David has a bag of coins. The bag contains 7 dimes, 2 nickels, and 6 pennies. He will randomly select 2 coins from the bag one at a time
without replacement. What is the probability that David will select a dime first and then a penny?

Answers

Answer 1

Answer:

7/15 for dime

6/15 for pennies

Step-by-step explanation:

7/15 because 7+2+6=15 and there are 7 dimes so 7/15.

6/15 because there are 15 coins and there are 6 pennies so 6/15.

15 is the total so 7 and 6 have to go over it.

The area of the triangle △ABC is 12 square units.

The question is incomplete. The actual question is

Triangle ABC is symmetric about the y-axis. Point A is located at (-3,0), and AB is the longest side of ABC. If the perimeter of ABC is 16, what is the area?

What is symmetry?

Symmetrical forms or figures are things that can have a line drawn through them so that the representations on both sides of the line mirror each other.

How to solve the problem?

As could be seen in the figure the triangle  △ABC is symmetric along the y-axis. Hence, the side AC and BC must be of the same length let us call it 'a'. Also, the coordinate of B must be (3,0) because (3,0) is the reflection of (-3,0) corresponding to the y-axis.

And, the length of AB=6 units because the distance between (-3,0) and (3,0) is 6 units.

Now, the perimeter of the triangle is 16 units. Therefore,

2a+6=16

⇒a=(16-6)/2

⇒a=5 units.

Hence, we have an isosceles triangle △ABC we can find the height 'h' of the triangle using the Pythagoras theorem. Consider the triangle  △ACE
then we have that

the height of the right triangle  △ACE= h

the base of the right triangle  △ACE= 3 units

the hypotenuse of the right triangle  △ACE= a = 5 units.

Hence, by Pythagoras' theorem

h²+3²=5²

⇒h²=25-9=16

⇒h=4 (we choose the positive value of h because length is always positive)

Hence, the area of the triangle △ABC is

(1/2)×base×height

=(1/2)×AB×CE

=(1/2)×6×4 unit²

=12 unit²

Hence, the area of the triangle △ABC is 12 square units.

yokoreceived a 70 gift card for a coffee store. She used it in buying some coffee that cost 8.04 per pound. After buying the coffee, she had 45.88 left on her card. How many pounds of coffee did she buy?

Answers

Answer:

Since she started with $80 and ended with with $35,24, we can find the total amount she spent by subtracting these amounts:

$80 - $35.24 = $44.76

This means that she spent $44.76 on coffee. If each pound cost $7.46, we can divide $44.76 by $7.46 to see how many pounds she bought (ignoring tax):

44.76 / 7.46 = 6 pounds of coffee purchased

Answers

Some times it's really very easy to answer the problem just by looking over the given problem.

For the given graph, we need to observe some(or any) point on the graph that can conclude anything to answer the given problem.

Generally we observe x or y-intercepts of the graph first.

Let us observe the y-intercept of the given graph, because we can see a clear picture of y-intercept there.

By looking on the graph, we can see y-intercept is at -1.

Note: y-intercept is a point on y-axis where value of x is 0.

Now let us observe the given functions in the given options.

First option: If we plug x=0 in the given function, we get f(0)=0.

So, y-intercept for first option is 0.

Second option: If we plug x=0, we get a negative -1 inside radical. Cube root of -1 is -1. On multiplying by -1 we get +1.

So, y-intercept for second option is 1.

Third option : If we plug x=0 in that function, we get 0-1 = -1.

So, the y-intercept for third function is -1.

Therefore, function in third option is the correct function for given graph.

Therefore, third option [tex]f (x) = \sqrt[3]{-x} -1[/tex] is correct option.

What is the cubic Function?

A polynomial equation with a 3-exponent greatest exponent is called a cubic equation. Despite having many more uses for understanding more complex mathematics, such as calculus, cubic equations are frequently employed to calculate volumes.

Given a graph of a cubic function for calculating the cubic function we need to standardize it. since it's a single aggregate graph that standard function would be.

x = a(y + 1 )³

for the value y tends to -1. "a" will be  -1.

Hence,

x = -1 (y+1)³

(y + 1 )³ =  -x

y+1  =  ∛-x

y = ∛-x   -1

Therefore, for the given graph F(x) = y = ∛-x   -1.
