A person who attended the gym is selected at random. .
Find the probability that this person:
b) attended only circuits
(2)
c) attended exactly one class
(2)
d) attended spinning, given that they attended circuits
. (2)
The probability that a person chosen at random attended only circuits is 0.16.
The probability that a person chosen at random attended exactly one class is 0.0288.
The probability that a person chosen at random attended spinning, given that they attended circuits is 0.10
What is the probability?
Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
Probability a person chosen at random attended only circuits = number of people who atended circuits / total number of the people at the gym
16/100 = 0.16
Probability a person chosen at random attended exactly one class = (number of people who atended circuits only / total number of the people at the gym) x (number of people who atended spinning class only / total number of the people at the gym)
16/100 x 18/100 = 0.0288
Probability a person chosen at random attended spinning, given that they attended circuits= 10/100 = 0.10

A bag has 11 blue marbles 23 red marbles if you draw marbles without replacemtn what si the probability that you draw no blue marbel
Answer: 66% or 67% if you round it up
Step-by-step explanation: Add 23 and 11 together: 34
I'm not sure how many marbles you drew so I'll say subtract 1: 33
22/33 =.6 repeating.67 if you round it up or 67%
The probability that you draw no blue marble is 23/11.
What is the probability?Probability is a branch of math that deals with finding out the likelihood of the occurrence of an event.
A bag has 11 blue marbles and 23 red marbles.
Total number of marbles = 11 + 23 = 34
The probability of picking blue marbles is;
[tex]\rm Probability=\dfrac{Blue \ marbles }{Total \ marbles}\\\\Proability = \dfrac{11}{34}[/tex]
The probability that you draw no blue marbel IS;
[tex]\rm Probabilty = 1- Blue \ marable\\\\Probability = 1-\dfrac{11}{34}\\\\Probability=\dfrac{34-11}{11}\\\\Probability =\dfrac{23}{11}[/tex]
Hence, the probability that you draw no blue marble is 23/11.

Which statement about the functions is true?
The y-intercept of g(x) is greater than the y-intercept of f(x).
The y-intercept of f(x) is greater than the y-intercept of g(x).
f(x) and g(x) share an x-intercept.
f(x) and g(x) have the same y-intercept.
The statement about both functions that is true is: B. The y-intercept of f(x) is greater than the y-intercept of g(x).
What is the Y-intercept of a Function?The y-intercept of a function is the output value (y) of the function when the input value (x) is zero. On a graph, it would be the value of y-coordinate of the point where the line cut across the y-axis.
From the table given for function g, the value of y when x is zero is 3. The y-intercept for g(x) is 3.
From the graph given for function f, the value of the point at which the line intercepts the y-axis is 6. Therefore, the y-intercept for f(x) is 6.
Therefore, the statement about both functions that is true is: B. The y-intercept of f(x) is greater than the y-intercept of g(x).

If both zeroes of quadratic polynomial (k+2)x^2-(k-2)x-5 are equal in magnitude but opposite in sign find k
Answer:
k=2
Step-by-step explanation:
[tex](k + 2) {}^{2} - (k - 2)x - 5 = 0[/tex]
If we have two zeroes that are equal in size, but different signs then we have a different of squares,
[tex](a + b)(a - b) = {a}^{2} - b {}^{2} [/tex]

Step-by-step explanation:
#1
In this rule, it is saying that is two of the sides are the same and two of the angles are 45 degrees, then you can find the measurement of the hypotenuse or one of the legs of the triangle
Here, the hypotenuse is equal to what the length of one of the legs are and multiplied by [tex]\sqrt{2}[/tex]
Since the length of one of the legs are 4, multiply that by [tex]\sqrt{2}[/tex] and you will get:
4[tex]\sqrt{2}[/tex]
#2
Same concept, but reverse
The hypotenuse is 11[tex]\sqrt{2}[/tex] and to go back to one of the leg lengths, instead of multiplying, you want to divide.
So:
[tex]\frac{11\sqrt{2} }{\sqrt{2} }[/tex]
Which is equal to:
11
You can also do this by knowing that the legs are the same length and knowing that b=11, and a=b, a is also equal to 11
#3
Same as the previous question
[tex]\frac{5\sqrt{2} }{\sqrt{2} }[/tex]
b = 5
#4
a and b are equal to x, and in this case, x is 8.
So going back to the picture, you can see that you need to multiply this x by [tex]\sqrt{2}[/tex] to get 8[tex]\sqrt{2}[/tex]
#5
You'd have to ask your teacher for this one because it is impossible to have a leg that is longer than the hypotenuse
#6-10

Answer:
$1842.30
Step-by-step explanation:
Calculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 4/100
r = 0.04 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 1,400.00(1 + 0.04/1)^(1)^(7)
A = 1,400.00(1 + 0.04)^(7)

Step-by-step explanation:
Isolate the term of x and y from one side of the equation.
y=-15x-5 and 11x+y=-17First, you have to substitute.
[tex]\sf{y=-15x-5=11x-15x-5=-17}[/tex]
Then, you solve.
[tex]\sf{-4x-5=-17}[/tex]
Add by 5 from both sides.
-4x-5+5=-17+5
Solve.
-17+5=-12
-4x=-12
Divide by -4 from both sides.
-4x/-4=-12/-4
Solve.
-12/-4=3
x=3
y=-15*3-5

You need to mark a fifth teen foot beam into five equal segments .how long is each segment ?
Answer: 3
Step-by-step:
15/5=3
Each segment of a fifteen-foot beam divided into five equal parts is 3 feet long.
Since acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
To find out the length of each segment of a fifteen-foot beam divided into five equal parts, we have to divide the total length of the beam by the number of segments it is being divided into.
We can do this using the division operation as shown below:
15 ÷ 5 = 3
Therefore, we can conclude that each segment of a fifteen-foot beam divided into five equal parts is 3 feet long.

For cold drinks, there are cone-shaped paper cups. They have the same volume as the hot-drink cups and a radius of 5.1 centimeters. What is the height of each paper cup?
Use 3.14 and round your answer to the nearest whole number
The height of each paper cup to the nearest whole number is 15cm
The volume of a cylinder and coneThe formula for calculating the volume of a cylinder is expressed as:
V = πr²h
r is the radius
h is the height
Given that h = 9cm and r = 3.8cm
V = 3.14 * (3.8)² * 9
V = 408cm³
For the cone
V = 1/3πr²h
408 = 1/3 (3.14 * (5.1)² * h)
1224 = 81.6714h
h = 1224/81.6714
h= 15cm
Hence the height of each paper cup to the nearest whole number is 15cm
