200 applicants applied to volunteer at an international tennis tournament. 14 of the applicants were successful. However, of the successful applicants, 15 couldn't make all the training sessions and were discounted. How many were selected to help at the tournament?
Answer:
The statement is a False statementStep-by-step explanation:
This question is somewhat lacking in detail or the information is not properly delivered/presented, this can be seen in the two statements bellow
1. 14 of the applicants were successful
2. Of the successful applicants, 15 couldn't make all the training sessions.
The two statements cannot hold true especially statements two, because if 14 volunteers were successful, then 15 volunteers cannot be selected from 14.

Answer:
The number of apples in the 12th bag is 9
Step-by-step explanation:
The Mean Value of a Data Set
The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:
[tex]\displaystyle \bar x=\frac{\sum{x_i}}{n}[/tex]
Where xi is the value of each data and n is the total number of values.
We are given the value of n=12 and the mean number of apples in each bag (8), thus:
[tex]\displaystyle 8=\frac{\sum{x_i}}{12}[/tex]
Multiply by 12
[tex]\sum{x_i}=96[/tex]
This means the sum of all the values is 96. If we add the existing values from the table, considering their frequency, we have:
[tex]6*1+7*4+8*2+9*3+10*1=87[/tex]
Note the sum should be 96, so the 12th bag must have 96-87=9 apples
The number of apples in the 12th bag is 9

Imagine that you randomly select a sample of 30 newborn infants and find that their mean weight is 8.1 pounds. The population mean of newborn infants is known to be 7.4 pounds with a standard deviation of 1.1 pounds. Would a sample mean as large as 8.1 be more or less likely if N = 10? Why?
Answer: more likely
Step-by-step explanation:
Given that :
Population Mean = 7.4
Population standard deviation = 1.1
Sample mean with a sample size of 30 = 8.1
A sample mean of 8.1 will be more likely with a sample size (N) of 10 because, the sampling distribution gets wider with decreasing sample size and narrower with larger sample sizes, hence, sample mean seems to conform with the population mean when the sample size are very large according to the central limit theorem. Hence, since a sample size of 30 results in a sample mean of 8.1, reducing the sample size will either give a similar sample mean or a sample mean further away from the population mean.

A golfer earned the following scores over several rounds of golf: −3, 2, 0, −1, 2, −4. Jamar says these numbers can all be described as integers, while Sophia says they are whole numbers. Which student is correct? Explain how you know.
Answer: Jamar is correct
Step-by-step explanation:
Integer is a number that is a whole number and can either be positive or negative but it can't be a fraction or decimal. e.g 4, -2, 6, -23 etc.
A whole numbers are zero and other natural numbers such as 1, 4, 23. Negative numbers are not part of whole numbers.
From the statement made in the question, Sophia is wrong while Jamar is correct. The numbers aren't all whole numbers because some are negative.

10+6x = 15+9x-3x
is this one solution, no solution, or multiple solution if one of 2 please tell me what is x
Answer:
No solution
Step-by-step explanation:
Let's solve this equation to see if there are any solutions.
First we need to simplify it;
10 + 6x = 15 + 9x - 3x
Combine like terms:
6x - 9x + 3x = 15 - 10
0x = 5
0 = 5
Zero cannot be equal to 5, so there is no solution

Answer:
$287 per week

Answer:
Constant is Purple
Variable is Grey
Expression is Blue
Coefficient is Red
Term is Green
Equation is Black
Step-by-step explanation:
It is a funny problem
Let us revise the meaning of the given names
Constant: It is a numerical termVariable: it is an unknown quantityExpression: it is a mathematics statement with a minimum of two terms and at least one math operation.Coefficient: it is the number of the variableTerm: it is formed from a variable or a number or both multiplied togetherEquation: it is formed from two equal sidesEx:
3 x² + 5x + 7 = 2a - 5 are called equation
[3x² + 5x + 7] and [2a - 5] are called expressions (algebric expression)
[3x²], [5x], [2a] are called terms
[x], [m] are called variables
[7], [-5] are called constants
[3], [5], [2] are called coefficients
Let us answer the question
52x² - 9x + 36 is an expression ⇒ Blue
9x is a term ⇒ Green
7 is a coefficient ⇒ Red
82 is a constant ⇒ Purple
m is a variable ⇒ Grey
52x² - 9x + 36 = 7m + 82 is an equation ⇒ Black

Find the perimeter??? Anyone?!!!!
Answer:
a.) 2(2x)+2(4x-3)
b.)2(2x)+2(4x-3)=42
Step-by-step explanation:
b.)2(2x)+2(4x-3)=42
distribute
4x+8x-3=42
add the like terms
12x-3=42
move the -3 by adding to both sides
12x=45
divide both sides by 12
12x/12=45/12
x=3.75
and to make sure it's right, plug x into the equation.
2(2(3.75))+2(4(3.75)-3)=42
now multiply/add/subtract everything.
2x2x3.75=15 (This was the 1st set of parenthesis)
2x4x3.75-3=27 (This was the 2nd set of parenthesis)
15+27=42
42=42

2. A drink recipe calls for orange juice and pineapple juice. This equation represents the proportional relationship
between the number of cups of orange juice (r) and pineapple juice (p) in the recipe.
3r= 12p
What is the number of cups of orange juice used for 1 cup of pineapple juice?
a. 1/4
b. 3
c. 4
d. 12
Answer:
a. 1/4
Step-by-step explanation:
3r=12p
Divide the left side by 12 to get 1 cup of pineapple juice.
3r=12p
---- = p
12
So now you have
3r=p
BUT you have to divide BOTH sides by 12 so
3r=p
---
12
NOW you have
3/12 r = p
Simplify.
1/4r = p
So 1 cup of pineapple juice is equivalent to a quarter cup of orange juice!
