Most times, it’s good to talk to your teacher for help. I think it would be a good idea to ask your parent, sibling or any adult for help. Sometimes you think harder than you should so relax and try reading the question again. I hope you figure this out! Good luck!

What is 250/363 in its simplest form

zaharov [31]

You find the GCF of 250 and 363 by factoring. 250 = 5^4 * 2. 363 = 3 * 11^2, and they have no common factors, so 250/363 is already in its simplest form!

Find in degrees. 11 B 6 [?]° Round to the nearest hundredth. Enter

avanturin [10]

Answer:

$\beta = 28.610$

Step-by-step explanation:

in this case we have a right angled triangle, whenever you see this triangle think of the TRIG RATIOS * sin, cos & tan* but if it was another triangle besides right angled triangle you use SINE RULE OR COSINE RULE

SOLUTION

$\tan( \beta ) = \frac{opposite}{adjecent} \\ \tan( \beta ) = \frac{6}{11} \\ \beta = tan(inverse)( \frac{6}{11} ) \\ \beta = 28.61045$

F(x) = x^2, g(x) = 2/3 x^2 comparison

daser333 [38]

Answer:

g(x) is a vertical compression of f(x)

Step-by-step explanation:

Equation of graph 1 : $f(x)=x^2$

Equation of graph 2 : $g(x)=\frac{2}{3}x^2$

f(x)→a f(x)

Its is case of vertical stretch or compression

Vertical stretch if |a|>1

Vertical compression if 0<|a|<1

f(x)→a f(x)

So, $x^2$ → $\frac{2}{3}x^2$

So, $a= \frac{2}{3}=0.67$

So,0<|a|<1

So,It is a case of vertical compression

So, g(x) is a vertical compression of f(x)

Which of the following would increase the width of a confidence interval for a population mean? Choose the correct answer below

Lelechka [254]

Answer:

A. Increase the level of confidence

Step-by-step explanation:

The margin of error is given by:

The margin of error is:

$M = \frac{Ts}{\sqrt{n}}$

In which T is related to the level of confidence(the higher the level of confidence, the higher T is), s is the standard deviation of the sample and n is the size of the sample.

Increase the width:

That is, increasing the margin of error, as the width is twice the margin of error, the possible options are:

Increase T -> increase confidence level.

Increase s -> Increase the standard deviation of the sample.

Decrease n -> Decrease the sample size.

Thus, the correct answer is given by option A.
