Answer:
For the independent value of 2, the equations generate the same dependent value ⇒ A
Step-by-step explanation:
In the linear equation y = m x + b
x is the independent variabley is the dependent variable∵ y1 = 6x - 16
∵ y2 = 3x - 10
∵ x is the independent value
∵ y is the dependent value
∵ The two equations have same dependent value
→ Same dependent value means equate y1 and y2
∴ y1 = y2
→ Equate their right sides
∴ 6x - 16 = 3x - 10
→ Subtract 3x from both sides
∵ 6x - 3x - 16 = 3x - 3x - 10
∴ 3x - 16 = -10
→ Add 16 to both sides
∵ 3x - 16 + 16 = -10 + 16
∴ 3x = 6
→ Divide both sides by 3
∴ x = 2
∴ For the independent value of 2 the equations generate the same
dependent value
The price of a television is marked down for a weekend sale. After the sale is over, the price of the television is back to its original price. Are the percent of decrease and the percent of increase the same? Explain your thinking
9514 1404 393
Answer:
No. The bases for computing percentages are different.
Step-by-step explanation:
Suppose the original price is $100 and it is marked down 20%. Then the amount of markdown is 0.20×$100 = $20. The marked-down price is then $100 -20 = $80.
After the sale, the price increase of $20 is computed using the base price of $80:
increase % = $20/$80 × 100% = 25%
The percentage decrease and increase are different because they are computed using different numbers as the reference.
__
Additional comment
The closer to zero the percentages are, the closer they are to being the same. A 1% markdown will equate to a 1.010101...% markup, for example.

Answer:
60 passengers.

Stephen Curry makes 43.5% of his 3 point shots. In a typical season, Curry takes around 700 3 point shots. Assume Curry takes 700 3 point shots in the 2020 season, and those shots are independent and can be modeled using the binomial theorem. (Hint: Don't forget the continuity correction!)
a. Find the probability that Curry makes less than 300 3 point shots.
b. Find the probability that Curry makes more than 350 3 point shots.
Answer:
a. Find the probability that Curry makes less than 300 3 point shots.
17. A hemisphere of lead of radius 7 cm is cast into a right circular cone of height 49 cm. Find
the radius of the base of the cone
Answer:
[tex]r = 3.74cm[/tex]
Step-by-step explanation:
Given
Hemisphere
[tex]Radius = 7cm[/tex]
Cone
[tex]Height = 49m[/tex]
Required
Determine the radius of the cone
First, we calculate the volume (V1) of the hemisphere.
[tex]V_1 = \frac{2}{3}\pi r^3[/tex]
Substitute 7 for r
[tex]V_1 = \frac{2}{3}\pi * 7^3[/tex]
[tex]V_1 = \frac{2}{3}\pi * 343[/tex]
[tex]V_1 = \frac{686}{3}\pi[/tex]
Volume (V2) of a cone is:
[tex]V_2 = \frac{1}{3}\pi r^2h[/tex]
Because the lead is cast into a cone, then they have the same volume.
So, we have:
[tex]\frac{686}{3}\pi = \frac{1}{3}\pi r^2h[/tex]
[tex]686 = r^2h[/tex]
Substitute 49 for h
[tex]686 = r^2 * 49[/tex]
Divide both sides by 49
[tex]r^2 = \frac{686}{49}[/tex]
[tex]r^2 = 14[/tex]
[tex]r = \sqrt{14[/tex]
[tex]r = 3.74cm[/tex]
Hence, the radius of the cone is 3.74cm

Solve for Y
ABC = DEF
Answer:
12
Step-by-step explanation:
△ABC ≅ △DEF means that these two triangles are congruent to each other. Congruent triangles also have corresponding sides and angles that are equal to each other!
This means that angle A corresponds to angle D; and thus, we can set up in equation for these two to solve for y.
First, let's try to decipher what exactly we are solving. Y is what we are multiplying by five to get 60°, or angle A (congruent angle).
Now, we just solve it!

Answer:
It means that you need to not use a lot of money on your credit card. When you have cash, you can only use the money that you have while on a credit card, you don't really have a limit to your use of money.
:)
Step-by-step explanation:
Treating your credit card like cash means always spending the money from a credit card carefully, as we do in cash. Because spending exceeding money can cause you in debt.
What are credit cards and cash?
A credit card is a card that is used to spend money that is paid afterward. These cards are issued by banks so that we can spend money when we want to.
It suggests you shouldn't put a lot of money on your credit card. When you have cash, you can only spend what you have, whereas, with a credit card, you have no restrictions on how much money you can spend.
Therefore, treating your credit card like currency entails always spending money from a credit card with caution, just as we do with cash. Because spending too much money can lead to debt.

The value of the equation is A = 2 2/7
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first number be P = 6 2/7
The value of P = 44/7
Let the second number be Q = 2 3/4
The value of Q = 11/4
A = ( 6 2/7 ) / ( 2 3/4 )
On simplifying the equation , we get
A = ( 44/7 ) / 11/4
A = ( 44/7 ) x ( 4/11 )
A = 16/7
Therefore , the value of A is 2 2/7
Hence , the equation is A = 2 2/7
