opposite corner.

Some 679 admissions were appropriate, some 260 were inappropriate, and some 193 were unnecessary.

Given that a New England Journal of Medicine study found that a substantial portion of acute hospital care is reported to be unnecessary, and the physicians who conducted the study reviewed the medical records of 1,132 patients hospitalized at six different locations across the country, and overall, 60% of admissions in the sample were judged to be appropriate, 23% were deemed inappropriate, whereas 17% could have been avoided by the use of ambulatory surgery, to determine the number of patients in each group, the following calculation should be made:

Thus, some 679 admissions were appropriate, some 260 were inappropriate, and some 193 were unnecessary.

Answer:

442.96875 ft.

Step-by-step explanation:

Original Height (h) : 150 ft

Bounce 1 (h₁) : h/2 = 150/2 = 75 ft

Bounce 2 (h₂) : h₁/2 = 75/2 = 37.5 ft

Bounce 3 (h₃) : h₂/2 = 37.5/2 = 18.75 ft

Bounce 4 (h₄) : h₃/2 = 18.75/2 = 9.375 ft

Bounce 5 (h₅) : h₄/2 = 9.375/2 = 4.6875 ft

Bounce 6 (h₆) : h₅/2 = 4.6875/2 = 2.34375 ft

Finding the sum of bounces 1 - 5 :

Distance traveled :

Answer:

442.96875 ft

Step-by-step explanation:

We can model the height of each bounce as a geometric series.

General form of a geometric sequence: [tex]a_n=ar^{n-1}[/tex]

(where [tex]a[/tex] is the initial term and [tex]r[/tex] is the common ratio)

If we let n be the number of bounces, then the initial term has to be:

[tex]a_1=\dfrac12(150)=75[/tex]

since this is the height of the ball after the first bounce.

The common ratio r has already been given to us, as we have been told that the height of the bounce halves after each bounce.

[tex]\implies r=\dfrac12=0.5[/tex]

Therefore, the geometric series to model the peak height of each bounce is:

[tex]a_n=75(0.5)^{n-1}[/tex]

(where [tex]a_n[/tex] is the height and n is the number of bounces)

Therefore, to calculate the total number of feet the ball travels until it reaches the peak height of the 6th bounce:

Total = 150 + (2 × sum of 1, 2, 3, 4 & 5th bounces) + 6th bounce

To find the sum, use the geometric sum formula:

[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]

Therefore, the sum of the bounces 1 through 5 is:

[tex]\implies S_5=\dfrac{75(1-0.5^5)}{1-0.5}=145.3125[/tex]

Height of the 6th bounce:

[tex]\implies a_6=75(0.5)^{6-1}=2.34375[/tex]

[tex]\begin{aligned}\textsf{Total distance} & =150+2\left(\dfrac{75(1-0.5^5)}{1-0.5}\right)+75(0.5)^{6-1}\\ & = 150 + 2(145.3125)+2.34375\\ & = 150 + 290.625+2.34375\\ & =442.96875\: \sf ft \end{aligned}[/tex]

Based on the number of times Johnny performs the experiment, the order from the largest difference in relative frequency and actual prob. to the smallest is:

The difference between absolute probability and relative frequency will be larger if the number of experiments performed is smaller.

This is why the largest difference was seen when Johnny performed the experiment 20 times and the smallest difference was seen when the experiment was done 75 times.

Answer:

Option D. all real numbers.

Step-by-step explanation:

The given function is a logarithmic function represented as

f(x) = log0.6x

In this logarithmic function for any value of x > 0 will be the domain and range of the function will be a set all real numbers.

As for any value of x>0 we get a real number if we rewrite a function in the form of an equation

y = log0.6x

Therefore Range will be (-∞ ∞) {y | y ∈ R}

Answer:

72 in²

Step-by-step explanation:

since the trap is open left and right, we don't include these side areas.

so, all we have for the surface area are

the top rectangle (2.5 in × 12 in),

the bottom rectangle (2 in × 12 in)

the back rectangle (1.5 in × 12 in)

for the total surface area we need to to add all 3 areas up.

in our case we get

2.5 × 12 = 30 in²

2 × 12 = 24 in²

1.5 × 12 = 18 in²

total is then

30 + 24 + 18 = 72 in²

Answer: The larger angle (Angle 2) is 120 degrees

Step-by-step explanation:

Let's call Angle 1 x and call Angle 2 y.

Two angles being supplementary means that they add to 180.

This means x+y=180

Angle 2 is twice the measurement of angle 1.

This means 2x=y and that we can sub 2x in for y

x+2x=180

3x=180

Now solve for x

[tex]3x=180\\\frac{3x}{3} =\frac{180}{3} \\x=60[/tex]

We know the value of x, so now let's sub in to find the value of y

[tex]2x=y\\2(60)=y\\120=y[/tex]

Answer:

140 minutes

Step-by-step explanation:

14 minutes+14 minutes=28 minutes, 28 minutes x 5 days= 140 minutes

The two angles sum to equal 180 degrees.

4x + 8x = 180

12x = 180

X = 180/12

X = 15

Answer:

Soln:4x°+8x°=180°

12x°=180°

or,x°=180°/12

or,x°=15

4x°=4×15°=60°

8x°=8×15°=120

Answer:

x=74

Step-by-step explanation:

because those two angles you can assume are equal, and all you have to do is subtract 180 by 32 and divide 148 by 2 to get the other two parts of the triangle.
