Answer:

vowels : consonants = 5 : 21

Step-by-step explanation:

There are 26 letters in the English alphabet. 5 of them are vowels and the rest are consonants. Therefore the ratio of vowels to consonants can be written as:

vowels : consonants = 5 : 21

We first check if the ratio is in it's simplest form ad it is since the highest common factor of 5 and 21 is 1 so this is the correct ratio.

The Toylot company makes an electric train with a motor that it claims will draw an average of only 0.8 ampere (A) under a norma
Igoryamba

Answer:

Step-by-step explanation:

Given that population average is 0.8 ampere

Sample size = 9

Sample mean x bar = 1.34 A

Sample std dev s = 0.48

H_o: x bar =0.8\\H_a: x bar >0.8

(one tailed test)

Mean difference - 1.34-0.8 =0.54

Std error = \frac{s}{\sqrt{n} } =0.16

t test can be used since sigma is not known and sample size small

t statistic = mean diff/std error = 3.5

df = 8

p value = 0.00404
