Two customers went to a sports shop to buy baseballs and gloves. Each Baseball cost the same amount and each glove costs the same amount.
- The first customer paid $60 for four baseballs and two gloves
- The second customer paid $84 for five baseballs and three gloves
What was the cost in dollars of each baseball?
Answer:
$6.00
Step-by-step explanation:
Using a system of equations, it is found that each baseball costs $6.
For our system, we are going to say that:
x is the cost of a baseball.y is the cost of a glove.The first customer paid $60 for four baseballs and two gloves, hence:
[tex]4x + 2y = 60[/tex]
Simplifying by 2:
[tex]2x + y = 30 \rightarrow y = 30 - 2x[/tex]
The second customer paid $84 for five baseballs and three gloves, hence:
[tex]5x + 3y = 84[/tex]
Since [tex]y = 30 - 2x[/tex]
[tex]5x + 3(30 - 2x) = 84[/tex]
[tex]5x + 90 - 6x = 84[/tex]
[tex]x = 6[/tex]
Each baseball costs $6.

Answer:
Width = 7, Length = 42
Step-by-step explanation:
Length is 6 times its width, means that it's the same number but times 6 so we'll use "x" for both length and width:
6x · x = 294
6x^2 = 294
divide both sides by 6
x^2 = 49
[tex]\sqrt{x^2}[/tex] = [tex]\sqrt{49}[/tex]
x = 7, width is 7 and length is 6(7) = 42

Question 4
Titus is asked to prove hexagon FEDCBA is congruent to hexagon
F'E'D'C'B'A' in the graph below. Titus thinks that if he transforms hexagon
FEDCBA by (x, y) - (x + 16, y - 10) he can show the two figures are
congruent. Is he correct? Explain why or why not. If Titus is incorrect, what
series of transformations will correctly prove FEDCBA F'E'D'C' B'A'!
I need ASAPPPP
Answer: No, Titus is incorrect.
Step-by-step explanation: Two shapes are congruent when they have the same size and shape, but one is created of rotation, reversion or translation of the other.
So, hexagons FEDCBA and F'E'D'C'B'A' are congruent because they have the same size and shape, however they are reversed and translated from each other, i.e.:
Comparing the coordinates of both hexagons:
F (-6,6) → F' (6, -4)
A (-10,6) → A' (10,-4)
E (-4,4) → E' (4, -6)
B (-12,4) → B' (12, -6)
D (-6,2) → D' (6, -8)
C (-10,2) → C' (10, -8)
We notice that the transformation necessary to transform FEDCBA into F'E'D'C'B'A' is
multiply x-coordinate by (-1);subtract y-coordinate by 10;Therefore, it is (x,y) → ( -x, y-10).
So, Titus is incorrect about the transformations that prove the hexagons are congruent.

please help me with 168÷45
Answer:
3.73 ( The three is infinite)
Step-by-step explanation:
Adam has two brothers, Ben and Chris, and one sister, Daisy. On any given day, Ben calls Adam with Probability 0.3, Chris calls Adam with Probability 0.4, and Daisy calls Adam with probability 0.7. let X be the number of siblings that call Adam tomorrow. Find the expectation of X.
Hint: Express X as the sum of suitable indicator random variables.
Answer:
The expected value of X = 1.4
Step-by-step explanation:
Given that:
The probability of Ben calling Chris = 0.3
The probability of Chris calling Adam = 0.4
The probability of Daisy calling Adam = 0.7
The probability distribution function can be calculated as follows:
P(X = 0) = P( nobody calls Adam)
= (1 - 0.3)×(1 - 0.4)×(1 - 0.7)
= 0.7 × 0.6 × 0.3
= 0.126
P(X = 1) = P(if only Ben call +if only Chris call + if only Daisy call)
P(X = 1) = 0.3 × (1-0.4) × (1-0.7) + (1-0.3) × 0.4 × (1 - 0.7) + (1 - 0.3) × (1-0.4) × 0.7
P(X = 1) = (0.3 × 0.6 × 0.3) + (0.7 × 0.4 × 0.3) + (0.7 × 0.6 × 0.7)
P(X = 1) = 0.432
P(X = 2) = P(if only Ben & Chris Call + if only Ben & Daisy call + if only Chris & Daisy call)
P(X = 2) = 0.3 × 0.4 × (1 - 0.7) + 0.3 × 0.7 × (1 - 0.4) + (1 - 0.3) × 0.4 × 0.7
P(X = 2) = ( 0.3 × 0.4 × 0.3 ) + (0.3 × 0.7 × 0.6) + (0.7 × 0.4 × 0.7)
P(X = 2) = 0.358
P(X = 3) = P(i.e. all three call) =0.3 × 0.4 × 0.7 = 0.084
Therefore; the expected value of X is calculated by using the formula:
[tex]E(X) = \sum x P(X=x)[/tex]
E(X) = (0 × 0.126) + (1 × 0.432) + (2 × 0.358) + (3 × 0.084)
E(X) = 0 + 0.432 + 0.716 + 0.252
E(X) = 1.4
Thus, the expected value of X = 1.4

A measurement template with a historcal value of 25.500 is measured 27 times and a mean value of 25.301 is recorded. What is the percent bias when the tolerence is -0.3?
Complete Question
A measurement template with a historical value of 25.500 mm is measured 27 times and a mean value of 25.301 mm is recorded. What is the percent bias when the tolerance is +/- 0.3?
Answer:
The percent bias is [tex]B = 33.167 \%[/tex]
Step-by-step explanation:
From the question we are told that
The historical value is [tex]S = 25.00 \ mm[/tex]
The number of times it is measured is n = 7
The mean value is [tex]\= x = \frac{\sum x_i }{n} = 25.301 \ mm[/tex]
The tolerance is [tex]t =\pm 0.3 = 0.3 - (-0.3) = 0.6[/tex]
Generally the percent bias is mathematically represented as
[tex]B = 100 * \frac{\= x - \tau }{ t}[/tex]
=> [tex]B = 100 * \frac{25.301 - 25.5000 }{0.6}[/tex]
=> [tex]B = 33.167 \%[/tex]

3. Determine the domain and range for each graph
(-inf, 1]
Step-by-step explanation:Personal comment
Sorry this took so long
In short, you had it flipped, always put your smallest value first and your largest value second.
Reason:
Interval notation is
[(minima, maxima)]
Which is basically saying the minimum and the maximum, and as such you always end up having the smallest value first.
Putting the reasoning together;
A negative is always less than a positive in practice, therefore, your negative infinity should go first.
Hope this helps :)

The proportion 75/w = 150/100 can be used to find the whole 'w' when the part is 75. Will the 'w' be less than or greater than 75? Without solving, explain how you know. *
Answer:
w will be less than 75.
Step-by-step explanation:
Given the expression;
75/w = 150/100
We are to determine whether w is greater than or less than 75.
If you look at the right hand side of the expression, 150/100, you will see that the denominator is greater than the numerator. Due to the equality sign between the fractions, the same will be applicable to 75/w meaning that w will also be less than 75.
Consider the equation and the following ordered pairs: (-2,y) and (x,1).
y = -2x + 3

Q: The table shows the weights of apples at a grocery store. If this represents a proportional relationship, what is the weight of 12 apples? Remember to explain your answer :)
Step 1: So to start us off, because every 5 apples weighs 0.60 kilograms, we're going to divide 0.60 by 5 to get the weight of ONE apple.
0.60 divided by 5= 0.12
Now we know how much a single apple weighs in kilograms and we can move onto the next step.
Step 2: The next step is to times the weight of one apple by 12 because that would give us our answer for the weight in kilograms of 12 apples.
0.12 times 12=1.44
Hopefully, this is correct and helps you! Sorry if I made any errors, it would be best to go back and do the steps yourself just to make sure if that makes you feel any better. Good luck! xxoo
-Sav
Answer:
1.44kg
Step-by-step explanation:
If they are proportional then you can use the unitary method:
If 5 apples=0.6kg then 1 apple=0.12kg as this is 0.6/5 (because you divided the apples by 5 so you have to do the same to the kg)
then you can work out that 12 apples=1.44kg because 0.12*12 is 1.44 and you multiply by 12 as this is what you multiplied the apples by so (becasue they are proportional then you have to do the same to the kg)
hope this helps :)
