Ratio of blue to yellow is 10:7 so 10+17 is total and 10/17 are blue and 7/17 are yellow
if there's 340 balloons then 340×10/17= 200 are blue

The correct answer is 7.2

We can subtract 2 from 4, which is 2.

They're both in the same decimal place, so that is why they are affecting each-other.

What is the point slope intercept form of Y=2/3X -2 and the standard form? pls help asap

Tamiku [17]

Answer: slope intercept is y=mx+b

standard form is Ax+By=C.

point slope form is y-y₁=m(x-x₁)

so y=2/3x+2 is slope intercept

Two cards are drawn from a standard deck without replacement. What is the probability that the first card is a spade and the sec

Verizon [17]

Answer:

The answer is 0.123.

Step-by-step explanation:

You want to find the intersection between P(Spade) and P(Red). Knowing that there's no replacement, the probability will be given by the formula:

⇒ P(Spade∩Red) = P(Spade)*P(Red/Spade)

⇒ P(Spade∩Red) = P(Red)*P(Spade/Red)

Either formula works, but I'm going to choose to work with the first formula.

Therefore:

P(Spade) = $\frac{13}{52}$

P(Red/Spade) = $\frac{26}{52-1}$

So:

P(Spade∩Red) = $\frac{13}{52}$ * $\frac{26}{51}$ = $\frac{13}{102}$ = $0.123$

100 people who were surveyed and asked the question: ``Is fuchsia kinda pink, or purply?'' Of them, 60 believe that fuchsia is `

Kay [80]

Answer:

Step-by-step explanation:

Let the event of people who believe that fuchsia is pink = A

Let the event of people who believe that fuchsia is purply = B

Since 100 people were surveyed, the Universal Set =100
60 believe that fuchsia is ``kinda pink'', n(A)=60
27 believe it is both ``kinda pink,'' and also ``purply.'': $n(A \cap B) =27$
17 think that fuchsia is neither ``kinda pink'' nor ``purply. $n(A \cup B)'=17$

We want to determine the number of those who believe that fuchsia is ``purply'', n(B).

In set theory, we have:

$U=n(A)+n(B)-n(A\cap B)+n(A \cup B)'\\100=60+n(B)-27+17\\100=50+n(B)\\n(B)=100-50\\n(B)=50$

Therefore, the number of those who believe that fuchsia is ``purply'' is 50.
