Help asap pls. The mean of a math test took by 50 students is 85% Two students got a 10% on the test. If those outliers were removed, what would the new mean be? Pls don't answer for points. And also DONT ANSWER TO ASK A QUESTION COMMENT IT. it takes away a chance for people who actually know the answer to answer
Answer:
okay I'm not 100% sure but I have a good idea (it's okay if u remove me it's just an educated guess)
89%
Step-by-step explanation:
if there were 100 students that would mean 1 student represented 1% of the results. so if there were 50 students 1 student would represent 2% of the results. so if two students were removed then that would mean the result would improve by a total of 4% which would get you 89%
These two screenshots both have the information you can use for the answer. The first screenshot is the chart and the second is the question.

Julius needs to determine how much information needs to be given about an isosceles triangle to be able to draw an isosceles triangle. He is looking at six different cases and is trying to determine if that amount of detail will allow him to construct just one isosceles triangle or if it allows for more than one isosceles triangle.
Case 1. The length of the two congruent sides and the measure of the included angle.
Case 2. The lengths of two non-congruent sides and the measure of the included angle.
Case 3. The lengths of two non-congruent sides.
Case 4. The measure of the two congruent angles and the included side.
Case 5. The measure of two non-congruent angles.
Case 6. The measure of two non-congruent angles and the included side.

more plz help i kinda suck at dependent and independent
Answer:
I think T is the independant and B is the dependant
Step-by-step explanation:
the amount of time they have is not changed, however the amount of bands they can fit into that time slot is undetermined and relies on the time they have
Answer:
the first option
Step-by-step explanation:
independent is something you can change OR determine
dependent is something that will happen BECAUSE of the independent and you can not change it
in this case- the sentence states that " the amount of time that the venue has been reserved for DETERMINES how many bands will play"
You can change or schedule how long you want to reserve the venue but how many bands that will play depends on the independent variable (t)
Thats why it say determines, because (t) determines or changes (b)

Answer:
53.12ft
Step-by-step explanation:
Area of triangle:
The formula to find the area of a triangle is 1/2bh
- We plug in the values given.
1/2 x 8 x 7
Which is 28ft.
Area of semicircle:
The formula to find the area of a semicircle is 1/2[tex]\pi[/tex][tex]r^{2}[/tex]
- We plug in the values given
1/2 x [tex]\pi[/tex] x [tex]4^{2}[/tex]
1/2 x 16[tex]\pi[/tex]
8[tex]\pi[/tex] or 8 x 3.14 = 25.12
In order to get the total area of the whole shape we need to add the areas of those two, which will be 25.12 + 28 = 53.12
