In △ABC, m∠A=52°, c=11, and m∠B=19°. Find a to the nearest tenth.
Ugo [173]

From the problem we have

In △ABC, m∠A=52°, c=11, and m∠B=19°.

Draw the diagram with the help of given information, (see the attached image)

Now using Sine Law in the Triangle ABC, we can write

Now from Triangle ABC , we can write

\frac{a}{sin52}=\frac{11}{sin109}  \\

Now simplify , we get

\Rightarrow a=\frac{11}{sin109}*sin52\\ \\  \Rightarrow a=\frac{11}{0.9455}*0.7880\\ \\ \Rightarrow a=9.1676 \approx 9.2\\

A company is developing a new high-performance wax for cross country ski racing. In order to justify the price marketing wants,
andrew11 [14]

Answer:

A)Yes they should market the wax, because it melts before 55 seconds

C) Null hypothesis: mean <55 vs. Alternative hypothesis :mean =55

D) the value is 51.33 seconds

Step-by-step explanation:

The selected samples for the champion are : 57.9, 62.9, 50.6, 50.5,48.2,47.2,50.2 and 43.1

The mean is ;

Sum =57.9 + 62.9 + 50.6 + 50.5+48.2+47.2+50.2+ 43.1 =410.6

Mean= 410.6/8 =51.33= mean

Assuming Significant =0.05 thus applying this level will give you 51.28-51.38

if specifically, the mean time to finish their standard test course should be less than 55 seconds for a former Olympic champion, then the null hypothesis is correct

Then;

Null hypothesis: mean <55

Alternative hypothesis :mean =55

Zach filled 581 one-liter bottles with apple cider. He distributed the bottles to 4 stores. Each store received the same number
butalik [34]

Answer:

a. 145 liter bottles (There were 2 bottles remaining)

Step-by-step explanation:

From this question, the total number of bottles that Zach had to fill with apple cider is 581.

He has to distribute these bottles to 4 stores after filling

The question says each store received same number of bottles.

To get the number of bottles received by each store, we divide 581 by 4

= 581 / 4

= 145.25

Therefore each store gets 145 bottles each and there would be a remainder of 2 bottles

Which of the following is the correct solution to the linear inequality shown below?
Georgia [21]
Correct answer is C.

Line y=\frac{1}{3}x-2 intersects y-axis at -2 and passes through the point (3,-1).

Line must be dashed, because the inequality sign is ">".

Point (0,0) must lie in the solution set because it satisfies inequality y>\frac{1}{3}x-2.

0\ \textgreater \  \frac{1}{3}\times 0-2&#10;\\&#10;\\0\ \textgreater \ -2
