3241004551 [841]

Answer:

The procedure emphasizes the idea of the summation of one physical quantity. In this case, X.

Step-by-step explanation:

1. When we add fractions like these we do it simply by rewriting a new one, the summation of the numerators over the same denominator:

\frac{2}{3}X+\frac{4}{3})X=\frac{6}{3}X= 2X

The procedure emphasizes the idea of the summation of one physical quantity, in this case, X.

2) This physical quantity x could be miles, oranges, gallons, etc.

fathers age is 5 times the sons age. if the sum of their ages is 60 yearsm what willbe their ages after 5 years.? step by step p
Vlada [557]

Step-by-step explanation:

let father's age be f yr old and son age be s yr old

f = 5s -(1)

f + s = 60 -(2)

sub (1) into (2):

5s + s = 60

6s = 60

s = 10

f = 60 - 10 = 50

in 5 yr time, father age = 50 + 5 = 55

son age = 10 + 5 = 15

Substance X is found in the bloodstream of humans. A random sample of 75 males had a mean content of 28 ppm of Substance X in th
Mashcka [7]

Answer:

H0: u1 - u2 = 0

H1: u1 - u2 ≠ 0

Step-by-step explanation:

This question requires us to state the hypothesis to be used for this test to know if males and females have the same amount of substance X. I have gone further to also calculate the test statistics too.

Null hypothesis:

H0: u1 - u2 = 0

Alternative hypothesis:

H1: u1 - u2 ≠ 0

X1 = 28, sd1 = 14.1, n1 = 75

X2 = 33, sd2 = 9.5, n2 = 50

We have a 2 tailed test

Alpha = 1-0.8812

= 0.1188

Critical value = 1.56

If z<-1.56 or z>1.56

Reject null hypothesis

Test statistic

= (28-33)/14.1²/75 + 9.5²/50

= -2.37

Therefore we reject the H0 because -2.37 is less than -1.56
