Question 14 of 25
In a group of 40 students, the probability that at most 15 of them like to hike
is 54%. What is the probability that at least 16 of them like to hike?
O A. 38%
B. 46%
C. 55%
D. 62%
The probability that at least 16 of them like to hike would be equal to 46% So, option B is correct.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
In a group of 40 students, the probability that at most 15 of them like to hike is 54%. we need to find the probability that at least 16 of them like to hike.
The probability that at most 15 of them like to hike = 54%
Let the total possibility be 100%
then 100 - 54 = 46%
Therefore, the remaining possibility is the probability for at least 16 of them like to hike.

Which of the following do not represent the measures of the sides of a triangle?
A)57, 80, 24
B) 43, 133, 89
C) 5, 6, 7
D 20, 20, 30
===========================================================
Explanation:
For this answer choice, we have p = 43, q = 133, and r = 89. Note how p+r = 43+89 = 132, which is not larger than the third remaining side q = 133. Therefore, p+r > q is false and a triangle cannot be formed.
A triangle is only possible if and only if adding any two sides leads to a sum larger than the third side (triangle inequality theorem).
Put another way, we must have these three conditions hold true for a triangle to form:
p+q > rp+r > qq+r > pIf any of those three are false, then we cannot make a triangle with side lengths p,q,r
-----------------
Let's go over choice C for an example in which we can form a triangle
p = 5, q = 6, r = 7
We can see that,
p+q = 5+6 = 11 which is greater than r = 7. So p+q > r is true.p+r = 5+7 = 12 which is greater than q = 6. So p+r > q is true.q+r = 6+7 = 13 which is greater than p = 5. So q+r > p is true.All three conditions are true, and therefore we have a triangle that is possible with side lengths p = 5, q = 6, r = 7. I recommend cutting out slips of paper with these lengths to try it out yourself, so you have a real world example to play with. Choices A and D are a similar story to choice C, so we can rule out all three of these choices.

What is the area of the shaded region?
Answer:
42.5 square.cm
Step-by-step explanation:
Find the diagram attached
Area of the shaded portion = area of square - area of circle
Area of square = L²
Area of square = 11 × 11
Area of square = 121 square centimetres
Area of circle = pir²
r is the radius of the circle = 5cm
Area of the circle = 3.14×5²
Area of the circle = 3.14×25
Area of the circle = 78.5 square. cm
Area of the shaded region = 121 - 78.5
Area of the shaded region = 42.5 square.cm

Step-by-step explanation:
Together they spent a mean price of $40 on 8 sweaters. The first 7 sweaters cost $50, $55, $30, $35, $39, $40 and $42. How much, in dollars, does the 8th sweater cost?
If the mean price is $40, 8 x 40 = the total price, = 320
Add up what we knew they spent:
50 + 55 + 30 + 35 + 39 + 40 + 42 = 291
The difference between those 2 numbers is the price of the 8th sweater
320 - 291 = 29

Rate of change for y=1x+1
Answer:
The rate of change is 1
Step-by-step explanation:
The rate of change is the same as the slope, the ratio of the change in y over the change in x. In this case, the slope is 1, making the rate of change also 1.

solve the system of equations x-y=-14 and 5x+7y=-10 by combining the equations.
Answer:
x+y=-4
Step-by-step explanation:
you need to solve this using elimination!
add both equations to each other:
x-y=-14
5x+7y=-10
the answer would be
6x+6y=-24
to go further,
it would be....
x+y=-4
because you can divide both sides by 6

Answer:
[tex]\frac{4}{3}[/tex]
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ - 1, 1 ]
f(b) = f(1) = 3 ← value of y when x = 1
f(a) = f(- 1) = [tex]\frac{1}{3}[/tex] ← value of y when x = - 1
average rate of change = [tex]\frac{3-\frac{1}{3} }{1-(-1)}[/tex] = [tex]\frac{\frac{8}{3} }{2}[/tex] = [tex]\frac{4}{3}[/tex]

The distance from library and the park is 12 miles.
What is trigonometric Ratios?"Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle. It is with respect to any of its acute angles are known as the trigonometric ratios of that particular angle".
For the given situation,
Jaime ride her bike in north = 5 miles
Jaime ride her bike in east = 13 miles
The distance from library and the park be x.
The below diagram shows about the Jaime's riding.
The distance from library and the park can be find by using Pythagoras theorem,
[tex]Hypotenuse^{2} = Perpendicular^{2} + base^{2}[/tex]
On substituting the above values,
⇒ [tex]13^{2} = 5^{2}+x^{2}[/tex]
⇒ [tex]x^{2} =169-25[/tex]
⇒ [tex]x^{2} = 144[/tex]
⇒ [tex]x=\sqrt{144}[/tex]
⇒ [tex]x=12[/tex]

2. 5x + 7x + 3x = 60
What’s the value of x?
Answer:
Step-by-step explanation:
Simplifying
7x = -3x + -60
Reorder the terms:
7x = -60 + -3x
Solving
7x = -60 + -3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3x' to each side of the equation.
7x + 3x = -60 + -3x + 3x
Combine like terms: 7x + 3x = 10x
10x = -60 + -3x + 3x
Combine like terms: -3x + 3x = 0
10x = -60 + 0
10x = -60
Divide each side by '10'.
x = -6
Simplifying
x = -6

Given the function f(x) = 0.65x + 117, what
s the x-value of the zero?
Answer:
x = -180
Step-by-step explanation:
0 = 0.65x + 117
-117 = 65x/100
cross-multiply to solve for 'x':
65x = -11700
x = -11700/65
x = -180

A circular pool has a footpath around the circumference. The equation x2 + y2 = 2,500, with units in feet, models the outside edge of the pool. The equation x2 + y2 = 3,422.25, with units in feet, models the outside edge of the footpath. What is the width of the footpath?
Answer:
8,5 feet
Step-by-step explanation:
The equation of the form
x² + y² = (r)²
Is the equation of the circumference
We have for the pool:
x² + y² = 2500 ⇒ x² + y² = (50)²
And for the outside edge of the footpath
x² + y² = 3422,25 ⇒ x² + y² = (58,5)²
So we obtain the radius of each circumference
For the outside edge of the pool r₁ = 50 feet
For the outside edge of the footpath r₂ = 58,5 feet
Then the width of the footpath is 58,5 - 50 = 8,5 feet

[tex] \displaystyle PW = \underline{ \quad18 \quad}[/tex]
Step-by-step explanation:
by tangent property we acquire:
[tex] \displaystyle 3x - 6 = x + 10[/tex]
add 6 to both sides:
[tex] \displaystyle 3x= x + 16[/tex]
cancel x from both sides:
[tex] \displaystyle 2x= 16[/tex]
divide both sides by 2:
[tex] \displaystyle x= 8[/tex]
so,
[tex] \displaystyle PW = 3x - 6[/tex]
plug in the got value of x:
[tex] \displaystyle PW = 3.8 - 6[/tex]
simplify multiplication:
[tex] \displaystyle PW = 24- 6[/tex]
simplify Substraction:
[tex] \displaystyle PW =18[/tex]
hence, The measure of PW is 18 unit
