Answer from: leeenaaa95

Step-by-step explanation:

2/4 + 3/5

LCM = 20

2/4 = 2*5/4*5 = 10/20

3/5 = 3*4/5*4 = 12/20

2/4 + 3/5 = 10/20 + 12/20 = 22/20

Answer from: WhiteWinterRose

24+35= 1 1/10

Solution with Steps

24+35=?

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(2/4, 3/5) = 20

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(24×55)+(35×44)=?

Complete the multiplication and the equation becomes

1020+1220=?

The two fractions now have like denominators so you can add the numerators.

Then:

10+1220=2220

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 22 and 20 using

GCF(22,20) = 2

22÷220÷2= 1 1/10

The fraction

1 1/10

is the same as

11÷10

Convert to a mixed number using

long division for 11 ÷ 10 = 1R1, so

1 1/10

Therefore:

24+35=1 1/10

Hope this helps ;)

i found the life tables for the year 2012.

life table of males at age 30. probability of dying between ages x and x+1

total population:

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:

29–30 . . . . . . . . . . . . 0.001420

30–31 . . . . . . . . . . . . 0.001448

white population

29–30 . . . . . . . . . . . . 0.001005

30–31 . . . . . . . . . . . . 0.001037

white males

29–30 . . . . . . . . . . . . 0.001372

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

29–30 . . . . . . . . . . . . 0.001477

30–31 . . . . . . . . . . . . 0.001503

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old.

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497

Answer from: Quest

e^-kt = n/n0 = 0.79

-kt = ln 0.79

t = - ln 0.79/0.0001

Acompany produces packets of soap powder labeled “giant size 32 ounces.” the actual weight of soap powder in such a box has a normal distribution with a mean of 33 oz and a standard deviation of 0.7 oz. to avoid having dissatisfied customers, the company says a box of soap is considered underweight if it weighs less than 32 oz. to avoid losing money, it labels the top 5% (the heaviest 5%) overweight. how heavy does a box have to be for it to be labeled overweight?
