Do the ratios 5:3 and 13:8 form a proportion?

Mathematics
1 answer:
shepuryov [24]3 years ago
4 0

Answer:

  No

Step-by-step explanation:

Each ratio is irreducible, and they are different. Hence they are not the same value, so cannot be a proportion. A proportion is two equal ratios.

  5 : 3 = 40 : 24

  13 : 8 = 39 : 24 . . . . not the same as 40 : 24

_____

<em>Examples of proportions</em>

  5/3 = 40/24 . . . is a proportion

  13/8 = 39/24 . . . is a proportion

Dafna1 [17]

Answer:

A) 0.15

B) 0.36

Step-by-step explanation:

First Box consist 1 red pills and 19 blue pills

second box consist 6 red pills and 14 blue pills

Third box consist 2 red pills and 18 blue pills

a) Prob ( randomly chosen pill is red) = \frac{1}{3} \times \frac{1}{20} + \frac{1}{3} \times \frac{6}{20} + \frac{1}{3} \times \frac{2}{20}

\frac{1}{60} (1+6+2) = 0.15

b)Prob ( 1 reds and 10 blue pilss) =\frac{1}{3} \frac{^1C_1\times ^{19}C_{10}}{^{20}C_{11}} + \frac{1}{3} \frac{^6C_1\times ^{14}C_{10}}{^{20}C_{11}} + \frac{1}{3} \frac{^2C_1\times ^{18}C_{10}}{^{20}C_{11}}

= \frac{1}{3} 1.106 = 0.368

Please help asap I genuinely cannot figure this out
Gemiola [76]

Answer:

C

Step-by-step explanation:

We can use the factored form of the quadratic equation, given by:

y=a(x-p)(x-q)

Where <em>a</em> is the leading coefficient and <em>p</em> and <em>q</em> are the zeros.

We have zeros <em>x</em> = -2 and <em>x</em> = 3. So, let <em>p</em> = -2 and <em>q</em> = 3:

y=a(x+2)(x-3)

Next, we are given that our <em>y-</em>intercept is (0, -30).

In other words, when <em>x</em> = 0, <em>y</em> = -30. So:

-30=a(0+2)(0-3)

Solve for <em>a:</em>

<em />-30=-6a\Rightarrow a=5<em />

<em />

Hence, our factored equation is:

\displaystyle y=5(x+2)(x-3)

For the standard form, expand:

y=5(x^2-3x+2x-6)

Simplify:

y=5(x^2-x-6)

Distribute:

y=5x^2-5x-30

Our answer is C.

Every given minute an ameba is equally likely to do one of 3 things: (1) Die (2) Divide into two (3) Stay the same. If the ameba
nadya68 [22]

Answer:

1

Step-by-step explanation:

we have the probability of dyng = 1.3

we have probability of ying =

p0 = p1 = p2 = p3 = 1/3

d = dying

d=\frac{1}{3} (1+d+d2)

we cross multiply from here

3d = 1+d+d2

3d-d = 1+d2

2d = 1 + d2

(d-1)2 = 0

2d - 2 = 0

2d = 2

divide through by 2

d = 1

therefore there is a a confirmed probability that the ameba from a single cell is eventually going to die out.
