Answer:
lower limit = 5
upper limit = 10
class mark = lower limit + upper limit ÷ 2 = 7.5
class size = upper limit - lower limit
= 10-5 = 5

Answer:
D. 5.4
Step-by-step explanation:
The point U divides segment SP into the ratio 1 : 2. So, segment SU is 1/2 the length of segment UP.
SU = UP/2 = 3.6/2 = 1.8
The length of PS is ...
PS = PU +US = 3.6 +1.8
PS = 5.4

Find the measures of
Answer:
Step-by-step explanation:
Measure of an inscribed angle intercepted by an arc is half of the measure of the arc.
From the picture attached,
m(∠A) = [tex]\frac{1}{2}m(\text{arc BD})[/tex]
= [tex]\frac{1}{2}[m(\text{BC})+m(\text{CD}][/tex]
= [tex]\frac{1}{2}[55^{\circ}+145^{\circ}][/tex]
= 100°
m(∠C) = [tex]\frac{1}{2}[(360^{\circ})-m(\text{arc BCD})][/tex]
= [tex]\frac{1}{2}(360^{\circ}-200^{\circ})[/tex]
= 80°
m(∠B) + m(∠D) = 180° [ABCD is cyclic quadrilateral]
115° + m(∠D) = 180°
m(∠D) = 65°
m(arc AC) = 2[m(∠D)]
m(arc AB) + m(arc BC) = 2(65°) [Since, m(arc AC) = m(arc AB) + m(arc BC)]
m(arc AB) + 55° = 130°
m(arc AB) = 75°
m(arc ADC) = 2(m∠B)
m(arc AD) + m(arc DC) = 2(115°)
m(arc AD) + 145° = 230°
m(arc AD) = 85°

Solve the system of equations.
y = x2 + 3x - 4
y= 2x - 4
Answer:
The two solutions are
(0,-4) and (-1,-6)
Step-by-step explanation:
The ys have to be equal so you can equate the right hand side.
x^2 + 3x - 4 = 2x - 4 Add 4 to both sides
x^2 + 3x = 2x Subtract 2x from both sides
x^2 + 3x - 2x = 0 Combine
x^2 + x = 0 Factor
x(x + 1) =0
Just to show you that these two points really are the solutions, you can see the graph below
x has 2 values
x + 1 = 0
x = - 1
or
x = 0
Now solve for y
y = 2x - 4
Let x = 0
y = - 4
Let x = - 1
y = 2x - 4
y = -2 - 4
y = - 6
The blue is y = x^2 + 3x - 4
The green line is y = 2x - 4

Question Two please help
Answer:
The similarity statement is RTS and ACB. Other options are correct
Correct answer gets brainliest and 5 starts
Answer:
A
Step-by-step explanation:
The unit price will be the slope of the line which is 8, so the unit price is $8/1 lb
I need help I don't understand it.
These angles are corresponding angles, and we know that corresponding angles are equal when a transversal intersects two parallel lines.
So,
8x - 12 = 6x + 8
=> 8x - 6x = 8 + 12
=> 2x = 20
=> x = 20/2
=> x = 10
So, the value of x is 10.

Well explained answer will be marked as brainliest .
Answer:
Use the slope formula:
m = (y₂ - y₁)/(x₂ - x₁)The first one:
m = (-2 - 6)/(3 - 5) = -8/-2 = 4The second one:
m = (-7 - 4)/(4 - (-3)) = -11/7Answer:
Step-by-step explanation:
1) (x₁,y₁) = (5 , 6) & (x₂,y₂) = (3 , -2)
[tex]Slope = \dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{-2-6}{3-5}\\\\=\dfrac{-8}{-2}\\\\=4[/tex]
2) (x₁,y₁) = (-3, 4) & (x₂,y₂) = (4 , -7)
[tex]Slope= \dfrac{-7-4}{4-[-3]}\\[/tex]
[tex]= \dfrac{-11}{4+3}\\\\=\dfrac{-11}{7}[/tex]

Basically, everything except choice A.
=========================================================
Explanation:
All exponential functions can be written into the form y = a*b^x
The b term determines if we have growth or decay.
If 0 < b < 1, then we have decay. If b > 1, then we have growth.
------------
For choice A, we have b = 1.7 which satisfies b > 1. This represents growth. So we cross choice A off the list.
Choice B looks almost identical since it appears b = 1.7 here as well, but note the negative exponent. It might help to rewrite choice B into y = 3( 1.7^(-2) )^x and note how b = (1.7)^(-2) = 0.346 approximately. This represents decay.
Choice C has b = 1/3 = 0.33 approximately which is also decay.
Finally, choice D has b = 2^(-1) = 1/(2^1) = 1/2 = 0.5 which is also decay.
Choices B through D have b values such that 0 < b < 1.
------------
Check out the graph below. It visually confirms the answers mentioned earlier. A growth function goes uphill as we move to the right, while a decay function moves downhill while moving to the right.
I used GeoGebra to make the graph.

How many integers $n$ satisfy $-4n\ge 12$ and $n+5>2$??
-4n ≥ 12 ==> n ≤ -3
n + 5 > 2 ==> n > -3
But n cannot be both less than/equal to -3 AND greater than -3, so there are no integers n that satisfy these inequalities.

What is the area of trapezoid DEFG?
PLEASE SO THIS ASAP!!!

Answer:
Area = 35 cm^ 2
Step-by-step explanation:
Area = 1/2(a+b) x h
1/2 (5+9) x 5
= 35 cm^ 2
Answered by G a u t h m a t h
Answer:
A = 35 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂)
where h is the perpendicular height between the bases and b₁, b₂ are the bases.
Here h = 5 , b₁ = 9 and b₂ = 5 , then
A = [tex]\frac{1}{2}[/tex] × 5 × (9 + 5) = 2.5 × 14 = 35 cm²
