Answer:
Shawn and Brielle are correct, since absolute has the following property: [tex]|a| = |-a|[/tex], [tex]a\in \mathbb{R}[/tex]
Step-by-step explanation:
Both Shawn and Brielle are correct, because the absolute value has the following property:
[tex]|a| = |-a|[/tex], [tex]a\in \mathbb{R}[/tex]
Which means that [tex]|x|[/tex] and [tex]|-x|[/tex] gives the same result.
Answer:
Both Shawn and Brielle are correct. The absolute value parent function is symmetric with respect to the y-axis, and the absolute value of negative x is a reflection across the y-axis, so the graph of these two functions would look identical. Additionally, if you wanted to verify that the given points are on the graph of both functions, you could substitute them into the functions to get true statements.

Which graph represents all of the solutions of
Step-by-step explanation:
Solve the inequality for b
-15b <= 45 divide both sides by -15, since you're dividing by a negative number switch the direction of the sign.
b >= -3
So, your number line is all values of b greater than or equal to -3. Since it is including -3, the circle will be filled and increase to the positive.
jester has a piece of wood measuring 1 and 2/3 m.he needs to cut in pieces measuring 3/4 m. long.how many pieces of wood did jester cut.
Answer:
2
Step-by-step explanation:
Given that,
Jester has a piece of wood measuring 1 and 2/3 m = 5/3 m
He needs to cut in pieces measuring 3/4 m
We need to find the number of pieces. Let there are x no. of pieces.
[tex]x=\dfrac{\dfrac{5}{3}}{\dfrac{3}{4}}\\\\=\dfrac{5}{3}\times \dfrac{4}{3}\\\\=2.23\[/tex]
or
x = 2
So, he will cut it into approx 2 pieces.
What is the image of (−8,−8) after a dilation by a scale factor of 1/2 centered at the origin?
Answer:
(-4,-4)
Step-by-step explanation:
Since this is centered at (0,0), we have to multiply the x and the y coordinates by the scale factor.
-8 × 1/2 = -4

Consider a binomial experiment with n = 5 trials where the probability of success on a single trial is p = 0.30. (a) Find P(r = 0). (b) Find P(r ≥ 1) by using the complement rule.
Answer:
0.16807 ; 0.83193
Step-by-step explanation:
Given that:
Number of trials, n = 5
Probability of success, p = 0.30
P(r = 0)
Using the binomial probability relation :
P(x =r) = nCr * p^r * (1 - p)^(n - r)
(a) Find P(r = 0).
P(r = 0) = 5C0 * 0.3^0 * (0.7)^(5- 0)
= 1 * 1 * 0.16807
= 0.16807
(b) Find P(r ≥ 1) by using the complement rule
P(r ≥ 1) = 1 - P(r = 0)
P(r ≥ 1) = 1 - 0.16807
P(r ≥ 1) = 0.83193
The angle measurements in the diagram are represented by the following expressions.
B

Solve for x and then find the measure of
Answer:
[tex]x = 20^{\circ}[/tex]
[tex]\angle A = 150^{\circ}[/tex]
Step-by-step explanation:
Given
[tex]\angle A = 8x - 10[/tex]
[tex]\angle B = 3x + 90[/tex]
See attachment
From the attachment A and B are vertically opposite.
This implies that:
[tex]\angle A = \angle B[/tex]
Substitute values for A and B
[tex]8x - 10 = 3x + 90[/tex]
Collect Like Terms
[tex]8x - 3x = 10 + 90[/tex]
[tex]5x = 100[/tex]
Solve for x
[tex]x = \frac{100}{5}[/tex]
[tex]x = 20^{\circ}[/tex]
Substitute 20 for x in [tex]\angle A = 8x - 10[/tex]
[tex]\angle A = 8 * 20 - 10[/tex]
[tex]\angle A = 150^{\circ}[/tex]

Find the slope intercept equation of the line
PLEASE HELP ME!!!!!
Answer:
y = -x + 6Step-by-step explanation:
Slope-intercept form:
y = mx + b, where m is slope and b is y-interceptWe see on the graph y-intercept is b = 6, point (0.6)
To find the slope we need a second point, choosing point (5, 1)
Using slope formula:
m = (1- 6)/(5 - 0) = -5/5 = -1So the line is:
y = -x + 6Answer:
y = -4/5x + 5
Step-by-step explanation:
the formula for slope intercept is y=mx+b.
m represents the slope of the line and b is the y intercept. all you have to do is replace those variables.
the y intercept is the point where the line crosses the y-axis (the line going up and down on the graph). (0,5) is the y intercept and so 5 would replace b in y=mx+b
so far we have y=mx+5
The slope is the vertical change between two points is called the rise, and the horizontal change is called the run. Starting from a point on the line you would move vertically until you're in line with another point. In this case, let's just use (0,5) from before. You would go up four to line up with a point. Then, move horizontally to meet up with the point and count the units, which is five here. And so, the slope would be 4/5.
And then you get the equation:
y=4/5x+b

ITS UR ANSWER!,✌✌
There are two identical bottles. One bottle contains 2 green balls and 1 red ball. The other contains 2 red balls. A bottle is selected at random and a single ball is drawn. What is the probability that the ball is red
Answer:
2/3
Step-by-step explanation:
P(b1) = probability of bottle 1 = 1/2
P(b2) = probability of bottle 2 = 1/2
Bottle 1 = 2 green, 1 red ; total = 3
P(red ball1) = 1/3
Bottle 2 : red balls = 2, total balls = 2
P(red ball2) = 2/2 = 1
P(red ball) = [p(b1) * p(redball1)] = 1/2 * 1/3 = 1/6
P(red ball) = [p(b2) * p(redball2)] = 1/2 * 1 = 1/2
1/6 + 1/2 = (1 + 3) / 6 = 4/6 = 2/3
Calculate the correlation coefficient, r, for the data below.
This question is incomplete, the complete question is;
Calculate the correlation coefficient, r, for the data below.
X = -10 -8 -1 -4 -6 -7 -5 -3 -2 -9
Y = -15 -13 4 -4 -7 -11 -6 -2 1 -13
Answer: the correlation coefficient, r, for the data is 0.9896
Step-by-step explanation:
Given the data in the question;
correlation coefficient r = ?
we know that, C_Coeff is;
r = [ (Zn(∑xy) - (∑x)(∑y) ] / [ √[( n∑x² - (∑x)²) ( n∑y² - (∑y)²)] ]
so ;
X Y X² Y² XY

-3 -2 9 4 6
-2 1 4 1 -2
-9 -13 81 169 117
∑ -55 -66 385 806 536
now we substitute our values into the formula
r = [ (10×536 - (-55)(-66) ] / [ √[( 10×385 - (-55)²) ( 10×806 - (-66)²)] ]
r = 1730 / √( 825 × 3704 )
r = 1730 / √3055800
r = 1730 / 1748.0846
r = 0.9896
Therefore the correlation coefficient, r, for the data is 0.9896
Name the factors in each of the following problems
A weather report stated that the monthly rain amounts for the past three months were 15.82 inches, 17.4 inches, and 9.56 inches.
What is the total amount of rainfall for the three months?
A. 27.12 inches
B. 41.178 inches
C. 42.42 inches
D. 42.78 inches
Answer:
42.78 inches
Step-by-step explanation:
The anount of rainfall for the past three months are
15.82 inches
17.4 inches
9.56 inches
Therefore the total amount of rainfall for the three months can be calculated as follows
= 15.82+17.4+9.56
= 42.78
Hence the total rainfall for three months 42.78 inches

i got the top one to the left (checking my answer)
Answer:
The top left one is correct.
Step-by-step explanation:
We can rewrite this as an algebraic expression simply so it's easier to read.
Let's say hopscotch is [tex]h[/tex]. Tag is 6 times [tex]h[/tex], or [tex]6h[/tex].
That means for every 1 unit of hopscotch, there are 6 units of tag.
The top left one is correct.
