Answer:
19/30
Step-by-step explanation:
30 students
12 have cat , 19 have dog , 6 no cat or dog
P dog = 19 have dogs/30 students total = .633333...
The likelihood that a randomly selected student in the class owns a dog is 19/30.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
Let A be the event that a student has a dog. Then, the number of students having a dog is 19, and the total number of students is 30.
The number of students having neither a cat nor a dog is 6. Therefore, the number of students having at least a cat or a dog is:
12 (number of students having a cat) + 19 (number of students having a dog) - 6 (number of students having neither a cat nor a dog) = 25
Thus, P(A) = number of students having a dog / total number of students = 19/30.
Therefore, the probability that a student chosen randomly from the class has a dog is 19/30.

The table shows the balance of Kelly’s bank account at the beginning of each month.
The lowest balance Kelly had the beginning of any month was $ ______. The highest balance she had at the beginning of any month was $ ______
The lowest value is a negative number that is furthest away from zero and the highest balance is a positive number which would be the furstest away from zero.
January has the only negative value, so the lowest balance is -45 which was January 2014.
The highest is the largest positive value which is 150 which was February 2014

Which group of three squares will form a right triangle when
joined at their vertices?
Answer:
Option ?) 17 cm, 15 cm, 8 cm
The assignment should have four options to choose from, but there is only a picture of two.
Step-by-step explanation:
None of the squares shown form a right triangle. To determine if sides form a right triangle, you use this formula:
a²+b²=c²
We are given two options in the picture.
Option A) 18, 10, and 8.
Option B) 12, 9, and 6.
So, now we need to apply the formula:
Option A)
║8² + 10² = 18²
↓
║64 + 100 = 324
↓
║FALSE
Option B)
║6² + 9² = 12²
↓
║36 + 81 = 144
↓
║FALSE
Both of these options are false. But, I decided to look up this assignment to check my answer. It turns out, there are 4 options, and you only had a picture of two. So, what's the answer?
There is an answer choice that shows 3 squares with the lengths of 17 cm, 15 cm, and 8 cm. This is the correct answer.
For proof, let's apply the formula:
Option ?)
║8² + 15² = 17²
↓
║64 + 225 = 289
↓
║TRUE
[Since the option isn't shown, I'll put a '?' so there is no confusion]

How do you find zeros of a quadratic function?
Answer:
You find the zeros of a quadratic functions by factoring the function. And once you have factored the function you take the factors and flip the signs. For example, you have the factors (x-4) and (x+3).
Drop the parentheses and make x equal to zero.
x - 4 = 0 x - 3 = 0
Solve it like a one step equation.
x - 4 = 0 x - 3 = 0
+ 4 +4 +3 +3
= 4 = 3
Then turn into coordinates.
x y x y
(4,0) (3,0)
Note that the zero's are the x-intercepts. I labeled x above the first part of the coordinate to show where the x-intercepts should and the same with the y.

Answer:
x → +∞, y → +∞
x → -∞, y → -∞
Step-by-step explanation:
The trick to identify its behavior is to determine the degree of the function and the coefficient of the term with the highest exponent.
Negative coefficient and odd degree (x → +∞, y → -∞) (x → -∞, y → +∞).Negative coefficient and even degree (x → +∞, y → -∞) (x → -∞, y → -∞).Positive coefficient and odd degree (x → +∞, y → +∞) (x → -∞, y → -∞).Positive coefficient and even degree (x → +∞, y → +∞) (x → -∞, y → +∞).Which form most quickly reveals the vertex?

At the amusement park, Janine bought a bottle of water for $2. She also bought game tickets for $0.50 each. Janine spent a total of $15.
Which of the following equations can be used to find the number of game tickets, g. Janine bought?
O 0.509 + 2 = 15
O2g +0.50 = 15
O 0.50g - 2 = 15
O 2g -0.50 = 15
Answer:
15 = 2 + 0.5g
Total number of ticket purchase by Janine = 26
Step-by-step explanation:
Given:
Cost of water bottle = $2
Cost of each ticket = $0.50
Total amount spend by Janine = $15
Find:
Equation
Computation:
Assume;
Total number of ticket purchase by Janine = g
Total amount spend by Janine = Cost of water bottle + (Cost of each ticket)(Total number of ticket purchase by Janine)
15 = 2 + (0.5)(g)
15 = 2 + 0.5g
0.5g = 13
g = 13 / 0.5
Total number of ticket purchase by Janine = 26

In \triangle CDF,m\angle D=90\deg,m\angle C=29\deg△CDF,m∠D=90deg,m∠C=29deg and the length of the hypotenuse is 10 units. Using this information below, what is the length of CDCD? 5.5 units 4.8 units 8.7 units 2.9 units
Answer:
8 units
Step-by-step explanation:
Given
Hypotenuse CF = 10
m<C = 29degrees
m<D = 90degrees
m<F = 180 - (29+90)
m<F = 180 - 119
m<F = 61degrees
Since the side facing <F is CD, then;
Opposite = CD
using the SOH CAH TOA identity
sin 61 = opp/hyp
sin61 = CD/10
CD = 10sin61
CD = 10(0.8746)
CD = 8.746
Hence the length of CD is 8 units

Hope this helps!
Answer:
1/x⁴
Step-by-step explanation:
We need to simplify the expression , x -⁴ .
We know that , if a number has negative power, then in order to convert , the negative power into positive , we will inverse ( reciprocal) and then put the positive power.=> x -⁴
=> (1/x) ⁴
=> 1⁴/ x ⁴
=> 1/x⁴
Hence the required answer is 1/x⁴ .pls help me tysmmmm!!!
