The following frequency distribution analyzes the scores on a math test. Find the class midpoint of scores interval 95-99
The class midpoint of scores interval 95-99 is 97
How to determine the class midpoint?The missing frequency table in the question is:
Score Number of students
40-59 2
60 - 75 4
76 - 82 6
83 - 94 15
95 - 99 5
The midpoint is calculated as:
Midpoint = 0.5 *(Upper interval + Lower Interval)
For interval 95 - 99, we have:
Midpoint = 0.5 *(99 + 95)
Evaluate
Midpoint = 97
Hence, the class midpoint of scores interval 95-99 is 97

A 4 inch by 6 inch picture is placed in a frame that creates a uniform border of x inches around the picture. The area of the entire frame (including where the picture is placed) is equal to 55.25 square inches.
The complete question is
"A 4 inch by 6 inch picture is placed in a frame that creates a uniform border of x inches around the picture. The area of the entire frame (including where the picture is placed) is equal to 55.25 square inches.
What will be the width and length of the frame?"
The width of the frame is 4+2x, and the length of the frame is 6+2x.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
We know that the picture is 4 inches wide and 6 inches long.
Since there is a uniform border of x inches around the picture, so we must add 2x inches to each dimension.
The area will be = (4+2x)(6+2x) = 55.25
Therefore, the width of the frame is 4+2x, and the length of the frame is 6+2x.

14. Find 5he equation of the parabola with a vertex at (-4,-1) and passing through the point (-2, -3).
Answer:
=> the passing point's y cord is lower than vertex, meaning it is a reflection
[tex]y=-a\left(x+h\right)^{2}-k[/tex]
=>Apply the vertex to hk form
[tex]y=-a\left(x+4\right)^{2}-1[/tex]
=> Find a by plugging X and Y of the passing through point
[tex]-3=-a\left(-2+4\right)^2-1[/tex]
=> solve
[tex]-4a-1+1=-3+1[/tex]
[tex]a=\frac{1}{2}[/tex]
Therefore the equation for this is,
[tex]y=-\frac{1}{2}\left(x+4\right)^{2}-1[/tex]
Answer:
[tex]y=-\dfrac{1}{2}(x+4)^2-1[/tex]
Step-by-step explanation:
Vertex form: [tex]y=a(x-h)^2+k[/tex]
where:
[tex](h, k)[/tex] is the vertex[tex]a[/tex] is some constantGiven:
vertex = (-4, -1)point on parabola = (-2, -3)Substitute given values into the formula to find [tex]a[/tex]:
[tex]\implies -3=a((-2)-(-4))^2+(-1)[/tex]
[tex]\implies -3=a(2)^2-1[/tex]
[tex]\implies -3=4a-1[/tex]
[tex]\implies -2=4a[/tex]

What is the radius of a circle in which a 30° arc is 27 Inches long?
O 12 inches
O 2√3 inches
O24 inches
Answer:
Step-by-step explanation:
Formula
Arc length = (theta/360) * 2 * pI * r
Givens
Arc Length = 27 inches
theta = 30
r = ?
Solution
27 = (30/360) * 2 * 3.14 * r Reduce the right hand side
30 / 360 = 1/12 = 0.0833
Arc length = 0.0833 * 2 * 3.14 * r
Arc length = .5233 * r
27 = 0.5233 * r Divide both sides by 0.5233
27/0.5233 = 9.5233 r / 0.5233

The perimeter of the rectangle WXYZ that has vertices at W(−6, 1) , X(−1, 6) , Y(2, 3) , and Z(−3, −2) is 22.62 units.
What is rectangle?It is defined as the two-dimensional geometry in which the angle between the adjacent sides are 90 degree. It is a type of quadrilateral.
We have a rectangle WXYZ has vertices at W(−6, 1) , X(−1, 6) , Y(2, 3) , and Z(−3, −2) .
Using the distance formula:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Calculate the distance WX between (-6,1) and (-1,6)
WX = 7.07
The distance XY between (-1,6) and (2,3)
XY = 4.24
The distance YZ between (2,3) and (-3,-2)
YZ = 7.0
The distance ZW between (-6,1) and (-3,-2)
ZW = 4.24
Perimeter of the rectangle = 7.07+ 4.24 + 7.07 + 4.24 = 22.62 units
Thus, the perimeter of the rectangle WXYZ that has vertices at W(−6, 1) , X(−1, 6) , Y(2, 3) , and Z(−3, −2) is 22.62 units.

When (3x⁴ - 7x³ - 5x² + 19x - 10) is divided by (3x² + 2x - 5), the correct option is C. x² - 3x + 2.
How to get the value?To divide polynomial, it's important to set up the division problem. In this case, you then divide the first term of the dividend by the first term of the divisor.
Here, the correct value is x² - 3x + 2. To confirm, we can multiply them. This will be:
= (3x² + 2x - 5)(x² - 3x + 2)
= 3x⁴ - 9x³ + 6x² + 2x³ - 6x² + 4x - 5x² + 15x - 10
Collect like terms
= 3x⁴ - 9x³ + 2x³ + 6x² - 6x² - 5x² + 4x + 15x - 10

Answer:
152
Step-by-step explanation: a circle is 360 degrees its just under the 180 degree mark, this is how i got through this unit geometry was pain
Answer:
152°
Step-by-step explanation:
Intercepted arc is going to be two times the inscribed angle. We can see that angle A is subtended by arc BCD. (See attached picture.)
Step 1: Find angle A.
Angles in quadrilateral add up to 360°.
m∠A + m∠B + m∠C + m∠D = 360°
m∠A + 120° + 104° + 60° = 360°
m∠A + 284° = 360°
m∠A = 76°
Step 2: Find the measure of arc BCD.
Intercepted arc is going to be two times the inscribed angle.
measure of arc BCD = 2 × m∠A = 2 × 76° = 152°

y=-2/3)x+ 2
y=-(3/2)x+ 2

In slope-intercept form y is isolated
So Let's solve for y.
[tex]2x+3y=6[/tex]
Step 1: Add -2x to both sides.
[tex]2x+3y+-2x=6+-2x\\3y=-2x+6[/tex]
Step 2: Divide both sides by 3.
