Whats the value of 1¹²

velikii [3]

Step-by-step explanation:

Answer is 1, because, your multiplying 1 12 times, so it is

1*1*1*1*1*1*1*1*1*1*1*1=1

even if it was 1 to the power of 100, it's still going to be 1, if the base number is 1, then exponent can be any number and still getting 1.

Consider f(x) = bWhich statement(s) are true for 0 < b < 1? Check all that apply.

Ira Lisetskai [31]

Answer:

The domain is all real numbers.

The function is always decreasing

Step-by-step explanation:

Assuming the given function is

$f(x) = {b}^{x}$

for

$0 \: < \: b \: < \: 1$

Then f(x) is an exponential decay function.

This means that, the domain will be all real numbers.

The range will be y<0

The y-intercept is (0,-1)

There is no x-intercept.

The graph is a decreasing function.

During a rock concert, the noise level (in decibels) in front row seats has a mean of 95 dB with a standard deviation of 8 dB. W

lorasvet [3.4K]

Answer:

$\frac{8}{9} *100= 88.89 \%$

So we have at least 88.89% of the noise level values within 3 deviation from the mean.

Step-by-step explanation:

For this case let define the random variable X as the noise level, we know the following properties for X:

$E(X) = 95 , Sd(X)= 8$

And for this case we don't know the distribution for the random variable X.

But we can use the Chebysev theorem who states that the minimum percentage of the data that lies within k standard deviations from the mean is given by:

$1 -\frac{1}{k^2}, k>1$

So for this case we have that k = 3 and if we use this theorem we have:

$1- \frac{1}{3^2}$

$1- \frac{1}{9}=\frac{8}{9}$

And we can convert this into % and we got:

$\frac{8}{9} *100= 88.89 \%$

So we have at least 88.89% of the noise level values within 3 deviation from the mean.

Suppose that a researcher wanted to measure the federal government's efforts to make the education of its citizens a priority. T

Vitek1552 [10]

Answer:

Step-by-step explanation:

STRENGTHS

1) Budget is a major pointer to a government's commitment in a particular sector. Money allocated for education versus the %GDP will definitely show if education is a priority for the government or not.

WEAKNESSES

1) The major player, (the citizens) is not the determinant in this measure.

2) Without knowing the actual number or estimate of those who would be captured in this budget it may be impossible to know if education was really the priority of the government. Let's say (X) number of persons will benefit from the education budget, if X is unknown then planning would be on assumptions.

3) Budget alone is not sufficient in determining the commitment of the government in a sector. Laws, policies as well play a huge role and in this research laws,and policies are not part of the determining indices.
