Why is ratio 2:5 different from ratio 5:2? Please my hw is due time!

1 answer:

7 0

It's different because they're comparing two different ways

Example:

2 red apples, 5 apples in total- The ratio would be 2:5

5 green apples, 2 red apples- The ratio would be 5:2

I don't understand my own example but whatever.

The federal government requires a car manufacturer to have a minimum miles per gallon (mpg) average over the models it makes. Su

valentinak56 [21]

Answer:

25 mpg

Step-by-step explanation:

We have a set of values 19, 21, 22, 28 and 18

The average (which is the mean of the set of values ) is :

19 + 21 + 22 + 28 + 18 = 21.6 mpg out of the government requirement

So we need a value such as the mean become at least 25 mpg

We have to solve the equation:

(19+21+22+28+ x)/ 5 = 25

(90 + x ) /5 = 25 ⇒ 90 + x = 125 ⇒ x = 35 mpg

If we get the mean of the set of values including 35 we have:

(19 +21+ 22+ 28 + 35 ) / 5 = 25 mpg government requirement

Consider a uniform distribution from aequals4 to bequals29. (a) Find the probability that x lies between 7 and 27. (b) Find th

weeeeeb [17]

Answer:

a) 80% probability that x lies between 7 and 27.

b) 28% probability that x lies between 6 and 13.

c) 44% probability that x lies between 9 and 20.

d) 28% probability that x lies between 11 and 18.

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value x between c and d, in which d is larger than c, is given by the following formula.

$P(c \leq x \leq d) = \frac{d - c}{b - a}$

Uniform distribution from a = 4 to b = 29

(a) Find the probability that x lies between 7 and 27.

So $c = 7, d = 27$

$P(7 \leq x \leq 27) = \frac{27 - 7}{29 - 4} = 0.8$

80% probability that x lies between 7 and 27.

(b) Find the probability that x lies between 6 and 13. 

So $c = 6, d = 13$

$P(6 \leq x \leq 13) = \frac{13 - 6}{29 - 4} = 0.28$

28% probability that x lies between 6 and 13.

(c) Find the probability that x lies between 9 and 20.

So $c = 9, d = 20$

$P(9 \leq x \leq 20) = \frac{20 - 9}{29 - 4} = 0.44$

44% probability that x lies between 9 and 20.

(d) Find the probability that x lies between 11 and 18.

So $c = 11, d = 18$

$P(11 \leq x \leq 18) = \frac{18 - 11}{29 - 4} = 0.28$

28% probability that x lies between 11 and 18.

Answer:

Answer for 4th question

b = 7

Answer for 5th question

area= 99sq.in

Step-by-step explanation:

4. area of parallelogram= base × height

28= b × 4

b= 28/4

b = 7

5. area of parallelogram= base × height

area= 9 × 11

area= 9 sq.in

a tank is 4/5 full water . after drawing of 190 litres of water it is just 1/6 full . what is the capacity

xxTIMURxx [149]

Answer:

The capacity of water in the tank is 300 litres

Step-by-step explanation:

Let the unknown capacity be x

4/5 of x-190 litres = 1/6 of x

4x/5-190 litres = x/6

Cross x/6 and 190 litres over the equation sign

4x/5-x/6 = 190 litres

The LCM is 30

(24x-5x)/30 = 190 litres

19x/30 = 190 litres

Cross multiply

190 litres*30 = 19x

5700 litres= 19x

Divide through by 19

x = 300 litres
