Tommy has 15 marbles in his pocket. He has 3 green, 4 white, 6 black, and 2 blue marbles. If he randomly puts his hand in his pocket and
grabs a marble, what is the probability that he will pick a black marble?
Answer:
0.4
Step-by-step explanation:
The formula to calculate number of black marbles isnumber of favourable items by number of favourable items i.e for black marbles it will become
P(B)=number of black marbles divide by total number of marbles
P(B)=6/15
P(B)=0.4 OR 40%
Therefore the probability that Tommy will pick black marble is 0.4 or 40%
Given f(x) = x2 − 4x + 5, find . . . .

Answer:f(x) = 3x2 + 5 and y = 3x2 + 5
Step-by-step explanation:
Answer:
Step-by-step explanation:
f(2) = (2)^2 - 4(2) + 5 = 4 - 8 + 5 = -4 + 5 = 1
f(-6)= (-6)^2 - 4(-6) + 5 = 36 + 24 + 5 = 60 + 5= 65

Answer:
18$
Step-by-step explanation:
If Rylie paid 12$ for two cans, then divide twelve by two then you'll get 6$ so 6$ is one can so multiply six by three and you will get 18$ for three cans.

An airline records data on several variables for each of its flights, model of plane, amount of fuel used, time in flight,
number of passengers, and whether the flight arrived on time. The number and type of variables recorded are
1 categorical, 4 quantitative (1 discrete, 3 continuous)
O 3 categorical, 2 quantitative (1 discrete, 1 continuous)
O 1 categorical, 4 quantitative (2 discrete, 2 continuous)
2 categorical, 3 quantitative (1 discrete, 2 continuous)
O 2 categorical, 3 quantitative (2 discrete, 1 continuous)
Answer:
The correct option is;
2 categorical, 3 quantitative (1 discrete, 2 continuous)
Step-by-step explanation:
A categorical variable which is otherwise known as a nominal variable is one which can be qualified as belonging to one class or category of objects or the other, depending on its attributes, and not based on order of the classes.
Therefore;
1) The model of the plane, and 2) whether the flight arrived on time, are categorical variable
A quantitative variable is a variable that indicates measurement and therefore, indicates the numerical magnitude of a measurement.
Therefore;
1) Amount of fuel used, 2) Time in flight, 3) The number of passengers are quantitative variables
Quantitative variables can be either discrete or continuous
A discrete quantitative variable is one that has a finite number of possible values or which may have an infinite but countable number of values
Therefore;
1) The number of passengers which is countable and exact is a discrete quantitative variable
A continuous variable is one whose exact or accurate value range is infinite or a variable with a limitless value set such as the range of values between two real numbers
Therefore;
1) Amount of fuel used and 2) Time of flight are continuous quantitative variables.

The number 5 x 10⁶ is 10000 times greater than the number 5 x 10².
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the numbers are 5 x 10⁶ and 5 x 10². How many times the number is greater will be calculated by dividing the bigger number by the smaller number.
E = ( 5 x 10⁶) / ( 5 x 10² )
E = 10000
Therefore, the number 5 x 10⁶ is 10000 times greater than the number 5 x 10².

Please help Thank you
Answer:
12+2x=46 x=17 cookies
Step-by-step explanation:
First you are going to double the number of students because each student is getting 2 cookies. Then you will subtract 12 from 46 and that gets you 34. Then you will divide 2 by 34 to get how many cookies she needs to bake. 17 more cookies. To check your work plug in 17 by the x. so 2 times 17 is 34 plus 12 is 46 so that answer is correct.

The pressure exerted on an object under water increases by 1 atmosphere every 33 feet below the surface of the water. At sea level, the pressure is l atmosphere. Which equation gives the total pressure p, in atmospheres, exerted on an underwater object at a depth of f feet below sea level? A) P 33 B) p 33f C) p 33f+ 1
Answer:
ooooooooooooooooooooooooo
The linear function that gives the total pressure exerted on an underwater object at a depth of f feet below sea level is given by:
p = l + 0.0303f.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem:
The pressure changes by 1 for each 33 feet of depth, hence m = 1/33 = 0.0303.The initial pressure is of l, hence b = l.Thus, the function is given by:
p = l + 0.0303f
