Answer:
11.3 (√128)
Step-by-step explanation:
[tex] \\ {a}^{2} + {b}^{2} = {c}^{2} [/tex]
in this case a is given and c is given
a =side of the triangle
b= side of the triangle
c = hypotenuse or the longest side of the triangle
4^2 + b^2 = 12^2
16+ b^2 = 144
144 - 16 = b^2
128 = b^2
√128 = b
11.3137...= b = 11.3 (rounded to nearest tenth)

A cannon ball has been catapulted through the air and follows the path created by the
function f(t) = -16t2 + 30t + 7 where f(t) is the height of the cannon ball in
meters at any given time (t) in seconds.
Answers
Answer:
the cannon ball's maximum height is 21 meters rounded to the nearest whole number
Step-by-step explanation:
The maximum height of the cannonball will be 21.06 meters when the time t = 0.9375 seconds.
What is the parabola?It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.
A cannonball has been catapulted through the air and follows the path created by the function given below.
f(t) = -16t² + 30t + 7
where f(t) is the height of the cannonball in meters at any given time (t) in seconds.
Then the height of the cannonball will be given by the differentiation. Then we have
[tex]\rm \dfrac{d}{dx} f(t) = -16t^2 + 30 t + 7 \\\\\\\dfrac{d}{dx} f(t) = -32t + 30[/tex]
Then again differentiate to check whether the value is maximum or minimum.
[tex]\rm \dfrac{d^2}{dx^2} f(t) = -32t + 30\\\\\\\dfrac{d^2}{dx^2} f(t) = -32\\\\\\\dfrac{d^2}{dx^2} f(t) < 0[/tex]
Then the value of the height will be maximum for f'(t) = 0.
f'(t) = 0
-32t + 30 = 0
t = 30/32
t = 0.9375
Then the maximum height will be
f(t) = -16(0.9375)² + 30(0.9375) + 7
f(t) = -14.0625 + 28.125 + 7
f(t) = 21.0625
f(t) = 21.06 meters

Step-by-step explanation:
The change in y between x=-1 and x=2 is -3 and -3/3=-1 so the slope is -1
Answer:
-1
Step-by-step explanation:
Use any 2 points on the line.

slope = (difference in y)/(difference in x)
slope = (-6 - 2)/(10 - 2)
slope = -8/8

At school, 588 students bought a school
shirt, and 147 students did not. What
percent of the students bought a school
shirt?
Answers
Answer:
80%
Step-by-step explanation:
Step 1: Add the given data
588 + 147 = 735
Step 2: Divide the number of students who bought a school shirt by the total number of students
588 ÷ 735
= [tex]\frac{735}{588}[/tex]
= 0.8
Step 3: Convert the decimal to fraction
0.8 = 80% (Move the zero 1 place behind the number and remove the ".")
Or
0.8 × 100 = 80%
Therefore, 80% of students bought a school shirt.

A basketball player makes a free throw 82.6% of the time. The player attempts 5 free throws. Use a histogram of the binomial distribution to determine what is the most likely outcome.
Answers
Answer:
The most likely outcome is exactly 4 free throws
Step-by-step explanation:
Given
[tex]n = 5[/tex] --- attempts
[tex]p = 82.6\%[/tex] ---- probability of a successful free throw
[tex]p = 0.826[/tex]
Required
A histogram to show the most likely outcome
From the question, we understand that the distribution is binomial.
This is represented as:
[tex]P(X = x) = ^nC_x * p^x * (1 - p)^{n-x}[/tex]
For x = 0 to 5, where x represents the number of free throws; we have:
[tex]P(X = x) = ^nC_x * p^x * (1 - p)^{n-x}[/tex]
[tex]P(X = 0) = ^5C_0 * 0.826^0 * (1 - 0.826)^{5-0}[/tex]
[tex]P(X = 0) = ^5C_0 * 0.826^0 * (0.174)^{5}[/tex]
[tex]P(X = 0) = 1 * 1 * 0.000159 \approx 0.0002[/tex]
[tex]P(X = 1) = ^5C_1 * 0.826^1 * (1 - 0.826)^{5-1}[/tex]
[tex]P(X = 1) = ^5C_1 * 0.826^1 * (0.174)^4[/tex]
[tex]P(X = 1) = 5 * 0.826 * 0.000917 \approx 0.0038[/tex]
[tex]P(X = 2) = ^5C_2 * 0.826^2 * (1 - 0.826)^{5-2}[/tex]
[tex]P(X = 2) = ^5C_2 * 0.826^2 * (0.174)^{3}[/tex]
[tex]P(X = 2) = 10 * 0.682 * 0.005268 \approx 0.0359[/tex]
[tex]P(X = 3) = ^5C_3 * 0.826^3 * (1 - 0.826)^{5-3}[/tex]
[tex]P(X = 3) = ^5C_3 * 0.826^3 * (0.174)^2[/tex]
[tex]P(X = 3) = 10 * 0.5636 * 0.030276 \approx 0.1706[/tex]
[tex]P(X = 4) = ^5C_4 * 0.826^4 * (1 - 0.826)^{5-4}[/tex]
[tex]P(X = 4) = 5 * 0.826^4 * (0.174)^1[/tex]
[tex]P(X = 4) = 5 * 0.4655 * 0.174 \approx 0.4050[/tex]
[tex]P(X = 5) = ^5C_5 * 0.826^5 * (1 - 0.826)^{5-5}\\[/tex]
[tex]P(X = 5) = ^5C_5 * 0.826^5 * (0.174)^0[/tex]
[tex]P(X = 5) = 1 * 0.3845 * 1 \approx 0.3845[/tex]
From the above computations, we have:
[tex]P(X = 0) \approx 0.0002[/tex]
[tex]P(X = 1) \approx 0.0038[/tex]
[tex]P(X = 2) \approx 0.0359[/tex]
[tex]P(X = 3) \approx 0.1706[/tex]
[tex]P(X = 4) \approx 0.4050[/tex]
[tex]P(X = 5) \approx 0.3845[/tex]
See attachment for histogram
From the histogram, we can see that the most likely outcome is at: x = 4
Because it has the longest vertical bar (0.4050 or 40.5%)

How many multisets of three positive integers have a mean of 9, a median of 11 and no mode? A multiset allows multiple instances for each of its elements. For example {1,2,2} and {2,1,2} are the same multiset.
Reminders:
• The Mean is equivalent to the average.
• The Median is the middle value when values are sorted by size.
• The Mode is the most often occurring value and is not set if no value is repeated.
