Answer:
There are total 55 counters out of which 11 are green and 44 are other color.
Step-by-step explanation:
This is a ratio and proportion question. There are c amount of counters in the box .
The chosen have the same ratio as in the box
Green : total
4: 20
11: x
Using cross product rule
x * 4= 20 *11
x= 20*11/4
x= 55
So there are total 55 counters out of which 11 are green and 44 are other color.
Benedict take 20 counters out of which 4 are green.
Total number of counters are 55 in which 11 counters are green and 44 counters are other color.
Ratio and proportion:There are c amount in a box.
11 of the counters are green.
We have to find number of counters.
[tex]\frac{c}{11}=\frac{20}{4}\\ \\ 4*c=20*11\\\\c=\frac{20*11}{4}\\ \\c=55[/tex]
Hence, total number of counters are 55 in which 11 counters are green and 44 counters are other color.

Answer:
Johnny has the greatest free throw
Step-by-step explanation:
Lets look at the 1/2 mark of each one
Johnnys half mark is 5/10 he has 8/10 so he’s ahead
Rays half mark is 1/2 he’s at 1/2 so he’s lower then johnny
Davids half mark is 10/20 he’s at 12/20 a little over
Davids= 6/10

Answer:
it takes 2.56 (or 2 14/25) months
Step-by-step explanation:
Edmond has $45 in his saving account. He wants to purchase a computer that costs $768. He starts to babysit for his cousin and gets paid $90/week. He plans to spend some money and deposit $75/ week in his account. Define a variable and write an equation and solve to find how many months it takes for him to buy the computer. Assume that every month has 4 weeks
Even though Edmond is getting $90 a week, he's only depositing $75
Based on this information your equation would be:
75w = $768 where w = week
To solve that divide 75 by 768
w = 10.24 or 10 6/25
If there are 4 weeks in a month then your new equation would be
w/4 = m where m = months
To solve this, substitute w for 10.24 or 10 6/25
(10.24)/4 = m
m = 2.56 or 2 14/25

[tex]SP\cong MO,\angle P\cong \angle O[/tex]
To find:
The additional pair of corresponding parts that needs to be congruent in order to prove that [tex]\Delta STP\cong \Delta MKO[/tex] by ASA.
Solution:
According to ASA, two triangles are congruent if their two corresponding angles are congruent and their included sides of those angles are also congruent.
In [tex]\Delta STP\text{ and }\Delta MKO[/tex],
[tex]\angle P\cong \angle O[/tex] [Given]
[tex]SP\cong MO[/tex] [Given]
Clearly, SP is between angle S and angle P, and MO is between angle M and angle O.
Then, [tex]\angle S\cong \angle M[/tex] as [tex]\Delta STP\cong \Delta MKO[/tex] by ASA.
Therefore, the additional pair of corresponding parts that needs to be congruent in order to prove that [tex]\Delta STP\cong \Delta MKO[/tex] by ASA is [tex]\angle S\cong \angle M[/tex].

What is the distance of the point P(x,y) from y axis? Wht does this even mean?
Answer:
The x value
Step-by-step explanation:
Basically, the question is asking you to find the straight line distance from the y axis to a given point. The y-axis on a coordinate plane is the axis that goes up and down, and the x axis is the one that goes left and right. In a coordinate pair (x,y), x is how far left or right the point is and y is how far up or down it is. so the point (3,9) is three to the right and three up. (See screenshot)
So, the distance that (3,9) would be from the y-axis would be how far right it is, or x, which is 3!

A biologist wonders if the life span of bats will be affected by two new food sources from invasive species moving into an area. To conduct the experiment, the biologist needs three treatment groups: a group where the diet will not include invasive species (control), a group where the diet will include one invasive species (treatment group 1), and another group where the diet will include the other invasive species (treatment group 2). The biologist chooses the first cloud-free night and catches the first 18 bats that fly out of a cave, placing them into three equal groups of six bats. To decide the treatment for each group, the biologist places three slips of paper labeled control, treatment group 1, and treatment group 2 in a hat and randomly selects 2 slips of paper. The first piece of paper gives the treatment for the first group, the second piece of paper gives the treatment for the second group, and the remaining treatment is given to the third group.
Which component is missing from the biologist’s process?
a.The biologist did not use proper labeling on the pieces of paper.
b.The biologist did not use the appropriate number of treatment groups.
c.The biologist did not randomly assign the individual bats to the treatment groups.
d,The biologist did not randomly choose the weather on the night for bat capture.
Answer:
D
Step-by-step explanation:
Every factor, besides for the factor you are testing for, must be the same for all of the groups and must be randomly selected. Choosing bats from one clear night isn’t random because a cloud free night might effect which bats first fly out of the cave.
It’s like surveying the first few people who walk out of a movie theater and asking if they thought the movie was good. Most likely not because they left so early/quickly. This can skew the results from being completely random and won’t reflect the entire population as a whole accurately.
Also, note that for every other answer choice, they are correct.
A - The biologist did use proper labeling
B - There are enough treatment groups
C - He did randomly assign 6 for each group
Therefore, by process of elimination, it is D.
I hope this helps! :)
The component that is missing from the biologist's process is: c. The biologist did not randomly assign the each of the bats to the treatment groups.
Importance of Random Assignment of Subjects into GroupsWhen carrying out a research study where you have groups created that you want to study, differences between and within groups can be satisfactory ensured that they are not systematic when subjects are randomly assigned to groups.
Thus, it gives the researcher the confidence that groups are the same in terms of variables, and any differences can be confidently ascribed to experimental treatments.
Therefore, the component that is missing from the biologist's process is: c. The biologist did not randomly assign the each of the bats to the treatment groups.Learn more about random assignment on:

I have no idea what piecewise functions are or how to solve them! Please explain how, thank you!
I'm willing to give up a lot of points to understand this, so please help me.
Answer:
A piece wise function is pretty easy
Think of it like as a lot of functions with inequalities.
So lets say for example
Your Going to a skate park that counts time
Up to 6 minutes costs $50
Over 6 and up to 15 minutes costs $80
Over 15 minutes costs $80 plus $5 per minute above 15 minutes
The function would look something like
H(t)={ $50 If T is less then Or equal to 6
$80 If T is greater then 6 AND T less then or equal to 15
$80+$5(T-15) If T is greater then 15 }
Just simplify the worded problems into inequalities
And then a question would be something like, you visit for 13 minutes, how much would you pay?
It‘d be $80 becuase the chart says, if T (13) is greater then 6 And less then or equal to 15, its be 80 dollars.
