Answer:
it is 5 units
Step-by-step explanation:
All you have to do for this one is subtract 6-1 which equal 5 units. This only works in this one because is says at the end -2 on both the numbers.

Can you guys tell me if the 6 graphs are functions or not ?
Answer:
in order from left to right : NO, NO, YES, NO, YES, NO
Step-by-step explanation:
here's how you can tell! if any point on the line (or singular point) lines up VERTICALLY with a different point, it automatically is not a true function. thats why a vertical slope is "undefined" because its not a function.

I Need Help! 50pts. Write a paragraph explaining how to graph and find the reference angle for the 435° angle on the unit circle.
Answer:
0° to 90°: reference angle = angle ,
90° to 180°: reference angle = 180° - angle ,
180° to 270°: reference angle = angle - 180° ,
270° to 360°: reference angle = 360° - angle .
Step-by-step explanation:
Definition of Reference Angle: Let θ be a non-quadrantal angle in standard position. The reference angle of θ is the acute angle θR that the terminal side of θ makes with the x-axis. If θ is in QI, θR = θ If θ is in QII, θR = 180° – θ or π – θ If θ is in QIII, θR = θ – 180° or θ – πThe reference angle of 240° is 60°. To find the reference angle of a given angle, A, with measure x°, we start by adding or subtracting. You can see that the terminal side of the 135° angle and the x-axis form a 45° angle (this is because the two angles must add up to 180°). This 45° angle, shown in red, is the reference angle for 135°.

There are 26 students in the class. What is the total number of boys in Ms. Perron’s class?
Help :'/
Answer:
Let the no. of students be X.
Boys = 60% of X .
So Boys = (60/100)*X.
So left 40% of students are girls and it is given they are 14.
So total students X= total boys + total girls.
X = (60/100)*X+14.
(40/100)*X = 14.
X = (14*100)/40.
X = 35.
X - (60/100)*X = 14.

Subtract (4x - 2y) from the sum of (10x - 2y) and (-3y)
Answer:
6x - 3y
Step-by-step explanation:
First find the sum
10x - 2y - 3y
10x - 5y
Now do the subtraction
10x - 5y - (4x - 2y) Remove the brackets.
10x - 5y - 4x + 2y
10x - 4x = 6x
-5y + 2y = - 3y

The measure of one angle of a right triangle is 42∘ more than the measure of the smallest angle. Find the measures of all three angles.
Answer:
Step-by-step explanation:
A ≤ B ≤ C
C = 90°
B = A+42°
A+B = 90°
A+(A+42) = 90°
A = 24°
B = A+42° = 66°
24, 66, 90 are the measure of all three angles of the right angle triangle
What is right-angle triangle?A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.
Given, The measure of one angle of a right triangle is 42∘ more than the measure of the smallest angle.
Let "x" be the smallest angle in a right angle triangle.
So, biggest angle in the triangle will be x +42
Since, sum of the all the angles in a triangle = 180
x + x+ 42 +90 = 180
2x + 42 = 90
2x = 48
x = 24
Measure of the smallest triangle =x = 24
Measure of the biggest angle = 24 + 42
Measure of the biggest angle = 66
therefore, The measure of all three angles of the right angle triangle are 24, 66, 90.

2g + h =2
g -h= -5
find g and h step by step explanation
Answer:
Step-by-step explanation:
2g + h = 2 --------------(I)
g - h = -5------------(II)
g = -5 + h
Plugin g = -5 + h in equation (I)
2(-5 + h) + h = 2 {Distributive property:a(b+c) = a*b +a*c}
(-5)*2 + h *2 + h= 2
-10 + 2h + h = 2
3h = 2 + 10
3h = 12
h = 12/3
h = 4
Substitute h= 6 in equation (I)
2g + 4 = 2
2g = 2 - 4
2g = -2
g = -2/2
g = -1

Use the GCF and rewrite: (22 + 12x)
A)
2(11 + 6x)
C) 5(4 +2x)
D) 46 + 2x)
B)
615 + 2x)
11
Answer:
A = 2(11 + 6x)
Step-by-step explanation:
GCF = Greatest Common Factor (remember example: 12 and 16 gcf = 4 because it is the largest number they have together. 12 = 4 * 3 and 16 = 4*4)
22 and 12's GCF is 2:
22 = 2*11
12 = 2*6
Using the distributive property, we can find out that A is the right answer.
However, let us check the other options:
B does not make sense because 6*5 is 30. 6 only applies to 12
C is not correct because it does not apply to 22 or 12
And D only applies to 12 as well because 4*3 = 12 but 4*6 is 24
A should be the answer so I hope this helps!
A library association plans to take an SRS of 150150150 adults from the population of adults in the US to see what proportion of adults sampled believe that public libraries help them learn new things. Suppose that 76\vv, percent of adults in the US believe that public libraries help them learn new things. What are the mean and standard deviation of the sampling distribution of the proportion of US adults who believe that public libraries help them learn new things
Answer:
Mean: =0.76
SD= (squarerootof) 0.76(0.24)/150
Step-by-step explanation:
The mean of the sampling distribution is 0.76 and the standard deviation is approximately 0.00344.
What is the standard deviation?The standard deviation mathematical and statistical analysis tool used to explain the diversity of treatments or values around the Mean is the standard deviation, which is also known as the square root of variance.
The mean of the sampling distribution of the proportion of US adults who believe that public libraries help them learn new things is equal to the proportion of all adults in the US who believe that public libraries help them learn new things, which is 76% = 0.76.
The standard deviation of the sampling distribution is equal to the standard error of the proportion, which can be calculated as follows:
standard error = √((76% × 24%) / 150)
= √((0.76 × 0.24) / 150)
= √(0.01824 / 150)
= √(0.0000121)
= 0.00344
Therefore, the standard deviation is approximately 0.00344.
