Answer: Sample space for:

Coin (S) ={H, T}

Spinner (S) = {Green, Red, Orange, Purple, Yellow}

All the Possible outcome for:

Coin =1

Spinner = 1

The total outcome there = 7

Probability of flipping tails and not spinning purple or green

=11/10

Step-by-step explanation:

All the Possible outcome for:

Coin =1/2+1/2=1

Spinner = 1/5+1/5+1/5+1/5+1/5=1

The probability of flipping tails. = 1/2

The probability of not spinning purple or green = 3/5

Therefore, the probability of flipping tails and not spinning purple or green

= 1/2+3/5

=11/10

aalyn [17]

Answer: 36.25p + 7.50r = 185

Step-by-step explanation:

The cost of p gallons of paint is given by;

= 36.25 * p

= 36.25p

Cost of r rollers is given by;

= 7.50 * r

= 7.50r

Total the customer can buy with; $185

PLZ HELP I will give the brain!! Which of the following statements is true about completing the square? 1. When completing the

Helen [10]

Answer:

Option 2

Step-by-step explanation:

When completing the square, you have to find the number that will allow you to find the perfect square trinomials and when you factor that it should get the form a^2 + 2ab + b^2 and if a is equal to 1, then to find b, you have to take the half of the coefficient and square it because of the equation, and to maintain a balanced equation, you have to add it to both sides (same to both sides)

Hope this helped.

A tennis racket normally costs $60. The tennis racket is on sale for 30% off. What is the sale price of the tennis racket?

hram777 [196]

The answer would be 42 and here’s how:)

so to start it would be written as this.
___=30% x 60

meaning what equals 30% of 60.

= means is
x means of
___ means what

•so for example if you have this question written out, it would be - what is 30% of 60, and that would turn into the first equation by a substitution method.
• then you have to put the 30% as a decimal. (0.3)
now the equation looks like this.
___=0.3 x 60
• then you would turn it around so it’s 0.3 x 60=

now the answer to that equation is 18.
• so now you have to take the original 60, and subtract the answer amount of 18.

that would look like this. 60-18=___
the answer to that is 42! and there’s your answer! hope it helped!

The spinner is equally likely to land on any of the six sections.

AlexFokin [52]

You have a 2/3 chance.
In this question, it is easier to work with the complement. Since they are not simultaneous events, we will need to add them.

Let's consider the chance at picking a 2. We have a 1 in 6 chance at getting a 2 and since the question is after greater than 4, 4 is also considered part of the complement (1/6).

Now, you have a 6/6 chance at picking any number and since we want it subtracted from the complement, we would have a 4 in 6 chance, which is equivalent to a 2 in 3 chance at picking a number higher than 4 or a shaded region.
