3/8 has to sing
8/8 is all
all=haveto+don'thaveto
all=8/8
haveto=3/8
subsitute
8/8=3/8+don'thaveto
subtract 3/8 from both sides
8/8-3/8=5/8
5/8=don'thavetosing
answer is 5/8
Answer: No. Jamies reasoning doesn't make any sense.
Counter example :- Isha decides to go on walk on every 4th day and go for gym on every 2nd day in a month.
Then Isha will do both the things on same day = LCM (4,2)
Now, LCM of 4 and 2 = 4
Therefore, Isha will do both the things on 4th day of the month .
Step-by-step explanation:
Jamies reasoning doesn't make any sense.
Because the LCM of 3 and 6 = 6 not 18[since 6=3×2]
LCM is the least common multiple number of two or more numbers.
Answer:
The null and alternative hypotheses are:
Under the null hypothesis, the test statistic is:
Now, we have to find the right tailed z critical value at 0.10 significance level. Using the standard normal table, we have:
Since the test statistic is greater than the z critical value, we therefore, reject the null hypothesis and conclude that there is sufficient evidence to support the claim that the university students weigh more than the population.
D) <span>In Mrs. Brown's Geometry class there are 15 boys and 10 girls. The students are presenting projects to the class. If Mrs. Brown selects students at random for presentations, what is the probability that the first 2 students chosen are girls? i

We are given that 14 inch represent 38 foot.
To know the model length that represents 1 foot, all we have to do is cross multiplication as follows:
14 inch ..............> 38 foot
?? inch .............> 1 foot
length on model = (1*14) / 38
length on model = 7/19 inch = 0.36842 inch
