Answer:
A. The data are continuous because the data can take on any value in an interval.
Step-by-step explanation:
A continuous data is any data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous data.
Hence, the exact heights of different elephants represents a continuous data because the data can take on any value in an interval.
On the other hand, a discrete data is any data set in which the number of possible values are either finite or countable. Thus, a discrete data can only take on specific values. For example, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.
f(x)=2x+3
what is the value of f(-4)
Answer:
f(-4) = -5
Step-by-step explanation:
Step 1: Define
f(x) = 2x + 3
f(-4) is x = -4
Step 2: Substitute and Evaluate
f(-4) = 2(-4) + 3
f(-4) = -8 + 3
f(-4) = -5
Answer:f(-4) = -5
Step-by-step explanation:
Step 1: Define
f(x) = 2x + 3
f(-4) is x = -4
Step 2: Substitute and Evaluate
f(-4) = 2(-4) + 3
f(-4) = -8 + 3
f(-4) = -5

Micah is 4 more than twice Angela’s age. The sum of their ages is 40. Set up the problem, Write an equation, Solve the equation, Determine how old Micah and Angela are.
Answer:
Angela is 12 and Micah is 28.
Step-by-step explanation:
So, the problem tells us that Micah is four more than twice Angel's age, and the sum of both their ages is 40. So, if we use a to stand for Angela's age and m to stand for Micah's age, we can safely assume our equation will look like this:
(a × 2) + 4 = m. And once that is figured out, we use a + m = 40.
For right now, we can start just randomly entering in numbers for a. Let's try 10, for example.
(10 × 2) + 4 = 24.
But does 10 + 24 = 40? No, it equals 34. So we go higher.
(12 × 2) + 4 = 28.
Does 12 + 28 = 40? Yes, yes it does.
So we can say with all certainty that Micah is 28 years old, and Angela is 12.

A number line going from negative 5 to positive 5. The distance from negative 3 to 3 is labeled negative 6.
Answer:
ITS A
Step-by-step explanation:
The number line that will represent the absolute value will be-
the distance from negative 3 to 0 is labeled 3.
What is absolute value of a number?The absolute value of a number is the magnitude of number. Absolute value describes the distance from zero that a number is on the number line, without considering direction.
We have a graph represents the absolute value of –3.
For a number [x], such that [x] < 0, the absolute value would be -
v[a] = -x
So, for x = -3, the absolute value would be 3.
The number line that will represent the absolute value will be -
The distance from negative 3 to 0 is labeled 3.
Therefore, the number line that will represent the absolute value will be-
the distance from negative 3 to 0 is labeled 3.

In a board game a certain number of points is awarded to a player upon rolling a six sided die labeled 1 to 6 according to the function f(x)=2x+3 whereby is it he value rolled on the die fund and interpret the given functions values and determine an appropriate domain for the functions
Answer:
f(x) is the amount awarded to a player upon rolling the die
The domain of the function = 1, 2, 3, 4, 5, and 6
The values of the function are 5, 7, 9, 11, 13, and 15
Step-by-step explanation:
The given information includes;
The function f(x) = 2·x + 3
Given that f(x) is the amount awarded to a player upon rolling the die, and x = The value rolled on the die, we have;
The values of x are 1, 2, 3, 4, 5, and 6
The values of the function then becomes;
f(x) = 2·x + 3
{x = 1, 2, 3, 4, 5, and 6} {f(x) = 5, 7, 9, 11, 13, and 15}
Therefore, the domain of the function = 1, 2, 3, 4, 5, and 6
The values of the function are 5, 7, 9, 11, 13, and 15.

Answer:
f(-6) = -2
Step-by-step explanation:
plug in k value (-6)
f(-6) = -6/2 + 1
theres two ways to solve for this
one way:
convert the whole number 1 to an improper fraction
f(-6) = -6/2 + 2/2
combine like terms
f(-6) = -4/2
divide -4 by 2
f(-6) = -2
second way:
divide -6 by 2
f(-6) = -3 + 1
combine like terms
f(-6) = -2
either way you get the same answer
use whichever is easiest for you

An acorn is falling from 13 feet in the air. If it descends 4.8 feet every second, write and solve an equation to determine how long it will take for the acorn to be 1 foot above the ground. please put the equation and answer please.
Using a linear function, it is found that:
The equation that has to be solved is: [tex]-4.8t + 13 = 1[/tex]It takes 2.5 seconds for the acorn to be 1 foot above the ground.--------------------------------
A linear function modeling the height after t seconds has the following format:
[tex]h(t) = at + h(0)[/tex]
In which:
a is the slope, which is the rate of change of the height.h(0) is the initial height.The acorn is falling from 13 feet, thus [tex]h(0) = 13[/tex]It descends at a rate of 4.8 feet every second, thus the slope is negative, that is, [tex]a = -4.8[/tex]The equation for the height after t seconds is:
[tex]h(t) = -4.8t + 13[/tex]
The acorn is 1 foot above ground when: [tex]h(t) = 1[/tex]Thus:
[tex]h(t) = -4.8t + 13[/tex]
[tex]1 = -4.8t + 13[/tex]
[tex]-4.8t + 13 = 1[/tex]
[tex]4.8t = 12[/tex]
[tex]t = \frac{12}{4.8}[/tex]
[tex]t = 2.5[/tex]
It takes 2.5 seconds for the acorn to be 1 foot above the ground.

The question just asks “Find QT” pls help
Answer:
QT = 21
Step-by-step explanation:
Because the left section is technically just a extension of the right triangle, the two triangles (PRQ and SRT) are similar, so the ratio between the sides will be similar as well.
The small triangle (SRT) has a ratio of 8/7 between its top side SR (40) and its bottom side TR (35). This means that the top and bottom side of the triangle PRQ will have the same ratio, and since we already known PR (24+40), we can write an equation to solve for QR:
[tex]\frac{SR}{TR} =\frac{PR}{QR} \\\\\\frac{40}{35}=\frac{64}{?}[/tex]
[tex]\frac{8}{7} =\frac{64}{?}[/tex]
64/8=8
This means so get our unknow length, we will need to multiply 7 by 8.
7*8=56
[tex]\frac{8}{7} =\frac{64}{56}[/tex]
This means that the side QR is 56, and since we know TR is 35, we simply need to subtract 35 from 56 to find QT: 56-35= 21
PS and QT also have the same ratio: 24/21 = 8/7 so we know that this is correct.

Irina rode her bike to work at an average speed of 16 miles per hour. It started to rain, so she got a ride home along the same route in her coworker's car at an average speed of 27 miles per hour. If Irina's ride home in the car took 24 minutes (0.4 of an hour), how many hours was her bike ride to work, to the nearest tenth of an hour? 0.2 of an hour 0.4 of an hour 0.6 of an hour 0.7 of an hour
Answer:
0.7 hours
Step-by-step explanation:
The computation of the number of hours is shown below:
As we know that
Time = Distance ÷ speed
where,
Distance is
= 27 miles × 0.4
= 10.8 miles
ANd, the speed is 16 miles per hour
So, the number of hours is
= 10.8 miles ÷ 16 miles per hour
= 0.675 hours
= 0.7 hours
Hence, the number of hours is 0.7 hours
Answer:
0.7 hours

Please help due tonight!!
Answer:
Step-by-step explanation:
x+ y+z=19 ...(1)
2x+6y+z=12 ...(2)
3x+8y+z=-14 ...(3)
(2)-(1) gives
x+5y =-7 ...(4)
(3)-(1) gives
2x+7y= -33 ...(5)
multiply (4) by 2
2x+10y=-14 ...(6)
(6)-(5) gives
3y=19
y=19/3
x+95/3=-7
x=7+95/3=(21+95)/3=116/3
from (1)
116/3+19/3+z=19
(116+19)/3+z=19
135/3+z=19
45+z=19
z=19-45=-26
