Answer:
[tex]25\%[/tex]
Step-by-step explanation:
Experimental probability represents probability based on an experiment conducted. In the question, it states 40 marbles were drawn and the graph shows that yellow was drawn 10 times. Thus, the experimental probability is [tex]\frac{10}{40}=\frac{1}{4}=\boxed{25\%}[/tex]
Answer:
25%

find surface area of the prism pls!!!!! explain too. I really need help!!!
Answer: 104 square inches
Step-by-step explanation:
The surface area of a prism is the sum of the surface are of all of it's faces.
We can turn that into this equation SA = 2(w x l) + 2(l x h) + 2(w x h) where w is width, l is length, h is height, and 2(w x l) is the top and the bottom surface areas, 2(l x h) is the left and right sides, and 2(w x h) is the front and back.
Substitute to get this: SA = 2(6 x 2) + 2(2 x 5) + 2(6 x 5)
Simplify with multiplication to get this: SA = 24 + 20 + 60
Simplify with addition to get this: SA = 104
Add the unit label and you get 104 square inches.

Part B: Describe how you can make the line of the best fit. write the approximate slope and y-intercept of the line of best fit. Show your work, including the points that you use to calculate the slope and y-intercept.
(please explain how you got the slope and y-intercept with the numbers from the question if you would like brainliest)
Answer: We are using a line regression tool to solve the parameters asked in the problem. We can use online tools or that of Excel. According to the tool, the best fit values are
Slope0.3848 ± 0.03956
Y-intercept0.6053 ± 0.6370
X-intercept-1.573
1/Slope2.598
Step-by-step explanation: Best fit lines make sure that the standard deviation at each point is minimum from the best fit line.
Answer:
Step-by-step explanation:
Slope0.3848 ± 0.03956
Y-intercept0.6053 ± 0.6370

[Help Please!] Find the value of x.
Answer:
x = 52
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles of a triangle
x+72 = 34+90
x +72 =124
Subtract 72 from each side
x = 124-72
x =52
Answer:
x = 52 degrees
Step-by-step explanation:
Let's first focus on the angle x + 72. Immediately adjacent to x + 72 is angle RQS. These two angles are "straight" in that they lie immediately adjacent to one another and add up to 180 degrees. Then angle RQS can be expressed as
180 degrees - (x + 72 degrees), or 108 - x degrees.
The three interior angles of the triangle must add up to 180 degrees. Hence
108 - x degrees + 34 degrees + 90 degrees = 180 degrees, and so:
108 - x + 34 = 90
This yields x = 52 degrees.

The following triangle is an isosceles triangle. What is the length of the missing side?
A. 4 in
B. 37°
C. 53°
D. 11 in
Answer:
D.11 in
Step-by-step explanation:
isosceles triangles have two congruent sides
The missing side length is congruent with the longer side ( this is pretty obvious )
If the longer side has a length of 11in and the missing side is congruent to the longer side then the missing side length equals 11 in

I need help with find the area of the other shapes. Like you can give me an example of the width and lenth like this (8:7) and I'll put a pic of what I've got so far and I need you to do what I did please.I really need help.
You must include the following items: • At least 10 shapes in which you can calculate the area (label the dimensions for each shape in feet 1 cm=3.25feet) o 2 rectangles o 1 rhombus o 3 triangles (1 must include a fractional base) o 2 trapezoids (1 base must be a decimal) o 1 pentagon o 1 irregular polygon in which you’ll have to decompose into smaller shapes. And if my pic ain't clear enough sorry.
