What is the value of y?
Answer:
A-54
Step-by-step explanation:
triangle angle total is 180° the subtract 72 is 108 and divide by 2 is 54
Answer:
A. 54°
Step-by-step explanation:
a triangle is 180°.
180-72 = 108
there's 2 y's so you'd divide by 2.
108/2 = 54

When a number x is multiplied by 6, the result is 3/8 What is the value of x?
Answer:
1/16.
Step-by-step explanation:
6x = 3/8
Divide both sides by 6:
6x / 6 = 3/8 / 6
x = 3/8 * 1/6
= 3/48
= 1/16.
In the bin there is a 45% chance of randomly selecting ripe avocados. If you are picking avocados from the bin, you keep inspecting avocados and stop upon finding a ripe avocado. If you buy a bag of avocados, you do not inspect the fruit until you get home and inspect the bag of avocados all at once.
1. What is the probability that you have inclusively between 2 and 3 ripe avocados from your bag of 5 avocados?
2. What is the probability that you inspect inclusively 3 and 3 avocados from the bin?
Answer:
0.6125
Step-by-step explanation:
We have,
P(ripe avocados) = 0.45 , n = 5
by binomial distribution,
P(x=k) = [tex]${\overset{n}C}_k P^k(1-P)^{n-k}$[/tex]
P(2 ≤ x ≤ 3) = P(x=2) + P(x=3)
P(x=2) = [tex]${\overset{5}C}_2(0.45)^2(0.55)^3$[/tex]
= 10 x (0.45)² x (0.55)³
= 0.3369
P(x=3) = [tex]${\overset{5}C}_3(0.45)^3(0.55)^2$[/tex]
= 10 x (0.45)³ x (0.55)²
= 0.2756
So, P(2 ≤ x ≤ 3 ) = 0.3369 + 0.2756
= 0.6125

Answer:
Step-by-step explanation:
Look at tenth place. If it is 5 , 6 ,7 , 8, 9 ( 5 or more than 5)then add 1 to the whole part and that is your answer
If it is 0,1,2,3,4, then write the whole number as it it.
a) 8.71
tenth place is 7 and it is more than 5. so, add 1 to the whole part. 8+1 = 9
8.71 = 9
b) 26.01
Tenth place is 0 and it is less than 5.So, write the whole number as it is.
26.01 = 26
c) 69.48 = 69 { 4 is less than 5}
d) 103.72 = 104 { 7 >= 5}
e) 49.84 = 50 { 8 >= 5}
f)101.35 = 101
g) 39.814 = 40
h)1.23 = 1

What the answer? 8x-(2x-3)=12
Answer:
x= 3/2 or 1.5
Step-by-step explanation:
First of all, you can take out the parenthesis because 8x is subtracting 2x-3.
8x-2x-3=12
6x-3=12
+3 +3
6x= 15
6x/6= 15/6
x= 3/2 or 1.5

What number is 10 times greater than 300?
The inequality for the given statement is 10x>300.
We need to find what number is 10 times greater than 300.
What is inequality?In Mathematics, equations are not always about being balanced on both sides with an 'equal to' symbol. Sometimes it can be about a 'not an equal to' relationship like something is greater than the other or less than. In mathematics, inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions.
Let the unknown number be x.
Now, 10 times the number=10x
The number is 10 times greater than the 300.
That is, 10x>300
Therefore, the inequality for the given statement is 10x>300.

Write an equation for the parent function y = x^ 2 stretched by a factor of 6 and shifted down 4 units?
Answer:
Translations
y = f (x) + k up k units
y = f (x) - k down k units
y = f (x + h) left h units
y = f (x - h) right h units
Stretches/Shrinks
y = m·f (x) stretch vertically by a factor of m
y = ·f (x) shrink vertically by a factor of m (stretch by
y = f (x) stretch horizonally by a factor of n
y = f (nx) shrink horizontally by a factor of n (stretch by )
Reflections
y = - f (x) reflect over x-axis (over line y = 0)
y = f (- x) reflect over y-axis (over line x = 0)
x = f (y) reflect over line y = x

Evaluate f(x)=-2×+5 for f(-5)
f(-5) = 15 (A)
Step-by-step explanation:f(x) = - 2x + 5
replace x = - 5
f(-5) = -2(-5) + 5
(-)(-) = +
f(-5) = 10 + 5
f(-5) = 15 (A)
f(-5) = -2(-5) + 5
(-)(-) = +
f(-5) = 10 + 5
f(-5) = 15 (A)

Solve the equation algebraically (x-8)^2=25
Hey there!
ANSWER: [tex]x=8,13[/tex]EXPLANATION:[tex](x-8)^2=25[/tex]
To solve this equation, you will need to simplify both sides.
[tex]x^2-16x+64=25[/tex]
Now we will need to minus(subtract) 25 from both sides of the equation.
[tex]x^2-16x+64-25=25-25=x^2-16x+39=0[/tex]
Now we will need to factor out the left side.
[tex](x-3)(x-13)=0[/tex]
In our last step, we will need the set factors equal to zero.
[tex]x-3=0\\x-13=0\\x=3(ANSWER)\\x=13(ANSWER)[/tex]

The following statements are true:
Line AB and line CG are parallel.
Line CG and line RS are perpendicular.
Line segment CG lies in plane X.
What are parallel lines?When the two lines lie in the same plane then they are said to be parallel lines.
Given information:
Planes X and Y intersect at a right angle.
Lies in plane X and do not intersect.
A) Line AB and Line CG are parallel: As both lines, AB and CG lie in plane X. Thus both are parallel and options A is the correct option.
B) Line AB and Line RS are parallel: As the line, AB lies in the plane X and the line RS lies in the plane Y. Thus both are perpendicular and not parallel. Option B is the incorrect option.
C)Line CG and Line RS are perpendiculars: As the line CG lies in the plane x and the line RS lies in the plane Y. Thus both are perpendicular. Option C is the correct option.
D) Line AB and Line RS must intersect: line RS passes from the middle of the plane Y and line AB passes from the left of the plane X centre. Thus they do not intersect each other. Option D is the incorrect option.
E) Line segment CG lies in plane X: As shown in the diagram, line CG lies in plane X. Thus option E is the correct option.
F) Line segment RS lies in plane X: As shown in the diagram, and the line lies RS in plane Y. Thus option F is the incorrect option.
Hence, the following statements are true:
Line AB and line CG are parallel.
Line CG and line RS are perpendicular.
Line segment CG lies in plane X.
