What is a equivelent ratio , and a ratio tabel

Mkey [24]

A equivelent ratios are just like equivelent fractions. If two ratios have the same value,then they are equivelent,even tho they may look different! A ratio table is the relation betwen two similiar magnitudes with respect to the number of times the first contains the two.

Sholpan [36]

Answer and explanation:

Given : A driving exam consists of 29 multiple-choice questions. Each of the 29 answers is either right or wrong. Suppose the probability that a student makes fewer than 6 mistakes on the exam is 0.26 and that the probability that a student makes from 6 to 20 (inclusive) mistakes is 0.53.

Let X be the number of mistake

$P(X$

$P(6\leq X\leq 20)=0.53$

To find : The probability of each of the following outcomes.

a) A student makes more than 20 mistakes

i.e. $P(X>20)$

$P(X>20)=1-P(X\leq 20)$

$P(X>20)=1-(P(X\leq 5)+P(6\leq X\leq 20))$

$P(X>20)=1-(0.26+0.53)$

$P(X>20)=1-(0.79)$

$P(X>20)=0.21$

b. A student makes 6 or more mistakes

i.e. $P(X\geq 6)=1-P(X$

$P(X\geq 6)=1-0.26$

$P(X\geq 6)=0.74$

c. A student makes at most 20 mistakes

i.e. $P(X\leq 20)=1-P(X>20)$

Using 'a' part $P(X>20)=0.21$

$P(X\leq 20)=1-0.21$

$P(X\leq 20)=0.79$

d. Which two of these three events are complementary?

The complement of an event happening is the exact opposite: the probability of it not happening.

According to definition,

Option a and c are complementary events.

The function f is such that f(x) = 2x/3x+5 The function g is such that g(x) = 3/x+4 Find fg(-5)

White raven [17]

Answer:

$f(g(-5)) = \frac{3}{2}$

Step-by-step explanation:

Given

$f(x) = \frac{2x}{3x+5}$

$g(x) = \frac{3}{x+4}$

Required

Find f(g(-5))

First, we calculate f(g(x))

$f(x) = \frac{2x}{3x+5}$

Substitute g(x) for x

$f(g(x)) = \frac{2g(x)}{3g(x) + 5}$

Substitute $\frac{3}{x+4}$ for g(x)

$f(g(x)) = \frac{2*\frac{3}{x+4}}{3*\frac{3}{x+4} + 5}$

$f(g(x)) = \frac{\frac{6}{x+4}}{\frac{9}{x+4} + 5}$

$f(g(x)) = \frac{6}{x+4}/ (\frac{9}{x+4} + 5})$

Take LCM

$f(g(x)) = \frac{6}{x+4}/ \frac{9+5x+20}{x+4}}$

$f(g(x)) = \frac{6}{x+4}/ \frac{5x+29}{x+4}}$

Rewrite as multiplication

$f(g(x)) = \frac{6}{x+4}* \frac{x+4}{5x+29}}$

$f(g(x)) = \frac{6}{5x+29}$

Substitute -5 for x

$f(g(-5)) = \frac{6}{-5*5+29}$

$f(g(-5)) = \frac{6}{-25+29}$

$f(g(-5)) = \frac{6}{4}$

$f(g(-5)) = \frac{3}{2}$
