On a coordinate plane, a line with a 90-degree angle crosses the x-axis at (negative 4, 0), turns at (negative 1, 3), crosses the y-axis at (0, 2) and the x-axis at (2, 0).
What is the range of the function on the graph?
Answers
Answer:
B
Step-by-step explanation:
The range of the function is {0, 3}.
The range of a function on a graph is the set of all possible output values (y-values) that the function can take. To find the range of the given function, we need to determine the y-values corresponding to the points where the function is defined.
Let's analyze the points provided:
The line crosses the x-axis at (-4, 0). This means the function's y-value is 0 when x = -4.
The line turns at (-1, 3). This point is on the line, so the function's y-value is 3 when x = -1.
The line crosses the y-axis at (0, 2). This means the function's y-value is 2 when x = 0.
The line crosses the x-axis again at (2, 0). This means the function's y-value is 0 when x = 2.
Now, let's consider the intervals between these points:
a) When x < -4 (to the left of -4): The function's y-value is 0, as the line is horizontal at y = 0.
b) When -4 ≤ x < -1: The function's y-value starts at 0 and increases to 3, as the line rises from (−4, 0) to (−1, 3).
c) When -1 ≤ x ≤ 2: The function's y-value remains constant at 3, as the line is horizontal at y = 3 between (−1, 3) and (2, 3).
d) When x > 2 (to the right of 2): The function's y-value decreases from 3 to 0, as the line descends from (2, 3) to (2, 0) and further to the right.
So, the range of the function is {0, 3}.
In mathematical notation, the range is written as:
Range = {y | y = 0 or y = 3}

Answers
Answer;
m<EAD=29°
m<CAB=119°
Step-by-step explanation:
Angles on a straight line sum up to 180°
This implies that,
61°+90°+EAD=180°
151°+EAD=180°
Subtracting 151° from both sides,we obtain,
EAD=180°-151°
EAD=29°
Angles on a straight line add up to 180°.
this implies that,
CAB+61°=180°
Subtracting 61° from both sides,we obtain
CAB=180°-61°
CAB=119°
Thus,m<EAD=29° and m<CAB=119°
Answer:
29° and 119°
Step-by-step explanation:
Since CF is a straight line, then
90° + ∠ EAD + 61° = 180°, that is
∠ EAD + 151° = 180° ( subtract 151° from both sides )
∠ EAD = 29°
and
∠ CAB + 61° = 180° ( subtract 61° from both sides )
∠ CAB = 119°

A set of data with 1200 numbers is normally distributed with a mean of 27 and a standard deviation of 4. How many numbers in the data would you expect to be between 23 and 31?
What numbers would be between 19 and 35 as well?
Help!
Answers
Step-by-step explanation:
The mean is 27 and the standard deviation is 4.
23 is 1 standard deviation below the mean, and 31 is 1 standard deviation above the mean. According to the empirical rule, 68% of the population is between -1 and +1 standard deviations.
68% of 1200 is 816.
19 is 2 standard deviations below the mean, and 35 is 2 standard deviations above the mean. According to the empirical rule, 95% of the population is between -2 and +2 standard deviations.
95% of 1200 is 1140.
How do I solve this equation 1x - 15 = 5x + 13
Answers
Answer:
x = -7
Step-by-step explanation:
This is a multi-step equation in algebra. We are expected to isolate the given variable and find the constant value that it is equal to. In order to do this, we can follow some steps:
1x - 15 = 5x + 13 Subtract 5x on both sides of the equation.
-4x - 15 = 13 Add 15 to both sides of the equation.
-4x = 28 Divide by -4 on both sides of the equation.
x = -7
You can input this value and make sure that the answer is correct.
1(-7) - 15 = 5(-7) + 13
-7 - 15 = -35 + 13
-22 = -22
-22 equals -22, so x = -7 is the solution to the equation.
Answer:
x= -7
Step-by-step explanation:
We are given the equation:
1x-15=5x+13
We want to solve for x. Therefore, we must isolate x on one side of the equation.
First, let’s move all the terms with variables to one side. Subtract 1x from both sides.
1x-1x-15=5x-1x+13
-15= (5x-1x)+13
-15=4x+13
Next, move all the constants, or terms without variables to one side. Subtract 13 from both sides.
-15-13=4x+13-13
-15-13=4x
-28=4x
Finally, divide both sides by 4. We should divide because x is being multiplied by 4 and the inverse of multiplication is division.
-28/4=4x/4
-28/4=x
-7=x
Let’s check our solution. Plug -7 in for x and solve.
1x - 15 = 5x + 13
1(-7) - 15 = 5(-7) + 13
-7-15=5(-7)+13
-22= 5(-7)+13
-22= -35+13
-22=-22
This checks out, so we know our solution is correct.
The solution to 1x - 15 = 5x + 13 is x= -7

Step-by-step explanation:
4 tickets equals 48 so to get the price for each ticket divide:

Answers
Answer:
B. 1-third
Step-by-step explanation:
The formula for probability = Number of favorable outcomes/ Total number of outcomes
From the question, we are told that:
Owen knows he only has three pencils in his backpack, and they are all yellow. Hence, total number of outcomes = 3
He reaches into his backpack without looking and takes out a pencil.
Hence, total number of favorable outcomes = 1
What is the probability that the pencil was yellow?
Probability ( That the pencil is yellow) =
Number of favorable outcomes/ Total number of outcomes
= 1/3
Therefore, the probability that the pencil was yellow is 1/3 or one - thirds

Equation of a Straight Line
1.1 Solve y-x-1 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-x-1 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 1/1 so this line "cuts" the y axis at y= 1.00000
y-intercept = 1/1 = 1.00000
Calculate the X-Intercept :
When y = 0 the value of x is 1/-1 Our line therefore "cuts" the x axis at x=-1.00000
x-intercept = 1/-1 = -1.00000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.000 and for x=2.000, the value of y is 3.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 3.000 - 1.000 = 2.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 2.000/2.000 = 1.000
Geometric figure: Straight Line
1. Slope = 2.000/2.000 = 1.000
2. x-intercept = 1/-1 = -1.00000
3. y-intercept = 1/1 = 1.00000
The equation of the line that passes through the given points will be y=1.5x-4.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
A linear equation has the form y = mx + b in the slope-intercept format. X and Y are the variables in the equation. The values m and b represent the line's slope (m) and the value of y when x is 0.
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that the line passes through (0,4) and (2,7)
The slope of the line is,
m = (7-4)/(2-0)
m=3/2
m=1.5
The equation of the line passes through the points (0,4) and (2,7) and has a slope of 1.5 will be,
y-4=1.5(x-0)
y-4=1.5x
y=1.5x-4
Thus, the equation of the line that passes through the given points will be y=1.5x-4.
