1 and 3
Step-by-step explanation:
Ms. Pearson kept track of student absences versus final average grades in her math dass for one semester, The
data is shown in the table below
The correct statement about the data collected by Ms. Pearson is that there is no association between a student's absences and the final average grades.
When do variables have a linear relationship?The equation that represents a linear relationship is: a + bx
Where x represents the rate of increase. Thus, for linear equations, the functiion increases by a constant term.
Looking at the table, the average final grade does not increase by a constant term.

Ms Alvarez’s math class surveyed 10 students in 6th grade and 10 students in 7th grade

I'm struggling with this question, if someone could help me that'd be great! :)
Answer:
t = 3 seconds
Step-by-step explanation:
You can think of this as a quadratic and find the zeros. i will use x and y to make it easier.
y = -16x^2 + 48x
y = (x)(-16x+48)
y = (-16)(x)(x-3)
This means your zeros are at x = 0 and x-3 = 0, so 0 and 3.
0 is when the ball leaves the ground, so 3 is when it returns.
What value of x makes this equation true?
5x+3=2x-3
Answer:
-2
Step-by-step explanation:
[tex]5x+3 = 2x -3 \\\\\implies 5x -2x = -3 -3\\\\\implies 3x = -6\\\\\implies x = -\dfrac 63 =-2[/tex]
Let's solve this equation.
Step 1
Move the numbers to the right:-
5x=2x-3-3
Step 2
Move the x's to the left
5x-2x=-3-3
Notice I use the opposite operation :)
Step 3
Combine like terms
3x=-6x
Step 4
Divide both sides by 3
x=-2
That's the value of x that makes the equation true.
note:-Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I'll comment and/or edit my answer :)

Someone want to help with number 1
Answer:
95 in²
Step-by-step explanation:
The total area of a pyramid is the sum of the areas of the triangular faces and the area of the base.
__
face areaHere, each triangular face has a base of 5 in, and a slant height of 7 in. Its area will be given by the area formula for a triangle:
A = 1/2bh
A = 1/2(5 in)(7 in) = 35/2 in² . . . . area of one of four congruent faces
__
base areaThe area of the base is that of a square with 5-inch sides. It is given by the formula ...
A = s²
A = (5 in)² = 25 in²
__
total areaThen the total surface area is .
area of base + 4 × triangle area
= 25 in² + 4(35/2 in²) = 95 in² . . . . . surface area of the pyramid

The algebraic expression of the SUM is n²+2n. What is the common difference and first term
Answer:
see explanation
Step-by-step explanation:
substitute n = 1, 2 into the sum rule
1² + 2(1) = 1 + 2 = 3 , then
a₁ = 3
2² + 2(2) = 4 + 4 = 8 , then
a₁ + a₂ = 8
3 + a₂ = 8 ( subtract 3 from both sides )
a₂ = 5
then
common difference d = a₂ - a₁ = 5 - 3 = 2
First term is 3 and common difference = 2

When you use a graphing calculator to construct a 95% confidence interval for μMajor – μMinor = the true difference in the mean healing time will be 1.406, 5.369.
What is a Graphing Calculator?A graphing calculator is known to be a kind of handheld computing device that is used for plotting of graphs, handling simultaneous equations, etc.
Note that by inputting those numbers such as Major: 8, 9.5, 10, 12, 11.5 Minor: 6, 7, 5.5, 8, 9, 6, 7, 6 , following the right equation on the graphing calculator, one can be able to construct a 95% confidence interval for μMajor – μMinor = and the the true difference in the mean healing time will be found to be 1.406, 5.369.

Answer:
23.3786
Step-by-step explanation:
tan33° = x÷36
x = tan33°×36
x = 23.3786
Answer:
23.36
Step-by-step explanation:
We have three things on the diagram :
Angle = 33°Length of adjacent side = 36Length of opposing side = xWhen the opposing side length and adjacent side length is given, always use the tan ratio.
tan = opposite / adjacentFirst, find the numerical value of tan(33°)
tan(33°) = 0.6494 = 0.649Solving :
tan(33°) = x/36 = 0.649⇒ x = 0.649 x 36⇒ x = 23.364 = 23.36what is 2x2x32 to the 2 power

The following three shapes are based only on squares, semicircles, and quarter circles. Find the perimeter and the area of each shaded part.
Answer:
Step-by-step explanation:
The total shaded area = area of the square - area of a circle
= 9^2 - π * 4.5^2
= 17.3827
The 2 shaded parts both have area 8.69 unit^2 ( to nearest hundred)
Perimeter:
The perimeter of the top shaded part
= AB + 1/2 circmference of the circle
= 9 + 1/2 * 2 π r
= 9 + 14.137
= 23.14 units ( to nearest hundredth)
The bottom part has the same perimeter.
Answer:
area: 17.38 cm²perimeter: 46.27 cmStep-by-step explanation:
You want the perimeter and area of the part of a 9 cm square remaining after a semicircle is removed from two opposite sides.
AreaThe shaded area is the area of the 9 cm square less the area of a 9 cm circle. That area is ...
A = s² - π(s/2)² = s²(1 -π/4) . . . . . where s is the side length of the square
A = (9 cm)²(1 -π/4) ≈ 17.38 cm²
The area is about 17.38 cm².
PerimeterThe perimeter is the circumference of the circle plus two sides of the square.
P = C +2s
P = πs +2s = s(π+2)
P = (9 cm)(π+2) ≈ 46.27 cm
The perimeter is about 46.27 cm.
