Answer:

Hence the study seem to be inconclusive since the probability of getting those result by chance are somewhat very high.

Step-by-step explanation:

The result seem to be inconclusive since the probability of getting those result by chance are somewhat very high.

Since the probability of getting such sample result by chance are very high, we cannot assume that the women have the ability to predict the gender of their babies.

Hence the study seem to be inconclusive since the probability of getting those result by chance are somewhat very high

Sam works 1/5 hour at the register of a store. He works 2/3 hour in the back stock room and 1/2 hour helping customers. How many
AleksandrR [38]

Answer:

Sam worked  \frac{41}{30}  hours that day (fractional answer)

Step-by-step explanation:

The total number of hours Sam worked is the sum of all the three hours given.

Let's add the first 2 using LCM and then add that result with the last.

Firstly:

\frac{1}{5}+\frac{2}{3}\\=\frac{1(3)+2(5)}{15}\\=\frac{13}{15}

Now,

\frac{13}{15}+\frac{1}{2}\\=\frac{13(2)+1(15)}{30}\\=\frac{41}{30}

The hours worked by Sam is 41/30 hours (fractional answer).

To support a tree damaged in a storm, a 12-foot wire is secured from the ground to the tree at a point 10 feet off the ground. T
VARVARA [1.3K]

Answer:

(D)56.4

Step-by-step explanation:

According to the question, Let AB=10, AC=12 and m∠B=90°.

Thus, from ΔABC, using trigonometry, we have

\frac{AB}{AC}=sinx

\frac{10}{12}=sinx

\frac{5}{6}=sinx

sinx=0.83

x=sin^{-1}(0.83)

x=56.4

Therefore, at x=56.4 the wire meet the ground.
